Two curious teens, bored and alone, turn to self-pleasure for solace. One girl, fingers wet with her own excitement, strokes her clit and ass, trying to be quiet. Her brother, oblivious, bursts in, catching her mid-act. They argue, but later, they decide to explore their desires together. Naked, they watch each other masturbate, the girl's fingers glistening as she imagines his thick cock inside her. Just as they're about to act, they're interrupted, leaving them breathless and yearning.
