Losing himself to the urges and erotic rushes of the transformation that flushed away his humanity further and further, Van Helsing could not let go of his own acking cock.
It felt like it was taking control of his whole body, altering it to please it's own will, shaping it to make Van Helsing a creature better suited to spread the dreaded disease.
Van Helsing kept rubbing his slick cock, dropping to his knees the same time. A small drop of pre-cum glistened on his pointed shaft and his own aroused scent fillied his slowly shapeshifting nose.
He hadn't been able to hunt and kill the infected dog. The beast had somehow undermined his already weakened resolve against the virus that had infected Van Helsing some days ago. Now the transformation was at hand and he could do nothing against it as it swept over his body like a tidal wave.
Still rubbing along his cock on it's full lenght, Van Helsing felt a orgasm comming up. He sped up his masturbation and started to whimper.
Kneeling on the garden's ground in front of the black shepard, whose cock was still fully exposed, Van Helsing's cock started to spasm away his last vestiges of human sperm in long, sticky shots.
Every load of sperm that shot out of his doggy cock started a gigantic wave of orgasms that exploded deep within Van Helsing's mind. And they kept comming and comming...
After what seemed to be a small eternity the cock slowed it's spasming and Van Helsing stopped stroking himself, dropping exausted to his hands in the following moments.
He was panting very hard and some last drops of cum dripped from his pointed cockhead to the grassy ground.
He only realised that something had changed as the scent of the shepard hit his nose with full strenght. The infected dog had come closer, positioning itself just in front of Van Helsing.
It's canine smells filled the transforming humans mind, activating further doggy instincts.
Slowly lifting his head, Van Helsing had to gaze upon the slick doggy cock that the shepard had positioned right before him.
It was fully exposed and smelt like heaven to him.
Without thought, Van Helsing slowly grabbed the dog's cock with one of his hands and placed his lips on the doggy member.
Tasting the salty cock, he slowly opened his lips and started to engulf the cockhead with his mouth.
New and arousing tastes filled his mind and he slowly started to glide his lips along the nearly full lenght of the shepard's cock.
Having lost the battle against the infection, Van Helsing kept kneeling beside the black shepard, licking and sucking the dog's cock, as a small nub emerged on his lower back. It slowly grew into a dog's tail.
Black fur started to sprout all over the man's body and his fingernails grew into claw-like forms as his hands transformed themselfes into paws.
Van Helsing did not notice all the changes and he did'nt care about them. His mindpatterns were fully changed into canine ones now and his only concern was the dog's cock and his own mouth to suck it...
