celandineb prompted me with Harry/Hermione (or Harry and Hermione): random, dog, shout, and I wrote, Some Random Thing (R; Harry/Hermione; 100 words): It's far too late to say no.

They didn't make any declarations.

Soft skin, warm stubble, wet.

They didn't need a marriage license.

A push and pull without permission or negotiation: pounding like the blood in their ears.

They didn't want children.

"No dog, no dishes, no . . . no, oh, that's perfect."

Not together, anyway.

"Want to . . . to . . . shout about you, 'Mio—fuck!"

They wouldn't use pet names. Ever. It was a rule.

"Sorry, sorry, sorry," Harry murmured, into Hermione's neck.

She released his hair. "If you . . . don't want this . . . to be, oh! some random thing, only once, then—"

"Yes, yes." Harry stopped moving, stared at her. "Yes."
