Looking over my shoulder my wife was still asleep. I decided to get up and make some coffee. I poured my first cup and decided to enjoy watching the morning sunrise while I sipped on my fresh brew. I relaxed in a chair on the balcony, enjoying the fresh sea breeze and the distant cry of seagulls. I sat and sipped my coffee, watching the sunrise as it painted the sky with brilliant shades of red and orange, and fading into a crystal clear blue. What a beautiful day it looked like it was going to be. I found myself drifting back off into a daydream, wondering if Shelia was awake just above me, looking at the same sunrise. I suddenly remembered the last nights events, my passionate encounter with her. I licked my lips, getting a slight taste of Shelia's sweet sex on my tounge. For a second I felt a bit anxious, fearing I may have some signs of something on me that my wife would discover, revealing that something happened. I looked on my shoulders, and to my relief, there were no marks. I relaxed again, thinking I'd just take a shower in a few minutes. I continued to savor the taste on my lips. It began reminding me of the night before. I found myself drawn to thinking about the intimate details, the feel of her hands along my bare back, images of her arching her back as my tounge traced around the small of her back, her warmth against me. It was so intense and yet so painful to recall in the absence of her. I only wondered if she thought the same. I got up shortly after and took a shower and cleaned up. Later that morning my wife and I decided we'd head out to the beach early, so that way our daughter could spend more time in the sun. My wife was already ready to go. I needed to stop by the front desk, so I gave her my wallet and told her to go ahead and find an umbrella for us and get set up. Once I got things taken care of at the front desk, I headed out to the beach. It usually wasn't too crowded this time of day, so I didn't expect it would be too hard to find my wife and daughter. I looked over the umbrellas set up, and I saw Shelia under an umbrella not more than 20 feet away from me, with her daughter. What shocked me more is that I noticed that her daughter was playing with my daughter, and Shelia was talking to my wife! I became a bit nervous, not knowing how to walk in on this conversation comfortably. I also thought this was a chance to put aside what happened last night and work on us becoming more family friends, something that I really would like with Shelia, she was such a cool woman and mom. I wondered if Shelia had figured out who she was yet. I didn't know how she'd react once she did. "Over here Al!" my wife exclaimed, raising her hand. I saw Shelia turn around to see me, and she just grinned. I suppose she had figured it out. "Hey Al, I wanted to introduce you to Shelia. And this is another little Amber!" Amber, her little girl, offered her hand to me. "Nice to meet you Amber!" I exclaimed. Shelia and my wife seemed to really be hitting it off well. They seemed to have a lot more in common than just me. I was glad to see that they got along well, although it did make me a bit nervous. I didn't know if my wife would ever figure out what happened, and even moreso, I didn't know if I could hide my attraction for Shelia. I couldn't look over at her and feel comfortable. Looking at her in an outfit that reveals and accentuates her already gorgeous body doesn't really help me to divert my mind, but I play along. I thought this may be kind of fun, their conversation will be something that we talk about later on, after this vacation, as it was fun, just a little too tense in the present. "Say, why don't you come up to our room this evening Shelia?" My wife asked. I looked over at Shelia to see her biting her lower lip a bit. It was obvious she was contemplating it. "I really don't know if that's a good idea. Amber goes to bed pretty early." Said Shelia. "Oh, come on. It will be fun. We planned on just having a couple of drinks and watching a movie or playing some cards. It will be fun! And if you want, you can bring Amber over, and she can sleep in the room with our Amber. There are two beds." "Well," Shelia said, "I don't want to interfere with you guys time." I could tell she was pretty reluctant to say yes, especially concerned that this may not bode well with me. While I started out worrying about how this might turn out, I thought this might be really fun, knowing all the nervous tension, and I was ready to play along. "Oh, come on. We see each other plenty," I said, wrapping my arm around my wife's neck, just to give her a hug. I could see a small tinge of jealousy when I did it from Shelia. "Ok, I think I can manage." "Great!" my wife said. "Just drop in any time after 8." We soon left the beach. The rest of the day when I wasn't busy doing something I was thinking about the coming evening, and how awesome it was that we were all going to have an evening together. There were no two women who I would have preferred to be around, and we were far from home, so it felt a little more appropriate. Shelia arrived around 8:30. The kids played together for about a half hour before we put them to bed. My wife came back to the kitchenette and opened up a bottle of wine and all poured us a glass. We all retired onto the couch, with them two again conversing up a storm. It was almost as if I had vanished from the room. I started acting like I was sulking after a bit. "Oh, poor baby!" my wife said jokingly. "You don't have any friends, do you?" "No, I'll just sit over here bored, I'm fine thank you." I said back. My wife kidded back, "well Shelia might have talked to you if you hadn't been so visibly checking her out earlier." I felt my face flush. I was embarrassed by my wife saying this, and very nervous that I was noticeably doing this. I saw that Shelia's face flushed some too. "I'm sure you noticed, and I'm sorry, it's hard to keep him in line." "Oh, I didn't really notice," Shelia said. "But hopefully I could take that as a compliment." "Of course," I exclaimed. "Both of you are lovely." I could tell my wife thought it was kind of fun to point out my shifty eyes earlier in the day. They then got on the topic of men, and then onto the topic of sex, and men in marriage.... I thought it was a bit ironic that my wife was talking, almost complaining about sex and married men as was Shelia, although Shelia and I had some incredible sex just the night before. Shelia just went along with it, contributing her share of her opinion about the lack of excitement with her husband. The thought of these two women talking about sex was a bit embarrassing since it was down on men, but it was a turnon, although virtually everything Shelia said or did was a turnon for me. We decided to play some cards. We played Uno for the longest time, until we were all exhausted. "Man, I have got to get to bed" I said, looking at the clock make it's way around to 1AM. "Oh wow, I didn't realize how late it was," Shelia said. "I have got to get to bed. I don't know how I'm going to get Amber to go back to bed, she's usually up once she wakes up." "No problem. You can just sleep in our bed." My wife looked over at me for approval, and of course I was speechless. I saw Amber was visibly disturbed by this. "Oh, I'm sorry, I think I must have drank too much, I'm making no sense. I'll sleep in the middle, that way I'll be sleeping by my husband." I could tell that Shelia was not in a contesting mood, and didn't like the idea of waking Amber, and this sounded pretty safe, in theory. We all retired to the bedroom, and piled in under the sheets in the massive king bed, my wife in the middle, Shelia on one side, and I on the other. I decided since my wife was in the middle, it was no problem for me to sleep like I usually do, which is generally unclothed. Two minutes into laying in the bed, I suddenly started thinking about Amber being on the other side of the bed. It made it all the worst, still a bit dizzy and unhibited feeling from the alcohol. Visions of the night before began stirring in my head, and I didn't feel like I could resist the temptation of taking her. I began lightly dozing, recollecting all the details of the encounter the night before, and awoke a few minutes later to find myself breaking out in a sweat, I was so tortured. I knew I just needed to get over it. I rolled over to my wife, and told her good night and began kissing her. She seemed really receptive to the kiss too. Her mouth met mine, kissing me deeply, which I didn't expect. She made a really soft moan, and pulled herself up closer to me. It appeared that the combination of someone else sleeping in the bed and the alcohol had made her quite turned on herself. She whispered in my ear, "Do you think she's asleep yet?" "I don't know, has she moved?" "No," my wife said. I began unstrapping her bra, and reached down to lower her panties, so that she was lying there nude. I began running my hands along my beautiful wife, from the top of her thigh, across the small of her back, and along her side. I could feel her almost shudder with excitement. She continued to kiss me passionately. Then out of nowhere my wife froze. I didn't know why, but in the silence of the dark, I could hear a very light sweeping sound. I felt a hand brush over mine, and then I realized that Shelia was playing with her back, lightly running her fingers up and down it. My wife didn't do anything for a minute, and I could tell she was a bit alerted by this. Another minute or so later, she leaned forward and began to kiss me again, and after a couple more minutes of this, she began running her hands along me again, running her hands around the inside of my thighs, and tracing little circles along the lower part of my waist, teasing me. I could not believe that this scenario was unfolding in front of me, as I could see my wife was beginning to get really turned on by it, and obviously, Shelia decided she wanted to be involved as well. My wife had never been with a woman before, and as far as I knew, Shelia had not either. I knew they were both curious, but I wasn't convinced that enough alcohol had been consumed by either to make them brave enough to explore their curiosity. Again, my wife proved me wrong. I felt her roll over in the bed to face Shelia, leaning forward and pressing her ass up against my crotch. I felt her reach back with her hand and guide my cock up to her. She was soaking wet, more than I remembered her being since before we married, when we had some of our wilder moments in the dorms. I began pressing the head of my cock firmly against her clitoris, making slow circular motions. I could tell that you two were exploring each other with your hands, and the curiosity of what you guys were exploring of each other was really exciting to me. I began slowly and deeply fucking my wife from behind while Shelia and her explored each other. I could hear my wife making a muffled moan, and I realized that she and Shelia were kissing each other deeply. I suddenly felt Shelia's hand, rubbing my wife's clit and using one of her fingers to tease the length of my shaft as we continued this slow deep fucking. The combination of Shelia's hand with my wife felt totally incredible. I had to stop because I could not take anymore, and I wasn't ready to be put over the edge yet. I still wanted Shelia again. I could tell in the dark that my wife had gotten up on her knees. She made her way over to Shelia, laying on her back, and straddled her face. She pressed her swollen lips against Shelia's mouth, and arched back, ecstatic to feel Shelia's warm tounge fill her pussy. She began rubbing against Shelia's tounge. I felt bad, knowing how deprived Shelia had been. All this time, she had been kissed, and had been hearing and feeling my wife and I get pleased, and now she was being tortured by tasting the sex of my wife while she still lay there untouched. It appeared my wife was very busy, and probably was not concerned with what I was doing anymore, and so I begin running my fingers along the fronts and insides of Shelia's thighs. I could feel her grinding her hips upwards trying to get some relief from her torture. I could feel her cringe as I lightly ran my fingers along the outsides of her outer lips, realizing that the fabric of her panties was all soaked through and through, and she was making quite a wet spot on the bed with no sex. I removed her panties, and began making my way up from her feet, kissing and licking along her inner thighs. I could smell her sex, and it was driving me wild.... I began lightly licking along her inner thigh, and running my tongue in light circles around the outside of her lips. I finally made one long, slow draw up between her lips to her clit, where I began massaging it with her tongue. I could feel her wetness fill my mouth as I parted her lips. It was so luscious, I always loved to taste her. I felt her respond by driving her hips upwards and pulling my hands around to the back of my head, driving my face into her. I could not continue to take my own torture, the idea of my wife sitting on her face and her lying here this excited right in front of me. I lifted her legs up onto each of my shoulders, exposing her to me. I pressed the tip of my cock into her, and began thrusting slowly into her, but very deeply at this angle. She reacted by bucking into me, and moaning loudly into my wife's sex. My wife seemed to be too enthralled by the intense licking she was receiving, and just leaned back so that her head rested against Shelia's leg on my shoulder. We continued to pick up the pace, Shelia always felt so incredible, she was so tight, and I don't know if I had ever seen her nearly this wet or excited before. All three of us were moaning and gyrating into each other. It seemed like everything was spinning, it was more and more intense until I could contain myself no more. I could tell I was going to come. I knew I needed to say that I was and to pull away, but I wanted to be inside of Shelia too much to mention it. I clenched up and strained, thrusting myself as deeply as I could inside her. She felt me filling her up with my cum, and began orgasming simulataneously with me, licking my wife furiously, which caused her to begin coming. We all collapsed on the bed together, covered with sweat and our sex, just laying there in a kind of ecstatic daze. We all caressed each other to sleep. I couldn't even worry about what this would mean the next day, I was just too relaxed....
