At the Mages school, Mai was busy practicing with her school mates casting spells.
"He ha, try aiming with both eyes Freed," taunted Mai as she dodged another stun spell her partner had cast.
"Gah! I'll get you eventually Mai," yelled the 14 year old bespectacled boy, red hair matter from sweat.
"If you can hit me, you'll pass the target test with no trouble," Mai said trying to encourage him.
"I can do this! I cah, cah, caACHOO," sneezed Freed as he sent off another spell from his altered hand motions hitting Mai full on, sending her tumbling to the pillows on the floor below. "I did it! I got you Mai. Are you ok?"
Getting up from her back where she fell brimming with joy at her friend, Mai pointed at Freed, "lucky shot, let's try aga- in?" Her voice turning to suprise as she looked at her hand closer. No she wasn't seeing things, her hand was growing. Looking at her other hand, Mai saw it too was starting to grow followed by her arms as it traveled up towards her in pulses. "FREED WHAT DID YOU DO?" Yelled Mai in understandable shock.
"Nothing, the spell must have changed when I sneezed," replied Freed, getting scared by this development as his only friend in the school was growing and it was his fault.
Mai watched as her hands swelled bigger, then her arms and then her torso surged wider and taller with each pulse. Her small mages robe getting smaller and tighter as her former 6" body expanded. It wasn't long before the robe gave way to her growth as did all her other clothes leaving her stark naked. They witnessed that Mai wasn't just growing larger, but was looking more mature as curves began to develop as her hips and posterior pushed outward, as did her breasts. Looking over her shoulder, Mai saw her wings were also growing with her, becoming more opaque as opposed to the near transparent look they usually had. Pulse, Mai grew to 1 foot high. Pulse, pulse, Mai gained 3 inches more from each of the rapid growth pulses, her breathing becoming rapid. Pulse, pulse, pulse, 9 more inches, pulse pulse pulse, "Oh gods this is incredible," breathed Mai as she grew another 9 inches, giving her 3 feet of height now. The pulses were increasing in frequency almost no pause in between the growth. Nai could feel her genitalia clench as she orgasmed from the feeling. The growth slowed as Mai approached 5 foot 6 and finally stopped at 5 foot 9. When the growth finished, sitting before Freed was a 16 year old much larger version of Mai.
"Freed, I need to borrow some clothes," Mai blushed covering up. "We need to talk to the professors.
