It was a very hot summers day. Elle had a friend who lived near the beach called O. O was a very free spirit who had few inhibitions. She was quite slim and Elle had used her as a nude model for life painting. We went over to O's place and, as it was hot, we were wearing our swimwear under our clothes. O greeted us wearing a flimsy dress and as usual was braless. We went into the rear garden and stripped to our swimmers. I was wearing some Speedo briefs and Elle had a sexy one piece. It was g-string style with a plunging neckline. It was also cut very high on the hip and narrow at the front and barely covered Elle's pussy. We had a few wines and decided to cool down by spraying some water over each other. Once Elle's costume was wet it became see through. Her dark nipples were very noticeable and pushed through the thin fabric. We knew we were free to be uninhibited. Elle came and sat on my lap and aroused me. My hard cock was restrained by my swimmers and was close to her vagina. We were feeling adventurous so we said to O we wanted to go naked. This didn't worry O at all so Elle and I stripped our swimwear off. We were now nude. When O saw us, she said she would join us. She removed her flimsy dress and revealed her small breasts and dark nipples. Then O took her knickers off so she also was completely nude. Elle and I were feeling horny so while O was off doing something in the house, Elle came and sat on my lap again. She began rubbing her vagina lips on my firm cock, It aroused both of us further. As we were exhibitionists the next step was inevitable. Leaning back, it was easy for me to push my erect cock into her wet vagina. We were fairly uninhibited now, as the wine was going to our heads so when O came back out, we remarked we were enjoying having sex. O loved the idea. We loved being watched and had plenty of experience in past swinging meet ups. We made sure we kept eye contact with O, drawing her into our pleasure. She watched us rocking back and forward slowly fucking, then started to play with her nipples and arouse herself. Once it was clear that O wanted to join in, we got up and moved over to her. Elle enjoyed having sex with other women and had often expressed a desire to hook up with O and now it was happening. We began to massage her body and breasts which she totally enjoyed. Then we began to suck on her firm nipples, one of us on each breast. I knew Elle and O would get into it. Elle was very good with other women's clits. The only thing that we hadn't discussed was what to do if O wanted me to fuck her.
We were just getting into a threesome when we were interrupted by the phone ringing. It was a friend of O's. O, who also was tipsy, told the woman she had friends over, that we were naked and were going to have sex together. O then asked if she wanted to come over and join us. The answer was yes. O said she needed to go and pick her up. It wasn't long before they arrived back. The woman stripped to her racing swimsuit and soon she had also bared her breasts. They were a rounded with firm nipples. We knew she was same sex attracted so Elle went over to her and they began to play with each others nipples while I watched. Our get together was getting very sexy.
Our newly arrived friend was beginning to feel the heat, so despite the fun she decided to go home. The party slowed down bit but later, after it was dark, the three of us went to the beach and had a skinny dip. O said she had enjoyed the romp. She also remarked that earlier, when we were caressing her, she really felt like having sex with us. The moment had passed somewhat but we enjoyed it when it was happening.
