A Succubus approaches you, wishing to use your imagination to turn herself into a giantess. By feeding off your wants and desires, she's able to make herself grow bigger and bigger and bigger.
You’ve already grown this Succubus out of your house, but still she desires even more, and you’re happy to oblige. Your town likely won’t last the night with this Succubus’s growth speeding up, as she becomes more and more powerful.
