@2

Gwen stood up and stepped out of the tub, put on her robe and led mom to her room. She appeared moments later, dis-robed and climbed back in. I was so shocked by what had happened I missed the usual show of her getting back in.

"What are we going to do now?" I asked Gwen.

"John, we've done nothing wrong. OK we're naked but that isn't wrong. Unusual yes, but not wrong."

"I know we've done nothing wrong sis, but is mom going to get naked? Are we going to see her boobs and pussy? I don't know what I'm supposed to do."

"Just try not to stare like you did at mine at first," she said with a wicked smile.

My real head was trying not to panic, whilst my other head was starting to enjoy the prospect of what might happen. I hoped my other head wouldn't embarrass me and get stiff.

A few minutes later mom emerged wearing an old robe of Gwen's. Was she naked or just topless? I'd soon find out.

She stopped where we had hung our robes, faced away and took hers off. She was NAKED. Oh f**k.

She had the same body shape as Gwen, nice wide hips except being older her ass cheeks sagged a little. Then she turned. Her boobs were saggy and in their heyday were probably a B/C cup but her nipples were extremely long and as the cool air hit them, they grew and just like Pinocchio's nose they just seemed to get longer and longer. My eyes were glued to them and I'm sure my mouth must have dropped open. She sort of hesitated as if unsure how to get in. Gwen and I instinctively stood up and helped her step in and sit down. As she stepped in I couldn't help but notice that her pubic hair spread like a thick carpet across her groin. Thick and lush. When she sat down her eyes were level with and directly looking at my cock which was embarrassingly starting to re-act the way cocks do when they see bare boobs and hairy pussies, even if they do belong to your mother. I hastily sat down not wanting to become totally embarrassed.

There was a silence that seemed to stretch for an eternity, but wasn't, before anyone spoke.

"What did you call for mom?" I asked tentatively. "Anything in particular?"

"Well as I was nearby I thought I'd drop by and see how Gwen's building work was going. I certainly wasn't expecting this."

Gwen and I exchanged worried glances. We were probably thinking the same thing. What's she going to say or do? Finally mom dealt with the elephant in the room.

"Listen you two. Since I'm naked too and sitting in the tub with you, then I can't be offended by what's happening. So relax, I'm not mad. You're both consenting adults; well we are all consenting adults. Nudity isn't a bad thing. Can we put the jets on? I'd like to see what it feels like."

I turned them on and mom let out a little squeal. I'm guessing it hit her right on the pussy. She moaned slightly and visibly relaxed. Was she masturbating with the jet too? No, she wouldn't dare; would she? She closed her eyes and once again Gwen and I exchanged a glance. Her breathing quickened and her face flushed red. Then she let out a gasp before opening her eyes and sitting up straighter.

"Sorry about that," she whispered. "That was nice."

"Mom, you didn't!!" said a very shocked Gwen.

"And if I did?" laughed mom. "Loosen up people and close your mouth John."

I did as I was told.

"Don't tell me you haven't done that too?" continued mom.

To protect Gwen I answered by saying no.

"I suppose it would be messy," said mom looking at me.

"Where had this woman hidden my real mother?" I wondered.

"Anyway," she continued. "How are the renovations going sweetheart?"

"All is on schedule and going to plan."

"That's great news. Does that mean you'll be moving back in in a few weeks?"

"Yes three weeks from now."

Suddenly that thought saddened me. I'd be on my own again in three weeks.

"Will you miss her?" asked mom, "or are you looking forward to getting your own space back?"

"Of course I'll miss her. I've enjoyed the company."

"I'm sure you have if you've been doing this," joked mom.

"Mom!!" chided Gwen.

Mom just laughed. I think she was enjoying our embarrassment.

"Have you ever done this before?" I asked her.

"No," she replied, "but I have often thought about it."

"Naked hot-tubbing?" asked Gwen.

"No not naked hot-tubbing per se, just nudity, naturism, skinny-dipping, nude beaches, that sort of thing. But I was never brave enough to try and now with these saggers," she said as she cupped her droopy breasts, "who'd want to see them?"

"Great nipples though." Did I really say that out loud? Oh f**k.

"Thank you, sweetie. Nice of you to say," she said as she pinched and then pulled on them making them even longer. My cock twitched and I hope, since she was sitting opposite me, that she couldn't see it growing.

"They used to be firm and pert like yours Gwen, but age, two kids and breast feeding didn't help. But it did help the nipples," she said with a grin as she pulled on them again.

This time she did notice.

"Well someone likes the view," she said as she looked directly at my cock and her comment and stare didn't help either as I just got stiffer.

"Tea, coffee anyone?" I asked as I climbed out past mom with my stiff cock almost hitting her in the face.

"Be careful where you aim that thing," she said sarcastically.

"That would be nice bro," said Gwen. "I'll give you a hand."

There was no point covering up, so I just put on my slippers and went in to make the coffee. Gwen followed behind.

"What just happened?" asked Gwen.

"I don't know. Did mom cum?"

"I think she did."

As I prepared the cups Gwen sorted out some biscuits and before we could bring them out, mom arrived into the kitchen.

"Probably be easier to eat in here, then, I can head off back home if that's OK."

I got some towels for us to sit on and we sat, naked, around the table. There was an awkward silence as we tried to act natural and not look at each other.

"Listen you two," said mom, "I'm sorry if I've embarrassed you but, I've got to thank you for letting me join you today. I've enjoyed sitting naked with you both and hope you have too. It would be nice if we could do it again."

Gwen and I looked at each other and smiled.

"Mom," I said, "you're more than welcome. It was just a shock that not only were we 'caught' but also that you joined in without any second thoughts. That you willingly let us see you naked. But I think now that that initial shock

is over, it will be easier next time."

"Gwen?" asked mom.

"It will be easier and sure John got to see two naked females in a hot-tub, every guy's fantasy."

"A special fantasy since the naked women were his mother and sister," said mom with a naughty wink.

We all laughed and felt a lot more relaxed. The conversation was still not flowing naturally but we did chat.

"Time I was getting home to your father," said mom,"and don't worry, this is our little secret. Give me a hug then I'll leave you both in peace."

She got up and gave Gwen a hug then me. Her very large and still hard nipples dug into my chest and my cock betrayed me once again as it stiffened against mom's thigh. I was mortified. She, however, said nothing, stepped back so it could be sandwiched between us which didn't help my situation and as her thick thatch of pubic hair rubbed against its sensitive head before nestling against my balls. I got a lot harder and pre-cum starting oozing. Mom seemed to let the hug linger longer than she should. Was she enjoying my hard cock rubbing against her? It twitched and mom smiled. The dreaded tingles were starting. Then, before the tingles got too much she released me and headed to Gwen's room to get ready and a few minutes later she was on her way.

"Hopefully our next session will be sooner rather than later," she said, "and don't worry; I'm not going to make a nuisance of myself by dropping by too often."

Then she was gone. Gwen and I went back to the kitchen table.

"I'll say it again, what just happened?"

"I don't know sis. I just don't know. Did mom just give her blessing to what we're doing?"

"I think so," Gwen said with a grin, "and I think she enjoyed your stiffy rubbing against her pubes."

"Then let's not disappoint her," I said laughing, "and get back into the tub."

With lighter hearts we went back to the tub. I knew things were back to normal when Gwen climbed in as she normally did; only this time she deliberately took her time giving me a long, lingering look at her pussy. My cock stiffened and as she sat down she looked at it.

"I'm glad it enjoyed the view."

"It certainly did," I replied making no attempt to hide my erection.

Once we'd settled Gwen put the jets on. Was she going to copy mom? As if she was reading my mind she said, "Would you mind if I copied mom from earlier?"

"Do you mean to masturbate on the jet?"

She blushed deeply. Her neck and chest grew red.

"Yes," she said quietly.

"You work away sis and if you can give yourself more than one, then all the better."

She gave me her widest smile yet.

"You won't think less of me?"

"Certainly not, especially since I'll enjoy watching."

She shifted her body over the jet and keeping eye contact with me, she started. Firstly she settled herself over the jet no doubt getting her pussy aroused. Then slowly she started, ever so gently moving back and forward letting the jet caress the length of her pussy. Her eyes closed briefly and her breathing became heavier. When she looked at me again it was obvious that she was in the first throes of her orgasm. Her eyes were glazing over and she started to bite on her lower lip.

My cock was rigid beneath the water. It was all I could do to not begin stroking it. I don't know how long I could hold out before joining sis with her wank.

Her back and forward movement then turned into up and down moves. Her breathing got heavier and she stared lustfully at me. I couldn't hold back any longer and stood up exposing my rigid boner to Gwen. She sucked in a heavy breath as she looked at my cock and whenever I gripped it and started to stroke it, she let out a loud moan. Her breathing quickened as did my stroking. She was panting heavily now and her eyes darted between my cock and my face. I could feel my balls starting to tighten as my orgasm approached. The tingling sensations just kept on intensifying. Pre-cum leaked profusely from my cock head. Suddenly I erupted and my cum spurted out in long ropes. My legs buckled and I lost my balance landing back into my seat. It was the most intense orgasm I've ever had and it seemed enough to push Gwen into hers as she screamed, moaned and panted, as her orgasm ripped through her. She too collapsed back into her seat.

For what seemed like a long time the only sound that could be heard was the gradual slowing down of very heavy breathing. I was sure my heart would burst from my chest and I wasn't sure if I was hearing my blood pounding or just felt it so. What an experience!

Eventually our bodies settled and we looked at each other as if to say; did that just happen? Was the silence a feeling of guilt? A feeling of revulsion even?

"Well bro, I don't know about you, but that was awesome," said a breathy and exhausted Gwen.

"It certainly was," I said in agreement.

More silence followed, but it wasn't awkward.

"I don't know if I need a coffee or a drink," laughed Gwen.

"I know what you mean. What if I get us a coffee first?"

"Sounds good to me. Let's eat inside."

Gwen stood up and gave me my usual show as she climbed out. This time it was a wet and still aroused pussy that I was seeing.

"Looks like the box is open," I said.

"Is it indeed," she replied looking back at me from between her legs.

She held her position and slipped her hand between her legs as if to check the accuracy of my statement.

"So it is," she agreed as she proceeded to slip two fingers into her pussy.

I stood up. My cock had stiffened again and was twitching at the scene being played out in front of me. It was so hot I never got the chance to warn her as I shot my second load all over her ass.

She smiled and moaned as her own orgasm raced through her.

"Think I'll need a shower before coffee," she said as she rubbed my jizz all over her ass.

Even that small act made my cock twitch.

Gwen climbed out and went in for her shower. I tidied up, shut the hot-tub down and locked it up for the night.

As I entered the kitchen Gwen came out of the bathroom wrapped in her towel.

"I'll do the coffee while you shower," she said.

In the shower my mind was reeling from what had just happened. Other guys would probably think I was so lucky to get to fulfil a fantasy by cumming over my sister's ass. My mind wasn't letting me enjoy that fantasy. Had we crossed a line? Was the innocence of simple nudity now gone? Was Gwen as conflicted as me? Time would tell.

Once out of the shower I went into the kitchen wearing just my towel. Gwen was sitting on the sofa still wrapped in hers and sipping her coffee. I took my coffee and sat at the table.

The elephant had returned to the room.

"Is she ok with what happened?" I wondered. "If we stop the naked hot-tubbing and Mom drops by again, will she wonder and possibly work out what happened? Will she be annoyed or angry with us?"

These were just some of the thoughts that were whizzing through my mind.

"Are you ok Gwen?" I asked with my heart leaping into my mouth.

She looked at me with eyes that showed the same conflict I was having.

"I think so," she eventually replied. "We got carried away in the heat of the moment and probably did things we wouldn't have thought we'd ever do. But..."

"Here we go," I thought. "We've spoiled the innocent fun we were having by getting caught up in the moment. She won't want to continue."

"...I don't regret it. In fact, I enjoyed it," she continued. "Did you?"

"Did I just hear her correctly," I thought. "Surely not. She enjoyed it?"

"Yes, I did. It certainly wasn't something I thought we'd ever do. It certainly wasn't something I expected to happen, but it did and my biggest fear is that it will spoil the fun we've had exploring our naturist side. Is it wrong of me to think that?"

"No, because I've been thinking the same. I've enjoyed the nudity and the innocent teasing. It's not as if we're going to be wanking and cumming every time we hot-tub; are we?"

"We'd be exhausted if we did," I replied.

Gwen laughed.

I believe the elephant had been banished.

When she'd finished her coffee, she put her mug in the sink, gave me a kiss to the top of my head as she walked behind me towards her room and wished me goodnight.

I finished off my coffee and went to bed too.

Sunday morning arrived with the sunlight streaming through my bedroom window. I'd slept well considering the previous evening's shenanigans. I was just about to get out of bed when there was a soft knock on my door. It opened slowly.

"Are you awake?" Gwen whispered.

"Yes," I replied.

"May I come in?"

"Come on ahead sis."

The door opened fully and Gwen stepped in. She was naked and I was relieved. It seemed our escapades last night hadn't frightened her.

"Can we talk?"

"Of course."

Moving over to my bed, she perched herself at the foot of it, sitting with her legs folded beneath her in a yoga type pose I couldn't remember the name of. It fully exposed her 'box' but sadly this time it was closed.

I threw the duvet off me and sat as well but wasn't able to copy her pose. We were now sitting close to each other, fully exposed to one another, with my flaccid cock lying against my right thigh.

"I hope that what happened last evening won't stop the good times we've been having," she said with a certain amount of nervousness.

"Considering you've entered my bedroom naked and perched yourself on my bed and I haven't complained but in fact joined in the nudity should tell us both something."

She smiled the type of smile that reaches your eyes.

"Then you're good with it continuing?" she asked.

"Yes, if you are."

"I most certainly am," she replied with a huge grin before launching herself on top of me and knocking me onto my back to give me a hug.

She was lying half on top. Her right leg was between my legs while my right leg was between hers. Her arms were around my neck hugging me tight and pressing her right boob hard against my chest.

"Thank you, John," she said. "I was worried we'd lose this new connection."

I wriggled to try and get more comfortable but ended rubbing my thigh against her pubes. Knowing that it was her pubic hair rubbing against my upper thigh starting getting me aroused. This was not good.

My reaction was to try and roll over but that only made things worse as I ended up on top of her missionary style with my cock right against her pussy. I was starting to panic but Gwen wasn't. I thought she'd have let me go and pushed me off, but she didn't. As I tried to get off her, she tightened her hug, looked me in the eye and said, "Don't be worrying big bro. It's not going anywhere. Enjoy the hug."

I relaxed and enjoyed the feeling of her beneath me. My cock did react but didn't go into full boner mode, much to my relief.

"Shall we get our day started," she asked.

"I'll go put the coffee on," I replied.

I climbed off leaving a pre-cum string connecting my cock to her pubic hair, then reached out to help her up. Spreading her legs to get more push she revealed her now slightly open and moist box. I wasn't the only one who was getting aroused.

Breakfast was eaten naked. I had my usual cereal while Gwen had fruit mixed with yoghurt. There was silence as we ate but it wasn't an uncomfortable one and it was as we sipped our coffee that Gwen tried to explain how she was feeling.

"The reason last night didn't scare me nor put me off what we've been enjoying was all down to Mom."

"How so?" I asked puzzled.

"First of all, she didn't go ape shit with us being naked and she joined us. So, she must have approved. Secondly, she actually masturbated in front of us and orgasmed. If she was confident and comfortable enough to do that in front of her children, then what we did after must be ok too."

"You have a valid point," I agreed. "If she can openly cum in front of us then she can't complain if we do it in front of each other too."

"Precisely," continued Gwen, "and thirdly, we're not going to have sex. We both know that. We might have feared it could happen, but we know deep down that it won't..."

"She had more confidence than I had," I thought but she was right though, I had no desire to have sex with her; but, who knows what could happen in the heat of the moment. I just hope I never prove her wrong.

"... that's why I felt comfortable enough jumping on you in bed and ending up underneath you. We also don't have to wank and cum each time we use the tub either. That would only spoil things, but that's not to say that we shouldn't if the notion takes us."

"Ok," I said. "What's the order of play for today? When would you like to hot-tub? After lunch or this evening before bed?"

"This evening would be nice then we can just go to bed after," she said.

"Hopefully separate beds," I said with a wink.

"You're incorrigible," she said throwing a cushion at me.

We both laughed and whatever tension there was evaporated.

After getting showered and dressed we sat about the house doing our own things. Lunch came and went. Dishes were done and I did the last of my ironing. It was after 4pm and I was about to ask Gwen when she'd like to hot-tub when there was a knock on the front door. Opening it I saw Gwen's friend Sarah."Hi John, is Gwen in?"

"Yes, come in. Gwen, it's Sarah," I said.

Gwen came into the hall and they greeted each other with a hug.

"I'll leave you girls to it," I said as I headed to my room to give them privacy.

I must have dozed off because I woke with a start to find Gwen sitting beside me on my bed.

"Sorry bro, but Sarah was not in a good place and just needed a shoulder. It's after 6 o'clock and too late I suppose to get the tub warm enough to use and enjoy it."

"Yeah, it is."

"I'm sorry," she said again. "I hope it didn't spoil your evening."

"Was it spoiled?" I wondered. "Had I been looking forward to seeing my sister naked again? Was I becoming a perv?"

"Disappointed? Yes, but spoiled? No. Life happens sis. Life happens. Anyway I should have turned it on earlier," I said instead.

"You want some coffee?"

"Yes please."

She left to make the coffee and I got up and followed her.

"Is Sarah ok? Is she struggling with being single again or is she thinking about taking her guy back?"

"I think she might take him back. I've told her what I think but said the final decision was hers and I'd support her whatever that decision was."

"He seems to be a loser if he treats her badly."

"Don't know what his game is. Sarah's a lovely girl. A catch in anybody's book."

"She is," I agreed, "but before you say anything I'm not interested. She's not my type whatever that cliché means."

Gwen just smiled, said nothing and brought me my coffee.

"It's just as well we weren't doing our naturist thing or actually in the tub when she arrived," added Gwen. "That would have been embarrassing."

I agreed and we both laughed.

Friday rolled round once more. I'd already set the timer for this evening and at about 7pm we got into the tub. We sat and relaxed in our usual comfortable silence. We'd decided over dinner to try and have two shorter sessions rather than our usual 30-45-minute session. It would be interesting to see what if any difference it made.

After 25 minutes we climbed out and went in to the kitchen to replenish our drinks and feed on some crisps and nuts. I sat at the table while Gwen sat yoga style on the sofa showing off her glorious box. It wasn't as aroused as it had been but then neither was I. We chatted casually and talked over when we'd want to use the tub so I could set the timer.

"Would it be safe to use it in the afternoon and then just again before bed?" she asked.

"I don't see why not. There'd be a good gap between our sessions so it should be ok."

"If we get our chores done and lunch sorted by 1pm we could be ready for 2pm then."

"We could indeed," I said. "I'll set the timer so it's ready for 2pm and maybe 9pm?" I said.

"Sounds like a plan," she said. "Ready for session 2?"

"Let's go," I said as I went out to take the lid off the tub.

Our second session was quiet like the first. It seemed we were both tired from our week of work. It was a nice session and whilst it was in no way erotic, apart from the nudity, I found myself really enjoying it and had a pang of guilt for thinking about the lack of sexual exhibitionism. We didn't need the orgasms. They were nice when they happened but the lack thereof didn't spoil what we had.

"Bed time for me bro. I'll take everything in while you sort the tub out. Do you mind if we leave the dishes until the morning?"

"Not at all sis. You sort yourself out and I'll sort out here."

Whether it was the tiredness or me just getting used to it, but I didn't even ogle her pussy as she climbed out and that didn't bother me.

Saturday morning arrived and it started with some disappointment. Gwen knocked on my door and asked if she could come in.

"Of course," I said. "Come on in."

She looked a bit down and sat herself at the end of my bed in her now usual yoga-type pose. I'd tried to find out its name and think it's called the Lotus. It showed of her box as usual and it was firmly closed. Not even a hint of moisture. Something was wrong. Anyway, I asked why the sad face.

"My builder is just off the phone with me."

"Oh shit," I thought. "There must be something seriously wrong if it's affected her like this."

I prepared myself for some bad news.

"Is there something wrong with your flat?" I asked with concern.

"No."

"Then what's wrong?"

"Nothing, that's the problem."

"I'm confused sis."

"My flat is ready."

It took a while for me to understand what she meant. Her flat being ready meant she could move back and she didn't really want to do that.

"Is that not a good thing?" I asked.

"Yes, but it means me moving out and I've really enjoyed living here with you and I don't mean the nudity and the hot-tub and the wanking and the..." she said rather rapidly.

"Whoa sis," I said interrupting her. "Slow down. Slow down."

I leaned forward and took both her hands in mine.

"I've really enjoyed you staying here too and like you I don't just mean the naughty things either," I said with an exaggerated wink. "But what happens when one, or both, of us meets someone we'd like to get intimate with. That's going to be very awkward if we're living together. I'm going to miss coming home and being able to tell someone about my day. Someone I can rant to if I'm having a bad day as well as being able to sit down and share a meal with. I'm going to miss all that too. The naughtiness wasn't bad either," I said with a smirk.

She let go of me and gave me a playful swat.

"I just knew it was my boobs and box were all you were interested in," she said trying hard to smile through her sadness.

"Come here," I said.

She moved up the bed and I hugged her.

"I'm sorry John. I'm acting like a spoilt child."

"You're not," I said. "We've had a wonderful few weeks and you're sad that they've come to an end, even though we knew this day would come."

"That's true," she agreed.

"However, it doesn't mean that everything has to change. For example, we can still hot-tub; we can meet up at weekends; we can share takeaways. We can keep doing more or less what we have been doing except it won't be every night."

"You wouldn't mind me dropping over?"

"Of course not. Why would I? How then am I going to see your boobs and box?"

That raised a genuine smile.

"Thanks John."

"You're welcome sis."

"Well you better have a good look now," she said as she got off the bed and jiggled her boobs with her hands. "It could be a while before you see them again."

We both laughed.

"Listen sis, you go do what you have to do and maybe we'll get our evening session in the hot-tub."

"We'd better," she said with mock anger, then left my room.

Once she closed the door behind her I let my true feelings show. Like her I was sad that this had all come to an end. I was serious when I'd said our living together could get awkward if we each met someone, but that didn't ease the disappointment. It was a sad start to my day.

The rest of the day went as most Saturdays go; housework and laundry and our hot-tub session that evening was a very flat affair.

Sunday came and went with nothing exciting happening. We had an early evening hot-tub but it too was very subdued. We were not in a great place.

The following week we were more like ships passing in the night. After work Gwen was sorting out getting her new furniture delivered etc. ready for moving back in that weekend. For her last Friday staying with me we had decided on a Chinese take-away, some wine and possibly our last hot-tub session for a while. It was a sad week.

At last Friday arrived. I'd already set the timer for the tub and collected our take-away on my way home. By the time Gwen got home I'd everything set out and even some candles to try and make the dinner that little more special. She thanked me for my effort and we were just about to start when mom arrived.

"Ooohhh, Chinese," she said. "Is there enough for me?"

Fortunately, there was as we always tended to order more than we needed.

"Of course there is mom," I said brightly.

"Sit down and I'll get you a plate and cutlery."

We ate our meal chatting about our day and finding out if Gwen had all she needed for moving back home the next day.

"Is the hot-tub working tonight?" asked mom.

With mom arriving I'd forgotten about the hot-tub and our plans to use it one final time.

"Yes, it can be," I replied. "You wanting to use it?"

"It would be nice," said mom. "I really enjoyed it the last time."

"I'm sure you did," I thought.

"We'd need to leave it for a while though until our dinner has settled."

"Of course," mom agreed.

A little later I checked the hot-tub. The water was ready and I'm sure we would be too. I announced all was ready and went to my room to change. I wasn't sure whether it would be a nude session so I put on some shorts and when I arrived back out mom and Gwen were already in.

"Who's being a party pooper," joked mom when I arrived back out.

"What!" I replied somewhat confused.

At that, mom stood up revealing her totally naked body.

"I thought you did this nude," she said.

I had a quick look at Gwen who just rolled her eyes and said nothing. So, I dropped my shorts and climbed in. Thankfully there was no stiffy of any description to embarrass me.

Mom behaved herself when she asked if the jets could be turned on though she did giggle like a school girl much to our amusement. The chat was mainly mom quizzing Gwen and Gwen relating her plans to us and hoping we could help with the move. I told her that she didn't need to ask; the help was there as and when she needed.

There was no ogling the naked bodies as we got out. I put that down to the sadness of Gwen leaving rather than me getting used to seeing them. We wrapped ourselves up in our robes and went inside and it was as I was making the coffee that mom made her announcement.

"Do you mind if I sleep over tonight. It's a bit late to be heading home and the hot-tub has tired me out somewhat."

"Not at all mom," I said and secretly motioned to Gwen to come and help so we could discuss this.

"Need a hand with the coffees John?" she said.

"Thanks sis if you don't mind."

Once over at the coffee I whispered, "Where are we going to put her?"

My room was the only room with a double bed.

"The two of you can sleep in my bed and I'll sleep in yours," I whispered.

"Do I have to share with her?" said Gwen knowing it was either that or someone sleeping on a not very comfortable sofa.

"Fine," said Gwen. "I'll say to her."

Carrying the coffee back to the table we noticed that mom had slipped off her robe. Her slightly saggy boobs were topped with very stiff nipples. Gwen and I looked at each other.

"Is everything alright mom," asked Gwen.

"Yes sweetheart. I've been getting hot flushes lately. The joys of getting older," she said with a hollow laugh.

"Now don't be worrying about sleeping arrangements," continued mom. "I'm happy enough to sleep on the sofa."

"You can't do that mom," protested Gwen. "Me and you can share John's bed and he can take mine. Would that be ok bro?"

"Yes, not a problem."

"Well it would be," said mom. "These hot flushes make it almost impossible to share a bed with anyone."

"But you can't sleep on the sofa," I said. "It's very uncomfortable as a bed."

"There's no other option," she said.

"There is," piped in Gwen. "You sleep in my bed mom and I'll share with John."

If mom was shocked by that, she didn't show it and I hope I didn't show it either.

"You sure sis?"

"Yes, if you don't mind."

"Not at all," I said, wondering where this could possibly be going.

"Well, if that's all settled I'll head off to bed now. Goodnight."

"Goodnight mom," we both said.

She got up from her seat and her robe slipped off. Picking it up she gave Gwen a hug first, then me. Her very stiff nipples pressed against me and my cock twitched. If she felt it, she never said.

As mom left I looked at Gwen. She put her finger to her lips to give the "shhhh" message. Then taking my hand she led me to my room. To say I was confused would be an understatement.

"Don't be panicking bro. It'll be all right."

"Sis, as you are well aware, I sleep naked."

"Mmmm," she said waggling her eyebrows, "so do I." And she went back into the kitchen to tidy up.

I was definitely confused. Over the past number of weeks, we'd gotten used to being naked in front of each other and on one occasion had openly cum in front of each other, but sharing a bed, naked; that was altogether a different matter. Was this a good idea? Were we leaving ourselves open to hurt? Confusion over what to do plagued me.

I went back to the kitchen to help with the tidy up but Gwen had it done.

"Tea, coffee?" I offered.

"I've already had too much coffee," she replied. "What about a beer? It's a bit early to be heading to bed."

She was right it was too early, especially since we'd be sharing a bed and naked too. For once I was in no hurry to get to my bed.

"A beer sounds good," I replied.

I sat at the kitchen table while Gwen took up her usual spot on the sofa. Thankfully this time she didn't sit in her yoga pose so I was spared having to avoid the temptation of checking if her box was open or shut and her robe covered everything else. The atmosphere was a little tense and we tried to make small talk, but it was obvious that there was an elephant of some description in the room.

"Want another one?" asked Gwen.

Since it would delay getting into bed for a while longer I agreed, so we had a second beer, which stretched to a third.

"If we don't head to bed we'll run out of beer," joked Gwen.

"I suppose we should," I said hesitantly.

"Please John. Don't be worrying. Nothing is going to happen."

Then taking me by the hand she led me to my room. To say it was strange being led to your bed by your sister would be an understatement.

Once inside she removed her robe revealing her wonderful naked body. Her nipples were stiff. The cold? Or arousal? I didn't want to know the answer. Turning down the bed she leaned over and climbed in, giving me the first glimpse of her pussy for what seemed like a long time. I followed suit and thankfully my cock didn't re-act to the very sexy view I'd just witnessed. I pulled the duvet up around us. Gwen rolled on her side to face me. I stayed on my back. Putting her arm across my chest she hugged me, kissed my cheek, said goodnight and rolled away.

I lay confused and wondering how I'd ended up naked in bed with my naked sister. The past few weeks had certainly been interesting and the images of Gwen's aroused pussy along with mom's nudity and openly orgasming in front of us certainly got me aroused. As my cock started to stiffen I rolled away from Gwen and tried to think bland thoughts and hoped I'd get to sleep soon.

Sleep must have arrived as my next memory is waking up in a spoon hug with Gwen; my morning Woodie wedged between her ass cheeks and my arm draped over her with my hand on her boob. It took a while for me to realise what was happening. Then out of pure shock I shuffled back and rolled over.

"Good morning bro," said a tired voice. "Sleep well?"

Had my moving just wakened her or had she been awake and felt my cock on her ass and my hand on her boob? What was I to do? Play it cool and say nothing or apologise?

"I think I did," I said wimping out.

"That's good. I think I did too. Three beers probably helped as well," she said laughing.

"They probably didn't hurt," I agreed.

"I'm surprised mom hasn't been in yet to waken us."

"You're right," I said. "Wonder if she's already away to collect dad?"

That thought seemed to spur us into action. The last thing we needed was dad to arrive and witness our nudity.

"You get showered sis and I'll get breakfast started. Cereal and then toast?"

"Sounds good to me."

In her hurry to get out of bed, Gwen climbed over me and was straddling me when mom walked into my room. Her eyes and mouth opened wide at the sight before her. My brain cried, "Oh f**k."

Gwen was the first to re-act.

"Mom, this isn't what it looks like. Look?"

Then sliding down my body she revealed my now very swollen cockhead nestling between her thighs.

"I was just climbing over him to get out of bed."

Even though I was worried about how we must look and how mom might re-act, my cock wasn't concerned at all and the weight of Gwen sitting on me, as well as the heat from her pussy, had put my cock into major erection. Then by sliding down as she did and tugging my foreskin back, she didn't help matters. The tingles were starting to develop and intensify in my ball sack. I was hoping she'd get off soon before I embarrassed myself and possibly made matters worse by cumming over her legs.

"Well, it's not a sin if it's not in," mom said.

Her total lack of re-action was not what we expected and we looked at each other in total shock.

Gwen climbed off the bed revealing the extent of my erection. It was so stiff it lifted clean off my tummy and almost pointed straight up. I had never seen, nor felt it so hard.

I could feel my face heat with embarrassment as I lay there in full view of my mom displaying a raging hard-on.

Mom stared at it and then slowly walked towards me, continuously looking at my now throbbing cock. What was she going to do?

"Boys and their morning erections," she said rolling her eyes.

Standing right by my bed, she slowly reached out and touched its head. It twitched at her touch. She jerked her hand back, squealed, then laughed as the pre-cum left a string between her finger and my cock.

"What the f**k is going on?" my brain asked.

More determined, she reached out again and gently trailed her fingernail down the back of my cock and onto my scrotum. The sensations were truly amazing and still my brain wanted to know what was going on. I was confused but very much aroused. As she gently dragged her nail across my ball sack the tingles were starting to go into overdrive. I looked at her. She was looking intently at what she was doing, then bit her lower lip. Was mom getting aroused? I immediately chastised my brain for thinking that. Mothers don't get aroused by their son's cocks.

Trailing her finger back up my cock, the tingles started to get out of control. It started twitching uncontrollably. My orgasm was fast approaching. Surely she was aware of what she was doing? Then just before I erupted, she wrapped her hand gently around my cock and aimed it at herself.

I exploded; a huge, guttural groan escaped my lips.

My first spurt landed on her shoulder. The next two landed on her tits. The rest landed on her tummy and as she aimed my cock the last couple landed on her thick bush.

I was completely drained of energy as well as cum. I watched as my cum ran down her body. Then releasing my cock, she massaged my cum into her skin; her tits, her tummy and her pussy.

Gwen just stood there in shock. Her eyes wide and her mouth open. She was, no doubt, thinking the same thoughts as me.

Did that just happen?

Was that our mother?

It must be her evil doppelganger?

What's going to happen next?

That last thought was soon answered as mom licked her fingers, told us breakfast was ready and to come and get it.

Then she turned and left as if nothing out of the ordinary had happened.

Gwen and I exchanged glances of puzzlement and disbelief before following her out.

Breakfast was eaten in silence. Each of us lost within our own thoughts.

"I'm going for a shower. Can you two tidy up?" asked mom.

"Yeah, not a problem," said Gwen.

I was still speechless. Still trying to understand and process what had just happened.

Gwen cleared her dishes and mine to the sink, then came back to the table, took my hand and led me back to my room."John?" she asked. "What just happened?"

"I...I don't...rightly know," I replied.

"Do we need to worry about mom?"

"I hope not."

Before we could continue, mom announced the shower was free.

"You go first sis."

She glanced at my thickening cock and grinned.

"Ok."

My thoughts were firing all over the place and my body was betraying me with the start of another stiffy. Why was I finding this situation erotic? Why wasn't I feeling ashamed?

"Shower's free John," shouted Gwen.

"Thanks sis."

Grabbing a towel to cover my now stiff cock, I went for a shower. Under the hot water I replayed what had happened already as I stroked my cock. Faster and harder I went. I remembered my mom's long and very stiff nipples; the tingles were building. Once I got to the memory of mom stroking my cock with her hand and pointing it at her as I came, history repeated itself, only my cum went over the wall and not mom's body.

Once my heart rate had settled I got showered quickly and rinsed my cum off the wall. I was hoping I didn't take too long and make it obvious I was wanking.

When everyone was ready we headed over to Gwen's and worked on getting it ready for her to move back in.

It was a long and tiring day. Dad had to leave early and said he'd be back to pick mom up later; however mom said it wouldn't be necessary as she would stay with me again. So off he went saying he would see us tomorrow.

"You don't mind me staying again, do you son?"

"Not at all mom. Not at all."

"We can use the same sleeping arrangements," she continued.

Gwen and I glanced quickly at each other. She smiled so I knew she didn't mind.

"Will the hot tub be on tonight?" asked mom.

"Yes it should be. You wanting to use it?"

"I'm hoping it will ease my aches and pains from today."

"It certainly will," I agreed. "We'd need to eat soon though so that we can get in the tub later. Is everyone ok with pizza?"

They were, so I went to get some while mom and Gwen worked on.

As we ate the pizzas, it was obvious that there was an elephant in the room. Who would try to sort it? I was hoping mom would.

When we were finished, I cleared away the boxes and napkins and made more tea. Once back at the table good old mom broached the subject.

"When we use the tub later, I hope it can be as before," she said.

"What do you mean mom?" asked Gwen.

"Naked," she replied.

"And why wouldn't we?" replied Gwen.

"Well...after this morning I thought that our naturism might have come to an end and I don't want it too."

"Do you want it to end John?" Gwen asked me.

I hesitated fractionally too long and they both looked sad.

"No, I don't," I said eventually.

"John, sweetheart," said mom. "I can understand if you feel reluctant or even frightened by what happened this morning. But we didn't do anything really wrong."

"I know mom. It was just kind of weird."

"I understand, but when you think about it, we didn't really do anything different apart from me touching you and if you hadn't been so aroused I wouldn't have and you wouldn't have shot your load. Granted, me touching you was naughty and aiming your cum at me was naughty too but it wasn't really too wrong," she said emphasising the too.

"My cumming in front of you was embarrassing mom and then you holding my cock and spraying your body with my cum was really strange and felt very awkward."

Gwen sat silently, listening intently and letting us clear the air.

"I'm sure it did and in fairness to you I should either have asked your permission or restrained myself. But, it was a chance I didn't want to miss. Your father, like me, is ageing and while we have a healthy sex-life, his cock doesn't get as stiff anymore. Just like my boobs sag while Gwen's are pert."

Gwen blushed.

"So I took the opportunity to hold a really stiff cock once again. Sort of scratching an itch, so to speak. Can you understand?"

"Yes mom, I can."

"Thank you. Shall we get ourselves sorted and get home to the tub?"

It took a few minutes to get ourselves organised and on our way back to my house.

Once there, mom announced she'd grab a quick shower to freshen up then get into the tub. Gwen decided to do the same so I went to check that the timer had come on and the tub was ready.

Mom came out of the shower in her robe, while Gwen sauntered to the shower, naked and carrying her robe.

"Beer or wine folks," I asked.

Mom didn't mind and Gwen said beer, so beer it would be.

By the time I had the drinks and nibbles sorted and left out at the tub, Gwen was out of the shower and both women headed to the tub while I had my quick shower.

Afterwards as I approached the tub they seemed to stop talking.

"What were they chatting about that they had to stop?" I wondered.

Or was I just being paranoid?

I hung my robe up and climbed in. Gwen handed me my beer; we said cheers and had a swig.

We sat in a fairly comfortable silence. Mom and Gwen had their eyes closed, no doubt lost in their own thoughts, while I went over in my head what mom had said earlier in Gwen's. I could understand where she was coming from and if you needed to scratch a sexual itch, then surely it was better if it was with a family member than a stranger and I could understand the impulse. Many times, when Gwen 'flashed' me I fought the urge to touch her, especially when she flashed her pussy as she climbed out of the tub. So, I couldn't blame mom for feeling the same impulses. Surely, they were natural urges.

"Ready for another beer?" asked mom.

Shaken from my thoughts it took a few seconds to say yes.

Then it happened.

Mom climbed out of the tub the way Gwen did, showing her naked pussy in all its hairy glory. Did she realise? Was she trying to 'reward' me for touching me earlier?

Gwen and I looked at each other and she just shrugged.

When mom arrived back, she handed out the beers and climbed back in showing her pussy to us both yet again.

It was another few minutes before anyone spoke and again it was mom.

"Do you know why I never freaked out whenever I caught you both naked in the hot-tub, or when I walked in on you when Gwen was straddling you?"

"I suppose we both have," I said looking at Gwen who just nodded.

"Well let me tell you why," she said.

"When I was 18, your Uncle Bill would have been 19; he'd just come home from uni for the summer. I went into the bathroom and accidentally saw him naked. He'd forgotten to latch the door, a habit he'd gotten out of because he didn't have to do so in his uni digs. Naturally both of us were shocked and embarrassed but I got a good look before I regained my senses and left."

She smiled broadly at that memory and I do believe her neck flushed red and her nipples stiffened.

"For the remainder of the day we avoided each other as best we could and at dinner mom and dad sensed there was something wrong, though they never said anything. It was a few days later before we had the house to ourselves once again. Bill, like a typical teenage guy, always lay on late in bed but while he was having breakfast, I broached the bathroom incident. I apologised and apologised and kept saying sorry until he said he'd got the message and not to worry as he was sure I'd find a way to repay him."

"Did he mean what we think he meant?" asked a curious Gwen.

"Well," said mom smiling broadly. "I asked him how I could do that and his reply stunned but didn't really surprise me. 'Well, you saw me naked,' he said. I wasn't prepared to strip off for him but saw no harm in letting him see my boobs. So, I stood up, took off my t-shirt and removed my bra. My nipples stiffened and I saw him out of the corner of my eye try to discreetly adjust his crotch. I let him look for what seemed forever before putting my top back on but staying bra-less for the rest of the day."

"Wow," we both said. "What happened next?"

We were like 2 kids being told a bed-time story who couldn't wait to hear the next chapter.

"It wasn't everyday that we got the house to ourselves, so it was a few days later when the next part happened. Once again, your Uncle Bill had a lie-in and when he came down for breakfast I was already dressed for the day. As he ate, I noticed him glancing over at me quite a lot, so I asked him what was wrong."

"And?" we both chorused.

Mom laughed at our enthusiasm.

"And he asked why I was wearing my bra as I'd left it off the last time."

"What did you say to that?" asked Gwen.

"I told him I didn't make a habit of running about bra-less and it was just that one time to pay him back."

"And?" we both chorused again.

Mom smiled then continued with her story. As she did, she looked off into the middle-distance reliving those long-ago memories and once again her chest flushed and her nipples stiffened. I'd noticed that Gwen's nipples had also hardened as had my cock.

"'You saw me completely naked,' he told me and I just saw your boobs," she said.

Gwen's eyes opened wide and her jaw dropped open.

"'You expect me to get naked?' I said to him. 'Fair's fair,' he replied. I thought about it for a while then made him a proposition to see how brave he was. 'Well,' I said to him, 'if you want to see me naked then you have to get naked too.'"

"What did he say to that?" asked Gwen, who seemed to taken the role of interviewer.

"For a while he just said nothing, then said ok let's do it. I was wondering if he was calling my bluff now, but he got off the chair and took off his top and shorts. I was a bit stunned as I didn't think he would do it. So, I had to carry out my promise and standing in front of him I took off my top, my bra, then my skirt and finally my panties. It was the first time I'd ever been naked in front of any guy and apart from the shower incident it was the first naked adult cock I'd ever seen. He later told me that I was the first naked female he'd seen. He'd seen topless girls on beaches but never naked ones."

"What happened next?" questioned Gwen.

"We stood awkward and somewhat embarrassed in front of each other, looking and admiring I suppose. Then we got dressed again, I stayed bra-less and we said nothing more about it for a few days, even when we had the house to ourselves.

Then on a Thursday evening mom said that her and dad had to go away for the weekend. They'd be leaving the next morning and returning Sunday evening. She'd stocked the fridge and freezer for us and left some money in case we wanted to order in. It was the first time we'd ever been left alone overnight and I wondered what could happen.

I'd already decided I'd go bra-less for the weekend but next morning I thought I'd be a bit more daring and wear something a bit more risqué. Do I wear a tight top to emphasise my bra-less boobs and show them off? Or do I wear a loose top and do plenty of bending over? Looking through my wardrobe I came across a vest top I'd forgotten about. It was perfect and if I was careless enough, I might have the occasional nipple slip and paired with a mini-skirt I would have a lot on show.

When Bill arrived down for breakfast he stared, swallowed hard but said nothing and throughout the day I had the occasional accidental nipple slip. Finally, as we ate pizza later while watching tv he asked what I was playing at. I acted innocent and said I didn't know what he meant. He just raised his eyebrows and said for all the boobage and thighs I'd been showing all day, I may as well be naked. When I asked if he was complaining he said no. I asked if he wanted me to be naked, he said it wouldn't bother him one way or the other; but his answer secretly revealed he hoped I would.

'Well,' I said to him. 'I'm game if you are.' And so, we stripped off and that was the start of a few summers and holidays of us enjoying each other's bodies."

"What all did you both get up to?" Gwen asked.

"Well, as I said, ours were the first naked bodies of the opposite sex we'd ever seen. We also learned from each other. We never had sex nor did we masturbate each other, but we did masturbate in front of each other to see what it was like. So, your Uncle Bill's cock was the first I saw cumming. It was also the first erection I touched and felt. My pussy was the first Bill saw and I let him see and touch my clit. In a way it helped us for when I met your dad and he met Alice."

"When did it all stop?"

"It stopped when I met your dad. It didn't feel right after that."

"Did you miss it?" I asked.

"Yes, it was sad when it stopped. We both knew it would have to stop sometime, but it was sad when it did."

"I always wondered why you and Uncle Bill seemed so close and was worried why John and I weren't like that, but now I understand why."

"Yes, it did bring us very close as I'm sure you both feel that way now."

It wasn't until mom said that, that I realised she was right. Gwen and I had grown a lot closer together since we started our new life-style and I knew what mom meant when she was sad at it ending. I was now feeling that way too with Gwen now moving back into her own flat.

"So," continued mom, "you can now understand why I didn't freak out with you two and I hope you still manage to keep it going even though you'll be living apart."

"Me too," said Gwen looking directly at me.

I smiled and nodded. This chapter has ended but I hoped a new one was beginning.It was about six weeks later, when a very depressed Gwen rang. It was Saturday; it was 4:35pm.

"Hi sis, how's it going?" I asked.

"Not too good John. Do you mind if I drop by?"

"Not at all. Are you ok?" I asked.

"I'll fill you in when I get there."

The brief phone-call worried me and I was anxiously awaiting her arrival. I kept telling myself it was nothing serious. We'd only used the hot tub twice more and not at all since she'd met her new boyfriend Jim.

At first, I suppose I was slightly jealous and I'd missed her company. I'd questioned myself as to whether that was all I missed and after many quiet evenings thinking about it, I realised I also missed the nudity and our closeness. It re-ignited that conversation in my head.

What was it I really missed?

Did I want to be a nudist? I don't think so.

Did I want to have sex with my sister? Most definitely not. I'd exhausted that line of thought a couple of weeks after Gwen stopped coming over. I knew in my heart that that was not what I missed nor wanted. I did miss the intimacy though. The thrill of seeing her naked and parading naked in front of her. Did that make me an exhibitionist? I don't think that either. I was only comfortable doing it in front of her and Mom, I couldn't envisage doing it with anyone else. So, I'm not an exhibitionist either.

My thoughts were interrupted by Gwen letting herself in.

"Coffee? Or something stronger?" I asked.

"Stronger please," she replied with a heavy voice.

"Beer do?"

"Yes please."

When I came back with two beers she asked if we could maybe hot tub later. I said it wasn't a problem and went to turn it on.

"Are you ok?" I asked when I returned.

She didn't reply straight away. Her eyes moistened. I was worried but gave her space to answer when she was ready.

"Me and Jim have parted," she eventually said.

In a way I was glad. Not because of any jealousy but on the few occasions I'd met him, I never liked him. Maybe it was big brother syndrome kicking in, but I just didn't trust him.

"What happened?"

She took a long swig from the bottle and told me what had happened over the past few weeks. It seems that all he was interested in was getting into her pants, her words not mine and when that didn't happen as soon as he wanted, he left.

Another swig from the bottle and it was empty. I got her another.

There was a comfortable silence while we both sipped our beers; or should that just be me sipping as Gwen quickly finished hers. I finished mine off and fetched two more.

"You'll need to slow down sis if you're wanting to use the hot tub."

"Sorry John, I'm not great company. I'm more annoyed with myself."

"Why?"

"I should have realised what type of guy he was."

"But you did. That's why you never let him 'into your pants'. Deep down you knew he wasn't right for you and you proved your instincts correct. You should be proud of yourself."

"I suppose you're right. Do you think the tub would be ready yet?"

I went out and checked. It wasn't quite ready.

"How long do you think?" she enquired.

"Ten minutes or so should do."

"I'll go and get ready," she said.

A few minutes later she returned wearing a robe. She settled herself on the sofa in her usual lotus pose exposing her quite thick bush. My cock twitched.

"Any more beer?"

"I'll go change and bring you one back."

I took my time changing for two reasons:

1. I needed time for my stiffy to soften;

2. I needed to slow down Gwen's drinking before getting into the tub.

I arrived back but instead of giving her her beer I went out to check on the tub and left the beers there.

"It's ready now," I announced.

Gwen leaned further back so she could unfold her legs and in doing so showed off her glorious pussy. Her thick pubic hair had all grown back. It was a wonderful sight to behold and as she spread her legs, she revealed a slightly moist pussy. Once more my cock twitched and started to rise. Why was I getting stiff? I'd seen all of her body before and in more detail, especially the time when she deliberately bent over and using her fingers spread her pussy lips to let me see. What was so different now?

She stood up a little unsteadily and giggled. The beers were having an effect.

I followed her out in case she would fall. At the hot tub she removed her robe and hung it up, then leaning forward and leaning on the tub edge she stepped into the tub.

"Have you missed the view?" she asked waggling her eyebrows as she looked back at me.

"Of course, I haven't," I replied with a laugh.

"Liar."

She was right, I thought. I had missed it. Was I getting pervy again? Just before we stopped using the hot tub, that view would not have gotten any reaction from my cock. Now I was struggling not to get stiff.

As she settled herself into her usual seat, I disrobed and climbed in. Thankfully I wasn't too stiff and she wasn't looking. Once settled I passed her a beer, we said cheers and sipped.

Gwen sat back, closed her eyes, relaxed and sighed.

"I've missed this bro. I knew I would but didn't realise how much though."

"I've missed it too. Not as much fun doing it solo."

"I'm sorry about that John. I should have made more of an effort to get over more often."

"You've nothing to be sorry about. You had more important things to do."

"A lot of good that did me. Bastard."

"His loss sis. His loss."

Gwen finished her beer and fell silent.

"Are you ok sis?"

"Yes, just still annoyed with myself. Any more beer?"

"You sure you want a fourth?"

"Let's live dangerously," she said with a schoolgirl giggle.

I wasn't sure if she should have another but I got just her one. If she got too drunk, I'd need to try and stay somewhat sober to look after her.

This time she sipped her beer slowly and we sat quietly each lost in our own thoughts. I was worried that her experience with Jim would either put her off dating for too long a time or make her more willing to have sex earlier than she would like to. I never really liked him, but now I really hated him and what he'd done to Gwen's confidence.

"Think I'll get out bro and get myself home."

"I think you'd be better off sleeping over sis. You've had a bit too much to drink."

"I'm fine bro," she slurred.

The four beers and the effects of the hot tub had made her drunker than she realized. It wasn't until she tried to stand up and get out that she understood. Losing her balance, she fell back into her seat and let out a drunken giggle.

"Oops, I think you might be right."

I stood up, stepped out and held out my hands for her. Taking my hands, she pulled herself upright and as she tried to step out, she lost her balance and fell into my arms. Putting her arms around my neck she pulled herself into my chest and tried to step out of the tub. Her stiff nipples were pressed against me as she stepped out right leg first. She hopped up and down as she tried to get her left leg out of the tub and in doing so her right leg rubbed against my cock and it started to stiffen. This was not going well. Eventually she climbed out and staggered back into the kitchen. I gave her a towel to dry herself but she was so unsteady she couldn't do it.

"Stand still sis and I'll dry your back and legs."

I gently dried her shoulders and down her back skipping quickly over her ass and down the backs of her legs. She moved her feet apart so I could dry the inside of her legs too. Moving round to the front I dried her feet and up the front of her legs and then her tummy, carefully avoiding her crotch and the tops of her thighs. I certainly wasn't going to get that intimate. My conscience was already giving me a hard time doing what I was doing without drying her intimate bits too.

I stood up and as I dried her arms, I became conscious of her boobs jiggling. Not good for me as my cock started to react.

"There you go," I said.

"You missed bits," she said with a drunken giggle.

"Where?"

"The girls for a start."

"I'll let you take care of them."

"Spoilsport," she sniggered.

She was definitely hammered. Then pinching each nipple between a thumb and forefinger, she lifted up her breasts.

"Don't forget to dry underneath," she announced.

Hesitantly and very gently I patted her under boobage dry.

"You can be firmer you know," she chastised. "They won't bite." Another drunken giggle followed.

Taking the bull by the horns I dried them. She released her grip on them and I was left holding them and feeling their softness and realizing my cock was getting stiffer. I tried not to spend too long squeezing them as I dried them and I had to focus hard on letting them go.

"You forgot to dry my thighs and the lady garden too. If you're going to do the job do it right," she sniggered.

Was she enjoying my humiliation? Or was she enjoying the thrill of her brother's hand roaming all over her body? The sad thing was that I was starting to enjoy it even though my inner self was in conflict.

Hunkering down in front of her I tentatively started to dry her upper thighs. Did I hear her moan as I dried? Then up onto her thick thatch of hair. I was getting braver now and dried harder.

"Don't forget in there?" she said as she pointed to her pussy.

"Just because it has lips doesn't mean it will bite," she said with yet another drunken giggle.

Then spreading her legs further, she rubbed her pussy as if to check if it was dry, then using both hands pulled her pussy lips open exposing her aroused and hard clit poking out from beneath its glistening hood.

"How does the little lady look?" she asked me.

I'd never heard of a clit being to referred to like that.

"Does she look good?"

"She certainly does," I replied and I wasn't lying either. It looked great and my now stiff cock liked it too.

Will she remember this behaviour in the morning?

How will she react if she does?

Will our new found closeness suffer?

I hoped not.

Although another line had been crossed this evening; it was excusable. Wasn't it? She's drunk and doesn't realize what she's doing. We'll be fine.

"Come on John. Get drying," she said as she spread her legs further giving me access to her wondrous pussy.

I rubbed the left side of her pussy a few times before changing hands and rubbing the other side. As I did, she let out another soft moan and I could smell her arousal. That made my cock rock hard to the point of being sore. It hasn't been that hard for a while. I was petrified she'd see it and then start touching it. While my sex head was secretly hoping she would, my real head was getting scared. Things were getting beyond my comfort zone.

"Let's get you to bed so I can sort the dishes and get to bed too. You'll have to share with me as your old bed isn't ready. I wasn't expecting you today"

She allowed me to guide her to my bed and I was careful not to poke her with my stiffy. Once she was in bed, she fell into a sound sleep. I went back into the kitchen and tidied up. My stiffy wasn't fading any and the memories of this evening weren't helping. I couldn't wait to have a shower and a wank.

Once under the hot water I started to stroke my rigid cock. It has been a long time since I'd been this hard. Touching it was almost painful. Slowly I replayed all that had happened. Her stiff nipples pressing into me as she fell against me getting out of the tub and then her thigh rubbing against my cock. I could feel my balls begin to tingle.

Then the feel of her body through the towel as I dried her. The softness of her ass cheeks. The firmness of her boobs and the feel of her stiff nipples against my fingers. The soft skin of her upper thighs and the feel of her pubic hair. The smell of her arousal.

The tingling was now in overdrive and my stroking had increased. My cock was beginning to ache from the stiffness. Why wasn't I already cumming?

Then my orgasm exploded and washed over me. My knees gave way and I slumped against the wall. Ropes of cum erupted from my cock. It was an amazing sensation. It felt like there were fireworks going off in my head.

Finally, I stopped cumming and as I ran my fingertip across my slit to wipe off a cum droplet, I winced. It was very sensitive.

I sank to the shower floor and sat for a while as I waited for my heart rate and breathing to return to normal. The hot water splashing over me didn't help but I was too exhausted to stand up and turn it off. What an orgasm!!

Slowly, I got to my feet and finished my shower before washing the cum off the shower door. Then stepping out I got dried and went to bed.

The next thing I remember is wakening up the next morning. It took a few seconds to realize what was happening. I was lying on my back and Gwen was snuggled into me. Her left arm was across my chest and her left leg was across my tummy, placing her left thigh against my morning erection.

"Oh shit," I thought. "I don't need anymore arousal after last night."

Suddenly the memories of the previous evening came flooding back again ending with my massive orgasm in the shower. Those memories, along with the body heat from my sleeping sister and the feel of her leg against my cock was getting out of control. My real head was telling me to get out before I came all over her. I obeyed.

Carefully I slipped out. She was so sound asleep, she didn't rouse.

It was 9a.m. I put on a top and shorts then went into the kitchen to make breakfast. By 10a.m. I was wondering if I should waken her or let her sleep when she stepped out of the bedroom looking rough and holding her head in her hands. Her robe wasn't tied and gaped open revealing the breasts I had been drying the previous evening. A view I don't think I'll ever get tired of.

"Good morning sis," I said.

Screwing up her eyes she looked over at me and said, "Not so loud please."

I laughed. She was suffering.

"Sit down and I'll get you some water and paracetamol."

I was tempted to ask if she wanted some fried eggs and bacon for breakfast to watch her reaction, but thought that would be too cruel. Instead I filled a glass with water and got some paracetamol for her, no doubt, thumping head. Placing them in front of her, I ordered her to drink.

"What happened?" she croaked.

"You went a bit mad on the beer and the hot tub didn't help."

"I'm sorry John."

"What for?"

"Spoiling your evening."

"You didn't spoil it," I said.

"In fact," I thought to myself, "you made my evening."

But I daren't tell her that. What surprised me was my lack of guilt over what had happened. But then, I didn't really do anything wrong. All I did was dry her and put her to bed. Ok, I enjoyed it and had one of the best orgasms I'd ever experienced and probably ever would again; but I didn't do anything wrong.

"Are you sure? Or are you just saying that to make me happy?"

"I'm very much sure. You didn't spoil my evening."

She gave me a weak smile. She was truly suffering, poor girl.

"Think I'll have a shower and see if it will waken me up."

"I'll have a coffee ready for you when you're finished."

"Thanks bro."

Then off she went to the shower.

I had her coffee ready when she returned and she was looking a bit more human.

"How do you feel?" I asked.

"Better," she said.

"Would you like something to eat? Some toast maybe?"

"Thanks. That would be nice."

As I prepared the toast, she put her head down onto the table and groaned.

"How's your head?" I asked.

"Like it's split open," she groaned, "and being hit with a sledgehammer."

I buttered the toast, put it on a plate and set it in front of her.

"Thank you," she said and started eating.

"Did I behave myself last night?" she enquired.

"What do you mean?"

"I didn't say or do anything embarrassing?"

"No, you didn't," I lied. I wasn't going to cause her any guilt by reminding her that she basically got me to feel her up by drying her or that she exposed her clit to me. Ignorance would be bliss.

"Are you sure?"

"Yes, I'm sure and before you ask again; no, you didn't spoil my evening."

"I know now I mustn't have," she said giving me a wink and grinning broadly.

Now I was confused.

"Oh," I said, "you believe me now?"

"Yes."

"That's good."

"Don't you want to know why?"

"Ok, tell me."

"You didn't make a great job of rinsing down the shower door."

Slowly the penny dropped.

"I didn't?"

"No and it was right at the top of the door. Somebody had a powerful...eruption," she said with a smirk.

I laughed. There was nothing else I could do. I'd been busted. Gwen laughed too.

"Seriously, it was right at the top of the door. You must have had one major orgasm," she giggled.

"I did and no point denying it."

"Are they always that strong?"

"Well, no. It had just been a while."

Was I really discussing orgasms and cumming with my sister?

"Did I do anything to bring it on?"

"Oh dear," I thought. "Do I lie or tell the truth?"

"Not really," I said as a half lie.

"What does 'not really' mean?"

"You were naked. You have a great body and although you're my sister, I'm male

so I react. You've seen it happen before."

"I didn't do anything else then?"

"No," I lied again.

She smiled as if she had been re-assured she had not over-stepped the mark.

"Ok, I'll need to get sorted and get home. I've lots to get done today. Thank you for last night. For listening and keeping me company. I really appreciate it."

"My pleasure sis. It's what big brothers do."
