Mio Kimijima drops her underwear at her difficult neighbor's house: Mio Kimijima is a married woman, her sister's life is still going on until her perverted neighbor often masturbates alone in the other room, discovering Mio Kimijima's underwear from the upper floor of the bat down to her house. He started to complain and then what would happen to Mio Kimijima, inviting the gay brothers to watch it together!!
