The rain poured down Interstate 5, one of the major highways in the western region of the United States. The road was calm in the middle of the night until the load roaring sound of a motorcycle passed through, vibrating in the core of those in the way. An orange headlight was the warning before the thunder, the motorcycle sped along with flames spilling from the four long chrome exhausts. The motorcycle was massive, a foot wide and five feet long, with two wheels paired at the front and a huge one at the back, covered in black metal with shiny chrome.
Scott had his hips wide open given the width of the motorcycle and he continuously thrusted his massive cock into the leather seat, each thrust was a bit deeper and a bit faster. Inside the seamless black helmet, he moaned and groaned at a tentacle sliding in and out of his mouth. His head was bobbing eagerly. Scott had become quite eager that he tilted his head to change the angle of attack.
{Almost, almost so we become truly one... Feel the engine, the pistons thrusting in, match it and duplicate it...} the sinuous voice made his flesh ballooned and bulged, veins pulsing as it still grew larger.
Without even really trying to, Scott started to gyrate his hips a bit, applying more pressure. He moaned, grunting hard, feeling his heartbeat in his cock. At the same time, he squeezed the motorcycle as he dodged each car to go even faster, to thrust deeper.
What started as an instinctive, impulsive, empty, subconscious act of sexuality on Scott's part, started to become reciprocated. Fenrir could sense the rider's soul giving himself up to become one. Scott moaned when he felt his blood drained into the suit, turning the black leather into a vibrant red, at the same time, he felt the tentacle he had been sucking for so long plunged tightly against his mouth, stretching his lips to their maximum.
The young man's back arched, a muffled moan escaping his plugged lips when a black metal hump formed on the back of his suit, with several fin-like protrusions for better aerodynamics. His helmet formed molded horns following the curve of the helmet and two small chin spikes curving down on either side.
"Ahg..." Scott groaned and panted. He looked below and he loved his figure.
Scott plunged his cock inside the tight sleeve and hugged the machine squeezing while he cruised every curve of the highway, dodging the slower vehicles by turning all his body down to the road on the pronounced curves. As he passed the vehicles with ease, the figure could sense more than he thought through his visor, he could see each driver. Their muscle legs pressing down the gas, their asses sitting down the seats. Their shoulder and arms muscles.
{Make them pull over and beg for your cock} Fenrir whispered. Scott made the engine roar as he thrust even harder.
Some drivers watched now and they could not stop ignoring the rider's suggestive movement of thrusting into the motorcycle. In fact, the rider's thighs and quads hid how his cock slid out and slid back into the seat. However, just the rider's physique and the motorcycle roaring sound was enough to stir the crotch of the men around. It was a powerful aura, some may even call it unholy. It was not a surprise some drivers crashed on the highway while staring.
{Deeper... Get into their brains...} the sinuous voice echoed into the rider's mind. Scott could feel his motorcycle in his head, how playful and tough it was, and how much it loved being used. The feeling was infectious
It all just drove the rider to thrust harder, in fact the rider and the machine were turning into one being, the rider could feel the asphalt underneath the tire, the force of the wheels spinning and the brakes burning against them, but especially how it clenched his cock for his seed, he felt the thrusting and the sucking at the same time. The motorcycle could see through the rider's visor, feel his inhibitions, fears and thoughts. The revolutions of the engine were at par at his heartbeat, they were one whole being after all.
{Pull over and make them ours, Vengeance} The dark voice echoed in the rider's head, as he saw the males around, mostly truck drivers.
"Vengeance?" the rider whispered at how the motorcycle called him. That name it felt so real, it felt part of him. No, it was him. He no longer was Scott. He had turned into his masters emotion of Vengeance to the world.
Scott/Vengeance moaned when he felt the red leather over his ass rippled and started pushing deeper into his ass, reshaping slowly into a perfect copy of his own member. The rider inhaled sharply as he was filled, his ass stretched over the rod invading it.
"Yees..." the rider moaned.
However, that was not it, the red leather at his tailbone grew in at the back, releasing a thick tail, it soon wagged behind him. There were small spikes on the tail, but the spikes grew thicker and taller. The tail helped him to gain momentum, driving his cock further.
"Soon we will find a worthy drone," Vengeance grinned inside the helmet, as he thrusted the bike more vigorously. In exchange, the phallus in his ass pulled back almost all of the way out. Vengeance tried a quick down and up and the cock matched his movements perfectly.
{We must bring out the deviant, turn them into loyal drones hungry for your seed} the voice whispered,
The demon in the bike was bringing Scott wilder, far more inhibited and far hornier. The bike and suit just filled him with images of drones besides him, worshipping his cock and conquering the roads, and corrupting the innocents.
{Don't waste more time...!} Fenrir roared in anger as he squeezed harder Vengeance rod inside, meanwhile the rod on his ass pushed into his core, swelling breaching human limits.
"Ahgg..." Vengeance moaned loudly in pain, he lost control of the bike, and began moving wobbly for a few miles before he gained strength again.
{We must mate, share our seed until Master fills us again} the voice echoed as he reached new speeds on the highway.
"I like it when you are angry," Vengeance replied back as he smirked.
Vengeance lifted the front wheels machine off the ground as he pushed his cock deeper inside, almost placing the tip to the cylinder's chamber. Suddenly, his cock spewed an enormous load of cum into the motorcycle's engine. The fleshy pad at the end of sleeve absorbed it all and then sucked on the head of his cock for more.
"Ahgggg..." Vengeance roared, still with the motorcycle riding solely on the back wheel.
