[VAGU-234] Literary mothers restrain their son's friends so that they can't resist and let them pies out.

Eriko has a past in which her hobby of appreciation of literature has been aimed at being as a researcher in the National Faculty of Letters. She is now married and taking care of her only son as a full-time housewife. After marriage, Erika found time and was working on literature appreciation, but while reading the works of the Atsumi school, she became greedy. Now that her husband was away from home, there was no husband and wife's life, and Erika's body was completely frustrated. At that time, I felt sexual excitement in the manly body of my son's friend who came to play.
