During an adult role-play scenario, Hikari Aozora returns to the countryside after a long absence and reunites with an older neighbor. She thinks he is simply a kind man who looks after her, but he is actually an obsessive pervert who has stalked her since childhood. He seizes every opportunity to rape her day after day. Being covered in his sweat and drool should disgust her, yet her body gradually awakens to a throbbing, unwanted pleasure.
