"Harder!"

Jay obliges Dani's request by doubling the speed at which he pumps his newly enlarged cock into her tight slit making her also recently enlarged tits bounce around as he slammed into her from behind. Dani's body shudders and Jay pulls out as she collapses forward in the throes of orgasm. His nearly foot long cock twitches and a stream of cum drips out onto her upturned ass and down the back of her left leg. Rubbing the tip in the pool of goo, the goo that had started it all, he then dips the strawberry sized tip of his monster cock into her tight asshole. She squirms and moans with anticipation.

"Yeah! Fuck my ass! Fuck it with your big hard cock!"

Eager to please Jay shoves himself in up to the hilt. Never in their three years of dating had they done it this way. It was a tight fit and Jay begins to buck almost immediately, the feeling of her tight hole on the base his giant pole a strong counter point to the velvet softness around the tip.

"I'm going to cum!" He groans.

She moans in return. "Oh please do! Pump more of that magic cum inside me!"

Jay feels his body relax as his apricot sized balls contract and pump their load into his cock. The first pulse is small and fills her ass just past his head. The second pulse forces a wave of cum out of her hole around his shaft; a white river flowing down over her slit, down her belly, and into the valley of cleavage below. The third pulse hits with such volume that the wave pushes him out and flows over his cock, balls, and the insides of his thighs. A fourth pulse building in his cock, he pushes her over onto her side. Rubbing his well lubed shaft with both hands he finally sprays a massive load that paints her torso, face and long red hair white; along with the floor, the couch and the wall the couch rested against. He is stuck that way, his back arched and his hands working furiously, for two more equally huge sprays. When he finally collapses, his balls spent, Dani is already sound asleep, likely dreaming of an even more sexy body.

In what feels like hours later Jay rolls onto his back to stare at the ceiling, his mind clear of the burning need to fuck. It was unquestionable that something inside him had changed yesterday. He glances at the clock and seven am stares back at him. It'd been nearly a day since he'd likely been changed. How far have things gone? How much further will things go? Were either he or Dani even human anymore?

Unable to just lay still anymore Jay stands and stretches. He is keenly aware of his further enlarged penis and balls rubbing against his legs, the re-uncircumcised foreskin tickling the skin just above his knee. Deciding to take stock of how far the changes had progressed he walks to bathroom to stand before the full length mirror on the door. Jay notices that aside from the overall more masculine look of his frame nothing else of his body seem to have been affected to the same extent as the plum sized balls that were nested behind a penis that would rival a horse's.

Thinking about it, he was already sure of a correlation between the growth and his cum, so the result made sense. Dani on the other hand, had been coated inside and out with as much cum as she could milk out of his balls. Walking back to the room, Jay sadly admits to himself that he didn't really try to stop her after he realized what was happening. Even if at the time his mind had only the word fuck in it, the inherent dangers should have held him fast.

He steps into the room and gazes at her almost amazonian form. Since her first accidental cum bath she had grown three inches or more in height, though it was likely that the second and third ones didn't hurt. Still asleep, she was resting her face on her huge and still pulsing breasts. Standing there Jay guesses they are roughly the twice the size of soccer balls and wonders if she'll be able to walk when she awakens. Though considering the other physiological changes, like that her ass, mouth and vagina could still accommodate his horse cock, he guessed the alterations to her body were uniform in their pursuits.

How had it turned out like this? Jay asks himself silently. Yesterday was such a nice day...

Though Jay was inside at work. Well, it wasn't really a job, more like an obligation. He was only a semester from his degree in Biology and the internship at a local medical research firm fulfilled one of the remaining requirements.

"-nd zo, zis treatment vill radically alter the vay ve fight AIDS! The virusez make up vill rewrite the HIV in the vhite blood cellz and encourage the body to make new-"

The lecture about the trial bored Jay, whatever it was they were testing, the process remained the same. Inject infected cells and then watch them in a scope for a few hours. He longingly stared off into the distance, his fingers rolling a pencil back and forth, wishing the day was already over. He thought of his anniversary date with Dani later that night. Suddenly realizing he'd forgotten to make reservations, he began to tap his foot impatiently until the man in front stopped talking and stepped back from the podium. As everyone else clapped, Jay had dashed out the side door of the auditorium and punched in the number for Dani's favorite restaurant.

Satisfied after a few minutes of haggling with the hostess on the other end on the line he flipped the phone closed and dashed of towards the the lab where they'd do the trial. As he rounded the corner of the hall he collided with someone. A rain of hermetically sealed bags showered Jay and the other person, one bouncing painfully off of his head.

"Ow..." After rubbing his head for a second, Jay stood and offered his hand to the stout man he had bumped into. Jay recognized him as Dr. Finkworth one of the head researchers at the institute.

"I'm sorry about that, sir" Jay apologized profusely.

The stout man stroked his long bushy mustache before speaking. "It is okay young man. You're just in a hurry for science. I wish all youngsters had your drive." He spoke with a thick British accent and his mustache twitched and fluttered whenever he spoke, because of this Jay sometimes had a hard time following what the old scientist was saying.

"Oh, right." Jay said, feeling a bit guilty as he and the doctor stooped to pick up the packets. "Are these the test instruments?" he asked turning one package over in his hand.

"They are!" The old doctor waved one of the packets absently in his excitement. "These are the hope of the human race's attempt to cure a conventionally incurable disease. If the research here is successful it means bio-engineering could become the answer to all of humanities ills."

The statement made Jay more ashamed. To think he thought of this place as just a hurdle to jump over. The work he was doing here could save his or Dani's life one day. His shame following him, the pair carried the stack of packages to the lab together and distributed them to the other thirteen grad students.

"You all know the drill, open the packet, open a dish, dispense the serum into dish and set it under your scopes. This will be a twenty minute trial to test the strength of initial exposure. There are three dishes to test so it will take an hour. Please seal and label your dishes after each test, we'll be working with them tonight to observe the affects after eight hours."

Jay tore the seal on his packet and pulled out the bag that contained the dishes. Then, he reached in and pulled out the vials that contained the serum. He screwed a tip onto the first vial and cracked the seal on the first dish. He was about to drip in the serum when someone bumped into him from behind.

"Fire! There's a fire!"

Turning Jay was met with the spectacle of a scope on fire. The stupid student grabbed an extinguisher and sprayed the scope until the can was empty, long after the fire had gone out.

Jay shook his head and turned back to his work. Almost instantly he realized something was amiss. He didn't have the vial in his hands but it wasn't on the counter either. He looked back in the bag and then stood up, thinking the vial may have fallen into his lap in the chaos. When the plastic vial fell out of his lap, Jay felt a relief that was short lived as he stooped to pick it up. His fingers stopping inches shy of touching it he realized the pink fluid that had been inside before was almost gone!

He panicked at first and then the open dish on the counter pulled at his attention. He tried to think if he had already administered the serum. Sure that he had, for where else would the serum have gone, he grabbed the vial and took his seat again. With a the chaos it'd been twenty minutes already so he sealed the first dish up and started the second one.

A little under an hour later Jay was on his way out and in that time his pants had grown uncomfortably tight and warm. He'd pushed it out of his head during the trial as an effect of sitting for an hour, but as he passed Dr. Finkworth on the way his doubts about what had happened to the vial's contents crossed his mind again.

"Sir, what would happen to someone if the were exposed to the serum in it's current state?"

The doctor crossed his arms and stroked his mustache. "Hmm. That is a fair question. The serum contains an intelligent viral couplet so, they would probably go about their programming."

"But what if that person wasn't sick?"

"I don't really know, we had not reached that point in the testing yet. Seeing as we're still affecting our research on just cells alone. I would believe the virus would, having nothing to attack, go into remission and eventually pass out of the person's system. But, I have no idea." The old British man raised an eyebrow and fixed Jay with a questioning glance. "Why do you ask?"

"Oh, no reason. Just...being scientific." Jay hoped the grin he flashed was reassuring.

The doctor laughed and clapped Jay on his back. "That's the spirit, young man! Just keep those kinds of thoughts in your head and you'll be a fine person; scientist or not!"

Jay nodded cheerfully, a sick feeling in his gut. Thanking the doctor for his time the grad student hustled home to grab a shower before he went over to pick up Dani from the airport. The drive home was uneventful, though he was a bit uncomfortable with the weight of what might have happened pressing down on him. To top it off his balls felt like they were being crushed even with his legs spread.

Eventually, he convinced himself it all had to be anticipation of the coming night. Dani, like Jay, was a grad student. Unlike Jay, she was a journalism major and her summer internship had her off all over the place. The magazine had hired her because they covered competitive lacrosse, something Dani did. It would be two weeks tonight since she went off to nationals and as he pulled into his spot in the parking lot he was completely sure his swelling was due to excitement.

He got to the door and as he turned the key he found the door unlocked. Dani had a key to the apartment, perhaps she had gotten home early and let herself in. Stepping inside Jay tossed his bag on the couch.

"Dani? You here?"

Dani's voice responded from the far room. "In here Jay."

Jay walked back to the room but saw no one in it. "Dani?"

"Right here." her voice whispered in his ear as fuzzy arms wrapped around him. "I've missed you so much. Denver was boring, we lost in the third round." Dani pouted as she pulled Jay down onto the bed. Though wrapped in a blanket, she certainly was a sight for sore eyes.

Jay ran his fingers down through her short dark red hair and then along her cheek. "I missed you too."

Her eyes softened and she pursed her lips. Jay took her offer and leaned into her. It was wonderful to feel her lips again, like tasting ice cream in a desert. Absently he dipped his hand into the blanket and ran it along the smooth skin of her neck and shoulder. After a few seconds they broke apart.

"I think someone else missed me more." Dani remarked as she rubbed the bulge throbbing in his pants. Jay felt his face get warm. Dani caught his coloring and laughed sweetly, pecking him on the cheek. "I don't blame you hun. I'm sure you missed me most out of the two of you."

She ran her hand from his bulge to his chest. "Should we have an appetizer before dinner?" she asked with a slightly evil grin.

A moment of doubt crossed Jay's mind. A moment of hesitation that Dani took as agreement.

She nipped his neck as unwrapped herself from the blanket. Jay had somewhat forgotten the way she looked after being apart and piled under work. Seeing her in nothing but her panties as she crawled down him reminded him and then some. Athletic by occupation, her frame was well toned. Even so, she carried a just enough extra, giving her curves in all the right places.

Dani undid his pants and slid his modest cock free. She pulled the band of his boxers down further and over his balls. A gasp escaped Dani's lips as his balls fell free of the confining fabric. Curiosity over took him and leaned up to look. They were huge! It looked like a pair of walnuts were crammed in place of his original ones.

"My my..." Dani mused as she teased the base of his cock with her tongue. His swollen balls twitched at the stimulation. Dani bent further and nipped at the tight skin of his sac and it twitched again, more forcefully. Flicking her tongue over the taught surface sent shivers through Jay. In the years of dating Dani had given him hundreds of blowjobs but for some reason this time out of this world. Up his shaft her tongue crawled as a soft hand cupped his balls, her thumb softly massaging his swollen testicles. Now her mouth teased the tip of his twitching cock. The soft nips that always drove him crazy were paralyzing and he could only lay there was she slid her moist lips down his cock. As she wrapped her tongue around his cock he felt her tease his asshole with her middle finger. Where she picked up the habit he wasn't sure, but it made him so hard when she did it.

Dani slowly began to pump his cock and along with the attentions from her hands, she quickly had Jay seeing stars. His breathing caught as his balls contracted and it felt, to his over stimulated and somewhat stressed mind, that all of time and space stopped for the moment. With a massive throb he shot the largest load he had ever managed down her throat. She jumped back sputtering and gagging as another wave exploded out of his cock and covered her face, chest, arms, and fair bit of the bed as well in white sticky gunk.

After a moment of tense silence, Jay tried to say anything but was at a loss for words as he sank into the plush mattress. Dani hopped up off of the bed, her expression mixed.

"Shower?" her voice was shaky as she extended a cum soaked hand. Jay shook his head weakly, his body too heavy to move. Dani shrugged and disappeared into the hall. Before she had even stepped out of sight Jay's mind was burning as it tried to figure out what had just happened. His balls didn't hurt any more, in fact, they felt emptier than ever. Deciding that the whole thing really was two weeks of celibacy coming to an end, Jay put it out of his mind and got up to catch the shower before Dani tured it off.

Half an hour later the couple was in Jay's car. The drive over was filled with small talk about the pair's two week break. Dani's team had gone to the third round of nationals but, they lost to NC State. Caught up in the moment, she gave him the blow by blow of the three rounds, her face bright with excitement. Behind the enthused conversation though, Jay caught an undertone of want as Dani repeatedly paused on just the right words. He could feel himself getting hard and it wasn't just the pauses in Dani's story. Something about the air in the car was making his thoughts derail to the gutter and he would frequently stop in mid-sentence.

They got to the restaurant and touched for the first time since the cum bath earlier. The feel of Dani's hand in his own made Jay stiffen further. Out of the corner of his eye he could have sworn her handfuls worth of tit were wobbling more than usual. He blinked hard and tried to think of cute kittens or something else aside from bending Dani over the railing and fucking her right there. Thankfully they were a few minutes early to Jay's reservation and the pair was soon sequestered in the corner booth of a dim room with a heavy oak table between them.

The waiter took their drink orders and they put in for some bruschetta, while they figured out what to eat. Jay made a point to look everywhere but right at Dani's chest as they talked about the merits of their meal choices. Thankfully, the menu covered for him when he made eye contact.

The waiter's return with the drinks and bread broke up the tension inside both Jay's mind and his pants. Over and over his eyes had lingered over Dani's lips, remembered the feeling of them on his cock. When had he become such a horn dog? Perhaps the two weeks really had gotten to him. His balls hurt again, they throbbed in time with his heart. Jay? Jay?

His attention inward broke as he blinked. "Jay, what did you want to eat?"

"Oh, I'll have the steak, medium rare. Baked potato."

The waiter smiled as he took down their orders and turned on heel to put them into the computer. Jay shook his head to clear it as he watched the waiter walk away.

"So, what're we doing for the rest of break?" Dani asked. "Want to go to Reno for a night?"

It sounded good to Jay. "Yeah...Then we could take that new Mag-lev train over to SanD and spend a weekend at the beach."

"If we're gonna do that, I should get a new swimsuit." She pulled at the front of her shirt. "For some reason this is really tight."

Jay gulped. "Dani, I..." He started to tell her about his suspicions when their food arrived and Jay broke off what he was saying. The plates were set on the table and they were told if they needed anything to just ask.

"What were you saying Jay?" Dani asked, a forkful of manacotti following her question.

"Just that today at the lab was interesting." He replied lamely. He dig into his potato to cover the awkwardness in his mind.

"Oh? What're you working on?"

"Just doing tests for a experimental cure for AIDS. It is, in a sense, a virus engineered to take over HIV positive cells and disable them. Just how all of it works is beyond me, but I've seen it in action, so I know it's effective."

"So,what happens to the disabled cells?" Dani asked, half of her plate already eaten.

"They pass out of you, just like any other cell that has died."

Dani 'ahhed' at his explanation and for a few moments they ate silently until Dani snapped her fingers. "How does the cured person recover cells that have been removed?"

"I'm not really sure. They said something the other day about having the virus injected as a vaccination to prevent viral infection but, I don't know if they ever figured out whether it would work or not as a after the fact thing."

"So, at this point then, what would happen to some one exposed to it?" Dani's question echoed his own.

"I asked the same thing. They said they didn't know."

Dani nodded like that was an acceptable answer and the two resumed their meal.

Across town Dr. Finksworth was in the lab checking on the samples after eight hours. The test on having the virus make new cells seemed to be going well. The exposed cells had been cured of the HIV and now twice as many working white blood cells were living in each of the dishes. Dish after dish was a positive result. Even though a few dishes had mixed results, but the experiment was an overwhelming success.

The old British man scrawled the numbers of the dishes that had been negatives, at first they seemed to be dishes that were exposed to the brief fire and he noted it may have been the heat that had prevented the reaction. Finksworth didn't rule out a double blind though, these things were known to happen in trials like this. Clicking off the lights the doctor went home for the night. His mind at ease with the experiments outcome.

At the same time Jay and Dani were on their way home. Jay's mind was filled with both the burning need to fuck and the chilling doubt that he was carrying a virus with an unknown effect. The walk from the car to the apartment was the toughest few feet for Jay that he had ever tread. The air about Dani was almost intoxicating, and he had been hard since they had first gotten in the car almost an hour and a half ago. Jay followed Dani up the stairs to their second floor apartment. From behind he could swear her ass filled out her pants more than they used to.

The sound of the front door swinging closed gave Jay a sick feeling. A feeling not helped by Dani seeming oblivion of the 'please take me now' signals that she was putting out as she leisurely took her shirt off. From behind Jay could have sworn she really was a bit heavier up top. She turned and had a concerned look on her face.

She put her hands to her chest, the flesh of her breasts peeking over the top of her bra. "Do these look bigger to you?"

His cock twitched in its a agreement. "Um..." Jay said intelligently. They seemed bigger, now that he looked at them. He wasn't sure though or, more accurately, didn't ant them to be. She reached behind her back as she walked slowly towards him and with a sigh she unhooked her bra. Throwing it aside, pressing her naked torso against Jay. Oh yeah, they were bigger Jay said to himself.

"I don't know what's come over me." Dani cooed as she drew circles on his shirt. "All I can think about it your cock." She undid his shirt as she worked her way down his body. Jay's cock strained against his pants, eager to be played with again. "It's been like this since I got out of the shower."

As Dani pulled his pants down his cock sprang free. Looking down Jay realized why he had been so uncomfortable. His hard cock was twice the size it had been just over an hour ago.

If its improved girth gave her pause Dani didn't show it. Purring almost, she nipped at his giant shaft and then slid her mouth over the tip.

The duality of her soft tongue nestled the against the bottom of his cock while the hard roof of her mouth rubbed his head made Jay's knees go weak. Something in his mind changed as Dani went all the way down his shaft. He had the driving urge to cover as much of her with his cum as he could. Only a minute of Dani's blow job had passed when he felt his balls clench. He forced Dani's head all the down and held it there as a torrent of cum blasted down her throat. She fell back sputtering and without hesitation Jay straddled her as his cock continued to spurt , leaving her face, neck, and chest spattered in sticky goo.

She arched under him, her purr turning into a long low moan as she ran her hands up her body to her chest and began to massage her cum soaked breasts.

Jay set his cock in between them as she played with them. Her nipples teased the sides of his shaft as Dani rubbed them along it. They were quite warm and surprisingly soft. Every few seconds they would pulse, then grow a small margin. It wasn't long until Dani's handfuls had grown around Jay's cock, effectively devouring it. Jay's bucking increased as the pulsing slowed. They were quite large now, about the size of melons and the feeling of them growing had completely pushed rational thought out of his mind.

"Dani-!" Jay gasped as his cock let loose another stream of cum. Most of it hit her in the face, a little landed on the carpet. Dani motioned Jay off of her and spun to her hands and knees so the tips of her breasts are settled in the cum that had missed her. As she bent over Jay couldn't help himself. He flipped her skirt up and pushing her panties aside, slid his cock into her slit. It was an amazingly tight squeeze now, but he pushed on anyway. Dani didn't flinch at the penetration. Instead, her moans grew louder the further he slid in until his hips were pressed against her ass and she screamed.

"YES! FUCK ME! FUCK ME BIG STUD!"

Something in those words triggered a snap within Jay and with far more force than he'd ever used he pressed her forward, squashing her torso into the rough carpet. Her ass jiggled each time he hammered all the way in. Harder and harder he pounded, the sounds of them coming together echoing loudly in the small room. With each thrust the world around slowly became a blur, there was only the motion of hips and the moans of pleasure from his bitch. His balls tightened and he tried to inch further up inside her as with a few throbs he filled her tight hole to bursting with cum.

"Harder!"

The sound of Dani's voice from just a few hours ago follows him back to the present and as the past day finishes in his mind Jay realizes he is almost painfully hard. Opening his eyes he is met with a surprising sight: his erect cock. A little bigger around than his arm, it had to go past the two foot mark! The huge veins covering it pulse in time with his heart, conveying the sheer impossibility of his new member. He tries to reconcile the facts, but with each pulse his mind becomes hazier and he quickly sinks back into the mindset from the night before. In seconds his misgivings are wiped away by one word: FUCK!

Dani lets out a sleepy sigh and Jay crouches behind her, his mind fixated on her exposed slit. It takes both of his larger hands to control his enhanced cock. She is already dripping wet as his tip brushes against her; as if she had been anticipating his surprise. She purrs and grinds her hips into him. All restraint gone Jay spears her with his cock, her cum sculpted body taking every inch. Somewhere in the back of his mind, Jay wonders what will happen if he comes again, and it shudders with anticipation...

Afterthoughts

When I wrote this as a one shot almost six months ago, I had no idea Cure would become the epic is has evolved into on FA. I don't know if i should be proud of it or not, but Cure's pushed my writing far harder than any other thing I write. So enjoy this chapter, there are more to come.
