Bunny Colby is busting out of her clothes, but she is still enchanted with grown up versions of the games she played when she was little. Lately, she's been wanting to play with her stepbrother, Nathan Bronson. Nathan is uncomfortable with the way his stepsis sexualizes everything, but he also wants to make her happy. Today, Bunny wants to play house where they act as though they are oversized versions of childhood dolls. Bunny wants to pretend they've gotten married and they have a dream house. Nathan is not willing to play that game, so he tells Bunny to think of something else and then leaves for his bedroom.

Nathan's disappearance gives Bunny the chance she needs to prepare for her playdate. She creates a doll box for Nathan to open and puts on a bathing suit before climbing inside. When Nathan returns, Bunny only responds the way she imagines her favorite doll might. She wants Nathan to unbox her and play house! Eventually, Bunny coaxes Nathan into opening the box. Once she is free, Bunny insists that she wants to keep playing with Nathan so she can take care of him like a good pretend wife. Nathan finally agrees as long as Bunny promises her mom won't ever find out. With Nathan's permission, Bunny drops to a crouch and tugs his shorts down to spring his dick free. Her hands wrap around the root of Nathan's hardon to draw him into her mouth, where she sucks him down like her favorite lollipop. Even though Nathan remains a little bit hesitant, he doesn't want to stop when Bunny checks with him. Instead, they relocate to the couch so that Bunny can keep on sucking him down and even pop those massive boobies out for a titty fuck.

With his stepsister on top of him using her hand and mouth and jugs to get him nice and hard, Nathan doesn't stand a chance at doing anything but seeing this through. When Bunny tugs the bottom of her bathing suit aside and sinks down onto Nathan's cock, he's super into it. Bunny's stiffie ride makes her jugs jiggle in such a delightful show. When she turns around for some reverse cowgirl action, Bunny makes sure to rub her clit until her moans of delight fill the room. Since Bunny wants to be a good little pretend wifey, Nathan gets her on her hands and knees next so he can dive deep and hard into her tight cooch. Bunny is happy to play, eagerly backing up to meet each of Nathan's strokes. She winds up on her back with her stepbrother's dick back between her thighs as he brings her off one last time. Pulling out as he feels himself getting ready to cum, Nathan takes Bunny up on her offer of another titty fuck to bring himself home. Even as Bunny is licking herself clean of her stepbro's jizz, she offers to hide the doll box in the garage so they can play again tomorrow.
