He had metamorphosized again a week ago and so far had not regained his humanly form. He roamed the wooded areas around his neighborhood and waited to reappear as Michael Khaygyn, who he started out as over 50 years ago.

It was during that damned trip to Yukon, when his dog team toppled him over a cliff and he lay in deep snow with a broken leg, as his team lay dying. He snarled as he remembered the wolf pack that surrounded him as he and his team huddled together, knowing that his time was up. Suddenly they turned from him, and began to rip up his dogs, until there was not one scrap of meat left. Then, one by one they sat facing him, until a circle was formed around him. They watched him and it was as if they were waiting. But waiting for what? For a moment he thought he was hallucinating, that he was losing his mind and there was no wolves. For a long while they all sat, staring at him and he stared at them, unable to move or leave.

Then suddenly, as if by an unheard cue, they parted and a huge black wolf trotted into the circle and headed straight for him. As he quickly sat forward the wolf pounced on him and showed him two rows of perfect, two inch fangs, which glistened white, drooling clear saliva and emitting a low growl. He submitted and averted his eyes, knowing to do this much, as he was a smart man and had good animal savvy. Then the leader quickly gave him a once over sniffing and became very interested in his broken leg, which had bled some and had an open sore. The man groaned and knew that his end was eminent, as fresh blood was sure to send this giant into a chewing, eating frenzy. But instead the huge lupus began to gently lick his wound cleaning it and pulling on the fabric with his teeth to expose it more. Soon all the blood was cleaned away and only healthy pink skin showed. Then the wolf gave him a lick across the face and he noticed the wolf had a massive erection nearly dragging the snow. He bounded off to his pack. The females were all cowed before him, whining. Suddenly he mounted the largest female and drove his massive cock deep within her as they mated in the snow. Michael watched with interest as the wolfcock was at least 10 inches long and he was driving the entire shaft into the bitch. She looked as if she were grinning as he impaled her over and over. She yelped and he heaved into her again and then they were still. He jumped off her and turned his tail around and they locked this way for awhile. Michael began to get sleepy. They last thing he was aware of was watching them as they all disappeared into the snowy woods beyond. He was astounded and shocked. Surely I am dead and just don't know it yet. Perhaps I hallucinated it all. He drifted off to sleep and then awakened as rescuers lifted him onto a come-along and whisked him to a hospital.

He awoke in a room surrounded by flowers and cards. He quickly recovered and went home. Within a week he noticed the hair on his back and palms was more plentiful and he was horny all the time. He constantly jerked off his cock and as soon as he would finish, he was hard again. Then the first full moon came. He was sitting on his balcony and had just finished smoking a joint and the gut wrenching pain of the transformation began as he began to change, mutate. Some thing was driving him crazy between his legs. He sat back on his haunches and started licking his dick, licking his dick? How the hell did he do that? Suddenly he noticed he was on all fours, and his hands were paws. He bounded into the house and looked in the mirror and went crazy when he saw his reflection. He looked exactly like that wolf he met on his sled race that licked his wounds.

He ran outside and immediately went into the woods surrounding his property, in case anyone saw him. He had to sit down again to see what was wrong with his cock. It was completely out of the sheath, 10 inches long and hard as blue steel. He cleaned it off and it began to spurt and he began to hunch the air. He relieved the erection some, but it was still there. He suddenly knew what he needed to do. He needed to find a female to fuck. And with his size, he needed to find a big one. So his instinct took over and he began to search for a suitable bitch to sink his cock into.

He ran through the sparsely wooded area for awhile. Suddenly he caught scent of a female near-by. He crept forward slowly and watched as a young woman had a midnight swim in her private pool. His cock let down out of its sheath as she floated around and kicked her legs. Suddenly she removed her bathing suit and dove back in. His cock was raging and he had to fuck her. Stealthily, he crept up to where she was bent over drying her feet and stuck his nose into her crotch, and she straightened up and whirled around and saw her admirer and immediately turned to run and he was upon her, growling and snarling, teeth snapping over her face. Suddenly she grew very still and quiet as he put his teeth to her neck and growled. His snout moved down to her chest, and armpits and he gave them a cursory lick, but his dick was bursting and he had to bury it deep inside of her. He put his nose into her crotch and nosed her thighs apart as his long tongue began to explore her tender folds and tunnels. It thrust up into the depths of her and he nibbled at her meaty labia.

She was paralyzed with fear but the warm stirrings of her animal was coming alive inside of her, and she whimpered a little. At this he doubled his efforts and began to lick in earnest, ass hole to clit, tasting her and smelling her insides as she began to grow very wet and now she was moving her hips. His cock was about to burst, so he pawed at her to get her to turn over in a doggie fashion. She complied and was soon on her knees and hands and he was over her, front paws hooked around her waist, cock stabbing at her furiously, but only grazing her skin. He was frantically trying to fuck her but it was not happening. Suddenly she moved some way and his cock head was slipping inside of her. With a mighty shove his entire length was quivering inside her warm cocoon, and he began to push it in deep and pull it out and slip it in deeper each time. Her breath came in gasps and she started to push back against him and he could feel the walls of her pussy pulsating against his tool working inside of her. She began to moan and slam her ass into him as he drove it in as deep as it would go and then as the knot slipped into her, she pissed and came and screamed all at the same time. His knot was as big as an orange and was completely within her pulsating cunt as he pumped her full of his cum and turned to face out and let it soak in. She was in ecstasy herself and furiously rubbed her clit as she spasmed against his knot. She heard a distant voice tell her that this was not human she was fucking, but she didn't care. He made her cum like no other, human or not. Soon he slipped out of her and ran into the bushes before she could get another look at him.

And so it has been for the many years since. He turns into a creature once a month, seeks out females to fuck and they always act scared but then they crave it. All of the women want him to come back, as they leave out meat for him during a full moon. But it's not meat he craves. Well, at least not that kind of meat.

He needed something else..... He instinctively knows he must convert another human to this form so he can permanently retain his canine form, for he has come to love this form, a driving sex machine, and he loved to fuck human women. Especially unsuspecting ones who woke up with his probing wet tool deep with in them and they were writhing on him before they were even awake. He would sneak up on them as they slept and ease it inside and began to move and fill their sweet honey holes until they were crying out in pleasure, arching up their backs to meet his thrusts, and biting their own hands to keep from crying out and awakening the household. He would always slip away before they could really see him. But they were all most willing and very wet. And would coo and purr as he cleaned them after ward. Then he was gone. This was the existence he wanted forever. And tonight he would do it. He would never have to walk upright again, or work some mundane job. He could fuck human women and still be wild and primitive. What a life.
