I imagine that the proposed create tag orientation play +66 tag, in conjunction with some existing tags, could cover most of the variants that lord411 listed.

Anyway, about those tag, whoever want to make, they can create it later by themselves. About the situation yaoi couple cucked by girl I believe only this doujin is the only one #178905 | Kyouei Mizugi Attack! | 3,223

Well I mean... This website also have a lot of NTR tag relate too... netorare, netorase, netori,... And also there's a tag call reverse netorare

Idk what to call it but i am more worried about how many tags will be needed if we note each individuals sexual orientation and gender. If we decide to do this i guess at least six tags will be needed to cover all types 1 yuri couple cucked by yuri 2 yuri couple cucked by guy 3 yaoi couple cucked by yaoi 4 yaoi couple cucked by girl 5 straight couple cucked by yuri 6 straight couple cucked by yaoi Personally I dont like these hyper specific tags

I see, then what should new name tag for this? How about "fallen yuri" or "ruined yuri"? I can't think better name, pls feel free to tell me

I don't think this tag is very important, but i have a correction to note. it's the "netoru" part that actually means cuckolding and the "-rare" suffix in japanese is similar to "-ing" suffix in english, it doesn't mean anything. "yuri-ntr" might be a proper name for this but that would be confusing as well; does it refer to a les stealing a guy's gf, or is it a guy stealing a les

cool idea, but if you're trying to combine yuri and netorare in the naming, then the description with men "stealing" would be incorrect; a woman can netorare a partner in a lesbian couple

Example: #642015 | Cool-kei Dansou Onna ni Kanojo Netorare… | 13,508

Example: #478758 | Kairaku no Shihai ~Watashi ga Chin Make… | 46,409
