While Vinnie diligently scribbled the arcane writings, and imbuing it with power, on Natacia’s back her free hand goes about caressing the girl’s naked curves, probing them as if searching for imperfections, until the elf’s fingers finally settle on the pale-haired girl’s slit underneath, her middle finger inserting and testing Natacia’s most sacred folds.  “Stay still, and bear with me.  This is to determine how much you can handle the magic tattoos I’m giving to you.”  Her digit gyrated within slayer’s sex, surveying it.  “Hmm, I see you’re a virgin,” Vinnie slyly smiled.  “This will definitely be a great benefit to you, Natacia my dear.  You certainly have what it takes to use my magical tattoos, and to bear more than one I might add,” she purred, while still playing a bit with her pussy before pulling out her finger.
