While giving assignments to her students to help them overcome their weak subjects, the ass teacher indulges in a sticky piston-like masturbation session behind the desk, shoving a very thick dildo into her pussy. She is so turned on that she writhes in pleasure, exposing her voluptuous breasts... In the second half, in order to relieve the perverse sexual desires of a male instructor suspected of sexual harassment, she teases him by almost touching his sensitive penis, but not quite. When his pre-cum starts to overflow, she uses a feather-touch to maintain the pleasure, making him writhe in pleasure.
