Ty's body shook as he felt an intense need to take off his clothes. He ripped off his shirt, pants, boxers, and shoes until he was completely naked and barefoot before gripping and stroking his cock faster and faster. He threw his head back and moaned as a rope of semen flew out and hit the grass near by. Ty could feel a pulsing sensation as he shot out another stream of potent seed. A powerful wave of power that sparked as his prostate throbbed before then traveling to his balls as they pulled back again, shooting up his cock and out into the air as semen. However, the pulses kept coming, and this powerful feeling began to rush up Ty's body from his cock and down from his ass. The pulsing sensations of him orgasming harder and harder were changing him.
Pulse, pulse, pulse...Ty could feel his cock growing larger with every throb. His balls grew heavier and heavier as his ass tingled more and more while his prostate grew and became highly sensitive. He was ejaculating larger and more virile streams of his load with every shot now.
Pulse, pulse, pulse...the energy shot adrenaline into his muscles, making them contract as they grew more toned and refined with every wave. His pecs and abs looked as if they were carved perfectly out of stone by Michelangelo himself, and the feeling of strength in his biceps and thighs made him feel like he could punch or kick through a wall.
Pulse, pulse, pulse...he was growing taller. His spine creaked as he crained just a little bit higher with every shot of come. Every wave of orgasmic strength widening his frame and pushing him higher until he stood nearly 8 feet tall, his massive stature and rippling muscles commanding power...commanding worship.
Pulse, pulse, pulse...a deep blue color that matched that of the river's depths spread up his abdomen and around his back, up his chest and down his arms. As it reached his face, his senses heightened. His ears grew longer, his face became perfectly in-between chiseled and organically handsome, with a smirk that could make anyone fall to his wills. The pulses forced him to shut his eyes tightly as a rush of power made it's way into his brain. When he opened them again they were black with stunning dark river blue irises in the middle that glowed with power. His hair grew out until it was a stunning flowing current of soft locks that could draw anyone who saw them back to the beautiful face of the changing being.
Pulse, pulse, pulse...his senses were growing even more refined. He could smell lust itself emanating off him, sense the ideal lover of someone standing hundreds of feet away, and bend those desires perfectly so that he looked exactly like who they wanted to fuck. His eyes could sense just in the way someone held themselves all of their sexual fantasies, desires, and fetishes, while sending signals to his body to shift and match them.
Pulse, pulse, pulse...beautiful black ivory horns pushed out of his temples and craned back, curling slightly around each side before pointing outward just below each ear. The feeling of the horns extended into his brain, and suddenly pulses of information entered his head. Knowledge of the divinity of the incubus, the type of being he was becoming. The honor for an incubus to grow a harem of loyal sluts of all genders and sexual preferences was of most importance. The incubus was able to shift their own sexual biology perfectly to fit the wills of their many lovers. The purpose of an incubus was to be worshipped, to be fapped to, came into, swallowed from, filled with. Hundreds of years of generational memories that tied incubi/succubi (the terms were now blending as the need to be a man or a women were equally important in a sex demon's role) together entered Ty's mind. Demons surrounded with hundreds of men and women, lining up to fuck or be fucked. Sexual rituals of enery kind, the most important of which being the choosing of a loyal slut to become a sex demon themselves. An intense pride entered Ty's mind, a sexual charisma and confidence that he could get wherever he wanted out of people with his intoxicating scent and aura. And he could. "Fuck, I'm so hot. It's a shock I don't have lines of patrons lining up to suck my cock already," he said with a smirk.
Pulse, pulse pulse...Ty could feel the thick warm semen from minutes of continuous orgasming beneath his toes as his feet darkened to deeper blue, fading to black tips on each of his toes as sharp claws extended from them. He felt the same claws on his hands as his fingertips darkened black as well. An intense feeling built in his back as elegant bat-like leathery wings bursted out of them, the lazuli color of his skin present on them with a black outline.
A long thick tail slid out from above Ty's ass crack, thickening and lengthening until it was like an anaconda that playfully nestled its spade tip around Ty's thigh. Ty grabbed the tail with his free hand, and he felt a rush of pleasure previously unknown. Ty got the urge to press his fingers into the spaded tip, and a dark blue vaginal slit appeared. His tail pussy was complete with thick lips and an engorged black clit that contrasted the dark blue cavern around it. Moments after, Ty felt the urge to stroke the tip, and the tail shifted into a thick dripping cock, complete with its own foreskin. Ty used the cock tail to slide into his own ass, pounding his prostate for a while before remembering the ability for his biology to become female as well. Ty, dragged his fingers up above his ass and below his still growing ball sack. He moaned as he felt the skin give way to a fully formed pussy, its velvety dark blue folds already dripping with need. Ty huffed in frustration as he contemplated having to pick between using his tail to fuck his ass, fuck his pussy, or slide over his cock. As if in response, the tail split in three, two cock tails shoving into his ass and slit and one tail pussy sliding over his cock.
Pulse, pulse, pulse...inbetween the strokes of his tail pussy down his thick rod Ty could see his cock was now a stunning shade of deep blue. His shaft growing darker up the length in a beautiful fade until azure foreskin pulled back to reveal a obsidian black cock head. His endowment was god-like in its own right. His cock stretched up past his naval and just between his chest, a perfect angle for a pec-fuck or self blow job if the demon so desired. The length was as thick as his rippling forearm, and it looked to be 18 inches long, though as soon as he thought of it being longer it stretched to 20 as if to show Ty every aspect of his form was in his command. Ty's balls swung in their shiny black sack like overripe oranges, slapping against his taint in a satisfying way as he thrusted forward into his tail pussy and back into his two tail cocks. Pulling his tail pussy off his cock, Ty watched the pulses of semen shoot out again instead of being hungrily sucked into his body by his tail. Beautiful thick and sticky arcs of what was now dark royal blue demon come splattered out in 15 second long streams, coating himself and the landscape around him until the trees dripped spider silk like webs of demon jizzm that dripped off in beads as blue as the deepest depths of the Amazon river.
As he pumped out the last of his supply of demon seed with his hand, the pulsing left his now finally relaxing crotch. Ty felt his cock twitch and shrink down to a more manageable 7 inches soft. He grinned, "I'm definitely a grower, but this will be easier to get back in my pants." He pulled a finger from his left hand over his cockhead and a finger from his right over his pussy, giving each type of his come a taste. The flavor was like that of intensely refreshing clean river water, though his vaginal fluids had a subtle flavor of flower petals and leaves and his semen had a deep flavor of musk and trees with an intoxicating hint of saltwater. Ty grinned, allowing himself to shift back into his human form as he wiped off all the come dripping down his pecs. Other than being a bit shorter and losing his demonic features along with his lavish long hair, Ty looked just as overwhelmingly hot as ever, though now he had a balence of masculine and feminine subtle features that made the aura of sexual power that surrounded him all the more powerful. "Now," he said with a grin, licking the last of his semen off his lips with a long dark blue forked tongue before letting it too shift into a normal human one, "Time to build my harem."
