In the dim light of their shared room, the siblings can't deny their mutual attraction any longer. The brother, a strapping young man, watches his sister undress, her body ripe and ready. She catches him looking and smiles, a wicked glint in her eye. She beckons him, and he can't resist. He joins her on the bed, his hands exploring her curves, her own hands eager to free his throbbing cock. She takes him into her mouth, her lips stretching to accommodate his size. He groans, then flips her onto her back, spreading her legs wide. He plunges into her, their bodies slapping together, their pleasure echoing through the room. They come together, their bodies shaking with the intensity of their release.
