Carrie had taken the lead and had her head buried in Jeff's crouch. She massaged his balls with her left hand while holding his cock in her right and licked it like it was an ice cream cone. I whispered to Susan that Carrie must find that to be tasty and I hoped she would like some dessert when we got back to our cabin. They progressed into 69 position on their sides and Carrie had one knee bent up and was getting her pussy well tongued while he pulled her cheeks apart as if to give the four of us a better view. Carrie said that she wanted some cock in her and rolled over on to her knees and elbows and Jeff fulfilled her request. It was one hell of an exciting picture with her stroked from behind which made her breasts move in rhythm. Jeff reached under her and started rolling her stiff nipples between his thumbs and forefingers and using her breasts for leverage as they both proceeded to climax together. They both fell forward collapsing onto one another on the bed.
The rest of us got up and moved around as if nothing unusual had occurred and proceed to the bar area for another drink. My cock wasn't fully erect but it was showing some signs of life. Susan and I both noticed almost together how Ralph's large cock had some moisture on its head and it hung quite low. Susan and I stayed close together having never experienced anything like this. I did look at Rhonda's breasts and lush mound at every available opportunity, which were numerous because of the cabin arrangement. The total reaction was no more than if we had observed friends enjoying an exceptionally close dance. After about ten minutes Jeff and Carrie reappeared and sought out another cocktail as if they had excused themselves to reclaim an item from the dinner table. The conversation continued and again Rhonda asked if we were offended. We both nodded of no. We all ended back on the veranda and now Ralph was openly affectionate with his wife. They seemed to follow the same pattern as Jeff and Carrie. They proceeded to excite each other with overt attention. Nothing had been uttered but both Susan and I admired our new friend's bodies. Ralph's cock grew both in length and girth and Rhonda's exceptionally thick black pussy hair combined with her shoulder length black hair became even more strikingly sexual.
Although I have always preferred written erotica over visual, the most exciting pictures to me have women with very thick dark mounds trimmed neatly in a triangle. The clean shaven pusses we now see so often on the net remind me more of plucked chickens ready for roasting instead of being the sexually exciting anatomy of a mature woman.
While not four feet away from us, Ralph fell to his knees and put his face against into Rhonda beautiful pussy and began licking in earnest. She reacted by taking a hold of his head and moving her feet apart. Next Ralph stopped kneading her beautiful ass and moved his hands to her breasts for some serious nipple play. They slid onto the adjoining bed and she gathered up his huge cock and started to but it in her mouth. Susan and I looked at each other thinking no way was that large cock going to get into that small mouth but we were wrong. She attacked his cock head with vigor. We could tell that her tongue was swirling around the top and occasionally stopping to penetrate his slit. While we watched this unfold I took Susan's hand and put it on my cock and put my left arm around her and attempted to reach her left nipple. During this time Jeff and Carrie stood nearby watching as if it was an everyday occurrence. In a perfect world Susan would have started to nibble on my nipples and we would have ended up on the bed next to them but that was not going to happen.
Ralph ended up on his back and while continuing to use and abuse her nipples. She with some effort proceeded to slide down on this huge cock. Of course she had been there hundreds of times before but she was cautious and the penetration proceeded slowly. Watching that cock slide into that beautiful pussy was one exhilarating picture. She rode him with vigor and her eyes closed and her breathing increased and as they both neared orgasms. Within a very few minutes it occurred and she became very vocal calling 'fuck me, fuck me, fuck me'. That verbal exchange was lit my fire as that was never been a part of our sex life. I thought I was going to cream the carpet when she reacted that way. I knew Susan sensed my excitement with those events but it occurred without comment between us.
What occurred next was the most unusual thing we had seen so far. We thought we knew about marital sex and its variations. We were about to learn something new. Without an utterance Rhonda moved off his now shrinking cock and got on her knees and elbows. Ralph slid down the bed and put his mouth under her pussy lips which were then about three inches away. She senses that his cum was starting to drip form her pussy and she sat upright on her knees. When the flow of cum became significant and gravity forced her to drip he moved his mouth up to her pussy and proceeded to lap and suck as if that was the only source of life sustaining liquid available and it must all be consumed in order to survive. Susan and I looked at each other as if to say I do not believe what we just saw. I had always wanted her to suck and lick my cock after it had shot in her so she could taste our combined juices but that had never happened. Similarly I had never considered sucking my cum from her but all of a sudden that became something I wanted to try later that evening. Both couples had 'cleaned up' after sex and we all stood around the veranda and watched the stars and listened to the soft music and the ship cutting through the sea. Susan and I both sensed that they expected us to follow their lead but that was not to happen. Our vacation relaxed brains had been exposed to an overload of sensory imputes for the past sixteen hours. We needed to regroup and digest the day's events and determine where our combined limitations, goals, and values might lead us.
Thinking only in the very short term I could not wait to get Susan's robe opened in the elevator but put my face in her pussy as Ralph and done to Rhonda earlier. Further I was looking forward to tasting my cum as I lapped and sucked it from that tight glorious pussy. I was not disappointed. Susan was as turned on as me. Sex that night started before we reached our cabin and did not stop until we were both exhausted hours later. My last thought that evening was I hoped that this was the start of a Renaissance in our sex life. Little did I know that this was the start of a sexual tsunami that would bind the two of us together more closely that we could have imagined. My unmitigated, unwavering total love for Susan had reached new dimensions.
