A few years ago during football season a buddy and I that liked different teams were playing each other one weekend and we were going to make a bet on the game. We bickered about what the bet would be, Loser buys 3 cases of beer, buys pizza for a week, Streak through the neighborhood or give the other a blowjob. To my knowledge my friend was not gay and I never really thought about sex with another man. Anyways we couldn't decide to we wrote the bets down on separate pieces of paper and put them in the bowl and mixed them up. Which ever one was picked out that would be the bet. We had his sister pick it out but she didn't know what the bet was as she was in a hurry so she grabbed it and handed it to us and left.
Well she picked out the blowjob one so the bet was set that the loser had to give the winner a blowjob to completion. Well that weekend came and my team lost. Now his sister is over at his place a lot and pretty much comes and goes at will, he had remodeled his basement into a man cave which was awesome with a 106 inch big screen, pool table, bumper pool and a couple pinball machines. Anyways reluctantly we made arrangements to pay up the bet and I was not really looking forward to paying up. So the day came and we were in the cave and I finally got up the nerve to pay up and got on my knees and he dropped his pants and started stroking his cock. After a couple minutes and building up the nerve I put his cock in my mouth and started sucking. It felt like forever but probably 15 to 20 minutes he finally is ready to cum and just as he was in walks his sister and because she startled us I pull off his cock just as he shoots a stream of cum into my face as I went to look at her.
She spun around and headed upstairs. It kind of ruined the moment and I know she seen the cum on my face as well as me holding his 7 inch hard on in my hand and on my knees. I say I am bi only because I didn't mind sucking his cock once I got use to it and would suck cock again.
