SDMU-068 In a mixed-bath hot spring where perverted old men are lying in wait, a clueless local high school girl reports on the hot spring wearing only a bath towel! If surrounded by strangers' erect penises, will she end up accepting her first humiliatin

In Yamanashi Prefecture, there is a "mixed bath hot spring where exhibitionists gather." We had local high school girls enter the bath under the pretense of a "hot spring report program"! Unaware high school girls in just towels are surrounded by male customers (exhibitionists) with erect penises. Will these high school girls, surrounded by the perverted erections of men, end up having sex out of embarrassed arousal from adult techniques that their male classmates couldn't provide?!
