I'm going to be honest I'm not the biggest fan of the Pokemon trainer being made to be a terrible person. From I saved the world to Mrs.steal your girl
You know, an epic level troll would start going after Gloria's confidence. Playing up about how she's gonna be beaten soon. About how she's gonna get fucked like she's been doing to everyone else. How there's not a damn thing she's gonna be able to do as someone waltzes in, and summarily dismantles her entire Pokemon team, showing how she cares more about getting some pussy than actually being a good champion.
Cucking the futa who's cucking others, in a way, a la Rising Of The Shield Hero style one-upping.
But then again, this is NTR. And NTR is all about getting off on people not being able to put up a fight. In other words, unsatisfying Easy Mode Power Fantasy shit.
