As much as you loved the thrill of being with Stacy, you had to break it off. The last straw was finding her rummaging through your research papers after she had forced your briefcase open.
"I couldn't help it!" she whined. "You never talk about your work and working is all you've been doing! I just wanted to see if it was almost done!"
"I told you, this is very secret, sensitive government information. The fact that I trusted you with the details of what my team is even working on should be enough for you!" You rubbed the sides of your head, a slight headache forming. Stacy fidgeted at being scolded before finding her spine.
"You're my boyfriend! Of course you should be able to tell me all about this! You should be proud of your work! I want you to open up about it! I want to see what you've been working on!" Her domineering attitude always surfaced when she was confronted.
"No. You're way too invested in this Stacy. You need to pack up whatever stuff you brought over since you've been staying here and go. I cant have you around when the project starts practical testing on monday." Her ears perked up.
"So it's almost done then?" She asked, trying to get info out of you.
"GET OUT!" You grabbed a handful of her stuff and pushed it into her arms ushering her out the door.
Stacy's mind was racing as she walked back to her car, hands full of personal items from her now ex's apartment. She was trying to collect her thoughts and formulate a plan. 'The device is almost done.' She thought to herself, starting to make a bullet point list of what to do next with what information she had. 'I have a spare key to Brad's apartment that he doesn't know I made. I copied his keycard for the lab, but I don't know if that's enough to get me in. Even if i do get my hands on it, I don't know how to work it since he caught me while I was still trying to make heads or tails of the schematics. 'I think I only have one shot at this and I need to act fast.' Stacy thought to herself. She opened her trunk and threw all her junk into it before speeding off towards the lab.
Stacy sat in her car in the parking lot of the lab, trying to manifest the will to enact her master plan. She took a deep breath before leaving the car to stride towards the lab. Her strides weren't very long. She was only five foot four in her heels that made a loud clack against the pavement. Her small breasts didn't so much as jiggle in her sports bra as she powerwalked to the door. Another deep breath and she was ready. 'Here goes everything.' She thought to herself before flashing her ex's badge over the reader. It turned green and the door lock clicked. She was in.
Meanwhile, you were trying to put all of your notes back together. You quickly realized that your keycard was missing. "Fuck!" You cursed out loud, realizing that she must be on her way to the lab. Knowing that phones don't work once you're in the building, you grabbed your keys so you could warn your coworkers who were hopefully in the building. You sped after your ex, hoping it wasn't too late.
Stacy confidently walked through the foyer past the empty front desk and into the lab area. She was trying to strut about the place as if she belonged there, but her heart rate was spiking. She reached the lab and finally laid eyes on the device for the first time. It sat in a glass case, the designated name GRP-MK1 on a little title card next to it. 'This is it!' She thought to herself, salivating at the thought of getting her hands on her prize. 'The Growth Ray Prototype Mark One.' She reached her hands out towards it.
"Hey, you can't be in here!" A male voice called out. She recognized it. It was your coworker Shawn. 'Shit shit shit shit shit!" She thought, before turning around and beaming the biggest, fakest smile she could muster.
"Shawn!" She exclaimed warmly, trying to act as if nothing was amiss.
"Stacy, what are you doing here?" He said puzzled. "You shouldn't be in here. "Where's Brad?"
"I thought he was here!" She said innocently. "He gave me his keycard and told me to bring him lunch so we could have a little date before he had to go back to work." She made big puppy eyes at her ex's coworker. "Maybe he forgot about me. He always seems to be forgetting about me. Do you think he could be cheating on me Shawn?" She started to force tears to well up in her eyes, forcing a wave of empathy to wash over the man that could make or break this whole operation.
"He said he was so excited to show me the first stages of the practical testing too!" She made sure to use the same terminology that Brad has used so Shawn would think she came by this information in a morally acceptable way.
"Well..." Shawn started, "I don't think he's cheating on you Stace. He talks you up all the time. You're his little firecracker of a girlfriend." She bristled at the word 'little' but tried not to show it. "Maybe he gave you the wrong day? Practical testing isn't supposed to start until tomorrow. Today is Sunday. There's no one here but me, and I'm just going over all the specifics so that everything will be ready by then."
Her eyes lit up with all this new information. Knowing it was just her and him, her demeanor shifted. "That's really too bad." She pouted, walking over to Shawn. "I really really wanted to see the device work. Stupid Brad was so excited to show me that he gave me the wrong day. And I'm busy tomorrow, so I'll never get another chance to see it. After he talked it up so much to me and everything.."
"I'm sorry Stacy. I wish there was something I could do to help." She gave him her best pleading face at this point.
"Well it's ready isn't it? Can't you just give me a teensy demonstration? Pretty please? No one has to know." She put her hand on his chest now. "Besides, don't you want to see that it works before tomorrow? I would hate for you to be doing all this work alone tonight and for something to not work tomorrow. They could blame you." He immediately saw her point.
"Well...I was going to say no and kick you out of here since you don't have any kind of clearance, but its nice to talk to a girl once in a while. You're right though, I should make sure it's calibrated correctly and ready for the real demonstration tomorrow. Just sit right over there behind the blast shield and I'll get it all set up. You're in for a treat." Shawn's ego began to flare and he was getting excited about showing this little cutie what they've been working on. 'Sure she's Brad's girl, but he isn't here.' He thought.
He grabbed an apple from the break room and brought it back to the lab. Stacy was sitting right where he told her to like a good listener. He set the apple on a pedestal. He than carefully picked up the GRP. He fiddled with the settings far away enough from Stacy where she couldn't see what he was doing. She cursed under her breath. "Almost ready?" She said in her cutesiest voice.
"Ya, we're there." Shawn replied. "Standby." He lowered his safety goggles a and walked back behind a line that was a certain distance away from the apple. "Ok. We're recording. On my mark in three, two, one. Engage." He fired a soft green light from the gun that hit the apple spot on. Once it found its mark, the beam locked and began to pulse into it. Stacy watched in awe as each pulse caused the apple to in turn pulse larger. It trippled in size in a matter of thirty seconds. She could feel a wet spot forming between her legs wishing that she could trade places with that apple. "Disengage in three, two, one. Power off." He switched the gun to off and the beam thinned and ended its connection to the hulking fruit.
"Is it safe to come over there now?" You said, not even trying to hide your manic excitement. He nodded and you quickly walked over to him. "That was incredible! It works even better than Brad said it would! I bet that's because you were the last one working on it! You're such a genius! And a stud!" Shawn was blushing now. He cleared his throat.
"Yes...well that was what you wanted to see and all I needed to test before tomorrow. I hope you're satisfied now." He began to put the gun back where it went.
"Wait!" She blurted, louder and more desperate than she intended. Shawn was taken aback. "I mean..." She said mousily. "Did it work? I can tell it looks bigger, but is it safe? Is it gonna blow up or something? Is that as big as you meant to make it? Can you make it small again? Sorry, I'm kind of dumb and don't really understand how it works or any of the science behind it. Could a smart guy like you make me feel at ease and explain it to a silly girl like me?" Shawn's ego flared again.
He held the device in his hands and turned to face her, delaying the return of the ray to its home. "That's a lot of questions for someone who isn't even supposed to be here." He paused. "Hell you seem just as interested in this stuff as your boyfriend. But I'm in such a good mood after the test worked, what the hell. First off, it worked just like it was supposed to. We had done the calibrations for this specific fruit with the hopes that the energy input over the time we alloted for would result in about a three times gain in overall mass. It looks like we've achieved that. Secondly, it's totally safe. All this GRP has done is deliver the proper nutrients and signals to tell the apple to 'grow' in a sense. The ray signals the cells in the organic material to accept the nutrients in the beam, get absorbed, and the cells then go through forced mitosis. The longer the beam stays on the organic matter, the longer the cells continue to go through the multiplication. So healthy cells make more healthy cells and result in growth. There are settings to localize the beam on different parts of the organic matter, so like you can make a giant banana without having a peel that's thicker than tree bark. It's just all in the settings." He seems so proud of his work. "Oh, and no, we can't shrink it down. We haven't worked even a little on the hypothesis of sucking the nutrients back out. Once it's big, it's big. Which is good for what we need it for." She liked that answer.
While her mind was racing with all the new information that had just been mansplained to her, Shawn twirled the raygun around like a six-shooter and pretended to fire a shot at Stacy before blowing on the tip, mimicking a cowboy in an old western. She opened her arms wide as if pretending (hoping) to be shot. Shawn just stared her down and gave her a puzzled look. "I wasn't gonna use it on you, Stace. Don't worry." Worry was the last thing on her mind as she gave a nervous giggle in reply.
"I know that. Of course you're not. You wouldn't want me to become more woman than you could handle." She batted her eyelashes at him and gave another silly giggle. "But..." She pressed on, "...what would have happened if you did?"
"Well trials on animals don't start for another few months at least. I mean, I've been tinkering with the settings for it sure, but we'd have to start with like bugs and mice and stuff first." Stacy stuck out her bottom lip.
"And here I thought you could help me get a little bit...bigger." She said accentuating the last word as she stuck out her tiny chest towards Shawn. "How about just a teensy bit? I could be the perfect test subject. I'm right here and I'm ready and we don't have to tell anybody. You said the apple was safe and you've been fiddling with the settings for animals. I'm an animal Shawn. Shoot me. Show me what that big brain of yours can do with that gun you've got there. Pretty please?" She laced her fingers together and pleaded her best.
"I guess it couldn't hurt." Shawn replied nervously. "I know it'll work and as long as I'm only growing you the smallest bit, no one should know. Stacy squealed with delight as she skipped over to the pedestal the apple was resting on. She picked it up with both hands and hefted it's weight a few times before gingerly setting it down and taking its place in the blast zone. She kicked her feet back and forth like am excited school girl while Shawn fiddled with the settings.
Meanwhile, you were tearing up the road doing eighty-five trying to get to the lab as quickly as possible. You had finally pulled up as Shawn had finished dialing in the machine.
"Alright, I've set it to all the proper specifications. It should work just fine on you and it should only add an inch. Two at the most. Are you ready?" Shawn seemed overconfident in his abilities, but after growing the fruit and also being spurred on by this small cutie in front of him, he couldn't not be.
"You have no idea." She replied, feeling the arousal flood her body at the prospect of finally getting to grow. "Hit me!" She demanded, opening her arms wide like before.
"Standby." Shawn began. "We're recording. First animal subject. Set for twenty seconds at one to two inches. On my mark in three, two, one. Engage." Pulling the trigger, the beam shot out and hit Stacy square in the chest. Immediately her whole body was flooded with an intense euphoria as each cell drank in the nutrients and received the signal to divide and multiply. 'Fuck. It's happening! It's really happening! I feel it!' Her whole body felt hot. Every nerve vibrating with pleasure, every neuron screaming for more. Her time was almost out though. She was too lost in the pleasure to hear Shawn counting down. "Disengage in three, two on-" just then you threw open the door to the lab after using the backup access panel to get in.
"Shawn, what the fuck are you doing?!" You screamed. Shawn meanwhile was focused on you now and failed to switch off the device after the alloted time. Stacy squirmed in pleasure as she felt her clothing grow tight against her expanding body. She tried as hard as she could not to moan or cry out or draw any attention to herself so she could grow as long as possible.
"I can explain! I wanted to make sure that everything was ready for the demonstration tomorrow so I was going to try it out and then your girl wanted me to make her a little bigger and
.." Shawn returned his focus to Stacy now, who has been basking in the beam for upwards of a minute by now. "Disengage!" He said frantically as he turned off the beam.
Stacy was taking up a considerable amount more of the pedestal than before. Even sitting, you could tell that your ex had grown substantially. "Mmmmph. Thanks Shawn. That was incredible. Even better than I could have imagined. She stood up and the seams on her jeans split. "Fuck that's hot. I outgrew my damn pants. Oh hi Brad." She said nonchalant as she strutted with her new, longer legs over to Shawn. She had grow. About a whole foot and was now slightly taller than the man holding the gun. "What do you think?" She asked, giving him a little twirl.
"I think I messed up and made you too big. I'm sorry! You only wanted to be a teensy bit bigger and now you're taller your boyfriend." He looked so small and pitiful to her while apologizing.
"Who, him?" She gestured over to you. "Oh he broke up with me earlier today. I'm actually single now if you think you can handle all this, big boy." She was still incredibly aroused, but she wanted so much more. "Oh and don't worry about holding down the trigger for longer on accident. I think that was for the best. After all, I'm not done. I want you to turn it up and hit me again."
"Stacy, what are you-" you began, but she quickly cut you off.
"Shut the fuck up Brad. I've been waiting years for this little project of yours to finally become a reality. I've always dreamed about becoming bigger. I've fantasized about it since I was a little girl. And up until now I've never felt like anything more than a little girl and certainly never been treated as anything more than such. But now you've finally helped me become so much more! Too bad we aren't together anymore though. Truly. This new body of mine feels like it could have really given you a good time. Growing has really turned me on!" She rubbed her hand over the remains of her denims before tearing them away to reavel the tightest soaked pair of pink panties, holding on for dear life. She then turned her attention back to Shawn. "Now Shawn, I'm not going to tell you again. Hit me." She took another step closer to him as he tried to back away but found himself cornered against a wall of the lab. Stacy struck like a snake and placed her hand over Shawn's on the gun. She placed the nozzle straight against her top, which could barely contain her still hardly sizable bust, and squeezed his hand against the trigger.
The beam shot out directly into her chest as the pleasure exploded once more through her cells. "Mmmph! Yes! There it is again! I don't have to hold back about how fucking good this feels now!" She let out a loud moan as the growth resumed. Panting and pressing against Shawn, she humped the air as her cells responded to the beam. You ran over to try and break the connection, but Stacy was too strong now. In her euphoric state, adrenaline surging through her, she kicked you clear across the room, knocking the air out of your lungs. As she lifted her leg to send you flying, her panties tore away, utterly defeated by her growing hips.
At eight feet, the pleasure had finally built up to be too much. Stacy released her grasp on the ray and fell backwards, spasming in orgasmic bliss as the beam was finally shut off from Shawn. She topped out at nine feet tall, taking up a significant amount of the floor as she came down from her high. Meanwhile you looked on from the other side of the room as your ex lover shook and cooed at her own magnificence.
This was your one chance you thought to yourself. "Shawn!" You croaked with what little air remained in your lungs. He broke away from his fixation on the post climax giant before him to look at his floored coworker. You made a key turning gesture towards him to signal him to lock the device away. He quickly turned away from Stacy and made a dash for the case. As soon as she realized what was happening and shot to her feet.
"No!" She screamed, lunging after Shawn as he shut and locked the device away inside a metal gun safe. "Open it! I'm not finished!" She roared trying to intimidate Shawn with her sheer magnitude.
"No way!" Shawn said, clearly oblivious to the predicament that you were both currently in. "We outnumber you two to one, and now that the GRP is safely locked away, we wont let you get any bigger than you already are! Look at you! You're like ten feet tall!"
"I know! Stacy bellowed with glee, "It's amazing! I feel so so good! No more 'little firecracker.' No more submissive pixie girlfriend. No more shy reserved daughter." She swung her arm into Shawn then as you were finally gaining the ability to breathe again. He only flew a few feet, but he hit the ground with a hard thud. As you began to crawl towards her, she put both of her arms on the gun safe, violently pulling at the handle to no avail. Then she spotted you.
"Help me open this, wont you honey?" She said, feigning sweetness. She picked you up with two hands by the back of your shirt and pressed your face against the cold steel front of the safe. She put her face right next to your ear as she whispered. "Don't make me make you. You know I can."
You felt her big strong hand pressing into your back. You knew she was strong enough to break you at this point. You were cursing Shawn under your breath for letting things get this out of hand. You were cursing yourself for letting her trick you out of your keycard in the first place. She increased the pressure against your back again in an attempt to force you into compliance. And then you did. "Ok." you muttered, defeated. You pressed the code into the safe and the light on it turned from red to green as you heard the lock click open. Stacy tossed you aside like rubbish and then opened the safe. Now, for the first time, she held the gun solely in her hands. You and Shawn were both struggling to get back on your feet as the mini giantess fussed with the settings.
"It's really intuitive once you get into it." She said out loud as she started turning all the dials way up past their recommended limits. "It does help that I got to skim through your notes honey." She smirked, looking down at you. She was getting aroused again at how much further she would be looking down at you very shortly. "And adjust this for my tits. This for my muscle mass. This for...well all of me. Setting the timer to automatically shut off after...never." She giggled as she rigged the gun to never stop after it was switched on. "Now I just set it up here out of the boys' reach aaaaand." She got into position and flipped the switch. Immediately the whole room glowed with the brightness emanating from the gun as it funneled an otherworldly amount of energy directly into Stacy's chest.
Her whole body burned in an inferno of pleasure as her cells struggled to take in the nutrients and information from the beam. "Aaaah, it feels so good! Fuck! I feel like my each of my cells is getting themselves off to this fucking feeling! All of her muscles contracted as the cells drank in enough energy to burst. Her whole body glowed the color of the beam as she felt her orgasm start to build. Then, in recognition of the beams orders, all her cells started to multiply at an exponential rate. Her body doubled to twenty feet as she doubled over to not break though the roof. Then she doubled again, lifting the gun and cradling it in her hand as she destroyed the building that previously caged her. Shawn was crushed by the debris, but a steel girder protected you as the sides of the building collapsed around you. All you could see was smoke and falling rubble, but your ears were ringing with the laughter and moans of your power-drunk ex girlfriend.
"More more more! She screamed as she stood up to her full height of 50 feet, the GRP shooting out from her hands at her as she held it gingerly away from herself. She doubled again to one hundred feet and took a few steps in the opposite direction from where you were trapped, crushing everything underfoot. 'She doesn't even feel the lives she's taking' You thought to yourself as your manic pixie giant doubled again.
"Bigger!" She cried as she doubled again to two-hundred feet now before the gun sputtered out and stopped. Dropping the gun and then dropping on her ass, Stacy began to vigorously touch herself, making sure to relish in the pleasure of her new size before the euphoria wore off. She cupped her finally stable breasts, squirming and moaning as her juices flooded the crushed city in front of her.
Finally coming back to reality, Stacy looked around. "Oh boyfriend!" She called out lovingly. "Where are you? I need you to make me another one of those rayguns because that one broke. I'm still not done!" She gave a giant pout before looking at the rubble, picking you out of it, and bringing you close to her face. "You don't have a problem with that, right dear? Not that you have a choice either."
