A/N: Merry early Christmas, all my dear readers! Hope you all have a wonderful one!

Five mornings in a row as she casually sipped her tea aboard the BUS, Simmons watched Fitz and Skye literally crash into each other as they rushed around to get ready in the morning.

And every time it was right at the door of Skye's bunk as Fitz hurried back to his own bunk from showering and Skye stepped out of her bunk to head to the shower herself, just like clockwork — Simmons was pretty sure that she could set her watch by it had she any need to. Not that she was at all bothered by the two of them making such physical contact every morning, seeing no evidence that either of them were going to hit the other hard enough or in the right location to cause any brain damage or other injury — no, it was merely an observation that she had been making all week. But it had got her thinking the previous afternoon while she was waiting on some of her experiments to do their thing, and it was nearly Christmas.

So this morning after Fitz had disappeared into the bathroom to take his shower and before Skye's alarm had even gone off yet to rudely startle the soundly sleeping girl awake, as Simmons waited on her kettle of water to boil for her (and later Fitz's) tea, she ingeniously enacted her carefully concocted scheme.

And sure enough, ten minutes later as she sat at the little table sipping her tea and eating halfway stale store-bought scones (living on a plane did have its downsides), there came Fitz hurrying out of the bathroom as the door to Skye's bunk began to slide open. And perfectly continuing a now six day streak, the two of them collided and only stayed upright because they both grabbed the other around the back or waist, practically smushing their fronts together in the process.

Only this time before they could seperate and begin apologizing to the other (but heaven forbid actually start taking their time to make sure that they didn't run into the other to begin with), Simmons cleared her throat to draw their attention to her, as she pointed above their heads.

They looked up simultaneously to see the mistletoe that she had hung there, before looking back down at each other. And before Fitz could react, Skye grabbed his face in her hands and smushed her lips against his, kissing him passionately. It took Fitz a second longer to respond, but since it had been his wife to point out the mistletoe that they were standing beneath, and he had a strong suspicion that she had been the one to put it there in the first place — Skye could be bold for sure, but her flirting with him had never been that blatant before — he trusted that his wife wanted him to snog their best friend and so started snogging her back.

When they pulled back a minute later, both out of breath, Fitz immediately looked over at Simmons. Who was smiling back at him softly with love clear in her sparkling eyes, having clearly been watching them the whole time, increasing his suspicion that she had set all of this up, though he still had no clue why.

As Fitz was still holding her tightly to him, Skye looked over at Simmons as well, immediately being struck by the look of pure love that Jemma was giving Fitz — damn, if the English woman was that head over heels for the Scottish engineer, why on earth had she just had them kiss? Because Fitz clearly wasn't the one who had put up the mistletoe, and she hadn't done it herself (not that she hadn't ever considered the idea), which only left the biochemist who had pointed it out in the first place.

Unable to help herself, she broke FitzSimmons' moment by asking Simmons, "Would you like to use the mistletoe yourself?"

Simmons broke her gaze with her husband to look at Skye with a piercing look that Skye couldn't decipher, before answering pleasantly, "I'm surprised you would offer, but of course."

Skye felt that there was something wrong with the way that Simmons had answered her, but pushed it out of her mind as she went to extract herself from Fitz's comfortable hold of her, so that Simmons could take her place. Just to have Fitz continue to hold her as tightly as before not letting her go, as Simmons stood up and started walking over to them. Skye instinctually tried for a second or two longer to extract herself by her own means, and by the time her brain accepted that she couldn't without full-out shoving Fitz away from her so she started to open her mouth to say something to Fitz about letting her go, he suddenly let her go on his own.

But before she had time to move away from him for Simmons to take her place, Fitz stepped to the side and Simmons took his place, resting her hands on Skye's upper arms, looking the younger woman straight in the eyes. And suddenly it clicked in Skye's mind why Simmons' answer had seemed off — instead of using the mistletoe herself so that she could kiss Fitz whom she had been making heart-eyes at, Simmons had apparently thought that Skye meant use the mistletoe to kiss Skye. Hence the 'surprised you would offer' comment.

"I meant to kiss Fitz!" Skye cried out. "Not me!"

"Why? I can kiss my husband whenever I like, I don't need mistletoe as a pretense to do that," Simmons answered, not moving an inch.

Skye stared at Simmons in shock, her mouth dropping open slightly. It took a few seconds, but she finally managed to gasp out, "Husband?!"

Simmons nodded in the affirmative, as if Skye had simply been commenting that the sky outside of the plane window was blue.

"But you just let me kiss him! You pointed out the mistletoe we were under that I thought you put up there!" Skye shouted back, unable to help herself.

"Of course I put it up there," Simmons answered calmly, knowing that her husband wanted the answer to this as well and figuring it best to go ahead and get it out of the way, especially since it was unlikely that Skye would now let her kiss her without the full explanation. "I've watched you two run into each other in that exact same spot for the past five mornings in a row not including this one, so it was as certain of a bet as could be made that you would this morning as well. So after Fitz left my bunk to go shower and before your alarm went off waking you, while I was waiting on the water for our teas to boil, I attached the mistletoe to the plane ceiling so that when you crashed together yet again this morning, I could point it out and finally relieve some of the unresolved sexual tension between you. Didn't really expect to get an opportunity to kiss you myself, but certainly wasn't going to pass up the opportunity when it did occur, and Fitz can read my mind enough to know what I wanted."

"But — Why?! And Fitz and I don't have any UST, he's married to you! — apparently."

Simmons rolled her eyes at the younger woman. "You can't say that you and Fitz didn't have unresolved sexual tension because he's already married to me, when you didn't even know that he was married to me to begin with. And you two have absolutely had sexual tension since the moment you joined us here on the BUS, Skye, which has obviously been unresolved until just a minute ago. But as for why I took advantage of neither of you paying any attention in the mornings to address the issue, that's really quite simple — I want you for at least my husband, if not myself as well depending on your interest."

"What she means is, she wants you as our girlfriend," Fitz interjected as clarification for the younger woman, 99% positive that's what his wife was saying.

"Yes, of course — isn't that what I said?" Simmons responded.

"There were multiple things that could have meant, none of which made any more sense than the others," Skye retorted, as girlfriend of a married couple made no more sense than one time Christmas present in bed for Fitz. "You're crazy, Jemma!"

"Is that a no?" Simmons asked back pointedly. "I know you've eyed up my husband before, before you knew that he was already taken."

Skye instinctively glanced over at Fitz before returning to looking at Simmons, chewing her lower lip for a few seconds as she thought. Then without warning (and before her mind could stop her), she plunged forward and smothered Simmons' lips with her own, kissing her even harder than she had Fitz a couple minutes before, as much to ignore and make shut up the screaming in her own mind telling her that she was out of her mind.

Simmons had no hesitation in snogging back with abandon, tasting the American girl for the first time. But she did pull back on her own after half a minute instead of waiting until the need for oxygen forced them apart, wanting to iron down the details as they did all have work that they were supposed to be getting ready for instead of round robin snogging.

"Does this mean you are agreeable to becoming our girlfriend and dating us?" she asked.

Skye shrugged kind of helplessly. "I don't even know what that would actually mean, what with there being two of you together and us living on a plane, but sure — why the hell not? It could be fun, and certainly a hell of a lot more action than I'd get otherwise anytime soon."

"Great!" Simmons said brightly, before looking over at her husband and smirking, "Merry Christmas, Fitzy — and of course you, too, Skye, and myself."
