In the dim light of their shared room, the sister can't resist the temptation of her brother's pseudo dick. She straddles him, her breath hitching as she sinks down, feeling every inch of him stretch her tight pussy. She rides him slowly, building a rhythm, her tits bouncing in his face. He grabs them, squeezing hard as he thrusts up, meeting her stroke for stroke. Their bodies are slick with sweat, the sound of their fucking filling the room as they race towards their climax.
