Big Booty Bookworm (Patreon)

While exploring a large, well stocked library, you find two things: an actual, authentic spell book and an curvaceous bookworm beauty with a big booty as you observe her from behind, you secretly test out a spell that EXPANDS her behind. She seems to be none the wiser as you follow her around the library. However, not only are you shocked that magic is actually real, but you're also quite surprised to see that the big booty bookworm noticed what you were up to, and even seems to be okay with it! She gives you one last BIG surprise as she reveals that she's found a spell book or two in the library herself, as she magically inflates her breasts to match the butt that you bestowed upon her.
