We were spending our third anniversary of swinging together on this sun-drenched Caribbean island. It was wonderful-sensuous moonlit tropical nights with the surf lapping at the shore; days around the pool and hanging out at the beach bar. It was intoxicating. Now we were in our cottage with the stranger that we had met at the bar. You and I had become acquainted with him when we were enjoying our rum drinks, and found him pleasant and charming. We invited him to join us for dinner, and he readily accepted.
While we were showering and dressing for dinner, I remarked that you seemed attracted to him. You blushed and said not really but that wasn't quite true, and I could tell by the state of your nipples as you got ready. After Keith joined us we had a great island dinner, followed by music provided by a steel drum band. We had more drinks and soon we were both taking turns dancing with you. As the evening wore on I found that Keith was holding you closer as you danced, close enough that I could see his thighs pressing against yours, I knew the rum was having its effect and I could feel the beginning of an erection.
It was exciting, seeing the desire in this stranger towards you and I felt a little tinge of arousal, and I knew you felt it too and would have a slight moistening between your thighs. We had been together long enough to know what we liked and tonight was no different. The effect of the rum drinks and this island was having an effect. I don't think this was lost on you either. When it was time to leave the bar I invited him back to the room for a night-cap (as if we hadn't had enough already and I could see from your look that you knew why I had invited him back at this time of night) He readily accepted and now the three of us were lounging around in our cottage enjoying another drink. I was leaning back in and arm chair, appearing sleepy, but still aware, and Keith was sitting beside you on our bed.
I stirred just enough to turn down the lights so I was almost in shadow, and you knew why I wanted the lights so dim, so I could watch this guy try and fuck you while I lay near you. Our friend took advantage of the lighting to place his arm around you, drawing you against him. You didn't resist, and I could see by your top that you were enjoying the attention. I had told you not to wear a bra under your tight top and your nipples were forcing their way through as I watched. I was wondering how far this was going and how brave he was going to be feeling my hard cock twitch in my trousers. It seemed to be going somewhere, as the next thing he turned towards you and kissed you full on the lips. No response from me as he looked over which gave him confidence, so the stranger kissed you again. You knew I was aware of what was happening, so why didn't I say something? Oh yes it turned me on to see you fucked that's why.
After another kiss he was confident that you were going to let him have his way with you so he swung you around so that you were lying flat on the bed with this stranger beside you, holding you in an embrace. You glanced towards me and knew I could see, even though I was in shadow, but still I kept quiet stroking my cock subtly under my trousers in the shadow and said nothing. You knew I wanted to see what you would do? Was I going to call a halt to this action? You were going to find out. When he began to unbutton your blouse you did nothing, and you did nothing when he pulled it free, exposing breast's which stood proudly with your hard nipples in front of him. You allowed another long kiss; you were flushed and breathing rapidly with this turn of events. You looked at me again-you could see my eyes but I couldn't see my expression and you could also see me rubbing my cock under my trousers.
You couldn't believe this scene that was unfolding, and you couldn't believe that I wasn't saying anything. We had talked about this and you knew I liked to see you used but it had never been like this before. Did I want this stranger to fuck you in front of me as I lay there pretending to be asleep? Everything about this island, this setting, the distance from home, and the drinks we had consumed lent itself to an erotic evening, and it seemed to be getting to all of us. The stranger was caressing your nipples with his finger-tips till they stiffened even more, and then he was using his mouth and tongue on my breasts, and I was becoming more and more aroused as I watched this from the shadow. You wondered if I had an erection-the stranger certainly did-You were very aware of the pressure against your leg. His fingers dipped down to your knees, sliding under your short summer skirt, slowly sliding up your thighs, pushing your skirt up. His hand was gently pushing your thighs apart, his hand now between them, stroking and caressing them, finally pressing against your panties, which I knew to be crotch less as I had chosen them for you that night.
You felt yourself moistening, becoming more aroused as his fingers slipped inside the leg of your panties, finding your moistness. You moaned softly when his finger moved in to you, pretending to be quiet so as not to wake me, knowing full well I was awake and enjoying every single thing. You murmured again when his finger found your clit. I watched him as he slipped off his trousers and underwear, and I thought now is the point you would either stop this or go all the way. I had unzipped my trousers now and had my hand inside wanking as I watched him and you. You wondered if I was going to say or do something, but when I didn't you knew that you were going to let him use you. You whispered to him, "Don't strip me." But he whispered back, "I've got to take these off," meaning your panties.
I was leaning forward trying to hear what you were whispering. Did I want you to go ahead? Did I want to see this stranger doing it to you? You could feel his very hard cock against your thigh, and you knew you were very close to doing it with this man-being penetrated by him.
You raised your hips to allow him to pull your skirt up under you, but you hesitated when he gripped the waist-band of your panties, attempting to take them off. You took a last look at my direction as I sat there stroking my cock now otherwise immobile. This scene was so far out, and you were so aroused that you lifted your hips, allowing him to slide your panties off, and now you're hot wet pussy was open to him. He pressed your legs and thighs apart further, lightly caressing your wet lips as he did so, pressing your legs open more as he moved between them, preparing to mount you. I gave a last look at you whose eyes were shining in the dim light, I was now pulling my chair closer to you making very little pretence of being asleep and he felt me move. He knew I was watching and was happy with the situation.
