[Pixiv / Twitter] [Madeverette] Lu's Bladder Torture (Ongoing)

Collared and trembling, Lu begs his ponytailed mistress for even a drop of relief while a urethral plug keeps his bulging bladder sealed shut. She offers him a devil's bargain—hold everything for ten minutes without leaking and she'll let him pee—but her teasing hands and body keep pushing the sweating tomboy toward the edge, making every second an exquisite agony. Between desperate tears and slow leaks, Lu is about to discover whether he wants to hold on or finally let go.
