The Taste of the Hand Ch.1-15 (English) (Ongoing)

is there someone know ? what korean manga has a strong sexual graphics like a gangbang, bukkake. DP, rape, blackmail or similar to that. Cuz so far i read 10-15 of them none of them are good enough to be qualify as a hentai like hentai manga from jap i've read all this times. They're to clean, to neat, to safe, to afraid, to moral, to small if it compared to jap hentai. Of course they have sex in there but the fantasies they made are just small tip of jap hentai. Their advantages only in color & story when it comes to that things and it getting better they end it right away.....where is the fun of that ? What's the point of long story if you end it so quickly.
