GAR-170 - A reverse Chikan route bus full of school girls and gals!

I know that in 'chikan' (groping) themed videos, not everyone necessarily goes all the way, but why be so faithful to that? The premise is two girls groping a guy on a bus, but it's mostly just oral or handjobs; showing breasts or panties seems to depend entirely on the girls' moods. There's only one actual sex scene out of six, and it's just one-on-one. If this isn't unsatisfying, I don't know what is. Even Dandy productions force them to show their breasts! The cast—RUMIKA, Rio Sakura, Rian, Yukina Mori, and Miu Tsukishima—is solid, but since they barely take anything off, it's a total dud.
