Boredom turns to lust as step-siblings Michelle and her brother find themselves alone, their mutual annoyance morphing into a heated argument. Caught masturbating in the bathroom, Michelle's anger boils over, but later, desire trumps resentment. Naked, they explore each other's bodies, Michelle's fingers tracing her brother's thick, straight cock as he jerks off. She fantasizes about feeling him inside her, and just as they're about to give in, a sudden noise forces them apart, leaving them breathless and aching for the forbidden fruits they've barely tasted.
