Twelve little maids from school.

Just as you thought this seems to be a dormitory of some kind. There are, perhaps, a dozen forms whose size indicates they are in their late teens. Despite what the woman said many of them are still talking. The scent of them is intoxicating, both because they are filled with the blood you crave free from the impurities that older people fill their bodies with and because you can detect a note of sexual arousal coming from a couple, although in this form you cannot make out words, only sounds.

You wait until the noises of talking have died down and the sounds of sleeping are all that remains. You crawl into the room and change into human form. The twelve sleeping forms are a godsend (if that's the right word given your current condition) allowing you to take a lesser amount from each than were you to **** to feed on one alone, decreasing the weakness they will feel afterward and thereby the chance your midnight snacking will be recognized.

Twelve young women, all of whom you plan to sample before the night is through. But were to start?
