In the privacy of our room we immediately undressed and showered. It felt good to feel clean and fresh again after a day in the sun. I opened the patio door and to let the fresh sea air fill the room before I crashed on the bed and relaxed for a minute while Mary finished in the bathroom. I expected her to do the same but was a little surprised when she put on her short satin robe and walked toward the patio door and opened it. The robe struck me for its similarity to the one I had seen Lynn in earlier in the day. Except for the color, Mary's was aqua blue; I could have sworn it was the same robe.
Mary stepped out onto the patio into the warm Caribbean air and gazed up at the sky; she looked deep in thought as I approached her from behind. I startled her from her day dreaming when I touched her shoulders. "I'm sorry; are you ok, Honey?" I asked softly.
She turned to me, reached up and pulled my head down to hers and kissed me deeply, searching my mouth with her tongue. This was so unlike Mary, she almost never initiated anything like that. When she finally let me up for air, I looked at her gorgeous, smiling face and answered my own question, "Yah, I'd say you are ok!"
She loosened the tie of her robe and let if fall open before pulling my naked body close to hers and then reaching up to kiss me again. As we ground our bodies together my cock began to stiffen against her. I could easily get used to this more aggressive version of Mary. We could hear soft mumbled sounds from next door and realized that Rob and Lynn's door must be open so we kept our own sounds to a minimum. I just wanted to be with her right now.
Mary whispered in my ear, "Let's go see what they are doing."
I couldn't believe this was coming from her; that would normally be my line and she would normally tell me I was a pig. I whispered back, "I think I know what they are doing."
"Let's just go take a peak." Mary took my hand and tiptoed to the end of the partition dividing the two patios. I couldn't believe what was happening. Of all the suggestions I had made over the years to Mary about watching, being watched, or even my ultimate fantasy of watching Mary with another man; she had always been turned off and didn't even want to discuss them. Now she was the one making the suggestion. I thought about how I had worried that bringing our friends along was going to ruin the sex we always enjoyed on vacation but this was better than I could have imagined.
We cautiously poked our heads around the end of the wall until we could see in the sliding patio door next door. The lights were on in the room and the drape was pulled all the way open, as was the door. We could clearly see Rob and Lynn on the bed, their feet pointed slightly toward the open door. Rob's head was propped up on the pillows and Lynn's head was resting on his chest while she teased the area around his cock. She was obviously taking great delight in his reaction to her teasing as his cock twitched and bobbed, the tip occasionally brushing her hand as she moved it about.
"Please," he begged. But instead of giving him what he wanted, she lifted her head from his chest and asked, "Please bite?" as she bit down gently on his left nipple.
As my cock twitched on its own at the site of one of my favorite erotic pleasures being applied to Rob, Rob said, "Ouch, no, that's your thing. Please touch my cock."
Lynn laughed as she put her head back down on Rob's chest and said, "Oh, touch, ok," as she placed her fingernails at the base of his cock and slowly, gently scraped them up the bottom side of his cock all the way to the head; his cock twitching spastically at the torture.
When I moved back slightly to our side of the partition, I could see Mary's face from the side as she continued to stare at our neighbors. Her eyes were wide and wild as she stared at the sight of her friends playing less than fifteen feet away from her. She had watched plenty of porn movies with me over the years but she had never seen another man's erect cock in person. Rob's cock is not as long as mine but it is thicker; Mary has always loved looking the different shaped cocks in porn movies, especially the big black ones.
I moved back behind her and nestled my cock in her back as we watched. Mary inched a little further beyond the end of the wall so her upper body could have been seen from inside the room. I followed behind her, holding onto her waist, using her as a shield to hide my stiff cock poking her in the back. I must admit, I felt a little strange watching our friends without their knowledge.
When Lynn finally gave in and grabbed Rob's throbbing cock, he lifted his head to watch her jerk him off. He was smiling and obviously enjoying the hand job, then lay back down and on the pillow and pulled Lynn's head toward him seeking a kiss. They made out in this manner, Lynn never losing the rhythm on his cock.
Lynn smiled at him and then lifted herself up on her elbow as if to get a better view of the cock she was jerking. Her eyes darted quickly to the open doorway and then back at the cock. We froze in fear that we had been seen but were afraid to step back or move at all for fear of being caught.
Without letting go of Rob's cock, Lynn got up on her knees and then said to "Eat me," as she lifted one leg over him and lowered her pussy onto his face. She was now facing almost directly at the open door and was using both hands to jerk off her man and massage his balls. At the same time, Rob reached up, found Lynn's nipples and started playing and pulling them roughly, just as she liked.
Mary's hand had moved to her wet pussy and she was playing with herself at the edge of the patio, now almost completely visible from within the room. I was standing behind her and had opened her robe completely so only her shoulders were covered, her entire front on display as I massaged her tits and rubbed my cock up and down on her back while I watched the show.
Rob pushed Lynn up and she un-straddled his face as he said, "Your turn to lie down," loud enough to be heard outside.
