My brothers friend stayed overnight at our house last month when my parents were away. They were both drinking and my brother got sick and went to bed. His friend started messing with me and we were just playing around at first until he started touching my b****** and trying to unbutton my pajamas. He started kissing me and ended up laying on the floor side by side. I knew he had an erection and he began rubbing my v*****. I got aroused right away and I let him undress me and he took his pants and underware off. we didn't have intercouse but for almost an hour we both made out naked and masturbated each other. I never even did that with my boyfriend and he knows who my boyfriend is. Two weeks ago he asked me out on a date. I do like him but I also like my boyfriend a lot and don't want to hurt him. my boyfriend never even saw me naked and I really feel guily about it.
