Imouto Wa Mesu Orc (“My Little Sister Is An Orc”) volume 1 [English], by Muneshiro

Stepsister.

–Update: there’s a second volume, now!

In this share, we’re in a version of Japan in which demi-humans and non-human humanoids such as elves or orcs are nothing big, they’re part of society. The male MC’s sister remarried to a good-looking male orc, and now he’s got a brand new sister, by the looks of it of highschool age, looking like your normal hentai world hottie, save for the funny ears.
Just like any other hentai world imouto, she loves her new brother, and just like any other hentai world imouto, she’s in heat several days per month, suddenly stopping to be shy and reserved. Er, wait… that last part is only my wishful dreaming, that’s the current manga’s idiosyncrasy

I was SO relieved the “orc” part was nearly nothing at all, I tell you. What remains is rather good sex with a nice meaty girl, simply, enjoy! ^^
