Hidden beneath the sheets, the siblings succumb to their forbidden cravings. The brother's hands explore his sister's body, tracing the curve of her hip, the swell of her breast. She shivers, her nipples hardening, as he slips a finger inside her wet heat. She returns the favor, wrapping her hand around his stiff cock, stroking him until he's panting. They come together, her riding him, their bodies moving in sync, their eyes locked. The room fills with the scent of sex and the sound of their ragged breaths, their moans of pleasure echoing in the night.
