A scenario is a reason plus a room
Every NSFW RP scenario that works has two parts: a reason two adults are in the same place, and a reason they hesitate once they are there. Rival thieves on one job, a bodyguard and the client, exes stuck on one case. Type whatever you have, even half a line, or press Surprise me for a fresh idea. The generator asks up to three questions that fill in the rest, such as the setting, how the two first met and what each of them is hiding.
From scenario to scene
Once the scenario feels right, choose the heat and the chapter length: short chapters suit quick back-and-forth, and long ones suit a slow evening. The scene is played in the full app on a free account. Take one character yourself in role-play mode, or let the AI write chapters while you steer. No Writer is the default here, so the tone comes from your turns, but you can pick Spicy, Pyra or Onyx before the first word.
