You cant resist the burning between your legs as Duke's dog-cock becomes fully erect inside your muzzle. You release it and turn around, backside facing Duke. He wastes no time and his front paws are immediately on top of you, "Now, to make you my bitch forever!"
He rams his shaft deep into your pussy and give out a yip of surprise and pleasure as he begins to hump you. "Ohhhhh Duke!" you manage to cry out between uncontrollable yips of pleasure.
"You like it don't you Bitch?" Duke says with a mocking grin. The human part of your mind is screaming at you to get him out of you and run before Duke's not inflates and locks you both together, but can you do it. As this passes through your thoughts Duke asks mockingly, "want me to go faster?"
