Young Joyce couldn't sleep until she found the answers on all her questions about the school subjects. The last topic on phisycs was really difficult and the girl had to call her teacher to ask him for extra classes, she didn't want to fail the exam. But from the very first class they payed more attention to pleasing the lust of each other then to studying. Joyce didn't feel any disgust to the old perverted man. He was really skillful and his cock made teen beauty scream and cum several times. She bursted in to tears after the last orgasm and physics now was her favorite subject.
