This felt like a horror game to me, despite the fetish aspect. The coziest horror I've ever read.
The understated traumas, the soft but melancholy music, and the eerily pastel illustrations all contributed to the feel of the point-of-view characters' gradual loss of will and their eventual surrender to obedience.
If, instead of the common thread being a sadistically cruel lesbian, it was narrated by a deadpan man smoking a cigarette, it would feel like a Twilight Zone episode.
