Itsuki is a lonely man who has been single all his life. That's how it should be, and he lived without any effort, thinking that his life was bad and not going well because of the bad world. His only consolation was his niece Moko. If you lose at pachinko and get frustrated, call her and give her a blowjob, and if you get horny, call her to give priority to Moko even though she has something to do and have sex. My niece who is too obedient ... also abuses this affectionate heart and has a distorted uncle's sex life.
