If you are a writer looking to explore this niche, avoid the trap of pure content. Instead, build romantic storylines using these beats:

After an intense hardcore scene (e.g., forced orgasm or pegging), he cries. She does not stop or mock him. She holds his face in her clothed hands. This is the "I see you" moment.

No romance genre is complete without the "enemies to lovers" trope. Hardcore CFNM supercharges this.
