I've said in the past. NTS.i don't mind waiting more lol let me again to be sure,everything happen only if he both agree? NTS is different of NTR,NTR choice doesn t matter
The whole story is how MC wants to share his girl. And Suzie will only do what the MC wants (mind you, this might not be what you want). So when it comes to the soft stuff, there won't be a choice because that's the driving force of the story. But there will always be an option for you to prevent a sharing sex scene if you don't want it. I don't foresee a circumstance where I would ignore that rule.
Example:
Anon tells Suzie to kiss a guy in the story (no choice here because it's the story), maybe they start getting into it more, and then you'd have a choice to:
A) push her further, make her do more,
B) stop it right there
Then in other scenarios her kissing someone else is up to you to decide when it's not a core story event.
Suzie's a little devil in her shell. She'll do nearly anything for her man if she's horny enough.
TL;DR:
Whatever sexual happens with Suzie, will be the MC's will and intent.
(Unless I deem it necessary for someone to, oh I don't know... maybe slap Suzie's ass... Just so I can give you the choice to make the MC to defend her honor or not.)
P.S.
I've said before:
I might do hard NTR (after the game is done), IF enough supporters on patreon want me to go back and make a NTR route.
