In a cramped, dimly lit apartment, Michelle and her stepbrother, both strapped for cash, decide to explore the taboo to make rent. She offers her tight, untouched body, while he barters his massive cock. They awkwardly negotiate terms, her hands trembling as she touches his hardness for the first time. He, equally nervous, watches her undress, revealing her perky tits and smooth, virgin pussy. They clumsily start, him licking her slit while she strokes his stiff dick, but soon find a rhythm, their bodies responding to each other's touch. They fuck missionary, then cowgirl, her tight cunt gripping his cock as they chase their first forbidden orgasm.
