I was a Marine at Camp Pendleton, CA in the late 70's-early 80's, and worked as a bouncer/security at several dance clubs/meat markets at night.
Marine units rotate in six months increments aboard Navy ships, out of Pendleton to the Western Pacific (WestPac), and out of Lejeune to Europe, the Med and the Mideast.
When a unit either deployed or rotated back to the States, the turnover in the clubs was significant, especially among the women, as when a unit deployed a totally different group of women would be in soon after, some wearing their rings and some not. Service wide we called them Cruise Widows, and out of Pendleton we specifically called them WestPac Widows.
My buddy's unit deployed several weeks ago, and the new crop of women were starting to show up. It was a Friday night and I was not working the door. All at once I noticed four hot looking women come in and get a table near the dance floor. One of them was Steve's wife, and they were getting and giving attention to some young studs. I watched the play and seduction going down, and at one point, Ellen, my friend's wife, exchanged whispers with her new guy, and headed to the bathrooms. I intercepted her and she begged me not to tell her husband Steve. I said no problem, but follow me. I took her to a door and said, If you want to give your boytoy a blowjob, or even fuck him, take him in here, but do not take him home. Steve would not like it. She looked at me strangely, and I told her we need to meet for lunch tomorrow and I have things to tell you, things to show you, and something for you to listen to.
Unbeknownst to her, Steve had poured out his heart and his fears to me, and we crafted a plan to alleviate those fears. Like all first time guys going on a six month cruise, he was worried about his wife being lonely and cheating on him, though in reality, it isn't the cheating that was the real issue. It was her being lonely, having an affair and falling in love with another man, and kicking him to the curb while he was at sea and unable to fight for her. So he asked me to watch over her and keep her safe. Because he was concerned about gossip, he and I rented a furnished apt with maid service on a six month lease.
