While i really like romantic or semi romantic shit in tits, i can totally understand where you're coming from, and i agree.
You might be interested to know that Nonesuch, the guy who wrote the "demon domina" (Sera) is writing another dommy futa named Jasvalla. I'm a patreon of his, so i've read her character doc. She's basically an obsessed stalker who will ambush you on several planets. If you lose to her, she can drag you back to her ship while you're unconscious, tie you to her bed, and rape you. (Your character tries to get free of the binds during the scene, but can't) She will then try to get you addicted to her cum so that you'll be forced to be her slave wife/personal breeding machine. (assuming that you have a vagina, although she will encourage you to get one and give you tfs to do so if you don't) She's pretty close to being fully written now.
Might be a bit more up your alley.
