On a weekend hot-spring trip, an adult woman around twenty travels with her male partner in his fifties. He loves training her, and she eagerly shares every one of his extreme kinks. This naturally submissive exhibitionist adores bondage, anal violation, and public humiliation. Inside the inn and at the open-air baths, both her twitching pussy and anus are fingered and stretched until cocks plug every hole, making her cum hard again and again.
