Skye was walking through the narrow corridor connecting the upstairs common area of the plane with the metal landing and spiral staircase down to the cargo hold and lab, that stretched the length of the Containment Cube on the other side of the interior wall, when Fitz passed by her going in the opposite direction.
They both squeezed to the sides so that they could pass in the narrow space without bumping into each other, only apparently they didn't squeeze far enough, as along with the normal brushing of arms and shoulders, Skye felt his hand accidentally brush across the fullest part of her boobs over her shirt. She didn't think anything of it in the moment, an innocent, unintentional brush against a part of her body that normally wasn't to be touched by others, nothing to get upset about or even more than surface acknowledge in her mind that it had even occurred. Some back corner of her mind did recognize that his hand shouldn't have normally been that high in the first place to accidentally touch her like that, but it wasn't a problem for her that he had unintentionally touched her tits, so she didn't give that niggling in the back of her mind even a passing thought. And she moved on with her day, continuing on down to the lab to talk with his wife, quickly forgetting that it had even happened.
Until two days later, when she was leaving the bathroom after a shower and he was entering after her, when it happened again.
It was even more noticeable to her this time because she was only wearing a cami (having forgotten to bring a bra with her amongst her other clean clothes to the bathroom), so his fingertips brushed straight over her thinly clothed nipples that were already stiffer than normal from the cool air of the bathroom after stepping out of the hot shower. But once again she assumed that it was unintentional, as it was a tight squeeze that they were trying to make at the same time since they were both too impatient to wait on the other to walk through before they did themselves, so it was really her fault as much as his, since Fitz wasn't the kind of guy to try to intentionally brush his hand against her clothed tits, especially when he already had a pair that he could just straight up grab and play with naked whenever he wanted to — his English biochemist wife's, of course. It was odd that it had happened twice in such a short period of time when it had never occurred before then, but they did live on a small plane and all rushed around too much, so things like this were bound to occasionally happen. And if it was to happen with anyone there, Fitz was certainly the man whom she would prefer it happening with.
But when it happened the third time, and they weren't in extremely close proximity as they passed by each other this time, she could no longer believe that it was purely accidental and unintentional, at least not this last time. And she couldn't help but question the first two times now as well, or at least the second one — the first time really could have been unintentional, and then he had deliberately done the second two since she had let him get by with the first time without calling him out on it. Because this time she was entering the lab through the glass sliding door as he was exiting, and he had to reach out a foot to be able to touch her boobs. His hands were already up at chest level since he was carrying a box full of electronic parts for whatever engineering reason that he was, and she was closer to him than strictly necessary since she was trying to cut the corner coming off of the stairs as much as possible without hitting him, but she had seen him coming so it wasn't like they nearly collided and he touched her then, and he had to fully let go of the cardboard box with his right hand and reach it out several inches with his hand fully extended in order for his fingertips to brush across her pert mounds as they did.
Sure this time that his touch was completely intentional, Skye still didn't say anything to him about it as she continued on into the lab and he headed up the stairs, but she did resolve to intentionally keep her body several feet away from his for the next few days at least, while she observed how he passed by his wife in close spaces, before she brought the matter up to anyone — Fitz or Simmons, of course, she wasn't going to go complain to AC or anything about it, she didn't have that big of a problem with it to get 'HR' involved.
And what Skye observed over the following week was that he did exactly the same thing with his wife every time that they passed in a narrow or even semi-narrow place without anyone else (besides her, at least) around, reaching his hand out and brushing it over her mounds, even more deliberately and lengthy than he ever had with Skye — touching from where the outside curve of Simmons' breast started, over her bust, till his fingers fell away again on the far curve of where her other breast flowed back into her far side.
And every time it happened Simmons seemed completely unfazed by it, like it was something that he had been doing for the entire ten years that they had known each other or at least for most of the time that they had been dating now into their marriage, something that she didn't mind in the least that he did with her even though it was semi-public — even if the back of Skye's mind was trying to tell her that the only 'public' times that he did it was when Skye was around, not when anyone else on the plane was around unless it was an extremely tight squeeze where no one except Skye purposefully looking for it would actually see it. And the longer Skye observed and the more times she saw Fitz brush his hand over his wife's clothed breasts, the more she began thinking that she had seen him do it before he had first done it to her, and it just hadn't registered in her mind that that was what he was doing since it wasn't to her whom he was doing it, and his significant other to whom he was doing it had never showed any signs of being bothered by it, or really even noticing it to begin with, though Skye was sure that the older girl did feel it, she just wasn't outwardly showing it.
So finally having collected all of the relevant data except for why he was doing it to her now as well instead of just to his wife, Skye prepared for how she was going to confront him about it the next time that he did do it to her, before resuming passing through tight places with him for the first time in a week, wondering how long it would take him to touch her again.
She didn't have to wait long at all, as the very first time that they passed closely by each other again — in this case in the corridors out the back side of the lab near where Fitz had set up the prank on her that had scared him more than it had her — he did it again, extending his hand just enough to let his fingertips brush lightly over her shirt across the fullest part of her tits. Only this time she was ready for him, and grabbed his wrist lightly but securely when his hand was crossing over the bridge between her breasts, causing him to naturally spin and face her as he couldn't keep walking past her when she had his wrist grasped in her hand.
"Fitz, what are you doing? I'm not your wife," she asked in a more curious tone than anything else before he could speak, wanting an explanation not an apology from him.
"Slow progression," Fitz answered without a hint of embarrassment at being 'caught' inappropriately touching her. "Light accidental touches here and there in tight places, leading to firmer touches that aren't so easily explained away as being unintentional, until finally deliberate touches and even full grabs that are clearly being done on purpose. But because you didn't say anything when they started and were just light touches, you continue to let them slide when they start to seem less likely to be accidents, until finally by the time it becomes obvious that I'm deliberately touching your boobs every time we pass by close enough that I can without making a scene that anyone else would see, you still let me do it and just ask why at some point. Only you clearly cottoned on a lot quicker than Jemma thought you would. I know you've been keeping at least two feet away from me every time we've passed this past week, after the first three times I touched your boobs."
"Okay, but why? And your wife's a part of you touching me the same way you touch her?" Skye asked back, only more confused than before by his answer, just in new ways, since she understood the concept of a slow build where if she didn't say anything when it was small, she still wouldn't say anything when it was big.
"Oh, believe me, I am not touching you in all the same ways I touch her," Fitz smirked back lecherously, doing things to Skye's lower belly that she would never admit, out loud or to herself. "And of course she's part of it, she's the reason I'm doing it — you really think I'd do anything like that that she doesn't approve of? I'm not going to touch another woman's tits or between her legs, clothed though they may both be, without her being okay with it."
"You've only touched my boobs through my shirt, you've never tried brushing your hand over the front of my jeans or shorts, but that still doesn't explain why you're doing what you are, or why Jemma wants you to," Skye said.
"I brush my hand over the front of your pants or shorts and you might very well slap me, or at least slap my hand away. But your chest — that you're much more likely to let slide at least a few times if you think it's unintentional," Fitz explained. "But as for the why — Jemma thinks you could benefit from having someone touch you, but knows you'd balk if she just walked up to you and asked if you'd like me to relieve your touch-deprived state, no matter how touch starved you in fact are. Whereas if I slowly work you up from little touches to bigger ones, you'll have already accepted a lot of what you need to before the question comes up, so it'll be easier to convince you to accept the rest — only you asked the question far earlier than you were supposed to, which makes my job that much more difficult since it wouldn't be polite of me to shove you up against the wall right here and now and slip my hands under your shirt to palm your breasts directly over whatever bra you're wearing right now, while bringing my knee up between your legs to give you friction down there, and try and make you hump my thigh while I play with your tits."
"Um, no — you can't do that," Skye replied, even while her slit wettened slightly at the thought of him actually doing it, and her mind unhelpfully supplied the fact that it was very unlikely that anyone besides possibly the biochemist herself would walk up on them where they were in the belly of the plane. Then she straight up lied, "And I'm not touch-starved, Jemma's being ridiculous."
Fitz immediately reached his hand up and gently cupped the side of her face, rubbing his thumb lightly over her cheek. Skye instinctively leaned into his touch and let out a small mewl of contentment.
"Uh-huh — not touch starved at all," he replied dryly.
Skye narrowed her eyes and glared at him, but didn't move away from his hand in the least bit as she said, "I am not. Your hand just happens to feel good, that's all."
"It'd feel even better on your boobs," Fitz returned completely unashamedly. "And no one ever said you actually had to be touch-starved to accept what Jemma and I are offering you, that's just the reason she thought I should try seducing you in the first place. You can be completely touch-saturated from all the zero people on or off this plane touching you right now, and still accept my touch — just, you know, because more touch is always nice, and you just said my hand feels good."
"I'm not going to say yes, because that's just ridiculous, but purely out of curiosity, when you say accept your offer of touch, are you talking about brushing against my boobs every time we pass, like you do with Jemma?"
"I would, unless you told me not to, but it could be a lot more than just that, too," Fitz answered. "How far really is up to you, we're not trying to force ourselves on you, but as wide as the making out and canoodling spectrum is, is how large of a range you have to work with. Small brushes and touches not only when we pass by each other but also any time we're sitting or standing around not engaged in work and no one else besides Jemma is around, all the way up to full-blown sex and dating. I mean, I'm going to nudge towards the dating part eventually no matter how much Jemma insists it can just be physical, because I'm the romantic of the two of us, but to start and while you figure out what you want and are comfortable with, it's just how you tell us we can touch you — or just me, if you're uncomfortable with a fellow female touching you. And you're of course welcome to touch either of us however you like, or not, you don't have to ask permission on that. But this can strictly remain in the common areas of the plane, or it can also be in any of our bunks, where it can safely be more intimate — or only in the bunks in private, even if it's just this light, if you don't want it at all in public even when no one else is around to see it. It really is completely up to you what you want out of this. So what do you want?"
"My best friends not to be completely crazy?" Skye replied weakly. "And you said Jemma would do this too, not just let you play with me?"
"That's up to you, of course, and her touching certainly doesn't have to be to the same magnitude as mine — or hers could be more than mine, if you preferred — but she's more than happy to do whatever you want her to. She's completely normal like me, and I'm pretty sure you — I've never heard any wild tales from you in that direction, at least — but she'll try things for and with you that she normally wouldn't."
Skye ho-hummed around for several seconds, shifting her weight between her feet to try and ignore the ache building between her legs, her mind reliving the sparks that his brush of her clothed boobs had sent through her body all four times and how much she had instantly missed his touch when he had finally dropped his hand from her cheek a minute before as he had explained all of her options for what she could have — yeah, she was down bad. She had no clue how this would all play out in the end, dating a married couple seemed completely absurd to her, and where did they even have in their minds that dating her could eventually go, but she couldn't help but want to get what she could while she could, as she really was far more touch-deprived than she had realized if her body's reactions were anything to go on.
So she straightened back up tall and said, "Okay. I don't know what I want, and we're both halfway supposed to be doing work things at the moment, but you can continue brushing my tits when we pass by each other, and we'll get to someone's bunk later today with Jemma to see what more feels right."
