At first glance, they seem like an ordinary mother and son who get along well. But the bond between Kanako and Kazuya, who grew up huddled together in a single-parent household, is so strong and strong. He can tell his mother anything and depend on her. For Kazuya, who thinks this way, and is still a virgin with no girlfriend, it was only natural that he would ask his mother to take his virginity. Kanako tries to counsel her son as a mother. But Kanako herself is also hungry for cock... It's a world of just the two of them, isolated from society. No one can blame them.
