@2

I felt something slap against my butt cheek, and then again a couple of times. It felt like a hand. I woke up with a jerk. I had drifted off to sleep, only for a few minutes it seemed, as I lay naked on my bed whilst mom had finished her shower. Now she stood over me next to the bed. She had a bath towel wrapped around her, and had been slapping my naked butt with her hand to wake me up.

"This will never do young man," she said sternly. "It's almost 10.30. Why haven't you put any clothes on?" I had drifted off to sleep on my side, so mom must have had a good view of my ass and back whilst she slapped me. As I turned on my back, to now face her, I saw her looking at my balls and dick again, which, for now, was still limp. She licked her lips again. As before, I was sure she was not aware she was doing this and it was almost an involuntary action.

"Oh, sorry mom," I said, apologetically. "Must have drifted off to sleep. I felt a bit sleepy after cumming twice in the bathroom, and lay on the bed for a few minutes to recover, that's all."

"Oh," replied mom more calmly, apparently pacified at my explanation.

"Well, I hope you remember what I said in there. We have some serious talking to do later. I'll probably think things over whilst I'm out. Make yourself breakfast after you put your clothes on. I'll be going straight out when dressed."

As she spoke about dressing, I had a sudden idea.

"Mom, I'm not really in the mood to go out today, now. I think I'll just stay at home all day. I was wondering...er...well...as I'm going to have to dress and undress a few times later when we have our, ...you know...sessions, ...it would just be easier if I...er, ...I mean, ...if I just wore say, my boxer shorts, and that dressing gown I got a couple of years back. You know, the one I've hardly worn. Maybe I could wear it around the house with just my boxers on underneath to save bother. After all, you have seen enough of my body by now."

Mom looked at me in silence for a moment, as if she was considering what I had just said. After a pause, she said, "Well, I guess it doesn't matter if you do, and it would save us some time. As long as we've got no guests coming over, I'm ok for you to dress like that. But only whilst we are having to do our sessions mind, and back to normal after this is hopefully all over," she said in a firm tone. "And, I guess it will save a bit on the laundry," she added, in a more relaxed way, and as if she was giving herself another reason to agree to my request.

With that she started walking out of my bedroom, still with the bath towel wrapped around her.

I lay back on the bed for a moment again. I didn't know where I'd got that idea all of a sudden, and the courage to say it! It just seemed to happen!

I was referring to a 'house-gown' I had bought a couple of year's back -- one of those impulse buys. It was like a dressing gown, but made of fine, smooth fabric, which I couldn't remember the name of, dark blue in colour with an embroidered design over the back. It was really designed for the 'man' who liked to lounge around at home without much on underneath after a shower or bath. Looking back, I don't know why I'd really bought it, except it looked nice in the shop. Mom had refused to let me wear it around the house when she was around, being the prude she was (or I had thought she was), so it had ended up folded up and unused, in my cupboard.

But now, it seemed appropriate enough to wear it, and the circumstances were right! Mom had agreed, and that was great. I got up, slipped on a pair of loose fitting, comfy boxer shorts, and rummaged around in my clothes cupboard until I found the gown.

I put it on and looked at myself in the long mirror in the corner of my room. The gown still fitted me well, going down to just above my knees, and was very comfortable, with a tie-belt around the middle. The fabric was not quite silk or satin, but still smooth and luxurious feeling. The dark blue colour was quite alluring and stylish! I almost looked like some rich guy lounging around at home! I smiled at my reflection in the mirror and posed a bit, and then decided to go down to get some breakfast.

Mom came into the kitchen not long after. She was fully dressed with some make up on, looking ready to go out. She was wearing a beige coloured, fine corduroy skirt, and light brown, lambswool, v-necked sweater, which was quite clingy and showed off the size of her large boobs well. Although the sweater was a v-neck, it sat quite close to her neckline, so only a little part of bare skin under her neckline showed. I could make out the top of a fine gold necklace around her neck, which she sometimes wore when going out. She looked quite nice and 'lady like', and it excited me to see her like that, knowing that I had seen her completely naked not long before.

She looked at me up and down in my house gown for a moment, but didn't say anything, and then put some money on the kitchen worktop.

"I have to do some shopping," she said, pouring herself a short coffee. "I had something to eat earlier, so I'm off now. Here's some money for lunch. Order yourself a pizza or something," she continued. "And see if you can tidy up a bit whilst you're at home, instead of being lazy. Bye." And with that, she took a final sip from her coffee cup, turned and went.

"Bye, mom," I said, as she walked down the hall.

I heard her slam the front door shut and the car starting.

As I sat at the kitchen table, I thought back to what mom had said in our session in the bathroom. It had been a real turn on for me, seeing her completely nude for the first time. And she had let me play with her wonderful butt for a few moments! Fuck! But she had also sussed out my desires towards her body. I felt a little like I had been caught thinking something I shouldn't have. But I just couldn't help my sexual urges! I was a red bloodied male at 18 and seeing her nude body was just a complete turn on for me! The fact that it was my mom...well that just seemed to make it a little more exciting for some reason. Maybe it was the closeness and trust of the relationship.

I wondered what she would do now, and if she would become more strict. But she had also said something about increasing the frequency of our sessions to see just how much I could cum. It was confusing, and felt a slight headache come on as I thought about it. I decided it wasn't worth getting a headache over. There was no point, and I guess I'd find out soon anyway what she was going to do about our sessions when she got back home.

The ache in my balls had eased a bit as I'd cum twice that morning, but I knew it would start up again in an hour or two and I'd be ready to cum with mom, hopefully, still helping. My dick stirred a bit at the thought.

The next few hours seem to fly by. I did a bit of tidying up in the kitchen and living room as mom had asked, as I thought it best to get her in a good mood for when she came back. Then I ordered a nice large pizza and a bottle of coke, all to myself.

After eating, I watched TV. A couple of friends phoned whilst I was watching, and we chatted about this and that. They had no idea what was happening between me and mom at home, and it was going to stay that way.

At around 3pm, I heard mom's car pull into the driveway. I didn't fancy going out in my gown to help her with the bags (and she probably wouldn't want the neighbours to see me like that), so I just opened the front door and picked them up to take into the kitchen, as she placed them inside our porch. They looked mostly like groceries, but there were a few other nicer looking bags, which I didn't see into, which looked like mom had gone downtown to the main shopping mall to buy something.

Mom came in and closed the door. She had a serious look on her, but looked pleased when she saw I had tidied the place up a bit.

"You've done some housework I see, Jacob," she said, looking at me up and down in my gown like she had done earlier in the morning.

"Yea, mom, it's the least I can do right now, as you've been...er....helping me....you know."

Mom looked away from me and got on with sorting out the groceries and her other bags. "I'm going to make myself something to eat," she said, all serious again. "Do you want anything?"

"No," I replied. "I ordered pizza while you were out."

"Well, go and do something for a while and I'll give you a call when I'm ready for our little chat I mentioned we'd have."

"Ok, mom," I said a little nervously, and went off to my room.

I decided to read a book to take my mind off things. After about an hour, I heard mom call me.

I went downstairs and found she was at the kitchen table.

"Sit down" she said.

I pulled up a chair next to her at the table and sat down.

My eyes wandered to her boobs momentarily as they stuck out of her tight fitting sweater, and then back to her face. I think she noticed.

"Jacob, I had a good think whilst I was out today," she started. "Although I had initially agreed to give you some stimulation to help you to cum for medical reasons, it seems that seeing my body has raised some sexual urges in you."

She paused for a moment.

"Now, thinking it over," she continued, "I realise it's only natural for you to react like that, seeing a woman's body in real life for the first time, even if it's the body of your mother. If we hadn't had to go through this routine as Dr. Taylor had suggested, I'm sure you would not have developed such urges towards me, as I am your mother."

I nodded in agreement, going along with what she had said. It sounded good so far, and better than I'd expected. And I wasn't stupid enough to say I had lusted after her body for some years. Not at this point, anyway.

"So," she continued, "I've decided that I am prepared to continue giving you the stimulation you need."

"Thanks, mom," I said, smiling at her, and feeling slightly relieved.

"However," she continued, "From our session this morning, I can see that you do need to work out some of these urges, and it may be of some benefit to include in our sessions some extra activities which will help you to cum." She paused again, letting what she had said sink in.

I was still not sure what she meant.

"I think in order to be able to give Dr Taylor as much information as possible, we need to try to make you cum as much as we can, just to see where your limit is. So far we've stopped our sessions when you are comfortable, rather than seeing how many times you can actually cum. And also it's been a bit awkward during the week, as I'm at work and you're at college."

I looked at her still confused. "So, what do you mean mom?" I said a little hesitatingly.

"What I mean, is that, in order to stimulate you and help you cum as often as possible, over this weekend, I am going to give you constant visual stimulation."

I gulped.

"Er....ok," I said, again not really sure what she meant.

"Which means that I am going to wear clothes and other garments appropriate to do that. I went to some lingerie shops today and bought a few items that may help with our sessions."

Fuck! I couldn't believe what I just heard. A lump developed in my throat, I gulped again and my dick stirred.

"Oh," I said, all innocently.

"I may not wear the lingerie all the time, but I have some other clothes that may do the job in stimulating you," she continued.

My dick was coming to life as she spoke, tenting up in my boxer shorts a little, and because I was just wearing the gown and no jeans, I realised it would soon show. However my crotch was partly under the table, so mom could not see it yet.

"And, it may also help you to cum, to go along with some of your natural urges with regard to my body," she continued.

"Er, ...in what way mom?" I managed to say meekly.

"Well, you tell me what you might like to do when we are having our sessions and I will let you know if that is acceptable to me."

"You mean about touching you," I said.

"Yes, and perhaps a few other things which you may naturally feel like doing."

I swallowed again and my mouth was suddenly feeling very dry. My dick was semi hard now.

"But," she continued, "One thing is totally off limits. You may not ever penetrate me. That would be completely wrong."

I blushed deeply at her words, knowing that she had thought I wanted to do that to her. Fuck, yes I did, but mom knowing that at this stage, felt deeply embarrassing.

"Ok, mom," I said in a high-pitched, embarrassed tone, trying to make out it was no big deal. I felt a tinge of disappointment run through me.

"And one other thing, is that I may do or suggest other things which women normally do to turn men on, which will also help you to cum," she added.

"Like what? "I said, curiously.

"Well, we'll see," she said, a bit mysteriously. "Why don't we wait for our sessions and then it will be more stimulating for you."

As she spoke my mind became flooded with things I'd seen in porn movies or in pictures and I just couldn't imagine for a moment that what I had known as my 'prim and proper mother' doing those to me.

I blushed again and my dick was now raging up.

"Do you feel like you need to cum now Jacob?" said mom, looking down towards my crotch area under the table.

"Well..er....it just so happens mom, that...er...you know....talking about this has...er...kind of...got me going again," I replied.

"Well don't hide it," she said, standing up and pushing her chair along the floor a little so she could sit a bit closer to me and see my crotch area better.

"From now on, you must tell me whenever you are becoming turned on and hard by looking at my body, especially as I will be dressed more appropriately to stimulate you. You must tell me as soon as you get aroused, so that we can do what we can to try to get a sample. We must get as many samples as we can for Dr Taylor, to show her just how much semen you are producing. Is that clear Jacob?"

"Yes," I replied obediently.

"Now, take that gown off."

I stood up in front of her as she sat about a foot away from me. She immediately saw the tent under my gown where my dick was. I undid the tie in the middle of the gown and let it open at the front. My dick burst out, through the gap in the front of my boxer shorts, and pointed directly up at her, the piss slit showing.

She looked at it hard, leaned across and stroked it gently. "That looks nice and ready," she said smiling a little, but still quite business like.

I pulled my gown off completely, and put it on the back of the chair I had been sitting on.

I was now standing with just my boxer's on, and my hard cock pointing through them.

"As I am going to be giving you visual stimulation at all times everywhere around the house, there's no reason we should not be able to collect your samples anywhere too. I'm going to get the semen beaker."

Mom had kept the beaker on a shelf by the kitchen window. She walked over to it, picked it up and came back and sat on the chair in front of me.

"Take off your boxer's," she said in an almost schoolmistress sort of tone.

I pulled them down and kicked them to one side, and my hard cock raged up, as I stood naked in front of her in our kitchen. This really turned me on, being in our kitchen like this, even though mom still had all her clothes on!

"I'd don't want you to cum on my sweater or bra just in case I miss catching it, and we do need to give you as much stimulation as possible, so I'm going to take them off," she said, much to my pleasure.

Mom put the semen beaker down on the table next to us and pulled her sweater off over her head, and put it on the back of her chair. I saw she was wearing a black bra. Then still standing and facing me, she unclipped her bra from the back, putting on the chair over her sweater, and exposing her large hanging boobs, which flopped a bit as she did so. The fine gold necklace which I had noticed earlier, was still around her neck, and it made her look a touch more sexy, as her large swaying boobs hung down below it.

Seeing her like this in front of me, caused my prick to rage up further.

Then she sat back down on the chair so my cock was almost level with her face. Mom started stroking it up and down. As she did so I looked at the nipples on her boobs and the wide areole surrounding them. Boobs like that had always turned me on enormously in my porn collection, and here they were in real life. Fuck!

I wanted to suck on them, but I was still hesitant to do anything different to our routine so far.

"I did say to tell me what you naturally feel like doing from now on," said mom, taking her eyes off my straining cock for a moment and up at me.

I looked down at her, blushed a little, and said, "Er, ...well, ...I'd sort of like to...er...suck on them a little, ...if that's ok with you."

"Well, that sounds quite normal and natural," she said. "You may do so, as long as you don't bite hard on them. Be gentle."

I knelt down so as to be more at eye level with mom's wonderful hanging boobs, and firstly, squeezed and cupped them softly with my hands. Then, I gently licked around her left nipple and sucked on it, taking more of the boob into my mouth as I did so, whilst my right hand caressed her right boob. It felt fantastic and my dick jerked up even more.

Then I moved my mouth over to her right nipple and did the same, this time rubbing and caressing the left boob with my left hand as I sucked on the right one. Fuck! The sensation was mind blowing!

I had heard mom gasp a little whilst I sucked on and played with her tits. "You haven't done this for around 18 years," she said softly.

I was too busy sucking and licking on her boobs to reply.

Then, after a minute or two of this, she said, "Ok, that's enough for now, let me stroke your cock again."

I stood up and poked my hard on towards mom's face.

She licked her lips again. I wanted to ask her to suck my knob, but still felt too embarrassed to do so. Her mouth was close enough for me to feel her breath on the end of my prick. She seemed to be concentrating on my piss slit as she stroked along my shaft.

Then, although I wasn't feeling brave enough to ask her to suck on my dick yet, I had another idea, which I did feel brave enough to say. "Er...mom... can I rub it between your boobs?"

"Yes, that should be ok," she said, almost straight away, much to my relief.

She moved herself forward a bit towards the edge of the chair and held her boobs up towards me, one in each hand. I grabbed my cock with my right hand and started stroking it between the flesh of her boobs in her cleavage. Mom held each tit carefully and firmly in position, squeezing the flesh around my dick and looking down watching me slide my cock between them, and up towards her chin. Fuck, this was great!

As I continued, I could see pre-cum at the tip of my prick, and some of it went on her boobs as I slid between them.

"Go on Jacob, fuck my boobs and cum," said mom encouragingly, all of a sudden.

Fuck! I couldn't believe my ears! I'd never heard her use language like that, and it was really arousing.

I continued fucking mom's beautiful full boobs, watching my pole slide between the fleshy mounds, whilst she held them tightly over my prick, almost like she was making a tit-pussy for them!

"Go on fuck them," said mom again, encouragingly.

It didn't take much more of this, and before long I felt the cum rise in my balls.

"Ok, mom, I'm gonna cum....," I said out loudly to warn her.

Immediately, she let go of her boobs, and grabbed the semen beaker with her left hand. With her right hand, she started pumping on my dick, which was at full stretch, pointing it into the beaker.

The feel of her hand on my dick was ecstatic, and after just a few firm stokes I felt myself spurt."Uhhhhhhh...," I said out loud, as my cum flooded into the beaker.

Mom carried on pumping me, gripping my dick firmly and milking as much cum out of me as possible, whilst I was still hard.

After what seemed like ages, the cum waves finally stopped, and she let go of me. I flopped back onto the chair, feeling light headed and like I needed to sit down due to the high of my orgasm to recover.

"Fuck, that was good," I said with my eyes half closed, and almost automatically. Then, realising I had sworn in front of mom, I opened my eyes and said, "Oops, sorry mom, I couldn't help saying that."

"That's ok," she said, still looking at the semen-beaker. I can understand your relief. I don't mind, as long as you don't get too crude. It is natural. And I did encourage you in a similar way too, which is what women do sometimes to help men cum."

It felt great to hear mom say that and I relaxed a bit more. then I looked at the beaker like she was doing. It was about a third full again. I seemed to be cumming about the same amount each time, even though this was my third session of the day.

"I can't believe you're still producing this much, as it's your third time today," she said. "It's not biologically possible. Surely, you must end up producing less each time by the end of the day? As we've only had 4 sessions per day so far, whilst I was working in the week, I'm sure we can manage more, as it's the weekend. And I'm sure you'll dry up by the time I've finished with you today."

I listened in silence, still recovering.

"Well, I'm going to change into something suitable to keep you stimulated whilst around the house, she said. "Clean yourself up and keep just your boxer shorts on under your gown. She got up, still topless, her boobs swinging freely and sexily in front of her, grabbed her sweater and bra from the back of the chair, and started walking out of the kitchen to go up to her bedroom

"I won't be long," she added as she left.

I watched her ass sway in her skirt as she walked, and I gulped again.

Wondering what mom would come down wearing to stimulate me, and hearing she was going to be like that all weekend was enough to get me going! Fuck! This was all just so awesome!I didn't feel like going upstairs to wash, so I grabbed a few 'wet & wipe' tissues from a tub we kept in the kitchen, and gave my now limp cock a good clean and wipe over, especially around the tip as I pulled back the foreskin a little.

It felt exciting to be naked like this in our kitchen, mom having just wanked me off in here. Then, still in the nude, I walked out of the kitchen, along the hallway, and into our downstairs cloakroom, and flushed the wet tissues I had used to clean myself down the toilet.

As I washed my hands in the basin, I gave myself a look over in the mirror above it.

I almost had a glow about me. All this 'sexual activity', seemed to be a having a real positive effect on me.

Then, I walked back into the kitchen and pulled my boxer shorts on, followed by my house gown, and finally sat down at the kitchen table, waiting for mom to come down.

I started to wonder what she would wear for me. It was still rather amazing that she had said she would be giving me 'constant visual stimulation' over the rest of the weekend, whatever that meant. I could not imagine that she would be wearing sexy underwear for me all weekend, but the way things were going, I guess anything was possible! I hadn't yet even seen her in anything more than her regular old fashioned bra and panties, so the idea that she had gone to some lingerie shops especially to buy sexy stuff for me, to turn me on, was still pretty far out!

But, hey, I wasn't going to complain. It would be like a fantasy come true! As I thought over this, my dick stirred a bit, and I wondered just how much I could really cum. So far it had been four times a day, but I hadn't really pushed myself. But I guessed mom was right, it may well be useful to see where my limit was, and to provide as much information to Dr Taylor as possible about the extent of my seemingly incredulous cum production!

I also wondered just how far mom would let me go in terms of touching her, and perhaps more. But before I could think about this any more, I heard her start to come down the stairs, and I braced myself for whatever stirring sight might befall me as she came into the kitchen.

You could not see directly into our hall from the kitchen table where I sat, so it was only as she came around the corner that I saw her.

My jaw dropped.

Without looking at me, she just walked casually in and went over to the kitchen sink and started doing some washing up, with her back to me.

I just looked and stared, open mouthed, almost in amazement.

Before I tell you what she was wearing, just a short aside. You have to remember that up to now in my life, mom had always been rather 'prudish' in her clothing, being very straight laced and wearing long skirts and tops that would cover most of her body her well, although of course nothing could hide the size of her large boobs. Whatever she wore, it was normally very ladylike and conservative, with a big 'C'. And although she still had a reasonable figure and curves, she would always wear clothes that would never accentuate her largish, but still shapely ass.

But now as I looked at her in our kitchen just a few feet away from me, it was a sight to behold for any big butt and full figured woman loving, red-blooded male!

She was wearing light grey shorts and a low cut, pink blouse, and heels that were as high as I'd ever seen her wear, so that her legs and ass looked really sexy. I hadn't seen her in shorts for many years, but these were no ordinary shorts. They seemed to be made of soft, jersey like fabric that clung to her skin and moulded to every curve. Not only that, but it looked like she had cut them so that about one third of the lower part of her ass cheeks were showing! Fuck!

Her shorts weren't quite 'hot pants', but if you can imagine a mature voluptuous lady with a curvy figure and a largish butt in figure hugging shorts, that exposed about a third of her ass cheeks, that's what she was wearing! And they clung tightly into her butt crack, just to make it look even sexier! Fuck me!

"I know you have a thing for my bottom, Jacob," she said finally in a firm tone, and still with her back towards me, "So I've decided to wear things that will help to arouse you when you look at it."

I gulped.

"It...er...really...er...looks great mom," I said, hesitatingly, feeling my dick move in my boxer's, and not really sure what to say to her.

"Good," said mom, and finally turned around. Then I saw her front properly. She must have taken out one of her very old tops, which had string like shoulder straps, leaving exposed her upper shoulders. Not only that, but it looked like she had cut the fabric around the area which would normally have covered her boobs, so that there was a huge amount of cleavage showing! I could clearly see the shape of them, as they hung under her top. As I looked closer, I could make out her thick nipples protruding through the pink fabric. It looked like she wasn't wearing any bra!

Then my eyes wandered down to her crotch area. Jesus! The soft material of her shorts was so tightly pulled into her crotch that I could see the slight indent of her pussy line. My dick jerked up more in response.

Then, she looked at me hard in the eyes and said, "Oh, and by the way, I'm not wearing any bra or panties under these, in case you don't notice."

Fuck me! My mouth started watering, and my dick stirred in my boxer's again!

Then, before I could reply, she turned around and said, "Now Jacob, as it's almost 6.00pm, I'm going to start getting dinner ready. Just sit and watch me, and when you feel aroused enough to...you know...cum,....let me know, and we'll get another sample."

"Er,.. ok mom," I said. My dick was already moving like a snake under my gown, but it wasn't quite semi-hard yet. I didn't think it would be long though.

Mom walked over to the fridge, opened the large door and bent down to pick something up from the lower shelves. Fuck! Her ass was poking out back towards me, the soft fabric of her shorts stretching and pulling even tighter into and between her butt cheeks, so that her ass looked even hotter, if that could be possible, in those shorts!

"And while I get things ready," she said, standing up again and walking back to the worktop with some salad making stuff, "I want to ask you some questions which might help me to know just how best I can stimulate you, and it may also help to arouse you just by talking about it."

I swallowed again.

Mom stood with her back to me, her ass cheeks partly showing in her 'hot pants', and started cutting up some lettuce and tomatoes.

As she did so, she said, "Tell me Jacob, I know you like my bottom, but I'd like to know just what you like about it." Mom spoke almost like she was teasing me and I blushed.

"Well..er...," I started.

"Tell me honestly," she said. "Don't be shy."

"Well...er...I like the...er...fullness and roundness of it mom," I said, a bit timidly.

"Go on," she said.

Felling encouraged, I continued, "I've...er ...always liked largish asses' mom."

"And why is that Jacob?" quizzed mom. "I always thought men liked smaller, pert and firm, toned bottoms."

Feeling more a bit more confident, I said, "Well, they look nice in photos, but...er...I don't think you can...er...you know...get a nice deep handful of butt cheek with those."

Mom burst out into a little laugh.

"Oh, I see," she said. "And there I was I at my age thinking my butt was too big and unattractive."

I relaxed a bit at mom's laugh and began to feel more conversational. "Well, if it's too big and with lots of fat and cellulite it wouldn't be very attractive to me, but your ass is just right mom, not too big and not too small, and it's also still quite shapely and firm in places. It does sag a little bit, but that makes it even nicer for me, as I ...er...sort of like to see the flesh there jiggle and wobble as you walk, and I don't think you get that effect so much with firm, toned ones."

"Goodness me" said mom, "You do have a lot to say about backsides, and mine in particular!" She still had her back to me and was now mixing the salad in a large bowl and adding seasoning and dressing.

"You do still have quite nice curves, mom," I continued, feeling even more relaxed as we spoke, and like I wanted to tell mom how good looking I thought she still was. "And that's why I've said to you so many times about going out and meeting someone. I know you've been put off a lot with your experience with dad, but I'm sure plenty of single guys around your age would like to meet and date you. You never know, you might meet someone really nice."

Mom became silent and as she finished mixing the salad. She turned around and then walked over to the kitchen table, still holding the salad bowl, her bra-less tits sexily wobbling in her low cut top. She put the bowl on the table, bending forward towards me slightly so that I got an even better view of her cleavage.

"Thanks, Jacob," she said breaking into a smile. "That's nice of you to say so. I might take up your advice, as it's good to hear your opinion on how I look. But for now, we must concentrate on your little problem." She looked at me in hard the eyes for a moment, and then said, "Do you like the way my boobs look in my blouse?"

I swallowed again, and my dick now jerked up hard in my boxer's as I looked down into mom's cleavage right in front of her, and could see her large tits hanging freely under her top, as she had no bra on.

I blushed again, looking at her boobs, and said a little uncomfortably, "Er...yea mom,...er...they look really g...good."

"Do they look sexy?" she said, still holding her bent forward pose.

"Y..yep...they sure do mom," I replied, feeling an overwhelming desire to grab them, but controlling myself.

"Good," she said and stood up straight again and walked back to the worktop next to the cooker. I watched her ass cheeks wobble and swing from side to side in her tight shorts. My dick became a bit harder, but I knew I was not quite ready to cum.

"Do you like boobs too, then?" said mom quizzingly again.

"Yea...sure I do mom," I replied.

"But not as much as bottoms," she retorted.

"Well...I like both," I said blushing a little again. "Especially when boobs are large and...well...a bit floppy and jiggly, like yours mom," I added, to reassure her and truthfully too.

"So that's why you find my body so arousing is it?" said mom, still with her back to me whilst she put some pasta into a pan to boil up.

"Well...er...I like women with...er...full curves," I said.

"You mean voluptuous," said mom.

"Yea, I guess so," I replied.

"I see," said mom. "Well it's a good thing I look the way I do then isn't it Jacob, otherwise I might have had difficulty helping you to cum as Dr Taylor suggested?"

"Maybe," I said, not quite knowing what to say to that.

There was silence for a minute or two.

"Are you feeling aroused yet Jacob?" said mom, finally breaking it. She was now mixing up some pasta sauce and meatballs, still with her back to me.

"Yes, I am," I replied. "I'm hard."

"Well, why didn't you say?" said mom, turning around and looking at me.

"I didn't feel I was quite ready until now," I replied.

"Ok, just wait a minute or two while I get everything ready to go on simmer to cook. We'll have about half an hour then before it's all ready, so we'll have time to squeeze in another session before we eat."

My dick jerked up again in my boxer's and tented up my gown as she spoke.

Mom carried on adding ingredients and mixing the saucepans as she stood with her back to me, facing the cooker.

Then, after a few minutes, she turned around and said, "Ok, that's done. Follow me upstairs." And with that, she grabbed the semen beaker from the windowsill near her, and started walking out of the kitchen.

I got up and followed her, my eyes locked on her ass as she walked.

As I walked behind her up the stairs, I almost started salivating, watching her ass cheeks, which were almost level with my face as she took each step. It looked almost liked she was swinging her hips even more than normal as she walked up, just to give me some extra stimulation! Fuck!

Reaching the top of the stairs, she walked into my bedroom, and I followed.

"I think perhaps we should do things a bit differently now," she said, as we reached the side of the bed and stood next to it. "Rather than have you lying on the bed whilst I wank you off, it may give you more stimulation if we added some variety."

"Er...ok," I said. The tent in my gown was now clearly showing.

Mom looked at it and said, "Well, take your gown and boxer's off and lets, see that nice hard cock of yours again."

Fuck! Mom talking like that was turning me on even more. She sat down on the bed facing me to watch me undress.

I took off my gown and threw it on the far corner of my bed. My hard-on popped out through the front of my boxer shorts as I did so. I pulled them down, and chucked them into the same corner as my gown. Now, I stood naked in front of mom, with my proud, full hard-on pointing up at her.

"I think perhaps we should start with some breast stimulation," she said, and started to take off her top, pulling it over her head. Mom's gorgeous boobs came into full view.

She held them for me, for a moment, pointing them in my direction. She'd never done that before, and it made my hard –on jerk up at her. "Come and play with these lovelies," she said invitingly.

I couldn't believe how eager to please mom seemed to have become.

"Give them a suck, Jacob."

I knelt down in front of her, and like I had done in our session in the afternoon, I gave each one a good suck and lick, paying close attention to each nipple, and caressing and cupping each boob generously, and feeling the wonderful soft flesh of each. This time, mom let me carry on much longer than before. My prick was rampant as I did this, kneeling in front of her.

Then, after letting me do this for what seemed like ages, I was beginning to think mom would now let me fuck her boobs again, like last time, but she surprised me by saying, "Now, Jacob, as you've been so nice to me about my bottom, I'm going to give you a special treat. I'm going to get up and you may give it a feel and a kiss through the material of my shorts."

"Fuck! This was the first time she was letting me kiss her wonderful ass!

Mom stood up, her tits swaying freely and sexily as she did so, turned around so her back was to me and then spread her legs a little and bent over so that her hands were resting on the mattress, with her arms straight for support, and offered me her glorious backside.

Fucking hell! Her pose was really enticing and arousing, and all I could do was just drop to my knees again, so that my face was level with her buttocks, and I just slobbered, kissed and licked the lower part of her ass cheeks that were exposed, like I was some wild crazed animal. Fuck!

"Easy now," said mom, realising I was all over her buttocks like something possessed. "You'll have plenty of chance to do this later too."

Man, hearing her talk like that, rather than calming me down, just caused my prick to rage up even further.

After a moment, I eased up on the way I was kissing the visible uncovered part of her ass, and then started to feel each butt cheek where it was still covered by her tight shorts, and kissed them through the material.

Then, looking more closely at the area where her butt crack was, which now had the fabric of her shorts caught, and tightly stretched in it, creating a sort of 'canal', I realised I could see the indentation of her pussy crack, as the soft, thin fabric was so tight against it. Fuck!

I desperately wanted to kiss her there through the material of her shorts, so I started to kiss all around the outside of her butt crack first and then just let the tip of my tongue gently and lightly touch the fabric that was stretched tightly in her butt crack. Mom did not say anything to object as I did so. I did this a few more times at intervals as I was kissing and feeling up her glorious full ass cheeks through her shorts.

Although I was fully hard now, with my dick raging, I sensed that I was still not quite ready to cum. It was now becoming apparent that it was taking me a bit longer to feel like I could cum.

I think mom, must have also noticed this because she said, "Aren't you ready to cum yet?"

"No, mom," I replied, "Not just yet."

"That's interesting to know," she replied still bent over and posing for me. "Well, maybe some more stimulation is in order. Why don't you slap my butt cheeks with your dick honey? You know, like you did in the bathroom."

That sounded good to me, so I stood up and grabbed by hard-on with my right hand.

Mom was still bent over in the same pose, and now she started wriggling her ass at me a little, shaking it from side to side, as if to taunt me with it.

I started slapping her cheeks hard with my prick, over the exposed lower flesh and then on the covered part of her ass, over the fabric of her tight shorts.

Then looking at the crack of her ass again, where the material was tightly stretched so as to form a valley, I just couldn't help rubbing my cock head along it. It went over her pussy slit, pushing the stretched material there in a little way.

Mom gasped a little, but again did not object.

Feeling encouraged, I did this a couple more times, and on the last of these, I let my cock head linger over the soft, taught fabric that was right over her cunt, and pushed in a bit more. But because of the tightness of the fabric over it, there was no way I could actually enter her pussy. Again, whilst I did this, mom gasped a little, but did not say anything or object. Well, that was it. Doing that, and the incredible sight of her ass as she posed for me, caused the cum rise in my balls, and I shouted out to her, "Ok mom, I'm ready."

She grabbed the semen beaker, which she had put on the bed next to my pillows and turned around quickly and sat on the bed, her tits flopping and jiggling as she did so.

She grabbed my cock, pointed the tip into the beaker and started stroking me firmly.

"Uhh...Uhhh...Uhhhhhhhhhhh....," I grunted out loudly, as I came.

"Yes, baby, cum for mommy," she said encouragingly.

Hearing her say that, just seemed to extend the length of my cum waves, and I carried on spurting, and mom kept on pulling on me, until the pulsations became less and less, until I finally stopped and became limp.

Following her usual pattern, mom wiped the ends of her fingers which had caught some of my cum into the beaker, so as to collect every last drop.

Finally, she held up the beaker up again and said, "Honey, I think I detect a little less spunk than normal. Maybe I'm starting to dry you up a little?"

I had sat down on the bed next to her to recover, and looked over at the beaker. Normally my cum would be up to the lines at least one third of the way up the sides, if not more, but this was one mark below that.

"Maybe," I replied. "That was my fourth time today, and we normally stop at this point. Perhaps you need to stimulate me more the rest of the evening to get me going enough, and ready to cum, to see if I do actually run out."

"Well, I don't think that will be a problem," mom replied, looking at me with a slight smile on her face. "After dinner, I'm going to put on some of that lingerie I bought today, and I don't think you'll be disappointed."

I blushed deeply. Although I was getting used to what we were doing, mom seemed to be taking things to a new level each time, and I still had a tinge of embarrassment about the whole thing.

"Er..thanks, mom," I said gratefully, "To be honest...er...I sort of, can't wait."Mom slapped me on the cheek playfully, smiling, and said, "Ok, come on, clean yourself up and come downstairs. I'm just going to note down this measurement and then go and put dinner on the plates. See you in a few minutes." And with that she got up, picked up her top, and walked out of my room, her tits swaying sexily in front of her as she did so.

I looked at her ass again as she swung her hips, watching it move from side to side in her tight shorts and a twinge of excitement ran through me. This was not just because she was going to dress in sexy lingerie for me in our next session, but also because I remembered that I had touched her pussy slit through the material of her shorts with the tip of my cock, and she had not objected! Fuck me! Maybe I could go all the way!I decided to have a quick shower, put on a fresh pair of boxer's under my gown, and then went downstairs.

Mom was in the kitchen, still wearing her tight shorts and low cut top. She served up the plates and we both took them into our dining room. Mom had already set the table. I was surprised to see a bottle of red wine and two wine glasses there. Mom normally only drank alcohol on special occasions or social events and had rarely allowed me to drink at home, although I did drink if I went out with friends.

"Wine?" I said questioningly, as we sat down.

"It will help to relax you," said mom, without looking at me. "Just think of it as part of the medicinal process of helping you to cum. A glass or two is fine," she added. "And it will help to relax me too. There are two people involved in this after all Jacob, you should not forget that."

I became silent for a moment, thinking about what she had just said, as we ate.

I took a sip of the wine. It was good, and immediately had a relaxing effect on me. My eyes wandered to mom's cleavage, which was clearly showing.

I felt I should say something about her last remark.

"I really do appreciate all your help, mom," I said.

"Thank you for saying so Jacob, but I'm sure most mothers try to help their son's as much as they can."

"I know, but...er....you're really helping so much...in er...you know,...stimulating me."

"What has to be done, has to be done," mom replied. "But, one thing Jacob, although I didn't say anything at the time, you did try to rub yourself on my pussy through my shorts earlier. Remember, you may never penetrate me."

I felt a rush of disappointment go through me.

"But," continued mom, "We can do other things."

My cock stirred.

"Er, like what mom?" I asked, questioningly.

"Well, you say, and I'll tell you if we can. But not just now. Let's finish eating and talk about something else."

We carried on our meal and talked about usual day-to-day things. As I drank more of the wine I became more and more relaxed, and I thought mom did too.

When we finished I'd only had the one glass and mom the same. She said, "We'll have some more wine later if you like. I feel like a bit of a rest now. I'm going up to my room, but I'll call you when I'm ready. Tell me, what colour underwear do you like?"

I blushed.

"Well...er,... I've never been asked that question before, mom, but I guess if you ask me what I used to like to look at in magazines, it would be black. But I like other colours too."

"I'm glad you said black," replied mom, "As most of the lingerie I bought was that colour. I'll let you know when I'm ready. Your turn for clearing up after dinner and the washing up I think!" And with that, she got up and walked out of the room, leaving me sitting alone at the dining table. I still couldn't keep my eyes off mom's glorious full ass cheeks in her shorts as she walked out.

I sat for a moment trying to take it all in. This all still felt a bit like a dream.

I cleared things up, tidied and washed the dishes in the kitchen, and then decided to chill out in the living room, by listening to some music. Recently, I'd got into jazz type stuff, so I stuck on a Norah Jones CD, and laid back on the 3 seater sofa with my legs up, eyes closed, listening to her wonderful tones.

---------------------------

I managed to get to the end of the CD and was about to put another on, when I heard mom call down to me.

"I'm coming down Jacob. Take the wine and two glasses into the living room. We'll have our next session there. Oh, and draw the curtains, please."

I did as she asked, getting the wine bottle and glasses from the kitchen, and placing them on our glass coffee table which was in front of the 3 seater sofa. Then, I pulled the curtains closed.

It might help you to know the layout of our living room. It was quite good sized, about 18 feet wide by 25 feet in length, with a plush light beige carpet, 3 piece cream coloured sofa, comprising two large single sofa chairs and one extra large 3 seater, a fire place in the centre of the wall than ran the length of the room, and a white rug in front of it. We also had some bits of furniture like a hi-fi cabinet, bookcases, various lampshades and the glass coffee table I had put the wine bottle on. No TV of course, as mom only let me have that in my room. We had bay windows at one end of the room and wide glass patio doors at the other, leading to the garden. It was all quite spacious and open plan. I had drawn the curtains at both the windows and the patio doors, just in case we had any nosy neighbours, although luckily we were not very overlooked at the garden side.

I poured some wine into both glasses, sat down on one of the single sofa chairs, which was positioned in part of the room from where you could see the door as someone came in, as well as the entire length of the room towards the patio doors, and waited.

After a couple of minutes, I heard mom coming down the stairs. My heart was beating fast.

Finally, mom came in, and walked straight to the centre of the room and stood on the rug in front of the fireplace, holding the semen beaker in one hand.

Fuck, what a sight!

I had only ever seen photos or movies of women wearing what she had on, and to see it in real life, and that it was my mom, was incredible, and my dick immediately responded.

She was wearing a black, full cup lace fabric bra, a black thong, hold up stockings with lace trims and black stiletto heels. Fuck me! My jaw just dropped at the sight, and my eyes were almost popping out of my head.

As I sat speechless, with my prick now semi hard, mom seeing my reaction, did a twirl and showed me her back and ass. Her thong was thin and tight into her ass crack at the back -- virtually all of her wonderful, full, fleshy white ass cheeks were showing!

Finally, I just couldn't hold myself back and said, "Mom, you...you look really...h...hot!"

She turned back around to face me and said, placing one hand on her hip and striking a sexy pose, "Well that's the whole point, isn't it dear?"

I gulped.

"How's your cock doing?" she asked, in a matter of fact way.

"Er...I'm getting hard mom, but I'd just like to just watch you for a bit if that's ok. You just look so fabulous."

"Tell you what," she said, bending down and taking a sip from the wine glass. "I'm going to walk for a while in front of you up and down the room, so you can have a better appreciation of how I look, and that should help to stimulate you more too."

And with that, mom turned and still directly in line with the way I was looking straight at her, walked sexily away from me, towards the patio doors, going about ten paces or so, almost like a catwalk model.

Fuck! The sight of her sexy ass swinging in her thong, and the way the stockings made her legs look was incredibly hot. I had never realised how much in 'real life', as opposed to magazines or videos, a woman could look so good in sexy underwear, and be so arousing!

Reaching the patio door, mom turned and then started walking back towards me, still swinging her hips as she went, and now letting me get a good look at her from the front. Her tits, although well covered in the bra, still swung a bit die to their size. Wow! What a sight!

When she got to about two feet in front of my chair, which was the closest to me so far, she smiled, turned again and before walking away from me again bent forward slightly, showing me her full ass cheeks in all their glory.

Fuck! That was it! I didn't want to wait for her to do her walk again.

My dick was straining in my boxer's, and before mom could walk away from me again. I said, "I'm ready mom," and stood up, almost throwing my gown off me and yanked my boxer shorts down.

Mom turned to see me standing naked in front of her, my hard-on fully erect and ready for action.

"Are you ready already?" said mom.

"Well..er..mom...you look so hot. I don't think I'm quite ready to cum yet, but maybe some more stimulation would be good. Can I touch your ass?"

"Yes, you may," she replied, "But let me get into a more comfortable position."

She walked over to the back of the other single sofa chair so she faced the rear of it, and placed her hands on the top of the back of the chair for support. Then she bent forward slightly, and said, "Now, you may touch and kiss it."

I followed her and knelt down so that my face was directly in line with mom's butt cheeks. Fuck! What a sight in her black thong! I kissed each cheek in turn. Mom smelled fresh and fragrant. She must have showered for me before coming down. I played with each buttock, squeezing each fully and deeply, intermingled with kissing and licking her flesh there. Then, I ran my tongue a little way into her butt crack, but because of the material of the thong, I could neither see nor touch with my tongue, her asshole or pussy.

My hard on was raging now.

"Can I slap your ass with my cock again mom?"

"You may, but not in my butt crack."

Mom bent over slightly more, as if to position her ass better for me, for what I wanted to do.

Her ass looked so good! All I really wanted to do was pull her thong to one side and ram my hard dick into her sweet pussy, but that was completely off limits of course.

I grabbed my hard on with my right hand and smacked her fleshy ass cheeks with it several times. My precum was leaking out, and I rubbed the tip of my prick onto mom's ass flesh, so that it went on her skin there. Fuck, that felt so good!

Although my precum was visible, for some reason, I still did not feel quite ready to cum proper. As this would be my fifth time of the day, it might take longer, I thought.

"I'm really hard mom, but I don't feel I can cum just yet. I think I need more stimulation," I said.

Mom turned around to face me and stroked my hard on a few times. Her hand on it felt exquisite.

"Well, maybe I should take my bra off," she said, and with that she put her hand behind her and unclasped it.

Mom's glorious, large boobs came into full view. She then knelt down in front of me, her back against the sofa chair for support and said, "Try fucking my tits, that might do it."

Fuck! Hearing her talk like that was a real turn on!

Mom held up her tits for me, so that I could rub my cock between them.

I grabbed my prick with my right hand again and started rubbing it between the beautiful milky flesh of her ample boobs. As she held them from me, her nipples pointed outwards and I could see they were erect and hard. For a moment, I rubbed my piss slit against each nipple in turn, and then went back to fucking her gorgeous mounds

"Yes, Jacob, fuck, my boobies."

Fuck! Her words were such a turn on.

I continued fucking mom's glorious tits as she held them tight over my prick, so they squeezed my shaft as it slid between the flesh there towards her chin.

I still didn't feel like I was going cum, though.

"Almost mom," I said, "But not quite there yet."

Then she said, "Stop, and we'll try something else."

My hard on was still raging, but I stopped fucking her boobs.

Mom stood up and walked to the other side of the single sofa chair, picked up the semen beaker, which had been on the coffee table, and sat down. I followed her and then stood with my hard on in front of her so it was level with her face, as she sat.

"Jacob, as it looks like it's getting harder for you to cum now, as we've done it so many times today. I'm going to try something else. I think it's a good sign that its taking much longer for you now, so what I'm going to do is only to help you cum, remember."

"Er...ok," I said, not sure what she meant.

"I'm going to stimulate your cock with my mouth. But before I do that, I should warn you that most men find it very arousing, and they can cum quite quickly, especially if they are not used to it, like you. But as it is taking you so long to cum now, I think it would be appropriate under the circumstances.

I blushed, and my dick raged up at the thought of what she'd just said.

"Er...ok, mom,...er...thanks." Fuck! This was all still too good to be true!

Mom, then still holding the semen beaker in one hand, beckoned me to come closer to her.

With the tip of my cock about and inch from her mouth, she slowly moved towards it and engulfed the entire cock head with her mouth. The feeling was like nothing I had ever felt before.

Slowly, she took more and more of the shaft into her mouth, and started making slurping noises, as she let her saliva cover my cock, as she sucked on it, almost like it was a lollipop.

Fuck!

I put one hand on top of her head for support as she carried on sucking on me.

Then she stopped her sucking action for a moment, and with the tip of her tongue started lapping at and licking my piss slit, and around my cock head.

Fuck!

Then, after a few moments, she stopped that, and went back to sucking my shaft, taking more and more of it into her mouth.

The sensation of mom's mouth and tongue on me was so wonderful that after just a few moments I felt the cum rise in my balls.

"Ok , I'm gonna cum mom," I said to warn her.

She immediacy stopped sucking on me, positioned the semen beaker correctly and, started pumping me with her right hand. She did that just in time, as shortly, with the sensation of her hand over my shaft, I came in spurts as I grunted and shouted, "Ahhhhh....Uhhhhhhh....Ohhhhhhhhhhhhh."

Finally, as my cum waves subsided, I flopped down on the three seater sofa, my head slightly spinning.

As I recovered, mom said, "Well, not so much this time. I think we may be getting to find out your limits for a day."

I looked over at the semen beaker and saw my cum was about half than normal. I sort of felt relieved, as it seemed to show my body did have a limit.

"That was really good mom," I said. "Your mouth really helped to stimulate me. It was very arousing."

"It normally is for a man," she replied. "I haven't done that for ages. Not since your father left. He always used to like me doing it to him."

I blushed again, still felling a little embarrassed about the whole thing.

This time, mom seemed to notice my blushing and said, "You do seem to go red sometimes when I talk about stimulating you Jacob. You must stop that. This is all for medical reasons, as we need to let Dr Taylor know just how must cum you are producing. You must be more relaxed with me."

"Er...sure mom," I said. "I'll try. It's just that...er ..you know...talking to you and doing these things is sort of hard for me as it's new and not knowing if you're ok with it."

"Well, maybe we'll have to work on that," replied mom. "We'll have to get you used talking more freely with me. We should practice"

"What do you mean?" I replied.

"You may use crude language more with me Jacob. That may help to remove the embarrassment that you feel. Once you are comfortable in doing that with me in our sessions and as we build up to them, I'm sure you will also be able to cum better as it often helps a man to cum when talking like that, and feeling comfortable to talk like that with a woman. As an example, say you want to fuck my tits."

I blushed again. "There you're doing it again," said mom.

"Sorry," I replied. "I want to fuck your tits mom."

"Good. Now say how you like my ass, but in a more crude way."

I thought for a moment and then said, feeling a bit more confident, "I love your fucking ass mom. It's so juicy and fleshy, and I love to rub my hard cock all over it." I felt a twitch of a movement in my cock, as I said those words, even though I had just cum.

"Even better," replied mom. "And do you like fucking mommies tities?"

"Yea," I replied, almost straight away. "Your tits are so fucking hot I want to suck them and play with them and see them bounce up and down and fuck them."

"Good young man. I see we are making progress. Now, tell me that you want to see my pussy."

Fuck! Mom had never mentioned that before and I blushed again.

"Er...," I hesitated.

"I didn't say fuck my pussy, but you can see it if you like, as it may help you to cum more," she added.

I took a deep breath and said. "I want to see your hot pussy mom," and then feeling braver, I added, "I want to see your cunt."

"Good boy!" said mom out loud and looking pleased with me.

Then taking the initiative, I said. "And I want see your hot asshole and lick it."

"Excellent," replied mom, much to my surprise that she had not raised an objection to this. My dick was moving now and mom saw it.

"Good. I can see all this talk is having an effect on you Jacob. But I'm sue you are some time away from cumming again. So let's drink some more of this wine and I'll stay semi naked like this in my lingerie until you are ready again."

I gulped and looking over at mom hard in the eyes, I thought I saw a sparkle there I had not seen in a long time."Go and give yourself a quick wash upstairs," said mom after a moment. "And you might as well stay naked for now," she added.

I got up, my now limp cock and balls flapping a bit, and started walking out of the room. I noticed mom looking at my dick as I went. Just being naked like this in front of her in our living room was exciting, and it sent a tingle through me.

I gave myself a clean in my bathroom, and in double quick time I went back downstairs again.

Mom was still topless, and wearing just her black thong and stockings and sitting on the sofa with a glass of wine in one hand. "I made a note of the amount of cum you produced, whilst you were upstairs," she said. She'd put the empty semen beaker back on the coffee table for our next session. "It's definitely a lot less than before -- about half I'd say, which is a good sign," she continued.

I sat down again on the three-seater sofa, picking up my wine glass as I did so. I took a sip. It felt good. We hadn't drunk that much, so I was relaxed, but not so much that it might affect my getting a hard on.

I looked over at mom and saw her staring at me. "What?" I said.

"Oh, I was just thinking how to best stimulate you again. I think it might be a while before you can cum, no matter what we do. But perhaps we can help things along by trying a few different things, including what you said you wanted to do to me a few moments ago."

I realised mom was referring to the crude things she had asked me to say to her. I felt a twinge in my dick just thinking about it, as mom had said she would show me her pussy and also not raised any objection when I said I'd like to see her asshole and lick it. Fuck! This was just getting better and better!

"Perhaps we can try a few games to get you going," she said, after another pause.

"Games?" I said, confused.

"Yes, games," replied mom. "But these are games that adults sometimes play, and I used to with your father occasionally, when we first married. I haven't for a long time now, but perhaps you'd like to try."

I blushed.

"Stop that blushing, Jacob," she said sternly, noticing. "I did say you must be more relaxed with me."

"Sorry, mom," I replied. "I'm still trying to get used to all this."

"Ok, well, let's start."

She stood up, putting her wine glass back on the coffee table.

"As you like my bottom so much, we can do something called spanking. Have you ever heard of that?"

I thought for a moment.

"Well, I think I've read about it, but the idea never really turned me on. I don't mind trying," I said.

"Good," mom replied. "Now, I'm going to stand with my hands resting over the fireplace mantelpiece, with my ass out a bit, and I want you to give my ass cheeks a smack with your hands."

Mom walked over the fireplace, and positioned herself as she had said. Fuck! The way her ass and legs looked in her black thong, stockings and stilettos was incredibly sexy. I felt a slight movement in my dick again.

Mom's largish, milky white ass looked wonderful, and the wide deep curve of each buttock cheek made a fabulous shaped arch from her lower back to the tops of her thighs. For her age, her butt was still surprising well toned, although she had a bit of excess fat there, but that only added to my excitement.

I stood next to her on her left, but one step back, and gave her left buttock a light slap with my right hand. I saw the flesh of her ass cheek ripple a bit as I did so, and I enjoyed seeing that.

"Harder, Jacob, that was too light."

"But I don't want to hurt you mom," I replied.

"Just do it a bit harder," she said. "I'll tell you if it hurts me or not, and to stop if it does."

I slapped the same cheek again, only this time a bit harder. It actually felt a bit more satisfying.

"That's right, Jacob" said mom, "Like that. A touch harder if you like."

I continued, this time slapping the right buttock. I never thought I might enjoy this, but seeing the flesh of mom's ass cheeks ripple and wobble as I did it, was quite enjoyable. Then I noticed a slight, momentary tinge of redness on the white flesh caused by my slapping and that excited me too.

"Oh, yes" said mom, appreciatively.

Fuck! She seemed to be enjoying it. It was the first time she had indicated getting some satisfaction out of our sessions.

I decided to go along with her and try to encourage her pleasurable remarks, so I said, "Do you like that mom?"

"Yes, Jacob, very much. I always used to enjoy it when your father slapped my butt. He also used to say crude things to me whilst he did it, as that used to get him going. Why don't you try, that, your cock might respond."

Hearing mom say this was quite a turn on. I had always thought of her as so 'prim and proper' in my life so far, until just a few days ago, but I never realised she used to get up to this sort of stuff!

"Sure mom," I said. I was starting to feel quite confident now. I moved to her right side, still behind her, so that I could use my left hand for a while.

I slapped her cheeks, one after the other again with my left hand. As I did so, I said, "Fuck yea, mom, I love slapping your large backside. It's so fucking hot."

For a moment, I couldn't believe I had been so crude, but mom seemed ok about it as she said encouragingly, "That's right Jacob, tell me how you like it, and what you want to do to me to make you cum."

My dick responded almost immediately to her words, getting a bit of life into it, but I was way off being properly hard yet.

Then, feeling the urge to kiss mom's ass, I knelt down behind her as she stood, and kissed and felt her butt cheeks almost like I was worshipping them. Satisfied momentarily, I then let my hand wander down to the tops of her stockings, over the slightly rougher elastic lace trim, and then slipped them down, over the stockings, feeling their silky smoothness, as I felt each leg, one in each hand.

Then, I slid my hands back up along the stockings, onto the flesh of mom's thighs, and finally back over each butt cheek, squeezing and caressing deeply each one as I did so. Mom's legs, thighs and ass felt so good!

Mom must have appreciated the feel of my hands on her, almost massaging her lower body as I ran my hands over her, as she said softly, "That felt really good Jacob."

Finally, I stood up again and mom turned around to face me, so I could see her glorious boobs now as well.

Mom appeared to have a slight tint of red on the cheeks of her face like she had been blushing herself, but I didn't say anything.

"That was good. Have some more wine," she said.

We both picked up our glasses and took a sip. I was starting to feel a little tipsy now, and I was sure the alcohol must have be getting to mom too, as she had drunk about the same amount as me, and I was bigger, physically, in frame to her.

"Now," she said. "It's my turn."

I sort of looked aghast, not knowing what she meant by that.

"Er....," I said.

"I mean it's my turn to give you a spank. Just try it. If you don't like it tell me," she said. "Get into position like I did."

I didn't think I would really enjoy being spanked myself, and in any case I had thought all this was about me being able to cum. Then I remembered that mom seemed to have liked feeling up my ass when we had our sessions in the bathroom, so I guessed this might be part of her way of getting some enjoyment. I decided to oblige, as I realised, if mom ended up getting something out of this, then it might lead to us going much further."

I positioned myself like mom had done, with my hands on the mantelpiece and stuck out my ass a little towards mom, who was now behind me.

She started giving me light slaps at first. I wasn't really getting anything out of it as she did so, but after a minute or so, I liked the slight tingle as she slapped me.

"Ok, Jacob?" she asked.

"Yea...fine mom," I replied.

"I'm going to do a it a little harder. Tell me if you don't like it."

Mom slapped my ass cheeks in turn again, this time a bit harder. This time for some reason, the slapping seemed to have more of an effect on me and I felt my dick respond a little. I didn't know why.

Then between the slaps, mom ran her fingers along my butt crack, just tickling it, which felt pretty good too. It seemed like she had been a bit of an expert at this in her time. Finally she gave my ass a good feel and rub over. Then, before I could turn around she said, "I'm going to give your bottom a kiss, like you did to me."

My dick definitely responded to this and twitched a bit, although it was still not hard.

I felt mom, kiss me gently on my ass. It actually felt really nice. She kissed over it a few times, just gentle kisses, unlike my slobbering over her butt!

Then, she said to my surprise, "Turn around, I want to suck your cock and see if I can make it hard."

Fuck! I couldn't believe she had just said that. Quickly, I turned around, to see mom on her knees in front of me, a sight I could hardly have imagined a week ago, ready to take my cock into her mouth.

Before she did anything, she looked up at me for a moment and said, "Well, as you are taking so long to get hard this time, I think this is the only way."

Then without further ado, she took my limp prick into her mouth and started sucking on it. Fuck! The inside of her warm wet mouth on my dick felt so good, that blood started to rush to it, and I could feel myself get aroused and harder.

After about a minute or two of her sucking on me, I was semi hard. I knew I wasn't ready to cum yet though. Then I had an idea.

"That feels really good mom," I said, "But I think I need more stimulation. You did...er...say that I could see your pussy didn't you?"

Mom hadn't looked up at me as I said this, as she seemed to be engrossed in sucking my cock.

Then after a moment she stopped sucking me and said, "Ok, but first I need some more wine. Just stay as you are."

I don't know if it was because the alcohol would give her more courage, if she needed it, or if she was just enjoying herself, but still kneeling, she reached over to the coffee table which was next to us, picked up the wine bottle, filled her glass right to the top and then took a large sip of it. Then she said an extraordinary thing.

"Jacob, I do like wine and sucking cock at the same time. So I'm going to dip your cock head into my wine glass and then suck it. You don't mind do you?"

Fuck! Did I mind? Did my 'prim and proper' mother really say that? I didn't care. I found the idea so arousing, that I just nodded my head, almost lost for words that she'd said, what she had just said.

Mom brought her wine glass next to my cock, which was now semi hard, but still pointed down a little as it was no way fully erect, grabbed my cock with one hand and dunked the tip of it into her wine glass which she held in her other hand, so my cock head was submerged in the wine about one inch. Then, lifting my cock out of the glass, she immediately took it in her mouth to suck the wine off it. Fuck me!

I felt the blood rush to my dick again, and I became slightly harder seeing her do this. Then she stopped sucking me for a moment, took another sip from her wine glass which she had been holding on one hand all this time, and then repeated the whole thing. She dunked my now slightly harder cock into her wine glass again, lifted it out, sucked on it for a moment, and then took a sip from the glass again.

"Mom, that looks so hot," I finally said, unable to hold myself back.

"Good. That's the whole point and I enjoy it too. Now, perhaps it's time for you to see my pussy young man, and we'll see if we can get you to cum."

She put her wine glass down and as she did so I picked up mine and took a sip. I needed it after that, and to prepare myself for what was to come!

Mom stood up and without any hesitation, slipped off her thong and chucked it on one of the sofa chairs. She was now standing before me in just her black stockings and stilettos. Fuck, she looked so hot!

I looked down at her pussy and saw the neatly trimmed pussy hair, which I'd noticed before, during the only time I'd seen it, which had been in the bathroom.

Then mom said, "Sit down over there." She pointed to the three seater sofa. I did as instructed, and mom sat herself down on the single sofa chair, which was a few feet away.

Then, instead of just sitting, Mom leaned back a bit, raised her knees slightly and opened her legs, more and more, until they were almost splayed wide open. Her pink pussy came into full view. Fuck, what a sight! My dick responded by hardening even more.

Then, mom put her index finger in her mouth to moisten it, and inserted it into her pussy. It was like she was playing with herself to stimulate me.

"Wow, mom," I said. "That looks really hot."

"Good" she replied, and looking at my prick which was getting harder and harder.

Mom continued playing with herself, exposing more of her pink pussy flesh to me as her fingers played and poked her cunt and she opened her pussy lips for me.

I just felt like getting up and kissing and licking it, but I wasn't sure if she would allow me. I knew she would not let me fuck her.

I don't know if she had read my mind, but after a moment she said, "Tell me what you want to do when you see my pussy like this Jacob."

I was in such a state of arousal now that my hesitation to say anything had gone out of the window, and I just said confidently and almost greedily, "I'd sure love to lick your cunt mom. It looks so fucking hot. Can't you see how hard my dick is now?"

"Good boy," said mom, smiling, in reply. "You seem to have become much more confident now, which is a good sign, and means you should be able to cum more easily. Ok, you can lick it, but nothing more. But before you do I want to have a suck on that lovely cock again, it looks so good now it's fully hard."

I got up in a flash and went over to mom's sofa chair, my hard on swinging in front of me as I did so.

Mom sat up properly again and grabbed the base of my dick with one hand and took the cock head into her mouth, slurping and sucking on it. Then, she licked around my piss slit with the tip of her tongue, before taking the shaft into her mouth again. She really looked as if she was really enjoying this now.

Maybe it was the wine, or maybe she had now just let herself go a bit, as if she had been holding herself back from expressing the fact that she was being turned on in our sessions so far.

"That feels so good mom, your mouth on my cock is so nice. Suck it yea, go on," I said encouragingly.

Mom responded by sucking me harder and continued like this for a few more moments.

Finally, I said, "I sure would love to lick that juicy pussy of yours."

Mom stopped her sucking of me, and looked up at me. I saw her eyes seemed to be slightly watery and I immediately became a bit concerned.

She said, "Jacob, I haven't sucked a cock like this for such a long time and you've probably realised it is quite arousing for me. I hope you understand. I am feeling a little embarrassed at myself. I am your mother. Will you forgive me for being like this."

I saw mom appeared a little upset, yet she was also being turned on by what she was doing. I didn't know whether it was the wine that had finally got to her, but she seemed to be fighting her own feelings.

Still looking at her hard in the eyes I said, "Please mom, don't feel embarrassed or bad about it. I do understand. Just think of it like me being turned on my your body, but in reverse. Just do what you feel like. I don't mind at all. You are helping me to cum after all, and I'm not surprised if your getting turned on too."

Mom smiled at me and then, got up. "Ok, I still want to suck you until you cum into the beaker. We can lick each other at the same time Let's do a 69 position. Do you know what that is?"

I nodded, remembering I'd seen it in movies, but never having actually done it in real life.

"We'll do it on the rug in front of the fireplace," she said. "Lie down first, and then I'll lie on top of you."

I did as instructed. The rug was quite large -- about 8 feet long by 6 feet wide, so we could easily lie on it.

As I lay there, I realised I would be able to see mom's asshole and pussy properly for the first time - fuck!

Mom picked up the semen beaker, and then straddled over my head. As she did so, the wonderful insides of her ass crack came into full view. Her puckered asshole and wide lipped pussy were just inches from my face. Fuck!

"Is that ok Jacob?" she asked.

"Wow, mom, your ass looks amazing! Back down a little more on me."

Mom wriggled her ass down over my face a bit more until finally I could lick her, whilst I had positioned my arms and hands in away that I could feel and stretch her buttocks wide open at the same time. I could also feel her large fleshy boobs rubbing against my belly, as she had positioned herself on me. Fuck, this was just awesome!

I took in the smell of her pussy juices and they excited me, and I started licking at it. It felt amazing! As I did so, mom had started to suck my cock again. This was heaven!

After licking around mom's juicy cunt for a few moments, I moved to her asshole and started lapping and licking it with the tip of my tongue. Then grabbing her ass cheeks firmly, I stretched and pulled her butt cheeks wider so I could I dart my tongue deeper into her asshole, almost like I was fucking it with my tongue. I could feel the walls of her tight rectum as they rubbed against the tip of my tongue. I was loving it!

Then I went back to her pussy and lapped at it, letting my saliva flow freely, and even took her thick protruding pussy lips into my mouth to nibble. Fuck!

Mom had been working her mouth and tongue on my cock expertly at the same time as I had been doing all this, and I finally felt the cum rise in my balls.

"Not long now mom," I said to warn her to have the semen beaker ready.

Hearing this mom, seemed to want to give my cock an extra hard and deep suck and in doing so, I knew that was it.

"Ok, anytime now," I said.

Finally mom stopped sucking on me and, although I could not see it as her wonderful ass was smothering my face, she must have positioned the semen beaker to catch my cum. I felt her hand start pumping me and then, as I grabbed and stretched mom's fabulous fleshy butt cheeks at the same time, and licked deep into her pussy, I exploded. I had to force my head back down onto the rug as I came, and shouted, "Ahhh...Ahhh.....Ahhhhhhhhhhhhhh."

I don't know how much I had cum, but my orgasm had felt really good. This was the best yet. I felt mom still stroking my dick gently, as she must have been trying to get the last few drops of cum into the beaker. As I lay with my head on the rug all I could see as I looked up was the sight of mom's beautifully large ass cheeks and her puckered asshole and wide open cunt which I had lusted after for so long, still hovering over me. I could stay in this position forever!

Then I remembered what she had said about being aroused herself, and I realised things might be about to take a big turn in the way we did our sessions. I felt the need to give mom more satisfaction. Maybe she would agree to me penetrating her. I wondered....."You've got a fabulous ass mom," I said, as mom's fine open ass cheeks with her asshole and wide open cunt with lips hanging down, still hovered above me.

"Thank you dear," she replied, as she milked the final drops of my cum into the semen beaker.

Then, as if to tease me further, she pushed her butt down on my face and wriggled her pussy and ass cheeks over my nose and mouth, as if she was trying to wipe her ass over me, and then lifted her butt up again.

"Wow, mom, you sure know how to tease me with it," I said, in response to that.

"Well, now I know how much you like it, I might as well put it to good use."

Finally, she lifted her leg up over me and turned and sat on the floor, looking at me, whilst I still lay on the rug. Her large hanging tits, looked incredibly sexy as she sat there, kneeling on the floor.

Mom held up the semen beaker again for me to look at. There was only a small amount of cum in it this time.

"Well, I think you might have reached your limit for today," she said. "And I'm a little tired too. I think it's time for bed."

The wine had got to me a bit now, and I nodded in agreement.

"I think tomorrow, as it's Sunday, we'll review how much cum you have produced so far this week. And we have an appointment with Dr Taylor on Monday. Make sure you get a good night's sleep and your strength back for our sessions tomorrow." Then she kissed me goodnight on my cheek.

With that mom got up and started walking out of the room. She still looked incredibly hot wearing just her black stockings and nothing else! I wondered if I should ask her to wear just those and nothing else for me again tomorrow. That would do!

After mom left, I got up a few moments later, and went up to my room. In no time at all, I fell asleep.

---------------------------------

I felt something nudging my arm and awoke sleepily. Mom was sitting on the bed in her dressing gown, smiling as she woke me.

"Morning, Jacob," she said brightly.

"Morning, mom," I replied, yawning.

Then I felt a bit of a draught, and something touch the lower part of my stomach. Mom had removed the duvet and was sliding one hand over my stomach down towards my cock in my pyjamas.

"Let's have an early session," she said keenly. "I've brought the semen beaker."

I couldn't quite believe she wanted to help me cum so early, but my sleepiness soon disappeared hearing her talk like that.

Mom pulled down my pyjamas, exposing me fully from below, and threw them in the far corner of the bed.

Then, without further ado, she bent down her face towards my still limp cock and started sucking on it. Fuck! I couldn't believe how keen she seemed this morning, almost like she wanted sex!

The sensation of mom's wonderful wet mouth, tongue and lips on my dick had an almost immediate effect and I became hard as she sucked me.

"Ohhh....That's nice mom," I couldn't help saying out loud.

Then, seeing me get hard so quickly, mom stopped sucking on me, stood up, untied her dressing gown and let it fall to the floor. She was completely nude underneath, and her voluptuous, sexy figure came into full view. She stood there for a moment with one hand on her hip, striking a sexy pose, with one leg slightly angled, and her full, hanging, sexy boobs facing me in all their glory. Her thick, protruding nipples were erect, indicating she was aroused herself.

"Well, as you are hard already, let me give you something to keep you going," she said teasingly. "Your cock tastes so good this morning, that I want it to last as long as possible before you cum," she added, much to my surprise at her forwardness.

Mom stood next to the bed about two feet from me near the head end, and turned around to show me the wonderful round globes of her ass, and then sexily wriggled her butt cheeks for me from side to side as she stood on the spot, making the flesh there wobble and jiggle. Fuck! That looked so good! Then, as if knowing what effect this would have on me, she parted her legs a little and bent forward so that I could see her pussy and asshole. And then, even more incredibly, she placed her hands on her ass cheeks, and pulled them apart wider, so I got an even better view. Fuck!

Jesus, she was really going for it this morning, getting me really worked up!

Mom held this pose for a while, adding to my arousal by wriggling her ass from side to side occasionally, and then saying, "Like what you see? Does my ass look good like this?".

The sight of mom posing like that for me was enough to make me say, "Fuck, yea mom, I just gotta taste your asshole and pussy now, you look so damn hot. Please can I?"

Hearing this mom stood up properly again and said, "Yes you may, but only if you let me suck on that juicy cock of yours again. I hope you realise young man that I am now starting to get turned on too by all our activities."

This was the first time I had heard mom admit she was getting turned on too, by what we had been doing to help me cum. I nodded, but did not say anything, so as to not make it seem like a big issue.

I got off the bed and stood up. Mom knelt down in front of me and took my erect cock into her mouth again, making slurping noises as she sucked on it, and playing with my balls with one hand. She seemed to me, to be getting as much out of all this now, as I was!

I didn't feel like cumming yet, which was good, but the sight of mom's tits wobbling and jiggling from side to side as I looked down at her whilst she sucked me, was really turning me on.

Finally, after satisfying herself on my prick and balls for a few moments mom said, "Ok, special treat time. I'm going to get on the bed on my hands and knees, with my ass in the air, and I'll let you play with it. You may lick my pussy and asshole, but no penetrating me, remember!"

Mom stood up and then clambered onto the bed on all fours, facing the window, so she was sideways on the bed with her ass pointed back towards me, sticking up in the air. Fuck me, what an amazing sight! Never could I have imagined a few weeks ago that my 'prim and proper' mom would be posing like this for me on my own bed. It was almost all my dreams so far, come true!

The shape of mom's large wide open buttocks, and the crack between her ass cheeks with her asshole and open cunt and lips hanging down, looked so inviting, that immediately I knelt down on the carpet, so that my face was level with her open butt, and I just started licking and salivating along her entire ass crack. I ran my tongue greedily along the insides of her buttocks, moving from asshole to cunt and vice versa, whilst I grabbed and squeezed a full handful of each butt cheek, one in each hand, as I did so. I was in butt heaven!

Then, satisfied for a moment at tasting her ass crack up and down, I decided to concentrate on her pussy for a while. Mom was wet, and I lapped at her cunt and pussy lips, opening it up with two fingers by stretching them wide apart and tasting the pinky, moist flesh on the inside there. She tasted wonderful!

"Oh yes," she cried as I did this. This was the first time she had openly responded to my licking her pussy. "Yes, Jacob, lick mommy's pussy. Taste all my dirty cunt juice."

Fuck! Her words really spurred me on, and my dick responded by jerking up more.

Then, I moved my tongue up to her asshole and gently darted my tongue into it a little way, as I spread her ass cheeks wider apart for better access. Seeing her brown puckered hole open up and stretch further as I did so, I darted my tongue a little deeper into her ass this time, almost like I was fucking it with my tongue.

Mom groaned in pleasure as I did so, pushing her butt back into my face, apparently very sensitive to my tongue fucking her asshole.

"Ohhhh....Ohhhhh...yes.. baby...lick my asshole. That feels sooooo....gooood."

I continued, responding to her pleasure by pushing apart her butt cheeks further so I got even better access, and tried to go as deep as I could into her asshole with my tongue.

"Ahhhh..." mom groaned again in pleasure.

Then, after a moment, I moved back to her cunt and licked and lapped at it some more. Fuck, this was good!

I was dying to plunge my dick into mom's open wet cunt, now, but I knew she would not agree. But I could also sense she was really in a lustful state, the way she had been wriggling her ass back into my face as I licked on her pussy and asshole.

As a second best measure I said, "Can I slap my dick against your butt and along you ass crack? I promise I won't penetrate you."

"Ok," she said, much to my surprise.

My dick jerked up in response to this.

I slapped my hard on against mom's buttocks for a few moments, wiping my precum on them as my piss slit slid over the flesh on each, in turn. Then, the sight of her ass crack being so tempting, I rubbed my cock head against her asshole, almost tickling it.

Fuck that was so good, I almost felt like cumming but held myself back. Mom had not objected to my rubbing her asshole with my dickhead, so feeling braver, I moved it with my hand slowly along and gently tickled mom's pussy lips with it, which were hanging down. God, her open pussy was so tempting, and just centimetres away from my cock head. I just wanted to shove it straight in!

Then, to my surprise, mom, who must have been so turned on my what I was doing, said, "Ok, Jacob, I can't stand this anymore. Stick it in my cunt, but don't cum inside me. We need to catch your cum in the beaker still!"

Fuck! I couldn't believe it! This was music to my ears! Without further hesitation, I pointed my straining dick directly at her gaping pussy hole, and shoved it in.

"Ahhhhhhhhh...," I cried out in ecstasy, feeling mom's pussy walls grip hard onto me.

I pulled back instinctively, and then shoved in again.

"Ohhh...yess," I said.

Mom was also now groaning in pleasure as I did this. I carried on pumping her, now a little faster, as I grabbed her hips for support. The feel of mom's pussy around my dick as I penetrated her, in and out, was wonderful! Imagining fucking was one thing, but actually doing it was a hundred times more pleasurable!

I was in the throes of ecstasy now and didn't care about anything, let alone making sure my cum went into the semen beaker.

I think mom was also in an extremely heightened sexual state as she was moaning and groaning with pleasure, pushing her pussy back into me as I shoved my cock in at each thrust.

"Fuck me, yes...," she said out loudly.

I was now moaning loudly too, and I just couldn't stop myself cumming quickly, it being the first time, no matter what happened next. I felt the cum rise in my balls, and I exploded inside her, feeling my spunk spurt thickly and deeply inside mom.

"Ahhhhhhh......" I shouted as I came.

Mom responded with a huge moan of pleasure too, as I carried on spurting inside her.

Finally after what seemed like ages, I stopped cumming and felt my cock go limp and I collapsed on the bed next to mom, who was now laying on her front with her eyes closed.

I had finally fucked mom and cum inside her too!

It felt like ages before either of us spoke.

Mom broke the silence by saying in a quiet tone and without looking at me, "What have we just done?"

I didn't say anything for a few moments. Then I replied in a quiet tone too, "I couldn't stop myself, and neither could you I think."

There was silence for a while again.

"You're right," she said after a few minutes. "Never mind, it's happened now. I guess it was bound to happen at some point. We'll have to just get on with it. And we've missed getting a sample." Mom paused for a moment, as if thinking.

Then she said, "Maybe we can work out an average sample based on all the results from the past week. But, you must promise me Jacob, that you will never tell anyone about what we've just done. Not ever."

"I won't mom," I replied sincerely. "Never."

"Good, I feel a bit better about it then." She paused again. "And maybe if we do it again to help you to cum, it won't matter so much now, as we've done it once," she added, much to my surprise.

Fuck! That sounded unbelievable! Mom was ok for us to fuck again!

"But you must try to pull out next time," she said, "So I can get a sample."

"Ok, mom" I replied, "I'll try, but it might be hard, as it's so new to me," I said, truthfully.

Mom didn't reply.
