Hijastro masturbándose en humillación de clase

Yep, I know... how bizarre, Yu's stepmom is also a teacher. Im subbing for your class today, so oops I let the truth out. You are a kinky filthy dirty stepson who is now going to jerk off in class. All the cute girls in class can see you. We all laugh at you. Even the girl you have a crush on! Ha! As You jerk off for all to see, I carry on with your classmates about how lame you are. We all have a good laugh while you look ashamed, red, embarrassed.
