[ENGLISH-SUBTITLE] JUQ-579 A married woman who received a duplicate key lived alone in a room where a male student was creampied until he graduated. Yuna Shiina

My husband isn't interested in me...Even when we have a drink together, he just tips his glass in a grumpy manner. My husband left first, and I was left alone with Yuzuru, a student who was drinking at the seat next to me. The distance between us becomes shorter and I end up having a relationship with Yuzuru. I received a duplicate key to my room, and I started looking forward to using it to go to Yuzuru's house. And when he comes home, he accepts the sexual desire of the young and active Yuzuru over and over again in a limited time...
