This explains a photo series I recently saw of Stoya... Anyway, I always find fetishes that are counter-intuitive to sexual intercourse fascinating. I worked at a sex shop through law school and I quickly discovered EVERYTHING can be a fetish. I like the idea of a lesser known fetish being placed out in public like this.
The stillness and motion create a tense contrast reflected by the stark red against the background of muted colors. I think the only way this could be better is if that yellow mat were less vividly colored. Then, it would be motion vs stillness and vivid vs drab.
