I've seen this pairing! Unfortunately, I can't remember where! :(

I once came across was some enjoyable Ten/Tosh smut involving recreating a scene from a hentai movie, but I don't remember the title or the author and I don't know if they've written any other fics with that pairing.
*tries to beat the info out of my brain*

If I remember more I'll post - but that may be enough clues for someone else to find it. Good luck!
