He's sleeping with his girlfriend and the stepsister wakes him up telling him to be quiet. She gives him a blowjob making his cock very hard. Then she puts her cock in her pussy fucking herself by opening her ass cheeks with her hands. She fucks the stepbrother in different positions, even wanking the cock with her tits. He fucks her again while he puts a finger in her ass and then she sucks his cock and masturbates him until he ejaculates and the girl gathers the semen from the boy's body with her mouth swallowing all the semen.
