"Jemma, when did we get a pet?"
"What, Fitz?" Simmons asked sleepily, trying to wake up. "We didn't get a pet. We live on an airplane — spaceship — time machine — big flying thingy you designed."
"Then why is there one curled up between our legs at the foot of our bed?" replied Fitz.
Simmons blinked her eyes and looked down at the foot of their bed, where sure enough, Captain Daisy 'Skye' Johnson, Inhuman extraordinaire and Acting Director of Shield when Coulson was out or kidnaped, lay curled up in an impossibly small ball on top of the covers between Simmons and Fitz's legs, looking like she'd been sleeping there for a while and was possibly still asleep, though Simmons knew that was most likely just pretend while FitzSimmons argued over her.
"Huh. I don't know," Simmons said, before adding admonishingly, "And don't call her a pet, Fitz."
"I like it," came the sleepy, mumbled voice of the younger girl, actually awake but just barely from the sounds of it.
"Daisy, you know I don't mind you being in our room, but — what are you doing here?" asked Simmons.
"Couldn't sleep. And at two in the morning, this seemed like a reasonable thing to do," their captain and best friend answered with a yawn, nuzzling her head slightly against Fitz's leg, much like a cat. "But I'm leaving now, so that you two can get the sexy times on before breakfast."
But instead of actually getting up and leaving like she said, she just rolled over onto her back and didn't move again, her bare stomach exposed a few inches where the hem of her already short sleep tank top rode up. So Fitz did the only reasonable thing in such a situation, and reached down and scratched her belly, causing Daisy to let out very cat-like mewls.
Looking over at his wife and giving her his very best Scottish puppy dog eyes, Fitz begged, "Can we keep her? Please…."
Simmons just rolled her eyes at her husband, before starting to scratch Daisy's side through the sheet with her foot and asking her, "Did you get your hands on some polyjuice potion and forget that you're not supposed to use it with cat hair?"
"No idea what you could possibly be talking about," Daisy replied innocently, before pretending to lick her paw with her tongue, causing both FitzSimmonses to laugh.
"Come here, kitty-Daisy," Fitz said, patting his chest and lying back down on his back.
Daisy immediately flipped over and scrambled the few feet up until she was lying on his chest, the top of her head tucked under his chin, where Fitz immediately began petting her hair. Simmons rolled her eyes at both of them again, but reached over and began stroking her fingers through the lower half of Daisy's long hair anyway, having always enjoyed playing with their teammate's hair, almost as much as playing with Fitz's short curls.
After a while, though, she asked mostly rhetorically, "Why exactly am I not bothered by a female that's not me lying on top of my husband — especially a beautiful, attractive, skimpily clothed one who is in our bed?"
Daisy sighed deeply, like it was a great responsibility that she carried around on her Inhuman shoulders, before answering gravely, "It's because you're madly, deeply, head-over-heels in love with me, Jemma — and I mean really, who could blame you, but you had a responsibility to Fitz as your first love to marry him."
Simmons burst out laughing.
"Ah, yes, I'm sure that's exactly it," she said, shaking her head at the younger woman. "You know, I'm beginning to think that I might be okay with it because of how absolutely hilarious you think you are."
"I am hilarious, Jemma, thank you very much," Daisy corrected, sticking her tongue out at the English biochemist.
"Actually, you really are," Simmons replied sincerely, moving her hand that had been in Daisy's hair up to lightly cup the younger girl's cheek. "And because of that, and of course the fact that I know I'm not the least bit threatened by you, if you really want to Daisy, yes Fitz, you can keep her as our ship pet and she can sleep in here, so long as she stays on your side of the bed, and your half of the room and dressers."
Fitz and Daisy immediately looked at each other, and Daisy shrugged as best as she could still lying on top of him.
So Fitz looked back over at his wife. "No problem. But is sleeping on my side of the bed curled up like a cat, or stretched out like a normal Inhuman?"
"Some cats sleep stretched out," Simmons answered.
Fitz turned back to Daisy. "There you go. You're officially my pet now."
"Purr," answered Daisy, pushing her head up against his chin like a real cat.
