Would say actually fairly the opposite. This Sidejob falls in the same Trap, the Gloryhole Sidejob fell. No meanigful Gameplay at all, while ignoring a Core Mechanik of the Game. Gloryhole and Gym Sidejob both are just you looking at pretty pictures. What you actually do doesn't really matter at all.To be fair, this DLC does what the other side jobs accomplished. A: A costume theme. B: B: sexual act with said costume. C: mini game with art pertaining to the setting.
The Waitress (going around giving the ordered drinks)/Receptionist (processing visitors)/Stripper (paying attention to the moves patreons want to see) Sidejobs have a clear Gameplay Loop of what you should do and it comes with dangers while doing it but they also come with a Reward doing them. Even for Slut Karryn they offer a Gameplay Loop.
Waitress you can expose your Tits for Money, can make out with Prisoners for money etc and try to get the Sex Scene at the end for extra pay.
Receptionist Side Job falls a little bit Short on the Slut Karryn for Gameplay Stuff but it at least sells a nice Fantasy even though I would have liked it, if Slut Karryn would have been fleshed out more there.
Slut Stripper falls off more, since Private Dance Show should have been continuation of the Normal Minigame with Lapdance stuff and so on but again at least you can make extra money at the end even if it is just a glorified Defeat Scene.
Now look at Gloryhole and Gym Sidejob. What is actually the Gameplay here? You are just picking whatever Sexskill you want to use. That is it. Even something basic as, Using Observe to read the eyes of a Prisoner to get a Dialog like "Awwww, he is looking at my Tits... well I know what he wants" so if you then give him a Boobjob it gives you some sort of a Bonus, would at least add some sort of Gameplay. But no just like with Gloryhole you do whatever until you are done and that's that. If I just want to look at pretty pictures, I don't need to play a Game.
