My wife's bra is askew. (Natsume Yuuki SPRD-674)

The Natsume couple prepared a children's swimming pool because their nephew from the countryside was coming to visit. The spacious courtyard was filled with a cool and open atmosphere, but the husband didn't notice that the beautiful wife, Yuuki's, bra or swimsuit would always slip down, revealing her cute nipples. And the neighbor who noticed this was... well, you know.
