Tristan Summers is being punished by their parents and has to clean her 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. 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 dick. Jay lays down and lets Tristan climb on top of him so she can ride him in cowgirl and then in reverse cowgirl. 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.
