After 2 days of nude fun, and giving and receiving handjobs from Cat and Antoine, P and I realized at least that much would continue happening for the rest of the trip. We met Cat and Antoine for an early lunch at a restaurant in the Lincoln Road shopping area. After lunch and a few drinks (there were always a few drinks when Cat and Antoine were with us!), we began walking around the shops, stepping into one from time to time. At one stage, Cat wanted to drink some water. I stepped into a coffee shop to pick up a bottle of drinking water. By the time I stepped out, I saw only Cat waiting there. I asked about P and Antoine - she pointed down the road, and I saw P walking with Antoine in the distance, with his arm around her waist. I started after them to catch up, when Cat smiled and pulled me back. She said that we should let them do their window shopping, while we did ours. I realized Cat and Antoine had struck again, making sure the two "couples" could be alone

.
I got over my uneasiness about P waltzing off with Antoine fairly soon, thanks to Cat and her flirting. It was nice to be alone with "my girl" in a non sexual setting, walking around hand in hand, kissing - I really enjoyed myself. As did P, on her jaunt with Antoine. She also got to discuss some business with Antoine, to ensure that an added bonus of all this was a boost at work.
We had decided to meet later in the day, to have sundowner drinks at Cat and Antoine's suite and then dinner. When we got there, Cat and Antoine were already nude, having got a head start in the hot tub, and P and I jumped in too

. Soon, as usual, the "couples" found some or other reason to be separate, with P and Antoine towards one end of the terrace, and Cat and I in the hot tub. She was teasing me, grabbing and gently stroking my cock, and kissing me too, but not going further. I suggested that now was a good time for a handjob, but she smiled and declined, and teased me for being so horny. She also said just handjobs would be boring. While they stood at the other end of the terrace, I could see Antoine holding and caressing P's ass - something I realized he had been doing a lot of, over the past few days. It still felt strange to see another guy squeezing P's ass (her ass has been squeezed by others when we've been married - though that was a very different situation, which I've detailed in another thread) while another woman stroked me.
A little later, while we were all refilling our glasses (so much alcohol!) Antoine told P he wanted to run through some work related documents that his office had sent through that afternoon. He had very conveniently set up his laptop on the desk in the bedroom, rather than the bigger study table in the living room of the suite

. I watched as my sweet, nude P strolled off into a bedroom with this charming Frenchman. However this meant that Cat and I had the run of the terrace, and could fool around on the day beds

. Cat had me on one of the loungers very soon (she was on top), and we were kissing rather passionately. She was kissing my neck, chest, nipples, and was gently tugging my cock every now and again, getting me really turned on. I also took the chance to kiss and suck on her boobs and nipples, something I'd wanted to go crazy doing from the moment I saw her boobs - Cat didn't have large boobs (a smaller B is my guess) - but they were awfully sexy.
While I'd lost track of my surroundings for a while, I suddenly remembered that our spouses were not far, and could surprise us at any time. Cat told me "Don't worry, what do you think Antoine took P into the bedroom for? Surely not only to look at a document?

. Come see". The bedroom also opened up onto the terrace - while the curtains were drawn, at one edge, there was an opening through which we could look into the bedroom quite discretely. I looked in with my heart pounding, and saw P standing slightly bent, over the desk, leaning and looking at the laptop screen, while Antoine was seated in the chair, and as was his habit, was caressing my wife's ass - except now in addition to feeling her ass, he was fingering her pussy, which was exposed from the back. It was quite surreal, seeing this guy putting his fingers into P's sweet pussy- a pussy which only I had touched that way sine we'd gotten together. She was obviously liking what he was doing. He then pulled her down, and had her sitting in his lap, as they continued "working"

. He then began fingering her from the front, and grabbing her boobs as well. They were also kissing sweetly. I suppose I was staring at the scene slack jawed!
I was brought back to my senses my Cat, who had moved herself a bit ahead of me, and was grinding her ass against my cock

. She has a fantastic toned ass, and it got me even harder than I was a few minutes earlier. We left those two lovebirds to their devices, and got busy ourselves. I went to work on fingering Cat, while kissing her and sucking on her boobs - her nipples were erect and quite large - big bullet like nipples on not too large boobs - quite sexy to me! I soon had more than one finger inside her, going quite deep. I was also massaging her clit with my thumb at the same time - and was quite proud to have her cumming quite hard, soon

. I expected her to jerk me off, but she seemed reluctant to do the same - she wanted to suck on my cock! Before I realized what she was up to, she had gone from kissing my chest, to kissing my balls, and the shaft of my cock. Wow! Felt great, and it was a great sight to have her mouth at my cock. She started licking up and down my shaft - I hated myself, but decided to stop her for the moment. I didn't want to do something P may not approve of. We decided to refill our glasses, and Cat called out to Antoine and P to ask if they needed refills too.
We all were out chatting, and on the pretext of taking a pee, went into the living room, signaling P to join me. I told her Cat wanted more to happen tonight, and I was very tempted - but didn't want to do anything without discussing with her first. P laughed and said the tag team continues to work in tandem - she said I assume "more" means oral sex? I was surprised - but she said that while fooling around, Sitting in Antoine's lap and kissing/fingering, he'd asked her to stand to better finger her. He'd also sucked on her breasts while doing this - I had mixed feelings hearing what my darling wife had been up to! P said that suddenly, Antoine went from sucking her boobs to kissing down her stomach, and started kissing and licking her pussy. She'd stopped him too, but admitted that it felt "electric" when his tongue was on her pussy. We both realized that this was happening, and said go ahead to each other!
Soon P and Antoine went back in to finalize their "document ", while Cat and I continued where we left off. Cat was obviously an expert cock sucker - her tongue had a life of its own! She could have probably had me cuming with just her tongue on the head of my cock

while my cock was a reasonable bit bigger than Antoine's, it is by no means anything more than average - at around 5.75 inches in length, and average girth (Cat said Antoine was a under 5 inches). As a result, it was easy for Cat to take all of me in that heavenly mouth. Her skills, and my pent up sexual energy (I'd been dreaming of a blowjob from her!) had me spurting a copious amount of semen quite soon - which Cat very admirably managed to take almost all of in her mouth. The image of her with my cum in her mouth, some of it streaking down to her chin is unforgettable. In a further surprise, she slurped and swallowed it

. I was literally in heaven. As we both calmed down, Cat dragged me to take a peak at what was happening in the room - we saw Antoine sprawled out like a king on the bed, with my darling P sucking on his cock. P is fairly skilled at sucking cock too, and Antoine was obviously getting the full benefit. P was able to take all of his cock into her mouth easily - quite a sight, seeing your wife with another man's cock in her mouth. I wanted to get back and eat Cat's pussy, but she wanted to watch. We saw Antoine cum - P isn't much of a swallower (she's occasionally swallowed mine, and she says no one else's). She allowed Antoine to cum in her mouth, but didn't swallow, spitting it out into a towel instead. I now had the sight of my wife with another man's cum in her mouth as well.
I dragged Cat back, as I was chomping at the bit to go down on her. For a woman in her 40's, she was in super shape (would have seemed mid 30's at most) and her pussy was looking great. I was a man possessed, as I worked on her clit, and got my tongue into her pussy - and had her cumming again. I've rarely enjoyed eating a woman out more. I kept going after she came, until she asked for a break. I teased her about keeping up with a younger guy - she warned me to watch myself, as she would otherwise expect an all night fucking

. I realized Cat enjoyed watching Antoine, as she dragged me back to the spy on the bedroom - to watch Antoine eating P's pussy. While I was not terribly interested in watching too long, I did have to admit that Antoine was skilled, and that P was in luck. I eventually dragged Cat back to continue eating that pussy, which I told her I wanted to take back home with me

. By now, I was hard again, and Cat obliged by sucking me again. Since I'd already cum once, I was able to last a lot longer, and really enjoy Cat's cock sucking skills. I finally came in her mouth, and this time she had no problem in getting it all and swallowing it all.
Soon after, P and Antoine appeared (I later learnt that they had to wait for some time in the living room while we finished

. We were all quiet buzzed, and rather tired, so decided to call it a night, and order food up to our respective rooms.
We discussed what had happened that evening once back in our room. Antoine, unlike me wasn't able to go for multiple rounds - this benefited P, as that meant Antoine spent a lot of time eating her pussy, and she did have a couple of orgasms. She did say he was very skilled, and it felt incredible when he was eating her, and from what I'd seen, i had to agree, and say that she was a very lucky girl - and that she may as well enjoy his skills some more. She teased me saying that she fully intended to do that

. She also joked about Antoine's penis size. I don't know how true, but Indians are apparently supposed to be on the smaller size in the cock department - all of P's other lovers have actually been smaller (to vetting degrees) than me. She joked that her luck had been balanced out by Antoine's cock being smaller, and in her mind, in such a scenario, she had imagined the guy she'd fool around with would be at least as big or bigger than me. I teased her and called her a size queen, and she teased me back saying I was relieved that Antoine was smaller. We both joked about how our oral sex skills probably didn't match up to Antoine or Cat, and we should actually take tips from them

. We then crashed for the night, wondering what the remaining part of our holiday would bring.
