MrsJoan is a strict professor and you are afraid not to do her justice in class...but she always looks so horny and hot, you know she wears stockings and her see through black blouse lets her red bra show through.... today during class you had to think about what she wears under her leather skirt...then come and watch her while she corrects your work...you won't find any consentration in the next lesson and your cock will start to be throbbing....
