After a long day of combat training and taunting, Luna challenges Kaiden to a friendly spar. She aims to test her speed against his strength, but Kaiden uses her own recklessness to corner her. He pins her down, only to discover she was already aroused, leading to a more intimate encounter.

Kaiden grinned. "Serious Series: Obliterating Fingers."

"So CORNY- ANNHGGHH!!!"

He worked her, firm and relentless, his fingers moving with the kind of confident, direct pressure that he knew turned Luna from a foul-mouthed gremlin into a shaking mess. His forearm corded with the effort of keeping her wrists locked while his other hand destroyed her composure from the inside out, and she watched his arm flex with every movement through half-lidded eyes that had given up on anger and settled for hunger.

"Ahn-! Nnh- you- fuck-"

*Pap. Pap. Pap.*

The wet sound of his fingers filled the training room and Luna’s legs fell open wider, giving him access she would have died before admitting she wanted, and her hips rolled against his hand in a desperate grind.

"Kai- I’m- fuck, I’m going to-"

He instantly withdrew his hand.

The scream she produced could have stripped paint. "I’LL KILL YOU! PUT IT BACK RIGHT NOW OR I SWEAR ON EVERY-"

"So." He looked down at her, pinned and ruined and flushed from her collarbones to her hairline. "What’s the prize?"

Luna’s grin came back, but it was wrecked. Trembling at the corners, bravado doing real work to hold itself together over a foundation of want so obvious it was almost sad.

"A second round..." she murmured bashfully, cheeks hot.

He kissed her.

"Mmm!" Luna made a sound against his mouth, sharp and startled, and then her whole body surged against his, not to escape but to get closer. Her wrists strained against his grip because she wanted her hands on him and he wasn’t letting her have them, and the frustration of it came out as a growl into his mouth that vibrated through his teeth.

He let go of one wrist. She immediately grabbed a fistful of his shirt and hauled him down harder against her, kissing him with the same ferocity she brought to everything, teeth and tongue and zero patience.

She got a hand free and tried to roll him. Genuinely tried. She hooked her leg around his hip and threw her weight sideways, and for half a second she almost had it, her body leveraging his momentum, and he caught her mid-roll and pinned her again, flat on her back, both wrists above her head.

"Hn!" She glared up at him, panting, furious, aroused. "Let me-"

"This is the second round. Fight back with all your might, my adorable Luna~"

He kissed her neck. She arched into it, cursed, tried to flip him again. This time he caught her leg with his and scissored her flat, and she gasped as his weight settled heavier across her hips.

"You’re such a- hn- fucking-"

He pulled her tank top over her head in one motion. She helped, arms up, because even Luna’s stubbornness couldn’t compete with wanting his hands on her. The garment sailed somewhere behind them. She was petite beneath him, and when his hand spread across her bare stomach it covered most of the real estate.

She tried to roll him again.

He let her get halfway, let her feel the triumph of almost winning, and then reversed her back down onto the mat with his palm flat between her shoulder blades. Her cheek hit the padding and she snarled.

"THAT is cheating-"

His mouth found the back of her neck and the snarl dissolved into a hiss and her fingers clawed the mat. He kissed down her spine and she shivered and stopped fighting and started arching into him instead, and the line between wrestling and foreplay vanished.

He flipped her onto her back again. She kicked her shorts off herself because waiting for him was intolerable. He pinned her wrists above her head, one-handed, and used the other hand to touch her the way he’d learned she liked: firm, direct, no teasing.

"Ahh!" Her back came off the mat. "Fuck- right there, yeah-"

He stopped.

"I’LL KILL YOU."

He resumed.

*Pap. Pap. Pap.*

She tried to flip him one more time. Her leg hooked around his waist and she threw her weight and he caught her mid-roll and drove into her and the attempt at supremacy became a moan she didn’t plan.

"Ahn!"

The competitive energy burned through the sex like fuel. Every time he pushed her down she pushed back, every time she gained an inch of leverage he took two, and the wrestling continued even after he was inside her, her body fighting his for position while the pleasure built in both of them.

She got on top once. Straddling him, victorious for exactly three seconds, grinning down at him with her hair wild and her chest bare and her hips rolling. "Ha! Now who’s-"

He sat up, caught her by the waist, and flipped her underneath him in one motion. Her back hit the mat and he was inside her again before she’d finished gasping.

"Fuck you!" She wrapped her legs around him and the "fuck you" became "fuck me" so fast it tripped over its own consonants and landed as "fhh-" and then there were no words at all.

*Pap. Pap. Pap. Pap.*

He pounded her, hard, relentless, her body jolting against his with every thrust.

Her trash talk died first. Then her cursing. Then even the moans went quiet, until the only sound she made was his name, breathless and raw and stripped of every defense she’d ever built.

"Kai..." Her voice came out different. Quiet. Almost lost beneath the sound of their bodies. The aggression had burned off like morning fog and what was underneath it was just Luna, with her guard down, pressed against the only person she’d ever let see her like this.

"I always thought-" She gasped as he hit the angle again, her words coming in fragments between thrusts. "Before I met you- ahn- I figured the guy I’d end up with would be- hah- quiet. Obedient. Someone I could boss around."

He didn’t stop. He didn’t slow down. He kept pounding her while she spoke, and the words came out broken and breathless and more honest for it.

"I thought that’s what I wanted. Some submissive guy who’d- nnh- do whatever I said and never push back." A wet, shaking laugh. "And then you happened."

Her legs tightened around him. Her eyes found his, bright and glassy and completely unguarded.

"And you pin me down and you don’t listen and you’re stronger than me and I can’t- ah- make you do anything, and it’s..." Her voice cracked, right there on the edge of something she’d never said aloud, while he was buried inside her and moving and she couldn’t hide behind a single thing. "It’s so much better. I love it. I love being overpowered by you. I love being used by you."

The words sat there, raw and devastating. Luna said "bitch" and "cunt" to strangers without blinking, but this admission, delivered while he fucked her senseless, had cost her something real.

He kissed her.

She melted into it, her whole body softening against his even as his pace stayed brutal. She moaned into his mouth, a sound that went through him like voltage. Her legs tightened, her fingers dug in, and she whispered "Kai" one more time, just his name, just that, before she came undone.

"Haahnggh!!"

Her body clenched around him and she shuddered in his arms, held off the ground, trembling through every wave of it. He followed her over the edge a moment later, pulling her down against him as he came inside her, the sound he made low and buried in her hair, and she gasped at the warmth of it and pressed herself closer and shook.

They held there, breathing, heartbeats slamming against each other through their ribs.

Luna’s forehead rested against his collarbone. Her arms stayed around his neck. She was trembling with aftershocks, her legs still locked around his waist, and for ten seconds she was just a girl, small and breathless and happy.

Then Kaiden’s head snapped up.

His body went rigid. A presence, seated and unmoving, that had been there long enough he should have felt it earlier. He hadn’t, because Luna had been very, very distracting.

The corner of the training room was dark. The bench against the far wall was occupied.
