Chapter 9: Vanja straddles Karl-Heinz in his executive chair, her fingers tightening in his hair as she grinds her soaked pussy against the hard ridge of his cock through his suit pants. 'You want to play god with people's lives?' she snarls, tearing open his shirt as buttons scatter across the floor. She shoves his pants down just enough to free his thick cock, then sinks onto him with a sharp cry, riding him with punishing thrusts, her nails raking down his chest as she takes what she needs from him.
The slap cracked through the penthouse office, a sharp, dry sound like ice breaking. Karl-Heinz’s head snapped to the side. A faint, red bloom appeared on his cheek. He didn’t touch it. He slowly turned back, his eyes not angry, but amused. That was the worst part.
“Feel better?” he asked, his voice a low rumble.
“You don’t get to send him away,” Vanja said, her breath coming fast. The velvet of her gown felt like a suffocating skin. “You don’t get to punish him for my experiment.”
“It’s not punishment. It’s management. You introduced a virus; I’m containing the outbreak.” He leaned back against the edge of his polished desk, casually crossing his ankles. The city lights of Dortmund sprawled behind him like a spilled circuit board. “He’s a talented boy. He needs playing time. Bremen will provide that. Away from distractions.”
“Away from me.”
“Precisely.”
The calm logic was gasoline on the fire inside her. She stepped forward, closing the distance until the scent of his cigar and his cologne filled her senses. “You tried to control both of us. You used me to provoke him, and then you used him to punish me. You thought you were running the lab. But you lost control of your variables.”
His amusement faded, replaced by a cold, assessing stare. “I control everything in this world, draga. Every contract. Every transfer. Every headline. You and your… urges… are a contained element. A fascinating one, but contained nonetheless.”
“No.” The word was final. She grabbed the lapels of his tuxedo jacket, the fabric cool and smooth under her fingers. “You contain nothing.”
She kissed him. It wasn’t an offer. It was an assault. She crushed her lips against his, her teeth clashing with his, her tongue forcing entry into his mouth. She tasted the bitterness of his whiskey, the stale hint of cigar, and underneath it, the metallic flavor of her own rage. He stiffened, resisting for a fraction of a second, then his hands came up to grip her arms, not to push her away, but to hold her in place as he kissed her back with equal ferocity.
It was a battle fought in silence, a brutal exchange of dominance communicated through lips and teeth and clutching hands. She broke the kiss, gasping. “You’re not my keeper. You’re a subject. The most complex one I’ve ever had.”
She shoved him. He stumbled back, his thighs hitting the leather executive chair behind the desk. He fell into it with a grunt. Before he could rise, she was on him, hiking the black velvet of her gown up around her hips. She straddled him, her knees digging into the soft leather on either side of his thighs. The rigid outline of his cock pressed against her through his trousers and the damp silk of her underwear.
“You want containment?” she hissed, fumbling with his belt, her fingers clumsy with adrenaline. “Let me show you what an uncontrolled variable feels like.”
She got his belt open, his zipper down. She didn’t bother to undress him fully. She yanked his cock free, thick and already hardening in her furious grasp. She tore her own underwear aside, not even removing it, just shredding the lace at the seam. She positioned herself over him, her golden-green eyes locked on his blue ones, and impaled herself in one savage, downward thrust.
They both cried out. The penetration was too fast, too dry, a burning stretch that was all defiance and no grace. She winced, her inner muscles clenching in protest, but she didn’t stop. She began to move, riding him with a punishing, jagged rhythm, using her body as a weapon.
“You liked the data, didn’t you?” she panted, driving down onto him, the chair squeaking in protest beneath their weight. “You liked hearing how your son fucked me. It made you harder than anything else. Admit it.”
He gripped her hips, his fingers digging into the flesh just above the fresh bruises Leo had left. His face was a mask of conflicted lust and fury. “Shut up.”
“You came in the shower thinking about it,” she continued, leaning forward, her hands braced on the back of the chair behind his head. Her breasts heaved close to his face. “You were fucking his leftovers. Trying to reclaim your property. That’s all I am to you, right? Prime real estate.”
“I said shut up!” He bucked his hips upwards, spearing into her deeper, trying to derail her words with sensation.
It worked, for a second. A bolt of raw pleasure shot through her core, making her gasp. She adjusted, grinding against him, using the friction to fuel her own need. The initial pain had melted into a hot, slick ache. “You sent him to Bremen because you’re scared. Not of him. Of me. Of what I made you feel. Jealousy isn’t a controlled emotion, Karl-Heinz. It’s messy. It’s human. And you hate being human.”
He roared, a sound of pure frustration, and surged upward. He stood, still inside her, lifting her with him. He turned and slammed her down onto the cold, polished surface of the desk. Papers fluttered to the floor. A crystal paperweight rocked and fell, shattering on the hardwood. He pressed her down, his weight pinning her, his mouth finding her neck, biting, not a love bite but a brand.
“You want to see human?” he growled into her skin. He pulled out and flipped her over onto her stomach. Her velvet gown was tangled around her waist. He pushed her down, her cheek against the cool wood. “You want to see messy?”
He entered her again from behind, this time with a relentless, driving force. Each thrust drove her forward on the desk. This wasn’t the calculated power play of before. This was stripped bare, a raw reaction. He fucked her with a single-minded intensity, his hands gripping her shoulders, his hips slamming against her ass.
“You are mine,” he chanted, but it sounded like a plea now, not a declaration. “You will always be mine. Say it.”
She couldn’t form words. The desk rattled with their violence. The panoramic city view blurred in her vision. She was close, her climax building from a deep, dark place, fed by anger and the brutal, physical mastery of his motion. She reached a hand between her legs, her fingers finding her clit, swollen and throbbing. A few rough circles was all it took.
She came with a choked scream, her body clamping around him in vicious waves, her back arching. The orgasm felt like a rupture, a release of poison. It triggered his own. With a final, deep plunge, he emptied himself into her, a hot, claiming flood that spilled out onto her thighs and the dark wood of the desk.
He collapsed over her, his sweat soaking through the back of her gown. His breathing was ragged in her ear. For a long minute, there was only that sound, and the distant hum of the city.
He pushed himself up. He pulled out. The sudden emptiness was profound. She heard the soft rustle of him tucking himself away, zipping up. She didn’t move. She lay on the ruined desk, exposed and spent.
“The loan to Bremen is paperwork,” he said, his voice hollow, stripped of all its earlier certainty. “It can be delayed. Indefinitely.”
Vanja slowly pushed herself up. Her legs trembled. She turned to face him, pulling her gown down. She looked at him—the disheveled hair, the loosened bow tie, the stunned vacancy in his eyes. She had seen him after sex many times: sated, victorious, contemplative. Never this. Never like a fortress after the walls have been breached.
She walked to the bar, her heels crunching on the shattered crystal. She poured two fingers of his expensive Scotch, drank it in one burning gulp, and put the glass down.
“It’s too late,” she said, not looking at him. “The experiment is over. The results are in.”
“What results?” The question was barely a whisper.
She finally met his gaze. “You need my chaos more than I need your control.”
She left him there, standing amidst the wreckage of his office, his order, and his certainty. The door clicked shut behind her with a sound of finality.
In the silent elevator descending to the lobby, she leaned against the mirrored wall. Her reflection showed a woman with smeared lipstick, wild hair, and eyes that held a terrifying, crystalline clarity. The hollow feeling was gone, replaced by a cold, steady resolve.
She had her data. The thesis was writing itself. Now, she needed a new laboratory.
Now, she needed a new laboratory. Her own apartment felt too quiet, too academic, after the seismic rupture in Karl-Heinz’s office. She showered until the hot water ran cold, scrubbing the scent of him and the memory of her own compliance from her skin. The clarity remained, a cold, hard diamond in her chest.
Two days later, her phone buzzed on her desk, screen flashing with a Munich number she didn’t recognize. She let it ring three times before answering. “Vrantz.”
“He pulled the paperwork.” Leo’s voice was flat, devoid of its usual playful energy. “The Bremen move. It’s dead. I’m staying with the reserves for now.”
Vanja leaned back in her chair, staring at the thesis notes scattered before her. She said nothing.
“Did you do that?” he asked. The silence stretched, tense and thin. “Vanja?”
“I had a conversation,” she finally said, her voice carefully neutral. “The dynamics shifted.”
He let out a short, humorless laugh. “A conversation. Right.” Another pause. “I’m at the Hauptbahnhof. I took the train. Can I come over?”
This was the uncontrolled variable, returning to the source. She should say no. She opened her mouth to refuse. “Yes,” she heard herself say. “Text me the address of a cafe. I’ll meet you.”
She found him at a small table in the back of a crowded, steamy konditorei, a half-finished espresso before him. He looked older than she remembered, shadows under his eyes, his shoulders tense beneath a simple grey hoodie. The boyish grin was absent. He stood when he saw her, a gesture of old-fashioned courtesy that felt jarring.
“You didn’t have to come all this way,” she said, sliding into the chair opposite him.
“Yeah, I did.” He waited until she’d ordered a coffee before speaking again, his voice low. “He called me. Last night. He was… different. Not angry. Just quiet. He said my development was best served here, for now. Then he hung up.” Leo’s eyes, the same sharp blue as his father’s but softer, searched her face. “What did you say to him?”
Vanja stirred her coffee, watching the dark liquid swirl. “I told him the truth. That he was jealous. That he was human. He didn’t like it.”
A faint, surprised smile touched Leo’s lips. “You said that to his face?”
“Among other things.”
“He listens to you,” Leo said, wonder mixing with a new wariness in his tone.
“No,” Vanja corrected, meeting his gaze. “He heard me. There’s a difference.” She took a sip, the bitterness grounding her.
He blinked, then nodded slowly, understanding the formal closure she was offering. “Thank you,” he said, the words simple and direct. Then he leaned forward, his voice dropping further. “But that’s not why I came. I came for you. Not because of him.”
A warning bell chimed softly in her mind. “Leo…”
“I can’t stop thinking about it,” he interrupted, his earnestness brutal in its simplicity. “The gym. What it felt like. What you felt like. I’ve never… fuck, Vanja, you ruined me for anyone else.”
She felt the pull, the seductive lure of his uncomplicated desire. It was a clean flame compared to the toxic furnace with Karl-Heinz. And that was precisely the problem. She set her cup down with a definitive click. “I think we should stop. This can’t be healthy. You are only 19.”
He didn’t flinch. A spark of his old defiance returned. “And you are 26,” he said, a slow grin spreading across his face. It wasn’t boyish now; it was knowing. “And he is almost 50, so. What’s your point? Health? Since when is any of this about health?”
He had her there. Her entire thesis was about the unhealthy, powerful intersections of sport, power, and desire. She was a living case study in it. She stood up, throwing some euros on the table. “My point is it’s a bad idea. Go back to Munich. Train. Play football.”
He stood with her, following her out onto the damp Dortmund street. The afternoon light was weak, filtered through a blanket of grey cloud. “It’s a terrible idea,” he agreed, falling into step beside her. “So was provoking my father. You seem to specialize in terrible ideas.”
She kept walking, heading towards her apartment building, a silent admission. He followed, a persistent shadow. They didn’t speak in the elevator. The silence was thick, charged with the unspoken acknowledgment of where this was going. She unlocked her door, and he followed her inside.
Her apartment was all clean lines and books, a stark contrast to the opulence he was used to. He looked around, taking it in. This was her territory, her mind made physical. He seemed suddenly younger again, out of place.
“Last time,” she said, turning to face him, her back against her dining table. “This is the last time. Do you understand?”
He nodded, but his eyes were already stripping her. He closed the distance, and this time his kiss wasn’t exploratory or worshipful. It was hungry, possessive, fueled by weeks of frustration and the heady drug of having won a small victory. He kissed her like he was trying to consume the part of her that belonged to his father.
She met his hunger with her own, her hands fisting in his hoodie, pulling it over his head. His body was a marvel of young, dedicated athleticism, every muscle defined, skin smooth and hot under her palms. He pushed her robe off her shoulders, his mouth leaving hers to trail down her neck, to her breasts. He took a nipple into his mouth, sucking hard, his tongue flicking over the peak until she gasped.
“You think about this?” he muttered against her skin, his hand sliding down over her stomach, into the waistband of her shorts. “When you’re with him?”
“Don’t,” she warned, but her hips arched into his touch.
His fingers found her wet and already swollen. He pushed two inside her with a rough, eager thrust. “You’re so fucking wet. Is it for me? Or just because you’re thinking about telling him later?”
She cried out, the violation of the question and the precision of his fingers merging into one shocking bolt of pleasure. She didn’t answer. She couldn’t. She dragged him towards her bedroom, a tangle of limbs and desperate kisses.
He laid her back on the bed, yanking her shorts and underwear down her legs. He didn’t undress fully, just shoved his sweatpants and boxers down to his thighs. His cock sprang free, thick and flushed, the head glistening. He looked at her, spread before him, his chest heaving. “Tell me to stop,” he challenged, his voice rough.
She reached for him, wrapping her hand around his length, guiding him to her entrance. “Just fuck me, Leo.”
He drove into her in one deep, smooth stroke, burying himself to the hilt. The fullness was breathtaking, different from his father—less practiced, more urgent, hitting places with a youthful, accidental accuracy. He set a relentless, pounding rhythm from the start, his hips slapping against hers, the bedframe knocking the wall.
“You feel that?” he grunted, his eyes locked on where their bodies joined. “That’s me. Not him. Remember it.”
She wrapped her legs around his waist, pulling him deeper, meeting each thrust with a roll of her own hips. The crude ownership in his words, the blatant jealousy, should have repelled her. Instead, it ignited her. This was pure, id-driven reaction, a biology experiment stripped of all pretense.
“You like that?” she taunted, raking her nails down his back. “Marking his territory?”
He growled, a raw animal sound, and shifted, pulling her legs over his shoulders. The angle changed, and the head of his cock ground directly into a spot that made her vision whiten. She screamed, a short, sharp sound of pure sensory overload. He fucked her like that, deep and punishing, his control fraying with every stroke.
“I’m gonna come,” he warned, his rhythm becoming erratic, his thrusts shallower, harder. “Where do you want it?”
The vulgarity of the question, the sheer teenage filth of it, pushed her over the edge. “Inside me,” she demanded, her own orgasm roaring up from the base of her spine. “Fill me up, Leo. Do it.”
Her command shattered him. With a choked shout, he plunged deep and held, his body shuddering as he pulsed inside her. The hot, sudden flood triggered her own climax, a series of violent, clenching spasms that milked him dry. She clutched at him, her cries muffled against his shoulder.
He collapsed on top of her, his weight a solid, sweaty anchor. They lay there, gasping, the only sound their ragged breathing and the faint traffic from below. The space between them, once vast with power and generation, had collapsed into this damp, spent intimacy.
Slowly, he softened and slipped out of her. He rolled onto his back beside her, staring at her ceiling. The reality of what they’d done, the compounded transgression, settled over them like ash.
“That wasn’t a stop,” he said finally, his voice hoarse.
Vanja said nothing. She watched the grey light fade at her window. The laboratory was compromised. The variable had learned to talk back. He had, in his way, won. And she had the data to prove it.
And she had the data to prove it. The silence in her bedroom was a tangible thing, thick with spent energy and the souring smell of sex. Leo’s breathing beside her slowed, deepened. She could feel the damp patch cooling on the sheets beneath her. A fundamental line, once blurred, had been erased entirely. She had not just crossed it; she had burned the map.
“I should go,” he murmured, but made no move to get up. His hand found hers on the mattress, their fingers brushing. The gesture was unexpectedly tender, a jarring counterpoint to the animalistic fucking of minutes before.
“Your train,” she said, not a question. Her voice was detached, clinical. She was already mentally cataloging the session: the juvenile possessiveness, the reactive thrusting, the clear need to overwrite his father’s imprint. A textbook display of Oedipal competition, played out on her body.
“There’s another in an hour.” He rolled onto his side, propping his head on his hand. He studied her profile. “You’re doing it right now, aren’t you? The sociology shit. Breaking it down.”
“Sports psychology,” she corrected automatically. She turned her head to look at him. The post-coital vulnerability in his eyes was a richer data point than any thrust. “And yes. It’s what I do.”
He didn’t look hurt. He looked fascinated. “And what’s the verdict, Doctor?”
She sat up, the sheet pooling at her waist. The evening air was cool on her sweat-slicked skin. “The subject exhibits a pronounced territorial response, conflating sexual possession with personal validation. The act was primarily declarative, not connective.”
He blinked. Then he laughed, a real laugh that crinkled the corners of his eyes. “You’re fucking unbelievable. I just came inside you and you’re giving me a peer review.”
“You asked.” She allowed a small, tight smile. His laughter was disarming. It held no calculated menace like his father’s. It was just… light. A different kind of power.
“I did.” He sat up too, his shoulder warm against hers. He looked down at his own body, then at hers. “So, for the record. Was it better than him?”
The question hung in the air, crude and inevitable. She didn’t answer immediately. She reached out, tracing a line from his sternum down to the thatch of blond hair. Her fingers dipped lower, brushing his soft, spent cock. He twitched.
“Different,” she said finally. “Not better. It lacks context. History. The weight of consequence.”
“Consequence,” he repeated, as if tasting the word. He caught her hand, held it still against him. “This has consequences. For me. I can’t just… switch it off.”
There it was. The emotional stake. The variable developing its own consciousness. She had anticipated this, but hearing it was still inconvenient. She shifted, turning to kneel over him, her thighs framing his hips. She looked down at his face, at the open need there. “What do you want, Leo? What’s the desired outcome?”
“I want you to want me.” The answer was immediate, stripped bare. “Not for your thesis. Not to piss him off. Me.”
“That’s a complication,” she whispered, leaning down so her hair curtained their faces. Her lips were inches from his. “I don’t deal in complications. I deal in observations.”
“Then observe this.” His hands came up to grip her ass, hard. He was hardening again against her thigh, a swift, astonishing recovery. Youth. He guided her, rolling her over onto her back once more. He moved down the bed, his kisses a hot trail down her stomach. He didn’t ask. He hooked her legs over his shoulders, his breath hot on her inner thighs.
He ate her out with a focused, desperate intensity. His tongue was flat and broad, licking up the mix of their fluids from before. He zeroed in on her clit, sucking the swollen bud into his mouth, applying a steady, rhythmic pressure that made her back arch off the bed. He was learning, adapting, using the feedback of her gasps and shudders to refine his technique. This wasn’t just about his pleasure anymore; it was a performance, an audition for a permanent role.
“Fuck, Leo, right there,” she hissed, her fingers tangling in his hair, not pushing him away but holding him precisely in place. The orgasm built quickly, a tight, hot coil in her lower belly. It was less volcanic than the first, but deeper, a spreading warmth that melted her clinical distance. She came with a low, shuddering moan, her hips bucking against his mouth.
He didn’t let up, gentling his tongue but continuing to lap at her through the fluttering pulses, drinking her in. When she finally pushed at his shoulders, he moved up her body. His cock, now fully rigid, nudged against her slick, sensitized entrance.
“Tell me you feel something,” he demanded, his voice ragged. He didn’t push in. He waited.
For a long moment, she just stared up at him, at the desperate hope etched on his face. The data stream was a chaotic jumble now: physiological response, psychological manipulation, genuine affection. She couldn’t parse it. She kissed him, a slow, deep kiss, tasting herself on his lips.
“I feel,” she said against his mouth. It wasn’t a lie. It just wasn’t the whole truth.
It was enough. He sank into her, a slow, deep glide this time. The pace was different, more measured, but no less intense. He fucked her with a reverent urgency, his eyes open, watching every flicker on her face. Each stroke was a question. Each gasp was an answer. He was mapping her, learning the architecture of her pleasure with a dedication that felt dangerously like devotion.
“You’re so tight,” he breathed, his forehead damp against hers. “Even now. God, Vanja.” His control began to slip, his thrusts gaining speed, losing their precision. “I’m not going to last. Come with me. Please.”
He was begging. The son of Karl-Heinz Rummenigge was begging her to come. The power of it was absolute, a narcotic more potent than any orgasm. She wrapped her legs around him, locking her ankles at the small of his back. She met his frantic rhythm, her own climax gathering again, fed by his utter surrender.
“Let go,” she commanded, her voice a guttural whisper in his ear. It was the permission he needed. With a broken cry, he drove into her one final time, his body seizing as he emptied himself. The hot, pulsing rush triggered her own release, a second, softer wave that clenched around him, milking every last drop.
He collapsed, his full weight on her, but she didn’t mind. She held him as he shuddered, stroking his damp hair. The city lights through her window painted shifting patterns on the wall. The lab was irrevocably contaminated. The subject had become a collaborator.
A long time later, he stirred. He slid out of her and off the bed, moving quietly in the dim room. She heard the soft sounds of him dressing. She watched him from the pillow, a silhouette reassembling itself into Leo Rummenigge, footballer.
He sat on the edge of the bed to pull on his shoes. He didn’t look at her. “I’ll be back next weekend. For the derby.”
“You shouldn’t.”
“I know.” He stood, finally turning. His expression was unreadable in the dark. “The data will be interesting, right?”
He left, closing her apartment door with a soft click. Vanja lay perfectly still. The scent of him, of them, was everywhere. She reached for her notebook on the bedside table. She didn’t turn on the light. In the dark, she wrote a single line, the words stark and simple beneath her fingertips.
Subject L has altered the parameters of the study.
