Practical Jokes

... accepted my defeat and took the stuff she had brought. As I got back in the shrubs to get myself decent, my mind was already busy planning my revenge. Sure it was a deserved payback after all the humiliation she had gone through when her classmates discovered the kinky underwear, but I knew vengeance would be mine. After I had cleaned myself and put on the fresh clothes, I got back to the car. Even though I was still feeling a little miserable and looked like some gay fashion idiot in those leggings, there were no hard feelings.

What I needed would have to be the practical joke to end all jokes, and leave me forever as victor. “Get in the car, I’ll drive you to school otherwise we’ll both be late” I said as I tossed her bike in the back and got behind the wheel.
