Maki can't hide her joy when her son, Kazuya, who was a shy and bullied child, brought his childhood friend Junkichi.

Maki cums every time she rubs the back of her vaginal wall that she hasn't touched for a long time. In her reason, she refuses him, but her body gradually cannot suppress the pain in her womb.
