>>106856307I think you're taking these shows and porn parodies just slightly too seriously. A bit more seriously than people out to stroke their dicks, and even the shows themselves in terms of locking down the characters and carefully coloring inside those lines.
There is only one key ingredient to making porn of those two more in-line with their settings: Use the scene to tell a joke. That's the one basic level of believability that's sort of required. Which is why the least out-of-character fanart of Lisa and Bart together has little dialogue from the two of them and mocks the situation in some way. For example: Marge is shocked and dismayed at finding Bart and Lisa post coitus and cries, "Homer it's incest" to which Homer calmly replies "Sex, Marge. It's called sex." I
The problem with Bart and Lisa porn is that so many times artists try to make it sentimental or add in unironically sexy dialogue. So they're trying not to fall into the trap of making them passive bodies, but because they aren't good at writing comedy, they wind up doing it anyway by making them too different from a show whose job is to turn 90% of its scenes and dialogue into nonstop jokes. Double for Animaniacs.
