Ruri is entrusted with taking care of children and answering while a couple of friends are traveling. I found a pink rotor that seems to belong to my friend. Ruri who can not suppress her desire with excitement and immorality that has seen something that should not be seen unintentionally hits her crotch. Then the child who was watching the whole story... The boy, who was lustful for the first time he saw a woman's indecent appearance, did not stop his rampage, and the boy begged Ruri to teach her.
