You are a dark red-haired, white 17 year old girl with blue eyes who is only 5'3, and your boyfriend, Alex, teases you about your height despite you only being an inch under average, he calls you Mini. One morning you found a box on your porch, inside of which there was a strange gun like object. Upon reading the letter in the box you realize it's a ray that can shrink and grow things and make them invincible. You decide it's payback time...

Your boyfriend has always called you Mini, even when you aren't really that short, but Alex always says that you're short to all 6' of him. You decide to surprise him slowly though, you set the gun to grow something by 4" and shoot it at yourself before school, you notice that the gun had greatly reduced any small bits of extra fat you had replacing it with toned muscle. Now that it's time to get ready for school you decide to put a pair of black leggings on and a t-shirt today, however the shirt used to cover up half of your butt, but today it didn't do so at all, not to mention the full length leggings were about a quarter of the way up your calf. You just rolled with it though as you managed to fit into some shoes and went off to school.

Upon arriving you are greeted by your best friend, the blonde, fit 17 year old bombshell Lauren, she was 5'5, taller than you or well normally taller than you. Upon seeing you she said "Oh my god! What happened to you? How are you so fit all of a sudden? How are you taller than me?!"

"Shh!" you respond "You know how Alex always calls me Mini? Well I got this device that can change the sizes of things, so I decided I was going to go and give Alex a slow surprise"

Lauren asks you to let her in on it too as she always wanted to be tall, and to be fair she did have a body more suited to a tall person, you agree to grow her. You set the gun and shoot it at her, she grows 4" to 5'9. Seeing her grow made you want to do so again, so you scrap the idea of making it a surprise over the next couple days and continue to grow Lauren first. You decide to top her off at 8" more, leaving her at 6'5 and looking fitter and stronger than ever before. Now it was your turn, you aim the gun at yourself once more and pull the trigger, you hold down the gun long enough so that you become 17" taller topping off now at an impressive 7'3 of a toned, stronger, and fitter version of yourself. Realizing your both your clothes were strained beyond the limit you both undress in the handicap stall in the bathroom, and you shoot the clothes which works much to your relief, though this is harder than you thought so the clothes fit you both better now, but are still a little bit tight.

You both arrived at school early and had your first class together with your boyfriend as well, you all sat at the same table. Alex usually arrived early too, but not as early as you two did; so you both decide to head to your classroom which your teacher is currently way from, probably getting coffee, and sit down at your seats at your table waiting for Alex. After about five minutes Alex walked into the class only finding you two, he had a perplexed look on his face and asked "You two really look different today, how come?" Alex continued right away blushing to catch himself "N-not in a bad way! You two actually look really really good different! I just can't figure out exactly why!"

You and Lauren both giggle at how cute Alex looks blushing and stumbling over what he said; for as tall as he is and as confident as he is, he is also strangely timid just talking to girls, not as much to you but still he is a little timid towards you once in awhile. "Lauren why don't you be a dear and show little Alex here why he's the new Mini?" You ask your best friend who replies with a smile saying "It would be my pleasure! Alex please step over here closer to my desk" Alex complies even more confused as to what is going on, when he arrives closer to her desk Lauren begins to slowly rise out of it. She's going up and up and up at a very slow pace, when she reaches where he normal height would Alex is surprised to see her continue to rise, even more surprised when she reached his eye level and still continued to rise, and he was dumbfounded when she stopped rising and he was looking up at her, whereas her eyes made contact with the air about an inch over his head, if he looked straight on he made eye contact with the area about an inch under her chin. The top of his head now only reached the tip of her nose. Alex just stood there speechless, silence filled the room for a few seconds which felt like an eternity, that is until you broke it when you said "Alex, honey come over here, you haven't seen anything yet!" Alex was currently feeling a mix of emotions overtake him, but most of them were good, he thought this was amazing so he walked over to your desk. Sitting down you are looking up to him still obviously, but you slowly begin to rise, first to your old height, then to his height making eye contact with him, then to Lauren's height for the first time seeing the space above his head, then to your full 7' of height. Alex's eyes come to where your breasts start, the top of his head reaches the tops of your shoulders, you and him both love this feeling, the feeling of him looking up at you. "Who's Mini now?" you ask him.

Alex's personality was quite the mixed bag, he now felt like his pride was being challenged, he said "I might be shorter now, but surely I am still stronger!" Hearing this from him doesn't really surprise you, but still irks you nonetheless, "Fine then if you're so sure why don't we have a little contest to see which one of us can do more push-ups?" Having received an actual challenge Alex is quick to accept, Alex gets in position first and begins, Alex finally collapses after doing an impressive 225 push-ups. Now it is your turn, normally you wouldn't even stand a chance as you probably couldn't even break 20, but even though you haven't tested your new body yet you feel like you can do anything, you get into position and begin. You're doing the exercise extremely fast with a perfect form, it isn't long before you reach 100 then 200, at which point you feel some fatigue develop, but not much you continue until you hit 450 finally not being able to continue. "OK so you might be stronger than me too" Alex said, clinging onto some hope he continues "But surely Lauren isn't I mean she is closer to my size after all". With that Lauren decides to join in on the fun, gets into position, and begins; while not as quick as you she was quick, she got to 100, then 200, and at 225 she acted like she was about to stop, and Alex hope she did, he fell for it, much to his dismay she continued, though she as legitimately fatigued just not that much, in fact even less than you felt at that point, she continued all the way to 500 push-ups before collapsing. Upon getting up Lauren said she had an idea, which was for you three to flex and see who had the biggest arms, Alex went along with now past the point of caring at all, he flexed his 14" biceps, next you flexed yours which were probably about the same size because they were spread over a much longer arm, then Lauren flexed and her bicep engulfed both of yours, hers was 16" and spread over an arm longer than Alex's and not much shorter than yours. It was clear who the strongest was, Lauren said "And look at what else happened too Alex!" Upon saying that she grabbed your shirt and hers and lifted them to reveal two very well defined 6 packs, however hers was a little more chiseled than yours, probably due to her having worked out more previously so you couldn't really complain.

Alex now looked more defeated than ever, and while you liked being much taller than him it did feel awkward to be like that now, upon feeling this way you say to him "Alex, I think you're to small to date me now." Alex is shocked by this "What do you mean, are we going to break up now?" he asks you. "No, not unless you want to," you reply " I, however, was thinking that we fix this size discrepancy." Alex is now looking very perplexed by what you are saying and asks "What do you mean?"

You have Alex follow you and Lauren into a store room you know of in the school that no one ever goes in to. You begin by explaining to him how you and Lauren got so big, and then you say to him "You're too small, well right now you are, I did in fact like being smaller than you, just not the names that came with it, so if you promise no more small names for me, I'll let you catch up to us and then some." Alex enthusiastically agrees, however, this time to make it easier you have him strip for your and Lauren's enjoyment as well. You begin firing the gun at him, you set the gun so it goes slower this time, about 1/2" a second, he slowly rises up and as he does he gets bigger all over. His muscles begin to increase in size and become more toned, by the time he reached your height at 7' it was evident who the new strongest was, but you still continued, slowly but surely he rose and rose, eventually passing 8' in height, eventually stopping at 9'. you made him much taller than yourself, so now you and Lauren could give him a show.
