It was September last year when I first met Rebecca and Tony and our relationship really came on well over the winter. Begining as me simply watching a young couple fucking, Rebecca is just 19 and Tony 21, me a young st heart very early 60 something, she was now giving her body to me along with Tony. All three of us are having fantastic sex every time they come over, which usually is about every 3 weeks or so. I am an Englishman living on a Greek island, Tony and Rebecca are both Greek. In the middle of february this year we celebrate Carnival. For a whole week there is a fantastic party atmosphere in town culminating with huge parades on Saturday evening and Sunday afternoon, with Monday being a public holiday. Rebecca and Tony were going to arrive late Thursday evening after work and stay over until Monday afternoon. This was going to be our longest stay together and also the chance to move our relationship outside the bedroom and into the open. It was nearly 10.00 in the evening when they arrived, Rebecca had been at work until 8.00. Although tired they were both very excited about our weekend ahead. We ventured out for something to eat and it was almost midnight when we returned home. Conversation had been buzzing and lively as we ate our meal. Rebecca as always looked stunning wearing a tight pair of jeans with a red V-necked sweat shirt. Braless as always I could make out the shape of her nipples against the materiel, and whenever she lent forward thee was a tantalising view down her cleavage. We sat at a round table in a corner with a rounded bench, Rebecca in the middle. There was plenty of touching underneath the table going on between us all, I got a lovely feel of her pussy between her opened legs and could feel her getting damp below. Rebecca went to the loo, being fair to us both I saw Tony having a quick feel of her body as she slid past and when she came back she came in via my side so I could do the same. I also noticed she had left the zip on her jeans undone getting a clear view of her red panties underneath. Once sat down I could slide a finger inside her jeans but little more. Our conversation had been great, recounting the adventures we've had together so far and looking forward to the weekend. It was after midnight when we arrived back so it was pretty much straight to bed for us all. As we all undresed and slipped under the duvet together, Rebecca naturally in the middle Tony and me took it in turns to make love to her before falling asleep. Friday was pretty much a lazy day. We went for a stroll along an almost deserted beach, far too cold to go for swim but warm enough for just T-shirts. The breeze making Rebecca's nipples really stand out firm. At one stage we all stood in line close to the water, Tony and me both had our cocks out while Rebecca massaged them for us. As there was nobody in sight we didn't bother putting them away as we made our way back to the car. That night we had great sex all together. I did notice Tony seemed to accidentally touch me a few times, more so than previously. As he did I looked Rebecca straight in the eye, at that point she gave me one of those deep passionate kisses she's so good at nodding her head as she drew away. Then, as Rebecca went to go down on my cock, Tony got hold of it and guided it into her open mouth cupping my balls as he did so. As we went to change over I returned the favour, they both seemed pleased. As the bight drew on there was some more mutual touching. Once again Tony cleaned Rebecca's pussy of our sperm, then kissed her snowballing it between their mouths. Next morning while Rebecca was showering Tony asked me if I was comfortable with what happened last night. I said I was and it felt OK in a threesome situation nut i wouldn't want to do it on my own with just another guy. Tony said he felt the same and we could explore some more. Turns out Rebecca had been the first to raise this with Tony, she saw it as being us all together as a three part of enjoying each other fully. When she emerged from the bathroom Rebecca came straight over to us, her towel slipping off her body as she put her arms around us both and we all stood there arms around each other in a passionate clinch. We enjoyed the carnival parades, standing close together in a large crown there's plenty of opportunities to grope one another which we did as much as we were able. Friday and Saturday we had the most wonderful sex all together. Rebecca pulled our cocks together then put them both inside her hot mouth. It was strange to feel another cock against mine but a real thrill at the same time, and of course wonderful to see them both squeezed into her mouth. On Saturday night after we had both come inside Rebecca I ventured down to her soaking wet pussy to clean out both our loads of sperm. With a mouth full of the stuff I went up to Rebecca's face and kissed her on the lips forcing the contents of my mouth inside hers. We pushed it back and forth between us then gently pushing me to one side transferred the contents into Tony's mouth then he back to hers before finally swallowing it all. On Sunday night, our last together, Rebecca was giving me oral sex when she pulled Tony's head down to and they both did it too me together. Rebecca clearly wanted this and although a little uncomfortable to begin with I lay nack and let it happen. She looked so pleased seeing this that it came almost naturally when roles were reversed and she pulled my head down close to her while giving Tony oral sex. Our lips met either side of his cock as we ran our tongues up and down before coming together at the tip. So, in the space of just over six months from first meeting to satisfy my voyeuristic likes to watch a couple in their intimate moments we had now become a fully fledged bisexual threesome. What else could we do?
