It depends on the shemale.
There are some that you can definitely tell have transitioned/transitioning. That is not my thing.
But the more feminine shemales, that is the danger zone!
I do not understand the internal conflict of the MC. Once you have crossed the rubicon with one daughter, surely the levies are broken and it's open season on the red foxes?
I can only echo the others sentiment. They just draw resources away from the main game update. Look at Power Vaccum and all the wasted time on the NTR side stories.
