Teacher offers to tutor a boy

The mature teacher knew what he was doing when he offered to give private lessons. there were several boys whom he decided to take to his own house for lessons. but it was not about studying, rather they were life and sex lessons. all the boys were between 19 and 20 years old, were university students and had in common that they did not pass the subject no matter what they did. they only needed one thing to try, and that was to put the ass on this man. of course, all the boys with whom he fucked and had sex passed the subject with good marks.
