【Chinese pattern】I slept with my sister and made her even more mine.

I’m a working adult living on my own, and my sister came to my house.
My hometown is too rural, so I went to school in the one I’m in.
But my sister has a very sexy body, and even though she’s supposed to be my sister, I’m conscious of her.

And finally, I couldn’t take it anymore, so I put my hands on my sleeping sister…

But for some reason, we ended up going out as lovers after that.

It’s about a brother and sister sleeping together.
