Thomas and Holly had been joining us in the bedroom for over a year. Both children appeared to enjoy their 'sex life' very much. Holly said she liked it because it was a bit 'naughty'. Thomas said that it made him feel very 'grown up', especially as his mates at school didn't get to do what he did with their parents.
Needless to say that Sue and I quite enjoyed their participation too! I loved the fact that while both children had learned a great deal about sex, neither of them quite understood why they were doing it. Sue was turned on by the idea of the children watching us while we had sex. She also quite enjoyed the fact that her husband liked little girls.
It was a typical Saturday evening. Sue and I were having sex and the children were watching. Sue was straddling me, my prick buried deep inside her vagina. Tom and Holly were naked and kneeling next to us, taking it all in. As usual when Sue was on top, I used one hand to play with her tits while the other was situated between her bum cheeks, my index finger inserted inside her anus. Sue was doing all the work, bouncing up and down with her hands on my chest.
"Holly." said Sue, stopping her bouncing. "Can you see where Duncan's got his hand?"
"It's on your boobs!" Holly said, giggling.
"No, the other one!" Sue said.
"It's on your bum!" the 8 year old replied, still giggling.
"Can you see where his finger is?" Sue continued. Holly lent across her stepbrother and lowered her head to take a closer look.
"Is it IN your bum?" she asked.
"Yes, and it's a beautiful feeling. Would you like Thomas to put his finger in YOUR bum?" Sue asked her daughter.
"I'm not sure, mum. Will it hurt me?" asked Holly a little nervously.
"No, don't worry, it won't hurt." her mum reassured her. "Thomas, would you like to try putting your finger inside Holly's bottom?" Sue said.
"Yeah, OK." he said, after carefully considering the proposal.
Sue told Holly to get on to all fours and stick her bum in the air. God, it was beautiful.
"Hold your checks apart" her mum told her. "When you feel Thomas' finger on your bottom, push, like you're trying to do a poo. That'll make it slide in much easier." Sue explained.
"Tom, lick your index finger." I told him.
"Why?" he asked, looking puzzled. I explained that it would help it slip in more easily and I watched as he gave his right index finger a liberal coating of saliva before holding it ready at Holly's anus.
"OK, now, VERY GENTLY push it in." I told him.
"Holly, push like you're doing a poo." Sue reminded her daughter, as Tom wiggled his digit around the entrance to her tight pink preteen passage.
Thomas' finger made a successful entry. "How's that feel, Holly?" asked her mum.
"Oooo.........it's OK, I think." the little one replied.
"How about you Tom?" I asked.. My son informed us that it felt very tight. His rising penis told its own story. But he had less than an inch of finger inside her bum.
"Try to push it in a bit further." I told him.
"Arrrghhhh......that hurts!" cried Holly, as Tom tried to force another inch of finger up inside her delicate nether regions.
"I told you to PUSH when you felt it going in, didn't I, Holly?" Sue said, shaking her head.
"I WAS pushing, mum!" her daughter insisted.
With a little coaxing and a lot of patience, we managed to get most of Tom's finger up inside Holly's rectum. We decided that that was probably quite enough for her first time and we told Tom he could remove his finger. Pulling it out, he looked relieved to find that it appeared to have suffered no ill effects from its journey inside his stepsister's back passage.
Sue resumed her bouncing. The sight of Holly with my son's finger inside her little bum had almost pushed me over the edge. I gripped Sue's hips, and we began moving in unison towards climax.
"Oh God! Sue...I'm cuming! I cried, as my penis spasmed inside my wife's pussy, her muscles milking every last drop of sperm from it. Pulling her to me, I kissed her passionately on the lips, my prick gradually softening inside her.
"Duncan, I think I need a wee." Sue said.
"OK" I said, reluctantly releasing her from my embrace. Suddenly, I felt warm liquid flooding over my crotch and realised that Sue had no plans to visit the loo!
"Mum! You're weeing on him!" cried Holly, drawing in her breath rapidly and elbowing her stepbrother to draw his attention to what her mum was doing. Sue's piss was soaking my balls and running down my thighs. My eyes were fixed on her tiny pee hole, as her bladder emptied its golden contents over me - and the bed.
After about 20 seconds, her stream gradually came to a end and the room fell silent.
"Mum, did you wet yourself?" asked Holly.
"No, darling, It's just a long way to the loo." Sue said smiling at her young daughter.
"But you can't do your wee in bed!" insisted the incredulous youngster.
"You can if you use a plastic sheet." said her mum. Feeling the mattress, I realised that my wife had planned her little 'accident'.
"Do you need to go?" Sue asked me.
"Why?" I said.
"You can go inside me." she whispered. I checked to see if I had any urge to urinate, but sadly I had to tell her that I hadn't any to do.
"Never mind." she said, "Next time."
"Holly, do you need a wee?" she asked her daughter. The little girl thought for a moment.
"Yes, I do need to go." she said. My prick had softened inside Sue but the though of Holly needing a wee made it twitch into life again.
"Shall we go to the bathroom then?" Sue said. Easing herself off of me, she got up and handed me a towel. I dried myself off and the four of us headed for the bathroom.
"Shall I sit on the loo, mum?" Holly asked.
"No, I'd like you to do it in the bath, please.Thomas, can you get in first, please, then Holly can squat over you." I couldn't believe that the children were so willing to participate in a session of watersports, but Thomas was already eagerly stepping into the bath. We told him to lay down, then Sue helped Holly climb in, getting her to stand with one leg either side of her stepbrother.
"OK, young lady, can you squat please." said her mother. Down she went until her bum was hovering over Tom's stomach, Sue adjusted Holly's position so that she was squatting was just below Tom's crotch.
"How much wee have you got to do?" Sue asked the 8 year old.
"Quite a bit, I think." her daughter replied.
"I want you to spray it over his willy and balls." Sue told the excited youngster.
Tom's penis had decided to give the little girl a bigger target to aim for. All evening, it had either been soft or semi erect, but now it stood up like a stiff little soldier on parade.
"Shall I start, mum?" Holly asked..
"Wait a minute please." said Sue.
"Duncan, why don't you kneel down so you can see better." Sue said to me, and I positioned myself by the side of the tub, a little in front of her daughter. From there I was able to look between her thighs and enjoy the same view as my son. Sue knelt beside me. Three pairs of eyes were now on Holly's sweet little hairless vulva, all waiting for her to do what came naturally.
The bathroom fell silent. The only sound was Holly's breathing, as she concentrated on getting her stream started. After a minute the little girl looked at her mum and told her that it wouldn't come.
"Close your eyes and relax - then it'll come. Imagine you're sitting on the loo." said her mum.. The little one did as her mother suggested and finally a little trickle of urine fell from her and ran down the gap between Tom's thighs.
My penis had been erect ever since the idea of watching Holly pee was suggested and I couldn't help but start wanking. Then Holly's proper stream began. The little girl was right - she DID have quite a lot of wee to do - I estimated nearly a pint. It came out with a little hiss, splashing over Tom's genitals.
"Arrgghh....Sue, I'm cuming again!" I said, rubbing my prick furiously. My wife was just in time to see the first spurt of spunk shoot out and hit the side of the bath. I continued to pump sperm out as I watched Holly bathe Tom's 4 inch erection and tiny testicles with her wee wee. She looked like a little princess of pee, as her 8 year old bladder gradually drained its golden contents over my son's naked body.
After about half a minute, her stream slowed to a trickle and she plonked down her bum on her pee partner and looked at me and Sue.
"Was that OK, mum?"
"Very very very very good, darling." Sue praised her.
"That was amazing, Holly." I added, still gently massaging my softening penis out of her view.
"Holly, you're squashing me!" Tom complained, "Sorry." the little girl said, raising her bottom a little.
"Right, let's get you two cleaned up." said Sue, and with the children standing, she used the shower attachment to rinse them off. One at a time we got them out, dried them off and put them in their dressing gowns.
"Dad, can I do my wee on Holly?" Tom asked me as we went downstairs.
"You can, if Holly wants you to, but not tonight. It's nearly bedtime." I told him. Having shot out 2 lots of sperm that evening, I didn't think I could do justice to a third. Besides, I wanted something to look forward to for another day.
The reviewing period for this story has ended.
