A new, more erotic installment of "Holding in Pee with a Ball" has arrived! In this latest release from Female Excretion Society, the infamous San'untei Bensan returns to explore "erotic, performance-based pissing" like never before. The women are bound, their hands restrained to prevent them from covering their crotches—a unique method that intensifies the experience. Pressing their private areas against a ball forces them to hold in their urine, but as humiliation and arousal blend together, strange wet spots begin to appear on their bodies. These aren't just ordinary urine stains—when touched with a finger while damp, a slippery, viscous fluid oozes out. Being called out on it only deepens their shame and pleasure, making them wetter still. Their faces flush red, eyes glisten with tears, and while turning away in embarrassment, they beg desperately, "Let me go to the bathroom." Ignored and tormented—bladders pressed, genitals teased—their panties become increasingly soaked and stained. Eventually, reaching their limit, the women can no longer hold back and begin leaking urine uncontrollably, fully exposed in the throes of desperate urinary restraint. Featuring seven women whose shame and arousal intertwine, this film marks a bold new challenge from the masters of excretion. *Faces fully shown in the main feature.*
