Tristan Summers is being punished by their parents and has to clean her stepbrother, Jay's, room. Tristan is pretty grossed out by what she finds. Jay starts making comments about how Tristan's tits have grown. He pops his dick out to start stroking it off, and in retaliation Tristan flashes him her boobs. When Jay keeps it up, Tristan peels off her skirt and lays down on Jay's bed to masturbate. Their stand off escalates when Tristan mocks Jay about his stamina. Eventually, he lets her reach out to stroke his hardon. Tristan takes the opportunity to stick it in.

With her breathy moans, Tristan has soon enticed Jay to really give it to her. She draws her knees back to open herself up completely to Jay's stiffie. Reaching down, she spreads her folds in a blatant invitation and to make it easy for her to rub her own clitoris. This horny little piece isn't satisfied with just one climax, so she rolls onto her belly and wiggles her ass to entice Jay back inside.

Jay is happy to take Tristan in doggy. Her slim body fits easily into Jay's hands, especially as he palms her ass while fucking her. When Tristan rolls over and shoves her breasts together, Jay eagerly takes her up on the offer of a titty fuck and then a BJ that lets Tristan suck her own juices off big brother's dick. Jay lays down and lets Tristan climb on top of him so she can ride him in cowgirl and then in reverse cowgirl. On her back once again, Tristan lets Jay keep pounding away until he's on the verge of cumming. He pulls out at the last second to pop all over his stepsister's belly in a shower of love.
