We are all different but there are a few things that always turned me on. First my exwife was my best friends primary sex partner while we dated and also married. She openly screwed many of my friends and coworkers but it was only guys that he liked and approved. She never asked for my approval but would never do anything with another guy without his OK. He also liked her to dress sexy when they were together and he loved to see her hard nipples under a thin tank top. We went to his grandparents lake house many weekends and they had a nice boat. He would always ask other guys to go because many of them waterskied and it was not uncommon for him to have her take her suit off of the guys to enjoy. He would have her give blowjobs to some of the guys and he would sometimes send her below deck and screw a guy just to show his dominance. She loved this treatment and could not get enough, many weekends I had to work and was not able to see this first hand. I would meet them after I would get off work and I loved being in that situation where these guys knew she was my wife but was my best friends plaything.
