Lilia has descended into the human world to become a full-fledged succubus! To become a certified succubus, you must complete all quests within the time limit! The main objective of this game is to progress through the main quest, milk NPCs for semen, and escape without getting caught by the police! Be careful—if you get caught by the police, you’ll lose all the items and semen you’ve collected in that stage!! You can use the semen you collect to complete quests or purchase items that help you progress through the game, as well as a variety of costumes!

Most NPCs have an “arousal level,” so they’re easy to seduce. While you can jump straight into sex, the key to success is “using items” and “satisfying their fetishes” to increase the amount of semen you can collect at once! Talk to your target, lure them to a quiet spot away from the police, and milk them for semen! Since each NPC has different fetish preferences, if you approach them dressed to satisfy their specific requests, you’ll earn a bonus of extra semen during the milking session!
