My boyfriend's friend caught me grinding and making out with a guy at a bar one night when I was drunk. He blackmailed me and threatened to tell my boyfriend what he saw unless I did something for him. He said that if I came over to his dorm and sucked his dick whenever he wanted for the rest of the semester he would not tell. I thought this was ridiculous but knew if my boyfriend found out he would break up with me. I decided to give in and took the deal. I usually gave him head 2-3 times a week. We never kissed and he never got to see me undressed. I went over usually without saying a word, pulled down his pants, would suck his dick for 5-10 minutes, swallow and then leave. I would act disgusted, but truthfully I actually got turned on when I gave him blowjobs. He kept his word and never told.
