Ohhhh. Hm. Well it’s Not Really the Opposite, It’s More of Like, NTS is NTR But You Like It. Thanks CuckChair for the Information
You're welcome <3
No, NTR is straight up cheating, NTS is more like one-sided swinging. If the husband/bf is aware and has approved, it's not cheating and not NTR.However, many NTS stories do turn into NTR if the woman starts going behind her boyfriend's back
