I'm your girlfriend's best friend, and my boyfriend and I frequently hang out with you two on double dates. One night the four of us are hanging out and like usual, my bf and your gf get tired and go to bed early-leaving you and me all alone. I confess that your gf told me about your high sex drive and I'm not satisfied in my own relationship, so I want YOU! I start seducing you, telling you I'm going to make you my sex slave. I'm going to use your cock anytime I want, and if you don't comply, I'll tell your gf you were the one coming on to me :)
