VEC-377 My boyfriend was stolen by my mother, who has an insatiable sex drive and a habit of cheating. Kawakami Yuu.

It's been a year since we started dating. Shinya, who was invited to her house for the first time, arrived earlier than expected due to nervousness. When I timidly press the intercom, it was her mother, Yu, who greeted me instead of her. The two of them ended up waiting together for her, who had just gone shopping. Shinya can't help but worry about Yu, who seems to have an adult sex appeal. Yu, who noticed Shinya's gaze, seduced her with her impetuosity.
