yes, later I knew what you meant, indeed there are those scenarios but it has its pros and cons at least these two.
-In Quetzal's scenario you have that role but moderately active, she only gives you a bj.
-and in Urka's scenario in the camp it's more fucked up because in the scenario where you only give it to her, she doesn't let you finish, you end up fainting and that's how the encounter ends, on the other hand if you choose the scene where you switch between the two scenarios, it's more complicated, she just destroys you.
not to mention that Urka is too darn dominant and if you accept the slave option your active role is over.
I mean it's true what you say, but damn, man.
