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
No but I didn't know I enjoy NTR until I read the extra (and I'm reading it again for the 5th time)
