There is! You can (and it's not very difficult) fight agaist them and then make some of prisoner and they woman pay for crossing you path. But again - if you got careless they do what they want
Yeah I liked the fight mini-game, it's not very hard but just enough to make you feel you actually did something to earn the "reward"... but there are a few problems with that still..
First of all considering all the aphrodisiac premise you kinda can't be sure that nothing's happening with the girls when you just aren't there to protect them, and well you're in the damn prison full of dudes I mean. but even if we assume that every day just the girl you picked gets attacked and if you win the fight you're good then there's another problem..
Maybe I'm not good enough idk, but it looks like you
have to miss a few ambushes bcs you need to do other stuff throughout the day to actually get a good ending, and maybe Im wrong, but the prison guide kinda implies that if you missed one it happened..
All in all could use a little clarity on ntr and whatnot, that is actaully what a lot of games with avoidable ntr are suffering from. The most easy way to handle it imo, is to add some trackers for ntr stuff so you could actually see when you avoided it. Something like "fucked by prisoners", "fucked by mc" for the girls in the prison guide for example. And if you dodged everyting, add a little confirmation "You even managed to protect every one of your girls and escape with them untouched." or something like that in the ending screen.
But also I mean as long as the quest itself is avoidable and you can just not do it at all, it's probably not worth to bother..
