I wish there was a tag for this specific kind of scenario that kiliu excels at. It's this specific cross between chikan, rape, forced exposure, hidden sex, public use, moral deg/mind break, emotionless, etc., yet is not properly captured in any of those tags.
It's the way the women protest/reject so consistently, react so nonplussedly even when they're not clueless. Yet, not just simply allowing it to happen, they will always immediately begin to reciprocate with the rapist(s) even when they ARE clueless, to the point of willingly doing obscene displays of debauchery themselves (condom play, oral collection display, clean-up blowjobs, etc etc). Sometimes it even immediately preceds a panel/page where they internally complain about what happened while returning to their original banality, to great comedic (and erotic!) effect, practically daring the reader to doubt their own lying eyes.
...or maybe there is a tag for this that I just overlooked on all of these galleries Kiliu galleries?
In any case, other than that one pair of books by Ranchi Kibun, I haven't found anything else that scratches this itch so reliably. If anyone has any recommendations, please share.
