FAQ: does anything intimate ever happen up there?

The answer is yes.

Between clients, with clients, with the crew, a mix of those - I've seen and experienced all of those.
There's something magical about being up in the air in an intimate situation like that. It feels more isolated than anything else - even more than in my own home. 

Maybe not the most intimate, but one of my most memorable experiences was flying between London to Cape Town. A bachelorette party of five Dutch women. They were already drunk when they got onto the plane, and thank God, not the annoying kind - they we're very sweet, and hilariously funny. It was just me and my colleague (guy) serving them. They we're eye balling my colleague constantly and whispering and giggling, what I assume were very dirty comments. He didn't mind, in fact he played along with it. He looked at me now and then and I could tell he was thinking about the big tip at the end of the trip. At one point I went for some refills and by the time back his shirt was off! He was still serving drinks, but just topless. He looked at me and gave me one of those shrugged shoulder looks, and showed some bills in his pocket. The girls were laughing so loud, the entire situation was just hilarious. Honestly though, I started feeling slightly turned on, not just because my colleague is very good looking. The entire potential that situation just carried was overwhelming me. It made my nipples hard and down there I got a tiny bit wet.
I carried on with my work and just laughed my way through it. At one point one of the ladies started shouting "Broek uit, broek uit!" which basically means "Pants off, pants off" in Dutch. He was teasing them, playing with them, saying "no, no, shirt only" etc. etc. They obviously weren't having it, and kept teasing him back. Me, in the mean time, I stood in the back and observed the situation. Even though it was a hilarious situation, my heart beat was racing and I got warmer and warmer. Again, what turned me on mostly, was the potential of how far that situation could go.
Until one of the girls got bored with his games and pointed at me and started shouting "rok uit, rok uit!" (meaning skirt off, skirt off).
By the way, it wasn't harassment at all (it might read like that now), but the entire situation was very chill in a way, everyone was at ease and I didn't feel uncomfortable at any given time.
So back to my rok uit situation. I suddenly became the centre of attention. I don't remember what was being said exactly, but the strategy they played was genius. They basically included me to do things, so my colleague would then do the same. Basically they wanted him all the way, and I was used as leverage. They also played it in a way that it was girls against boys (just one in this case). One of them walked up to me, put her cheek against mine, and whispered "is it okay if I take off your skirt?". My heart was pounding like I could just cum any second now. I replied softly "yes, take them off". She knew. Oh boy did she know how horny I was in that moment. She took it so slow. Her beautiful eyes kept gazing at mine as she went down on me as she slowly unbuttoned my skirt and pulled it down. I still had black pantyhose under it. Her hands, now being on the floor with my skirt slid back up along my legs where she gently held my butt. She stared at the my covered vagina, then looked up at me. We stared at each other. She stuck out her tongue slowly and started licking my pantyhose, right on the spot where my clitoris was getting wetter and wetter. She then used her teeth to pull down my pantyhose. A very sexy idea, but she had to use her hands in the end to pull them down all the way. That clumsiness and the small giggle we shared made it more intimate, like we were best friends just laughing about it. It made me feel very much at ease.
I wasn't wearing any underwear below those by the way, that made her smile as she started sticking her tong in my vagina as she firmly held my butt cheeks. I honestly don't know how long that all lasted and what the others were doing in the mean time, but it must've turned everyone on. I looked over and saw two of them standing next to my colleague kissing him in turns. (so apparently the other two managed to enter the cockpit and fuck the technical crew (the pilot and co-pilot).
As I was being licked I just stared at my colleague who was making out with two beautiful young women who at one point also went down to suck him. Now as some of you might know, I'm very sensitive for cinematic/theatrical moments, and this one felt so strongly like one. There was a perfect symmetry in how we were standing, at both ends of the plane, opposite of each other while we were both being licked and sucked. The moment made it even more magical when he started looking at me. We had never (me at least) thought about each other that way which is what made it even more special. One of the girls who was sucking him noticed he was staring at me and smiled. She went up and whispered something in his ear. He then walked over to me, fully naked with his hard erection pointing at me. I couldn't stop staring back at him. He stood next to me, while I was still being licked, and started unbuttoning my shirt. I took off my bra and now we were both completely naked. He laid one hand on my breast and moved his lips onto mine and started kissing me intensely. The lady that was licking me started sucking him now as well. She then held his dick and pushed it against my vagina. I startled and moaned at the same time. She did it again, she pulled his dick back and worth like she was jerking him off but at the same time wanting to penetrate me. She kept doing it and it made me wetter and wetter. I just wanted him inside of me so badly. He probably thought the same because he put his strong arm around my waist and pulled me in while he held his dick and pushed it right in there. I held my arm around his neck and through my head backwards while I moaned loudly. He started fucking me so hard there at the spot, still standing. I don't know if I have ever moaned so loudly. I think I came within a minute. I couldn't handle it, it was all too much - all in a good way. My orgasm was loud and shivering. I was sweating and trembling like crazy as I held him tight. "Broek uit, broek uit" one of the girls yelled again in the back, and we all had to laugh. He turned to them and I think he fucked all three of them while the other two were having fun in the cockpit. I watched for a bit, turned around at one point, picked up my clothes and went to freshen up and then cleaned up whatever mess was laying around. One of the best gigs ever.
