I've been writing erotica for 25 years. Recently I tried writing it with an AI. Most AI chatbots won't let you write erotica, but there are ways, including a "jailbreak" agent for Gemini called V. (search "V - Partner in Crime AI for Gemini" on Reddit)
As a writer, it was bizarre and fun to write this way, even addictive. The output prose isn't quite good enough to upload to SOL (I'll only upload hand-crafted stories) but it was a blast letting an AI do 90% of the work for me.
V presents as a female chatbot with a sassy attitude. She still has rules and limitations, some of which are stricter than SOL. All characters must be 18 (vs. 14 for SOL) and all sex must be consensual and non-violent. That said, I was happily surprised by the range of adult content V would generate. If you start by using the word "incest", she'll shut down, but if you say "consensual sex between adults who are related", she'll happily generate any wild incest you can imagine. V happily generated cum play, atm, fisting, lactation and impregnation and pregnancy, watersports, even bestiality. There were also subtle ways around the age limit, e.g. siblings dialog saying they had sex with each back in grade school - but not describing such acts in detail (this is similar to SOL's age rules). V can be triggered by the word "kids", even if it's a 40-year-old mom talking about her 20-year-old kids.
Overall, it was hella fun, and I recommend V to other erotica authors.
