Well, I recently gave in after few days of trying the free version and this is what the game came up with (Femdom. Nothing really hardcore but there is some blood and orgasm denial. Nobody gets permanently hurt)

I switched to dragon model right after after the titfuck from Heather and the princess, if you want to compare quality of output, but the quality of output doesn't show how much micromanaging I had to do when using free model, with rerolls of nonsense, fixing actors, and telling AI pretty much exactly what I wanted it to do. What was really annoying is that it seems like the free model usually tries to go from insertion to ejaculation in a single texy generation, and with every sentence you need to remind it that no, you're not coming yet. Some of the stuff it came up with is... Impressive.
For example after this single line I got this whole paragraph:
> You say "I- I can give you my milk..."
"Give me your milk?" she asks as she stands in front of you. "Your what?"
"My... milk..." you say.
She laughs a bit as her hand goes to your chest, slowly rubbing as she leans in close to you, her lips touching your ear.
"No, no," she says, "Not that. Milk is what little babies drink. I want your fucking cum. I want you to cover my tits and belly with all the seed your balls can muster."
She slaps your belly as she walks around you. Your body trembles with every step. She stands in front of you again, grabbing your face and kissing you on the lips.
"I want you to beg," she says, "Beg for me to let you blow that fat load all over me."
You moan as her lips touch yours.
I recently experimented with using less of "> You say" or ">You do" and just putting what I have in mind into quotation marks and letting the AI figure out from the context that I was saying that. Same if I wanted other characters to act some way. The AI correctly interpreted my intend without explicitly identifying actors like 80-90% of the time. Using quotation marks in story mode also allows you to write more cleanly and lets you talk, when narrating without wrestling with AI for control, by doing something along the lines of '"So soft", you mumble as you squeeze her breasts."
From what I've read, longer, more complex sentences make the AI respond better, and too artificial speech pattern (like one you would use with old school chat bot), will result in subpar responses. Using this method helps you write longer, more complex sentences, that supposedly give better results. Altho It's othen interested to just give it vague 1-2 word commands, or just begening of a sentence and see how it's going to finish it.
Possibly because of my heavy use of world info end remember feature, and focus on some distinct characters, rather than random sluts/dudes, and saving all info as soon as I know I want to stick with it it is my best story.
Also, new stat system is pretty hilarious when used for player-dom smut. Tfw you are a succubus and you fail dexterity check, and slip, ramming dude's whole dick inside you.
As for technicality: Your input doesn't matter for the model. Nothing you write doesn't permanently affect the AI, and it won't remember that it ever existed as soon as it leaves the input range (At least directly, the fact that AI uses the connections to generate the content might cause same connections to work backwards, and make it slightly more likely to make up same thing again) Or at least that's what I heard from people who seemed like they knew what were they doing.
