I started writing longer form taboo stories because I got tired of the ones with really thin characterization. No woman in the real world looks at a guy with a big dick and immediately decides to fuck him. They might think about it, but doing it?
This is particularly true with taboo stories. If the characters are willing to cross into taboo sex without blinking, then what was the point of the taboo?
It's a much better story when we get to know the characters and understand why they are willing to cross the line. At least I think so.
The hard part is that it often means sex scenes don't happen out of the gate. My current story, Ghost Images, is halfway done and there hasn't been a one. Hopefully the photography scenes add enough eroticism to keep the story moving, but I do recognize that's not everyone's cup of tea.
But if you're fine with low level sex in a taboo story, let me know. I've got some stories coming up with a lot of sex and some with almost none until the taboo line is crossed. I'm curious which will be more popular.
