Murat, the 23 year old medical student

Murat was 23, a medical student, chronically undermined and permanently broke! That all changed when he saw the following job offer for a student assistant on the university's notice board!

Wanted: Stud./Wiss. Student assistant (20 hours / month)
I am looking for a student assistant who has the following characteristics:

Male, at least 18 years old, a penis of at least 14.5 cm in length (erect), gladly seen more;) Open-minded character

Contact Prof. Walter Schmidt if you are interested!

That was the opportunity! Murat quickly took a picture of the notice and went to the professor's office!
There he knocked! "Hello?" he heard a sullen old man's voice from inside.
"Hello, my name is Murat! I'm here because of your job posting for an assistant!" he said truthfully.
"Ah, oh yes! Wait a moment, someone will open the door for you!" came from inside.
Now Murat waited almost half a minute. During this time he thought he heard an electric hum and a short moan from inside.
Finally the door opened!
