OK, more weirdness coming from my dememnted imagination...

Anybody else think that in a chloroform scene when the villain surprises the heroine from behind, it would be really hot if the villain groped at her breast? Pretty quickly she won't be in a position to protest after all...

This happens a lot. Usually, the assailant will grab the stomach area of the female, really close to the chest. In an episode of Wonder Woman (the Feminine Mystique), Wonder Girl was grabbed from behind and chloroformed. The villain had his hand like right under her chest. Debra Winger never looked so hot.

OK, I'm gonna really cross the line now, or rather take a running jump over it. Has there ever been a scene where the villain has felt up the breasts of a KOed heroine? Like felt her up after she's unconscious? Would be awesome of it was combined with kissing the knocked out beauty on the lips...

I really can't say for certain, but there probably is one. Just browse the database...(hint: look at Doujinshis!).

Yeah there are, but they are mostly just porn comics and these arent shown on this website. Like Red says, they're mostly doujinshi's

Makes sense. I don't think I'd like it appearing in a mainstream comic anyway to be honest. Like if it happened to Ms Marvel for instance I'd probably be turned on but at the same time I wouldn't like them doing it to the character.
