Bored and isolated, two young siblings, one a virgin, turn to each other for comfort. The sister, a curious teen, starts to masturbate, her fingers finding her wet, untouched pussy. Her brother, unable to resist, joins her, his cock hardening at the sight of her pleasure. Their bodies tense as they bring each other to the brink, their moans echoing in the small room. Just as they're about to cross the line, reality crashes in, their mother's voice calling out, forcing them to quickly compose themselves and hide their shameful secret.
