I mean, they do talk about it in the sub route and all, maybe there could be another conversation about it when it gets to very sub, about if the MC is okay with it, something can look like NTR while still bering NTS, it depends on the MC liking it after all. So if the MC likes the humiliation part, if its something that turns him on, like how Oliver treats him, then while on first look it may look like NTR it would still be NTS nonetheless.
Personally I imagine the MC having less sex with her, so I hope there wont be reclaim talk and pics after every time xD but generally, could maybe be a thing.
Pretty sure something like that is already floating in his mind, I would expect so at least, just seems like a natural step at some point, similar to watching live (and later talking about it, because phone game
)
