Went to hook up with a student in Yamagata

Went to hook up with a student in Yamagata. We drove to a large park in Yamagata, where we met the rumored girl, every local men knew her. She looked like a serious, clean-cut student. But that image instantly crashed! How does a pretty face girl with such big tits become so kinky? She was a horny little devil with a great gap!.
