Two siblings, alone and restless, find solace in self-pleasure. The girl's fingers dance on her wet clit, her other hand squeezing her full breast. Her brother, hidden but watching, strokes his hard cock, imagining his sister's touch. Caught in the act, they argue, but desire trumps anger. Naked, they face each other, the girl's eyes widening at her brother's size. She fantasizes about his cock filling her, but a sudden noise breaks the spell, leaving them breathless and aching.
