Anime teacher masturbates to orgasm in ecchi

An anime teacher locks her office door to masturbate in private after a long day. She rubs her large breasts with one hand while reaching down to stroke her pussy. Her eyes flutter shut as she builds toward a powerful orgasm, her hips bucking against the chair. The ecchi style highlights her pleasure with exaggerated expressions and detailed shading. Her hands clench into fists as she cums hard on her fingers.
