The female teacher tells the girl she must be disciplined. She gives the girl a new uniform to wear. The girl must undress her old uniform and hand it to the teacher, including her panties, which are carefully examined by the teacher.

The new uniform is different in many ways:

Tight blouse with Navy Blue tie
Knee-High Navy Blue socks
Extremely Tight White Frilly Panties (with "Property of Teacher" inscribed on the crotch area)
A very short Navy Blue pleated skirt (not quite covering the girl's bum cheeks).

The girl nervously dresses in her new uniform.

The teacher then takes the girl out onto the school field, then has her stand with her hands above her head. The teacher strikes the girl's bum with her cane and orders her to stand with her legs apart.

The breeze makes the little skirt expose the girl's panties.

Teacher has another surprise. She inserts a vibrator into the girl's pussy. The tight panties hold the vibe inside the girl. The vibrator can give pain and pleasure.

The teacher smiles and shows her a handset remote control, then leaves her standing in the field.

Lunchbreak arrives, and many pupils cross the field, many of them gathering around the girl.
The boys cocks harden at the sight of the exposed and very fuckable girl, and the girls ogle as well, while using the word "slut" often.

She is not allowed to speak...

"What are you doing out here?" A female pupil asks...

"I'm...being..."

The teacher, watching from afar, heard from the microphone in the girl's blouse, and promptly punished the disobedient bitch by pressing a button on the handset...

The girl squeals and grabs her crotch in front of the crowd...
