Along with my twin sister Carol, I'd been 'farmed out' to stay with my Aunt Sarah during the summer holidays. It wasn't anybody's fault, it was just that my grandfather was terminally ill and our parents had gone to look after him for his last few weeks just as the university year ended. It was one of those things and my sadness for grandpa overruled any complaints I might have had, but there are better ways of spending the summer. Much as I could get along with Aunt Sarah and my cousin's Ruth and Kyle, I wasn't over happy about having to share a room with Kyle. He was ok, but I'd been sharing a room at Uni and I'd been looking forward to having my own space. Having said all that, the way things were going it looked as though it was going to be quite an interesting summer.
It was the end of our third day there and Kyle and I were lying in our separate beds watching the end of a TV film before going to sleep. It wasn't a particularly good film, just really an excuse for staying awake a little longer, and so when the closing credits began to roll I didn't have much of an idea about who had finally been revealed as the murderer. I'd been too busy thinking about my sister and the mutual masturbation session that the three of us had enjoyed a couple of days previously. I couldn't stop wondering if she and I would have gone all the way and fucked if Kyle hadn't been present. As it was she had wanked him off and given me a blow job before we made her cum by hand, and I was pretty sure she was up for a shag too. I was also wondering why that never would have happened if we'd been at home.
Kyle pointed the remote at the box and flicked it off.
"Would you have fucked Caz if she'd let you?"
His sudden question caught me by surprise, but it told me where his thoughts had been as well. I pretended to have to think about it, more for appearances sake than anything else, but it did give me time to phrase an answer.
"I'm not sure." I began. "But I think probably so, yes. After all she's not bad looking for a sister and it's not easy to turn a good fuck down, is it? Anyway, would you have?"
His answer was surprisingly direct. "Yes. Anytime she liked. But I couldn't do anything with her brother there, could I?"
It seemed we'd got in each other's way! I wondered what if the boot had been on the other foot.
"And if it had been Ruth? Would you then?"
"I think Ruth is more likely to go with Chloe than either of us." He ducked the question smartly and I drew my own conclusions.
Chloe was Ruth's friend who was staying over for the holidays. The two girls were sharing Ruth's bedroom and everyone had a good idea why. A shame actually, because Chloe would really have been worth the effort - and so would Ruth for that matter.
I reached under the duvet to make necessary adjustments. I usually slept in pair of shorts, but Kyle slept naked and it had seemed a bit timid of me not to do the same. My cock wasn't used to so much freedom and reacted to our conversation more readily than normal. Or at least, that's what I told myself.
We lapsed into silence and I turned the events of that day over in my mind once again. I still felt a bit uneasy about it, even though I'd enjoyed it at the time.
"I tell you what." I said eventually, just to break the stillness. "That was quite a session. Not something I expected to happen, did you?"
"Never in a million years." Kyle looked at me hard. "Were you really trying to get your fist up her cunt?"
"Well, yes! That's what she asked me to do, wasn't it? And I nearly did it. If she hadn't cum just then I think it would have gone in." Carol had told me she wanted as many fingers up her as I could get, and even my whole hand if it would go. As it happened it didn't go, but I got pretty close.
"Didn't she make a lot of fucking noise, though?" Kyle reminded me about Carol's noisy orgasm
"If anyone else had been in the house...." He let it trail off, and then, looking at me, he burst out laughing.
"You've got a stiffy." He pointed at my duvet. "You've got a stiffy from thinking about fucking your sister."
I didn't argue, although thinking about fucking Chloe had been what they call a contributory factor. Instead I just looked hard at the little pyramid in his bedclothes.
"And you've got one from thinking about fucking your cousin."
I don't think Kyle had realised that he too had an erection, because my answer seemed to catch him unawares.
"Ooops! So I have." He laughed back as he investigated his cock.
"I wonder which of us is biggest today from thinking about Caz." He mused. "Because whoever's hardest fancies her most, don't they?"
"Oh, no. I'm not getting into that again." It had been a cock size contest that had started things two days before. "But I think you fancy her enough for us both judging by the lump in your duvet."
To my surprise Kyle promptly threw back his duvet to reveal his erection, hard and red, sticking straight up. "Can you match that?" He asked, grinning.
I didn't really want to, but I couldn't let him get away with it, so I pushed my duvet out of the way and showed him my own cock, equally hard and equally hot.
"Wow! Horny pair of sods, aren't we." Kyle looked genuinely surprised at how turned on I was, and if truth be told, so was I. I really needed a fuck, or at least a wank, but it would have to wait.
Kyle went back to the original subject. "Would you mind if I fucked your sister? You can watch if you want!"
