The neighbor came over to take a shower but forgot to close the door and that was the end

Miura Sakura often goes to her neighbor's house to ask for a bath because her house is having problems. The guy and his wife were still very normal, allowing her to bathe not only one day but also many days after that. Every day she came over to visit, the homeowner became curious and peeped at her bathing. Then whatever happens will happen.
