From comment on the parent post: "Post Title on Pixiv: I couldn't decide whether to draw MeilingXSakuya or OrinXSatori, so..." with the parent post being futa Meiling with Satori and this is the opposite pairing.
From what I can tell, Meiling was kidnapped, Sakuya attempted a stealthy rescue but got caught, and now Satori is watching the above scene with Meiling whom she is currently holding hostage... (I'm not sure if the related post is supposed to be occurring with this)
