Writing a new type of couple

[seeria]

I am looking for a new way to make sex rough. im thinking a few ideas....


Sex in a world controlled by elements: A young woman and man both controlling a different element take interest in one another. Fire, ice, wind, and eath used as fourplay.

Heaven's speechless: a young female half angel and young male half demon fall for each other but find consumating their relationship to be kind of painful and rough. Still, that can be fun.

any similar idea. Im a female looking for a male partner
