"If this keeps up, I'll pee..."Michiru hurriedly knocked on the bathroom door. However, the voice of her son came from the bathroom, and it seemed that there was no sign of him coming out. She had reached her limit. Michiru went out to the garden desperately trying not to stimulate her stomach even a little, and quickly took off her panties and relieved herself there and then. She was unaware that her son was watching her... That night, her son came to her while she was Michiru, and began to grope her body with heavy Michiru.
