Just stick you cock into her muzzle
From Create Your Own Story
Seeing as her muzzle is already at the perfect height and nearly touching your cock, you don't waste any time putting her mouth to better use.
Mounting the ninetail's face, you are quick to push your prick down her muzzle as soon as she opens it to probably ask what you are doing. Also pressing her own paws against her eyes with your paws, so that she won't be able to see you as well as keeping her from standing up.
Then you go to work, humping away at the ninetails mouth like there is no tomorrow. Enjoying her hot, wet mouth along with her tongue as it stimulates your cock with panicked and confused movements.
And after some time of simply humping and the sounds of confused whines you finally fill that muzzle of hers with your seed.
