The lessons were over and Sheyla was waiting for her friends at the street and reading the book. That moment her teacher was passing by. He noticed a sexy teen coed from his university standing alone in a short skirt and talked to her. When he found that Sheyla was reading math theory to the exam he offered her some help in it. In 10 minutes the coed was naked on his coach with an erected cock in her lustful mouth. She didn't think that old man can be so good in sex. He drilled Sheyla's cunt and finished on her round buttock. That was a hot math lesson.
