We went cruising on the intercostal waterway. It was one of those party boats that take you out far enough to gamble in their casino. They devoted two whole decks to poker, blackjack and craps tables as well as a roulette wheel, but most of the space was devoted to one-arm bandits in fact the perimeter of both decks was surrounded with them preventing any view outside. My guess is that would slow down the gambling. Everything was geared to get you into the casino and keep you there. To get a drink you had to go to the bar in the casino and all the restrooms were on the casino decks. The small dining room was on the bottom deck but there were endless buffets on, you guessed it, the casino decks.
Janet and I planned to enjoy a leisurely dinner in the small dining room. While we were waiting for a table for two we met another couple that suggested we sit together since four tops were readily available. They were very nice and we enjoyed their company. After dinner we all went to the casino. Fred was really into poker but Beverly and Janet preferred roulette. I stayed with them until our chips ran out. Janet and I decided to go up to the observation deck and Beverly asked to join us.
The deck was nicely decorated with easy chairs around the outside. There were two open chairs so Janet pushed me onto one and she sat on my lap. Beverly sat in the other one with a small table between us. I brought a bottle of wine and we watched the distant Miami skyline as we sipped it and listened to the music from a piano player. Janet and Beverly are both beautiful. They were wearing cocktail dresses with high heels; that always turns me on like crazy. I couldn't keep my hands off Janet; I began caressing her knee soon after she sat down. My fingers wandered up her beautiful legs and I was pleased and surprised to discover that she was not wearing pantyhose. When my fingers touched her warm bare thigh I got an immediate erection. She knew Beverly couldn't see what I was doing and she gave me a sly little smile and spread her legs just enough to let my hand reach her crotch. My heart almost stopped...she wasn't wearing panties. My fingers caressed her soft warm pussy and then I slid them into her cunt. I rubbed her clit with my thumb and she became very wet. I put my wet hand to my mouth and licked my fingers then returned them to her sex. When she climaxed she whimpered softly and flooded my hand even more. I wanted to put my head under her dress and eat her but Beverly's presence as well as the crowd of tourists prevented it. When I pulled my fingers out this time I dipped them in my wine glass and licked them clean. I almost came in my pants.
Apparently Beverly didn't miss our little performance. When they went to the restroom she told Janet she was jealous because Fred was so into the casino that he would never leave until they shut it down to return to port. By the time they got home he would be so drunk and exhausted he would fall asleep and she would have to take care of herself.
When they returned Janet told Beverly she could only take so much of my bony legs and asked, "Do you mind if we trade places for a while?"
I don't know who was more surprised but Beverly agreed and sat on my lap. Before Janet sat down she leaned over to kiss me and whispered, "Do her." I looked up very confused and Janet gave me a smile, dipped her fingers in my wine glass and licked them. The message was clear but I couldn't believe it. This was not my wife; someone must have taken over her body.
As we enjoyed the music, view and conversation Janet kept looking down at Beverly's knees and then at my hands. I understood her signal but I was hesitant to do anything. Finally I decided to try and I casually rested my hand on her knee. Beverly got a panicked look but she didn't pull away, she turned to face Janet who gave her a knowing smile and a barely perceptual nod of approval.
