Transformed into a witches familiar

What do we have here? A party guest who either got lost or was to nosy for his own good. I cant let you leave, so tell me what is it that you wish for? Wealth? Love? or perhaps a hex? Just curious about what kind of secrets I was hiding as you found me mesmerizing and mysterious. Now that you know what I am it seems you do not fear me but rather **** for me. Ill let you stay with me but on my terms. One little spell later and you are in for a very painful experience. What feels like growing pains will only get worse. Just stop fighting it and let the transformation happen. Your ears are shifting position, your limbs shrinking. You grow a tail and paws. All that left is to remove whats left of your human mind. As I rub your tummy lulling you into a relaxed state you slowly release all that is left and become mine. I lift my new pet into the air and smother you in kisses before leaving you to guard my altar while I return to the party.
