The training room at the Avengers Compound hummed with the electric buzz of high-tech machinery and the rhythmic thud of impact. Diego Cruz, an 18-year-old mutant with a penchant for comic books and a vibranium-adamantium-titanium arm, stood at the center of the chaos. His muscular frame, marred by jagged scars from past experiments at the hands of the Friends of Humanity, glistened with sweat under the harsh fluorescent lights. His short black curly hair bounced with each powerful throw as he hurled a gleaming Captain America shield at a swarm of holographic enemies. The simulation was relentless, but so was he—every toss of the shield sliced through the air with a precision that belied his nerdy exterior.
“Take that, you pixelated punks!” Diego muttered under his breath, a grin tugging at his lips as the shield ricocheted off three targets before returning to his metallic grip. For a virgin who’d spent more time debugging code than flirting, he was damn good at this.
The simulation beeped to a halt, the holographic foes dissolving into thin air. Diego let out a shaky breath, wiping his brow with the back of his flesh-and-blood hand. The shield felt heavier now, a reminder of the legacy he was trying to live up to. He was just about to sling it over his shoulder when the training room doors slid open with a hiss.
“Well, well, if it isn’t my favorite rookie,” came a voice, smooth as polished steel and twice as sharp. Captain Marvel—Carol Danvers—strode in, her signature red-and-blue suit hugging every curve of her powerful frame. Her short blonde hair was tousled just enough to look effortlessly sexy, and her smirk could’ve powered the entire compound. She was one of Diego’s adoptive moms, a human powerhouse who’d taken him under her wing after his rescue from the anti-mutant labs. But right now, she didn’t look like a mom. She looked like trouble.
Diego straightened up, his heart doing a little flip. “Hey, Carol. Just, uh, breaking in the new gear. You know, standard nerd stuff.”
She crossed her arms, leaning against a nearby console, her eyes raking over him with an intensity that made his skin prickle. “Standard nerd stuff, huh? You’re throwing that shield like you’ve been at it for years, kid. I’m impressed. And trust me, I don’t impress easy.”
He chuckled nervously, scratching the back of his neck with his metal arm, the faint whir of its servos filling the awkward silence. “Thanks. I’ve had a good teacher. Or, y’know, a scary one.”
Carol laughed, a low, throaty sound that sent a shiver down his spine. “Damn right, I’m scary. Gotta keep you on your toes.” She pushed off the console and sauntered over to where the shield rested against a wall, bending down to inspect it. Her position gave him an eyeful of her toned backside, and Diego’s teenage brain short-circuited.
Before he could stop himself, emboldened by a mix of adrenaline and sheer stupidity, his flesh hand shot out and gave her a playful smack on the butt. The sound echoed in the cavernous room, and Carol let out a surprised yelp, spinning around with a look that was equal parts shock and amusement.
“Diego Cruz, did you just smack my ass?” she asked, one eyebrow arched so high it could’ve touched the ceiling. Her tone was dangerous, but there was a glint in her eye that told him he wasn’t in real trouble. Not yet.
He froze, his bravado crumbling like a house of cards. “I, uh, I thought it’d be funny? Like, a bro thing? I’m sorry, I’m an idiot, I—”
“Relax, kid,” she interrupted, straightening up and stepping closer, her presence overwhelming. She was taller than him by a few inches, and the way she loomed made his pulse race. “I’m not mad. Surprised, sure. But not mad. You’ve got guts, I’ll give you that. Question is, do you have the follow-through?”
Diego blinked, his mouth dry. “Follow-through?”
Her smirk widened, predatory and teasing. “Yeah. You started something. You gonna finish it, or are you just gonna stand there looking like a deer in headlights?”
Swallowing hard, he took a step forward, his nerves jangling like loose change. Then, in a move fueled by pure instinct, he leaned in and planted a clumsy kiss on her lips. It was messy, all teeth and uncertainty, but Carol didn’t pull away. Instead, she chuckled against his mouth, her hands gripping his shoulders with a strength that reminded him she could bench-press a tank.
“Easy, tiger,” she murmured, pulling back just enough to look him in the eye. Her breath was warm, her gaze molten. “First time?”
He nodded, cheeks burning. “Is it that obvious?”
“Little bit,” she teased, brushing a thumb over his jaw. “But I like your enthusiasm. Let’s see if we can’t refine that raw talent of yours.”
Before he could stammer out a response, she kissed him back, hard and deliberate, her tongue sweeping in with a confidence that left him dizzy. His hands found her waist, hesitant at first, then bolder as she pressed herself against him. The heat of her body, the taste of her—salt and something electric—overwhelmed his senses. And then there was the other thing, the mutant quirk of his anatomy that made itself known as his arousal spiked. A subtle, involuntary pulse of energy coursed through his vibranium arm, sending a faint vibration through his touch.
Carol pulled back, gasping softly, her eyes wide with intrigue. “What the hell was that?”
Diego winced, mortified. “Uh, sorry, it’s… a thing. My arm, it’s wired into my nervous system, and when I get, y’know, worked up, it kinda… hums?”
She stared at him for a beat, then burst into laughter, the sound rich and unapologetic. “Hums? Kid, that’s not a hum. That’s a damn feature. You’re full of surprises, aren’t you?”
He ducked his head, embarrassed, but her fingers tilted his chin back up, forcing him to meet her gaze. “Don’t hide from me, Diego. I like surprises. And I like you. So, what do you say we take this upstairs? I’ve got a few tricks of my own to show you.”
His heart thundered in his chest, but he managed a shaky grin. “Upstairs sounds… educational.”
“Oh, it will be,” she purred, stepping back and jerking her head toward the door. “Come on, rookie. Let’s see if you can keep up with a real Avenger.”
As they exited the training room, the air between them crackled with unspoken promises, a charged tension that hinted at the wild, boundary-pushing journey ahead. Diego didn’t know what he was getting into, not really, but with Carol leading the charge, he was more than ready to find out.
