Hey, so right now I'm in a strange situation. My name is Sierra, and up until two weeks ago I was a normal psychology major a NYU.

Two weeks ago, I had finished class and made my way to the science lab on the fourth floor. My best friend Nina wanted me to help her on some kind of project. She's also in my class but still majors in Physics

I enter the lab and see Nina standing in the middle of the room, her raven hair tied into a ponytail, and a white labcoat worn over a knee length summer dress, and white flats. Odd outfit for the lab.

"Heeey Nina. What did you want me to help on?" I asked. 

"Hello Sierra," she said with a heavy Chinese accent. "Thanks for coming by. I have a device here that's going to release an energy wave, which should multiply and compress your molecules, making you almost invincible," she babbled on

I was skeptical. "And you want to test it on me? Isn't that a little dangerous?"

"Don't worry, if it doesn't compress your molecules, it won't do anything"

Nina is my bestest friend in the world. I trust her completelty. "Ok, but if you kill me, I'll haunt you till your dying day," I giggled

Nina smirked, and aimed a silver rectangular device at me, with a blue LED on the end. She held down a button, and I was overcome with nause, causing me to almost black out. The world began to distort, but I took no notice. As my vision cleared I saw a white wall in front of me, with a leather scent coming off of it. I regained all my vision, and saw that this was in fact a flat, Nina's flat

I looked up in awe, at my now colossal best friend. She had her mouth opened wide in shock at my minute body

"NINA, WHAT HAPPENED TO ME!?"

She stuttered, "I...uh..I-I don't know. Perhaps it condensed each molecule in size, making you tiny"

I was taken aback, here I was, 2cm tall standing in front of a giant asian girl's foot. I look up, and see Nina's face turn from shock to thought. 

"Hey Sierra, do you trust me?

I look up at her, and think. She didn't intend for this to happen. "Yeah, yeah I trust you girl."

She bent down and reched her hand down for me, grasping me between her fingers and raising me slowly to her face. It was nauseating, but kinda fun, and Nina would never hurt me. She  grabbed something from the table wiith her other hand, and held it next to me. It was a near microscopic disk, and was sitting on her fingertip. 

"Stick this to your chest please." I complied, and she placed me slowly on the table while opening her laptop and making a few clicks, opening a strangge programme displaying a 3D model of a person, and some vitals. They were my normal numbers. This disk must be reading my vitals

Nina looked back down at me, visibly nervous now. "O-ok, now please lie down, and don't move. Please trust me now more than ever." I was hesitant, but I slowly lay down. If I couldn't trust her now when she's begging me to do so, I could never do it again. 

Without warning, a mound of flesh entered my field of vision with blinding speed. I t was Nina's thumb, hovering over my tiny body. I began to panick, thinking she was about to crush me, and I was kinda right.

Her thumb lowered down on me while I was screaming, paralysed with fear and I felt her warm flesh muffle me and press down, and I thought I was going to die, but realised something. There was pressure sure, and it was uncomfortable, but not painful. I was relieved. 

Nina lifted her humb off of me. "I knew it. So, I kinda succeeded Sierra. Yes, you're tiny, but you're extremely dense. Each molecule is compressed instead of the molecules as a whole being compressed together. So your weight hasn't changed, but your density, and I guess your size, have changed."

I didn't understand alot of what she said but nodded like I did, the same thing I normally do when Nina starts babbling about physics

"I want to test your limits. Is that ok?'

I just survived her thumb, and I wanted to enjoy this while it lasted, so I agreed. She placed me back on the floor in front of her feet

"So I'm going to step on you, but my shoes will probably be painful so I'll use my bare feet. Sorry if they stink, hehe"

I didn't let it show, but I was ecstatic. I know how awkward Nina can be so I never told her about my foot fetish, or shrinking fetish, which only then set in was coming true. She pried her feet from her flats using her hands, and pushed her flats out of the way. Her feet were pale, and had a slight odor that turned me on right away. Her nails were unpainted. 

"Here we go Sierra. If the computer alerts me I'll lift my foot off. Just shout if it's too much, and the computer will tell me." Her right foot rose off the ground and moved over me. Her sole was caked in sweat, which turned me on even more. It lowered slowly on top of me and I lay down with a huge smile on my face. The sole made contact and I was in heaven. It started pressing down, and despite the shoe being off, it was stil kinda painful, however, I refused to scream. I wanted this to last as long as possible

For about two minutes, I was in bliss, and suddenly the foot came off, I was kinda dissappointed. "The computer said your heart rate was raising way neyond normal. Are you ok Sierra?

"Yeah Nina, I'm great"

She smiled. "Ok, just one more test. It's going to be unpleasent, and most likely painful, but after the last two tests, I'm sure you'll be ok." She picked me up, not waiting for a response this time. She held me in front of her huge lips, painted a vibrant velvet red, and her lips parted. I then knew what she was doing. 

While I had masturbated over this scenario, I never considered it happening for real, and at this point I was pretty nervous. She brought me towards her mouth and forced me inside, placing me onto her tongue. She closed her mouth, ancasing me in moist hot darkness. It was very scary. I felt myself being moved to the left, and felt he surface below me change from a moist muscle, to a moist hard rock like surface. It was too late when it struck me what was hapening, and a similar feeling surface came from above, and I felt the worst pain imaginable. After a few seconds I screamed, "NINA STOP! IT'S TO MUCH!"

I was shot out of her mouth by a sudden force, and I was overcome by blinding light and I felt the ground below me change into skin. Nina spat me onto her palm. "I'm sorry Sierra. That was probably too far." I calmed down and became less afraid and angry

"It's ok. Did I taste good at least?" I asked with a smile

Nina laughed, "you were delicious, but let's get you back to normal size now. I have enough data."

She lowered me back to the ground, and aimed the device back at me. The nauseating feeling came back, and as my vision returned, I saw Nina, still standing tall at 5'7", a whole foot taller than me, but not giant anymore. I picked up my purse, hugged Nina goodbye, and left the lab, planning to masturbate later over this wonderful experience

What I didn't know at the time, was that this was only the beginning...
