But first he has to go through security.

"Stop right there, young man!" said a stern 30 something woman sporting a black witch hat and wielding a wand, standing at what looked like a check point just inside the building.

"Sorry, I'm late and I need to get to class." he tried to explain.

"Nevertheless you can't skip security," she replied, pointing at wall. It was covered in small boxes with glass doors with names written on them and inside....
Were a bunch of dicks. Well to be precise each box had a dick with a pair of balls in it, the view was unsettling but there was no trace of blood and a few that were turned backwards showed smooth skin where they should be attached to a body.

"What the hell?" mumbled K-T.

"Come on, pants down. Penises are considered contraband inside of the premises. While it can become a potent magical ingredient through alchemy, semen disrupts magical powers on contact if used the wrong way, so it's possession is forbidden in school." She explained and seeing as he was moving she twirled her wand, making his shorts fall on the ground.

As usual his dick was betraying him, starting to get hard from being stripped down. And before she could do anything else he was fully erect.

" Name?" she asked.

"K-T Smith" he mumbled, trying to hide his hard cock. With a move of her wand the boxes began to shift sliding sideways or up and down until she was facing an empty box with his name on it. She tapped her wand on his dick and it fel in her hand, leaving a smooth surface with a tiny pee hole on his crotch. The thought that he wouldn't risk of getting humiliated by being stripped didn't mitigate the fact that his cock would be on public display at all. His cock barely fit inside the small box as opposed the box on his left that contained some minuscule one inch cock smaller than the pair of tiny balls accompanying it.

"There, don't worry you'll get it back at the end of the day." said the witch with her back turned. And then turning around she added. "Don't forget to sign the ledger."

Only to see K-T turning around the corner of the hallway in a full run while trying to zip his shorts.
