My father's remarriage partner, Rei, came to our house. She suspects that her stepson Makoto, who is not much older than her, is a money hunter. When you sneak a peek into Rei's bedroom, you can see Rei masturbating. Knowing Rei's frustration, Makoto drives Rei into a corner with the aim of her father's absence. She puts on an embarrassing outfit and stirs up her shame, and she gradually trains her into a nasty lustful woman.
