I must have drifted back to sleep though, because when I woke it was after nine. I slipped out of bed and went to the kitchen, turned the coffee machine on and made myself a cappuccino. I wandered out by the pool and sat at the table enjoying my coffee. It was a perfect summers day, warm with a cloudless blue sky.
I was having difficulty concentrating, and kept asking myself how Rebecca’s and my relationship might change. I mean, yesterday she was my twin sister and today she’s my lover. And with our parents coming home tomorrow, I had no idea how we could continue with our relationship. I went upstairs and changed into my Speedos and returned to the pool, settling onto a sun bed.
I was really quite confused, I resented the fact Bec wasn’t with me and was spending time with her girlfriend Carly. I was extremely jealous.
I must have dozed again because when I looked up Bec was standing beside me at the pools edge.
“Hi Sis, what time is it?” I asked.
“Two thirty,” Bec said.
“I must have slept, you’re back early aren’t you?”
Bec pulled a sun bed next to mine and sat beside me. “It’s strange Tony, I couldn’t get you off my mind today,” she said, “I couldn’t concentrate on anything much.”
“Tell me about it,” I replied.
We sat for a few moments in silence before she said, “Amongst other things, I can’t stop thinking about what you said this morning, about jerking yourself off after watching me pee. What is that all about?”
“I don’t know, I just found the sight of you peeing a real turn on.”
“You weren’t supposed to be looking, mum told you to look the other way if I remember correctly.” Bec said.
Jesus Sis, it was too much of a temptation; the chance to get a look at my sisters snatch. Watching that stream of pee coming from your beautiful fanny and splashing on the grass. I got a hard on straight away. I’ve never forgotten that and I never will.”
“It’s sort of weird don’t you think?”
“Well surely you fantasise about things when you masturbate?” I asked.
“Well, I’ve never really thought about something like that. I’ve never thought of peeing as being sexy,” Bec replied.
“I can’t help it, ever since then I’ve found the thought of you pissing a real turn on.”
“So how do I fit in, how do you include me?” Bec asked.
“I imagine you crouching over me where I can see all your girly bits, and when I’m about to cum I get you to pee all over my cock and balls.”
I was rock hard again now and made no attempt to hide it from Bec. My cock was straining against my nylon Speedos. Bec reached over and gave it a squeeze.
“I’m going to get changed brother dear, so don’t go away or you might miss something special,” Bec added with a cheeky smile.
She disappeared inside and I wondered what she had in mind. My heart was pounding with anticipation.
Soon Bec reappeared, completely naked with a large beach towel and a pillow from the lounge. She spread them on the ground by the pool just out of the sun.
“I need to pee Tony,” she said.
“You fucking serious,” I asked, “you’d actually do this for me?”
“I really do need to pee Baby so come over and lie down.”
I stood, slipped out of my swimmers and shirt and lay on the towel. I thought to myself I can’t believe my luck, one of my wildest fantasies is about to come true.
Bec positioned herself over my groin. As she stood smiling down at me, I had a perfect view of her slit and beautiful tits. The sight of her standing over me, stark naked, made me more desperate than ever to relieve the tension in my balls. I’d never needed to masturbate so badly in my life.
“It’s funny, but as I said, I didn’t think peeing could be such a turn on, but actually doing this with you, well maybe I was wrong,” she said, “but you’d better get started brother dear or I’ll piss myself before you’re ready,” she said with a smile.
“Jesus Bec, it won’t take me long to cum, I’m hornier than ever.”
I started my familiar rhythmical stroke, slowly at first but my desperate need to cum, quickly drove me to vigorous stroking. The need to release my seed was intense.
Bec recognised the signs I was getting close, so she crouched and positioned her pussy just above my cock. Her legs were spread wide and her cunt lips were swollen and red with arousal. I could see her clit, poking from its hood of skin, her vagina was wide open. This is insane I thought to myself.
Stroking faster I said, “Now Sis, please start peeing on me, I’m gonna cum.”
The first flow was more of a dribble than a stream, but it felt wonderful and warm as it splashed onto my hand and cock as I stroked. Bec readjusted herself slightly as the stream of urine intensified and hit me with some force.
“Oh God,” I moaned, “Here it is Sis!”
I threw my head back in ecstasy as I began ejaculating my creamy white lava into her pale yellow stream of piss. Time seemed to stand still as the pleasure engulfed me. There was no doubt in my mind the sight of Bec peeing on me was the sexiest thing I’d ever seen. I watched in awe as it splashed onto my semen soaked cock and trickled onto my tummy, down my sides and between my legs.
“Oh wow,” Bec said, “I can’t believe we actually did that, I really enjoyed it.”
“What was it you enjoyed,” I said with a laugh, “relieving yourself?”
“You’re a prick Tony, you know what I meant.”
The fact is, I was drenched with a mixture of Bec’s urine and my semen and I loved the sensation.
“What about returning the favour?” she asked.
“You want me to …?”
Bec cut me off, “I’d love you to do it with me Tony, I’m so hot.”
We changed places and Bec lay on the towel with her legs spread wide. I usually needed to pee immediately after masturbating so I kneeled between her legs holding my softening penis inches from her open slit. Bec placed her hand onto her vulva and using her fingers began vigorously massaging her swollen clit. My head was swimming as it suddenly dawned on me I was about to piss on my beautiful sister.
“Get ready Tony, I’m going to cum,” she moaned “Oh let it go Tony, piss on me now, piss onto my cunt.”
I started slowly, directing my aim at her cunt as she flailed at her pussy to bring her orgasm on. Just as my stream steadied she groaned, eyes staring, mouth open as her orgasm began.
“Oh fuck, fuck, fuck …” she grunted as she became lost in her pleasure. I watched in awe as her cunt convulsed violently with orgasmic contractions. All the while I kept pissing onto her open cunt until my bladder finally emptied.
I flopped down beside her and neither of us moved or spoke for some time as we recovered our composure. I could feel the towel, wet through with our bodily fluids.
“That was just amazing!” she said.
“I know, but what a mess. We should have a swim and clean up,” I said.
We jumped into the pool and swam around for twenty minutes or so before getting out and rinsing off under the outdoor shower. We didn’t say a word, we were both coming to terms with what had happened.
After drying off we went into the house, still naked and fell into the leather lounge in the family room. I couldn’t stop thinking how few girls would be prepared to indulge in something as kinky as a golden shower. No doubt about it, I was deeply in love with my sister.
We lay in each other’s arms, bare skin against bare skin, fondling and cuddling. We were totally relaxed in a state of post sex euphoria.
Finally I broke the silence and asked.”Want to see the rest of that movie from last night?”
“Nah, I couldn’t be bothered although if I remember correctly, that’s what set things off with us. Besides I can think of better things to do.
“Do you realise too that mum and dad will be home tomorrow afternoon. Have you thought about that?” she said.
“Yes, it will make things a tad tricky that’s for sure.”
Bec said, “It will but I think we’ll be able to manage to find time together, don’t you?”
“I hope so, I’ll work on it,” I said.
At around six thirty the doorbell rang and we both raced to get some clothes on. It was the pizza delivery guy and we certainly couldn’t answer the door naked. When we’d finished dinner we sat listening to music and relaxed on the lounge. We talked about the things we’d enjoyed and the subject moved to our sexual fantasies.
Bec asked me what other things I thought about when I jerked off and I described some of my favourite fantasies. I explained that most of my fantasies included masturbation because it was what I was about to do. My favourite was the golden shower but I also enjoyed fantasising about two girls making out. Rebecca nodded then went on to share a few of her fantasies. The thing that really struck me was how similar they were.
After a while our conversation moved on and I asked her if she’d ever had one of those really embarrassing moments.
She laughed and said, “Yeah, mum bought me a Magic Wand vibrator for my sixteenth birthday. That was embarrassing enough but I made the mistake of really giving it a workout that night in bed. I used it for hours and experienced more orgasms that I can remember.
“The problem was, the following day my fanny was red raw, I could barely walk. I told mum what I’d done and she just laughed and said ‘let that be a lesson to you in moderation’.
“She gave me some cream to rub on my raw fanny and I couldn’t touch myself down there for quite a few days.
“That was probably the most embarrassing moment in my life I guess.”
“Wow,” I said, “do you still use it now?”
“Yes most of the time, it gets me off easier and quicker,” she added “What was your most embarrassing moment?”
“Strangely it included mum too and it was the worst day of my life,” I said, “It was a Wednesday afternoon and it was pissing down rain. Sport was cancelled that day at school so I came home with Denny.
“Mum and dad were at work and you were at school, so one thing led to another and Denny and I started to play around a bit.
“We were on my bed and Denny was … Umm, well he was sucking me off. Unfortunately for us, this was the only time in living memory that mum came home from work early.
“My bedroom door was open because I wasn’t expecting anyone for hours but mum walked past the room and saw us.”
“Oh shit, Bec said, “what happened, what did she do?”
“She ah, just pulled the door shut and didn’t say a thing which freaked us out even more I reckon.”
“Poor Denny was afraid to leave, he couldn’t face mum, but I sneaked him out the back way. It was just awful.”
“Did she say anything later?” Bec asked.
“Yeah, I tried to keep out of her way but the following day she came in and sat on my bed and asked if we could have a chat. I was freaking out because I knew what was coming.
“As it turned out it wasn’t all that bad because she said what Denny and I were doing was a completely natural part of sexual experimentation for a teenager. Her only complaint was that we were really indiscrete by leaving my door open. She actually said she’d done things with a girlfriend when she was a teenager too.”
“That’s pretty cool don’t you think? Bec said.
“Um, yep,” I agreed.
“Based on the things she said, what do you think the oldies would say if they knew about us?”
“Hard to say I reckon, but I really don’t want to find out,” I added.
“So do you still make out with Denny?”
“Nah, somehow we got too old and mature for that sort of thing. Shame in a way.” I said flashing a smile at her.
“I get horny thinking about Denny sucking your dick,” she said.
“Yeah, well I get horny thinking about you and Carly together too.”
It was almost nine so Bec asked if I wanted to go up to bed and fool around. On the way we decided to shower together so went to our bathroom. We were both very horny and couldn’t keep our hands off each other. At one stage I had Bec bend over and fucked her furiously from behind. It was sensational fucking her with the warm water pouring over us, but even though Bec desperately wanted me to cum in her, I resisted because I wanted to relish out time in bed.
Afterwards, we went to my room and fucked for an hour or more, slowly at first and finished in an orgasmic frenzy. It was sensational sex.
Then out of the blue Bec said, “I’ve got something to tell you.”
“What’s that?”
“You’re not going to like it,” she said.
“Go on,”
“Carly knows about us.”
“What?”
“She knows about you and me,” she said.
“You’re fucking kidding Bec,” I said, “you can’t be fucking serious. I mean what did you tell her?”
“Well, nothing and everything,” Bec said, “I’m not sure how she knew, but she sort of guessed something was going on. I don’t know if it was something I said or maybe even the way I was acting. I was off with the pixies this morning.”
“So what did you tell her?”
“Just that we’d made love.”
“What did she say?”
“She basically said, ‘lucky you Bec, I’m jealous’.”
“What?” I asked, “what does that mean?”
“It means she wants to fuck you too,” she said, “I’ve never told you this but she’s often said what a spunk you are and how much she’d like to fuck you.”
“She said she’d like to fuck me? You’re kidding!” I said.
“It always made me angry when she talked like that. I mean you’re my brother and I didn’t like it. How would you like it if your mates said they’d like to fuck me?”
“Well, that happens Sis,” I said, “I’ve been around when plenty of guys have said they’d like to screw you.”
“How did you feel about that?”
“Yeah, a bit pissed I guess. But what about Carly, what are we going to do? If she says something we could be in deep shit.”
“Well, she asked if she could come over in the morning and I wasn’t really happy about it at first because I don’t want her fucking around with you.”
“Now you sound jealous,” I said “it might be fun Baby.”
“Fuck you!”
We both laughed.
“But in a way it might be a good thing. I think if we were to spend some time with her, sort of keeping her happy if you get my drift, everything should be fine. She really wouldn’t be able to say anything to anyone.”
“Let’s hope so,” I added, while contemplating what it would be like to experience a threesome with my sister and one of the hottest chicks in the neighbourhood.
