Distracted Step Sister from Studying to Fuck Her Tight Pussy

Parents are away, and my step brother gets so bored that he distracts me from the coursework I must finish today. I try to push him away from me, but he insensibly takes out his cock and puts it in my hand! I agree to give him pleasure if he won't distract me anymore. I give him a sloppy blowjob, after which he fucks me and I ride his cock. In the end, he cums deeply in my mouth and I swallow all his cum.
