Here's some minor spoiler content: The more common definition (which is often a cuckold style) "Netorare" is unlikely to ever be included. Other definitions are possibly more likely. Technically my first game, Alive contained a version of NTR (I forget which definition, I always get them mixed up) where it's possible to steal your best friends girlfriend. Most people wouldn't consider that NTR, but since people *do* use different definitions for the same acronym, some people would - but not the "netorare" version. So if you mean "Netorare" - then it is a probably not. If you mean other versions, then it's a "possibly, I'm not saying yes, I'm not saying no, I'm just saying I won't spoil future content"
