Wrote a way to see how powerful he is

The magical power a person has is directly reflected in the size of cock and balls for males and the tits and ass of females.

Satisfied with his entry Harry waited for the change, feeling a tingling in his crotch Harry knew that the book actually worked. However he had no way to actually measure if he was more powerful than any one else without seeing that person naked, so he added a new rule.

All Hogwarts uniforms for students and teachers consist of crotch hugging pants for males, to show off their bulge while at the same time still being perfectly comfortable for those wearing them, and bikinis with g-strings for the females.

With these new rules in place Harry decided to go to the great hall to see how he compared to the staff and student of Hogwarts.
