Myself, your girlfriend & you just got back from the gym. You invite me over for dinner. She goes to take a shower & I start to seduce you. You see my big tits & I promise that I won't tell her. It will be our secret. I start by giving you a hand job. Then a blowjob & before you know it I'm riding you. Talking dirty to you. Trying to stay quiet so she does hear us. You fuck me doggy style. Moaning louder. I ride you again & she catches us. Finally you cum inside my pussy while she watches.
