Kallen stood there, her fists clenched at her sides, her chest rising and falling with shallow, furious breaths. Her Black Knights uniform clung to her frame, dusted with ash and dirt from her mad rush to the base.
Zero, Lelouch, faced her silently while he thought of something to say.
The other Black Knights were too busy celebrating or tending the wounded to notice the tension thickening between their captain and their masked leader.
"Kallen," Lelouch said calmly with a hint of sharpness behind it, his voice cutting through the silence like a blade. "You should not be here."
She stiffened.
"You were supposed to stay at Ashford Academy," he continued, stepping closer. "Maintain your cover. Stay safe. Focus on school. That was the plan. Do not ask me how I know, I just do."
Kallen raised her head defiantly, her blue eyes flashing. "I saw the broadcast. I thought you guys needed backup. I couldn't have just stayed at school while you all were out fighting!"
"You could have," Lelouch interrupted, voice sharp. "You should have."
Kallen's mouth opened in protest, but Lelouch closed the distance between them in three measured steps. He grabbed her wrist and led her away from the center of the hideout into a private abandoned room away from the celebrating Black Knights and the activities happening over there.
"You disobeyed," he said, his tone dropping lower, darker. "You abandoned your post. You risked exposure."
"I just wanted to help—" she started, but Lelouch silenced her with a single gloved hand wrapping lightly around her throat, tilting her chin up until her mouth closed with a gasp.
"You were a bad girl, Kallen," Lelouch whispered dangerously against her ear. "And bad girls need to be punished."
Her entire body trembled. Not with fear, but with anticipation. She couldn't look away from him. The imposing figure of Zero loomed over her, with the power radiating off him in waves.
"You should be grateful I'm the one punishing you," Lelouch said, smirking under the mask. "Anyone else would have thrown you in a cell. You have to be careful who you approach."
Kallen's breath hitched.
"Take off your jacket," he commanded with his Geass.
She hesitated, for a second, but the fire in his voice and eyes didn't let her.
With shaking fingers, she slipped the zipper down and shrugged the tight fabric off her shoulders, letting it fall to the dusty ground. Her red undershirt clung to her curves, the black straps of her tactical bra visible beneath. The shirt matched her hair perfectly. She was almost too hot. Lelouch moved like a predator to its prey.
He grabbed her wrists and pinned them high above her head against the rough wall behind her. She gasped, her body arching instinctively, her breasts pressing against the thin fabric between them.
"You need to understand," Lelouch said, voice low and seething. "You belong to me. You fight when I tell you to. You bleed when I command it. You risk your life only when I allow it."
Kallen moaned softly at the dominance in his voice, her thighs clenching together.
"And if you disobey again…" Lelouch growled, nipping sharply at her earlobe through the mask, "the punishment will be far worse than this." He took off his mask and used his Geass to command Kallen to never tell anyone his identity. Lelouch then took off his mask, happy to show his true self. Kallen stood there for a moment, shocked.
Without warning, he crashed his mouth onto hers with fierce passion.
Kallen kissed him back hungrily, letting out a soft whimper into his mouth as he ravaged her, biting and licking and stealing every breath from her lungs. She tugged helplessly at her pinned wrists, desperate to touch him, to claw at him, but Lelouch held her fast.
One hand holding her wrists above her head, his other hand slid roughly down her body, tracing her curves, squeezing her breast through the thin fabric of her undershirt, pinching her hardened nipple between his fingers until she gasped.
"Lelouch," she moaned breathlessly.
"Shh," he growled. "You'll address me properly as master."
"Master," she gasped, her body practically melting against him.
"Good girl," Lelouch purred.
He yanked her shirt up, exposing her toned stomach and the lacy black bra barely containing her heaving chest. He kissed down her jawline, her throat, her collarbone, leaving bruising marks in his wake. Kallen shivered against him, desperate and dizzy with desire.
Still holding her wrists with one hand, Lelouch used the other to rip the front of her bra open, the fabric giving way with a satisfying snap. Her breasts bounced free, nipples exposed in the cool air of the abandoned city.
"Beautiful," Lelouch muttered darkly against her skin.
He leaned down and took one of her nipples into his mouth, sucking hard, swirling his tongue around the sensitive bud until Kallen arched off the wall with a cry. Her legs trembled. Her panties were soaked.
"Please," she whimpered.
"Please what?" Lelouch demanded, pinching her nipple roughly.
"Please... punish me," she whispered, shamed but shameless, wanting him, needing him.
That was all the permission he needed. He let go of her wrists. She immediately wrapped her arms around his neck, pulling him into another bruising kiss. Lelouch's hands moved fast now, yanking her tight combat pants down her legs, ripping them past her boots. He found her soaked panties, delicate and black, and slid a gloved finger along her dripping vagina.
"So wet for your punishment, my slut," he mocked.
"Only for you," she gasped.
He tore the panties aside and unzipped his own pants, freeing his hard, throbbing cock from the confines of the fabric. Kallen's eyes widened slightly as she looked down at him, but she bit her lip and said nothing, letting her body speak for her instead as she spread her legs wider, offering herself to him without shame.
Lelouch growled, grabbing her thighs and lifting her easily off the ground. She wrapped her legs around his waist, locking herself to him. He lined himself up with her entrance: wet, hot, desperate, and thrust into her in one hard, brutal motion.
Kallen threw her head back against the wall, crying out in pleasure. Lelouch groaned low in his throat, feeling her tightness clamp down around him. He didn't give her time to adjust. He set a hard, punishing pace. He immediately drove his cock into her over and over again, slamming her back against the wall with each deep thrust.
"You're mine," he grunted into her ear. "Say it, shithead."
"I'm yours," she cried, nails digging into his shoulders.
He kissed her again and again while swallowing every moan, every cry of pleasure. Their bodies moved as one as they clung to every sensation they were feeling. She climaxed first, gasping his name into the night air. Lelouch wasn't far behind. With a final deep thrust, he came hard inside her, groaning against her throat as he emptied himself into her. Her legs trembled.
They stayed locked together for a long moment, breathing heavily, hearts pounding in sync.
Finally, Lelouch pulled back slightly, brushing a lock of her damp red hair from her flushed face.
He kissed her forehead, softer this time.
"You don't have to prove anything to me," he whispered against her skin. "You're already mine. Now be a good girl and do what I say or else the punishment will be a lot worse. If you want praise, bitch, you have to earn it. No putting yourself in danger if I tell you no, ever again. You understand?"
Kallen smiled weakly while nodding, resting her forehead against his shoulder.
"Good girl," Lelouch said as he smiled and hugged her.
