8 XXX : FreeuseHentai

I really like the idea of the stickers people wear to signal their preferred level of sexual contact, and in particular the male-in-female symbol for full free sex. That's the second hentai work I've seen it in, maybe we could adopt it as a sort of logo or icon representing free use in general.
