First panel, is that the "maid of fail" pose from that comic where a maid Meiling is trying to raise Sakuya into being a good and ressourceful maid?

Yes and no. That's indeed the same pose, but the original is Kasen's, and it first appeared in the first chapter of Wild and Horned Hermit

Kasen: All according to keikaku.

Thanks for the translation, MCDecaux. I wish more of Niku's comics were translated, but I guess not every translator is willing to translate the lewder stuff on Danbooru.
