BTIS-100 - Crossdressing bishonen prostate lesson: Kyo

I suspected it from the cover photo, and the mature co-star was indeed Rin Yuki. She retracted her retirement announcement and is back in the industry—I'm so happy. As a fan, I wish she had more screen time, but since Kyo-chan is the lead, I guess it can't be helped. Still, Rin's moans are incredibly erotic. She really embodies the 'erotic mature woman' vibe. Personally, I like her moans in this one even more than in her last starring role.
