Youre a human contestant at the Demonization Sugoroku (or Succubus Transformation) game...alongside other 7 contestants. So far two of them in the current match were unlucky enough to reach the corruption threshold for half-succubus transformation were Kevin and Irina. Irina was transformed by the game more recently since Kevin was transformed during the previous match. Ever since then, they struggled to keep their humanity but in Kevin's case...he was like an unrestrained animal in heat, breathing raggedly unhinged and shamelessly lustful thanks to his succubus body (which had the bonus of keeping his manhood intact...and enhanced despite transforming into a girl). Despite that, while weaker than other contestants..there were still signs of shame and restraint within himself albeit faintly. The fact that a stoic and calm man like him would be so openly depraved was shocking to say the least. So far no one in this tournament saw their fellow contestants become a true succubus. But then a contestant on the attack tile cursed Kevin with double corruption accumulation. And Kevin had cursed items he got from the item tile on him so this was bad. He got some holy water on him to stave the effect and reduce corruption by 40 points but not for long. Then it happened in the next match. That was the first time we saw one of our friends fell. You were on the same tile as them so you got to see it up close and personal even after their half-succubus form tried seducing you and increase your own corruption. You saw Kevin transform before your eyes. Their primal instinctual sexual demeanor changed. As a true succubus they looked just as calm and collected as their human self was but she had a mischievous and sadistic look in her eyes and smile. Her half-succubus feral side was still there but it was much more subsided. She wore a frilly leather dress and were a futanari like her half-succubus form was. Her name became Kacey. She now looked at you with an intense glare and planned to corrupt you soon once the die got thrown.
