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 jangling 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 giggled at the thought that maybe 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 all of 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?
