VENU-340 Silent play: My dad's next to me… Shiho

I've been married for five years, and my husband is a kind man who always cares about me. But I have a secret that I can never tell him. I've fallen in love with his stepchild, Ryo. And I've crossed a line that should never be crossed. Recently, I've become excited by the idea of doing lewd things with Ryo without my husband finding out. The tension of knowing whether I'll be found out or not makes me even more lewd.
