Siblings locked in a playful battle, the sister challenges her brother to a game of dares. She loses and, as punishment, must pleasure his throbbing cock. She hesitates, but curiosity and lust win out. She takes his thick, veiny dick into her small hand, stroking it gently. He grows hard, and she tentatively licks the tip, tasting his precum. She takes him deep into her mouth, gagging slightly, before he pulls out and shoots his load all over her face in a hot, satisfying cumshot.
