In the stifling heat of the afternoon, step-siblings Michelle and Jake find solace in self-pleasure. Michelle's fingers dance on her clit, her moans echoing in the empty house. Jake, overhearing, catches her mid-act, sending her scrambling for cover. Anger erupts, but so does curiosity. Later, they reunite, naked and aroused, Jake's thick cock tenting his boxers. Michelle's eyes widen, hungry for what she's never had. Just as they're about to cross the line, a creaking floorboard freezes them, leaving them breathless and yearning.
