Though trembling with nervousness during her first introduction, memories of high school bring a smile back to her face. The days spent passionately making out in uniform remain vivid in her heart, and she still cannot forget their warmth. Yet hidden within her is a forbidden secret—masturbating inside the school.

Her students become captivated by her thick, alluring breasts and wet pussy, gradually developing a deep interest in her. Amid this daily routine, an unknown desire begins to stir deep within Kirari's heart.
