Undercover report series from the excretion delivery health service "Haietsudo": "The Urge to Defecate!" This time, we've requested the minimalistic heavy-urinator girl, Tuyu. She has a unique charm and atmosphere unlike any girl we've seen before. Even during conversation, she appears restless, clearly with a completely full bladder. Taking her condition into account, we begin stimulating her with a vibrator and cunnilingus. Tuyu writhes in agony from the dual assault of urinary urgency and erotic touch. Eventually, she can no longer endure it and releases her pent-up urine. A steady stream pours into a large measuring cup, totaling nearly 1100cc—an impressive scene showcasing the true skill of Excretion House. (Facial visible in main feature.)
