I'm Yoshinobu. I live with my father who remarried and a woman who is called a stepmother. It seems that my stepmother has recently started to worry about her figure, and she has started to wear a sample of a corset (corset) that she received as a gift from her mother friends when they came to visit. However, I feel embarrassed to look at my stepmother, who shows me the line of her body by saying, "How do you like this corset, Yoshi-kun?"
