I was sitting at a computer at NYU doing study. Getting over my experience with Nina three days ago. I'm studying for a criminal psychology exam, and not noticing Nina sitting on the other end of the room

"Ok, so insanity, being normally thought as a medical term, is actually a legal term. It is a defence that is used in order to get a lighter sentence, and is proven if the psycological issues of the defendant drove their actions. If the insanity plea were to work, how would the psycology affect the crime?" I was reading the question of a practice examout loud, racking my brain for an answer. Suddenly Nina pipes up with the answer

"If the defendant was unaware of their actions being wrong, or if they don't understand the nature of their actions." I look around and see Nina across the room. "Oh hey you. Thanks." I enter the answer and Nina comes over to me

"So Sierra, I was looking at the results of our little experiment the other day." I become intrigued. "When you were under my foot, your heart rate increased big time. However, I looked at your brain patterns yesterday, and your brain was flooded with Dopamine. You enjoyed being there, didn't you?" Nina said with a sly smile

I was in shock. Nina knew my secret. "Y-You aren't wierded out are you? *gasp* you haven't told anyone right?" I was terrified, but she held her hand ul, indicating for me to stop. "Don't worry. Nobody knows and I'm not wierded out, however, I have a proposition. Though it's strange to admit, I liked having you small, and I want to do it again. I'll shrink you now, and put you in my sock. You'll stay there all day, and tonight when my parents leave for work, I'll grow you back and you can go home. This will also test your durability further."

I was skeptical. It sounded amazing, and a dream come true. But a whole day? I look down at her feet. White socks, and grey Keds. Those keds were tight, and Nina's feet would likely get sweaty. Here's the thing though, it would help Nina's experiment, it would let me live out my fantasy, and make Nina happy as well.

"Ok Nina, let's do it." She smiles, and pulls the device from her bag. I log off, and put my bag in my locker upstairs while Nina calibrates the device. When I return, Nina has her right shoe and sock off. For some reason, a knot forms in my stomach, but I ignore it. She aims the device. I take a deep breath, and the familiar feeling of nausea washes over me, but it's less jarring now. My vision clears and I'm greeted by the giant foot that squashed me just s few days earlier.

Nina looks down at me with glee, and is holding her sock above me in her right hand. She reaches her left hand down to me. I don't flinch as I'm slowly raised into the air. Nina shifts me over the opening of her sock and starts giggling in anticipation. This is a new side of her, and it kinda scares me

"3...2...hehehe...1..." Nina counts down, and drops me on 1. I land at the toe and it feels like I'm on a smelly cotton hammock. The sock begins lowering like an elevator, and five monstorous toes appear above me. No nail polish. They come at me like I'm prey, and they slam into me with the force of a bullet train. I'm forced deeper into the flesh as Nina pulls the sock tight. Again, the lowering feeling overcomes me once more, and things get dark. Nina put her shoe back on

For the next seven hours, Nina's foot becomes slowly more sweaty and smelly. It's my heaven. But thirty minutes in, I make sense of the knot I had in my stomach. When Nina studies, her right leg crosses over her left leg, and she shakes her right foot like crazy. This of course happens, as I feel like I'm on a major rollercoaster. Luckily, whatever makes me durable stops me throwing up. During the occasional periods of Nina's feet being still, I lick at her feet, cleaning the sweat off, becoming slowly more turned on. What I didn't know then, is that me worshipping Nina was turning her on as well

The hours go by and for the last two, Nina lies on her bed with her shoes kicked off, giving me a break. After Nina's parents leave, Nina goes outside and takes her sock off. "Time to grow you back. Did you enjoy yourself?" I nod aggressively. "I hope we can do it again girl." She smiles, "of course. But not for a little while." 

She sets me on the ground, and reaches for her pocket, realising the shrink ray is inside. "Sorry, I'll be right back." Nina runs back inside. I wait patiently, but before Nina comes back, I hear booming, and a hand grabs me. I try to scream but the flesh stops me. After five minutes, the hand opens, and I see the face of...
