Della Cate is pissed that she has to share a room with her new stepbrother, Jay Romero. Jay's not thrilled about it either, but he puts Della's things into the room. Later, Della is getting ready for bed when Jay walks in on her. They bicker about the room's rules, and eventually get under the covers together.

The argument continues as Della tells Jay to stop touching her. He swears he's not doing it on purpose, and Della quickly figures out that it's Jay's hardon. She likes that, so she begins to bump and grind against him. That opens the flood gates for some titty groping and then Della giving in to her baser urges to blow her stepbrother's cock.

Now that she's seen for herself what a nice dick Jay has, Della wants it inside her. She crawls on top of his hips and tugs her thong to the side to fill herself to the brim with the D. Getting on her knees, Della peels her underwear off so Jay can do her in doggy with no obstacles. Jay finishes his stepsister off as she lays on her back so he can bury himself between her thighs. Pulling out, Jay lets Della stroke him off all over her. They agree they can keep this up as long as Della's mom doesn't find out.
