A dead-end job just became a gateway to hell... and the best sex of your life.
Your life is a grind. A brutal boss, a thankless job, and a future that looks as deep as the trenches you dig. But that all changes when you unearth an ancient, magical box. A single drop of blood is all it takes to break the seal and unleash Calysindra, a succubus imprisoned for centuries.
She offers you a simple, dangerous bargain: a lifetime of supernatural pleasure in exchange for your very essence. This is your story. Resist her seduction and seek a way to break her hold, or embrace the corruption and discover a power of your own. The choice is yours, and every decision leads to intense, explicit encounters.
