Semantically yes.I should have specified ntr, but unfortunately as other users have pointed out, there is no good translation for it in english. Having one's cherished person, to which a certain amount of love is held, be stolen away from them sexually, while being unable to do anything is a form of ntr. It isnt the same as cucking and I apologize for the confusion, I am also not the most proficient with english and just assumed it meant the same as ntr.
It is more cringe for me that scenes are written about things that could be easily avoided. Give me some interaction, let me decide if my character watches and cries or intervenes in a show of dominance. I know Savin can write scenes like this, cause he did write for CoC 1 with helia, a scene where you can steal her away from a minotaur.
