My wife and I have have many sexual experiences with multiple partners but whenever we have sex with others we are always together. There was one time when I was away working and my wife fucked Tom on the webcam but I was still watching at least. On a recent holiday in Tenerife, we decided that we would go to the roof top naturist bathing terrace, even though we had not done this before. It was a bit strange at first but once we had removed our robes and settled on our loungers we were fine. One of my fears about these places is that if there was an attractive woman there, I would end up getting hard on! However, most of the other people there were older and a bit saggy so I had no problem........at first. After a little while another couple arrived and took the loungers next to ours. They were about our ages and when the woman dropped her robe it really did make my cock jump. She was quite tall, slim and had a great pair of firm tits. Despite her long blonde hair, she had a dark thick bush of pubic hair. I had to turn onto my front, close my eyes and turn my ipod up just to try and stay in control!! I must of dozed off and the next thing I remember is looking up to see my wife chatting with this couple over drinks. "Hi sleepy head" said my wife and went on to introduce Peter and Judith. They were Danish, both school teachers and regular naturists. I was finding it hard not to stare at Judith, with my eyes passing from tits to bush and back. Her face was quite plain but, wow what a body. We passed the day bathing, drinking and chatting and arranged to meet for drinks after dinner. As we were back in the room getting ready, my wife commented on how much I had been staring at Judith but far from being annoyed she went on to say that it was okay as long as I didn't moan about her looking at Peters cock. "I like the way he has kept the hair tidy, maybe even shaved his balls, and how the foreskin kept moving back just enough to see the tip" she explained. "I wonder if they are into swinging as well as naturism?" I pondered "Nah, they not the type" replied my wife. She is normally a good judge, but not this time. We met as arranged and ended up with the two wives talking to each other, while Peter and I chatted about football, cars, etc etc. Out of the blue Peter said "you like my wifes body then? I saw you staring today you dirty bastard." I stuttered as I tried to reply, "I I I I'm sorry, I didn't mean to offend anyone." "That's okay" Peter said, "she has a great body so I don't blame you. I am a lucky man as she is a very good fuck too. What about yours?" "What?" "Well your wife has a great body too. What is she like in bed?" I saw the opportunity for a foursome developing and took it. "She is very very good. I have no complaints and neither do any of her other lovers." "Ah I was right" said Peter, "you are swingers. I thought so but just wasn't sure at first" At this point Judith piped up, "and what are you two talking about?" "I was just saying what a good fuck you are" said Peter, "but he thinks she is better" he continued, looking at my wife. My wife looked at me a bit shocked but I gave her a little wink and that brought a wide smile to her face. If this did develop, she would be up for it. "Well we must settle this argument once and for all", said Judith "right now!" and with that she stood up, followed quickly by Peter. Peter then asked which room I wanted to take and added that he and my wife would take the other. I looked at my wife as we had never done this before and she just said, "I'll go to our room with Peter and you go to theirs." then headed for the lift. When the lift stopped at the 3rd floor and she went to get out, I took hold of her hand. She looked back at me and said, "it will be fine. You go and enjoy yourself, I'll call the room later." She smiled and leaned over to kiss me. As she did, she moved my hand between her legs and I got a feel of her hot wet pussy. She was obviously very horny. Judith and I stayed in the lift until we got to my room. Once inside, Judith stood to face me, took both my hands and said "don'y worry about her. Peter is a very good lover and not at all rough or anything like that. She will enjoy herself. Now what about you?" and with this she put my hands on her tits. My cock was up in an instant and I pulled her towards me and could feel those firm tits against me. We kissed with passion and then pulled apart and stripped off in a hurry. Judith pushed me onto the bed and crawled on after me. She took my cock on her hand and started to kiss up and down its length before taking me into her mouth. As she sucked and licked, she turned her body so that her pussy was right above my face. I looked at it and stroked it for a while, feeling the slippy wetness, before lifting my head so that I could get a taste. It was fantastic, musky - but sweet too. I was soon well into it licking and sucking on her pussy lips and clit. At one point as I sucked hard on her clit, she took me from her mouth and said "yes, like that, it will make me come", so I sucked hard on her and sure enough her body shook as she had her orgasm. She rolled off me and lay on her back. I lifted up and looked at her body. It really was fantastic. I had to fuck her. I climbed up onto her and took my weight on my arms. As I moved my cock towards her opening she took it in her hand and began to rub the length of her slit with it. Gently at first, then gradually harder and faster until she was really wanking her pussy with it hard. Her eyes rolled and she moaned as another orgasm went through her. "You will make me spunk doing that" I said, but she continued to rub hard, coming hard again. I then thought how good her body might look covered in spunk so I took hold of my cock and wanked over her. As I began to cum, cock stiffening in my hand, belly turning, she pushed fingers up herself. The first squirt of cum fell in a line across her left tit, the second got her on the chin and the next fell onto her flat hard tummy. There were about 6 or 7 squirts of spunk over her and it did look fantastic. As I collapsed back on the bed, Judith started to rub the cream into her body. "I love this" she said, "I love the warm sticky you get from spunk on your body" For the first time now I thought about my wife and what she might be up to. Her favorite is to have the spunk up her and I wondered if she was getting it. "God that was quick!" said Judith as she looked at my already stiff cock. She climbed up onto me and slid her pussy onto me. God she was tight, wet and hot. She was soon riding me hard, panting and squealing. Her tits were bouncing and I put the flat of my palms over her nipples to feel them rubbing. Her pussy tightened as she came on me (not my doing, she was doing all the work)and the squelching sounds told me it was a very wet cum. Soon my cock began to twitch again and I came inside her this time. We lay for a while and soon after the phone rang. It was my wife asking if I was okay and saying that she would be "home" soon...after one more fuck!! Judith and I also had another go, this time with me on top, her legs around me, tits hard against me and our mouths kissing passionately. Not long after we both came again, there was a knock at the door and I opened it to see my wife and Peter. Judith put on the robe Peter had brought and they left. It was now almost dawn and my wife and I lay cuddled up on the bed naked. "you want to tell me about it?" I asked her. "Oh I will", she said, "later. But just so you know, he wasn't better than you, just different. I learned some new tricks that I will show you later too." And she did. But that is another story
