The Erotic Mind-Control Story Archive

Being a courier was the best! Jill loved feeling of her bike, the sheer rush of speed, the challenge of threading her way through the ever-shifting traffic... she even loved the occasional confrontation with the idiots in the rolling tin pollution boxes. Now, if she could just get this stuff to the labs on time and back to the office she could probably get another delivery before the day was over.

Oh god! She saw the door open a split second before she piled into it, no time to turn away.

She woke up laying on her back surrounded by on-lookers. Once she was sure she was relatively unharmed, she struggled to her feet, aided by a couple helpful bystanders. She recovered her bike and bag and brushed herself off. Wincing, she discovered that she had cut herself and was all wet on one side. Oh god, oh god... She was almost giddy with relief to discover it was just her crushed water bottle- it soaked her side and the bag. Luckily, most of the stuff was packed in plastic or Tyvek envelopes.

She hopped on her bike to finish the delivery, then limped back to the office and on towards home. She stripped down and ran a warm tub. She checked herself out in front of her big mirror to assess the damages.

Oh god. The cut itself was small enough, high on her side, about where her elbow hit. It looked deep, though, and was surrounded by a horrible bruise. Everything else looked pretty much OK. Her slender 5′5″ body with so little padding generally bruised easily, and most days left some souvenirs behind.

She checked her head, running her fingers through her rather dry and kinky orangish hair. She examined her long face with its slightly too prominent nose and slight acne scarring. She saw a new bump over one of her ‘almost green’ eyes. She recalled, as always, one boyfriend’s faux-joking comment that they were ‘olive drab’. Cute.

Hmmm, a bit of scraping on one shoulder, some tenderness on her left breast. ‘Good thing they aren’t larger’ she thought with a sour grapes attitude. She hated that she barely filled out her A cup sports bra, but she figured that with all her riding, she’d have bruised them purple by now if there had been anything there to bruise.

Scrapped but slender hips, a big tender spot on one butt cheek (she often wished she had a little more padding there), and some more scrapes on her knobby knees. She slipped into her hot bath and sighed, wincing occasionally as the soap touched her sores.

Drying off, a little first-aid, a light dinner, some TV, and early to bed. Jill so dearly ‘loved’ her exciting social life. Only 20 and living like an old maid. At least she had her bike and job.

The next morning, she was stiff and sore, and felt... off, like she was coming down with something. Her day got even worse when she was chewed out at the office.

“The client is furious” her boss, Jack, screamed. “A bottle of some valuable stuff was delivered broken and you didn’t even stick around to process a damage claim. They say the stuff is worth millions, and it was ruined. I’ve got to fill out reams of paperwork over this”

Jill was alternating between being ticked off (she was knocked flat but still finished the run and THIS was the thanks she got?) and being a bit afraid (Did I get any on me? What the hell was this stuff? They were not supposed to handle dangerous stuff!)

She brought that last bit up with her boss, and he began to waffle. Turns out that he took the job partially as a favor and partially for a big bonus fee. Both parties knew they were taking a risk, and the lab had no plans on suing, but... When she pressed him for what the stuff was, he called it some sort of growth hormone or steroid or something. Jill was relieved it wasn’t some sort of poison.

Jill told him what she knew and that nothing got on her, and picked up her first run for the day.

Her ride started rough. Even with Tylenol, green tea, and her warm riding gear, she was cold and in pain. Her legs and hips hurt. Her back was killing her. Her first delivery included several flights of stairs. ‘Figures’ she thought grumpily as she limped up the steps.

As morning wore on, however, things got better. The chill left her bones, the aches and pains lightened up, and she caught her second wind. The rest of the day breezed by.

“Oh, god. I’ve got to get some new gear” she told herself as she checked out her reflection before taking her bath. She rubbed at the red lines her clothes left on her. She liked them tight, but not this tight. She also noticed her feet felt like they were released from a prison as she slipped her shoes off. She was glad to notice her bruises seemed to be healing up nicely. Even the cut looked a lot less nasty today. ‘Must not have been as bad as I thought’ she mused to herself.

Other than being hungrier than usual and drinking nearly a half gallon of milk, her night was the same ol’, same ol’.

The next morning she was up and cheerful with the first buzz of her alarm. She was pleased to feel so awake since it normally took her a couple swats at the snooze button before she was ready to face the day. She treated herself to a bigger breakfast than usual with lots of cold OJ. She did wince a bit as she tugged on her usual Lycra biking shorts and sports bra. She reminded herself to get some quick shopping done after work. Everything was just so dang snug this morning! Even her most comfortable undies were riding up on her a bit.

She felt glorious riding into work. The sensations of speed and wind even made her nipples a bit crinkly. Of course, she was irritated that the seating adjustments were out of whack a bit. ‘First my clothes, now my bike.’ She mused. ‘What else can get weird today?’ she thought as she adjusted the seat and handlebars.

The universe answered her as she rode into heavier traffic. Her balance was off just enough that her hot-dogging antics and split-second timing were screwed up. She missed a bad spill by a hair’s breadth by yanking on her bike with more strength than she had ever displayed before. She pulled over and thanked the gods for the adrenalin rush she assumed gave her the ability to recover. On the plus side, she -did- note that she wasn’t feeling particularly winded yet.

She grabbed some tools in the office and adjusted her seat and handlebars again, surprised to see she had to move them over an inch to get comfortable. Oddly, everything in the shop seemed just a tad closer or farther away than usual- sort of the sensation you usually get with new glasses. She decided to get her contacts checked and shrugged it off.

After work, she stopped at the local sporting goods store for some new riding clothes. She adamantly refused to dwell on the implications of doing most of her clothing shopping in these types of stores. Jill picked up a couple new pairs of tight biking shorts and sports tops. She was in the shoe department when she noticed that she was having to select an entire size larger to fit.

Now she felt weirded out. There is no way in hell her feet should have grown a size. She plopped into one of the chairs in the shoe aisle. ‘Oh come on’ she railed at herself. ‘There has to be a logical answer to all this’. Her clothes were tight- she was either retaining water (even though it wasn’t really that time of the month) or the old stuff was shrinking... all at the same time and at the same rate. The odd sensation of things being easier to reach upwards and further away downwards was because her glasses needed checking... wasn’t it? Her balance on the bike, the burst of strength, the better endurance... all logical and normal, right? Right??

She left her purchases on the chair and fled the store. She hopped on her beloved bike and steadfastly refused to notice that the sensations felt different. She got home, took a fast hot shower, drank a protein shake for supper, and went to bed desperately trying to not think about anything changing or about any growth hormones and such.

The next morning she got out of bed, took a quick self-assessment, and promptly threw up. She called into work with a weak and shaky voice and got the rest of the week off. She staggered back to her mirror and stared. The first thing she dwelt on was that the top of her reflection was a bit above the top of her mirror when is was supposed to miss by about 2-3 inches. If she was 5′5″ before, she figured she was about 5′8″ or so now.

Hair... has grown out at least six inches, mostly overnight. It went from dry and frazzled to soft and thick, laying in sensual waves. Had it really gone from an orangish to strawberry blond? Her face- her comfortable old freckled, acne-scarred face was clear, smooth, and lay over what looked like actual cheekbones. Her nose had shrunk, and her eyes were... were... were an unbelievable green. Her lips were even plumper- she could not wait to kiss someone with them!

Her body had changed just as incredibly. Arms and legs filled out to nicely rounded and toned limbs. Tight tummy, globular bottom cheeks, and breasts! Real, live, jiggly breasts! She was a 32A-24-30 before, and figured she was now about a 34C-22-34. Not sex goddess material, but certainly ‘pretty girl next door’ quality.

She was so entranced by the changes that it took her a few minutes to register that there was virtually no hair below her face, just smooth skin. Her usual kinky bush was now just a soft patch like she might have had at 15 if she had hair that downy. It took her a few more minutes to discover that her clitty was bigger as well. It was a pea-sized ball that she discovered tended to magnify the sensations of her walking, wearing underwear, and so on.

When she slipped on a pair of far-too-tight panties, they rubbed on the little nub and sent shivers through her new frame, triggering her nipples to crinkle up in playful sympathy. Jill had not felt such electricity in a while, and decided the hell with it- she had the day off! She fell back in bed and made luxurious love with herself. She instantly found that her skin was more sensitive than before, and that her sweet little pussy was a silky heaven for her exploring fingers.

A couple hours later, she lay in bed, her mind slightly blown by the orgasms she experienced. Dear lord, she thought to herself, if my own fingers made me feel like that, what would a nice thick cock do to me?

The thought seemed to have opened some floodgates in her mind. The rest of the day was spent wondering about sex- who could she call? Where could she find a fun guy? How does one arrange a one-night stand? Should she lay in a supply of condoms? She prepared lunch for herself, then kicked herself for not having gone out because then she might have found some guy... and lapsed into a pleasant fantasy of nameless sex.

All at once she realized it was nearly three o’clock in the afternoon, and she had so much to do! She took a long, erotic bath and towelled herself off, tingling as the nubby towel touched her all over. She took her own measurements and found her guesses pretty accurate. Dressing herself in some sloppy sweats, she went back to the mall- but this time stayed away from the sporting goods store.

Stores she had never really paid attention to drew her- exciting clothing, sexy lingerie, fun-looking shoes... her pussy was a-quiver as she window shopped some of the teen-oriented shops she had always strode past with an attitude of slight derision before. She began to picture herself in high heels and tank tops... a shiver ran down her neck as she entered the store and began to assemble an outfit to change into.

The Jill that left the mall several hours later was a far different person than the shy, quiet girl that delivered the mysterious chemicals just a couple days earlier. This Jill had several large bags from trendy stores, her hair done in a bouncy style and featured sparkling earrings dangling from each ear. Her face had been made up and looked angelically sexy, highlighted in lightly tinted shades. Her clothes were colorful, sexy. and caught the eye of every guy she passed, leaving a wake of light perfume that further captivated onlookers. Her height was augmented with short heels that clicked merrily as she waggled her bubbly butt down the mall towards the bike rack.

As she approached the last store before the exit, a young man accosted her. “Need some help with those bags?” He asked.

She looked him over and approved. He was about her age and looked good. About six foot tall, medium build with a hint of muscle, dressed nicely in upper-end clothes. He had good hair and a smile that tugged at her heart... and lower down. “Sure” She replied, handing him the two larger bags. “My bike is just outside.”

“Bike?” He smiled. “How are you going to carry all of this on a bike? For that matter, isn’t your outfit a bit wrong for bike riding?”

She stopped cold. She had not thought of that, but there was no way she was going to be able to ride in this outfit. What the hell was she thinking?

“Tell you what, my car is just around the corner. I have a bike rack on the roof and I would be happy to give you a lift home. If you rode here, you probably are not too far out of my way.”

Jill waffled. On the one hand, he as a guy, a very good looking guy... a very good looking guy that she would bet had a nice big cock... a nice hard cock... She shook her head. He was a stranger. There was no way this was a good idea.

“OK!” She said perkily, turning in the direction he indicated with an extra wiggle in her walk. As they walked, they talked and she learned that his name was Tom, that he lived in some nice apartments about five miles past her place, and that he was a very junior partner at a local ad agency.

Junior partner or not, she was pleased to see a newer compact SUV that he effortlessly hoisted her bike onto (her nipples tightened at the display), and had nice leather seats that felt wonderful on her silk and cotton-encased bottom. On the drive, they discussed books, music, food, and the other ‘safe’ topics and she felt more and more comfortable around him. The ride to her house was far too short and she was reluctant to leave. Just as she was starting to open the door, he asked if she might be interested in getting a bite to eat, considering the hour. She gladly accepted and they were off.

Dinner led to dessert, then to a nearby club for a nightcap, then back to her place, where he carried her bike up for her like a true gentleman. At the door, she gave him a quick peck on the cheek and invited him in for coffee.

As she had never drank coffee, she really could not fulfill this offer, so made him a counter-offer that he enthusiastically accepted. Her sensual side raged once more and soon he was devoid of clothing and laying back on her couch. His cock was everything she had hoped for and not only looked perfect, it tasted wonderful! He had excellent control and it took her some time to persuade him to come. When he did, the effort was worth it!

As she serviced him, he had been kissing, touching, sucking, caressing, and stroking her all over, and she was primed for an explosion. She left his cock and positioned herself to straddle him. She was so wet that she slid most of the way down him in the first stroke and she revelled in every exquisite inch! She came in the first couple strokes, and then settled in for a real workout.

She started off on top, then rolled and pulled him off the couch on top of her. She discovered an incredible flexibility as she brought her heels to her ears and egged him on to plunge harder and deeper! She rolled over and got up on her knees and had it doggy style, yelling and begging him to fuck her, to use her, to come deep inside her.

Tom was amazed at this wild woman. It was like she was a nympho that had never seen a cock before, but he was determined to try to wear her out. After using nearly every piece of furniture in the room without ever quite making it to the bed, they fell asleep in each others arms on the couch.

In the morning, Tom’s watch alarm sounded, waking him with a yelp! He gave her a huge kiss and begged her forgiveness but he had to run. They traded cell numbers, and he left in a rush. Jill took a huge stretch and nearly purred with contentment. She strolled over to her bathroom and did her morning toileting, then stood and gazed in the mirror.

-eep-

Dear God! She had changed again! Maybe another inch taller, her hair was longer and streaked with color. Her face was somehow reshaped? Redefined? She looked more like a model now than the girl next door. Her eyes were bigger, lashes longer, lips sexier. Her skin was a wonderful creamy tone and as soft as down.

Her body was approaching lush! Her hips were wider and her buttocks were perky and perfect! Her belly button was even cute! Her tits were bigger, but firmer as well, standing proudly with nice sized nipples that pointed up like eager little troopers.

She broke out the tape measure to find herself 5′9″ tall, 35D-21-35. God she was gorgeous. She played with her bouncy boobs and stroked her trim tummy, and slipped her hand downwards to discover that her clit was poking out waiting for her.

It was another long morning, and she did not get around to her bath until nearly noon.

The two men in the small lab in the big building were nervous. They looked to barely qualified as men, more like high school science nerds, but they certainly qualified as nervous.

“How can we tell the boss about this” The first, Marvin, whined.

“What part of it? The fact that we changed the growth serum to a bimbo-making formula without telling anyone? The fact that the bottle was broken and soaked through the entire delivery? The fact that the building receptionist got some on her and is now a boob-alicious, over-sexed fucking machine? Or maybe you are referring to the fact that she is blowing you while letting me butt-fuck her under the table? Jeez- maybe you mean the minor detail that she is our bosses niece and he’ll certainly kill us if he sees any of those pictures you took.” Jefferson puffed.

“Hey, you are the one who posted them on the web!”

“OK, but I still say nobody will recognize her with her big boobs and red hair as long as we kept that birthmark off camera.”

“We’re dead, we’re dead, we’re deEEEEAAAAAAd d d d. Oh, god! Oh man, she’s good!” Marvin wheezed as he came again.

“As long as she is the only one changed by the formula, we might be able to contain it. Just remember that the stuff was designed to be passed on in her cunt juices- we’ve got to keep any other girls from licking her pussy, and we’ve got to be careful to wash before we have sex with anyone else.”

Marvin chuckled. “Yeah, like THAT’s a problem for us!”

“Thank God the formula only affects women.” Jefferson sighed. Then he got a worried look on his face. “Marvin, was your cock always that big?”

Marvin was thinking the same thing looking at Jefferson’s unit. “Maybe it was not a good idea to program the nanos to try to spread themselves” He suggested.

In another part of the city, Tom was amazed to see that his body was buffer, more toned, and that his cock was almost twice the size it had been when he was having sex with... what was her name again? It did not matter. He felt great and looked forward to a day at the office. So many women, and just one of me, he smirked to himself.

Jill woke up and stretched, giggling to herself as she hugged her increasingly jiggly boobs to her. “Good morning gals! Are we going to have fun today? Yes we are!” She reached down between her legs and felt her eager little clit. “And I’m not going to forget you either, cutie!”

She positively gloried in her own reflection. Her hair was thick and so shiny it sparkled. It was a warm gold color with all kinds of highlights and tones shooting through it. Her face was so sexy it was easy for her to imagine men melting and her lips wrapped around their cocks as they blew their minds and their loads at the same time.

Her tits were huge. They were pert, proud, puffy, protrusive, projecting, pudding-like (OK, now she was just getting silly, she giggled to herself) The clothes she bought yesterday that were snug and flirty were now proving to be skin tight and eye-poppingly sexy... those she could squish her tits into at least!

She could not ride in the heels she so desperately wanted to wear, so she wore her bike shoes with the most darling little socks! She added a couple of ankle bracelets to make up for the lack of heels.

As she rode into work, the feeling of exhilaration was still there, but this time her clit supplied it instead of the wind! She really, really liked riding her bike- it was so friendly and so helpful in poking her right -there—! She loved how her tits wobbled, and she loved the feeling of the sun on her face and chest. It was so warm on her chest. It was like her exposed titflesh was solar powered and she could feel herself charging up. She closed her eyes as she felt the warm sun soaking so deeply and warmly into...

###CRASH###

‘Oh golly!’ Jill thought, she bashed right into the rear of a parked car. A big guy climbed out of the car, rocking it on its shocks as his weight left it. Jill looked up into his angry face and all she could do was to think about how big his cock had to be. She smiled at him, licked her lips, and gave her golden hair a little shake. “I’m, like, SOOOOO sorry, sir. Are you OK?”

The man had started to build up a righteous anger, but as he caught a look at Jill’s gorgeous face and those giant tits. Dear God, he thought, look at this girl! he found himself suddenly tongue tied. To cover his embarrassment, he quickly looked at the fender and winced at the long scratched crease. “I guess there is not much damage. Are YOU alright?” He forced himself to look her over for injuries and was transfixed by her tiny waist, long, trim legs, and... was that a wet spot?

“Gee, mister, you look really shaken up. Maybe I can help relax you.” Jill guided the unresisting man to the back seat of his car. She sat him down sideways on the backseat, his feet still on the sidewalk and she pulled down his pants before he could muster much of a defense. She was delighted by the size and scent of his cock- even though it really was not that impressive. Her obvious adoration made the man feel wonderful and he was already leaking a bit. “Oh, look at that. Can’t waste that, now, can we?” and she bent to take the head of his cock deeply into her throat.

Before yesterday, Jill had only given head once and now she could not figure out why the hell not. It was so great! She slurped his cock deep in her throat, slathering it with her drool and running her tongue on every centimeter. She moaned and hummed around it and delighted in the sense of it rubbing in her mouth. She played with his balls and wrapped her fingers around any exposed shaft, as if to keep it warm.

She was gifted with a new innate talent for sex in all forms and the guy had never had such an erotic experience, and it was heightened by the fact that anyone could see them out there! He tried to hold back, but lost it all too soon.

Jill stood up and proudly showed him her load before swallowing with a grin. “There, that should be better. I’ve got to get to work now, ta!” And she peddled off. The guy struggled to his feet, looked at the dent again, and said ‘fuck it’ as he settled in his seat to replay the event in his mind over and over again.

The office was empty and a terse note told Jill to report immediately to the chemical company. Jill was feeling a touch scatterbrained and had to look up the address again before she rode over. By the time she got there, her little pussy was all juicy and her tits felt like they had grown again- how adorable, she thought. She had to look at the note she wrote herself to remember the room she was to report to, and she got a bit lost a couple times in the seemingly endless corridors.

The big-titted blond at the reception desk was not much help, but eventually Jill found the right room and was shocked to see her boss, Jack, in the room with what looked like a couple of nerds. Mmmmm, nerds, she thought. They could be fun!

“J-Jill?” Her boss stammered. The three of them were looking at her like they had never seen a woman before, which made Jill all juicy again. A few days ago, she was short and scrawny, a real Tom-boy in bike shorts with no real curves. The Jill her boss remembered had bad skin and rather nasty hair. This Jill was a walking wet dream. She was as tall as he was, and her large chest threatened to overwhelm the way-too-tight pink tank-top she was barely wearing. Her tight hot pants almost creaked with the stress of securing her bouncy bottom. And dear lord- her legs! her legs were the only nice part of her before, and now they were long pillars of toned muscle gorgeous enough to draw the eye of a conformed tit man from her chest. Jack popped a woodie so fast it hurt.

“Hiiiii, Jack!” She waved and giggled. It was fun to let guys look at her bodacious bod, and it was fun to see their pants get all nice and lumpy like his were. “And who are you two cuties?” She asked the guys staring at her from across the counter.

“I’m Jefferson and this is Melvin.” Melvin said, ignoring his partner’s harrumph. “We would like to ask you some questions if that is OK.” Melvin really did not need to even ask, he could see the signature elements of the bimbo juice in the young lady. Even her voice was like they had planned- slightly breathy, with a faint purr behind it. It sounded so erotic!

“Sure! Can I ask you some back?” She was just so perky and chipper! It was adorable and so arousing coming from such a vision. They agreed almost without thinking.

Jefferson started, wiping his glasses as he prepared. “When the shipment was damaged, did any of it get on you?”

“Oh, no. I mean, it looked like it was all in the packing thingie and did not leak. But my water bottle broke and got me all wet. I even got a cut, see?” She pulled her top off to show them the tiny scar that remained- the only blemish on her perfect skin. The three men watched her boobies settle in place before any of them could shift their attention elsewhere.

“That little scar?” asked Melvin, looking at it closely (and trying to ignore the radiant heat of her big breasts just over his head). “It looks like it is a couple weeks old and nearly healed.” She assured him that it was just a couple days old, and hurt like the dickens. She pointed out some other injuries that there were no longer any traces of.

“Huh. Well, I THOUGHT I was hurt there. I guess not. Whoopsie!” She shrugged, making her naked hooters bounce in ways that made Melvin think of advanced physics motions, made Jefferson think of unique sine waves, and made Jack think about bending her over.

“Jill, this is important. Can you tell us when you started to change and how?” Jefferson asked, clipboard at the ready.

“Changed? What do you mean? I changed my clothes this morning. Do you like them? Aren’t the shoes darling?”

Jack tried to help. “No, Jilly, you remember? You used to be short and plain. How did you get so sexy?” Jill scrunched up her face. Wasn’t she ALWAYS hot? She... she sort of remembered looking plain, but that was like a really long time ago, wasn’t it? The memories tickled.

“I... did I used to be kinda short?” She stroked her long golden hair. “And my hair was shorter... and a different color? Oh, and I didn’t have boobies, did I? Do you like my boobies?” She asked, bouncing them joyfully.

“Hummina hummina hummina” The three guys sort of went gaga for a minute watching the patterns her big old nipples made in the air.

“This isn’t helping. We already pretty much know the overall process.” Jefferson said, taking charge. The tall black man slipped his glasses in the pocket of his lab coat and went to a cabinet. When he came back he was holding a big red dildo that made Jill drool on both ends. “We need to see how far the changes have gone.” He positioned Jill on an examination table.

“Whee! Do you wanna look at my pussy?” She asked hopefully. She liked showing off her pretty pussy- it usually got fucked when she did. She quickly slipped off her panties with a wet slurping sound and put her feet up in the handy stirrups. She really liked the stirrups- they put her in a fun position!

Melvin came around to Jill’s side. “Now, Jefferson is going to place the tip of the dildo just inside your outer labia, er, your pussy’s lips. You need to see if you can pull it all the way in with just your vaginal muscles, OK?”

“Like this?” She asked, sucking the dildo all the way in in one motion. The guys stared at the eye ring at the end of the device that was the only part left visible.

“Hummina, er, I mean, yes. Now, can you push it out?” He had barely finished the sentence when the thing shot like a rocket across the room. Jill said it was fun in a giggly voice.

They washed it off and positioned it again. They had her pull it in, then partially out, and in again until she was fucking herself with it wildly- all with her vaginal muscles. The guys could barely talk watching it go in and out as if by magic and Jill cooing and purring through orgasm after orgasm.

After the guys cooled off, Jefferson posed the next test. “Can you twist it back and forth, like this.” He grabbed the eye bolt and twisted it left and right. The guys watched as the eye bolt twitched and moved back and forth a few times, then it turned clockwise a quarter turn, then a full half turn counterclockwise, then back and forth.

“Wheee, I like this!” Jill giggled. soon, it was twirling back and forth, then spinning one way, then the other. Then she added a pumping to the spin and it began to drill in and out. Jack had a flashing image of attaching a propeller to it and seeing it fly across the room just from her efforts.

The two lab guys secured Jill to the table. “For this next test, we are going to try to pull the dildo out. Don’t let us hurt you, but hold on to it as tight as you can, OK?” They secured a cable to the eye bolt and a force gauge. Jefferson pulled on the gauge with his full weight. Melvin declared that it had not budged at the 50lbs of force Jefferson put on it. Jefferson and Melvin both pulled and managed to get the scale up to 120lbs, but Jill was looking bored. Jack joined in and they got it to 200lbs before the table started to scoot across the room.

Jill was laughing by now. “Here, try it now,” she offered. She had moved it so the very tip was all that she had in her. The three men gently started to pull and were flabbergasted when she slurped the dildo back in effortlessly, pulling them off balance.

Jefferson checked off a box on the clipboard. “I think it is safe to say her vaginal development is complete.” The others nodded agreement, each thinking about what it would feel like to shove their dicks deep inside that miracle.

The testing continued for a couple more hours. She swallowed different things, demonstrated no gag reflex, demonstrated incredible flexibility and a tongue that was amazingly long and supple. They found that many of her pain triggers were modified to pleasure signals, and that she could hold her breath for a very long time. Jill gigglingly thought it was because she was storing air in her boobies.

After an especially visually arousing test, Jack could not take it anymore. He ripped off his pants and boxers and tore into Jill with no foreplay. She yelped and giggled and started to sigh as Jack pounded away in her. His eyes went wide as she started to practice some of her new tricks. As he thrust in, she thrust him out, as he pulled out, she pulled in. She started to twist her muscles on him and it felt like his cock was in a wringer. She started to rub his shaft with her internal muscles- rubbing up and down on both sides independently as he buried his face in her soft tits. He was not motorboating as much as just making primal noises- his brain was shorted out and his body was locked in a launch countdown.

Jill was yelping through several orgasms as Jack’s body began to quiver. He shot his load hard and deep, and promptly passed out, sliding bonelessly off the table.

Jefferson was in the saddle within seconds, and riding her like a bronco, one hand on her tits, the other over his head as they bucked. His recently enlarged cock slid almost all the way out before she yanked it back in over and over. When she started to spin him side to side with just her cunt muscles, he was holding on for dear life. He came and came and came, and she milked him until he felt like he was ejaculating his brains. When he collapsed, Marvin bravely moved in to fill the voids. Jill enjoyed her newest toy and played with it until it too collapsed to the ground.

“They’re no fun. They fell right over.” She giggled. The boobalicious red-head came into the room asking if everything was alright. It only took a minute for her to be licking and worshipping at Jill’s delicious pussy.

“I love you!” the red-head called out, making Jill giggle. ‘Of course she does- EVERYONE loves me’ Jill thought as she played with her new love’s hard nipples.

The three men stirred to a semblance of life. Jill quickly put them to cleaning up the mess and body fluids all over as the other girl settled to massaging Jill’s perfect little toes. The men put up no resistance to Jill’s order, even calling her ‘Mistress’ when speaking to her.

“Melvin, why are you going everything I say? Is that part of what the stuff did to me?” She wondered.

“Not really, Mistress. I am not sure why this is happening. But, you do like it, don’t you mistress? Would you like me to see if I can make it better, somehow?” Better? How could things be better, she wondered.

“Can you, like, make cocks bigger?” The nerds nodded their heads like they were going to fall off as they thought about the unintended effects of the nanos on their own cocks, and not knowing that Tom was a happy camper and the ‘big guy’ from earlier should now be called the ‘much bigger guy’. “How about making yourselves big hunky guys? Can you do that?” When they nodded more she added “So... what are you waiting for?”

The two nerds turned back to their stations as Jill took Jack and the busty receptionist... over and over until they were little more than puddles on the floor.

It was lucky for our planet that the nanos did not propagate past a set number of generations. Tom and ‘the big guy’s’ significant others got a bit more ‘developed’ before the nanos died off.

Jill, Jack, the receptionist, and the nerds, thankfully, stayed in the lab until the nanos were burned out- although that was not the intention. By the next day, the guys were almost musclebound from their development, and if they got a hard-on, there was not enough blood supply to keep the brains going so they tended to pass out after climax which made Jill sad, but by alternating them, she was kept happy.

Of course, their boss found out the next day what was going on and fired everyone’s asses (although he did secretly rehire his niece) and Jack nearly went bankrupt trying to cover his own now over-developed ass.

Jill and the nerds moved in with him so the men could serve their Mistress, their Queen, their True Love, and even got themselves jobs as ‘escorts’, strippers, and whatever they could do with their somewhat reduced IQs to bring money into their happy home.

As for Jill, she still enjoyed riding her bike. Of course, she often found that it would ‘break down’ whenever a cute guy was nearby, or she would ‘struggle’ to figure out how to carry her purchases home on it until a suitable helper arrived. After all, someone like her could hardly be expected to be satisfied by a mere three guys, could she?
