Alone together with his female friend, the man suddenly suffers from severe stomach pain and locks himself in the bathroom. As he occupies the toilet for an extended period without coming out, the girl waiting outside grows increasingly confused. She too begins to feel the urge to go. Reaching her limit, she has no choice but to relieve herself inside the room. Some use ashtrays, others use trash cans. In the corner of the room, they pull down their panties, bare their buttocks, and defecate into objects that are not toilets. Attempting to hide what they've done, they ultimately have no option but to deal with the mess right there. As the third installment in this fantasy series, the amount of excrement varies—some girls produce only a small amount, while others release extremely large quantities. The defecation scenes are intensely realistic and include implausible scenarios. This work is packed with the unique appeal of the Female Excretion Sect.
