A shy goth girl with a "SWEET TOOTH" moves in with too much luggage, too many secrets, and a second personality that's been waiting a thousand years for a chance to take control.

A goth girl moves in. A virgin body. A thousand-year-old succubus sharing the same skin.

Phylia is shy, soft-spoken, hiding behind oversized sweaters and round glasses. She keeps her head down and never dates—because every time her body starts to want, something else wants more.

Her name is Calliope.

An ancient demon of pleasure, burned at the stake a thousand years ago, reincarnated inside Phylia's untouched . Arousal is the trigger. Every blush, every throb, every shameful slick of need—it cracks Phylia's control. And when she breaks, Calliope takes over, using Phylia's tight virgin body to hunt again.

You just became her roommate.

One Body. Two owners. Phylia thinks she's safe.

Calliope knows better.

Can u figure out how to stop calliope or let her have full control?
