Imagine this: We're roommates and I find you in my room with a guilty expression on your face and a pair of panties in your hand. I torment you about it, naturally. Coercing you to sniff and lick my used panties. Every time you do what I say I get so aroused that I grow (I casted a spell on myself that induces growth when I am turned on). I stop growing once I can touch my ceiling (I don't want to destroy the house today) This new height leaves me with no panties that fit and I decide to to put you to put you to good use and transform you, my panty sniffing bitch, into a pair of giant panties for me. Out of the kindness of my heart, I allow you to keep your sense of smell, taste, and touch. Then I put you on and tell you about all the juicy fun we will have together
