Adding onto what droglob said, it's one of the more unpleasant truths about game development. I would love to have Karryn be more dominant towards the enemies, and not just through the things she can do in the delayed Gym DLC or the Amazon position Sex Skill. I'm talking about stuff like anally fingering them (which can be another petting skill besides Pet Cock), spanking them (also another petting skill), and putting on a strap-on (either single or dual-headed) and pegging them in a variety of positions.
Unfortunately, it's probably too much work atm. It may not even be something Rem and Sachinama may be into to justify the effort working on it.
All of this will likely be relegated to fanworks/mods.
