Is she the ultimate brother-loving girl, Ryoka? A sister who visits her brother's house every weekend. Unaware of his sister's feelings, the brother secretly uploads footage of her being trapped to a certain site. The site goes wild over the hidden affairs of an ultra-cute girl, with everyone wanting to meet her. Exploiting his pure-hearted sister's feelings, he takes Ryoka to various places where her fans await, and she can't refuse, gradually being trained into a highly sensitive girl who accepts live on-stage ejaculation.
