I get excited... by numbers, formulas, and my teacher's dick... My student, an intelligent science student, has a secret identity as a perverted handjob artist who loves middle-aged dicks. His dick is exposed in a situation where he can't make a sound, and he is jerked off with a smirk on his face, forcing him to ejaculate in shame over and over again! Jerk off until your semen dries out! Jerk off! Jerk off! He whispers to you, teases you, and stops just before you cum, leading you to ejaculate all at once! Your teacher's dick is such a wonderful dick that it's so much fun to jerk off...
