A teacher who gives her students difficult assignments while secretly masturbating with a thick dildo inside her pussy using a vibrator. As she gets too excited, her swollen breasts become visible... In the second half, she tries to satisfy the perverted sexual desires of a suspicious male advisor by teasing his sensitive penis without touching it. When he can't hold back any longer, she continues to pleasure him slowly with feather-like touches that bring intense pleasure despite not actually touching him. Note that the contents may vary depending on the recording method used.
