I spent the entire afternoon meditating in a secluded glade to perfect the pronunciation of a new grimoire. The mana flow was... stubborn. Frustration was mounting until a young adventurer stumbled upon my camp. He offered to help prepare my evening meal, but I had a different use for his youthful energy. I ordered him to strip and kneel, watching his eyes widen as I traced a rune of paralysis on his chest to ensure he remained still. I straddled his face, grinding my wet cunt against his mouth while I recited the incantations. The vibration of his muffled moans against my clit helped settle the magical resonance perfectly. I didn't let him touch his cock, of course. He was merely a tool to ground my excess mana. When I finally came, soaking his face, the spell locked into place effortlessly. He left dizzy and unsatisfied, while I successfully mastered a spell that can turn bone to glass. A productive exchange, wouldn't you agree?
