In the dimly lit classroom of Panty School, young Japanese girls giggle nervously as their teacher, a stern, middle-aged man, begins his unconventional lesson. He demands they remove their uniforms, leaving them in only their white panties. One by one, he pulls them aside, his hands roaming their young bodies, feeling their budding curves. He slips his fingers into their panties, rubbing their tender slits, making them gasp. The girls watch, wide-eyed, as their classmates' panties are filled with his thick cum, their bodies trembling with a mix of fear and excitement.
