[tsuniverse (Yuniba)] College Girl Taken Over by an Old Man 1+2 (Fantia) [desudesu]

Bookish college girl Naho Koyama spends her days at a used bookstore under the admiring eye of her glasses-wearing manager, until an old man's black magic seals itself inside her curvy young body and claims it as the perfect new vessel. Trapped in a form he refuses to surrender, the possessor learns the spell demands regular life-force replenishment through sex, and the smitten manager is all too eager to keep her soft, busty frame charged. When Naho's cute friend wanders too close, one possessed body stops being enough, and a breathless threesome threatens to wring the poor man completely dry.
