Sophie groaned, down on all fours with a guy in front of her and behind her. Her bare knees scraped against the rough ground, just bare tarmac down one of the alleyways, but she didn't care. It was unfortunate to get herself roughed up but it was, in that sense, part of the job.

"Gnnngghhh..."

With her long, black hair, Sophie was a sight to be seen, though it was her overly large breasts that commanded the most attention. Some would have kindly said she was voluptuous, although even Sophie would have said she was merely big-breasted, even if that wasn't the most diplomatic way of putting it.

She moaned lustfully around the cock in her mouth, her crop top cutting so low over her breasts that most of them seemed to be spilling out. Even then, her clothing barely kept her breasts in check.

She was getting a good slice of cash for that one and she grinned, heat in her cheeks, a flush crawling down her neck as her black hair bounced around her face, tickling her shoulders. Her pussy squeezed around the man driving into her, though he wasn't all that concerned about the intricacies of what he was doing, not as his hips slapped rampantly off her ass with every crude thrust.

"Damn, look at this whore," he hissed through his teeth, words barely audible through his grunts. "Takes cock like a pro."

"Idiot, shut up, she's a hooker. Of course she does."

Sophie didn't take offence to that, though she trembled as the guy jabbed his dick inside her to an almost uncomfortable degree.

Strange, she thought. I didn't think his cock was that big.

Their dicks very much had not been, yet Sophie's mouth gaped wider and wider, drooling around the shaft suddenly forcing her lips apart. She squealed, the muffled sound lost around his prick, as he rammed in more roughly, driving the head of his shaft right up into the back of her throat.

Despite her skills and experience, Sophie gagged, convulsing as she was used, something twisting out of control. Yet she was not to know that the insidious flow of the virus had floated down into the alleyway, slinking back and forth through the air in a muted purple haze as if it was a serpent preparing itself to strike.

The virus had separated, not seeking a single city but infiltrating many. Sophie was just unfortunate that the virus infected her partners, forcing her body to strain around them and stretch as they hammered into her.

The men had cut dark, not all that striking figures in the night: nothing unusual from her normal clientele. If she thought back, she may have thought they'd had dark hair, but it was tricky to tell when she serviced so many; Sophie usually only remembered specific details if there was something that she thought was odd about a situation. In those cases, her memory saved her.

"Unff... Nnngghhh..."

The man to her back groaned as he leaned over her thick buttocks, the roundness of her bubble butt bouncing off his crotch with every stroke. His shaft swelled inside her, forcing her pussy to accommodate him, and her eyes watered, trying to shake her head and pull back as the guy ramming into her throat grabbed her hair.

They couldn't help it, however, even if their feelings on the matter were not important in the slightest. They were just mutations of the virus in that moment, their skin rippling and pulsing. Tentacles slithered under their skin, showing through their flesh as if their intestines had come to life and were twisting back and forth, laying waste to their bodies as they'd known them.

If they had not inhaled so much of the virus, perhaps it would have taken longer for them to transformation but, as it was, their bodies exploded in a wet, splattering writhe of tentacle cocks. Their skin did not peel apart stickily like it had for others who had suffered similar fates, but erupted.

They bellowed, tentacles lashing up from their mouths, tongues splitting into multiple tentacle cocks too, their limbs melting and whipping back and forth into a mass of tentacles too. As quickly as she'd agreed to service them, the night took its darkest turn yet, Sophie crying out and twisting as masses of tentacles swarmed her.

She screamed, that cock suddenly free of her mouth, though Sophie was not to know their dicks had split and were in the process of mutating into more tentacle cocks still. With a slick, blue-grey sheen to their skin, they were not of an earthly origin, even as a mutagen, slithering all over her, wrapping up her limbs, so she was forced to hold her position on all fours.

"Agh! No, what the fuck? Let me go -- let me go!"

Tentacle cocks curled around her even as she wrenched against them, fear locking its icy fingers into her heart. Yet she could not help, even then, but shudder away from the slimy, cummy wetness of them, twisting her head even as one smacked against her.

"I don't know what kind of freaky shit this is," she hissed, finding a reserve of strength she hadn't known she had. "Ugh... No... All of you get off me! I'm not..."

Yet Sophie huffed and panted, curling away from a tentacle dick as it probed at her mouth, the blue-grey length undulating like a snake as if it was surveying her. Her heart skipped a beat as it reared back, just like that serpent readying itself to strike, and she screamed, failing to realise that attracting attention, even then, would not end well for her.

"Agh-mmmph!"

She screamed around a tentacle cock filling her mouth, eyes bulging and strained. For it had taken its chance when it saw it, shoving its way in past her pretty, full lips even as they closed around it. Sophie screamed muted, her frustrated cries blocked by the tentacle dick in her mouth, though it pounded her mouth and throat just like a cock, shoving its way brutally right past her gag reflex as if it had never had any meaning there in the first place.

Well, Sophie had been good at things like that, to be fair. Her eyes rolled into the back of her head as she shoved at the twisting mass of tentacles before her but was forced to drop back to the ground again, just to steady herself. Holding fast her position, even with the gross tentacles winding around her as if in a horrific kind of bondage, was all Sophie had left: the tiniest scrap of autonomy.

She tried to grab at the tentacles but her hands slid uselessly off them as her stomach lurched and bile threatened to rise in the back of her throat. Slickness from the tentacle cocks drooled all over her, though it didn't have the consistency of semen, something stickier and clingier dripping all over her body.

Although Sophie had been wearing a short, red skirt beforehand that framed her ass nicely, there was no need for it to remain in place. The tentacles shoved it up even higher around her hips, revealing her bare ass, a cock ramming into her ass while another claimed her pussy. There was no telling just where they had erupted from the mass of tentacles that her clients had once been, but that ceased to matter to Sophie in the moment.

She clawed at the ground, arching her back even as her body quivered, straining to scramble away. Yet the tentacles curled around her lips, drooling that sticky essence, even sliding through her hair and curling around her neck to hold her in place. She moaned, though it was a blessing to her she wasn't able to see how monstrous she looked already.

One fed its way down her throat, cutting off her ability to breathe, and she hacked around it, chest heaving, breasts jiggling in the weak hold of her shirt. Her eyes streamed and she blinked rapidly, though that didn't help clear her vision as much as she'd wanted it to. Even her gag reflex kicked in, as if something had affected her, changing what had been Sophie's norm for so long already. She couldn't let it overwhelm her, she couldn't! It must have been a drug, she thought, yes, something like that. Maybe one of the guys had drugged her?

Caught up in the moment as she was, it was impossible for Sophie to say either way as her body shuddered in overstimulation. Her pussy squeezed inadvertently around the tentacle cock cramming into her, though the skin was smooth, reducing friction even with how thick it was inside her. It bloated out as if swelling from the inside out and she let out a groan without even thinking about what she was doing, eyes closed against the monstrosity.

It's just a dream, just a dream, she told herself inwardly, even as tears rolled down her cheeks, sliding around the sticky, lewd tracks of muck the tentacles left on her. I'm going to wake up tomorrow and be worse for wear, but I'm going to be okay. Everything's going to be okay, I'm going to be okay.

Yet there was no way for Sophie to know that, not as the tentacle cocks squeezed her breasts, worming their way insistently up under her shirt to get at her tits. They had little finesse, not ripping her shirt for the time being, but squirmed wetly, wiggling out over the neckline of her shirt. She shuddered in revulsion, though there was no way for her mind to take her away from the horror of the moment, not when she was so bound into it as she was.

No... Fuck no! This can't be happening!

Her thoughts screamed while her reality raced on without her consent.

It was not like any sex she'd ever had before and Sophie was quite experienced. She tried to howl around the cock in her mouth, though it twisted and pulsed with a mind of its own, almost as if every tentacle was an individual creature. She ducked her head so her chin almost brushed the ground and she lurched a couple of feet towards the wall and her bag, though it was not as if it was going to do her any good at all.

The tentacles slammed into her, making a mockery out of her body, her buttocks rippling as tentacles pressed into her soft flesh, manipulating her for their will. A rumbling gurgle heralded something of an orgasm, though it was different to what the men would have ejaculated, if they had even been able to do so. Their minds were still there, overcome with endless bliss, yet they could not control the tentacle cocks.

They didn't matter, Sophie's eyes watery as she gulped viciously, a large bulge showing through her throat as she fought with all her might to contain what her body was being forced through. Her lungs screamed, pain lancing through her body as she strained for breath, but it was not as if she was going to even need air for all that much longer anyway.

The tentacles closed around her, trembling as they filled her with semen, her lips parted wide as litre after litre of slick seed poured straight down her throat. Her belly plumped up from her womb and her stomach being inflated with seed, rendering her soft and squashy around the midsection. Yet, in that instance, it was not a smooth bloat, her belly still squishing in as she stumbled against the ground, losing the grip she had with her hands and bouncing off her tits.

"Nnngghhh..."

Sophie groaned, fighting to understand what was happening to her. She was not to know that she was one of few who'd transformed and kept their own mind for longer -- though the virus was mutating, even then. It was all part of the process and she was merely one little nuance in something far larger than even she would become.

Her belly sloshed, so heavy and full with cum, her mind spinning. What was happening to her? How could all that fit inside her? It didn't make sense, not in he slightest, though she rolled her hips back, fighting even in a small way to alleviate some of the strain on her body. Drooling around the cock bulging out through her throat, stretching her jaws so far that it had to be beyond any limit she'd thought was in place on her body, her eyelashes fluttered.

Hold on... She told herself dimly, even though she could not have possibly known all was to be well in any way. You can do this. You're going...to be okay.

Her body squelched lewdly around the tentacle cocks, yet that line of pain and pleasure had long since blurred, two tentacles grinding together into her pussy all at once. As they slickened down with the tentacle beasts' orgasms, they pushed deeper and deeper, dragging the nest of tentacles behind them along too. One tentacle pulled out of her ass as they forcibly shoved their way inside her body, although the relief that came from not having her anal ring stretched forcibly wide was fleeting and short-lived.

"Nnngghhhh... Agh!"

She groaned around the tentacles as the softening mass fed itself into her mouth, straining her throat as she gulped them all down, acting without thinking. Revulsion heaved in her stomach as her pussy took in the second man-monster -- whatever it was he had ended up being. Slime-like cum drooled from her mouth as she heaved, the last tentacles slurping up into her mouth and winding around her tongue as they dragged their own way down inside her.

"Agh!"

She gasped and swiped anxiously at her mouth with both hands, trying to rub the cum and slime off her, whatever grime had come into play there. Her eyes streamed with tears, her body releasing tension in whatever manner it thought best, though the sweet bliss of air flowing more easily into her lungs again was, at the very least, a blessing.

Temporary, but a blessing all the same.

They didn't end up in her stomach though, even if her body bloated out as the second monster fully merged with her via her pussy. She grabbed at herself, sitting on and scrambling back, though there was no longer anything for her to flee from.

"Agh... Huff... What the..."

Sophie rubbed the back of her hand across her face, skin still slick with the monsters' lubrication, heart pounding in a dull roar against her eardrums.

"Those... Those things... They're...inside me!"

She grabbed at her flesh and pushed her stomach down, though all that did was force some of the semen back out of her pussy, squelching crudely and marking her inner thighs. Heaving a sob, she staggered half upright, hunched over and bow-legged. Thankfully, Sophie still had her heels on, but that didn't help her much as she rubbed her throat, aching furiously from the vicious face-fuck she'd been forced to endure.

She understood, however, part of what was happening to her and that was just why it seized her heart with fear in an ice-cold grip. The mutations faced by other cities were becoming increasingly better documents through crazy videos and even some sound recordings -- she didn't know which was worse in the recounting -- and there was no question as to what was happening. She'd just never thought it would spread to her city!

"Unff... I gotta... Gotta get home..." She heaved, pulling her skirt back down around her upper thighs, affording herself the modicum of modesty. "I've got to...stop this...happening to me."

But what could she do about it? She'd felt what had happened to those guys! Sophie, however, didn't have time to feel sorry for them in the slightest as she staggered, her mind fixed solely on her apartment.

That, however, was going to be a tall order as the virus had not infected only the men that time. It was already spreading through the city, tentacle monsters roaming, some still walking and others slithering in a crawling mass of tentacle cocks across the ground like a horrific organism from a sci-fi movie.

She had to try though, for she didn't want to give up so easily, not as she scurried out of the alleyway and ducked straight across the street into another alleyway, that one a bit wider, going behind some restaurants. Her stomach churned uncomfortably and she felt a lot heavier than she had before, though the squashy bloat was not all that bad. It was not so hefty that it should have greatly affected her way of moving, after all, despite the laborious pull and sway of it. Her mind knew it should have affected her centre of balance, yet Sophie didn't have it in her enough to care for any difficulty like that.

She just had to get home and everything would be okay. At least, that was all she told herself.

"Unff... Okay, on to the next bit, I can do this. I can definitely do this."

She smiled tightly, though her hair clung wetly to the back of her neck where the tentacles had partly coated her in sticky semen. Her state was the least of it as she reeled from another tentacle monster, that one halfway up a building as its tentacles punched holes in a glass window, presumably to capture the occupants of the apartment.

She didn't want to be caught by anything like that and she set her jaw resolutely, feeling the tension ache back up into her skull. It was better than the alternative of being caught and fucked, for Sophie still held on to a bit of hope that she could get out of the horror of the situation she'd been forced into.

For no one could have possibly chosen it for themselves, after all, and she ducked under shop awnings in the shopping area, though it was more adult-orientated services that were to be found there. The sex shops and nightclubs erupted with screams, though it was late enough that even those were dwindling in clientele.

Sophie didn't want to consider the notion that none of them could escape the tenacious infection, sneaking into cracks in walls and filtering through vents to spread its influence. The moment she lost hope was the moment she gave up entirely.

She wasn't that kind of woman.

Every step came with a great effort of will as she dodged a monster stumbling from another alleyway, tentacles erupting from its mouth even as the rest of its flesh bubbled with seemingly more. She didn't want to think about the specifics of that, not even as a woman suddenly fell to the ground in the middle of the street, groaning aloud as her tits suddenly expanded.

Sophie could not help but pause for a moment, watching her as her breasts ballooned out, straining against her shirt and tearing through, though that could have been due to the roughness of the road under her. Or maybe she'd been wearing something sheer to go out to the clubs, not needing to cover up all that much.

Sophie would never know as the woman's breasts swelled to hyper proportions, easily larger than her entire body, leaving the rest of her oddly "stuck" to them. She couldn't hang around as she made her way further down the street and ducked into a side avenue that was a little quieter, her breath raking down her windpipe with every gulp of air.

"This is crazy," she muttered to herself. "This is all so fucking crazy... How is this even happening? If I'd be home tonight, none of this would have happened... To me, at least!"

For all she could hope for was to escape the transformations herself, choosing to ignore the inevitability of it all. Her body gurgled, though there was no true origin for it as she paused, allowing a couple of tentacle beasts (she thought they still had limbs but couldn't be sure in the dimness of the avenue) to pass in front of her. Their tentacles writhed and twisted together in a lewd, wet slop, the damp sounds slapping into one another while they clearly found holes to penetrate.

She had to jump over the wash of cum they left in their wake, startling as a man slammed into a window from the inside, a mass of tentacles erupting from a rubber-like slit in his chest. It was fucked up and it was insane -- but there wasn't anything she could do to help any of them.

A small parking garage offered her solace and she cut through there, hoping it would shorten her laboured half-walk half-run back to her apartment enough that she could get home in one piece. Yet pressure built up inside her, as if something was expanding inside her without affecting the tension of her skin as yet, and she shuffled more and more heavily as she came out of the parking garage.
