Taro always feels lonely when he has to live alone. One day, he was returning from work when he came across a woman in the hallway. He could see her nipples through the thin shirt without a bra. Even when she sat down, he could see her most secret place!! That woman was Natsuki, his new neighbor. Her husband always has to go on a business trip for a few months to come home once, so she also feels extremely lonely like him. Stimulated by the beauty of the neighbor, Taro suddenly remembered that the structure of the house next door was the same as this one, so he could look inside her house just by passing through the porch. So he immediately went over to the porch and peeked. But Natsuki also found out, she deliberately masturbated in front of him and used this to threaten him, forcing him to satisfy her sexual desire...
