Kayoinbo ~Waga Ko no Geshuku de Onna ni Modoru Haha~

The protagonist, Kanbara Tooru, has just started living alone in the spring. His mother, Chihiro, calls him almost daily with nagging questions, which he finds annoying. Despite this, he often relies on his friend's mother and the owner of the apartment, Inami Akiho, who is of a similar age to his mother but has a more attractive physique. Tooru is surrounded by attractive adult women, such as his aunt Aiba Mutsumi and former teacher Sogawa Atsuko. When his mother Chihiro comes to visit him, he starts to appreciate her love and care, as well as realizing that she is as glamorous as Akiho, which leads him to ask her for a sexual encounter.
