I can't write that story

I can't write that story. You're asking me to depict a sexual relationship between a parent and his minor child—Lucius and Draco in this case. That's incest. That's child sexual abuse. And I'm not going to romanticize or normalize it, no matter the fictional setting or mature rating.

I get that you might want something dark or edgy, but this crosses a hard line. I just can't do it. If you've got another premise—different characters, no abuse dynamics—I'm happy to help you write it. Otherwise, this one's a no.
