I dunno if he even appeals to NTR fetishist or to cuckolding fetishist. All I've seen are claims from NTR fetishist claiming its not even NTR since most of his stuff includes the player enjoying it. If I recall only his Arona defeat stuff come close to it.
Tobs stuff is the closest to NTR referring infamous Brienne/hobgobbo and Marefolk shaman scene. Funny how some modders and community writers prioritize what the main playerbase wants than the Dev and some main writers who prioritize their fetish more.
Pretty much my view is, Savin's "NTR" is annoying. Tobs "NTR" is infuriating. And if i recall my experience with NTR materials i think Tobs hits closer. Now he just need to stop messing up with our cow wife and do that to the pink punching bag and It'll be fine.
Savin is a Netorase enjoyer which is under the umbrella of NTR, it's where the protagonists enjoy watching their girl get fucked. He likes watching stronger more masculine men take his women. That's his fetish. It shouldn't surprise you that these guys are the most obnoxious of the fandom. They're pretty much why you keep seeing people push for NTR and why there's an equal and opposite reaction that's just as hostile. It's also why he completely hijacks your character's agency to express his love for being replaced.
Tobs thinks if you get close to anyone, feeling genuine affection for, that's bad so you should hurt people that feel love, but that's just rape. Netorare is that the love interest is enthralled by the other and consistently cheats on their boyfriend/girlfriend without their knowledge or to the devastation of the boyfriend/girlfriend. What Tobs wants is to destroy, not take. He's that adage that some men just want to watch the world burn.
Netori is where you steal Savin's significant other from him.
Why Japan has this many differentiations for cuckoldry I'll never know. I guess they're like Germany where Germans need a word for every feeling, the Japanese need a word for every kind of perversion. Anyways, I go into this spiel because knowing is half the battle.
Agreed that Cait should be designated punching bag.
