I read a cuckold fic a long time ago that I enjoyed but can no longer find. It was in one of the cuckold forums, not reddit.

The main male lead B and the main female lead A were on a honeymoon after just getting married. A bunch of guys challenge B to a game of pool, where if B wins then they get something (money?) but if B loses then they get to do whatever they want to A. B is quite good at pool so he accepts the bet, but loses unexpectedly. The rest of the story is B being forced to watch A get gangbanged, and A is initially terrified and humiliated but gradually starts to enjoy it. You know, fairly typical cuckold plot, but I seem to remember the writing quality being quite good.

I kinda wanna say B's name was something like Bill, and A's name was something like Amanda, but I wasn't able to find this fic in any forums after some googling. If anyone is able to find this story, I and probably many others in this sub would appreciate it!
