Tell the girls your the substitute teacher
From Create Your Own Story
"Girls, I'm your new substitute teacher" you tell them putting a bit of power into your voice so they they will believe you. they all nod there head and take seats in a simi-cercal anround you. "Now," you say," you are all here because you are all slags. Now because of this I believe that you all need punishing"
What do you do?
Make them all allergic to clothes and super horny (ngm)
Fuck them all and make them pregnant with your baby instead.
