Your sexy step-sister shyly asks you a personal question: do the girls you have sex with let you fuck them in their buttholes? You tell her that yes, every girl you've ever had sex with has done anal with you. Your step-sister, surprised by your answer, explains that her boyfriend has threatened to break up with her if she doesn't take it up the ass. She doesn't want to lose him, but she's afraid to get fucked in her tight, virgin butthole. You ask if she'd like some help training her ass, since the women you buttfuck tell you that you're very good at it. She's nervous, but she trusts her step-brother, so she lets you go for it. You have her lay on her back while you slowly penetrate her. To your step-sister's surprise, she loves the way it feels! She quickly gets into it, rubbing her clit and begging for more. After a few minutes, you have her flip over into doggy so you can drill her ass from behind. Step-Sister loves feeling like a dirty anal whore! She starts to talk nasty about how much she likes it in her poopchute. You even convince your naive step-sister to lick your dirty dick directly after it's been in her back door. Believe it or not, your slutty step-sister loves the taste! She finishes you off by riding you with her ass in reverse cowgirl. To her shock, she even manages to have an anal orgasm while you give her slutty butt a massive creampie!
