I’m currently in Japan, and a friend of mine, who is fond of yaoi, asked me to bring her back a (I quote) “hentai vanilla yaoi oneshot, so that I don’t have to start a serie, and with no BDSM things, just vanilla but exciting”.
I don’t really know anything about yaoi, so I wondered if any of you had any idea of some published oneshot who could fit this definition.
