[tsuniverse (Yuniba)] Mage Teacher Possession Manga (Fantia) [desudesu]

A covetous old mage named Geppal triggers a mysterious artifact that pours his soul into his gorgeous colleague's body, sealing the busty teacher's spirit inside the trinket while her young apprentice scrambles for a way to undo it. Drunk on the weight of his stolen form, the possessor smothers the boy against her enormous soft breasts, grinds her bare foot against his cock, and strips away his resistance until he can no longer hear his real sensei's voice. With the annoying mage gone and a loyal young minion at her command, she celebrates her second life fingering herself to climax after climax, cooing about how much she loves being a girl.
