Everything! As an erotica writer, I want to cause as much vasocongestion through arousal (in other words, blood running down to the genitals when people get excited) as possible. And, I'll admit, it's also a feeling of power to create that in people.
What are you working on next?
My main thing I'm going to be writing is violent femdom erotica, particularly girls/women beating up and beating down boys/men, with lots of ballbusting. That said, I intend to publish other types of erotica, a romance novel and political and socio-cultural blogs.
