In the dim light of the closet, the siblings' breathing grows heavy, their bodies pressing against each other as they try to maintain their virtue. But the air is thick with lust, and soon, the brother's cock is free, standing stiff and proud. His sister, unable to resist, takes it in her hand, stroking it gently before guiding it to her eager, untouched pussy. She rides him slowly, her tight cunt gripping his cock as they both fight the guilt that threatens to consume them. As they reach their peak, the brother pulls out, his cock glistening with their mixed juices. He pushes it into his sister's mouth, and she sucks him clean, swallowing every last drop of their forbidden pleasure.
