True Story:
A lady worked at a MP in town where they have pics of the girls , and the client picks based on that......this lady had her face somewhat obscured in the pics....anyhow a guy picks her, and is shown to the room by the front desk girl. So the lady walks into the room....and here its her BEST friends hubby.....both kinda freak out ...and she immediately runs off to front desk , and says I think theres been a mistake.....go take him the book and he will pick someone else !!..receptionist takes the book of pics into the room ..but guy is freaking out....and asks for original girl to come back to talk....so she goes back...and both are like OMG don't say anything to anyone etc etc.... finally both settle down...all is ok...and then he says well why dont you stay....and she does....and they do their thing........after that she felt so guilty towards her friend....she quit going over their etc...and basically it broke up their friendship , cause she couldn't look her in the eye....or was extremely uncomfortable if hubby was around.....had she told her friend..it would've been the end of their friendship anyhow..plus would've broken up the marriage. She said that was one of her biggest mistakes she ever made , was to agree to sleep with him, thinking it won't hurt.
Long story short......things can get complicated in a hurry!
Bottom line...everyone has a choice.......just making the right choice sometimes is difficult!
Had an SP tell me a similiar story.
She was one of Wpg's great Indy ladies. One day this guy comes to see her and she opens the door and its her daughter's softball coach and the father of one of her daughter's friend's on the team.

Went through with the session but she said it one one of her most uncomfortable ever.
As well from that time on, when she took her daughter to softball she would just drop her off and sit in the car or sit far away from the other parents and watch. She was too embarressed to see him and couldn't sit there, near his wife, pretending nothing happened.
A situation like this can more often than not, be very uncomfortable for the lady.
Remember these ladies are human beings, not robots and as sexually liberated as we all think we are, many have fears of being outed to those in their real lives.
In this case, respect this young lady's privacy.
Cheers.
