Ok guys, I think I figured out how to get the Love Slave route aka moving the needle to the right during the Violation Route.
*Firstly, it is helpful if you get the Dom level in her profile to be fairly high or yellow.
Now, on the 1st, 2nd and 3rd stage =
(1) Make her cum once
(2) Insert penis
(3) Keep thrusting and be mindful to choose the Slow or Rough that the red arrow is pointing to
(4) Keep making her cum by continuing to thrust BUT do not cum yet
(5) When her Pleasure Meter no longer increase even if you choose the red arrow action, then that means you should CUM OUTSIDE.
-By the 3rd stage/event, the needle should already be in the Love Slave section.
-4th stage is just Blowjob in the bathtub and I don't think it matters what you choose.
-At this stage, she should already be your submissive bitch.
-BUT even so, DO NOT CUM INSIDE of her in 5th stage.
-GODDAMN that Vibrator sound in stage 6 is annoying!
(6) At the last Stage (Stage 6), if you make her cum repeatedly until it becomes the last RED BAR, she will faint and it will make the needle move to the left.
*Edit = I may or may not be right but I don't think cumming inside matters much but rather it it the "Strike" command. Maybe slapping her is the real factor. But I cummed outside just to be safe
*Edit no. 2 = I think I've narrowed down the factors. Following my guide and never cumming inside her + not hitting her during the foreplay will move the needle to the right. Follow my guide BUT cumming inside her + not hitting her will no move the needle. I think hitting her during foreplay moves the needle to the left.
I did a run where I picked every Affection option possible (with Q.Save/Q.Load help), then unlocked the (I guess) secret ending, then on the last day (in that last day instead of saying pure love or violation route, it shows "???") I made a save. Then I started the violation route, her levels where:
Affection: Loves
Alert: Low
Dom: Low
I followed your steps, but I focused more to always pick the "red arrow" option even before you insert, and always avoided the "blue arrow" option, and managed to get the needle all the way up to the right, by always picking the "cum outside" option (in the penetration stages, in the blowjob ones in doesn't matter.
About your Edit 1, it's actually the other way around "cum outside" it's all that matters if you want to get the needle all the way to the right, hitting her doesn't. When the needle is at least 1 step to the right, the needle won't move at all if you cum inside. The needle will only move to the left if the needle is in the middle and you "cum inside".
Btw, I'm still yet to get the other 2 ends you can get in the violation route. I only got the True Love one, the I guess "secret" one, and the Pet Slave one (the one you get by moving the needle all the way to the right in the "Love Slave" section, unless there's another one), and to be honest, for doing all this and being forced to always pick "cum outside", in my personal opinion, it's very lame. I hope the other 2 are better.
