For me it's preciesly the oposite, and I'm picky, even petty. If they feel pleasure during the attack is an instant back button for me.
Not for any moral reasons, I just hate it when the victim enjoys it because I just want to see absolute pain and terror, no conflicting emotions or the victim getting mind broken or dick obssesed later. I don't even like reading real anecdotes of this because too many end up like "and I loved it, I became a total bottom bitch after it, would do it again." and it retroactively ruins the fics I like to read lol (told you I'm petty). Tho I don't know how many of those irl experiences are real or just people writing fantasies.
I'm fond of the victim getting injuries that won't let him focus pleasure. Like, break his bones, rip a limb off, have his skin burned, or the perpetraror being an alien/monster with barbs on the dick, anything as long as he doesn't enjoy it or cums out of it.

Short answer; I look for pain, fear and despair in the victim in a noncon fic. ... and delicious drama too.
