Contagion

Dr. March strode through the ward, pushing the trolley forward. Normally she’d get someone else to do this, but this was urgent. She slammed through doors, her labcoat flowing, looking down fearfully at the body below her. Eventually, she made it into a quiet ward. She had to keep this on the down-low.

Removing the sheet, which wasn’t that necessary, given the two massive mounds that poked up into the air, she saw Bea, her best friend, lying, slowly breathing, with two frankly enormous breasts jutting up about twelve inches from her chest. Her hospital gown could barely take the load. Bea opened her eyes, blearily.

“…what’s going on, Sal?”

She couldn’t tell her. Bea had apparently overdosed on some experimental breast growth treatment, and her tits had been swelling ever since. Sally knew she shouldn’t’ve taken her to hospital, but she didn’t know where else to go. Luckily it was early morning, and there weren’t many people around.

“I’m gonna run some tests, Bea” said Sally, taking a sample of Bea’s blood.

“It feels so good, Sal” Bea moaned, sleepily clutching for a huge nipple.

Sally felt a pain in her chest. She’d worn that tiny bra again – idiot! She was very slim and tall, with no breasts to speak of, but even so, she had a bra that was too small even for her that she wore when she couldn’t be arsed to do the washing. Bad timing. She felt under her white shirt, which was luckily quite a baggy one, and discovered her bra was unexpectedly full. Strange. Suddenly, her blood ran cold.

As her hand rested on her breast, she could feel it swell outwards, growing against the bra.

“This is…infectious?”, she thought to herself. What the fuck! She shook Bea, trying to ask her, but she’d gone back to sleep, her huge breasts wobbling and still growing directly upwards. “I don’t wanna look like that!”, thought Sally, though the thought of her breasts being bigger was actually pretty appealing. Suddenly, she realised – if she was infected, who else would be?!

She had to get this blood tested ASAP.

On the way to the blood labs, she couldn’t help but notice everyone seemed…bigger. Doctors were wobbling a bit in the corridors, and female nurses’ uniforms looked a little…tight. As for her own, her bra was really digging into her. She slipped off to the side into a bathroom to remove it.

She sat down in a stall, and closed the door. She hung up her labcoat and reached round the back of her shirt to take off her bra. It was really digging into her back, leaving marks in the flesh. She went to remove it, but it suddenly pinged off, and her swollen breasts bulged outwards! Sally couldn’t believe it. She looked under her shirt. She always had very small breasts, and now they swelled two inches out in front of her. They were really firm, too, with big nipples. She felt an almost uncontrollable urge to rub them, but resisted. She buttoned her shirt back up, noting her tits fit a lot less well into it than before, but that it was still reasonably roomy, and went to put on her labcoat.

She heard a noise at the bathroom door, and a male and female voice as a couple burst in. She could hear the stretching of fabric and the grunts of two very aroused people. Forgetting the swelling in her chest for a moment, she put her eye to the crack in the door, and saw a large breasted nurse in scrubs and a male doctor looking at each other with lust in their eyes.

“Look how big they are!”, the nurse cried.

The man sshhed her, until she removed her top, and the sight caused him to close his mouth. Sally nearly gasped herself. The nurse had a big bra on, but her tits had bulged almost completely over the top, and were still swelling outwards.

“God I want to fuck them”, said the doctor, out of nowhere.

They were both momentarily taken aback by what was said, but in seconds the two people were pulling off their clothes and on the floor, the doctor putting his dick between the nurses still growing breasts. Sally didn’t want to watch, but she found herself growing increasingly horny at the spectacle. Also, the tremendous tit-fuck was occurring right in front of the only exit to the bathroom, so unless she wanted to interrupt – which would’ve been really awkward – she didn’t have much choice.

As nurse’s breasts swelled and bulged (she’s outgrown her bra long ago) and the doctor rammed his big cock between them, Sally suddenly remembered her own chest. Looking down, she was shocked at how much it had grown in the past few minutes. Her breasts were now pushing forwards against the fabric of her shirt, and bulging to the side. Without a bra to contain them, they were pulling the fabric between the buttons apart, the buttons themselves having to do quite a lot of work holding her swelling tits in. She was getting so horny. Her breasts swelled a good four inches straight out now. She had to get out of here or fuck someone or both very soon.

Looking back out, she saw the doctor’s big cock harden as he came between the nurse’s magnificent tits, leaving a big trail of cum between them and on her chin. He licked it off her, and she smiled. They kissed, and he helped her up. She just about squeezed back into her scrubs, but it was abundantly clear she had massive zeppelins underneath, which were stretching and bulging against the formerly loose fabric. How was she going to function with such huge tits? The top half of her scrubs also rode up to just above her midriff, exposing her flat belly. She noticed this, with a smile.

“We should really do that again”, said the doctor.

“Oh yes.” replied the nurse. “Also – and I’m aware you’re the expert here – but your dick is definitely bigger.”

The doctor looked down. “Really? It was already so huge, I couldn’t tell.”

The nurse laughed, punched the doctor in the arm, something that sent her tits jiggling, and together they left the bathroom.

Sally breathed a sigh of relief, and felt a sting on her chin. Looking down, her top button had pinged off and fired upwards. In the last exchange, her tits had really swollen, now sticking about six inches straight out in front of her. Her shirt was starting to struggle, and with the top button removed, her cleavage was clearer than ever. It looked gorgeous, but staring at it was starting to make her wet again, so she folded her labcoat over her still swelling breasts, and bounced out of the bathroom.

Back in the corridor, she noticed some very strained clothing. Maybe it was the fact that she was incredibly horny, but everywhere she looked appeared to be big, swollen breasts bulging out of clothes, or hard dicks straining in tight trousers. “Whatever this thing is, it’s really getting to me”, she thought, as another button burst from her top. Her large breasts were still swelling and bulging outwards from her struggling top, and only a couple of buttons remained before they’d be out for all to see. Taking advantage of the newly-found space, her tits spread into place, putting new strain on the remaining buttons. Her cleavage was seven inches, her breasts even bigger than that. They wobbled out to the side, pulling apart the fabric between her buttons. She knew her shirt wouldn’t last much longer.

Walking along, she could feel, to her surprise, her ass growing too. She was wearing a fairly tight black skirt, but it was getting tighter by the second. This clearly wasn’t the main target of the…thing going round, but her ass was getting bigger and rounder by the second, and was making walking without sashaying very difficult. She started to see some of the male nurses’ heads begin to turn as she strode down the corridors, her big tits bouncing and her wide ass swelling. There were big hard cocks everywhere. God she needed to fuck.

She entered the blood lab, and saw Jacob. She’s always had a bit of a crush on him, and today was no exception. She could see from the straining in his trousers that he’d been infected too. He raised his eyebrows as Sally wobbled in.

“You look a little…bloated.” he noted.

Sally felt a tear as her skirt began to rip down the side, and another button popped off, allowing her still growing breasts to swell forwards, putting massive strain on the last one. Her chest surged nine inches in front of her now, and her breasts were hugely round and pert. She was ludicrously horny.

“Jacob, I…need this…look, can you do me a favour, I really can’t concentrate.”

Jacob said nothing, but slowly walked behind her, kissing her on the neck. She could feel his massive cock erect against her ass, which was growing slowing into it, her black skirt ripping further. He moved his hands up her body, ending up on her massively swollen mounds, which just at that moment burst forth from her shirt, which lay hanging to the side of her glorious body. Her breasts wobbled out to the side, and were truly huge now, around ten inches straight out in front of her. From his position behind, Jacob could barely reach the nipples.

“Oh god, fuck me with your growing cock”, begged Sally.

As if in response, Sally’s ass grew bigger again, ripping out of the black skirt. Her underwear had almost been absorbed by her huge ass, but Jacob ripped it off and slowly eased his growing dick into her incredibly wet, but tight cunt.

This pleasure was what Sally had been waiting for – it shot through her whole body, causing her to shake. Jacob pushed her against a workbench, and thrust his huge cock into her, again and again. She could feel it growing inside her tight cunt, and it felt amazing, and as breasts and ass swelled outwards. Leaning down on the bench, she could feel herself rising as her huge tits bulged in front of her. They were pressed down onto the bench, spreading out as far as they could, but as they grew and grew she was lifted upwards, into the perfect angle for Jacob’s cock. He grabbed her hair roughly as he thrust his swollen cock in her again and again, as if he was pumping her up.

Sally grew and grew, her breasts and ass swelling and bulging as they fucked, until Jacob could barely see his dick, just two huge cheeks swelling over her cock. This sight was too much for him, and he came tremendously hard inside Sally, his enormous cock sliding out just in time – it really was getting too big to fit inside her cunt, even as wet as it was.

They fell to the floor, panting. Finally, Sally could think clearly, the fog of arousal temporarily lifted. As her breasts and ass swelled again (she could barely sit up straight by now), she could feel it return, so she moved quickly, or as quickly as her massive, bouncy figure would allow.

Suddenly, she remembered why she was here – the blood sample! She wobbled to the table, surprised at how heavy her new tits were, her legs slippery from both her and Jacob’s cum, and grabbed the vial. She jiggled over to the microscope, still swelling, and leant down to examine it.

Picking the microscope from the floor, she reminded herself that she could no longer really stand face-on to things she wanted to use – there was a huge pair of twelve inch watermelons in the way. Turning to the side, letting her huge tits quiver next to the bench, she examined the blood. Straight away, her post-coital clarity identified a rare combination of factors which she knew to the be the cause of the expansion.

She ran to the lab to get it synthesised. Inside the lab, Jacob grabbed her arm. She looked down to see his cock, rock hard again, and even bigger than before.

“Are you really going to stop this?” he said.

She turned to the corridor, seeing nurses with tremendous breasts wobbling down the corridor, blind with lust. She saw doctors burst out of their shirts, placing janitor’s massive dicks between their humongous breasts.

She produced a vial of green liquid, freshly synthesised, glowing and pulsing against her still slowly swelling tits. She pressed her enormous chest into Jacob’s body, squeezing her titanic breasts up against him.

“Stop it? Hell no. I want to control it.”

Jacob smiled, and she could feel his erection press into her cunt.

“Now,”, said Sally, reaching down. “Let’s see that big cock of yours.”
