Setting aside the outdated graphics and translations that don't resemble any real language, there's hardly any proper adult content in the game. You play for a long time and all you get are some rubbing or kissing scenes. There's a corrupt-style progression for the FMC (female main character), where over time, the characters around you start eyeing you, and you decide whether you'll become corrupted by the events. As for adult content, beyond kissing or simple stuff, there's not much else. My advice? Unless you have a specific high interest in FMC games, don't waste your time. (Edit: In the latest update, an anal scene has been added and developer keeps updating it for now, check the genres mentioned in the "Genre" section to see if they meet your expectations and the date of my comment.)
