@4

I was still limp. And I thought I should say something about that.

"Sorry, I think maybe because I'm in a strange place, I'm not worked up enough just yet," I said truthfully.

"Marge, do you provide any stimulation for your son? For example, do you let him touch you?"

Mom hesitated for a moment. I could sense she was unsure just how much to let on. Then she said. "Well sometimes I do. I let him touch my bottom and sometimes my breasts too, as that can help him to cum quicker."

"Well don't let me stop you then. Just do what you normally do," said Dr Taylor encouragingly.

Mom turned her ass towards me a little and I started to caress it through her skirt. My dick responded a little, but I was still not really getting properly hard.

"I think perhaps you need some more stimulation," said Dr Taylor, after watching this for a few minutes, and seeing I was still not getting properly hard. "Tell me Marge, do you let Jacob see you partly undressed?"

I knew mom was fighting her feelings not to tell the doctor too much, but to my surprise at her openness she finally said "Well as you been so frank and open with us doctor, I will also be honest with you and say yes. Occasionally, I have let Jacob see my breasts and my bottom. But I would always wear some panties to cover my crotch area," she added, lying. She obviously didn't feel comfortable to reveal any more just yet!

"Well, may I suggest you remove your top and skirt in that case so Jacob can be properly stimulated? I think he does need more help, poor thing," said Dr Taylor sympathetically.

Mom stopped wanking me and started to unbutton her white blouse. She then took it off, revealing a white full cup bra underneath. Then, she unzipped her skirt from the side and let it fall to the floor. She was wearing quite conservative white panties underneath which didn't reveal much of the flesh of her ass. She picked up her skirt and placed it on the sofa with her blouse.

She was now wearing just her white panties and bra with black medium height heels. She came back over to me, and not looking at Dr Taylor, perhaps to avoid eye contact because of how she was now dressed in front of me, pulled her panties into her ass crack partly, so as to make her ass look more sexy, and then began stroking my dick again.

"That's quite a nice touch, to make you look more stimulating," said Dr Taylor pointing to what mom had done with her panties in pushing the fabric into her ass crack.

"Well, he does like bottoms a lot, so he tells me," replied mom, to my surprise, revealing one of my likes.

"Well that's quite natural," said Dr Taylor smiling at me.

I started stroking mom's ass again, which was now looking much more alluring, but Dr Taylor looking on at me from one side was not helping my erection still.

I think the doctor noticed my discomfort.

"I think we need to do something else here if we are to get you going young man," she said. "I did say I was the type of sexual counsellor who believes in a hands on approach, so what I can do if you like is to stand nearer you Jacob, and you may also touch my bottom lightly through the material of my skirt, as you like bottoms so much. Are you ok with that Marge?"

"Er...yes sure," replied mom.

Dr Taylor removed her white coat to reveal surprisingly low cut beige blouse and dark brown knee length skirt underneath. She came and stood next to me about level with my chest so my right hand could reach her ass. She was much rounder in shape than mom, and more of a bubble butt, I noticed, despite her chubbiness.

"Now don't be shy young man, you can squeeze and feel my bottom as you like whilst your mom does her bit."

I couldn't quite believe this was happening. With my left hand I was feeling up mom's ass cheeks as she stood in her underwear to my left and with my other hand I was stoking Dr Taylor's ass through the material of her skirt as she stood to my right!

My dick started to become hard and responsive finally, although I still felt a little awkward.

Dr Taylor placed the semen beaker on the couch so mom could get hold of it in time.

Then to my surprise mom said. "Dr Taylor I hope you won't mind, but I'm going remove my bra so Jacob can see my boobs. That normally does the trick at home."

"Well, I am glad to hear you have such an informal arrangement," replied Dr Taylor looking more pleased now.

Mom unclasped her bra and threw it on the sofa. Her glorious, full, melon like globes with large brown areole came into full view. Mom's thick nipples looked exceedingly tempting and suckable.

"And I must say you have a very fine pair of boobs," said Dr Taylor seeing them in their glory.

"Thank you."

Before going back to working on my dick mom lent over my face so her boobs were in reach of my mouth. I don't think she had planned to do this but just did it instinctively. Seeing this, Dr Taylor said, "And I see you let him suck you too. Excellent! That should really do the trick. Look!"

Dr Taylor pointed at my dick, which was now fully hard, as I had taken mom's juicy tit into my mouth as she let her boobs fall over and stroke my face, and she saw it's full length and hardness now for the first time. "Jacob, you do have a fine erection. I am going to call it a cock if you don't mind, as I think it is easier to help you to cum if we use more common words."

Dr Taylor keenly looked at my hard on, and licked her lips, and I could see she wanted to touch it. "Can I make a suggestion?" she said.

"Go on," said mom.

"How about if you stand over Jacob like you are and let him play and suck on your fine boobs, and I collect the semen sample? It may make things easier," said Dr Taylor.

"Sounds ok to me, " said mom. "You ok with that Jacob?"

I nodded. It would be good to have another woman's hands on my dick.

I was started to feel much more relaxed being in the doctor's presence now, as she seemed to be enjoying what we were doing too. She moved over to my left where mom had been standing and mom came over to the right of me, still leaning over me slightly so I could suck and play with her boobs or ass with one hand.

Mr Taylor started to wank me. The feel of her hand on my dick was quite exquisite and her technique arousing. She was clearly an expert in this from the way she was stroking me!

My dick was now at full stretch, but I did not feel like cumming just yet.

"May I touch your bottom again Dr Taylor?" I said, feeling brave.

Without saying anything, Dr Taylor angled her ass back at me so I could reach it, and I started to grope at her fleshy ass cheeks through he material of her skirt.

"That's right. Feel my ass young man and cum for me," said Dr Taylor as she continued to wank me, whilst I felt up her butt.

At that moment I would have loved it if either mom or Dr Taylor had given my dick a quick suck. But I did not feel brave enough to go so far as to suggest that.

Mom then surprised me again by saying, "Let me use my boobs on his cock for a moment. That should do it finally."

Mom moved down the couch a little so she was now opposite to Dr Taylor a who let go of my dick, and let mom wank me with her boobs as she held them tightly around my prick and moved up and down.

Dr Taylor looked on pleasingly. "I'm so glad to see you are so free with each other in this way," she said.

Seeing mom do what she was doing to me in front of the doctor triggered something off inside my head, and I started to get extremely aroused now at the idea of mom sexually pleasuring me in front of someone. I'd gone from being very shy about it initially, to now getting really turned on by it, and I felt the cum rise in my balls.

"I'm gonna' cum in a minute if you carry on like that," I said out loud.

Mom continued wanking me between her fleshy tit mounds for another minute or so and then stopped and let Dr Taylor take over. The doctor grabbed the semen beaker in one hand and started pumping my dick hard up and down. She was just in time as after just few strokes I came, gushing into the semen beaker.

"Ahhhhh..AHH...OOOOOHHH," I shouted out as I came, jerking my hips upwards several times as I did so.

Dr Taylor continued to expertly hold my cock and pump me until my cum waves subsided and she'd collected all my cum in the beaker. I pushed my head back against the couch and closed my eyes, enjoying the high of my orgasm as the doctor's hand still held my dick, and mom stood topless, wearing just her panties, next to her. Fuck, that was so good!"Well, that must feel a lot better," said Dr Taylor, as I opened my eyes from the high of my orgasm. "And you've produced quite a lot of semen too," she added, pointing to the semen beaker.

I looked at her, then mom, standing next to the doctor, still topless, wearing only her black panties. I couldn't quite believe what we had all just done together, but I nodded, as I was a little lost for words.

Mom looked at the beaker too for a moment, and then seemed to become self-conscious standing there almost naked in front of the doctor and said, "Excuse me, while I put my clothes back on." She picked up her bra, blouse and skirt in turn, and I watched as she put her clothes back on.

It was just as sexy watching mom dress as undress, seeing her put her bra and blouse on and then slide on her skirt with a wiggle.

Dr Taylor looked at me and said, "You should dress too Jacob. I am finished with you for today. Both of you, please come and join me in my main office when you are ready."

I jumped off the couch and went back into the bathroom. I cleaned myself, and put my clothes back on.

When I entered the 'inner' consultation room again it was empty. I guess both mom and the doctor were back in the regular consulting room.

I joined them, opening the interconnecting door and walking in.

The doctor had her white coat back on and was sitting behind her desk again with mom on a chair in front of her. It hardly seemed possible that a few minutes ago they had both been helping me to wank off, they looked so prim and proper sitting there!

Dr Taylor smiled at me as I sat down next to mom.

"Jacob and Marge," she started, "I am so glad we have managed to get a sample today, and that you have felt comfortable enough to provide one in my presence. And I am so pleased to see you are comfortable with each other in a situation where you are both nude and a little sexual," she said.

And then looking at mom directly, she continued, "I'm especially pleased with you Marge at how helpful you are to Jacob." I guess she must have been referring to mom taking off her bra and playing with my cock with her tits. "Most people would not understand, but I do," she added, smiling at us both.

I saw mom blush just for a moment, but then regained her composure.

"Now," continued Dr Taylor, " I am very hopeful you can proceed to the next stage of the suggested treatment, but I do understand that may be a little difficult. I am going to give you the contact details of three ladies who I believe will be more than happy to help you Jacob, should you and your mom choose to proceed that way. However, if you need my help in getting to the next stage if you'd like to try it between yourselves, then do let me know," she added, looking at mom in particular.

It seemed rather extraordinary, the matter of fact way, the doctor had just said she would help mom and me to have intercourse, but that's what she had just said!

Mom and I both listened in silence and then mom said, "I will think about it and let you know Dr Taylor. It is something quite unusual you are suggesting. Thank you for your kind offer to assist though."

Dr Taylor smiled and then began writing on a piece of paper.

I guessed she must have been writing the contact details of the 'ladies' who I could go and see to have sex with. Fuck - what a thought! My dick became semi hard again in my pants at the idea!

After a few minutes, Dr Taylor finished writing, and folded the piece of paper up and put it in a white envelope she took out from a drawer next to her.

"I've written the contact details of these ladies together with some additional information which may help you decide who to see. You may see any one or all of them. I will let them know you may give them a call, but give it a couple of days before phoning, so I can let them know in advance you may want to see them. These are all quite delightful women, who have been clients' of mine for a number of years and who I can assure you will be most supportive to your needs, Jacob. I have sent them numerous young men of your age and slightly older, and they have helped tremendously in the treatment of the various conditions of those men.

Dr Taylor paused for a moment. "However," she continued, "I would just say that, as you may expect, these ladies came to see me originally because they have high sex urges, which were not being satisfied. Because of this, some of them have particular...," she paused again for a moment, "....fetishes. Do you understand what I mean by that Jacob?"

"Er...," I replied meekly, not sure quite what to say.

"By that I mean, some of these ladies have particular things they like to do in relation to sex. You will find that many ladies, especially those with high sex drives and of a mature age, who are still sexually active, enjoy particular things which help them to orgasm, in addition to just normal sex."

I just nodded again, trying to take this in. Fuck! My dick twitched again in my pants.

"Now, I must see you again next week for a sample, or possibly sooner if you would like my help in any other way for the next stage of your treatment," said Dr Taylor getting up, indicating the consultation was over. "Remember, you don't need to take cum measuring samples at home anymore -- just once a week with me from now onwards."

Mom and I both got up and shook the doctor's hand in turn, and we said our goodbyes. The doctor had given mom the white envelope containing the ladies' details as we left.

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

As we sat in the car driving home, I was dying to open the envelope, but thought it best to leave it till mom raised the subject.

Mom was silent for a while and then said, "How did you feel giving a sample in front of the doctor?"

"I was a bit uncomfortable at first," I said truthfully, "But in the end, strangely enough, it was a bit of a turn on doing it in front of her."

"Yes, I felt the same," mom replied, much to my surprise. "I wasn't sure at first, but when we got going, I started to get quite turned on too by the end. If we hadn't had to keep our secret from the doctor about how far we've actually gone in getting your samples at home, I would have sucked and fucked you right there."

I was slightly taken aback by mom's words, but hearing her talk like that started to get me hard again, and a streak of lust ran through me. I had never imaged mom saying something like that.

"Well at least we know what is wrong with you now, and what needs to be done to get you fixed," she continued. "I'm not sure if I'm comfortable about you seeing other women yet though. I suppose the good thing is that they've all got medical checks from Dr Taylor and will have no STDs, so you won't catch anything. Let me think about it for a bit though."

I felt a little disappointed as mom said that, but I hoped she would come round to the idea.

"But, I have a another plan or two for now," she continued. "Let's make another appointment with Dr Taylor and pretend we'd like her to help us go to the 'next stage' as she put it. You know, about you penetrating me."

I listened in silence, and my dick carried on growing in my pants.

"We need to let the doctor think it's her that helps us fuck for the first time, as I wouldn't want her to know we've already done it. And then perhaps we can see her a couple of times a week and do it in her presence, as it was a bit of a turn on. Dr Taylor looked quite up for it and keen about the idea, I thought. And you never know, she might get a bit more involved as she let you touch her today. She seemed to like my boobs for some reason too. What do you think?"

My dick was now straining, hearing mom talk like that and my cheeks flushed red.

"Why are you blushing Jacob?"

"Er..well," I said meekly, "I'm just getting really turned on hearing you talk like that mom...and...er....well...my dick is really straining in my pants now."

Mom looked down for a moment at my crotch while she drove and saw my cock tenting up my pants as I sat.

"Oh, you poor thing," said mom. Then, with her eyes back on the road ahead, and one hand on the driving wheel, she put her hand nearest me on my crotch and rubbed my hard cock firmly through the fabric of my trousers.

I gasped at her touch. Fuck! I almost felt like cumming there and then!

"If you carry on like that mom, I'm gonna cum in my pants," I said honestly.

"Well, we can't have you doing that," she replied. "Try to hang on honey as we're almost home, and I'll sort you out then. And we won't have to worry about getting samples in that silly semen beaker now, as the doctor said. So you can cum normally, wherever you like."

Fuck! Man, this was turning out to be such a hot conversation, I really did feel like whipping my dick out whilst I sat in the passenger seat of our car, and wanking myself off, hearing mom talk like that! Luckily, however, whilst my dick was still straining, mom turned into our road, and shortly after, pulled into our driveway.

Mom quickly got out and so did I, albeit a little awkwardly, trying to hid my hard on with my hands in case any nosy neighbours were looking.

We got inside our hallway and mom closed the front door and then the inner porch door.

As soon as we were in, much to my amazement at her speed, mom pushed me back against the wall, knelt down in front of me, and started trying to unzip my pants!

It was a little awkward as my hard-on was stretching the fabric, but she seemed to manage it as she pulled my pants and boxers shorts down to my ankles, and out popped my now semi hard dick, finally free. Immediately, she took it in her mouth and I became fully hard in an instant, as she started sucking me frantically. Fuck! My lust was raging due the way mom had come inside the house and started giving a blowjob like some sex mad nympho.

I grabbed her head and hair as she pumped my dick with her mouth, taking me in fully to the hilt as she almost gagged on it.

"Yea, suck it mom. Fuck - that's so good," I said, in heaven.

As I had been dying to come earlier in the car, it didn't take long, and within a few moments I spurted.

"Ohhhh....,AHHHHH....AHHHH," I groaned as I came, gushing a bucket load into her mouth, pushing myself back against the wall for support. She expertly clamped onto me as I came, swallowing everything I fed her. God, that felt so good!

My eyes had closed as I had cum, and now I opened them and saw her cleaning my now limp dick. Then, she stood up and said, "Mmm...that was lovely. I hope you're feeling better now." And then she gave me a peck on the cheek, and started walking up the stairs.

"I'm going for a shower now. Why don't you have one too and I'll see you downstairs later for something to eat," she said, as she went, leaving me half naked with my pants ands trousers still around my ankles.

I made myself decent and sat down on the next to bottom step of the stairs as I recovered from my orgasm. Fuck that was so amazing!

I looked through the frosted inner porch door at the daylight outside and thought about what had happened at Dr Taylor's consultation in the afternoon. That had been really hot too, and all that stuff about me having to have sex regularly as my treatment, and with other women as well!

Then, I remembered the envelope containing the contact details of the other ladies Dr. Taylor had said I could call. Mom had put it on the back seat of the car and left it in there when we came into the house in a rush.

I got up, picked up the keys mom had put down on the table next to the door and went out to get it.

I came back in, shut the door behind me and was about to open the envelope when something made me stop. I'd better wait do it in front of mom, I thought. As she had said she wanted to think about it for a while, it might put her off if I appeared too keen.

I decided to go up and shower.

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

After showering, as I dried myself off and walked naked back into my bedroom from my en-suite bathroom, I heard mom from across the hallway in her bedroom call out loudly, "Honey, have you finished in the bathroom?"

"Yea, sure have mom," I shouted back, so she could hear. "I'm just gonna get dressed."

"Are you naked?" she called out again.

"Er..yes," I replied, "I'm just drying myself off with a towel."

"Well, come in here and do that. Don't be shy."

I paused my drying for a moment and my dick stirred. Maybe mom had other plans before we went downstairs to eat. It had been about forty-five minutes since I came in mom's mouth earlier. I reckoned I could cum again now.

I was by now quite comfortable being nude in front of mom, so I casually walked out of my room, rubbing my hair dry with the towel as I did so.

As I walked into mom's bedroom, my dick seemingly having a life of it's own, although still limp, had filled out a little, and flopped from side to side with a bit of a swing.

I had my eyes half covered as I walked in as I was still drying my hair, but as I pulled the towel away from my eyes, a hot, horny sight greeted me.

Mom was on the bed, with her back half propped up by the headboard. She was naked and had her legs wide open with her pussy lips pulled apart, so I could see the pink flesh inside, and she was playing with it, with one finger of her right hand. She looked damned fucking hot!

Sexily, she said, "Don't you want some of the medicine the doctor ordered?" and smiled at me.

Fuck! How could not! I threw the towel on a chair, and clambered onto the bed on my knees towards the centre of mom's wide-open legs.

"Lick me first honey," she said, gently.

I bent my head down between her thighs and started to lick her. She tasted wonderful. I lapped around her pussy lips and then stuck my tongue in deeper into her fuck hole, darting it in and out, like I was fucking it with my tongue.

Mom writhed in pleasure and groaned, "Mmmm...Oh yes...Jacob...that soooo.. nice..."

I continued lapping her pussy, and she closed her thighs around my ears and head almost pulling my face into her crotch with them.

I was now clamped onto mom's delicious pussy with my mouth, sliding my tongue in and out, and up and down the wet, juicy pink flesh there. I must have touched a sensitive spot, as she cried out louder than before, "Ohh...Ohh...yes, honey...that's it...oohhh."

Mom let go of clamping my head with her thighs. I lifted my head up and looked down at her thick pussy mound, with the lips hanging invitingly. I had an urge to put my finger in.

"Can I finger fuck you?" I said eagerly.

"Go on," she said, "Then stick that hard cock in."

I gently prodded her pussy with my middle finger, and enjoying the sensation, I added a second finger. Mom writhed on my fingers, pushing herself onto them.

My dick was now rock hard and straining, I wanted to stick it into her.

After a few more moments, I raised my arms and pushed mom's thighs back, revealing her wet open cunt. It looked really inviting

"I'm gonna fuck you now, mom," I said determinedly.

"Do it baby," she replied, her eyes closed.

I positioned my knees between mom's thighs and pointed the tip of my dick towards her pussy. Then, I rubbed my dickhead along it, as if teasing her, and finally pushed in.

"Ahhhh..." I cried as I did so. Mom's pussy walls grabbed the sides of my rock hard prick as I pushed all the way in, and started pumping, in and out.

Fuck! This felt so good!

I held the top part of the middle of mom's thighs as I fucked her. My chest was at about 45 degree angle to her as she lay below me, and my dick penetrated her deeply as she held her thighs wide open. Mom's large tits wobbled below me as I started to slap into her with my groin and balls as I pumped.

Then, I put my elbows down either side of her chest, and as I pumped her with my dick I saw her open her eyes, and for the first time, I wanted to kiss her as we fucked. I lay my chest flat on her boobs and brought my lips down to her's and we started to French kiss. Our tongues worked inside each other's mouths greedily and sexily for what seemed like ages. I continued pumping her, and then we broke our kiss as I straightened up again and placed my hands on her thighs.

"Go on, fuck me Jacob," she said, now looking directly at me. "Fuck me, and cum inside me. Mix all your creamy prick juice with my cunt's. That's what we want."

I continued pumping in and out, and I knew it wouldn't be long now.

"Come on," she continued, almost taunting me to cum inside her."

"I'm going to let you fuck me whenever and wherever you like now," she continued, tauntingly. "We can do it all the time and in front of the doctor. And if you satisfy me enough, I'll even let you fuck your aunt Jean and other women. Come on fuck me, cum in side me..."

And that was it for me. Her lewd, hot words did the trick, and I came, big time. "Uhhhhh...Uhhhhh...Uhhhhh..." I cried out, shooting deep inside her, wave after wave of my spunk.

Finally, I collapsed in a heap on top of mom as she wriggled beneath me, and wrapped her arms around my back in an embrace.

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

After a few moments, I turned to lie on my back naked next to mom. I was just coming off the high of my orgasm, when I recalled what she had said last of all as we had fucked.

"Mom, what did you say about aunt Jean? Did you say you would let me fuck her? What do you mean?" I said.

Mom rested her head on her elbow and stroked my chest as she spoke. "Well, that was something I was going to speak to you about later as one of my plans. I might as well tell you about it now."

I listened intently, enjoying the sensation of mom stroking me.

"You know, I mentioned that I'd spoken to Jean a while back, and told her you had a bit of a personal problem?"

"Yes," I replied.

"Well, I did say to her it was something to do with your privates, and that I had been told by a doctor that I had to help you to cum."

I was a little shocked mom had told aunt Jean about this, who I knew as equally as 'prim and proper' as mom (before I knew about mom's own lustful nature, that is).

"What did she say?" I said, a little alarmed.

"She was quite surprised, and at first didn't approve. But I told her it was for medical reasons, and for a few weeks only, and we had no choice. But I haven't told her just how far I've gone with you. She has no idea yet."

"Yet?" I replied. "I can't ever imagine getting to the stage of telling her what we're doing or Jean letting me ever have sex wit her," I added.

"I know what you mean Jacob, but I also know my sister very well unlike you, and I know her intimate ways in the past. She used to be quite friendly with men in her younger days before she got married. She changed a bit after getting married and becoming a widow, but she's been single now for a while, I know she hasn't had sex with a man for over two years."

"So?" I said.

"Well, I know she has sexual urges and cravings like all women, and she's confided those to me. My plan is that we should ask her to stay with us for a few weeks and we'll try to get her involved in some way in helping you. You know she doesn't work like me, so she will have the time."

I remembered Aunt Jean was fairly well-to-do, as she lived off a large insurance payout when her husband died

"We won't tell her to start off with that Dr Taylor has now said we don't need to take samples of your cum anymore at home, or the new suggested treatment," mom continued. "We'll start off by keeping quiet about that. We'll use the excuse that while I'm at work, you need someone to help you cum. I think that when she starts to see your lovely cock and body, her lustful cravings will develop into something more, just like they did for me. And I will try to encourage and entice her and ask her to join me when I do a pretend collection of your cum. I'm sure we'll be able to get her begging for you to fuck her by the time we've finished!"Wow! I was amazed by the way mom's mind worked. Fuck me! I was trying to imagine both mom and aunt Jean playing with my dick at the same time to help me to cum. Man!

"Ok," I said. "I won't complain about having two women play with my dick," I added with a giggle. "And it's kind of exciting that it's you and aunt Jean at the same time."

"Your aunt's got a nice large butt as well, which I know you like," said mom, smiling back at me teasingly. "Just imagine having two full juicy ass's to play with."

My dick stirred at the thought, even though I had cum just moments ago. To be honest, I had been turned on by aunt Jean's ass many a time when she had been over to stay before. It was quite full and curvy, very much like mom's, but maybe slightly bigger, although not gross. I decided not to mention I had fantasised about aunt Jean to mom just yet.

"Mom you're mind is just amazing," I replied, keeping my thoughts to myself.

"I haven't finished yet," said mom. "While Jean's here, we'll also start having sessions with Dr Taylor where we get the doctor to think she has helped us to have intercourse together for the first time. I've got the feeling Dr Taylor can be a lot more hands on then she let on to us so far, if you know what I mean."

My dick stirred again, and I just looked at mom open mouthed!As I regained my composure, mom got up off the bed and started to walk over to her mirrored wardrobe.

I loved watching her walk about in the nude. Her tits wobbled from side to side, as did her glorious full buttocks, the juicy, ample flesh on them jiggling up and down, and from side to side as she did so.

She bent her face towards the mirrored front of the wardrobe and plucked something out of the corner of one eye with a finger, and looked at her reflection. Fuck, her full, curvy ass looked so damned sexy, angled to one side, as she stood there naked with her back to me!

"Let's get something to eat," she said, as she looked at her reflection.

"Ok," I replied. I was feeling hungry too.

"Tell you what," she said, "You get dressed and go down, and I'll be there in a few minutes, after I think of something to put on."

"You don't have to," I said cheekily, as I walked passed her to the door.

She gave me a friendly slap on one butt cheek as I passed her, and said with a giggle, "Dirty boy."

I went to my room, and put on a t-shirt, boxer shorts and jeans, and then went downstairs to the kitchen. I poured myself a glass of coke from the fridge and sat down at the kitchen table, waiting for mom to come down. I sipped on my drink, and wondered what she would wear, smiling to myself at my joke earlier in the bedroom.

Then, I remembered the envelope Dr. Taylor had given us. I had l left it on the small table next to the front door. I got up quickly, and hurriedly walked into the hallway to retrieve it.

Grabbing the envelope, I went back into the kitchen table and sat down again. I was just about to slip my finger under the seal of the envelope, when I heard mom's footsteps at the top of the stairs. I decided to hold my curiosity in check, and open it in her presence, just in case she became a bit annoyed I didn't open it in front of her.

Soon, she came in and I was a little surprised to see she was just wearing a white, full-length bathrobe. Maybe she had decided to listen to my request after all, as I wondered if she had anything on underneath!

"I've got the envelope the doctor gave us," I said keenly, as she walked in.

"Let's eat first," she replied. "That can wait a bit. Omelette ok?"

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

As we eat, we talked small talk about how my studies were going at college. I think mom intentionally kept off the subject of what the doctor had said, and I decided not to bring it up. It was kind of funny how mom just 'switched off' the sexual part of what we did together. But it kind of turned me on too, as she sat there at the kitchen table, and talked just like any middle aged mother might have done to her son, knowing just how slutty she could be too, when her lust took over.

After we finished eating mom said, "Bring the envelope in the living room. We'll open it there and discuss things further. Oh, and do the washing up for me, honey."

Mom got up to go to the living room whilst I did my chores.

My anticipation was high as I rinsed the dishes, going a bit quicker than normal. I wanted to see what the doctor had written!

After drying my hands, I picked up the envelope and walked quickly into the living room.

Mom was sitting on the one end of the cream coloured three seater sofa, still fully covered up in her bathrobe.

"Come and sit next to me honey," she said.

I liked the way she had recently started to call me 'honey'.

I sat down, still holding the envelope.

"Open it up, and hold it between us so we can both read it at the same time," she said.

I almost ripped it open, and took a single sheet of white A4 sized paper out. I unfolded it and held it between mom and myself so we could read it together.

Here is what it said:

'Jacob, here are some details of some women you can see. I have given some of their sexual preferences so you can choose. They have given me permission to give these details out to any males I consider suitable for sexual meetings based on the needs of both parties. Please keep this information confidential.

Clarissa: Aged 52. Likes young men aged under 25. Widow with very high sex drive. Particularly likes oral sex. Enjoys naturism, nudity and exhibitionism. Bisexual. Holds a highly respectable position in her community, member of various committees, and so requires absolute discretion.

Beth: Aged 49. Good natured and very accommodating to nervous types/first timers. Divorced, but well off, likes being serviced regularly by younger men. Has a particular fetish for dressing in uniforms and anal sex.

Deborah: 54. Married with older husband who has limited ability to perform. Likes to have sex with virile younger men in front of her husband. Husband approves and may join in if aroused.

Patty: Aged 53. Married to older husband who is away much of the time on business. Bisexual. Likes role-play of various sorts and sex with more than one man/woman at a time. Fetish for double penetration (DP) and well endowed black men. Husband unaware, so discretion required.

Bernice: Black lady aged 52. Very high sex drive. Enjoys interracial sex and multiple men/women. DP, a favourite. Highly respected member of her local gospel choir/church. Requires absolute discretion.'

As I read the note, my dick had started to get hard. The further I read, the harder it seemed to get, until it was straining against the material of my jeans.

At the end of the note were telephone numbers of the women and a footnote in brackets saying 'Any individuals these ladies see are only those referred directly by me as their doctor and sexual counsellor, and only after screening for STDs to ensure the health of all concerned'.

I was kind of agog after reading all this. I looked up at mom who had also just reached the end of the page. She also looked a little taken a back and her cheeks had flushed red, but she also had a sort of worldly-wise look on her face.

"Very interesting," she said after a moment, breaking the silence.

I didn't know quite how to respond. I did know I had a hard on, but I'd kind of covered it with the sheet of paper so I wasn't sure if mom had it noticed yet.

"Do you think you'd really like to see any of these ladies?" asked mom enquiringly. I think she also had a bit of a disapproving face on her as she spoke, but I couldn't be sure.

"Well....er.... I...," I spluttered hesitatingly, still not sure whether to sound keen or not.

"Go on, be honest with me Jacob," she continued, in a confrontational sort of tone, this time.

"Well...er...mom...er...one or two of them sound a bit scary, but I...er... I mean...reading about them has got me a bit excited, so I guess....I...I would like to meet one or two," I finally blurted out. Actually, I think I might have liked to see all of them, but I didn't want to say that just yet to mom. They all sounded incredibly hot women!

Mom's face seemed to ease a little and she relaxed a bit. Perhaps she had just been waiting for me to confess what I actually felt.

"I see," she said. "Well, I have been around a lot longer than you Jacob, and I do know how women can be behind closed doors, so none of this really surprises me. Some of them sound like they have quite respectable positions in life, covering very lustful natures. A bit like me perhaps. To be honest Jacob, reading this has made me a little flustered too."

With that, mom moved her hand over my crotch and felt my bulge.

I felt a little relief at mom's reaction to the doctor's note, and my hard on responded to mom's encouragement and touch.

"I can see this has got you going," she said smiling a little now, and rubbing her fingers over my hard cock through my jeans. She licked her lips.

"Let's put this note from the doctor away for a while and give you some more of the doctor's medicine," she continued. "Get that juicy, hard dick out."

That was music to my ears.

Hurriedly, and feeling quite aroused, I laid the sheet of paper on the coffee table and got up. My dick was bursting to get free.

Mom straightened herself up on the sofa, moving a little closer towards the edge of the cushion, whilst I stood in front of her and unzipped my jeans.

I yanked them and my boxer's down in one go, and stepped out of them, kicking them to one side so they were well out of the way.

My hard cock sprung up towards mom's face, and she immediately engulfed the tip into her warm wet mouth.

"Ahhhh," I groaned with pleasure, as she took it in.

I stood there just in my t-shirt, naked from the waist down and watched as mom sucked on my dick. It was a fabulous sight and feeling. She still had her bathrobe on and was fully covered, but for the moment I didn't care, as the feeling of her sucking on me was ecstatic.

"Yea, mom," I said, "Suck on it. Suck it hard."

I grabbed her head with my hands, encouraging her movements in and out, as she took more and more of my cock in her mouth with every suck.

She was really going for it, making slurping and gurgling noises as she sucked me.

As she sucked on me, my mind wandered back to those women the doctor had described and what they liked sexually. The thought of them willingly being available for me to fuck, mom agreeing to this, and the dirtiness of their sexual desires behind a facade of respectability turned me on incredibly, and I just felt like cumming in an instant in mom's mouth. I didn't feel I could hold back.

"Mom, I think I'm gonna cum really quickly this time," I said.

Mom didn't respond except by clamping onto my dick even harder with her mouth and cupping my balls from below with one hand, almost encouraging me to spurt in her.

After few more moments of this I came, "Auhhh...Ahhh.....UUUUHhhhhhh," I shouted out, as I spurted wave after wave of thick, gooey cum into mom's willing, waiting mouth. She tried to take in as much as she could, but I must have cum so much, that some of it started to come out of the corners of her lips, and then she just opened her mouth as if she couldn't swallow any more, and even more poured out and onto her robe, and some even went on the carpet!

"Oh, fuck mom," I said. "That was so good. It was thinking about those women that made me cum so much and so quick."

Mom looked up and me and smiled a cum filled smile, and then started to lick my dick clean, paying particular attention to the tip by sucking any cum left in and around it. She even scooped up some of my cum which had fallen on her robe with two fingers sand placed them in her mouth. Fuck!

After a moment she said, "I love your thick, creamy spunk you dirty boy. I know you like the thought of those dirty women too. They are real sluts aren't they?"

I just nodded, a bit taken aback at mom's dirty language so soon after my cumming. She must have been really turned on too!

Then she said, "But we need to fuck. You've cum in my mouth, which is fine. But the doctor said we must have penetrative sex. And my pussy needs some attention too. Do you think you'll be ready again soon?"

"I'm sure I will mom" I replied. "I'm still feeling quite excited about the thought of fucking those ladies."

"As long as you keep enough of your spunk for me, I'll let you," she replied smiling, and firing up my lust yet again, with her reaction.

"But before we do anything else," she continued, "Go and get some large towels so we can spread them out on the sofa and carpet as we don't want to get them messed up. Some of your cum went on the carpet this time, you came so much. Oh, and take off your t-shirt. I'd prefer you completely naked now."

I pulled off my t-shirt and chucked it on the single sofa chair in the corner. Naked, I walked out of the living room and ran upstairs, my now limp dick and balls swinging freely as I did so.

I the bathroom I gave my cock and balls a quick rinse and picked up a couple of large towels before going back down.

I was met with a wonderful sight as I came back into the living room.

Mom had taken off her bathrobe and had laid it over the cushions of the sofa (to protect tem from our activities it seemed) and she laid her back against one end of the sofa with her legs wide open, fingering her pussy.

"Come and lick me, " she said firmly, "My pussy needs attention."

I laid the towels on the carpet in front of the sofa and knelt down on them in front of her, spreading her thighs wider, I started lapping and licking at the mounds of her beautiful, moist cunt.

I stroked my tongue up and down the outside of her pussy lips as if teasing her, and then darted it in deep.

"Ohhhh....Ahhhhh," she moaned, with pleasure. "Keep on doing that," she added.

I continued with my face buried in her slit, and I raised my arms and started to squeeze and fondle her ample boobs.

It was a glorious feeling. My tongue and hands were on a sensation high!

My dick hadn't quite yet started to respond as it was so soon after cumming earlier, but I was happy to continue giving mom some much needed relief.

As I continued my licking and lapping at mom's wonderful, moist pussy, she ground her hips up into my face and started thrusting it up harder as I pushed in with my tongue. This continued for a few moments, getting more and more intense, when finally, she cried out, "Ohhh...Ohhh....Ahhhh....yes," and her hips bucked up and down and she shook several times, almost involuntarily, then fell back against the sofa cushion. I guessed she had just orgasmed.

I continued licking her pussy, and fondling her tits for a moment until she spoke.

"Thank you darling. That was wonderful, and just what I needed."

"Did you orgasm?" I asked.

"Yes," she replied.

I smiled and felt pleased I had been able to give her some relief.

"Bring the doctor's note and sit next to me again," said mom, now sitting up again and patting the sofa cushion next to her. "I'd like to read about those women again, and maybe we can choose someone for you to see first."

My ears pricked up and I immediately got up of the floor.

Picking up the doctor's note again from the coffee table, I flopped down next to mom. We were both naked next to each other now, and I was sure it would not be long before my dick would be buried deep in mom's pussy, as we talked over the lusty women the doctor had chosen for me.On reading the doctor's note again mom had second thoughts about me going to see other women just yet.

"I'm really not sure Jacob," she had said, "About you seeing all these women yet. They all sound very experienced and you're not. Maybe we should wait a bit longer and see how we can get along between the doctor and us, and maybe your aunt Jean might agree to help."

I didn't have a problem with that, and in my easy going way I just nodded and said "Ok, mom." I was no fool and knew I was onto a good thing here, getting mom's pussy and ass as I wanted. Anything else was just a bonus!

Mom & I continued our fucking session regularly over the next few days, and I just couldn't get enough of her glorious full backside which she let me fondle and play with to my heart's delight anytime I wanted!

One evening not long after we had read the doctor's note, she said "I'll ring Dr Taylor and see if we get another session with her as it was such a turn on for us both last time. Let's get her thinking she will introduce us to intercourse." I liked the way mom used the word 'intercourse' instead of 'fucking'.

After returning from college the next day, mom described the conversation she had with the doctor on the phone.

Dr Taylor had been quite pleased to hear that mom was willing to 'take things further,' which of course, meant mom was agreeable to the doctors suggestion to let me penetrate mom as part of my treatment. The doctor obviously did not know we were already well past that.

"When we see the doctor, you must play completely innocent, Jacob," mom said, as she broke off re-telling of her phone conversation with the doctor. I nodded my head.

Mom continued, "Dr Taylor also asked me if I owned any suitable underwear, and to bring it along at the session, as she thought it may help in stimulating you." I smiled hearing this. "Of course I knew what the she meant," continued mom, "But I played a little innocent saying 'you mean something sexy?'"

"Yes", replied the doctor.

"I'll see what I can do -- would black stockings, bra and panties do?"

"That sounds just fine Marge," said the doctor. They then confirmed the time and both said they would look forward to seeing each other and hung up.

The session had been set for the next day at 4.30 pm. Mom said she would leave work a little early, go home to shower and change and then pick me up from college at 4 o'clock.

Hearing mom describe the call with the doctor had an immediate effect on me, and my cock was soon buried inside mom's eager and willing pussy as she bent over the kitchen table. Without much ceremony, I had lifted her skirt and yanked her panties to one side before burying my cock deep in her. I thrust in and out as she slapped her big fleshy butt back against my balls and groin. I swore as we fucked and called her a dirty bitch, amongst other things. It was an enjoyable part of our fucking now, swearing and using dirty language, which she liked and encouraged me to use, and she responded in turn, which spurred me on further, until I spurted inside her.

During the next day at college I had a semi hard on thinking about what we might all end up doing in the doctor's office later in the afternoon.

Mom picked me up on the dot at four. She looked nice with her hair done and make up. She was wearing a business suit with a skirt that was just below knee length. She looked like she'd come from work, but I knew she had been home first. I kissed her on the cheek as I fastened my seatbelt. As we drove off, I let my hand wander down over her thigh and under the hem of her skirt to her stockings over her knee. I stroked my hand upwards over the silky material, exposing the tops of her stockings and naked thigh, and briefly stroked the exposed skin there.

"Now, now tiger," mom said, smiling, without taking her eyes off the road. "Be patient, you'll see a lot more of me very soon. Just make sure you're nice and hard for momma," and she licked her lips, letting her tongue linger outside them momentarily.

Fuck, what a tease! I was hard in my pants. I chuckled in response and looked at the road in front, hitting the window wind-down button on my door side as I did so. The wind blew back my hair and cooled down my face and lust, somewhat. I was looking forward to the rest of the afternoon and evening.

We were let in by the same mid-thirties looking blonde as last time. She welcomed us with a smile and ushered us in. She wore a tight fitting white nurse type outfit, which had quite a low cut top. The tops of her tits were clearly visible like last time, and my dick responded with a twitch at seeing them again. I followed directly behind her as she walked in front of mom and I, watching her ass sway sexily. Fuck, she was hot! There were no other patients in the waiting room, and the receptionist led us straight to the doctors consulting room, knocking loudly on the door as she did so.

Dr Taylor stood up from behind her desk and welcomed us with a broad smile. She told the receptionist, whose name was Cynthia, she could go home early, just like last time.

The doctor wore a white coat, but it was unbuttoned at the front, and I noticed she was wearing a black skirt and dark brown v-neck sweater underneath which showed off an ample cleavage.

"Marge, Jacob, how very good to see you again," she said beaming at both of us.

Mom and I reciprocated with smiles that contained an edge of cheekiness, as we were about to lead the good doctor on with some pretence in connection with our sexual activities so far.

The doctor led us straight into her inner consulting area and I looked around remembering it as before - it had a much more cosy and informal feel to it compared to the doctor's main consulting room. It was more homely and even intimate. There were matching lampshades, a luxurious beige carpet with a large roomy black leather sofa and a separate matching sofa chair. At one end of the room a very comfortable looking milky chocolate coloured leather bound couch/examination table was placed in the centre space so you could walk around it, where I guessed people could lie down. There was also a door to another room, which I remembered was the rather nice shower/bathroom.

"I have no other patients today, so we can relax and take our time," said Dr Taylor. "Please do sit down."

Mom and I sat down next to each other on the large black leather sofa.

"May I offer you a glass of red wine?" said Dr Taylor moving towards a drinks cabinet. "I often have a glass after work to relax."

Mom and I both said, "Yes," almost in unison.

The doctor brought over two full glasses and placed them on the low coffee table in front of the sofa.

She then took a glass for herself and sat down opposite us. She had removed her white coat before returning to the sofa.

She crossed her legs, showing us her black stockings and low-heeled shoes.

"So how have you been getting on since we last met?" asked Dr Taylor keenly.

Mom answered first, "Well we've been collecting samples as before, but I've had a think about what you said last time, and I think I'm ready to go to the next stage of the treatment you recommended doctor."

"Good," replied Dr Taylor. "I take it you are both agreeable to penetration, for medical reasons, of course?" she asked directly.

Mom and I both nodded.

"It is rather unusual doctor, and I do feel little awkward about it," mom added, "But if, as you say, it is required to resolve the problem Jacob has, then I am willing to act as a 'body donor' so to speak. I am a little hesitant, but I hope you will be able to help us perform the act so we are both able to deal with it in an adult way." Mom spoke very convincingly, although it was a pretence.

"Yes, of course," replied Dr Taylor. "I do understand your hesitancy, Marge. But do take it from me that penetrative sex is what Jacob requires in order to balance the bacteria present in his body, and it will lead him to be completely normal in due course. This whole matter will remain entirely confidential between us, so you need not worry in that sense, as no one else will know."

"Oh, that is a relief," replied mom, continuing her 'act'.

"And what did you think of the note I gave you last time?" continued the doctor. "I believe, I mentioned Jacob would benefit from mixing of his genital fluids with a wide range of women, such as the ones I suggested, who are clients of mine and also very discreet."

"Well, doctor, replied mom hesitatingly, "I did think it over, and for now I'm not so comfortable with him seeing anyone else. Perhaps in a few weeks, but I just can't bear the idea of him going with some strange women yet."

"I see," said Dr Taylor, looking slightly disappointed. "I do understand."

"But," continued mom, I do have a sister, Jean, who I may be able to persuade to help us."

The doctor's eyes lit up momentarily. "Oh yes?" replied the doctor, "Do tell me more about Jean."

"Well Jean is now a widow and lives on the west coast. She is a couple of years younger than me and I may be able to persuade her to help us, perhaps with some support from you. My sister is a very straightforward lady, who might like to help if the recommendations came from someone in authority and held in professional esteem, such as yourself.

"I see," said Dr Taylor. "Well I'm sure I could give you a letter to send her, explaining the medical reasoning of the treatment required for Jacob, or perhaps you could, bring her to see me, whichever suits you best.

"Thank you doctor. I will let you know," replied mom with a smile.

All three of us had been taking sips of the wine as we sat and talked and I was feeling quite relaxed due to it. I was sure it was having a similar effect on Dr Taylor and mom.

"Jacob, you've been a bit quiet, so far," said Dr Taylor.

I smiled a response "Oh just happy to listen," I said. "I'm just pleased everyone is so keen to help me," I added truthfully.

The doctor beamed a smile back at me.

"Well, now," she replied, "Perhaps we should make a start. The purpose of this session is to help you and your mom to begin the process of penetrative sex so that by allowing the genital fluids to mix, your medical condition is treated. I hope that by helping you both to break the 'barrier' so to speak, here in my presence, you will be able to continue the treatment at home. Is that understood?"

Mom and I both nodded in agreement.

"Whatever I suggest you do," continued the doctor, "Please try to act as naturally as possible during the sex act and leading up to it. I am also going to suggest some foreplay so as it get you both best aroused, and as the facilitator to the treatment, I will give you instructions and may participate to a certain degree. Are you both happy to follow my instructions and for me to participate in the treatment as I see fit? This may involve certain mutual touching and verbal encouragement, which normally occurs during sex."

"Yes, that will be fine," said mom

I nodded, and felt my dick twitching in anticipation.

"Also, I think it would be appropriate to use normal everyday words which men and women use for our body parts and the act of sex, which may be considered rude in the wrong context, but for our purposes the context is entirely appropriate and suitable. Are you both happy with this?"

Again, mom and I both nodded. This sounded like it couldn't get any better!

"Good. I am so pleased we are all happy with this arrangement, which you must remember is purely for medical reasons," said the good doctor.

"Now, Jacob, I want you to go into the bathroom, take a quick shower and then come out wearing the white bathrobe I've left in there for you. There are plenty of towels, so just help yourself."

I remembered how clean the doctor liked everything to be, so I happily got up to, oblige, leaving mom and the doctor to continue drinking their wine and I assume, decide what would happen when I emerged from the bathroom!

Entering the bathroom, I noticed how luxurious it was. There were very fancy looking tiles on the floor and walls, a walk in shower with multiple shower jets and curved clear glass sides which looked big enough for at least 3 people, a large jacuzzi style bath as well as a toilet and bidet. There were plenty of fresh white towels on a warmed towel rail and a couple of white bathrobes made of towelling fabric hanging on two hooks behind the door. This was certainly not the type of bathroom I expected to find in a doctors surgery, but it was great nonetheless!

I took my clothes off and placed them neatly on a cabinet, and entered the walk in shower. The multiple power shower sprays hit my body from different angles, and were intense and invigorating, and I cleaned myself all over in no time, paying special attention to my dick, balls and ass crack.

I towelled myself down. My dick was feeling a little 'filled' in anticipation, making it look longer whilst hanging down, but is wasn't quite erect. I gave it a quick feel and stroke to try and relax it, and then pulled on the white bathrobe.

As I entered the inner consulting room again, was met with a most delicious sight. Both ladies had their backs to me, and turned around as they heard me come into the room, but not before I had a chance to look at them momentarily 'from the rear', so to speak

Mom had taken off her clothes and was wearing just a black half cup lacy bra with her boobs almost hanging out, black mid-sized lacy panties which clanged to and emphasised her large butt wonderfully, black stockings and black stilettos. Fuck she looked hot!

The doctor too had taken off her clothes and was also in black bra, panties and stockings, although not quite as sexy as mom's. This was the first look I had of the doctor without any clothes and although she was much stockier in build than mom and so a bit less shapely, her large ample boobs looked gloriously suckable, and her big wide panty-wrapped butt looked enticing.

"Wow, you guys look good," I said, as I entered the room.

"Thank you dear," said mom. "The doctor had suggested I try to dress up suitably to try to stimulate you, and I think the wine has taken away my shyness."

"I also thought it best to try to contribute and help the stimulation," said Dr Taylor smiling, and I know you like 'bottoms' from what your mother has told me, so I did not think it amiss to go down to my underwear as part of this session.

"That's fine doctor," I said, "I do appreciate your attention to detail towards my needs."

"Now," said the doctor, I would like to try the first penetration, in a position such that you do not need to look at each other, which may make it easier to perform - the doggie position. Marge I would like you to kneel on the sofa with your hands holding the top edge of the sofa, and your bottom sticking outwards toward the coffee table. I think this will also help get Jacob stimulated and hard.

Mom walked over to the three-seater leather sofa and positioned herself as instructed. Fuck she looked damned hot with her white skin contrasting the black lingerie and black leather in the background!

The doctor dragged the coffee table out of the way and walked me over so I stood a couple of feet behind mom's ass which was sticking out towards the edge of the sofa seat with the doctor standing next to me.

"How do you like the sight of your mom's ass in that position Jacob?" said Dr Taylor.

"It looks very arousing," I said. My dick was tenting up my robe at the front.

"Are you comfortable Marge" continued the doctor.

"Yes, very," replied mom.

The doctor undid the belt on my robe so the front fell open and my dick shot out semi hard.

"Ah good," said the doctor. "I see you are stimulated." The doctor wrapped one hand around my shaft and started wanking my dick to get it harder. Then after a minute or so of doing this she pulled off my bathrobe completely, and threw it on into one corner, leaving me totally naked. My dick was semi erect with mom still positioned doggie fashion on the sofa a couple of feet in front of me.

"That's better," said the doctor. "Now you can proceed more naturally." She looked quite pleased at my nakedness, and I was secretly getting quite a kick out of being like that in front of her, with mom so sexily positioned just a few feet away.

The doctor then with her right hand gave my balls a brief cup and squeeze and started to pump my dick again, and with her left hand she started to caress and grope my ass cheeks. Fuck! It looked like she was getting some pleasure out of feeling me up now! I realised mom had been right in suggesting the good doctor was a lot more 'hands on' than we had originally thought!

After another minute or so of the doctor feeling up my dick, balls and ass, she said, "Now Jacob, I am going remove your mother's panties and you may play with her ass a little."

The doctor moved over to mom and slipped off her black lacy panties, sliding them down her hips, knees and legs and then off over her feet, as mom positioned herself to ease the process.

I now had mom's beautiful large, fleshy ass cheeks in front of me. I had seen them like this before of course, but the doctor did not know this, as the whole aim of this session was to get the doctor thinking she was the one to introduce us to fucking proper, and join in with us.

"Go on, play with your mom's ass cheeks," said the doctor encouragingly.

I moved so I stood directly behind mom's ass as she knelt, with my dick still half erect and gave mom's ass a good grope and feel.

"Does that feel nice?" asked Dr Taylor.

"Oh yes doctor," I replied. "It feels fabulous."

"And you Marge, do you like it?"

"Well, yes, I guess so. It does feel rather nice, although a little strange knowing Jacob is doing it," said mom, play-acting a bit."

"You'll get used to it and more," replied the doctor. "Now Jacob, I want you to kneel down and kiss and lick your mom's ass as I pull open her butt cheeks."

The doctor stood next to mom, slightly to one side, and gently prized open mom's fleshy ass cheeks so that I could see her pussy and asshole clearly.

Needing no more encouragement, I knelt down as instructed and kissed the fleshy part of moms ass cheeks the doctor hands were not on.

"Lick mom's pussy as well," instructed the doctor. "It is all part of the foreplay."

I lapped at mom's pussy for a while licking her labia lips and the pink flesh inside her cunt.

"Now, lick your mom's asshole."

Fuck, this doctor was hot and dirty! My dick was now rock hard as I moved my tongue around mom's rosebud. This was one of my favourite things to do with mom! I just loved rimming! I let my tongue go deeper into mom's asshole as she squirmed in delight as I did so. The whole thing was incredibly hot and horny, especially as Dr Taylor held open mom's ass cheeks as wide as she could with her hands and encouraged me.

"Now lick from asshole to pussy and then pussy to asshole, and back again."

Fuck!

I did as instructed as I darted my tongue in and out of mom's asshole and then down to her pussy, darting it in and out and licking around, and then back to her asshole again, and then in reverse.

My dick was now raging hard and pulsating up and down.

The doctor must have sensed or seen this as she then said, "Now, Jacob, ease your prick into mom's pussy."

I stood up and adjusted myself to the right height by bending my knees slightly.

The good doctor still held mom's ass cheeks open for me with her hands as I brought my cock head to the opening of her cunt.

I plunged in, in one stroke I was so desperate. Mom gasped. The doctor said, "Steady now son, not too fast." I pulled back letting mom's muscular pussy walls claim their grip on my dick. Then I thrust in again and pushed forward."That's right Jacob. In and out, not too fast and not too slow, just do what comes naturally," continued the doctor encouragingly.

I continued pistoning mom's cunt and it felt glorious. The doctor let go of holding mom's ass cheeks open as I was now well and truly in and she instead kept one hand on my ass as I thrust forwards and backwards. It kind of felt strange and nice at the same time!

The idea that I was now fucking mom in front of the doctor was really turning me on, and I was sure mom was feeling the same, although she did not let on. Her face was buried in the top edge of the sofa and her arms were partly over the sides of her face so we could not see her expression, but she let out some groans of pleasure as I continued to pump her.

"That's right Jacob, fuck your mom, stick your hard dirty cock into her juicy cunt and let all those lovely juices mix and make you better," uttered the doctor.

I continued my thrusts and then noticed the doctor had removed her hand from feeling my ass as I pumped and saw she was unclasping her bra. Fuck!

As her bra came off, I saw the doctor's large pendulous boobs from the corner of my eye as she stood next to me, and again started pushing and feeling my ass cheeks as I thrust into mom.

The doctor's tits wobbled and jiggled roughly and I noticed two large pinky-brown areoles and nipples, as I looked sideways momentarily.

"Go on fuck her hard Jacob and watch my titties at the same time." Fuck this was amazing.

The doctors tits and dirty encouraging words were fuel o my raging fire of lust now, and I increased the pace of my thrusts and even slapped month ass cheeks a few times as I gripped her love handles.

Then, incredibly the doctor left my side and shot around to the back of the sofa so she was now facing me, and placed her hands on the top of the sofa near where mom's hands were. She then bent forward ever so slightly and started moving herself from side to side so that her tit's hung down and wobbled and jiggled sideways as she did so. Mom's head was still buried in the sofa so she could not see this, but it was an incredible sight!

As I continued pumping mom, the sight of Dr Taylor's pendulous, melon like boobs jiggling and wobbling and hanging down almost like udders as she swung them, pushed me over the edge.

I knew I would not last much longer now as and after just a few more thrusts I blew my load deep into mom's pussy with a loud "Ahhhhhh.....," as I did so, followed by several grunts as I spewed inside her, each groan timing with a spurt of my cum.

Mom also groaned loudly as I came, indicating she must have at least orgasmed too.

I became light-headed and I closed my eyes, still holding onto mom's hips as the last of my cum waves eased and my dick became limp. Fuck, that had felt so good....."I regained my composure and opened my eyes. Mom was now sitting on the sofa trying not to look too much like she had enjoyed being fucked by me. The good doctor was standing next to me with her left arm clasped around my waist, holding me slightly towards her so our bodies touched, as we stood in front of mom. She was beaming all over like the cat that had got the cream! She was still topless, her ample boobs hanging glaringly on her chest, and still in her black panties and stockings.

"Congratulations," she said out loud. "Well done both of you, and especially you, Jacob, as you're no longer a virgin."

I smiled back at her, knowing my secret, fully aware that I'd lost my virginity to mom some time ago, and trying not to ogle at her boobs too much, particularly as her left tit, which was nearest to me, was squashing up against my body. Fuck!

Mom continued play-acting with the doctor a little by saying hesitatingly, "I hope that was ok Dr Taylor. I mean, I did do my best for Jacob for medical reasons."

"Yes, yes, my dear Marge, you did very well. I hope it was not too difficult the first time for you with Jacob, as it is a bit of a taboo to do it with your son. But remember, it is all for the best of medical reasons, and what mother would not want to do the best for her son now?"

Mom looked reassured and smiled, happy the doctor did not seem to suspect anything was amiss, and that she genuinely thought it had been the first time for her and Jacob. She had got quite turned on by the whole thing, but luckily had been able to hide the pleasure on her face from the doctor and muffle her groans and dirty talk she normally liked to verbalise.

"I hope you are both happy with my involvement as facilitator," continued Dr Taylor.

Mom nodded politely and smiled. She had been particularly pleased the doctor had held her ass cheeks open and voluntarily taken her bra off, as that indicated the doctor might go a lot further, although she did not openly want to seem too keen at that. Cheekily, but very innocently she said, "Thank you for holding my bottom and assisting Jacob. It did make the process easier, feeling your hands on me in support. And thank you for removing your bra. I'm sure the sight of your very nice breasts did help to stimulate Jacob further."

For some reason, I thought I detected a slight blush on the doctor's cheeks, but I could not be sure. My eyes moved back down to her boobs, which I was now dying to caress and suck, particularly as one of them was squashing sexily into my chest.

I thought I should add a compliment and said, "Oh yes, Dr Taylor, may I say how wonderfully arousing your breasts are. I hope you do not mind me saying so."

"Of course not Jacob. As a young man, it is natural you should be attracted to them. It is quite normal. In fact, I may let you touch them in due course as part of my role as facilitator."

My dick twitched in response at the thought, even though I had cum just a moment ago.

I doctor just happened to be looking down at that moment, and saw my dick getting aroused momentarily.

"Ahh...a twitch of agreement from your cock I see," said the doctor, and mom and her both laughed out loud.

The ice, if there had been any, seemed well and truly broken.

Still with one arm around my waist, and her left boob still squashing up against my chest, the doctor gave my limp cock and balls a feel and caress with her free hand. "What a wonderful cock your son has Marge. You should be very proud."

Mom smiled back, but didn't say anything, perhaps not knowing quite how to respond. The doctor then lifted my limp cock in her hand and rubbed over the tip. Some cum was still on the end, and she massaged it into my cock and balls, again giving my privates a good feel all over. Fuck, she was giving me a good grope!

Finally letting my cock go free and rubbing my chest instead she said, "Now perhaps we should get cleaned up a little before we have another go -- do you think you will be ready again soon Jacob?" Her hand became stationary on my chest for a moment.

"Oh yes ma'am," I replied.

"Definitely," confirmed mom, "He can cum quite a few times in a few hours. I know from experience in collecting his cum!"

"Excellent," replied the doctor. "Let's freshen up first and then we'll continue the treatment."

"I'd like to use the toilet for a moment," I said, feeling the need to pee after cumming.

"I need to clean myself and use the toilet as well," said mom.

The doctor's eyes seem to light up with a thought.

"As, facilitator, I would like to suggest we all go into the bathroom together," said Dr Taylor. "The reason being, as we do such personal things in the bathroom, by sharing what we do in there, will help break down any psychological barriers. We must not have any secrets between us."

There was a bit of a silence hearing the doctor's suggestion as it sunk in.

Mom looked slightly perturbed. I thought it was just another kinky side to the doctor. As I had seen mom pee once before and enjoyed it, it was a quite exciting thought to be able to watch her again, although I didn't let on.

Mom regained her composure and said finally, "Well, if Jacob is fine with the idea, perhaps we should follow your suggestion."

"Ok by me," I replied, trying to sound as innocent as possible.

"Marvellous," said Dr Taylor. "Follow me."

The doctor, still topless started walking towards the bathroom door, her glorious fat butt cheeks bouncing up and down in her black panties as she did so. Fuck! I loved watching a large womanly ass move!

Mom followed behind me. She still had her bra and stockings on, but was panty-less.

The doctor entered the bathroom and held the door open for us.

When we were all in, she closed the door. Mom looked around. It was her first time in the doctor's luxurious bathroom.

"My, what a fabulous bathroom you have," said mom gazing around at it all. "And how spacious!"

"Yes," smiled the doctor. "I do like to have some counselling sessions in here of various kinds, and it needs to be spacious and comfy."

I didn't let my mind dwell too much on what kind of counselling sessions the doctor might have meant, but I was sort of getting the gist from her actions so far.

"Now, Jacob, ladies first. Let your mom have a pee. Don't be shy at doing it in front of your son and I, Marge. Remember, no secrets between us -- you must feel it is completely natural to do it in front of us."

Mom seemed to hesitate, I believe genuinely this time. But then she walked over to the toilet and sat on it.

After a moment, a clear stream of urine could be heard hitting the water in the toilet bowl. I could not see much of the stream, but we could certainly hear it. Mom finished after a minute or so and dabbed herself below with some tissues from a toilet roll next to her, got up and washed her hands in the sink. I had enjoyed watching her, and it triggered some strange feelings in me.

"Good," said Dr Taylor looking pleased. "Now you Jacob."

I was quite desperate to pee now, so my inhibitions in doing it front of the doctor and mom went to one side. I lifted the seat and held my dick so it pointed into the bowl.

The stream came in no time sand I felt a wave of relief as my bladder emptied. I hadn't looked up at mom and the doctor watching me, but I could sense them looking on intently.

"Excellent," said the doctor. "How did you feel doing in front of us?" she said to me firstly.

"Kind of freeing, I guess," I said. "I enjoyed watching mom pee for some reason. I don't know why," I added truthfully.

"Interesting," replied Dr Taylor. "And you Marge?"

"Well, I kind of felt the same as Jacob described. It is kind of freeing." I think mom decided to be discreet, and not say anymore.

"Very interesting," the doctor replied. "Well some people find it sexually arousing - maybe we can explore that another time," she added.

"Now, next, I would suggest Marge and I remove the remainder of our underwear and all three of us have a quick shower together. The shower is big enough and designed to accommodate several people at once. I would encourage you both to have lots of mutual touching in the shower and wash each other, as it will again help to break down barriers against bodily contact you may still have, prior to the act of intercourse."

Man, this doctor was something, I thought. My dick was now starting to log.

I think the doctor noticed.

She ushered us into the shower. As described before, it had curved glass sides, split into three sections, one of which slid across to let someone in. We all went inside in turn. I would say the shower floor area was about one metre in width by two metres in length, and had several jet sprays along one wall and three shower-head sprays equidistant in the ceiling.

Mom and the doctor were now completely naked and I had glanced at the doctor's fleshy fat ass cheeks and pussy bush momentarily, as she had walked in. Fuck, what a sight! I started salivating!

I was now in the middle, sandwiched between two gloriously voluptuous ladies, one of which was my mom! Fuck!

The doctor turned on the water sprays for a minute and we wet ourselves all over. Then, turning the water off, she said, "Now lather each other up quickly - I know you are both pretty clean already."

"I will do your back Jacob, while you do your mom's. And then we can swap."

Mom turned to face one end wall, I turned to face her back and the doctor faced my back. We all grabbed some shower gel from the various containers and started lathering up -- me doing mom's back, the doctor mine, and mom doing a bit of her own front -- tits and pussy.

Man, this was starting to get seriously erotic, and my dick was coming back to life! I felt the doctor rubbing my back and ass all over, and she even inserted her hand between my ass cheeks, doing my crack, as I was doing mom's in a similar fashion, at the same time. What a sight that must have been if anyone had been watching!

Then the doctor asked me to do her. Fuck!

I turned 360 degrees, and with my back to mom started to lather the doctor's shoulders and back. Now I could see her glorious chubby ass properly, as I grabbed a full handful of her ass cheeks, moving my hands down to wash them. Fuck, my dick was now getting hard!

"Do my ass crack," commanded the doctor.

I obliged, delighted she would allow me to do that. I let my soapy hand wedge between the fleshy mounds of her ass. I rubbed my fingers over her asshole and along her pussy briefly so that the lather cleaned her, but I did not let my fingers linger, so as not to seem too keen. Fuck, that was good!

Mom had not been idle whilst I got a good handful of the doctor's body. She had been doing my back and ass again. Boy, I was gonna be really clean after all this!

Then the doctor returned to face me.

She did not look at me direct in the eye, but straight down at my dick, seeing it was now getting hard and sticking out towards her. The veins in my uncut cock-head were clearly showing, and I saw her lick her lips unconsciously.

"I see you are getting stimulated Jacob," she said, as she started lathering up my semi-hard cock.

I sure was, with the doctor's naked flesh and boobs inches from me. Fuck!

Then she said, "I think that's enough soaping up. Let's rinse." The doctor pressed a button and all three of us were hit by powerful sprays of perfectly temperatured, medium hot water.

The doctor then stood sideways on and invited mom and I to help rinse each other off as she patted both our backs.

We complied. My hard on wilted somewhat during the rinsing.

Then, I had a flash of an idea, and said, "Doctor, you do know how much I like ladies bottoms. I wonder if...well...if you could oblige me with some play of your's and mom's together?"

"I don't see why not," replied the doctor, smiling.

"I'm happy to comply with the doctor," said mom, still play acting a little.

"Marge, why don't you and I turn our backs, and let him have a good look and feel of our ample rears, which still provide such a thrill to a young man of his age?" said the doctor, a little teasingly.

My dick raged up again at the suggestion and the doctor and mom both saw.

They then both turned, so as to face away from the glass panels, so that they were standing side by side along the long wall of the shower, hips almost touching, and their arms folded against the wall for support.

Fuck, what a sight from behind!

I looked first at the doctor, who was slightly shorter than mom and more stocky, and only with a slight curve to her waist, and then down at her magnificently thick, large butt cheeks, the curves of which protruded out at least 8 inches at there thickest point in the arch from her thighs. Fucking, sexy ass bitch!

I then looked at mom's lovely body, which was much more familiar to me, and appreciated how much more curvy mom was, with a 'smaller' and more shapely butt, but still large and ample to behold.

Seeing two naked women with large, thick butts, side by side, just waiting for me to grope and play with them was fucking awesome, and my dick jerked up again to maximum stiffness at the sight.

I decided to push my luck a bit and said rather meekly, "Er...would you both consider wriggling your lovely bottoms form side to side for me, please?"

Without saying anything, the doctor and mom both complied. Fuck what a sight! A wicked thrill of lust went through me, seeing those glorious buttocks wriggle from side to side, the flesh on each rippling and wobbling sexily as they moved.

They both stopped after a minute or so, and I said, "Thank you. I begin my play now."

I decided to start with the doctor, as her ass was relatively new to me. I gave each butt cheek a bit of a slap, watching the flesh ripple, and then a good feel over the smooth luscious skin with my palm, squeezing and squashing the deep white flesh on each. Fuck, I loved that!

Then, I knelt down and gave each cheek a good kiss all over, licking in places. Her ass smelled clean and fresh after the wash, and the cheeks were still wet of course, which I didn't mind at all. Then, I smothered my face all across the doctor's ass cheeks, almost worshipping them by rubbing the sides of my face across her butt flesh and across her ass crack. I then licked along the crack, letting my tongue enter the crack about half and inch, but not more, as I was not sure how much the doctor would allow at this stage, but it was just enough to satisfy me.

Then I said, "Doctor, may I slap your wonderful ass with my cock please?"

"Yes, you may," replied the doctor, "But do not try to penetrate me."

I wondered for a second if the doctor would ever allow me to enter her, or if she was play-acting with me this time, so as not to show how much she was getting aroused with all this.

In any case, I stood up again and started slapping my hard prick against her butt cheeks. There was pre-cum leaking from the tip of my cock, and I wiped that on her ass flesh as I slapped them. Then, directing my cock-head at her ass crack I rubbed my cock all along it, up and down, and then pushed the length of my erect dick almost sideways onto into her crack near the base, so her juicy butt flesh enveloped my dick, squashing its sides and giving me comfort as it felt like I was being wanked by the flesh either side of her ass crack. Fuck!

The doctor's butt had been moving and wriggling in response to my actions and it was a glorious sight and feeling.

Then, letting go of the doctor, I moved to mom, and gave her wonderful ass a very similar treatment to that given to the good doctor, and enjoyed it immensely.

When I finished with mom, I said, "Thank you so much, that was wonderful and very stimulating."

Then the doctor said. "Now Marge, I want you to rub your boobs up and down Jacobs body, starting from his chest and down to his prick."

Mom did so. The sensuousness of it urged my dick to greater hardness, particularly as she rubbed her boobs on my dick and gave it a massage with them. Fuck!

Then the doctor said, "Marge, let me do the same for him."

Mom moved to one side and the doctor did as mom had done. When she rubbed my hard dick between her tits my dick raged up again. "Fuck," I blurted out unconsciously!

"Ah I see this really has an effect on you Jacob," said the doctor.

"Sorry for swearing," I replied.

"No, not at all, you must release your thoughts. Please verbalise your feelings, and you too Marge, as I will. That is the way to gain absolute closeness for the act of fucking that must be performed between you as mother and son. I want you to talk freely between us, and when you are together, so you feel free."

The doctors words were music to my ears, but I decided to play cautious in front of the doctor for now, as I'm sure would mom, although we both loved talking dirty to each other during sex.

My dick was still raging as the doctor stood up again after massaging my dick with her tits in a kneeling position.

There was one thing I was still dying to do which I'd not done so far, and that was to give the doctors tits a suck, and I looked at them again.

I don't know if the good doctor read my mind, but she seemed to sense my desire and said, "Now, lastly before he penetrates you, may I suggest we allow Jacob to orally engage our breasts Marge?"

Mom and I laughed out loud and the doctor also grinned at her remark, pleased it had the desired comical effect.

"You mean suck our tits," said mom bluntly.

"Yes," replied the doctor.

"I have to say, my boobs were aching for some attention after all this activity. You seemed to have aroused me sexually with my son, doctor," added mom.

"Well, I think that needed to happen, somewhat, if he is going to penetrate you regularly Marge," replied the doctor.

Both women now stood next to each other facing me. I actually also felt like inserting my fingers into each of their pussies to finger fuck them simultaneously, but I managed to control myself.

Then they did something which I found incredibly horny, which was to hold up their large tits towards me, offering me their boobs and nipples to suck. Fuck!

I wasted no more time and sucked and grabbed each boob and nipple in turn. I had four to choose from and my mouth and hands moved from one to the next almost like I was some madman, as I buried my face in those glorious mounds of flesh.

"Marge, I think he is ready to enter you again," said the doctor, after I had gorged myself on their tits.

The doctor was now in the middle, standing between mom & I.

"Marge, I would suggest you turn around and face the end wall." Mom complied. "Now, brace yourself against the wall with your hands and let your butt stick out, so Jacob can enter you from behind again."

My dick jerked up at the suggestion, although I actually would have liked to fuck the doctor as well at that moment.

"But before I let him enter you, I am going to do something new -- which is to stimulate him with my mouth."

With out much further ceremony the doctor knelt down in front of me, with mom facing the wall behind her, and took my pulsating hard cock into her mouth, at least half of it's entire length in one go!

"Fuck!" I gasped. "Oh that's good doctor," I managed to blurt out.

"Oh, yes, fuck that's good," I said again, unable to help myself.

The doctor continued sucking me, taking me further into her mouth, and I could feel her saliva and tongue working on me as her mouth clamped onto my dick like some amazing suction machine. Fuck, she was good at this!

Then, having got me as hard as I could possibly be, she stopped sucking me, stood up and standing sideways on, started to pull mom's buttocks apart as she had done before in the inner consulting room.
