you're going to be poor, and you're going out.

The little, undeveloped girl, Sarachan, was training with her brother every day to become an adult woman. To practice kissing, he stretches his back hard and kisses his older brother, and gently loves him in order to increase the poverty. In addition, a pure sister Sasa-chan asks an adult woman to get used to the sperm of her brother injected by a manko who does not come with hair. Secret training is repeated with your brother until her small wish comes true!
