With a flick of her tongue, the rebellious sister tastes her brother's cock for the first time, her eyes locked with his in the dim closet light. As she takes him deeper, she feels his hands grip her hair, guiding her rhythm. Her brother, now rock-hard, pushes her against the wall, his fingers finding her wet, throbbing pussy. Their bodies move in sync, a dance of lust and taboo, as they chase their orgasms, ignoring the world outside their secret haven.
