Amy smiled deviously as there was a loud snap in the air, and flashes of lights popped outside.
She had cast a simple emotion-control spell on the misbehaving boy, which would cause him to be intensified sexually aroused. Emotion control was laughably basic, and counteracting the spell required virtually no experience whatsoever. The boy-turned-girl would just feel increasingly horny, and once they realized it was due to an incantation, they could easily overcome the sensation.
The emotion spell hit the girl suddenly, and she gasped at the powerful experience, her shiny red lips making a perfect "O". The new chick's nipples hardened enough that they could be seen through the thin dress material, and she gasped while slamming her knees together, her high-heeled shoes splaying outward. Her manicured fingers grasped the bench she was sitting on, hard enough to turn her knuckles white.
Now, all Amy had to do was watch the girl. The girl was just sitting on the benches outside of the library seemingly just waiting for the dance to end. She didn't get up, or even attempt to counter act the spell.
How odd... He has to have noticed! What kind of pervert goes to all the trouble to blend in, just to hide outside?
No, no, no my good lad. Amy thought to herself. You made this change to yourself, you are certainly going to experience everything womanhood has to offer.
Amy used a quick magic spell to get the girl to stand up, and walk back towards the dance hall. Ahaha, lets see how you like it when you're back in the Jungle, girl. Amy chuckled.
