While his body was changed to a new and better shape, Van Helsing could not let got of the shepards cock. He sucked and licked it, totally absent-minded and without further thought on his lost humanity.
His whole body was already covered in dark fur and his legs and arms were shaping themselfes to a dog's legs as the sheperd's cock started spurting sticky semen down Van Helsing's throat. He gulped all the sperm he could and his body tingled in lust as he did so.
Van Helsing's face extended into a sheperd's muzzle, his teeth sharpened and his ears shaped themselfes to a pointed shape. His transformation was complete.
Licking clean the other dog's slick cock, he realised a raised sexual tense in his own body. The other shepard had enjoyed his attention, now he had to exept Van Helsin's own need to mate.
His body tingled with exication.
He had to release this sexual urge that build up in him again, just as the virus that had just changed his body to a new shape demanded.
Letting go of the other shepard's cock, Van Helsing positioned himself just behind the other beast. He had no problem moving this new body at all, as the virus had rewritten all human mindpatterns and replaced them with all doggy ones. It was like as if he was born as a dog.
Van Helsing stuck his cold nose under the other dog's tail, right to the other animals butthole. It smelt like heaven and the newly transformed Van Helsing learned as much about the beast in the whim of a second as he would have talking to a human in weeks. It was just incredible.
The shepard let him go without reacting much, but Van Helsing's nose told him that the other dog was just about ready to accept every sexual action he had in store for him.
Without further thought, he licked across the other dog's butthole, lubricating it with his warm saliva. The shepard tasted great and Van Helsing felt his own exposed cock throb in expection of the things to come.
Then he jump-climbed upon the other dog's back, grabbing the beasts hip with his fore legs and moving his own body closer to the beasts butt with his hind legs.
His cock dangled between his legs and Van Helsing could feel it's need to release it's load into the black shepard beneath him.
Pusng his groin forward, his cock missed the other beasts hole just once until it hit the spot.
Without further thought Van Helsing drove his member deep into the anal tunnel of the animal beneath him, growling in doggy lust as he did so.
His hips started to push his cock in and out of the shepard's ass by instinct as Van Helsing's mind got carried away by the arousal that flushed thoughout his body...
