Imouto Wa Mesu Orc (“My Little Sister Is An Orc”) volumes 3, 4 and 5, + a full repack with the volumes 1-5 together [English], by Muneshiro
A stepsister: the best of both worlds, the sweet taste of taboo, without the slightly vile vibes of the actual deed
And so, here we are with a bit of catching up, after the volumes 1 and 2, here are the volumes 3-4-5 of Imouto Wa Mesu Orc, plus a repack with all 5 volumes lumped together
We’re in a wonderful version of the hentai world, in which humans and all sorts of demi-humans cohabit peacefully in today’s Japan. The main character is a young adult whose sister married an orc, and so begun his relationships with his new orc stepfamily, 2 stepsisters and a stepmom.
Female orcs enter a mating frenzy once a month, and the custom is to assign them a partner to “relieve” them during heat, this way no random scumbag will put his hands on the goods.
Of course, it’s our lucky male MC who is chosen for the job =)
All along those 5 volumes, we’re treated to tons of awesome fucking. Mostly stepsister #1 (meaty, glasses, oh god those boobs), but also stepsister #2 (meaty, hotpants, oh god those boobs), plus also the stepmother (meaty, awesome MILF, oh god those boobs) and a dark elf highschooler as a side dish (dark skin, gyaru.)
I resented the too numerous dark censorship bars, and the artist’s choice to focus on body parts rather than full body shots at times, but, eh, overall, that was fucking brilliant, I’d say
I hope you’ll enjoy the read! ^^

Just gonna put this here for anyone who needs it.

Thanks Oliver
But just a note: it’s sister-in-law in this case, not step-sister…
But of course, that doesn’t change the awesomeness of this series
It’s just a matter of time until the mother-in-law shows up.
Like in the 3rd volume?
Yeah I didn’t get it. She showed up.
Or maybe it’s a step/in law confusion?
Oops, flipped through that volume so fast didn’t even notice that was her, thought that was the sis-in-law again.
I owe you one.
After pestering you earlier about the later episodes, I completely overlooked this final complete installment. So thanks for that.
My final thoughts, though, are mixed:
While it was a solid hentai release, the – novelty? – of the first episode kinda wor off on me. BJD-kun never got any deeper – storywise, not in cm…
Sadly, the formula was “I’ll rule the metahumans with my enormous tower of endless power”, so all of them succumbed to the human überdick. 1.chapter, page 18 was kind of a giveaway, that “shove it from behind like a pig (Orcs are often depicted with pig-like faces in Japanese manga/hentai)” set the tone. There ARE nice/funny moments, yes, but in the actual act they all became meatpuppets, even the mother.
So – as you call it – fappable, but sadly no interesting story development.
As early as Ch2 I was thinking it would be cool if the MC had a very uncomfortable (for him) conversation with his orc brother-in-law about the situation…
