Oliver Flynn and his stepsis Hime Marie get into semantics when Hime gets upset that Oliver was using her computer to look at porn. Oliver points out that Hime looks at porn, too, but Hime calls it erotica and tells him there's a big difference. She proves it by climbing into bed with him and showing him the difference between what he likes and what she likes. Hime points out that Oliver is probably having trouble getting a girl because he watches family porn, which is extra gross. As Hime is trying to show Oliver the difference between his porn and hers, he pulls his dick out and starts stroking it. Hime tries to ignore Oliver's inappropriateness, but he leans in to kiss her on the neck she realizes it's pretty hot to have that attention from her stepdad.
The tension keeps building as they try to make each other see eye to eye. Hime reaches down to touch herself as discretely as possible. Oliver notices and pursues his obvious advantage. Eventually Hime agrees to let Oliver lick her twat, but only over her panties. He asks if he can rub his dick on the outside of Hime's panties, and Hime agrees. After seeing how big Oliver's dick is, Hime agrees to let him slide her underwear aside and fuck her bareback.
Enjoying Oliver's dick on her back is great, but Hime wants it deeper. She rolls onto her belly and takes him from behind. Then she has Oliver lay down so she can hop on that cock and ride him with all the pent-up sexual need. She keeps the motion of her hips hard and steady as she cums, then keeps on moaning as she urges Oliver to cum, too. He does as his hot sis asks, giving her a big juicy creampie.
