Ricky Spanish pranks his stepsister, Eliza Ibarra, by secretly switching her eyeglasses with an identical pair. Eliza then enters the room and picks up the fake eyeglasses, which she assumes are hers. When she puts on the fake glasses, Eliza finds her vision to be oddly blurry, though she assumes she's just tired from staying up late with her boyfriend. After Eliza leaves the room, Ricky smirks to himself, clearly planning more mischief. A few moments later, Ricky runs into Eliza's boyfriend, Elias Cash, in the hallway. Ricky lies, tricking Elias into leaving the house without saying goodbye to Eliza. Next, Ricky sneaks into Eliza's room and puts on one of Elias' shirts. Eliza then enters and mistakes Ricky for her boyfriend, since her vision is blurred and she thinks Elias hasn't left yet. She kisses him on the cheek, and Ricky is pleased that his plan is working. Sometime later, a naked Ricky spies on the hallway from the bathroom doorway, as if waiting for something. When he finally spots Eliza approaching from down the hall, he jumps into the shower, which is already turned on. Eliza then enters the shower with Ricky, mistaking him once again for Elias. Ricky eagerly fondles Eliza in the shower. Later, Ricky sneaks into Eliza's bed when she's not in the room. Eliza enters and mistakes him again for her boyfriend. She gives him a handjob and blowjob. But when Eliza mounts Ricky, she finally realizes that his dick feels different from her boyfriend's dick... in fact, it feels BIGGER. At first, Eliza is angry at being fooled, but Ricky manages to convince her to keep going!
