Dark Circus - college town stop

Kind of a pervy non-con dark/horror theme:

A Bradbury-esque dark circus arrives in little college town after little college town, each time bringing all manner of lechery and often leaving with a few girls who've unwisely let themselves be lured to "come along" with the train as it leaves..

(Just, if you write this, let's have some tickle-torture sex-fiends (clowns?) in the mix and a cute little college gymnast coed or two to fall into their clutches. )

Of course the mystic circus folk don't always prevail. Some towns are guarded by their own dark or light mages, or circles of angels or demons. Since the circus biz is not real hot in USA anymore, let's set it in an American past, or in rural Mexico or China or Angola.
