My friend's boyfriend is a very handsome and funny man. I never had any active sexual thoughts about him because I know he's in a relationship with my best friend and I didn't want to be a bitch to her, even if she was to me, in the past, by fucking my very first boyfriend! But let's get over that... I came because I borrowed some books from her, like a month ago and she didn't to give them back to me, and instead asked me to come and take them. She obviously cares a lot about me and my books... she isn't even home, and she knew I was gonna be there. I found her nice boyfriend instead and we got to talking. I told him some things about my friendship with his girlfriend, including that she fucked my BF but that was a long time ago and I don't care so much about it now. Of course one thing led to another we were already discussing about sex! The atmosphere became more tense, I could feel the sexual tension between us. I told him I I like to fuck around and can't commit to a single guy and bragged about my wonderful blowjobs :D He said his girlfriend is very prudish and it's impossible to have such discussions with her. I noticed his forming boner and was glad to help, in two seconds I was kneeling in front of him with my mouth around his cock. We had a lot of fun, especially by mocking his gf'ds personality and tiny A cup tits... I Sucked him, DeepThroated him and rubbed his hard cock while occasionally throwing snide remarks about our common friend. And to push the point home I grabbed that throbbing cock and put it between My Big Boobies for a Hard TitJob - something his pathetic girlfriend could never do with her tiny tits! I Used my Boobs to make him cum, completely Hands-Free, he exploded all over my chest and Boobies, cum dripping in between them! And that was my cheating story, ladies and gentlemen.
