So, this recollection happened back around Christmas while my SO and I were visiting his family. Typically when we visit them the house provides enough distance between us in the basement and his parents upstairs that we can engage in sexy times without being heard (so long as I can keep quiet). However, more family members were visiting and thus more room was taken up in the house, booting us onto an inflatable bed in the living room. On this holiday, I had to work longer than him which ment more days apart and added to the sexual frustration we both had.
Fortunately, the family had some things that needed to be purchased at a large retail store. Naturally, my SO and I offered to go get needed items being helpful people that we are. While in the car we conversed on how we could relieve ourselves, and playfully mentioned doing it in the changing room at the retail store. I casually mentioned that I wanted to look for some fuzzy sweatpants, and thus would need to go into a dressing room anyway so … why the hell not?
