From theclaravoyant: "Fight me" and/or "join me." Requested from a fanfiction meme on tumblr.

"Fight Me": I will write a drabble out my character fighting with/or against yours.
"Join Me": I'll write a drabble about my character giving your character an offer [be it a proposal for an alliance, asking them to join them in an activity (you can get dirty if you want), feel free to specify.]

This was sent to me a while ago, but I always fulfill my promises! Combined both of them like I usually attempt to do when I get double requests. Enjoy! (rated T for sexual innuendo near the end)

"So, May has been teaching you how to punch?"

Startled by the voice at the doorway, Jemma jolted out of her workout trance, but her eyes stayed fixated on the punching bag in front of her. "Just want to defend myself in case Hive attacks again."

Fitz sighed from his place against the door frame. "You know that's not going to be enough, right? If three slugs to the chest didn't deter him, I doubt a broken jaw or nose will, either."

"Well, since we haven't found a solution for the blasted parasites he uses to control Ward's body and other Inhumans, this may be my only way to escape," she bit back, gritting her teeth as she felt the rebound of the punches radiating through her sore knuckles.

She saw Fitz throw his hands up in defeat in the reflection of the mirror. "Okay, you have a point."

Jemma grunted in response, throwing another pathetic punch at the bag. She wasn't improving a lot, as she had never been the athletic type and that certainly wasn't to change with the sparse time pushed aside for sparring lessons in between missions, but if Daisy could vibrate an attacker to death and May could knock out a guy with a swift kick to the head, then she sure as hell could find some way to contribute to the team besides locking herself up in the lab trying to find a cure for the effects of Hive's "sway."

"You could've told me," Fitz commented, strolling over to pick up a pair of gloves from the corner of the room. "May's been teaching me, too. Since we're low on field agents and Hive is building his 'army'…" The snap of velcro reverberated through the air as he fastened a glove to his wrist. "Coulson needs all the help he can get."

Wiping a hand over her damp brow, Jemma snorted. "I'm not going to fight you, Fitz."

"What, you're scared I'm going to beat you?" he snickered, tossing a chest plate her way. "Because I thought Jemma Simmons excelled at everything."

She rolled her eyes when Fitz wasn't looking. She should've seen this coming. By now, Fitz knew how to push all of her buttons, and her competitive one just happened to be sensitive to the slightest touch. "Is that a challenge?"

The corner of Fitz's mouth perked up. "It might be."

"Good. Because you're still the pasty kid with the red inhaler attached to his mouth whenever we had to run a mile in my mind."

"I grew out of that, thank you very much!" Fitz countered, dodging a punch to the face from Jemma and aiming for her stomach, which she caught with the palm of her hand. "And this is coming from the agent-" he ducked down as a leg swiped the curls on his head "-that couldn't even fall down on command!"

"Well you're the one who didn't come in at the heels of Doug!" She let out a startled squeak as Fitz caught her elbow from behind, realizing too late that his face was ridiculously close to her own. "You…messed me up."

The words faded in her mouth and she bit her lip as the scent of sweat and cologne intermingled around her. Her pause was telling, a wrinkle in her cloak of determination, and Fitz took advantage of her blunder. "Why Simmons, are you distracted?" Though the vibration of his tsks danced wildly in her ear, fueling further the adrenaline rush running through her body, the pheromones and teasing did not wipe May's lessons from her mind. "A good fighter must always maintain-"

With a swift kick to the ankle and the thrust of her trapped elbow, Fitz fell to the ground. He groaned and wheezed, hand clutching his rib cage, as Jemma tumbled promptly on top of him. "You know…" She smiled slyly, licking her lips as she looked down at him. "I'm tired of fighting. I can think of…much more pleasant things to do in this particular position."

She dragged a nail down Fitz's collarbone, relishing in his apparent shock as she allowed her nail to snag on his collarbone. "Can we, er…" He gulped audibly. "Could we go engage in those activities? Now?"

"Only if you admit that I kicked your ass."

Fitz grunted. "May taught you well, I'll admit that." He wiggled himself out of her grasp. "But this isn't over."

"We can spar together more often?" Jemma suggested.

Fitz chuckled, grabbing her hand, and they both stumbled as they helped each other up. "If all of them end like that…" He grinned at her, gesturing to the floor. "I wouldn't be opposed to it."

From that point on, Jemma proceeded with her tendency of being on the top– literally and figuratively.

Okay, I officially love writing sassy FitzSimmons. And I was originally going to include cockblocking shipper!Daisy at the end, but the drabble didn't work out that way, unfortunately. And the fight scene was super short because I'm not very good at writing those in length :P
