This work, created by the infamous Sanmitsutei Bensan, portrays an annual erotic and playful depiction of pissing accidents. This time, the women—desperate to hold in their urine—are bound with their hands tied, their attempts to block themselves completely sealed off. They are forced to press their crotches tightly against a ball, enduring intense pressure as they struggle to hold back. As they grind their privates harder against the ball, humiliation and erotic excitement blend into one, causing new wet spots to bloom on their panties. These stains are not mere traces of urine, but unique manifestations of their shame and arousal. When touched, a slippery, sticky fluid oozes out, and being called out only pushes their humiliation and desperation further, until their panties are soaked through and their limits are finally broken, releasing a full stream of urine. The scene captures the intensely erotic tension of being watched while trying to hold it in, weaving shame and arousal into a deeply stimulating spectacle. This production masterfully captures the moment of release through its unique approach. (Haietsuya) ※ Faces visible in main feature
