JUL-131 For the past two months, I've been serving as a practice dummy for child-rearing for the married woman who moved in next door—. Sachiko

Sachiko, who has moved in next door to Shuhei, who lives alone, wants children, but has always been shy. Recently, her husband has been uncooperative in her child-making, and her anxiety about child-rearing is increasing. One day, Shuhei tells Sachiko about her troubles and suggests that she practice raising her child. Sachiko treats Shuhei seriously like a child, but there is no way she can control Shuhei's rationality because of the huge breasts that spread out in front of her... After that, a secret meeting called childcare practice between a married woman and a young man began.
