there is NTR in this release - in the second part later this year there's a chance also to have NTR in at least one scene (maybe martin?), but that 2nd part is too far away for getting into details.
Even in this part there isn't really ntr based on the real definition, but we are aware how people see it over here - so just to avoid a later rage, i go with F95 definition, so yes, there will be ntr (no one is trying to steal anyone away, but still fucking behind the back). Going by that, there is at least 1 scene (indecent proposal). going by F/F (like recently happened in SL between Sis and Vicky), then there are 2 more "ntr" scenes. The only "vanilla" scenes (if you count (3+)-somes as vanilla) are "family reunited" and "three's a crowd ...".
"Sleeping with the enemy" is MC cheating on Dee.
Rocky scene doesn't need any further hints XD
The rest you will see at release.
NOTE:
There will be a disclaimer before starting every scene to explain the setup, the background and what to expect (so that certain kinks are obvious before starting the actual scene to avoid unwanted content)
So READ the disclaimer and play on own risk - and don't complain when you might see content you don't like
