If you think that was true ntr, I feel like I’m obligated to warn you before you delve deeper. Most Ntrs are about a third party r*ping a person in an established couple. This is like the cutest version you could have of ntr. It’s more voyeurism than ntr honestly. (There’s subcategories for ntr but I don’t know enough about it to figure out which one this would be and I don’t care to find out lol)
All I know about NTR was like when the third party likes a person and they get turned on seeing them getting railed by someone I've read those kinds of NTR that you described but I guess I just like voyeurism I guess
Yeah voyeurism with small NTR elements will be more your thing. If you go looking for regular and popular NTR, you’ll find a lot of dark r@pe stories with mind break and stuff like that(again there’s also like subcategories like netorase or whatever that mean different things. I don’t remember what they mean though but you can look it up to see if one of them fits your description better lol)
(Another fair warning is that a lot of NTR(in h3nt@i doujins) also often feature ugly bastards and stuff)
No but I didn't know I enjoy NTR until I read the extra (and I'm reading it again for the 5th time)
