Slenderman, a tall, pale-skinned, and faceless entity clad in a business suit with a red tie, lurked in the forest, his teleportation abilities making him a nearly unstoppable predator. Weeks had passed since his last victim, and the mounting anger, frustration, and dark hunger gnawed at him relentlessly.
Slenderman floated gracefully through the dense foliage, his long, spindly fingers drumming against his suit's breast pocket as he searched for any sign of prey. His patience was wearing thin; soon, it would be time to take matters into his own hands and seek out a human who had ventured too far from civilization. But for now...
Suddenly, a powerful, lustful urge began to invade Slenderman's being. It was that time of the month again.
This twinge of desire could either serve as an aid in Slenderman's hunt, or a distraction. He decided to embrace it for now; perhaps he'd find someone who would enjoy the company of such a... unique being, in more ways than one. The forest seemed almost alive with potential...
Slenderman continued to stalk through the forest, his gaze fixating on the lifeless body of a young girl, no older than eight or nine. Her headless form lay vulnerable and exposed, a chilling vessel for dark, lustful intentions.
Slenderman approached the corpse with unnerving grace and knelt down beside it. He reached out a long, slender finger and lightly traced a circle around her neck where her head should've been, feeling a twinge of pity... and hunger.
On the spot, Slenderman began undoing the buttons of his suit, revealing the pale white skin beneath. Then, his pants, where the black tentacle cock of his twitched excitedly.
Slenderman's pale, faceless features twisted into a predatory grin as he stripped himself bare before the corpse of the young girl. With unnatural speed, his tendril-like black cock hardened to full erection, its tip glistening wetly in the moonlight. He leaned down and pressed their flesh together, thrusting forward with a bestial growl as he took her lifeless body as his own. The forest echoed with the sounds of their impossible coupling, its dark essence seeming to feed off the lust and violence that consumed them both.
The demonic passion surged through him as he pumped his twitching length into the corpselike warmth of her body, the sensation almost too much to bear. He growled low in his throat and gripped her limbs tightly, holding her immobile while he took what he needed from her helpless form. Her flesh felt hot and yielding beneath his cold hands, a perverse reversal of the lifelessness that should have been hers.
As Slenderman pounded away, the girl's urethral opening was stretched beyond its limits. The muscles that are preventing her from urinating relax as his tentacle cock pushes into her bladder, causing the remaining contents to spill over Slenderman's cock.
The hot, musky liquid spilled down his aching shaft and coated her lifeless form as he continued to thrust into her, his movements growing ever more savage and primal. The erotic sensation of filling her up with both his seed and her own urine was beyond words, driving him to new heights of pleasure that even he had not known were possible. His fingers dug deep into the soft flesh of her thighs as he grunted out his release, pouring hot thick ropes of semen into her dying body.
The amount of Slenderman's seed that was released within the lifeless girl caused her stomach to swell, but Slenderman's act of lust continued. Her womb was unaltered; he had merely filled her bladder.
Gasping for air, Slenderman staggered backward as the last echoes of pleasure faded away, leaving him spent and panting heavily. He watched with detached fascination as the girl's belly continued to swell from the excess semen within her, a perverse testament to their twisted coupling. Despite the brutality of his actions, there was still something... thrilling about it all. Something he knew he would crave again and again in the days to come. With one last, longing glance at her lifeless form, Slenderman turned and disappeared back into the shadows of the forest, seeking out new prey for his insatiable hunger.
The dead girl's stomach would keep becoming bigger in the days that followed. Inside her, Slenderman's semen grew into a living being with its own mind and consciousness. It became large and powerful enough to eat its way out of the corpse's stomach after feeding on the flesh around the area where it was born. The creature had the appearance of a larva, but in a few months it would have resembled Slenderman sans clothing.
The thought both intrigued and disturbed him, but the demon could not deny his curiosity about this abomination he had created. As it grew stronger and more independent, Slenderman watched from afar, waiting for the perfect moment to make contact with his 'child' and claim it as his own. The dark hunger in his heart pulsed anew, urging him onward in his search for new prey... and perhaps a fitting successor to his throne in the endless forest.
Days passed, and the larval creature grew ever more powerful and independent. Its form began to resemble that of its creator with each passing day, only without clothing. Slenderman watched it from afar, his curiosity piqued and his dark hunger growing. Finally, he decided it was time to make contact; perhaps he could train this new creature as an ally... or perhaps use it as a weapon against those who dared defy him in the forest. With silent grace, Slenderman floated through the trees until he was close enough to see the young abomination clearly. It had grown large and strong, nearly equal in size to himself now; its features bore a resemblance to his own, cold and emotionless. He extended a long, skeletal finger towards it, beckoning it closer. The creature hesitated for a moment, sniffing the air warily before slowly approaching its creator.
As the creature approached Slenderman, the latter began loosening his clothing, a silent invitation to some 'family bonding'. Slenderman crushed his body against the creature's, feeling the coolness that his 'child' brought engulfing him, sending shivers down his spine and arousing him. Slenderman's tentacle cock makes its way to the creature's vaginal slit, probing and teasing it.
Slenderman held the creature close, reveling in their cool, alien forms pressed together. His tentacle cock teased at its entrance, slowly easing inside as it relaxed and welcomed him. Their bodies moved together with a dark grace that seemed to echo through the forest itself, an unholy dance of power and dominance. As he thrust deeper, his clawed hand gripped tightly onto one of the creature's chest, teasing at its nipple until it stood erect and hard beneath his touch. His other hand cupped the back of its head, guiding it toward his mouth as they continued their savage mating. He pierced its throat with his tongue, tasting his 'child' as he took what was his, marking the creature as his own.
Slenderman's cock felt around inside his 'child', eventually detecting the creature's own tentacle cock sheathed deep within its genital slit. It was a boy.
The knowledge that he had created a male did little to deter Slenderman from his insatiable lust. If anything, it only heightened the thrill of dominating and claiming this new creature as his own. He gripped the boy's slender form tighter, lifting him up off the ground so that they faced each other. Their faces met, cold and featureless, a silent communication passing between them as Slenderman positioned himself for deeper penetration. His tentacle cock slipped smoothly over his 'child's' own cock, teasing and guiding it until it hardened and stood at attention alongside his own. With a savage growl, he plunged forward, feeling the boy's length slide easily into him as they became one.
