Her son was masturbating nonstop again today. As a mother, Hinako felt she had to warn him, so she went into his room. However, what she saw there was her son's secret AV collection. She checked the contents just in case... They were all about married women and mature women. Most of them were incest dramas. She had unexpectedly discovered her son's twisted desires. When she realized that they were directed at her, Hinako felt her body heat up.
