Futanari Female Knight Serena ~Cursed Milking Labyrinth~ I Had a Huge Cock Put on Me the Moment I Entered and Had My Semen Squeezed Out Again and Again

The female knight Serena sets out into the labyrinth where the succubus witch Vivian lurks, in order to break the curse placed upon the young lord Elliot.
However, she herself falls victim to the witch’s curse.
She grows a penis and becomes consumed by sexual desire—the “hermaphrodite curse.”
This curse will become permanent after one year, and she will never be able to return to her original form.
Can she overcome the monsters and dangerous traps in the labyrinth, defeat the witch, and break the curse?
