Daisy was walking down the hallway from Coulson's office to the lab to see if Fitz had any updates on the project he was working on, when the Scottish scientist in question came rushing down the hall towards her. But before she could even open her mouth to say 'hi', Fitz grabbed her face with both hands and planted a quick, firm kiss on her lips.

"Thanks," he said sincerely after he pulled away, as he moved to continue on past her towards Coulson's office, where he'd been heading.

But Daisy spun around and grabbed his wrist before he could walk off.

"What the hell, Fitz?!" she exclaimed, staring at him in shock. "What was that?!"

Fitz looked at her in the same confusion she felt underneath the shock that was still winning out at the moment. "Simmons said– If I– While she was gone–" he stuttered out, his hands waving around vaguely as he spoke.

As Daisy just stared at his lack of an explanation with a look of confusion of her own, Fitz suddenly blushed brightly, and buried his face in his hands.

"She didn't tell you, did she?" he mumbled embarrassedly.

"Tell me what?" growled Daisy, wondering what the hell Simmons had told him, and clearly not her, that would lead to him walking up to her and planting his lips hard on hers. Not that she hadn't enjoyed it, brief though it was, but FitzSimmons were married, and while she'd never admit that she'd wondered what being with them would be like, they were together!

Pinching the bridge of his nose and opening one eye to look at her, Fitz said, "Since Simmons is going to be gone for a week on her mission, she said that if I ever really needed someone to kiss that I should kiss you. I had assumed she would have told you about it first, though."

Daisy stared at him in shock again for several seconds at this revelation, before her brain flashed back to a late night conversation she'd had with the biochemist several weeks prior when Fitz had been gone on an overnight mission.

~AoS~

"I just need someone to kiss!" exclaimed Simmons out of the blue.

She and Daisy were sitting on the break room couch together cuddling, everyone else having gone to bed a while earlier.

They lapsed back into silence for a while, before a half asleep and slightly buzzy from the several beers she'd had over the course of the evening Daisy mumbled as she leaned her head against Simmons' shoulder, "You know, if it was Fitz, I'd just say kiss me until you got back for him."

~AoS~

"Oh, shit," mumbled Daisy.

Fitz looked at her in confusion now.

Daisy sighed, pinching the bridge of her own nose. "Several weeks ago when I was half drunk, half asleep and Simmons and I were relaxing on the couch late that night you were off on a mission, she complained about wishing to have someone to kiss and I said if you ever needed someone to kiss while she was gone, that I volunteered." Daisy sighed again. "She apparently took me seriously, but never mentioned it again."

Now they were both blushing at each other, neither sure exactly what to say, until they both spoke at the same time.

"I'm sorry, I thought you knew."

"I guess you can do it again if you need to."

Fitz stared at her.

"You—? I can do it again?" he finally choked out.

Daisy shrugged. "Simmons is clearly okay with it if she told you to do it. And I can't say I've never wondered what being with you two would be like, though I'll kill you if you ever breathe a word of that to anyone. So if you're okay with it, then yeah — kiss me if you're missing your wife."

A week later, Simmons returned from her mission.

Fitz found her relaxing in the break room enjoying a cup of tea, after he finally got out of the lab after a late night. He walked up to her and kissed her gently, which quickly dissolved into something much more passionate as Simmons forced her tongue into his mouth.

"Ooh, strawberry," she purred as they broke apart several minutes later. "Looks like someone took me up on my suggestion — and even on the day I was coming back! Good as you imagined when she first joined the plane years ago?"

"After a really embarrassing first time where she didn't realize you'd volunteered her lips, we kind of got into a routine," replied Fitz slightly shyly, even though he knew she was the one who'd told him to do it, and so clearly wouldn't be mad at him. "And I only had a crush on her for a couple weeks, until you jumped out of the plane and nearly left me — I wasn't thinking about her long enough to imagine what she might kiss like!"

"Shame. I was hoping to find out if it was as good as your expectations, since I have been imagining what it would be like to kiss her," smirked Simmons in reply.

Fitz stared at her in shock. "You have?!"

"Yep. Why do you think I told you you could kiss her?" replied Simmons, taking Fitz's hand in hers. "If you've enjoyed the past week, and are okay with it, and Daisy is as well, I was hoping to bring her in more seriously and permanently. Or at least seeing if it could work." She looked at him for a second, before asking seriously, "So what do you say?"

~AoS~

Daisy was walking down the hall past the kitchen when she suddenly heard, "Hey lovebird! Get in here!"

So Simmons was back apparently, and thankfully didn't sound angry at her. Walking into the kitchen she found FitzSimmons holding hands and looking at her, seriously but not seemingly upset.

"Hi Simmons! How was your mission?" she asked totally not awkwardly.

"We were wondering if you'd like to sleep with us tonight," said Fitz, completely ignoring her poor attempt at small talk, before adding quickly, "And that doesn't have to be sleeping together sleeping together, it can just be sleeping in our bed with us."

"But if you want it to be the other kind, we're totally cool with that, too," added Simmons as soon as he stopped.

Not for the first time in the past week, Daisy found herself staring in shock at FitzSimmons, only this time they were both actually present.

"Excuse me?"

"We would like you to join us if you're okay with that kind of thing," said Simmons.

"And you don't have to jump straight into anything you aren't comfortable with. You can build up to anything more at your own pace," added Fitz, clearly intent on trying to keep as much pressure off of her as he could, while Simmons did the exact opposite, pushing for diving straight into the deep end — but she was pretty sure Fitz was comfortable with Jemma's route as well so long as she was.

"But if it's not quickly, I will pounce you and pin you to the bed or wall and snog you," clarified Simmons.

"No, she won't," said Fitz, shaking his head. "There's no pressure at all."

"But really I will, I've been wanting to kiss your pretty little lips for a while now," continued Simmons where Fitz left off. "So like Fitz said, there's no pressure, but I always get what I want."

"Okay, okay, I get the point," said Daisy with a chuckle, raising her hands in mock surrender. "And if you're really sure, then yeah, I'll sleep with you guys tonight — but nothing more than kissing for the moment."

"Deal," said Fitz, as both he and Simmons held out their hands for Daisy to take, before the three of them walked off towards FitzSimmons' room.
