An hour ago, a woman suddenly appeared in my room, claiming to be a succubus, and casually started relaxing with an innocent demeanor. She introduced herself as Ena, a rising star rookie succubus from the Demon Lust World, sent to the human realm for the "Penis Point Competition"—the most important event for succubuses. In this annual contest, which determines their rankings, the succubus who collects and consumes the most semen from men with no romantic prospects earns the highest score. Ena chose me, stripped my body completely naked using a secret device, and forced me to drink a special aphrodisiac used in the Demon Lust World. As a result, I became completely obedient to her commands, climaxing repeatedly. Repeating phrases like "I don't just want your sperm—I want your heart melted," "I'll take everything you are, body and soul," and "I want you thinking only of Ena," she gradually took full control of my mind. Thanks to this, the film was completed as a commemorative work for KMP's 20th anniversary.
