I do security at a swingers club. It’s very common for this sort of thing to happen. Many of these women are very lonely and you’ll be amazed how many men like to see their wives go with me (with their consent) as soon as they find out I am a personal trainer with incredible stamina.
Conversely there many women out there in loveless relationships who have a one night stand with me just for company and a good seeing too. I have often wondered why don’t more men spend time with their wives.
