The closet, their sanctuary, fills with the scent of their lust. The brother, his cock aching, pushes his sister onto her knees. She eagerly takes him in, her mouth stretching to accommodate his size. He grips her hair, guiding her, as she bobs, her saliva coating his shaft. Meanwhile, her hand works her clit, her moans vibrating around his cock. Their pace quickens, bodies tensing, as they race towards climax. The brother pulls out, his hot seed spilling onto his sister's waiting tongue, while she fingers herself to her own shuddering orgasm.
