"MC" sort of get's himself into this situation willingly - but yes, it would be more NTR than NTS, I guess. But I really dislike actual NTS, where MC simply likes seing FMC doing it with others (usually as many "others" as possible).
If he consented to losing them both to the bull you could debate if its nts but id still pop it in ntr just me personally. By definition it would be nts though. Would end up nts with sex denial which i hate cause i dislike humiliation myself. How its presented, if he offered them up vs if they just got stolen flat out would be the factor. We both make valid points haha
