Brother in Law's Cock

I was fixing my brother in law Michael's computer for him one day when I stumbled across what became clear in the first seconds was a sex tape he had made of him and his wife. It was like a dream come true. I'd had the hots for Heather for years, and I'd always dreamed of seeing her naked. Here was the chance. And sure enough, as the tape got going, she started to strip. She was really fucking hot, pierced nips and a totally smooth pussy just begging for attention.

But she was going to give some attention first. The video cam was set down on the dresser in their room and Heather, now totally naked, started to pull off Michael's boxers.

When she did, I was totally shocked. Michael was fucking huge! Ten inches and really thick. Cut, and when hard pointed up toward his chin! Heather then proceeded to do things to him I don't think I'm supposed to mention here, and you could tell it was a bit of a struggle, because he was so big.

I didn't feel the least bit guilty, by the way, for violating their privacy, since I'd found out that Michael had done the same thing to me and my wife on a few occasions (though I never confronted him).

As I watched, I pulled out my cock, a nice 7 incher that's pretty thick itself. But it seemed downright small compared to Michael's! Which didn't stop me from stroking it, coming over the course of an hour and a half not once but twice to this amazing tape.

Afterward the strangest thing happened. I found myself jerking off thinking not about Heather but about Michael! Well, not about Michael as much as about Michael's amazing cock. At first this surprised me, because although I've been sort of curious about guys over the years, I've never specifically fantasized about any one person. And here I was thinking about my brother in law!

Even worse, I wanted to make something happen. So I devised a plan, which wasn't much more than me tricking him into doing what I'd wanted to do since I saw the tape.

Both the wives were working and we were alone at my place when the subject of sex somehow came up. (It was me, I admit and the fact we were watching porn.) I worked about the subject to cock size and made the statement that most guys exaggerate the size of their cocks. They all, I said, claimed to be a lot bigger than they are. Michael looked a little offended and said that he doesn't do that.

I then proceeded to tell him that it was okay, that I didn't mean to offend him, that some guys are just smaller than average and that there's nothing wrong with it. They can make up for it in other ways, I said.

Michael took the bait, telling me that such was not his problem, that he was big. How big? I asked. Porn star sized, he said. Well, that played right into my hands. I told him that this was the point I was making right at first, that guys greatly exaggerate their size. There was no way he had any kind of cock that resembled a porn star's, and I asked him to 'prove it.'

Well, he wasn't gay, he told me, and I told him that I wasn't either. It was simply a case of him showing me so we could decide which one of us was right and which was wrong.

Of course, the fact that I knew I was wrong didn't come up. I just wanted to see and get my hands (and maybe more) on his giant cock.

Michael looked resigned, sat himself, and very matter of factly slipped his shorts and underwear down to his thighs.

He wasn't hard, and he was actually fairly modest looking when soft, which, again, played right into my hand. I chuckled at him and said that it proved my point. He said no way, that he needed to get hard and set about stroking himself right in front of me, his worries about appearing gay apparently forgotten.

'As if that will help,' I told him, and went off to get the lube. I was back in half a minute and Michael still wasn't very hard, though he was bigger. I motioned him to move his hand away and dribbled the lube onto his cock. 'Let me help you,' I said, and proceeded to lube up his cock. Michael started to voice some words of concern but, lost in the moment, put his head back and let me do my stuff.

It was the first time I'd ever had somebody else's cock in my hand, and it was amazing. As I stroked him, it did indeed start to grow, stroke by stroke expanding to the mammoth proportions I'd seen on the homemade sex tape.

It was, just as I'd guessed, at least ten inches in length and just thick enough to match its length without being freakishly girthy. It was, in short, a perfect cock. And it was mine, at least right then.

As I stroked Michael's huge cock, his hips started to rock, signaling to me that he was really into it, that it was no longer just our trying to figure out if he was exaggerating or not.

He opened his eyes and looked down at me and I said simply, 'You win.'

At that, he started to come, shooting one big squirt straight up, landing back on my hand, lubing up the rest of the job, as he shot a few more times and then dribbled a few more. His shooting was as impressive as his size.

I got up, grabbed the box of tissues, got a few for myself and tossed Michael the box.

'I hate it when I lose,' I told him, and settled back down on the couch as though nothing had happened.
