I remember I had this movie on video tape when I was younger (and video tape still were a thing ^^). I loved that particular scene. Got me every time !
Absolutely love this clip!! The look on her face makes it appear that she doesn't really want to touch him but she feels she has to. She is repulsed by the thought of stroking him and in her head she is thinking "Ugh!! You filthy pig", but she reluctantly does it because maybe she will flunk out or he may even hurt her physically if she doesn't please him! But still in the end she cares enough about him to gently wipe the cum from his cock... as if even though she didn't want to touch him sexually, she still somehow likes him as a teacher and wants to care for him! Very interesting and sexy dynamic to imagine here!!
