Sugar Daddy
Taehyung sells his body for money. A slut for older cock.
Until Jeon Jeongguk takes him in as a sugar baby. Nothing changes much, he is still stuffed all day with cock. He is still a free use, cock hungry slut. But now Jeongguk likes to stuff him full of his cock 24/7.
Or, another free use Taehyung universe.
