Inside this labyrinth, magic operates under a special law: the stronger your futanari member, the more powerful your magic; and the larger your breasts, the more spells you can unleash. Magical power dwells within sexual functions. In other words, filling the Essence Cup with magic means... continuously offering futanari fluids to the cup.
