>>98337Not very far.
¥KoakumaSelf explanatory.
¥KogasaWould be embarrassed but enjoy being desired to such an extent.
¥SeijaWouldn't care outside of not wanting it solely because you do want it. Just don't ask or tell her what you're going to do and you'll be able to do it at least once.
¥SunnyDoesn't really get it, but allows it to happen so that she can get it.
¥DoremyIt's just a dream. Far from the worst she's dealt with.
¥YoshikaYou could probably get away with a lot more than just that.
¥KutakaWould consider you a weirdo but drop it pretty quickly as long as you didn't continue.
¥ClownpieceYou're getting violated.
¥ChiyariDon't disturb her too much.
¥WriggleMostly just happy to be seen as a girl.
¥AunnKnows you're being a pervert, but wants to help you deal with your urges.
¥KasenYou're not getting any sleep tonight, and not for any fun reasons.
¥LunaKnows that you're doing it because you're attracted to her, but doesn't properly understand it.
¥KoishiWould grope you back.
I think that's basically the best you can hope for. Anyone else would end poorly. You either wouldn't be able to do it at all or wouldn't survive doing it. Like Meiling, who'd reflexively kick your head off.
