【Celica】What, my sister is a man? ～A misunderstanding H in the futon 3

I’m hot and numb.
I’d like to know what you think of this.

–One day, my parents remarried and I had a younger sister (a cute angel with big tits).

But her sister is a little strange! She actively invites me, a man, to take a bath and sleep with her!

There’s a reason for this…my sister thinks I’m her big sister…!

–The softness of her boobs in close contact with me made my rational mind collapse!

When I play with my sleeping sister, her pussy gets all wet and she starts to shake and jiggle!

I can’t stand it, and when I insert myself into her, she finally finds out that I’m a [man]!
