You fall to your knees as you're knocked forward, pushed by a force at once internal and external. The wolf pushes off against the ground, forcing himself into your behind. His neck fuzz tickles at your anus as he slides into you, and you can feel his rough tongue lapping at your insides. Muffles emanate from your abdomen. You can't tell if he's saying something or just moaning. Moreover, you don't care; the sensation is driving you nuts. You don't even feel the difference between his neck and his torso as it slides inside you, as that whole area feels nothing but tingles. You can see your belly swelling in front of you, the imprint of the wolf's muzzle poking out your right side.

You wiggle your butt as he plunges ever deeper. He was cleaning you out completely, but you didn't know if he was just going to stop at that...
