Looking for a story

Hi all. I remember reading a story a long time ago. Probably 15 years or so. I thought I had it saved but I must have lost it at some point. After trying for a long time to find it with searches on google and other avenues I am asking if anyone has read it and knows where to find it now or if they have it saved and would not mind posting or sending in PM.

I found it on eroticstories.com, before it was a pay site. It is no longer there, even on the archive. I have looked.

The story is called, "Lisa's Charity Work" and is about a wife that goes with a friend who is a social worker to check on a case. She ends up having sex with two men and letting one of them cum inside her.

I can almost remember it vividly enough to rewrite it myself but would not want to do that to another writer's work.

Any help in finding this story would be greatly appreciated.
