For the anti-NTR purists it should definitely have the tag, imo. There are many dream/vision sequences that have NTR of your 'roommate'. The 'mom'/moms-friend gets attacked and bitten by a vamp, but i don't recall seeing any other scenes for her.I read in a post that the mom was raped by a vampire...Is it true? If so where is the NTR tag?
There are also others when your 'aunt'/mom's-friend's sister and her daughter get banged by ghosts.
The Doctor isn't an LI so far, so it could be argued that her scene isn't NTR. She does catch you watching and seems to enjoy it though, and who knows what will cum later.
