Big-titted female teacher Koharu plays aggressive pranks on her students one after another. After class, she calls students out and suddenly gives blowjobs, carefully licking their perineum in a bold manner. When a student begs her, "Fuck me!!", Miss Koharu responds passionately with full-body licking and face sitting, then mounts him cowgirl-style, thrusting so intensely that the penetration point becomes clearly visible. She satisfies each student thoroughly, creating what feels like a deeply healing experience.
