It's just one girl abusing a too dependent girl with no other friends
The fetish picks r unique, but r bad at bringing out said fetishes. Take a look at how they are handled in the top rated stuff on h-sites for those tags. Even the non-h have more effort put into it.
Overall, kinda boring. Bad premise, bad characters, bad yuri relationship, bad effort on fetishism (negating the only good part: unique picks).
