This role-play is performed by adults. Saki is 36 years old, remarried to her husband who was older than her, and had a new son. My son, Yuuki, is a bit of a mother's boy, probably because he has been in a fatherless household for a long time. He brings her with him on his way home from school. Saki goes to the front of the room with a cup of tea and peeks through the gap and witnesses him failing to have sex for the first time. Afterwards, Saki consoles her depressed son... ``Never tell your father.'' A mother gently teaches her son how to practice sex. Mom Saki's maternal love is stronger than blood ties! !
