Can’t find this wife business trip story

[Hockey1993]

Story about a couple. Can’t remember if they were married or not. Wife’s boss was leaving the company and asked her to join for his last business trip with intention of sleeping together. Wife admits to husband she’s thought about it and would like to go to live out the fantasy and she would come back to him after and nothing would change. Husband reluctantly agreed. Wife goes but she’s also planned for her best friend to stay with her husband for the duration of trip. I read this story k the last year but I can’t remember when it was published. Any help would be appreciated thanks.
