"But Princess Celestia, I want to study magic." Twilight furrowed her brow. Wasn't this the reason that she was the prized pupil of the naturally magically inclined alicorn that stood before her.
"I understand how you feel" Celestia said. "Studying magic is dangerous and you already spend so much of your time researching it." Celestia made her way over to Twilight and placed a hoof on her shoulder. "I just think a little bit of time spent studying some different subjects would be good for you."
"I like learning about other things, but why do I have to go all the way to Manehattan to do so?"
"Oh Twilight, I have enjoyed being your tutor. Regrettably there are many things you have yet to learn that I cannot teach you." Both of the ponies made their way to one of the castle's large windows. Outside the sun was beginning it's descent. Soon the land would be cast in the red and orange light of sunset. "I suspect once you get there you will enjoy attending college. Just think of it, being on your own for the first time. Learning from ponies near the top of their field in knowledge. Spending time with ponies your own age."
Twilight thought for a moment. It would be nice to learn about some other things. She could stand to be a little more independent. There were already lots of ponies her own age here in Canterlot but she spent very little of her time interacting with them preferring to spend her time studying instead.
"Everything will be fine, you'll see. Go and finish packing your things. The train for Manehattan leaves early and you'll want to get plenty of sleep for your journey."

Manehattan University was only a short walk from the train station and Twilight found herself surprised by the size of the structure. "It's almost as big as the castle" Twilight said to herself marveling at it. Various ponies of every race and color were milling around the campus and interacting.
Twilight pulled her luggage close to her and swallowed nervously. "OK, you can do this." Twilight made her way into the building and noticed some signs pointing her toward the admissions office.
When she arrived there she saw a unicorn with an orange cream coat and white mane sitting behind a desk and going over some forms.
"Um hello, my name is Twilight Sparkle and I'm here to attend classes" Twilight said blushing a little.
"Aww, no need to be shy. Welcome to Manehattan University. My name is Orange Creamsicle. Let me see if I can find your file." Orange Creamsicle went through some files and pulled one out. Opening the file she instructed Twilight to sign one of the forms and hoofed over a class schedule and room key. "You're in dormitory 302. Classes start tomorrow so take today to get settled in. If you run into any problems just contact a member of the staff, we'll do whatever we can to assist you. Have a wonderful day, Twilight."
Twilight smiled and thanked Orange Creamsicle for her help before heading in the direction of the dormitories. Once she arrived she had little difficulty locating her room. Unlocking the door, Twilight stepped inside and took in the sparse but pleasant furnishings. Her dorm room contained two beds and two desks with a window facing east. A doorway led to a bathroom with a toilet, shower, sink and wastebasket. "Guess I'll be eating my meals in the cafeteria" Twilight mused to herself.
Feeling a little stressed from her journey, Twilight climbed onto her bed and laid down for a moment. Sighing contentedly she settled in and made herself comfortable. Suddenly, Twilight could feel a twinge from her bladder letting her know that she would have to empty it soon. A thought crossed her mind as she lowered a hoof to touch her marehood. She stood up and climbed down from her bed and made her way over to her luggage.
Opening her luggage she reached deep inside and pulled out a crinkly plastic package. On the front of the package was written 'Silly Fillies overnight training pants.' Unable to keep from smiling she tore open the package along it's perforation exposing it's contents, a stack of padded undergarments. Pulling one of the briefs from the package she held it up to her muzzle. Twilight breathed in deeply trying to take in as much of it's subtle plastic scent as she could. Holding the undergarment between her hooves she teased herself with it's fluffy softness before finally pulling it open and stepping into it. Twilight pulled the training pants up slowly feeling them brush against her fur until they were all the way on. Reaching behind she pulled the tail tab away from it's velcro fastener with a satisfying scratching sound before moving her tail into position and reapplying it.
Satisfied that the garment was in place Twilight gave her flank a little shake relishing in the sound of swishing, crinkling plastic. Giggling in delight, she bounded back over to her bed and leaped onto it sending the sheets flying in every direction. Once her sheets had settled she could feel an almost magnetic attraction between her forehoof and the crinkly plastic garment that she could no longer resist. Bringing her hoof down, Twilight began kneading the material into her marehood while biting her lower lip to suppress a passionate moan. Twilight could feel a fire building inside her and ceased her rubbing so she could cool off for a moment. Still feeling pent up, Twilight relaxed and stretched out as much as she could. Feeling the continuing pressure in her bladder she tried to relax further without straining. As Twilight felt herself moving closer and closer to release her head grew foggy with arousal and she felt herself heating up in anticipation.
When the dam finally broke, Twilight felt like a lightning bolt was passing through her. Warm wetness could be felt against her marehood as she started peeing. Her training pants started to swell as they absorbed the cascade of urine directed at them. Hot streams that were too much for the training pants to handle ran off, soaking into her fur and causing the nerves in her skin to buzz with excitement. After what felt like an eternity the pressure on her bladder subsided and the last of her pee trickled out into her training pants leaving them hot, yellow, and swollen.
Reaching a hoof down once more, Twilight worked the moistened material into her marehood again making a soft squishing sound. Warm piss was forced out of her padding and into her fur. She began digging in deep and mashing the padding now soaked both in urine and her arousal into her marehood. Twilight began to feel sparks moving through her as she continued. No longer able to suppress her passion Twilight began to moan audibly as she started to reach her peak. Her hips grinded into her hoof as small amounts of urine dripped from her training pants into the bedding below. Once Twilight reached her peak the pleasure was almost blinding. Her whole body thrashed with passion and she cried out unable to stop herself.
As she laid there entirely spent she could feel the warmth still pooled there against her marehood. Turning over on her side, Twilight felt herself drifting off to sleep as her nethers twitched from the stimulation.
