Group sex with my girlfriend and her lesbian lover

My girlfriend and her hot lesbian lover share a dorm room, and their secret lesbian sex sessions are driving me wild. I can't resist joining in for a threesome.

I had always fantasized about having a threesome with my girlfriend and her lesbian lover. I knew she was into other girls, but I never thought she would actually bring one home. When I walked in on them, I couldn't believe my eyes. My girlfriend was on top of her lover, both of them completely naked. I was instantly turned on by the sight of my girlfriend's pussy being eaten out by another girl. I couldn't help but join in, and soon we were all three of us in bed, fucking and sucking each other. It was the hottest thing I had ever experienced. The sight of my girlfriend's pussy being licked by another girl while I watched was enough to make me cum instantly. I couldn't believe how lucky I was to have such a hot girlfriend who was willing to share her body with another girl.
