At the same time, Rebecca was busy producing additional supplies of the T-Virus vaccine.
The room was filled with the low hum of laboratory equipment, monitors displaying streams of data, and the sharp scent of disinfectant that lingered in the air.
Standing in front of the workbench, Rebecca remained completely focused on her task. Her eyes carefully tracked the data on the monitors while her hands moved with practiced precision, adjusting samples and checking the progress of the vaccine formula.
However, just as Rebecca was completely focused on the computer monitor, she was suddenly pulled into an embrace from behind.
"Hey, sweetheart… why don't you take a break for a while?" Allen said softly as he wrapped his arms around her waist and gently pulled her against him.
"Just a little longer, okay?" Rebecca replied without taking her eyes off her work. "The next batch of vaccines is almost ready."
Despite her words, she made no effort to pull away from Allen's embrace.
Instead, she leaned back slightly against him and let out a quiet breath.
Allen rested his chin lightly on her shoulder, watching the data scroll across the screen.
"You've been pushing yourself nonstop," he said calmly. "I know how important this is… but you need to rest too."
Rebecca gave a faint smile, her shoulders relaxing as she allowed herself to pause for just a moment.
"I know," she murmured. "It's just… if we can finish this, it could save a lot of people."
Allen could only let out a quiet sigh at how stubborn Rebecca could be.
Then, a rather mischievous idea crossed his mind—one that might actually convince her to get some proper rest tonight.
Sure enough, his hands moved toward the buttons of the lab coat Rebecca was wearing, slowly beginning to undo them.
Rebecca was still focused on preparing the nearly completed T-virus vaccine, her attention fixed on the work in front of her. However, she soon noticed what Allen was doing and blinked in surprise.
"Ahh... Allen, can we do this later?" she said, because Allen had just gently pinched her nipple.
But despite that, Rebecca didn't refuse the way Allen was handling her body right now.
Allen slowly kissed Rebecca's neck, inhaling the jasmine-like scent of her skin, which only fueled his desire to explore every inch of her doll-like figure.
Allen also began to slowly strip off all his clothes.
Then, he lifted Rebecca's body as she sat there.
"S—Sweetheart, wait at least~ Ahhh," but before she could finish her sentence, Allen's cock plunged into her pussy, piercing straight through to her womb.
Because Allen's cock was so thick and long, her petite belly visibly bulged from the intrusion.
"Ough, ahhh, Allen, go slow, uhhh, my hand," she gasped, her fingers trembling as she clutched the bottle of chemical solution.
Rebecca's lab was a sterile haven of beakers, test tubes, and humming machinery, but in that moment, it transformed into a playground of forbidden passion.
The vaccine mixture bubbled softly on the counter, mere seconds from completion, yet Allen couldn't hold back any longer. His strong arms hoisted her slight frame effortlessly onto the edge of the workbench, scattering a few pipettes in the process. Her lab coat hung open, exposing the lacy bra that barely contained her perky breasts, nipples already hardened from his teasing touch.
Allen's lips trailed fire along her collarbone as he ground his hips forward, burying his massive shaft deeper inside her tight, welcoming heat.
The bulge in her abdomen was unmistakable—a lewd outline of his girth stretching her from within.
Rebecca's breath hitched, her free hand instinctively gripping his shoulder for support while the other arm extended awkwardly, desperate not to spill the precious vial. The chemical liquid sloshed dangerously, mirroring the way her juices coated his throbbing length with each shallow thrust.
"Fuck, Rebecca, you feel so goddamn perfect," Allen growled against her ear, his voice husky with lust.
He nipped at her earlobe before capturing her mouth in a hungry kiss, tongues tangling as he began to pump in and out with deliberate slowness.
Her pussy clenched around him like a vice, milking his cock as if begging for more despite her protests. The scent of jasmine mingled with the sharp tang of lab chemicals and the musky aroma of their arousal, creating an intoxicating haze.
She moaned into his mouth, her body betraying her words as her legs wrapped around his waist, pulling him closer. The workbench creaked under their weight, vials rattling precariously.
Allen's hands roamed freely now—one sliding up to cup her breast, thumb flicking over the sensitive bud of her nipple, while the other steadied her hip, guiding her onto him with each roll of his pelvis. He could feel the head of his cock nudging against her womb, sending jolts of pleasure through both of them.
"Allen... oh god, it's too big," Rebecca whimpered, her voice breaking as another tremor shook her hand.
A drop of the chemical escaped the bottle, sizzling faintly on the counter, but she didn't care anymore. The vaccine could wait; the fire building in her core demanded attention. She set the vial down with a clink, both hands now free to claw at his back, nails digging into his skin as he picked up the pace.
He thrust harder, the wet slap of skin on skin echoing through the lab. Her small body jolted with every impact, breasts bouncing enticingly.
Allen broke the kiss to trail his mouth downward, sucking one nipple into his hot mouth while pinching the other. Rebecca arched her back, crying out as waves of ecstasy rippled through her. Her pussy fluttered around his invading cock, walls rippling in rhythm with his movements.
"That's it, baby, take all of me," he urged, his breath ragged. He hooked one of her legs over his arm, angling deeper, hitting that sweet spot inside her that made stars explode behind her eyelids. Precum mixed with her slickness, easing the way for his relentless pounding. The bulge in her belly shifted with each plunge, a visual testament to how completely he filled her.
Rebecca's climax built like a storm, her thighs quivering as she ground against him. "Allen, I'm... I'm gonna cum," she panted, her voice a mix of plea and command.
He grinned wickedly, slamming into her one final time before feeling her shatter around him—her pussy spasming, gushing fluids that soaked his balls and dripped onto the lab floor.
But Allen wasn't done. With a primal grunt, he flipped her over, bending her across the workbench so her ass was presented to him like an offering.
Her lab coat draped over her back, but he yanked it aside, exposing her round cheeks. He spread them wide, admiring the way her pussy lips glistened, stretched from his earlier assault.
Without hesitation, he drove back in, fucking her from behind with renewed vigor.
The new position allowed him to go even deeper, his hips slapping against her ass as he gripped her waist.
Rebecca braced herself on the counter, knocking over a stack of notes, but the chaos only heightened the thrill. "Ahh.. yes harder, Allen, fuck me harder," she begged now, fully surrendered to the moment.
He obliged, one hand reaching around to rub her swollen clit in tight circles, the other tangling in her hair to pull her head back for another bruising kiss.
Sweat slicked their bodies, the lab's cool air doing nothing to temper the heat between them.
Allen's balls tightened, the pressure building as her tight channel squeezed him relentlessly. "Gonna fill you up, Rebecca," he warned, thrusts turning erratic. She pushed back against him, meeting every stroke, until he roared his release—hot ropes of his yogurt flooding her womb, overflowing and trickling down her thighs.
She collapsed against the workbench, her body limp and spent, chest rising and falling in heavy pants as the vaccine project slipped from her mind entirely in the euphoric fog of their shared release. But as their ragged breaths gradually steadied into a more rhythmic cadence, Rebecca lifted her gaze, her face still glowing with a post-orgasmic flush, and eyed the bubbling mixture on the counter with a sly, knowing smile that hinted at her playful intentions.
"Now... can I continue my work for a bit?" she asked, her voice breathy and laced with lingering desire.
However, true to her words' unspoken promise, she didn't make any effort to pull away from Allen's cock, which stayed lodged deep within her, the thick head pressing insistently against the tight ring of her womb, keeping her pussy stretched wide and filled to the brim with his persistent presence.
Allen chuckled deeply, the sound vibrating through his chest as he remained buried to the hilt inside her slick heat, his body already responding with a fresh twitch of arousal, gearing up for another round of indulgence. The lab's sterile air hung heavy with the mingled scents of sex and chemicals, her jasmine perfume clinging to his skin like an aphrodisiac.
"Well, okay," he replied, his voice rough with satisfaction and renewed hunger, "but how about you make that vaccine while I move slowly inside you?" It was clear from the way his hips shifted ever so slightly that he craved the enveloping warmth of his lover's core, unwilling to relinquish the velvet grip of her walls just yet.
He savored the way her pussy fluttered around his shaft, still sensitive and dripping with their combined fluids.
"Ahhh, yes, but please don't move too fast, okay?" Rebecca responded, her tone a blend of reluctant surrender and subtle invitation. She had given in completely, allowing Allen to use her body however he pleased in this moment of vulnerability.
Truth be told, she was still a little horny herself—their intense session had left embers of lust smoldering within her—so it wasn't an issue at all; if anything, it added a thrilling edge to her focus.
"Okay, then I'll move slowly," Allen assured her, his words accompanied by the gentle sway of his hips as he began to rock them with controlled tenderness.
He eased back a fraction, feeling her inner muscles cling to his retreating length, before pushing forward again, the motion deliberate and unhurried, designed to tease rather than overwhelm.
This subtle rhythm caused Rebecca's eyes to drift shut, her lashes fluttering as waves of pleasure rippled through her from the renewed activity of Allen's cock sliding within her depths.
The sensation was intoxicating, her body responding instinctively to the familiar invasion.
Yet, even amidst the building ecstasy, she reached out with a trembling hand, retrieving the reaction bottle once more and resuming her scientific duties.
She carefully measured and added components to the mixture, all while permitting Allen to continue thrusting into her hypersensitive pussy, each slow glide sending sparks of delight coursing up her spine.
Her clit throbbed with every pass of his body against hers, and she bit her lip to stifle a moan, determined to see the task through.
And when she finally placed the last reagent into the swirling concoction, watching it react with a final fizz and color shift, her body betrayed her completely—instead of triumph, a powerful climax crashed over her without warning.
"Ahhh!" she cried out, her voice echoing off the lab walls as her pussy clamped down hard around Allen's cock, spasming wildly in rhythmic contractions.
Her legs quivered beneath her, juices gushing out to coat his balls and drip onto the floor, her hands gripping the edge of the workbench for support as stars burst behind her closed eyelids.
The orgasm ripped through her core, her womb fluttering against his tip, pulling him deeper as if to milk every drop of pleasure from the moment. Allen groaned at the sudden tightness, his own arousal spiking as he held still, letting her ride the waves while buried inside her pulsing heat.
Rebecca's voice trembled with a mix of exhaustion and renewed hunger as she finally sealed the finished vaccine vials into their protective box, her legs shaking uncontrollably beneath her from the aftershocks of her climax. The lab counter was slick with their mingled fluids, the air thick with the sharp tang of chemicals and the musky evidence of their passion.
"Yes, ahh, Allen, everything is sorted out now.," she gasped, her words spilling out in a breathless rush, "and I think you can move faster now." Her pussy clenched around his thick shaft instinctively, urging him on now that her work was complete, the sensitive walls still fluttering from the earlier orgasm.
Allen grinned wickedly at her permission, his hands gripping her hips firmly as he wasted no time. Without a word, he hoisted her lightweight body up from the workbench, her legs wrapping around his waist on reflex while her arms looped around his neck for support.
Her lab coat hung open, exposing her flushed breasts that bounced with the sudden movement, nipples hard and begging for attention. He positioned her just right, his massive cock—still rock-hard and slick with her juices—thrusting upward with brutal force as he began to pump into her relentlessly. Each powerful stroke slammed deep, the head battering against her cervix, making her belly distend visibly with every invasion.
"Ahh! Uhgg yes Allen!" Rebecca cried out, her moans echoing through the sterile lab once more, raw and unrestrained. Her head fell back, exposing the curve of her neck as waves of pleasure-pain ripped through her core. He bounced her on his length like a ragdoll, his muscles flexing under her weight, driving his hips up to meet her descending body. The wet slap of skin on skin filled the room, punctuated by the squelch of his cock plunging into her overflowing pussy. She clawed at his shoulders, nails digging into flesh, as he fucked her standing, her juices trickling down his balls and thighs in hot rivulets.
He didn't let up, shifting his grip to her ass cheeks, spreading them wide to allow even deeper penetration. Round one blurred into the next as he carried her to a nearby stool, sitting down with her impaled on him, her knees splayed on either side. Rebecca rode him instinctively at first, grinding her clit against his pubic bone, but Allen took control, bucking up into her with savage intensity. "You are mine now," he growled, capturing a nipple between his teeth and sucking hard, the pull sending jolts straight to her clit. She screamed in ecstasy, her pussy spasming around him as another orgasm built rapidly.
By the second round, he had her bent over the lab table again, her face pressed against the cool surface amid scattered notes and equipment. Allen stood behind her, one hand fisting her hair to arch her back, the other pinning her wrist as he rammed into her from behind. His cock stretched her limits, the girth making her walls burn with delicious friction.
"More...deeply~," she begged between sobs of pleasure, pushing back to meet his thrusts. He obliged, pounding harder, his balls slapping against her swollen clit until she shattered, squirting forcefully around his shaft, her fluids spraying across the floor like a burst dam.
Sweat dripped from his brow onto her back as he chased his own release, but he held back, flipping her onto her back for the third round. Legs hooked over his shoulders, he folded her nearly in half, drilling down with piston-like precision. Rebecca's eyes rolled back, her mouth open in a continuous wail as his cock reshaped her insides. The pressure built unbearably in her belly, a strange swelling forming from the relentless filling—her womb bloated from the sheer volume of his pre-cum and her own gushing responses, mimicking the roundness of a three-month pregnancy. She looked down in dazed wonder, her hands pressing against the taut skin, feeling it bulge with each thrust.
"Allen... ugh... ahh!" Her words dissolved into incoherent moans as the fourth round pushed her beyond endurance. He had her against the wall now, her body pinned between him and the cold tile, his arms caging her in as he fucked upward with unyielding force. Her pussy was a sopping mess, lips puffy and red, clinging to his veined length as it pistoned in and out. Climax after climax tore through her, each one more intense, until her vision blurred and her body went limp.
Finally, with a guttural roar, Allen buried himself to the hilt one last time, his cock pulsing as he unleashed torrent after torrent of hot cum directly into her womb. The flood was immense, overflowing her stretched channel, mixing with her own creamy yogurt-like fluids that poured out in a steady stream, cascading like a river from her pussy down her trembling thighs, pooling on the lab floor in sticky puddles. Rebecca's eyes fluttered shut, her consciousness slipping away in the overwhelming bliss.
Allen eased out slowly, watching his seed leak from her abused hole, but he stayed close, cradling her unconscious form against him, the lab silent save for their heavy breathing and the faint hum of equipment.
