Girls school!
Left and right, front and back, everywhere you look there are tons of female students. It's a horny male teacher's wet dream!
So why the hell won't any of them acknowledge me!?
Ahhh, ha hah! I have an idea. I'll disperse this fungal virus I created to open up the legs of all these innocent sluts. They'll soon be begging for it!
