To be fair you could likely include quite a few new ones, in keeping with the setting, attatudes or edicts. Off of the top of my head there's Nurse, Teacher or perhaps Swim instuctor. You could also have some sort of "Dom" punishment session as well, in level 3-4.
Teacher and nurse seems the most fitting ones imo
Swimming instructor could fit too but it seems kinda pointless when the gym one exists as a "physical" job and I'd rather rework the gym one
Like fr it could have been done differently and much better.
The dom punishment is good as an idea but i feel like it would fit only on a sadistic karryn run.
Teacher and nurse would fit both playstyles and they could have good gameplay reasons too.
Teacher could have as a reward some kind of stat boost if you do it properly or a sexual tecnique boost if you do it in a "not so proper" way
Nurse instead could have a boost in dmg done to inmates as a reward(because karryn is treating their injuries so she will know their weakspots) and an increase in sexual dmg done if you did the job in the smut way
Both of the jobs could have lines for a sadistic karryn( sadist nurse/strict teacher trope) and both of them could have secondary scenes like the other jobs so for example supplementary lessons for the teacher one or a more "intensive" treatment for the nurse one
