Nathalia's step-sister has a perverted and annoying friend who always tries to flirt with her when he comes over. Nathalia is absolutely repulsed by him, and has no problem telling him as much. But today he uses a magic spell on Nathalia that makes her irresistibly horny and attracted to him - something completely out of character for her. Unfortunately the effects of the spell are short-lasting, meaning he has to use the spell on Nathalia over and over. This leads to Nathalia becoming very confused and angry at her own behavior. Topless, nude down to panties.
