I think you used the wrong tag? I don't know, but thats Hubert, and you used the tag for Herbert (Project Moon), which is a different person... Theres a tag for Hubert (Project Moon) though, in case you did this on accident?
I was thinking this myself, but I'm not sure what the tag convention would be.
I've seen people drawing Kanbaru's outfit (e.g. post #11205979) I've got a few queued up I could post. Also Ononoki. I haven't seen many of the others yet though.
I tried to translate for the first time. I'm not exactly fluent in Japanese so I also compared the translations of @Modieglh and @Yukishiro_R on twitter (X) along with a machine translation. I'll be glad to take any advice.
There's a new phenomenon in the twitter artist community that, to show they're not AI, they just post the picture with the entire drawing tool's interface. Personally, I'd just crop it, but I'll upload as is.
Unable to ascertain who exact animated this, as it's based off of CG from りょうじょくっ! at DLsite. According to Paheal, the earliest instance of this animation can be found from /fap/ on swfchan.
The name of the source file from this upload sounds like unrelated spam.
