Wife gets off on husband's exhibitionism

[Fantasies-only]

The voyeuristic tail of permitted visual cheating got me so hot, we definitely need some more like this!
Unfortunately I forgot the title, link, and author, but I have to say, it was nothing like I've ever experienced before!

I could do without the 2 girl threeway.
I think it's more erotic if the husband just watches his wife with another woman, or 2 women.
Put in some steamy (pun intended) shower scenes as well.
As you can guess, in homo-eroticism, I'll take F/F over M/M any day.
If 3 women are used, make one not so mature yet, but not prepubescent.

I think the guy should be jerking off helplessly while watching the two women get each other off with no interest in him joining in.

I'd like to read this story. Can you remember he thread?
