Arianna huffed as she lifted the weight bar up for the last time, her back straight and legs apart as she lowered her arms slowly and carefully to finally set the weights back down. She'd been working on weights for the past hour, and it was definitely starting to become exhausting. She wiped her sweaty forehead as she unstrapped her other hand from the bar before turning to fetch her water bottle from beside her workout bag.

As she did, her eyes were drawn to her boyfriend, who was currently punching a heavy punching bag in the middle of the boxing ring Tony had placed in Steve's gym. It was custom-made (by the billionaire himself) for the super-soldier and so Steve didn't have to worry about it breaking every other day. It now only broke every month.

Arianna leaned against the pillar she'd set her bag against, grabbing her water bottle before she observed Steve's workout. His posture was good, as expected of a seasoned fighter- back straight and his feet shoulder-width apart with his left foot forward as he punched with his dominant right arm, although Arianna had often told him he needed to be lighter on his feet. He was too grounded on them, which made it a potential weak spot.

He was currently focused on the curve of his arm as he punched the bag, making sure to keep his form correct so as not to injure himself. Arianna ran her eyes over him as she took her break, roaming down from the top of his golden head, his sweat-soaked back and towards his-

"Like what you see?"

She grinned as she lifted her eyes back up to see Steve hiding a grin as he carried on punching, keeping his eyes focused on his fist.

"Was I that obvious?" Arianna laughed as she walked over while Steve gave the bag a final punch. He then hit the button on the top, and the bag was pulled up and away to be stored with the spares while Steve turned, grinning as Arianna slipped into the ring beside him.

"Just a lot." He teased as he took the water bottle Arianna offered with a nod of thanks. "I only thought your stare was going to burn a hole in the back of my shirt."

"Mm, then you're not as observant as I gave you credit for." Arianna teased back. "Because I was definitely not focusing on your back."

"I was trying to keep it polite." Steve shrugged, fighting back a smile as he tried to keep a neutral expression.

"Is that right?" Arianna joked, and he hummed.

"So?" He asked, and Arianna raised a brow as she asked back: "What?"

"Like what you saw?" He asked, his eyes sparkling with humour even as he tried to keep a straight face.

Arianna laughed, before she teased: "Hm, I don't know… I think I've seen better."

"I agree." Steve replied easily, making Arianna lift a brow.

She then went a little red in embarrassment as Steve leaned in and whispered in her ear: "Your butt is definitely cuter."

"Shut up." Arianna laughed as she swatted him, and Steve dodged the blow before grabbing her hand. She reacted quickly, turning around swiftly to lock her leg around him before spinning them over so that she had landed on her feet in the middle of the ring while Steve landed in a crouch thanks to his quick thinking.

"Dang, it would be fun if you'd landed on your back just once." Arianna joked as Steve straightened up, and he chuckled.

"It would be more fun if you'd stop trying to sneak an attack on me." Steve countered, although his eyes were sparkling with amusement.

"Keeping you on your toes, old man." Arianna teased.

Steve raised a brow, before his eyes narrowed playfully. He suddenly shot forward, grabbing Arianna and pinning her on her back on the ring floor before she could react. He was careful to avoid knocking her hard, using his arm to prevent her head from bashing into the floor while Arianna in turn reacted quickly enough to shift her weight so that she landed on the ground with the least amount of impact, although Steve's firm hold on her already protected her from any injury.

Her brow still arched in surprise as she looked up at Steve in a mixture of curiosity and amusement as he leant down over her, using his weight on her torso to keep her down.

"Mm, you should be ashamed of yourself for being beaten by an 'old man'." Steve teased and she laughed at him.

"Well," she answered as she shifted slightly, "I don't know…"

Steve raised a brow as she curled a leg around his waist suggestively, only to blink in surprise as she suddenly whipped them around, shoving him to the ground below her as she straddled him, pinning him to the floor.

"Don't count your chickens before they hatch." She laughed as she leant down, keeping him pinned below her.

"I win." Arianna announced in a childish manner that would have made Clint proud.

Steve laughed with her, shaking his head in defeat. She smiled too, before leaning down to kiss him and she chuckled when he wrapped his arms around her and pulled her closer as he deepened the kiss.

"Steve…" Arianna murmured as his hands began to wander down her side.

"Hmm?" He hummed nonchalantly as she pulled back slightly and he kissed her neck instead.

"What happened to training?" She pointed out and he shrugged.

"I think I've found something better to do today." He answered lightly and she raised a brow as he pulled her hips against his in a way that left no doubt as to what he was thinking about.

"Seriously?" She deadpanned although it was slightly ruined by the breathless tone as Steve kissed her neck again. "You know, Clint'll kill me if I skip another workout."

"You've already finished your circuit anyway." He retorted.

"And besides," Steve kissed her softly, "I'd never let anything hurt you, babe."

Arianna laughed, shaking her head as she answered with her eyes shining with amusement: "You can't try and be corny romantic when you've got me like this."

She grabbed his hands, lifting them back up to her back and off her ass, and he laughed with her as he shrugged.

"Hey," he replied casually, "like I said- you've got a cute butt. What can I say?"

"Ooh, watch it Captain." Arianna teased. "Or else I'll have to report you for sexual harassment against your subordinate officer."

"It wasn't sexual harassment against my subordinate." Steve returned. "It was an compliment towards my girlfriend."

"Oh, really?" Arianna chuckled, and he answered with a mischievous wink: "Yes, really."

"Hm, so it wasn't," Arianna leant down to brush her lips against his flirtatiously, "a sexual reference in any way?"

"Well," he answered slowly as he brought a hand up to her neck to keep her down so he could retaliate in the same manner, "if my beautiful girlfriend took it that way, I certainly wouldn't argue."

Arianna chuckled before she was abruptly cut off by Steve's lips as he finally leant up and kissed her. She answered his kiss enthusiastically, deepening it quickly as he slowly sat up, keeping her straddled on his lap as he did.

"Steve." Arianna breathed when they finally broke apart for air. "I really do need to work out or Clint will kill me… and probably you."

"I think I can think of a 'work out'." Steve answered as he ran one hand up and down her thigh while the other ran down the back of her neck, to her back and down.

Arianna groaned, reaching back and pulling his hand back up before it could reach her butt as she warned: "Steve."

"Ria." He answered, and she rolled her eyes although she grinned when he kissed her nose.

"Come on, Captain." She sighed. "I really do need to finish another circuit."

"I'll help you." Steve sighed as Arianna pulled away reluctantly and got to her feet. "I'm done with my training for the day."

"No you aren't." Arianna teased lightly as she glanced back at him flirtatiously. "You've still got to train with me."

He froze slightly before he groaned.

"Ria, if you want to get that circuit done, don't tease me like that." He warned as she laughed back at him.

"Sure thing, Cap." Arianna laughed. "Although why you're getting all hot and bothered is completely beyond me."

Steve snorted before a mischievous gleam entered his eyes. He walked over as Arianna was getting ready to start her circuit, grabbing her waist and startling her. She blinked and shot him a confused look before it became ashen as Steve grinned: "What? I'm just helping you keep your form."

"Steve." Arianna warned, but he simply turned her around, taking her hands and wrapping them around the weight bar correctly. Arianna shifted slightly as the move made Steve lean right against her back, the warmth coming from his chest radiating onto the back of her tank.

"Yes, babe?" Steve asked in an overly casual tone, a wide smile on his face as he got revenge on her for teasing him.

"Steve…" Arianna warned as she tried to focus back on the workout, when Steve removed his hands, brushing his fingers casually against her arms as he straightened up.

"That is my name. What is it?" Steve asked, feigning innocence as Arianna shot him a murderous look.

This is definitely sexual harassment. Arianna thought as she ground her teeth in irritation. And I hate him for it… as much as I love him for it.

"You're not focusing." Steve chided as he grasped her hips and corrected her stance.

Her momentary daydream had caused her to shift unconsciously, the weights tipping slightly more to her dominant right rather than staying evenly balanced. She exhaled sharply at the contact, before Arianna dropped the weights abruptly back down.

Steve blinked, startled, as she spun around, and he just caught sight of her hazel eyes blazing in frustration before she'd slammed her lips onto his. Steve staggered back slightly from the sudden movement before he wrapped his arms around her and hoisted her up. Arianna wrapped her legs around his waist as she deepened the kiss, her hands tangling in his short blond hair as he kept one hand under her thigh for support while the other sat on the small of her back.

"What happened to the circuit?" Steve breathed when they finally broke apart for air, although they kept their faces close together.

"Shut up, and carry me to the bedroom." Arianna replied and he grinned.

"Yes, ma'am."

His lips captured hers once more as he carried her quickly out and down the hallway to their bedroom. Just before they left thought, a small thought passed briefly through Arianna's mind: 'Clint is so going to kill me tomorrow.'
