R34 has been slacking. I've been waiting for people to start fetishizing surgical masks.
I mean, it isn't "that" strange, there is a niche of people who like gas masks...
Is there a fetish for people in gas maska, though? I can only think of one manga (good vibrations, which I recommend if you want the hentai equivalent of Eraserhead).
edit: don't forget to close out your spoiler tags, otherwise bad things happen to replies.
