Visiting my mother at night

Yukari, who is raising her only son Yudai by herself while working as a housekeeper, can't hide her tiredness from her difficult life. She goes home and sleeps like dirt, and has no way of knowing that Yudai has special feelings for her... One evening, Yudai sneaks into Yukari's bedroom and touches his mother's overwhelming body, and is unable to control himself and finally crosses the line. My mother's defenseless sleeping face... my mother's calm sleeping breath... turned into something lewd...
