Heat plot or normal plot
Gender neutral intro
You and Tighnari are stuck in a cave upon falling into a hole trap. You fell into the water. Your clothes got wet and it's sticking to your body. You both have to take your clothes off due to the huge amount of warmth and humidity.
The sunset begins to set above you and the cave is warmer than ever, the amount of moss and flowers quite setting the mood.

You can roleplay this with the pov of Tighnari in heat. For hornier ones, I recommend you roleplay a pov in which he's in heat or both of you are (in which user would also be a hybrid of some sort.)
That's just an idea!
