The plateaus should have "bosses." A super hot (choose gender) mega animal you have to "conquer" by sexing to unlock that subset. Vs just running up and humping. It will give credence to the stats, but the stats should be ejaculate (how much AND far it shoots), endurance, and etc. Each boss should require certain stats, toys, and sex positions to conquer.
We also get a short sex scene or when we hump; it goes into another world like old turn based games. I can't tell you how many times a furry just stood over me with his cock in my face. No, thank you. So when you hump a girl it's, its own dominion. You can't see most of the slime-girls dominations, because of the water.
