I'd fapped to Ladybug (and Cat) a few times before I'd ever watched the series. Just you know finding pictures that looked good in random rule 34 threads. I kinda had an idea of what the characters were like, base on what little I'd payed attention to stuff I'd seen, but really didn't know much.
Then I started playing that strip poker that has threads on /aco/ and Marinette became one of my favorite opponents. But her constant references to things like "Kwamis" and people like Alya or Hawkmoth went over my head. So wiki'd them and read up on it, and it sounded interesting. So I began watching it.
And now fapping to Ladybug rule is so much better, because I know the characters. I know what their personalities are. I know what they like and dislike and what's important to them. And I get the little references, some of which add so much to it. Like pic related. If I'd never watched the series, this would just be a guy in a latex cat suit, finger banging a chick on a roof top that looks like it could possibly be romantic. But having seen the episode (as well as all the rest) I know the importance and/or implications of this scene.
