I was sitting watching a baseball game with my cousin Will in his living room one summer. It was the tradition for Will and his little sister Heidi to spend a couple of weeks at our house and then for us to spend two weeks at their house. It was our second day at Will's when we heard the stereo turn on in Heidi's room and someone crank it up full blast.
Will turned the tv up and we kept watching the baseball game but I could tell that the noise was really bothering him. He had a thing for his little sister and I couldn't blame him. She and my sister were almost identical. Medium height, very thin with small breasts, long white-blonde hair and gorgeous green eyes.
I've been wanting to fuck my sister for as long as I can remember, and I'd probably admit it to most people, but Will was ashamed of the fact that he wanted to fuck his own sister. He'd never admitted it to anyone, me included. He even mostly denied it to himself. But he saw his sexy sister all the time and all of that desire had to go somewhere. Generally it turned into anger, it never took him long to get totally pissed off at Heidi for being a regular teenage girl.
This time was no different. He finally tossed the remote control down and stormed off upstairs to confront his sister in a rage of sexual frustration. I waited around in the living room. He was gone for awhile and when he got back the stereo was still blaring.
"Hey, Jake," he said, "it looks like our little sisters are taking a page out of our book."
"What?" I asked, wondering what in the hell he was talking about.
"They're up there getting off together," he answered.
"Shit!" I said and jumped up off the couch. I couldn't believe that our little sisters were up there playing with their pussies together.
"Yeah," Will said, "the door's locked but I can hear them in there. I bet we can pick the lock."
I followed Will upstairs to Heidi's bedroom and we listened to their moans for awhile. Then we got a hairpin from the bathroom and went to pick the lock. It was a hopeless situation. The hairpin was too weak and we were just way too turned on to get anything done. Will was like an animal in a trap, chewing it's own leg off to escape. I knew that he was so intent on getting into that bedroom and getting at his little sister's young cunt that he wasn't thinking straight. He'd just keep trying to pick the lock when what he needed to do was shoot a load, calm down and think straight.
I took the situation into my own hands and said, "Shit, I can't take this anymore."
Will looked up and I pulled my hard cock out of my shorts. I started pounding my cock and I watched Will drop his shorts and start doing the same. The sight of Will's cock always turned me on. We'd been jacking off together since we started getting hardons and it didn't take us long to move on to handjobs and blowjobs. I'd gotten really good at getting my load off fast so that I would have time to finish up Will's cock for him.
Today was no different. I came hard and fast, shooting globs of white cum all over Heidi's bedroom door. I turned to Will and took his hot delicious cock into my mouth. He started moaning and I sucked as hard as I could, knowing that this was a special day for him.
I don't think Will knows that I'm bi. We've been getting each other off for so long Will has come to rationalize what we do. What's the difference between one mouth or another? One hand or another? I knew that he felt that we had started young, too young to realize that what we were doing was considered "gay". And since we had been doing it for so long and it felt so damned good, why stop? I knew that Will didn't find other guys attractive the way that he found girls attractive. But I'd also seen the way he looked at my hard cock, he liked the feel of it in his hand and the taste of it in his mouth. He may be straight but he certainly enjoyed cock, whether he admitted it to himself or not.
I could tell from experience that Will was about to cum and I took his cock out of my mouth so that he could shoot his load all over his sister's door just as I had done. I watched him looking at the cum stained door and smiling. He was marking his territory, claiming his little sister as his own, admitting to himself that he was going to go in there and fuck his own sister, whether she wanted it or not.
We listened as the moans in the bedroom turned to screams of passion. The sound went right through me, I wanted to ram my cock into the girl who was screaming like that and make her scream for me. I looked at Will and said, "Fuck, we have got to get in there. I am going to shove my cock into whoever is screaming like that."
