A little boy comes up to you and says that he loves wolves and wants to be one. You hand him a costume that becomes a skimpy fur outfit and turns him into a busty blonde, and to make the girl even more like a wolf you make it so every spring she'll go into heat for about a month and need to have sex several times a week. But your nice and make her immune to STDs and that she can only get pregnant when both her and her partner want her too.
