hi, a couple of months ago i stumbled on an intresting manga on my phone and forogot to mark it and i don't remember the name. Its definitely adult orientated I vividly recal three particular scenes the first where a military man or a spy (not sure) goes to a prostitute that poisons him and kills him . The second scene was in a biocontorlled dome and the third about a torture interogation where one of interogators was a female overly atached to the male interogator.

I would be thakful if someone can help me find it.

I don't know the manga you're describing, but these two possibly come to mind:

Beageruta (aka Die Wergelder)

Murciélago

Great, its the first one, thank you.
