The fluorescent lights of the military base hummed overhead, casting sterile white light across the cold concrete walls. For twenty years, Petra had been their perfect weapon—silent, unstoppable, and utterly obedient. The super-soldier project had created her in a lab, engineering her from the genetic level upward. Five times stronger, five times faster, and carrying the one feature they hadn’t anticipated: a thick, heavy cock and heavy balls between her powerful thighs.
Now at forty-plus, her edge had dulled just enough for the brass to see her as expendable in the field. But not worthless. Not when they still couldn’t replicate what made her.
The Major’s office smelled of old coffee and gun oil. He didn’t waste time.
“You’re done with black ops,” he said flatly. “New assignment. Long-term. You’re going to breed more soldiers like you. The old-fashioned way.”
Petra’s jaw tightened, the only crack in her iron composure. “Sir?”
“You heard me. Get out. You’ll figure it out when you get back to your quarters.”
The door clicked shut behind her with finality.
When she stepped into her room, the young woman was already there—bare legs dangling off the edge of the single bed, wearing nothing but a thin white t-shirt and plain cotton panties. Her pants lay crumpled on the floor like she’d been told to strip quickly and wait.
“Who are you?” Petra asked, voice low.
The girl twisted her fingers together. “They said I’m not allowed to give my name. Just that you’d… understand.”
Petra studied her. Early twenties at most. Fresh from basic, probably. “I’d like to know we’re on the same page.”
“When I finished training they pulled me for a ‘special operation.’ Said I might be compatible. So… here I am.”
Petra sat beside her, the mattress dipping under her muscled weight. “They want you pregnant. You understand that?”
“Yes.” The girl’s voice was small but steady. “I’m doing it for my country.”
“Very well.” Petra leaned in.
Their first kiss was awkward. The girl’s lips trembled, uncertain, tasting faintly of mint toothpaste. Petra guided her, one large hand cupping the back of her neck, tongue sliding past parted lips to explore. The recruit made a soft sound—half surprise, half surrender—and Petra deepened the kiss, tasting her nervousness.
Clothes came off slowly. Petra peeled the white t-shirt upward, revealing small, perky breasts with pink nipples already tight from the cool air. The cotton panties followed, sliding down smooth thighs. The girl stared openly when Petra stripped, eyes widening at the heavy cock rising between her legs—thick, veined, already half-hard and darkening at the tip.
“That’s… classified,” Petra said before the question could form.
She laid the girl back on the narrow bed. The recruit’s thighs parted instinctively, knees falling open. Petra settled between them, one hand braced beside the girl’s head, the other guiding her cock. The blunt head pressed against slick folds, parting them. She pushed forward in a slow, steady thrust.
“Ah—” The girl gasped as the thick shaft stretched her open. Petra moved inch by inch, feeling tight heat grip every ridge and vein. Halfway in, she paused, letting the recruit adjust, then pushed deeper until her hips met the girl’s and her balls rested against smooth skin.
“Fuck, you’re tight,” Petra breathed.
She started with long, deliberate strokes—pulling almost all the way out before sinking back in. The wet sound of each thrust filled the small room. The girl’s pussy clenched around her, slick and hot, coating the shaft in glistening arousal. Petra’s pace gradually increased, hips rolling with controlled power. Each thrust made the bed frame creak.
“Oh god—” The girl moaned, fingers digging into Petra’s muscled shoulders. “It’s so deep—”
Petra fucked her steadily, sweat beading on her brow, her heavy breasts swaying with the motion. The girl’s inner walls fluttered and squeezed, trying to draw her deeper. Petra angled her hips, grinding against the girl’s clit with each downward stroke. The recruit’s back arched, heels digging into the mattress.
“I’m—I’m close—” the girl whimpered.
Petra didn’t slow. She drove in harder, the wet slap of skin on skin echoing. The girl’s orgasm hit first—her pussy spasming around the thick cock, a broken cry escaping her throat. Petra kept thrusting through it, prolonging the pleasure until the recruit was trembling beneath her, fear in her eyes for what about to happen and change her life forever.
“I’m sorry, honey,” Petra murmured as her own climax built. “It’ll be over soon.”
Her balls tightened. With a low groan she buried herself to the hilt and came hard—thick ropes of cum pulsing deep into the girl’s womb. The force of it made the recruit gasp, feeling the hot flood fill her. Petra stayed inside, hips twitching with aftershocks, seed carrying her special trait seeking to create a new life.
Weeks turned into months. Every seven days a new young woman waited in Petra’s room—different faces, same orders. Petra performed her duty with mechanical precision, but something inside her fractured a little more each time. She saw the pattern: these girls weren’t volunteers. They were assets. Just like she had been.
One night, after the latest “recruit” had left with Petra’s cum still leaking down her thighs, something snapped. Petra gathered what little she needed, slipped past security using skills honed over two decades of black ops, and vanished into the night.
Her mission now was simple: find every child the military had forced her to create—and make sure none of them became weapons.
