JUQ-422 A married woman who received a duplicate key lived alone in a room where a male student was creampied until he graduated. Aina Namiki

One day, Saji, a college student living alone, meets Aina, a housewife, at a nearby pub. Then, the two meet by chance, hit it off, and end up drinking until morning at Zuo Ci's home. Although the relationship between a student and a married woman is not allowed, the relationship between the two deepens. When Saji handed over the duplicate key, Aina started going to Saji's house with a shopping bag in hand when her husband went to work.
