Trying to find very interesting story (reluctant, swingers, cuckold, ir)

I am looking for this story for a while now, it is a story where a husband describes his vocation I think in Vegas, where he and his wife met another couple who took them to a swinging club or something and they all got drugged and he ended up watching his wife get fucked by some foreign guy who was following his wife the whole night.

That guy didnt speak english well and ended up cumming inside wife unprotected. I think that the title of the story is only one word, and its something wierd that the foreign guys says to a husband before cumming in his wife, I might be wrong about that tho.
The story is from literotica probably

If anyone knows the name of the story it would be soo cool if you could tell me or share a link in comments.
