I've also been looking for a long while, and I didn't get much of a response the last time I asked on here. It's a bit of a dangerous line to walk, and there's not a lot out there from my experience. Ao3 has some, but I wasn't completely happy with their quality. Your best bet is to fire up the Internet Wayback and dig through the ASSTR archives. If pure debauchery is your thing (it's not mine), Frank McCoy did a lot of short stories in that vein. I'll also mention the works of AnonyMPC, who does a few different styles. I prefer his slower burns. They also post their stories on 7chan, though I don't think all of their stories are there. Good luck to you.
