Originally intended to be a pissing video, this unique release captures the bizarre and unexpected twist of sudden bowel movements. Featuring scenes of extreme pissing, self-recorded pissing endurance, and accidents during lap-trap sessions, it continuously shocks viewers with one surprise after another. All participants except the fourth girl have loose stools, making it inevitable for poop to come out alongside urine. However, the fourth girl experiences an unbelievable incident—after finishing urination, she suddenly feels the urge to defecate. Due to her traditional Japanese-style sitting posture and the consistency of her stool, she unintentionally lets out feces. Undigested food particles are visible in the mess, and her expressions overflow with embarrassment and regret. Pushed beyond her limits, she stands frozen, helplessly stomping her feet. Eventually, she loses control and soils herself—the brown stain spreading vividly across her underwear. She briefly notices something strange in the toilet bowl, but the satisfaction of just having pooped distracts her. Yellowish-brown sludge takes over the surface of the plastic wrap, spreading wider and wider. The excitement builds as she continues enduring with her heel pressed against her anus. She even predicts, "I can feel the poop just a few millimeters outside my ass," conveying intense real-time sensations. Despite finishing urination, the urge persists, and she ends up expelling a monstrous pile of shit. Includes episodes from the Excretion Society. The main video also includes facial exposure.
