"Was it necessary to come today?" asked a wolf, leaning his neck to get close to the ear of a fox sitting next to him.

The vulpine listened to his companion, grabbed a napkin from the table and wiped his snout, "Can't you hold it in a while longer?" he replied discreetly.

With growing nervousness, the lupine straightened up in his chair, grabbed a glass of wine and drained it in one sip. His heart was beating faster and faster, the hairs along his body were slowly bristling , his fingernails were growing, and the fangs in his mouth were beginning to feel uncomfortable.

"Mike...It's starting," the wolf whispered back to the fox.

Mike heard the lupine, made a startled gesture and said loudly, "Your sister?"

Everyone at Mike's table and at the adjacent tables instantly diverted their attention to the fox and then to the wolf.

"Y-Yes...it was a slight bump but...she's been hospitalized anyway," the wolf stammered, trying to keep his composure to make the performance seem real.

"Ooh! George, dear! What happened?" asked a hippopotamus in a frightened tone.

A pair of phalanges crunched in George's left hand, making the male straighten his back, "My sister had a car accident..."

Mike stood up and took the wolf by the hand, "I'm sorry, Clarice, but we're her only family in town."

Clarice, the hippopotamus, covered her mouth with both hands," Oooh, honey...you don't need to give me any explanations. Just go and I hope everything turns out all right."

George rose from his chair as he was pulled by the fox, "Clarice, I'm sorry we have to leave. Please finish your birthday well," the wolf said, waving goodbye to the woman hurriedly.

The moon was shining brightly in the sky as the couple climbed into the car and buckled their seat belts. George had loosened his tie and unbuttoned his shirt, one of his eyes was visibly larger than the other, his legs slowly swelling as dozens of bones thundered inside him, fingernails elongated shredding his fingertips.

"Easy, there's a campground nearby that no one uses this time of year," Mike said, starting the car.

A couple of small teeth fell into the car carpet, the wolf's snout was growing long and wide, his shoes cracked.

As Mike drove down the dark road, which had huge trees on both sides, he reached out his right hand to help his boyfriend remove his shirt before the growing musculature of his arms tore it apart. As he removed the garment, the wolf growled and tried to bite at the fox's face, but the vulpine quickly dodged the attack and slapped the lupine hard, "Behave, you idiot!" yelled Mike.

The wolf covered his face and whimpered, going quiet as his transformation continued, growing his chest and creating a long straight line of darker colored fur that started between his pectorals and descended to his crotch.

The wheels of the car screeched as the fox turned sharply at the sign indicating a camping area. Mike accelerated to full throttle and having moved several hundred yards off the road, he stopped the vehicle, opened the passenger side door and turned off the engine.

George jumped out of his seat and rolled around on the ground, finishing tearing what was left of his clothes and screaming in despair as his body continued to grow. Mike unbuckled his seat belt, slowly got out of the car, leaned against the hood, lit a cigarette and stood watching the wolf transform into an uncontrollable beast.

When the metamorphosis was over, George stood still, panting and on all fours, his whole body was sweating, a strange steam was rising from his back, and his huge chest was enlarging and contracting as if it were a huge balloon. A few minutes later, the beast began to move and its first action was to raise its snout to the sky, open its jaws, and let out a powerful howl that shook the windows of the car and dozens of flocks of birds rose in frantic flight from all the trees around.

Mike finished his cigar, threw it on the ground and stomped on it, then slowly walked over as the wolf calmly lowered its head. The fox stood in front of the monster and slapped him hard across the face, causing the wolf to immediately lower his ears, let out a whimper and wag his tail excitedly.

"Feeling better?" asked Mike.

George nodded his head, ran off and disappeared into the darkness of the forest. The fox smiled, walked back to his car and sat in the passenger seat, putting his feet on the campground floor, then pulled out his cell phone and checked his social media.

Mike had been paired with the wolf for six years and they both loved each other despite George's strange condition. The first time the fox met his transformed boyfriend he thought he was going to die, the terrible image of the huge beast, which was twice his size and weighed, had left him frozen in terror, but nothing bad happened, in fact the fox stayed sitting on a cardboard box in the alley where he had been caught, while the wolf stayed curled up next to the vulpine as if it were a giant dog, growling at anyone who walked past them.

Loud footsteps echoed in the night, and a heavy object fell a few meters away from Mike. The fox turned on the flashlight on his cell phone and pointed in the direction the sound had come from, there he saw a huge deer with its throat slit and next to it was George, sitting on his backside with his muzzle stained with blood, his eyes shining in the light of the flashlight.

Mike got up again and walked over to his boyfriend's prey, "Well, at least this time it wasn't a person..." said the fox raising an eyebrow.

The big wolf jumped up in excitement, let out a bark and presented his butt, raising his tail in front of the fox who could clearly see the beast's huge anus and heavy testicles.

"Now? But we did it while we were bathing before coming to the party," Mike said.

George groaned, lowered his ears, lay back on the floor and lifted his tail higher.

Mike snorted and unzipped his pants, sticking his penis out in the open, "Fine...but don't expect too much, I'm not in the mood," the fox clarified.

The fox walked over to his boyfriend and knelt behind him, began to fondle the wolf's huge balls and then spread the beast's firm buttocks apart. George's anus was a large, fleshy and somewhat swollen hole, it was an ass that was quite used to being penetrated. The big wolf moaned as he felt his boyfriend's little tongue back there, and then it was followed by the fox's muzzle.

When Mike finished lubricating George, he stood up again, grabbed his penis, aimed it at the wolf's hole and plunged it all the way in without feeling any resistance. The sensation was fantastic, getting his penis into that soft, warm sleeve had become one of the vulpine's favorite activities. In fact, something the fox enjoyed so much was the sensation of being with two people at the same time, as the difference of George's body in his normal state was huge in relation to the beast's body.

The penetration was quick and rough, slowing down only when Mike's knot swelled fully, causing the fox to have to press hard to enter and push with both hands to get out of the wolf's insides, producing an obscene 'plop' as he repeatedly overcame the tight ring of lupine flesh.

Mike's legs quivered against George's massive thighs before shooting his warm semen into the huge beast's bowels. Pulling his cock out of the wolf one last time, even the knot came out with ease accompanied by Mike's flaccid length, completely drenched in saliva and other juices that formed a slimy bridge between the phallus tip and the freshly used hole.

The fox grabbed his member and wiped it against the fur of his boyfriend's buttocks, stowed it in his underwear and pulled up his pants, spanked the huge beast and started walking back towards the car.

But before the fox could get too far away, George twisted, ran on all fours and blocked his path, lying on his back on the ground, exposing his giant manhood hanging outside his sheath like a long, veiny sausage.

"Can't you jerk yourself off?" growled Mike.

George whined, wiggled his hips to jiggle his thick bone, lowered his ears and looked up at his boyfriend with puppy dog eyes.

Mike snorted, went back to kneeling beside the big lupine beast, grabbed the phallus with both hands and began to suck it, swallowing the copious salty pre-cum. The fox did not try too hard since he knew that when his boyfriend was transformed his heartbeat much, much faster, accelerating all his actions, reflexes, and stimuli.

The wolf's thick, long penis had always caught the vulpine's attention, while George was a fairly submissive male with both bodies, Mike always wondered what the experience of being penetrated by that huge hunk of meat and the coarse amount of lupine cum those heavy balls produced would be like.

"Hurry up...Uff I don't want to stain my suit...luckily we didn't get to eat anything," Mike complained before continuing to suck, taking in only a few inches of the gargantuan penis. 

George gritted his teeth, tensed his arms and legs, and gave a sharp thrust with his hips. That was the cue for Mike to take a deep breath just in time before he felt the thick stream of lupine semen at the bottom of his mouth, which fell like a viscous, salty waterfall, which was succeeded by eight more shots that coursed through the fox's insides until they lodged in his stomach, distending Mike's abdomen slightly.

The fox finished swallowing his boyfriend's sperm, stood up and wiped his muzzle, "Go take one more walk in the woods, I'll wait for you in the car," the vulpine ordered.

The wolf gave a loud bark of joy and ran off into the darkness. Mike sat back in the passenger seat, with his cell phone in one hand and the other caressing his swollen stomach, that warm lupine soup felt so good inside him, plus it helped him fight the cold night wind.

About an hour later, the wolf returned, his fur was clean and somewhat damp. Mike, upon seeing it, opened the trunk of the car and ordered him to put the deer in there, that freshly hunted meat would be good for several meals. He then opened the back door for the beast to climb in, making the car lean over.

Watching his boyfriend settle into the back seats, Mike sat in the driver's seat, buckled up, started the vehicle and began his journey home slowly, measuring the time until the transformation was over and enjoying the soft silence of the night.
