GEM: Genetically Enhanced Male

Jake's brother read the ad out loud

"Applicants requested for medical experimentation. Six months Quarantined service required for studies in viral infection. Free room and board, plus $9,000 at end of six month service. Call for interview 555-6969."

They had just been evicted, for non payment of rent, from their second apartment and six months with a cold didn't sound half bad. The $9,000 wasn't anything to sneeze at either.

"Let's see...," said Aiden, his twin brother. "9,000 divided by 6 is......Fuck! I can't divide without a calculator!"

"Here!" Jake said, handing his cellphone to him. Aiden pushed the buttons and came up with a figure. "That's 1,500 a month! And with BOTH of us in, we would make 18,000 dollars! That would be bomb! Let's check this out!"

They called the number and were directed to a drab building on the university campus. The air inside smelled of isopropyl alcohol, and reminded them of a hospital. They were put through a battery of tests that covered just about everything, including penis size and muscular development. This seemed strange for viral research, but doctors were that way.

The doctor, a man in his mid fifties but still trim and bright eyed looked them over. "Twins! That is very exciting. It will be interesting to see if you are both affected the same way by the virus."

"You mean we're hired?!" Aiden blurted out with obvious excitement in his voice.

"We will see what the test results yield. But yes, I do think we can use you." the doctor said with a warm smile. "What does your family think of this?"

"Oh, we aren't very close to our family...", Jake started to say when Aiden broke in with "We're orphans."

"Perfect.", the doctor said, adding, "You will be notified in two days. If the tests turn out well, be prepared to move into the research facility immediately." Then he turned away.

The next two days were very long. It seemed like they would wait forever. The experiment was all that Aiden could talk about. Then they got the letter. They had been accepted. They were to meet the van to the experimental center at the same building they had been tested in.

The van took them a long way into the country. At last they rounded a curve and there was an old institutional looking building looming up behind a tall chain-link fence. The place used to be an asylum, but had now been converted into an experimental center. It looked very imposing and still had bars on the lower windows. But there was now a brightly colored logo and sign on the lawn proclaiming it as a Virus Research Facility.

When they arrived, a swirl of attendants met them at the door. The staff seemed very interested in them and followed their every move with interest. Their suitcases were taken and they were escorted to the orientation center. There they were briefed on the policies of the facility and given swipe badges with their code numbers on them. "GEM-26A" was inscribed on Jake's and "GEM-26B" on Aiden's. He wondered what GEM stood for. They were led to a concrete cell for exposure to the virus. Once in the cell, they were stripped by hazmat suited attendants and their wrists were securely fastened together. The wrist restraints were then attached to a bar that hung vertically just below the ceiling of the chamber and they were hauled up to standing position, their arms held comfortably over their heads. The twins hadn't known what to expect, but it certainly wasn't this.

Jake and his brother stood side by side. They were stark naked, their wrists tied over their heads exposing their bodies. They stood there, feeling very naked and vulnerable. They looked each other over, noticing the family resemblance. They had tan skin, but blond hair. Both were lean, and had had trouble gaining much weight in fat or muscle. Both ordinarily sported uncut, average five inch cocks, which seemed slightly shorter due to their long, ungroomed pubes, but the chamber’s cold air had given them cases of shrinkage.

The heavy steel door opened, and a naked man entered. He was completely nude, except for a smooth round heavy silver collar around his neck. He was incredibly sculpted; a perfect V shaped torso with developed shoulders and muscled arms. His pecs were well developed and had slightly oversized and very erect nipples. His six pack tapered cleanly into his waist and accentuated his enormous member, which was already erect and had to be at least 11 inches long. His  body was completely hairless except for his brows, lashes and the short cropped hair on his head. His legs, like the rest of his body, were muscled but well proportioned. His jawline was crisp and strong and an unbearable smirk was plastered on his face. Jake became embarrassed by the thrill that he felt looking at another man’s body only to look up and be captivated by his amazing eyes.

His eyes were Turquoise! They had a brilliant predatory gleam in them as the strange adonis looked at the two helpless boys. The man walked right up to him and stared deep into Jake's eyes. Jake stared back, trying to see the telltale sign of colored contact lenses, but they weren't there.

"Your eyes!..."Jake said in amazement.

The man flashed his teeth knowingly, reached out and gently took Jake's head in both hands. His eyes came closer as he leaned toward Jake, and his dick spreading warm precum on Jake’s belly gave him a thrill. Then without a word, the man kissed him.

This kiss wasn't a friendly peck, but a deep French kiss. The strange man's tongue surged into Jake's mouth and down his throat. It felt as if it were a foot long as it went deeper into his throat, much deeper than any tongue had a right to be. Jake started to feel the panic of the gag reflex. The man stopped his advance and explored every inch of the inside of Jake's mouth with that incredible tongue. He felt violated, and astonished!

After the kiss, the man smiled at him and licked down his chest, circling each of Jake's nipples with his tongue. He gently licked them until Jake was hard, and then he continued licking down his torso.  Jake could feel the tongue travel all the way down to his dick, before the man completely squatted down and hit the ground with his still engorged cock. The man licked the slit at the end of his penis before pushing his tongue in! Jake felt the man’s tongue go deeper into his dick and then body when the man engulfed his penis in his hot mouth. The incredible man began pumping his head up and down Jakes cock, bringing him closer and closer to the edge, when Jake felt something incredible happen! The man’s tongue started to contract and Jake felt the tongue fill his prostate with some foreign liquid. The man released Jake’s dick from his mouth just before he could cum, jumped up and grabbed the bar overhead, wrapped his thick legs around Jake’s torso and lowered his ass onto Jake’s dick. His ass was already lubricated, slick and tight, and Jake immediately came, emptying his load deep into the man. Jake thought it was over but then the man pulled the bar that Jake’s cuffs were attached to down, till it was inches from the ground and Jake was bent over. The man walked around Jake and buried his smooth shaven face into his ass. Jake felt the man’s tongue circle his asshole, and then felt the tongue slip inside. He was immediately hard again, and the man’s tongue wiggled it’s way into his virgin hole, until it was deep inside, and it began contracting in the same way it has in his cock. The man pulled his tongue out as it came, spreading its slick ejaculate throughout his ass. Then, without a warning, the man lined his dick up and impaled Jake’s ass. Jake howled in pain as the man fucked him, using his strange tongue secretions as lube, until the man came, deep inside him. Jake was in immense pain, but as though he were controlled by another force, he came as he felt the man pumping him full. Jake finished cumming, but the man kept it up, his ejaculate flooding his ass, but unable to come out, the only exit blocked by the his enormous cock. Soon Jake felt a burning pain, as the cum entered his small intestines, and eventually his stomach, but then, as suddenly as the man entered him, he exited. Jake expected cum to pour out of his ass, but to his surprise it all stayed inside, still travelling into his stomach. The man released his shackles, picked Jake up, kissed him deeply a second time, and gently put him down in the corner, in too much shock to do anything when the man began his assault on his horrified brother. Jake stared in amazement as the man performed the same ritual he had just gone through. The stranger stepped back after Aiden had been lowered to the floor, and smiled knowingly at the exhausted pair. The brothers watched as the man turned and strode provocatively away, his ass jiggling enticingly. They noticed a large tattoo on the his ass that resembled a scrollwork S with a bar through it and oblong dots inside each curve. They wondered what it could mean.

Aidan rolled onto his side facing his brother. He looked at Jake, savoring the afterglow of orgasm, but feeling incredibly full from the load the man pumped into him and sore from the unexpected violation the stranger had committed. He was voraciously hungry, as he always was after great sex, but he was content to lay there for a while. They stared at each other for a long time after the naked man left. Neither saying a word, but sharing the same secret thoughts. Thoughts too embarrassing to talk about out loud.

Jake awoke to find that he had been sleeping. His hands were free, and he was laying naked in a soft warm bed in a private room. He found that his room connected to a suite of rooms that included his brother Aiden's private room. They were quite comfortable, and had TV, good meals and books to pass the time. They talked, but not about the adonis. Most of the talk was about how they would spent the 18,000 dollars when this was all over. Jake started to wonder if the man had been a dream.

The doctor that had examined them before came in once or twice a day to examine them. So far they had felt no symptoms, but the doctor assured them that would change.

Two days later, Jake developed a terrible rash. It was all over his body, but his asshole and pubic region, his underarms, and in and around his mouth were particularly affected. He soon also began to experience muscle soreness across his body. He discovered that his brother had the same symptoms and they wondered what they had been infected with during their encounter with the man. They talked about the encounter for the first time late that night. Jake had extremely erotic dreams that night, and in the morning, hi throat was too sore to talk.

Hi throat felt like it was on fire, his nose ran, his voice became lower, and his tongue swelled up and seemed to fill his mouth. He started to lisp harshly when he did talk, but his lisp was improving as he got used to the condition. His whole neck hurt, and he hardly talked at all.

Then Jake noticed that his balls ached. Then they hurt! The doctor assured them that this was all part of the virus that they had been exposed to, and that they would be fine in about a month. The rash began to intensify on his genitals and nipples, and the next morning he awoke to find that his nipples, scrotum, and penis were swollen and sore to the touch. That day Jake and Aiden both experienced muscle cramps, and for the next week they got a few cramps each day.

They started experiencing severe headaches mostly centered around the eyes and back of the head. The rash started to clear up, but they noticed that their body hair was thinning. Soon Jake’s rash was gone from everywhere but his dick, balls, and nipples, and so was his hair.

Jake's thoughts turned mostly to sex. He was having crazy fantasies in which he was fucking everything in sight. He started spending more time in bed. Supposedly to shake the virus, but in reality it was so he could masturbate, which he did almost constantly. Since he had lost his pubic hair, he couldn't keep hi hands away from his newly bared asshole. It just felt so GREAT to touch it. Hi orgasms were getting stronger too. Hi cock still hurt too much to stimulate it, but his ass felt great. He noticed that he got a throb of pleasure whenever he contracted his sphincter tightly, and especially when he had something to squeeze on, like his fingers.

He found himself constantly fantasizing about sex. Sex with women, men, animals! He even thought his brother was starting to look really good.

Finally the rash from his cock and nips had subsided, but they still seemed swollen

He hadn't been dressed in a while, so when his brother came into his room naked and with an enormous hardon, he didn't know what to think. His first thought, naturally, was that they were going to have sex. He was excited about the prospect, and sprang from his bed to meet Aiden.

"Look, I have to uthe two handth to grab my dick.", Aiden said, making a ring with both hands around his engorged phallus.

Jake looked down at his own dick and saw that it was growing hard and was now incredibly long and thick too. It reached full mast and slapped his abs, the head brushing pre onto the underside of his pecs. He looked up at his brother, and for the first time he noticed that his eyes had turned turquoise! He saw the look of astonishment in Aiden’s turquoise eyes and realized that his own eyes must match.

"Watth happening to uth?" Aiden lisped. "My muthelth are growing. I didn't thay anything before becauth I didn't believe it. Now I thee yourth! They're beautiful!" And he stared at hi brother's large, cut, and muscled body, his enormous cock swinging enticingly, and his large nippples standing up from his thick beefy pecs.

Aiden stood there, his hard hairless body posed for Jake’s benefit. Jake stood stark naked, staring at his brother's hairless cock and low hanging balls. Aiden reached out and touched Jake's left pec. He squeezed it and brought the nipple between his thumb and forefinger.

That was all the invitation Jake needed. Overcome by the uncontrollable urge to suck his brother’s nipples, he leaned forward saying, "I have been tho horny lately..." and grasping Aiden's ass around his body with his hands, he opened his mouth and stuck out his tongue. It reached out a full 5 inches before he noticed it's length, and there was more inside still. The tip of his tongue touched his brother's nipple, and he thought of his tongue. It was the first time he had seen it that far out before, and he was shocked. He stiffened, retracted his tongue and stood up straight. His brother, a dreamy look in his eyes, hugged him, pressing his body against his own, then kissed him. Deeply.

Aiden's long tongue snaked down his throat, and he didn't gag. That reflex had apparently been suppressed, only to be replaced by the most erotic stimulus he had ever felt above the waist. WOW! His throat felt like the inside of his ass, only in his neck. Aiden started slowly fucking his throat with his long tongue, moaning with pleasure, and Jake realized that his tongue must also feel pleasurable stimulus. He pushed his tongue deep into Aiden's mouth and felt the double stimulus of fucking and being fucked. They hugged their bodies closer as the first waves of orgasm coursed down their bodies. It felt like their heads would explode. When they pressed their hairless cocks together, they both experienced earth shattering orgasm.

Now Jake fucked his brother's throat with his tongue and came so hard, pumping out thick liquid, he almost passed out. His first tongue orgasm. Then a throat orgasm. Soon Aiden started working lower, licking all over Jake’s muscled torso, exploring every crevice with his tongue. When he finally got to Jake’s cock he circled his tongue around the head and then pushed into the slit. Jake shuddered in ecstasy as his enormous member got fucked by Aiden’s tongue and Aiden shook as pleasure radiated from his tongue. Finally, Aiden sucked down Jake’s enormous cock craning his neck to get it into his throat. Both were in pure pleasure, Jake from having his penis fucked by Aiden’s tongue while simultaneously fucking Aiden’s throat, and Aiden, from fucking with his tongue while being fucked in the throat. Aiden felt Jake’s cock throb so hard it seemed like it would blow a gasket when he hit orgasm, his throat throbbing around Jake’s cock and his tongue pumping ejaculate into Jake's balls. Jake too began cumming, but his balls only filled up, Aiden's tongue blocking his cum from escaping. Finally Aiden pulled his tongue out and his throat was flooded with Jake’s cum, which he greedily swallowed. 

Aiden then guided Jake to the bed and lay him down. He climbed on top of Jake, buried his face in his ass, and penetrated it with his tongue. Jake yelled as he felt his brother’s tongue deep in his ass, stimulating his prostate and going far deeper than Jake’s fingers ever could. Aiden was in heaven, his tongue stimulated by the contractions of Jake’s ass, his nose buried in the musky scent of Jake’s taint, and the salty flavor of the lube being secreted by Jake’s ass. Jake turned over, pushed Aiden to lay down on the bed, and squatted over him. He lined his ass up with Aiden’s cock and slowly sat down, groaning when the head of Aiden’s cock audibly popped in. He continued to lower himself onto his brother, savoring each inch that entered him. Finally, he felt Aiden’s balls underneath his own, and he contracted his ass and began to ripple the muscles inside, effectively massaging Aiden’s hardon. He then began bouncing up and down, grinding the enormous head of that penis into his prostate. Aiden sat up, and french kissed his brother, throwing himself into ecstasy. Jake wrapped his legs around Aiden’s hips and Aiden got off of the bed, standing up to carry his brother to the chair in the corner. He sat down on the chair with his dick still buried inside of his brother and sat down. Jake released his legs from Aiden’s hips and placed his feet on the bars under the chair. He pushed himself up and down and leaned down to kiss his brother again, who eagerly shoved his tongue down Jake’s throat. Jake reciprocated and they sat there, embracing as they fucked with both their mouths and their waists. Finally, they reached an earth shattering climax at the same time, and Aiden flooded Jake’s ass with cum, jake plastered Aiden’s chest and both filled each other's mouths. Both moaned animalistically, and Jake pulled himself off of his brother’s cock. Aiden’s cum did not leak out,  however, but simply drained into Jake’s stomach, much in the same way that the mysterious man’s had. This orgasm, however had not tired them, but rejuvenated them for more, and Jake kneeled down infront of Aiden and began penetrating his cock with his tongue. They continued fucking the rest of that day and late into the night, only retiring because they were too exhausted for more. They slept with Jake spooning Aiden, his cock buried deep inside Aiden’s ass. 

They awoke the next morning to find the Doctor sitting at the chair at the foot of their bed. “You’re awake” he announced, and he looked at them with a proud smile. "Look at you two. Nearly a perfect match. The splicing affected you both the same way. I only wish you were past your virulent stage. The Senator's party would love to see you. In fact, I bet we can even go for an increase in funding after this." The doctor then explained that they had been enhanced by a mutant gene, introduced by a virus carried by Tom, GEM-17. GEM stands for Genetically Enhanced Male and he is the seventeenth specimen to carry the strain. The twins had puzzled looks on their faces and they squirmed distractedly. When he explained that Tom was the strange naked man they had met the first day, they both sat up and showed acute interest.

The mention of that first encounter sent a thrill through both of them. "Is he thtill here?" asked Aiden, a glint in his eye.

The doctor smiled, "Yes, he is still on the premises. There are also genetically enhanced females that you will want to meet. I intend to introduce you in a couple of weeks, when the virus recedes and you are fully matured. You see it gets better.", the doctor said. "You may notice that your bodies are more muscular and more sensitive to pleasurable stimulus than normal. Your buttocks and pectorals have been specifically enhanced, and your nipples sensitivity has been increased. Your tongues and throats have been enhanced into sexual organs. Your penises are larger and more sensitive to pleasurable stimulus, as is your rectum. You now have increased control over your anus, and rectum, which now self lubricates and can be stretched far more than previously. Your body and facial hair has been genetically removed, so no more shaving for you boys.

Your eyes have changed to turquoise. Kind of a genetic trademark of mine, that allows us to recognize our enhanced specimens.

You may also have noticed your thoughts turning to sex lately. That is also caused by a genetic re balancing of your brain chemistry, resulting in insatiable desire for sex in any form, subservience, and a desire to please. These desires extend into masochism, and a strong desire to be bound and forced to perform sex acts as a total slave. You have probably experienced gay fantasies as well as heterosexual, another genetic signature.

So boys, you are now genetically mutated sex slaves. Does that thought appeal to you?"

The doctor looked at the brothers. Jake with his hand between his legs fingering his ass as he stared vacantly smiling at the doctor, and Aiden was tracing his hands up and down his torso, smiling seductively flexing his muscles for the doctors benefit. “Fuck me” he said.

"Of course it does", the doctor smiled, "Of course it does."
