Kanojo no Imouto to Himitsu no Stay Home -Uchiki Musume ga Haitoku Netori | 彼女の妹と秘密のステイホーム～内気娘が背徳寝取り！～

Tenshu Sayoko. My girlfriend from school days. I love her so much that after I got a job, I immediately started thinking about marriage and a little while ago, we started living together to prepare for marriage, as approved by both families. She has a younger sister ..., Emiru Amafune who is serious but not very good at socializing and is a bit off.

Their parents house is to be renovated due to its age. During the renovation, her parents moved to a monthly rental house near their work. However, Emiru is also a student and if she follows her parents, her school will be too far away, So Emi moved in with me for a limited period of time, because it was convenient for her to go to school. At first Emiru didn't greet me well and of course she didn't talk to me. But over time, she gradually became more friendly and less sullen, although she didn't smile.

Then one day, while I was working and studying with Emiru, ...... Emiru started shuffling around and touching me. It's not a coincidence, but it's a feigned coincidence and it's a light touch. She was very close to me, deliberately bumping her hands and intertwining her legs. And she would stare at me awkwardly but seductively...
