Yurika is a good woman but she's a frank and generous mother. She is elderly, has a significant age gap with her husband who is always on business trips, and they have been in a sexless state for years! During the summer vacation, her son, who had retired from club activities, started to notice his mother's body and appearance more and more each day, eventually hiding and masturbating with his mother's panties! His mother also noticed her son's erection and started to take an interest... One night, the son could no longer hold back and brought his mother into his room, pushing her onto the bed! His mother's body also involuntarily became excited by the long-forgotten sensation! The compatibility of their bodies after crossing that forbidden line was surprisingly excellent!? Although it was supposed to be just once, of course, they couldn't stop there and kept going at it! Overwhelmed by their insatiable lust, they ended up having sex everywhere in the house, multiple times, with him ejaculating inside her each time.
