In the confines of their shared bedroom, siblings succumb to the primal pull of lust. The brother, his cock tenting his pajama pants, watches as his sister, clad in a tight tank top and shorts, sleeps fitfully, her body writhing in a dream. Unable to resist, he touches her, his fingers tracing the curve of her breast, the heat of her pussy through her thin shorts. She awakes, her eyes meeting his, her breath hitching as she feels his hardness against her thigh. They hesitate, then surrender, their bodies entwining, their moans filling the room as they fuck, their taboo passion consuming them.
