ema20's really something. The amount of fetishism and joyful sex - I mean this really lives up to the Lots of sex
tag - squeezed into 40-some pages is pretty impressive. Some of the dialogue is great as well, pretty rare to see Remilia wanting to fool around with her maids, or anyone in H-manga being so enthusiastic about getting to top. Also, "Hentaidou," lol.
tl;dr, good stuff.
