"I can't hold it anymore..." Michiru frantically knocked on the bathroom door, but only her son's voice responded from inside. Seeing he wasn't coming out, she rushed to the garden, unable to wait. Right there, she pulled down her panties and released the urine she could no longer hold. Unaware of being watched by her son, she quietly walked away, leaving the scene as it was. That night, as Michiru slept, her son approached her bedside. Breathing heavily, he gently reached out and began touching her body.
