Caught in the throes of puberty and boredom, a curious teen sister retreats to the bathroom, her fingers tracing circles on her tender clit, hips bucking as she imagines her brother's touch. Unbeknownst to her, he's watching, his cock hardening at the sight of her wet, pink pussy. They clash, she curses, but later, they reunite, naked and lustful, his thick cock bobbing as she strokes it. Just as they're about to seal their taboo union, a voice echoes, ending their heated moment.
