His stepsister is his complacent little bitch.

His stepsister's too horny. She asks you to please teach her how to fuck, because she is tired of kissing with the back of her hand. She gives him a blowjob with a lot of saliva and anxiety, almost desperate. Then she sits on her cock feeling it very deep, and moves sensually handling the rhythm of the fucked. Soon she is jumping on the cock. After that first time, every time they are alone she pounces on the guy to get fucked. Always with that crazy smile
