Carlos Simoes, a college freshman, recounts his first year away from home, where his fantasies about his sexy step-sister, Fran Simoes, intensify. Every time he sees her curves in their family photos or hears her voice, he can't help but imagine her naked, moaning his name. Finally, one summer break, they're both home alone, and the tension between them is palpable. Fran, with her big tits and round ass, teases him mercilessly, playing with her hair and biting her lip. Carlos, unable to hold back, confesses his desire. They lock eyes, and the room fills with the sound of their heavy breathing as they prepare to make their fantasy a reality.
