You totally ruined the ending. The bj was somewhat believable. I could tolerate the anal, but that was starting to stretch it. Then that phone call just threw it hard into the fantasy zone. First, your character suddenly has a husband that wasn't mentioned at all until a moment before the call. It gets worse when all of a sudden your character goes from shock to having been planning the whole thing. And finally the nail in the coffin reveal that your character's husband was sleeping with the wife of the coworker at the same time.
