Katie Kush has a school project to make sure she can take care of a real live baby. She's not doing a great job of it when her stepbrother, David Lee, walks in and catches her trying to breastfeed the doll. He takes it from her and demonstrates how to make the doll stop crying. As he shows Katie how to take care of the pretend baby, Katie is incredibly turned on. She realizes she wants a baby with David. She tells him as such, but he's not about to get his stepsis knocked up. That just gets Katie more determined than ever to get her stepbrother's cum.Katie waits until David is sleeping before creeping into his bed the next morning. She rubs her thong-clad ass against his morning wood and then puts his hand don her tits. David wakes up to Katie talking dirty and writhing against him. She guides his hand down to see how wet her pussy is. David may be weirded out, but once his fingers are slipping up and down Katie's slit, he's sold. He agrees to slip it in so they can spoon together while he fucks her.David is committed now, and Katie is ready to take full advantage. She sucks their combined juices from his cock as she rolls him onto his back so she can mount him in reverse cowgirl. Katie's trimmed twat is so wet it just glides right down on that hard cock. She wants it in doggy next, and David gives it to her. After another BJ, this time with some hot deep throat action, Katie gets on her back and invites her stepbrother back inside one last time. She waits until David is about to pull out to bust his nut before she wraps her legs around him to keep him buried inside so he can hopefully get her pregnant.
