My wife & I are off on holiday to the Seychelles and sitting in the departure lounge at the airport. I spot a gorgeous woman sitting all alone across the lounge - long dark hair, deep blue eyes, mediterranean skinned, fairly tall and smallish boobs. My wife spots me 'clocking her' so she asks me "do you think she's attractive?" and nodding in the direction of the woman. I have to give the stock, non-offensive answer to such questions "Well if I was single I'd be interested but I've got you sweetness, what makes you ask?". "you always seem be attracted to women that look nothing like me (Patsy Kensit, Kylie, Myleen Klass etc)" she replies. "Well that's because I've already got you so what's the point in fancying women that look like you?!" I cheekily mention to her, winking.

Our conversation slowly peters away as we board the plane and all thoughts about the long dark haired woman sink from my mind. I take the window seat as my wife usually falls asleep and I always want to look out of the window. We settle in as the long dark haired woman ends up taking the aisle seat in our row....my heart starts racing in excitement and I start thinking to myself "just don't say anything stupid, play it cool and don't make eye contact"....I mustn't upset the wife!

During the flight we exchange the usual polite travel chit-chat and, on landing at the airport, take a taxi to our hotel on the beach. We settle into our hotel, me getting turned on as my wife changed into her bikini so I took it off her, offering to put some suncream on her back. I massaged it into her shoulders as I sat astride her, naked.....this always gets me going & soon I'm hard so I move the "application of suncream" to her bum, with each rotation of my palms on her cheeks leading my thumbs more between her cheeks and just brushing her pussy lips. Eventually I can't hold back and we make love, resulting in a wonderful timed orgasm for us both.

With a rosy glow to our skin we get dressed into swim gear and head out to the beach....its early afternoon and hot. We both go for a swim in the crystal waters and settle onto our sun loungers to warm up again. As I settle into my book I notice that the long dark haired lady we sat next to is just getting to the beach too. "Oh look, there's the woman you sat next to on the plane darling" I point out to my wife. So we wave a polite hello as she settles onto a deck chair 30m or so away.

As the afternoon warms up, as usual, I'm getting bored with my book so take myself off for a run along the beach to explore. While I'm gone my wife feels the need, as she always does, to reapply sunscreen and, with me away, she has nobody to apply it to her back so she asks the dark haired woman to help her. As the woman applies it, she undoes her bikini top, rubbing the cream in more and more around the sides at the top of my wife's back, brushing the edges of my wife's tits. My wife dismisses this as the dark haired woman being thorough rather than anything sexual. She then works down to my wife's lower back and nudges her fingers under my wife's bikini bottoms, moving further and further down so slowly that my wife doesn't notice just how much of her bum is being massaged. Strangely my wife is starting to get a little aroused by this but, not being lesbian or bisexual, she tries to put the thought to the back of her mind just as the dark haired woman finishes rubbing in the last of the sunscreen.

The dark haired woman then asks that, as she's holidaying alone, would my wife mind returning the favour of applying sunscreen to her back. So they wander over to the dark haired woman's sunlounger and she lies face down so my wife can cover her back. She covers her shoulders and then works her way down the woman's back and, just as she's finishing the task off she thinks she hears a little groan of satisfaction from her. It was so quiet that it could have been her mind playing tricks on her so my wife thinks nothing more of it.

Over the next couple of days we get to know this woman, Fiona, better and she joins us on the beach as well as for the occasional meal. My wife seems to get hornier and hornier as the days pass and I just assume she's relaxing into the holiday more as we get to make love much more than we would at home.....first thing in the morning, in the shower and at night.

Whenever I'm away playing tennis or running etc Fiona and my wife apply suncream to each others' backs. Then one day after I'd left them on the beach to go for an early afternoon tennis game, I return to find the sunloungers empty apart from their towels. A quick scan of the sea and beach tells me they aren't there so I assume they've gone for a drink and I head back to our room for a shower.

Upon opening our bedroom door I take off my slightly sweaty tennis shirt to get ready for a quick shower. Once naked, I proceed to the bathroom and realised that I'd hung my towel on the balcony door by the bed. It was in getting this I realised I'd completely missed the scene in the bedroom and my jaw hit the floor with my eyes popping right out on stalks.

On the bed was my wife and Fiona, groaning and slowly lapping away at each other in a 69. A slightly surpressed "Ahem" gets their attention and Fiona and my wife disengage, looking like embarrased teenagers, their mouths and chins glistening in each others' juices. "Oh hi darling" my wife greets me. "Um Fiona and I, we just, um, kind of ended up getting it on - sorry darling!" as she then kissed Fiona.

I didn't know what to say. I'd always wanted to either watch my wife with another woman or have a 3sum with her and another woman and had fantasised about it for ages. But now I was in the moment I was stunned and speechless, caught in time. So all I could say was "Wow, you two look like you're having fun.....um, can I join you?". Both start to reply but my wife gains the upper hand stating "Well actually Fiona is lesbian so I don't think she'd like you to join us" as Fiona apologetically shook her head at me. My wife continued "I'm sorry darling, we just got chatting while you were away. I'd had a few cocktails and she asked me to put some suncream on her back. She then asked if I could do her boobs too as she didn't want to get her hands covered in cream. So I did and she got turned on and it turned me on and we kind of ended up in here, sorry".

"No worries" I replied, "Can I at least watch?". They both looked at each other and exchanged a cheeky glance before agreeing.

So the rest of the holiday was spent with my wife enjoying her newly discovered "bi side" with me sometimes watching and with the pair of us fucking like rabbits after Fiona had left.

It was wonderful to watch my wife go down on Fiona and taste Fiona's pussy as I kissed my wife after Fiona had left us to it.

The 3 of us even managed to get seats together on the night flight home. This time I was in the aisle seat so I could watch them kissing and fingering each other whilst trying to hide my erection from the air hosts & hostesses!
