With her skirt pulled up and her legs spread wide in a fixed position, she faces the extremely intense challenge of holding in her urine. A dial lock is attached to her hand, rigged so that if she lets go, she'll immediately wet herself—making the endurance limit exceptionally harsh. The standing spread-leg posture is extremely difficult for a girl, causing sweat to drench her body and pour down like a waterfall. Her lower half, with pantyhose and underwear fully exposed, becomes a target for intense humiliation. Some girls drip urine drop by drop, while others lose control completely and release everything in one sudden burst. This production lets you fully enjoy erotic hip-swinging endurance, packed with humiliation and pissing. Five girls take on the challenge in their own unique ways. Haruka, the cool older sister, shows no signs of panic and seems capable of lasting a long time—but ultimately is forced to pee herself. Yuuko tries to endure by swaying her hips side to side, but a brief lapse in focus leads to an unexpected accident. Umi already has an urgent need before the challenge even begins; she can't even listen to the instructions and fails to touch the lock, wetting herself almost immediately. Mei's bladder is completely full, pushing her limits until, in the end, she gushes a torrent from her crotch. Watching how each girl reacts under pressure, enduring both physical strain and deep shame, is the main attraction. The main feature includes clear facial shots—enjoy the raw, realistic reactions.
