I had been living with my roommate for just a short time when I began to fantasize about him. We had met in college, worked together, and slept with many college girls during our party days. He was athletic, built and hung. We had been working out together and came back for a shower. I went first and while I was in there I heard the door handle turn. I mentioned that if he needed to use the toilet he was welcome to even tho I was in there.
Neither one of us was gay even tho I had experimented a couple of times. I had a fascination with the human form whether it was male or female. My roommate and I had been in the same fraternity when a couple of the members came out as gay. We never discussed it but it was on everyone's mind. My roommate and I had pretty good sex lives with our girlfriends but found ourselves wanting at times.
He didn't use the toilet after peeking at me in the shower which I found to be very curious. I continued to wonder what he was up to so I thought I'd play a little to see what he was open to. I got out of the shower and instead of going to my room, I went out to the living room and sat down in my towel. He came over and sat across from me as we talked it up a bit. I had tied my towel in front allowing it open a little revealing my inner thighs a bit more. I began with just moving my legs open and closed a few times and I knew he could see up my leg a bit. He tried a few times to bend over and look up at my crotch. Each time I'd spread my legs a bit more and feeling my cock getting harder each time he tried to 'peek'. At one point I said I need to dressed. Our conversation continued and he followed me into my room. Not sure what to do now that I was tenting out the towel with my now rock hard cock and with it even peeking out a bit if I turned just right. Well, I as I was looking through my closet for something to wear, his eyes were fixed on my raging hard cock as the head poked out about halfway. I dropped the towel as I found something to wear. His eyes wear glued to my hard on and it felt harder than it ever had been. I brushed against it as moved my clothes around to the bed causing it to bounce. I tried to stuff my eager cock into my shorts even though I had grabbed a very loose pair. as the conversation had dropped off altogether and turned into live exhibitionist show with my voyeur just a couple of feet away.
