Doa girl sleep rape
Dead-or-alive girls getting blackmailed makes for a hot story in hentai manga. Humiliation of proud fighters and their subsequent rape is hot. Like this hot doujin featuring hitomi from DoA. The doujin's been English translated and all, and has a nice blackmail theme. Should make for a great read.

In some of the hottest DOA doujing, everyone in the female cast is a slut who enjoys bukkake and blowjobs. A doujin with a slutty DOA cast is great to read, particularly if the artist knows his (or her) stuff.
 
 
Ayane and Kasumi fucked from behind.
A common theme in many Dead or Alive hentai doujins is having the entire female cast participating in orgies or gangbangs on an island. The cast is usually mind-controlled into enjoying the sex. Some, like survivor, have a great mind-control story. Usuall, one or two members of the cast are left without mind-control and are turned into sluts by the end of the story.
 
 
Kasumi getting raped on the lust vacation island.
Hentai involving  characters from the Dead or Alive games is very popular, mainly because the stars of the show are very sexy and wear great outfits. A very common theme is DOA hentai is to have the girls from the series raped or having sex on an island. This CG set of Kasumi getting raped on an island(though she loves it in the end) is a good example. Kasumi in a bikini is a real treat.
