Content notice: This game contains mature themes, including sexual content. All the characters in the game are 18 years old or older, both physically and in terms of age. This is clearly and unambiguously stated for all characters who appear close to 18. All "corruptible" characters are androids without consciousness in the game’s storyline (AIs in the narrative). All other characters — humans, aliens, or androids with consciousness — are not trainable. This distinction is clearly established in-game. Our goal is to create a respectable trainer game. The game features sexual scenes, erotic scenes and as sexual language, dirty talk, voyeurism, kissing, and characters depicted in underwear, full nudity, or erotic poses. The game includes various acts, such as: intercourse, masturbation, oral sex, handjobs, BDSM, bondage, anal sex, the use of sex toys, striptease, humiliation, rough sex, gang bang, bukkake, orgies, sexual roleplay, cunnilingus, cum shots, double penetration, spanking, nipple stimulation, and orgasm.

OPT3 Development Diary #1 - We’re Deep in Production!
Hello dear players! 🙂~ I hope you’re all doing well! I haven’t really posted much news on Steam since the release of Porn&Cards, and I was waiting to have a bit more content to share with you... so here we go!Right now, we’re deep into the development of Once a Porn a Time 3, and a LOT is currently in production. We’re slowly moving forward with the main story and side quests, working hard on new animations, and above all... we have tons of new characters to create! ❤️❤️❤️The game is heavily based on a classic Trainer formula where you get to corrupt princesses, and honestly, I love writing that kind of content ^^ It’s always a pleasure to watch a princess slowly become more and more perverted... especially since we’ve implemented a brand new skill point system: Magic / Corruption / Persuasion, which lets you train your princesses the way you prefer. And that’s pretty cool ~ Currently, our main Princess is Aurora, Sleeping Beauty, and then, throughout the game, you meet other princesses to corrupt (if you manage to ~) and plenty of other new characters! But I think it would be too much of a spoiler to say who ~ On top of that, we also have a whole other part of the game focused more on side quests and characters, which lets us develop additional stories and romances, just like in OPT1 and OPT2 ~As for the story itself, the main outlines are already written in advance, so the good news is: I know exactly where I’m going ^^ The beginning, the main characters, their development, and the ending are already set. I think when you play the game, you’ll realize how many things were actually planned since the very beginning of OPT1... eheh 😄And of course, even if you decide to play OPT3 only, you’ll still understand the story perfectly fine ~ A large part of the foundation we’re working on was made thanks to Porn&Cards, so we’ve been able to save time there. But clearly, what takes the most time is the story, the characters, and above all... the in-game animations.For now, w...Read full article on Community Announcements (Salty01)AnnouncementsOfficial
Once a Porn a Time 3 - First Look
Hello everyone! Ladies and gentlemen, the time has finally come to reveal Once a Porn a Time 3! There are a lot of big announcements in this newsletter, get ready! 😄 With OPT3, my goal is simple: create the BEST TRAINER EVER MADE. Yes — I dare to say it.So, this will be my final game, the one we’ll keep expanding for years and years to come. No new projects — all our work now goes into this one. No Steam release date is planned for now. 🩷 What can you expect from this OPT3? You and Tinker have to get the park ready for its grand opening in just a few days… But one princess still isn’t corrupted. The most princess of all fairy tale princesses:🌹The Sleeping Beauty – Aurora.And that’s all I’ll say about the story for now! 😏 There are plenty of new features — starting with the NEW SKILL SYSTEM🩵Persuasion / 💛Magic / 🩷Corruption Each time you level up, you’ll be able to choose which skill to upgrade! Each one changes how you train your princesses, unlocking new choices, new dialogues, and unique animations. You can even combine them for special results! Second important point: ROMANCES 💗💗💗This time, it’s serious — your choices will really matter. I was pretty nice in the first two OPTs, but that’s over! Eheh.Characters now have an affection system based on your answers. Some romantic paths can be unlocked — or completely blocked — depending on what you say. And yes, if you mess up, they can absolutely end up hating you. So watch your words ❣️Some characters will be fully romanceable — deeply romanceable — while others absolutely won’t. And of course, I’m planning multiple endings for the main story depending on your choices. Hope you’re ready!! 💘 To prepare for this new OPT, I replayed several classic Trainers — and one thing stood out: the best ones stay simple. That’s exactly what I want here. Back to basics, but with a massive technical and visual upgrade.We’ll start small, like in the old days: You, Tinker, and the Princess. (And of course, I’ll add all the twisted, p...Read full article on Community Announcements (Salty01)
