Based upon a drabble prompt on LJ's comment_fic 'any show, any pairing, 'forbidden''

It started with him calling her Witchy, and Judgy,
And her zapping him with aneurysms, and flames.

And then, suddenly, they were too riled/too close.

It should have ended with her threatening to maim him if he speaks of it again.
Or ended with him smirking and alluding to her 'gagging' for it only hours before.

It should have ended right there.

But it didn't.

He flies through her window,
...into her bed, again and again;
her nails digging into his shoulders
as he guides his fangs and his cock into her.

They've become... habit.

Marking/being marked.
Taking/giving.
Each others' forbidden secret
