I don't think is a good idea not including the tag 'Netorare' when the cheater is a female MC.
There is not many tags related. Lovers use to search for NETORARE and NTRphobics (aka haters) exclude it.
No tags for cuckold, sharing, hotwife and cheating includes MC cheated, cheater or a NPC cheating other NPC then all this must included in the tag netorare tag.
Also only NTR, not netorase nor netori and idk if there are others (U have no idea how much I would like to bully everyone of you fucking virgins nerdy geeks when I read this words.

).
I mean, Netorare is the closest tag to what the potential player should be looking for and the only tag not throwing u 2000 games where only 1/50 is what u was trying to find.
