If you ever want Asuna to have threesomes and foursomes then more girls need to be in the know. No guys are fine but girls yes
I think I have mentioned this on this very thread before, but I actually really don't like threesomes, foursomes or the like, even if they are 1 guy and several girls. This is not just in hentai, I don't even like the concept in real life.
I prefer focusing on a single girl all night, than diving my focus on several.
I know it's not the most common of preferences, since a lot of guys dream with having a threesome, but I don’t really get the appeal.
Also more girls knowing Asuna's slutty side won't mean less secrecy. It means more accomplices.
Here is the thing, I understand where you are coming from, but I like it when the heroines secretely betray the expectations of everyone close to them. Now, who is close to Asuna besides Kirito? Liz, her mom, everyone least favorite piglet (Inoda) and a bunch of nameless background characters that don't matter.
When every heroine is involved with Inoda, at the end of the day the only one who matters and won't know about Asuna slutty self will be Kirito.
And while I can see some positives there, with Kirito being the butt of the jokes to everyone while he remains an unaware cuck is very humiliating, I still would have prefer that things would not go down this path.
This is just what I personally would have enjoyed more, but Kyoko and Asuna being the cheating sows for Inoda while remaining unaware of the other true nature. And while I wouldn’t have added Liz to the harem myself, her being the only one who truly knows what goes on with Inoda and the heroines while being his masochist slave that helps him in the background.
