Matt Bird and his stepsister Aria Logan don't get along very well, but Matt's willing to be nice to his stepsis if she'll do his homework for him. He and Aria spar via text message, with Aria insulting Matt's manhood and Matt claiming he can make his sis cum in a couple of minutes. Matt really doesn't want to do his schoolwork, so he pulls down his pants to prove that his dick is big enough for her pleasure and then pulls her close to feast on her bald fuck hole even though their parents, Tommie and Mary Kalisy, are right there in the room with them.

Entranced by Matt's hardon, Aria sinks to her knees and pulls her brother's fuck stick nice and close so she can lick it up and down then suck it like a lollipop. He rewards her oral efforts by bending her over the table and slamming into her from behind. Their doggy style fuck gets even more wild when Matt pulls Aria into his arms and bounces her up and down on his dick while squeezing her tits in time to his strokes.

The stepsiblings have some trouble holding the moan as they keep banging, but they do their best. When Aria slides into Matt's lap to give him a stiffie ride in her greedy twat, his big hands on her ass and his big dick inside her combine to really get her motor running. He finishes her off on the table, taking her hard and deep until her pussy pulses with delight. Pulling out, Matt covers Aria's belly and mound with a big shot of cum. They're just basking in the afterglow when their mom calls them to dinner.
