A high school girl who feels a little cute everywhere. It all started when the child's mother remarried and had a new father-in-law. At first, I didn't have that kind of atmosphere at all, but I'm sure anyone would feel the same way if I saw a daughter of a bloodless age wandering around in a miniskirt every day. A father-in-law who is gradually looking at his daughter with a disgusting look. One day, when my father-in-law came home from drinking, he saw my daughter's unprotected panties sleeping in the living room and finally put out his hand. A father-in-law who touches the crotch from the top of the panties so as not to be noticed. Mother is sleeping in the bedroom. The play escalates, and naturally my daughter wakes up, leading to a ridiculous development...! ?
