[Hikagemon] A story about a world where a girl suddenly becomes a succubus one day [Incomplete]

Miki's ordinary schoolgirl life shatters the day she awakens as a succubus, complete with a spaded tail and a body that aches for cock—and the only man around to help is a bald, heavyset old uncle her boyfriend despises. Forced into his hands right after school, her huge breasts bounce as she services his massive shaft, her face twisting between lust and hatred while she internally screams that she has a boyfriend. By the time he's pounding her drooling pussy full of creampie and telling her he'll see her next week, she's left comparing the two cocks and dreading that ordinary sex may never satisfy her again.
