ROYD-361 I was initiated by my voluptuous older stepsister… and then chased all around the house in a frenzied, high-speed encounter! Repeatedly and intensely until I could no longer get aroused. Sunao Kuui

I’m the only one in my class who’s still inexperienced… When I’m feeling down, my older stepsister offers to listen and help me out. And then she even suggests, If you want, why don’t we try being intimate? Taking her up on the offer, I finally have my first experience. But I’m still not satisfied. It feels so good that I want another round. Still not enough. Just when I’m thinking about going again, my stepsister runs away. I chase her all around the house and keep pursuing her until I’m satisfied. It won’t end until I’m fully content!
