Middle-aged Aritomo led a double life – a bank manager by day, and a human toilet by night. Tonight’s client, Aya, relished in fastening his jaw with a broken bottle, as she prepared to relieve herself. With her sweaty nether regions exposed, Aritomo could only swallow his pride and endure the stench of her urine. The taste was a peculiar mix of salty, bitter, and sour. But Aritomo did not dare to let any of it go to waste, lest he incurs his mistress’ wrath. Aya emptied her bladder, filling Aritomo’s mouth with a good quart of her urine. Aritomo then opened his mouth wide, allowing Aya to sit on his face and grind her unwashed pussy and pee hole onto his mouth and nose. The smell was overpowering, but Aritomo had no choice but to endure, as he embraced his role as a human toilet slave.
