Could make a fireball as big as the sun?

The questions pops into your head the instant you touch the magic pooling inside you.

It seems like a perfectly reasonable question demands a empirical answer. Your magic rushing into your right hand as you raise it to face your palm upwards. A spark of light is followed by a sphere of fire whipping out at the air around it in anticipation of it usage.

Your magic floods into the sphere with glee after days of no use. The sphere keeps growing as you feel the warmth on your face. Raising your hand above your head it keeps growing Soon the handheld fire ball is as large as your head, then larger than you. Around you the low light from sun rise is burned away. The new sun growing in your palm brighter than even the midday sun as it keeps growing. Your magic coats your skin to keep you alive.

The light illuminates the sleeve of your out stretched hand. Singed fabric that nearing ignition snaps you back with a simple observation. You don't have a replacement for this uniform since Anastasia has taken your other one. The benignity of that observation lets you stem the flow of magic. Your fireball's growth halted at half the height of the Dorm building you are walking past.

You pull the magic back inside you. The fire ball shrinking slower than it had grown. The magic returning to you held some of the heat it was fueling. As the ball returned to the size of your head it was as if your blood was hotter in your arm than every other part of you, your heart feeling warm as the blood was pumped around your body. When the ball was reduce to a flicking light you shook your hand to extinguish it.

That was a little disconcerting. You aren't sure it is a good idea but you feel your magic again, worried that had just burned off the progress you had made. It feels as excited as it had on the first day but no question in need of testing pops into your head so you think that is a good think. Your pause had given your heart time to pump your blood, your entire body was feeling your warmed blood and with it a sudden need to be active. You jogged towards the training ground in case a lack of activity would lead to another question.

When you arrive you see Stephanie waiting for you with sword and dagger drawn. She eyes you for a moment before sheathing her blades. She doesn't make any comment likely to avoid any possible antagonism.

"Sorry, I just touched my magic to see how it was recovering and, it seemed like a good idea." You say looking at you singed sleeve. Thankfully aside from being a bit darker than your other one it didn't look that bad.

She nodded at you and took off her belt resting her sword and dagger on the ground. "Copy my movements." She turned away from you and took a familiar pose. Just like yesterday she ran you through various stretches. Unlike yesterday she didn't remain as a visual guide. When you were supposed to bend yourself forward she came over and put her hand on your upper and lower back holding your position.

"Outbursts can happen if you have constant heavy usage of magic. The sudden lack of use makes the magic rebel at being held under control."

As she speaks you remember your other tutors mentioning similar things. Since it had never happened to you, you had assumed they were exaggerating. "Sorry." You said it as much to your past tutors as to her.

She takes her hands off you and you stand up. She hold her arms out to her side and your copy her movements. "If you can't do this just hold as much of the pose as you can." She raises her arms above her head and rolls her spine backwards.

As she goes you are careful to not stare at her chest momentarily thrust out. She keeps falling backwards until her arms are on the ground. You think she is done for a moment when she lifts one leg. From resting on the ground to held straight above her. Again you resist looking at the point her legs meet, suddenly very observable.

After a pause she kicks the foot on the ground and transitions to a handstand. The physicality isn't as impressive as the fact she had done it on sand. She bent her elbows slowly until her forehead touched the ground then pushed off, springing off the sand and twisting in mid air to land of her feet.

"If I try that I might die." You say after a moment of awe.

"It is simple muscle and flexibility, both of which will serve you well." She brushed her hands of loose sand walked to your side. "Back first and slowly." She said putting a hand on your lower back.

Not sure this is a good idea you slowly roll your back. You get a quarter back before her hand stops you from going too far. You look at her and catch her looking at your stomach before she lowers her hand a little letting you lean further back.

When you hit the point you feel you can't go further you are barely more than a third of what she could do. She holds you there for long enough that your stomach starts to feel tight. She seems to notice as well and pushes you to stand back up. She walks back in front of you and goes back to her exercises, most of which involve bending over to some degree and making it hard for you not stare but remembering her words from yesterday you manage it.

At the end she looks over her shoulder and holds your eyes. "Your control has improved." She walked over to her weapons and strapped them back to her waist.

"I'm as surprised as you." You say with a flirty tone. She eyes you as she finishes with her buckle.

"Most of the other students won't be up for anything more than basic forms this afternoon." She looked up and down your body. "I may be willing to offer you an additional lesson after class. You should keep your flexibility training regular."

"Then I will probably see you after class." As you say the words her eye flicks up to meet yours and you see a slight smile at her lip. "I'd never pass up a chance for you to teach me." Her smile stays for a moment longer and you wonder if her rule about not having relationships with students might have borne a fruit she hasn't expected.

"I look forward to teaching more than just flexibility." She rolled her shoulders pushing out her chest, the exaggerated movement and the shift in the conversations tone overcame your control and you looked down from her face. "After you last eleven minutes."

"Eleven? It was ten yesterday."

"And it was ten until you stared at my chest." She said with a quickly smothered grin. She was clearly enjoy this more than you though she would.

"Then I will last eleven." You say with a shrug.

"Good." She said it as she started walking away. "I will see you at class."

"Whatever you say Lady Stephanie." You make a faint bow and she chews her lip a moment before walking past you and out of the training arena. As she went she swayed her hips and you couldn't resist a quick glance. When you eyes returned you saw her looking over her shoulder at you but no comment was made.

When she was gone you smiled at yourself before being surprised at how calm she was about you breaking her no magic rule. That thought led you back to the fire ball and your need to be active, it was a little surprising how effective the exercise had been a cooling your blood.

You take in a deep breath to check you were calm once more and satisfied made your way back to the Dorms and the baths, wondering if the cleaning cabinets also covered singed clothes. As you went you look over at where you had tested your fire ball and saw the plants in a circle were slightly wilted. Could be worse all things considered, rather than how big you could have wondered how hot.
