I was caught trying to sneak to the toilet in school, even though I was on diaper punishment. I was given detention and Step-Daddy was called to come in to get me. When I gave up on writing lines and decided to pout at my desk instead, Step-Daddy decides I need a little reminder to behave. He bends me over the back of the chair and lifts my skirt to reveal the diaper under my stockings. Then he uses the tawse to give me a good spanking before sending me back to finish my lines. Step-Daddy promised me a real spanking at home, but that tawse already hurt a lot!
