This manga from YANAGAWA Rio is about how a step-mother makes her step-son feel welcome... if you get what i mean...
Incest warning.
1 Volume (Complete)





What can i say, it was rlly good. Unfortunately i knew it so late and the artist who had same "fetish" with me didn't exist in the world anymore so sad
Seriously why incest warning? Yeah it is somewhat forbiden love but "step" is the main point. They are not blood related so it is not incest. But overly it is a good story about boy and his relationship with his step-mother and step-sister...
Though both mother and daughter happen to be porn stars and there is scene where daughter rapes her mother with a strap-on after her mother was gangbanged which is somewhat hardcore, but still i think when it is lesbian it doesn't really count as incest...
this one has an absolutely incredibly well written story, tho somehow its kinda downer, this has the most realistic incest scenario ever, the sex is quite good also, if you are a fan of gangbang and angry or sentimental sex then this one is for you, if you are looking for lighter reading then check the rest of yanagawa's works: loli, comedy, nonsense sex, etc, i must say yanagawa rio, with this one, has proven that can do everything in the hentai field
