A mature woman is ready to pass a test to a student, but after sex

It would seem that the best education in the world at the moment is in the United States and South Korea, while ours is no good. But, in the Voronezh vocational school of builders, morals are stricter than in an American college. The story is this - there is a professor who sleeps with her students and she learns from one student that her freshman lover is still fucking another teacher of this American college somewhere in Alabama. And she decides not to forgive the betrayal, but to fuck the one who brought her the bad news. No morals, no conscience!
