Lost a bet

A few months ago I was straight. Didn't really ever see myself with another man, but of course thought about it from time to time.

So how it happened was simple.  I made a bet with a long time friend. If I won I got 500 dollars. If I lost I had to do what he asked.  I took the bet figuring I had the sure thing.  I lost the bet. 

So later that week I'm at my friends house and he asks me if I'm ready to pay up.  I said sure. What do I have to do?  He walked over and said that I had to give him a blowjob.  I screamed "hell no, I'm not doing that".  He laughed and said I was a welcher, that I entered the bet and that agreed to the terms.  I said I didn't care and wasn't going to do it.  We argued about it for about a hour, while having some drinks, when he finally said "you're going to pay up".  At this point he dropped his shorts and stood there in blue boxer briefs. I could see he had a bulge and it was big. I shook my head and said no, but he didn't care. He walked over to me, put his cock about a foot away from me and said "Yes, now pay up welcher".  In a very forceful tone. I shook my head no again but that didn't faze him. He pulled his boxer briefs down and exposed a semi erect cock and that large, and  clean shaven and said "suck it".  I continued to say no.  I looked over saw his cock and then looked up at him and said "I don't want to". He came closer, held the back of my head, put the cock to my lips and said "yes you do, suck IT!!"  I don't know what came over me or why I felt compelled but I opened my mouth and he slid his cock inside.  I nearly gagged at the tip pushed into the back of my throat. I looked up at him and he said "suck it now". I closed my mouth and began to.  His cock got hard as I began to suck. Saliva began filling my mouth as I did and I heard him moan. I tasted what Appeared to be a semi salty fluid. I know now what that was.  He moved his hips as in fucking motion and I just let it happened. I looked up at him while he was doing it and he rubbed his hand thru my hair. After about a minute or so I felt his hand hold my head tighter as he push his cock in deeper and I felt it pulsing  That's when he came in my mouth.  I got nervous and nearly choked and out of instinct began to swallow.  

He pulled his cock out and looked down at me and said "that was good, you'll get better". I left his house and was embarrassed. He called me a few time and we talked about it.  He is such a over bearing guy that I couldn't stop talking to him and because he is that way I went back four times that week and met him twice to give him blowjobs.  Each time swallowing his cum and cleaning his cock with my mouth. The story goes in from here but I will add that later.
