Mature teacher looks at young lesbians from the side

Two young students come to a mature teacher home after class to pass the subject. The teacher makes concessions, but it turns out that the heifers did not prepare this time. The lady knows that the girls are lesbians and therefore asks them to have a same -sex sex in front of her and only after that the young lady can give them good grades. The heifers simply have no choice. Young lesbians rummage it properly on the couch, and the slut only looks at them from the side.
