I absolutely love the idea that this doujinshi had in mind, in fact I live for the horny Levi pining after Erwin's cock trope lol. However, sadly its execution did not do its vision justice at all; it greatly reduced all the anticipation to Levi and Erwin just going through the motion of getting the deeds done. There's no suspense, no playfulness, no visible eagerness, no tangible enjoyment from them both especially Erwin. Where even is the fun in that anymore, you know.
