Bored siblings, Michelle and her brother, find themselves alone and restless. Michelle retreats to the bathroom, her fingers exploring her wet slit, her other hand caressing her full breasts. Her brother, overhearing, bursts in, catching her in the act. They argue, but later, Michelle propositions him, "Let's do this, let's really do this." Naked, they stroke each other, Michelle marveling at her brother's thickness before they're interrupted, leaving them breathless and yearning.
