I'm down for good NTR, and down for good vanilla or swinging where the MC gets something other than losing his women for (insert low effort plot device for "new guy has bigger pp than MC" trope). It comes across as a somewhat copypasta netrorase cuckold-ish story. Thats more the issue I have. No ill will to dev, but this one is unimaginative.
As some have said, this isn't swinging, as MC gets zero benefit out of it whatsoever, but I'm aware that "swinging" is being used as a placeholder tag for netorase for now, so it is what it is.
Humiliation tag might be a appropriate tag given the context that MC is made to give access to his women to a "superior orc" with the context giving the vibes of NTR even if he's not totally having them COMPLETELY taken away.
