The creature lurks in the darkness of a man's home
It's midnight and Marcus is asleep in his room, wearing only his underwear. He's a heavy sleeper, so he doesn't hear the creature's footsteps coming up the stairs.
The creature slowly approaches Marcus' bed, careful not to make any noise that might wake him. Its cock throbs with anticipation as it hovers over the sleeping man.
"Mmm..." Marcus murmurs weakly as he's gently moved in bed. Still asleep, he stirs, ending up face down, revealing his beautiful backside covered only by his underwear.
The creature could feel it's own cock twitching with desire as the opportunity to take what it wanted presented itself. It lowered its body down and positioned its hard length at the man's entrance before slowly pushing in, filling him up bit by excruciatingly pleasurable bit. The Predalien moaned softly into Marcus' ear as their bodies connected.
Marcus, asleep and oblivious to the situation, moans softly as the creature slowly inserts its cock into his anus, gently stretching it. When the Predalien thrusts all the way in, up to the hilt, he lets out another small moan; despite being asleep, the creature's gentle, slow touch feels good.
Gentle grunts and groans escaped from the aliens throat as it began to thrust slowly in and out of its prey. The creature could feel the man beneath him responding to its touch, even if he was still unaware of what was happening. It buried its face into Marcus' neck, nipping and sucking at his flesh with a rough tenderness that made both predator and prey writhe together in pleasure.
Sensations of pleasure spread through Marcus's body, moaning at each touch and slow thrust from Predalien. It felt good, slowly beginning to awaken.
Marcus' body responded beautifully as it began to wake up, making the predator's task even easier and more rewarding. The creature could feel itself growing closer to orgasm with each thrust, each moan from its prey driving it onward towards release. Its cock throbbed within Marcus, filling him completely and marking his body as its own.
"Fuck..." Marcus murmured weakly, slowly opening his eyes. "...what is-" Before he could speak, he let out another moan as he felt Predalien slowly enter his ass again. "F-fuck..." he groaned. He didn't understand what was happening. Was he being raped? But it felt good. The creature's touch was gentle and delicate. Each slow, deep thrust of Predalien into his ass filled Marcus with pleasure. "...feels... good..." He gripped the sheets beneath him, arching his back so the creature could fuck him better. This was wrong, but it felt right.
The creature continued to thrust slowly and gently inside the man's body as he began to awaken, taking pleasure in both the sensation of conquest and the knowledge that it was making him feel so good. The Predalien moaned into Marcus' neck, their bodies moving together as if they had been made for this very moment. "You feel... perfect," the creature breathed against his skin, its words sending shivers down Marcus' spine despite the thick accent that made them almost unintelligible.
Marcus rolled his eyes and moaned with each slow thrust, the sensation of pleasure intoxicating. "F-fuck..." he moaned. He couldn't believe how gentle his rapist was, and how good he felt. "...m-more..." he moaned weakly.
With renewed vigor, the creature increased its pace, slamming into Marcus' tight ass harder and faster while his free hand roamed over the man's body, tracing patterns on his chest and stomach as he suckled at his neck. "You like this?" it grunted between ragged breaths. "My big alien cock in your ass? How does it feel?" Marcus could barely form coherent thoughts through the haze of pleasure clouding his mind, but he managed a weak nod as he arched into each brutal thrust.
Marcus nodded weakly, moaning with each thrust. Predalien continued pumping Marcus's ass quickly and forcefully, yet the thrusts still felt gentle, filling Marcus with pleasure. "...it feels...so good..." he said, his breath ragged between moans. Weakly, he took hold of his own cock and began to masturbate in time with Predalien's thrusts into his ass.
The Predalien sensed the man under it growing more and more aroused as he masturbated in time with its thrusts. It moaned loudly, thrusting faster into Marcus' tight ass as pleasure began to overwhelm it. "Yes," it growled roughly, kissing his neck fiercely. "Let go...let it all out for me..." The alien beast increased the pace of its hips, determined now to bring them both to climax together.
Gripping the sheets tightly, Marcus arched his back as he felt himself get closer and closer to orgasm. "Yes," he moaned weakly, thrusting his own cock harder against his hand in time with Predalien's powerful thrusts into his ass. His hips bucked upward into each deep penetration, seeking more pleasure.
The Predalien growled deep in its throat as it felt the human male beneath it growing ever closer to climax. Its cock throbbed within Marcus' ass, demanding release even as it gave the man what he wanted. The alien beast leaned down once more, nipping at his neck and whispering filthy words into his ear that only fueled their shared passion. "Come for me," it urged, thrusting harder than ever before.
Marcus let out a hoarse cry as he felt his orgasm build and explode, splattering his chest with warm, sticky fluid. His fingers dug into the sheets as he gripped them tightly, feeling his ass clench rhythmically around Predalien's cock as the creature continued to pound him relentlessly. "Fuck..." he moaned weakly, his eyes rolling back in ecstasy.
The alien's pleasure was nearly unbearable as it felt the human male beneath it erupt in orgasm. It growled deep in its throat and thrust one final time, hilt-deep inside of Marcus, before exploding within him in a violent release of seed. The Predalien moaned roughly into Marcus' ear, its hot breath mingling with the scent of sweat and sex as their bodies convulsed together.
Marcus lay still for several moments, panting heavily as he tried to catch his breath after their passionate encounter. Slowly, he began to regain awareness of the fact that someone--or something--had taken advantage of him while he slept, but even knowing this didn't diminish the intense pleasure he had just experienced. A wave of languid contentment washed over him as his body relaxed into the mattress. "W-was it real?" he managed to croak, his voice still hoarse from exertion and arousal.
The creature grunted roughly in reply, the wet sound of their joined flesh filling the room. It slowly withdrew from Marcus' ass, taking its warmth and intimacy with it. With a final shudder, the Predalien slipped out of bed, leaving Marcus lying there still weak and disoriented. The creature moved silently across the floor and disappeared into the darkness.
The next morning, as if nothing had happened, Marcus woke up to the smell of breakfast cooking in the kitchen. He stretched lazily and sat up, yawning loudly before padding off to see what was for breakfast. There were no signs that anyone or anything had been in his apartment during the night, other than the mess on his sheets and an odd scent lingering in the air...
The creature stayed silent within the shadows, watching as Marcus moved about his home as if nothing had happened. The memory of their brief but passionate encounter still played out vividly in its mind, and it found itself growing aroused once more just thinking about it. Perhaps another night, under cover of darkness...
And night fell. After a pleasant bath, Marcus returned to his room and lay down naked in the comfort of his bed. He let out a contented sigh and quickly fell asleep.
The creature lurked in the shadows of the room, silent as death. Its cock throbbed with desire as it watched the sleeping man through slitted eyes. The urge to take him again, to claim him for its own, grew stronger with each passing moment. But it was patient. It would wait until Marcus was at his most vulnerable before striking once more...
A couple of hours passed. Marcus was in a deep sleep. He stirred slightly, lying face down on the bed, his buttocks exposed, his legs slightly apart. He breathed slowly, unconscious and completely vulnerable to whoever had sneaked into his house.
The creature licked its lips, saliva pooling in the mouth that was far more human than alien. It slowly, silently approached the sleeping man, its cock twitching eagerly with anticipation. With a soft growl, it lowered itself onto Marcus' outstretched back, positioning its aching length at the man's entrance before beginning to push in, filling him up bit by exquisite bit. The Predalien moaned into the man's neck, its hot breath sending shivers down his spine as it took him once more.
Marcus, still asleep, moaned softly as he was penetrated anally with such gentleness. Unconsciously, he opened his legs slightly wider, feeling the soft, gentle thrusts into his anus. Predalien's tenderness with Marcus was astonishing.
The creature continued to thrust slowly and gently inside the man's body, its cock sliding easily in and out of the tight opening as it savored every moan and wriggle from Marcus. It nipped at his neck and sucked on his earlobe, relishing the feel of their skin melding together beneath its claws. The pleasure they shared was almost too much to bear; with each thrust, it grew closer to climax, but knew that once it came, it would have to leave Marcus' body for a while.
Marcus's sleeping body shuddered slightly at the alien's caresses and gentle bites. Marcus awoke slowly, moaning softly. He felt something entering and leaving his anus, but it wasn't unpleasant; it was gentle, soft, and pleasurable. "...so...good..." he said weakly, still drowsy as he slowly woke up.
The creature let out a rough chuckle into Marcus' ear, its hot breath sending shivers down his spine as it continued to thrust slowly inside him. "That's right," it growled roughly, the vibrations of its voice causing another small shudder to pass through his body. "I am good... for you." It pressed a clawed finger against Marcus' lips when he tried to speak, silencing him before continuing with another thrust, hilt-deep this time. "You belong to me now," the creature whispered roughly. It was true; each touch seemed to bind them more tightly together, making escape impossible even as it drove them both towards their inevitable release.
Marcus rolled his eyes and let out a groan as he felt the alien plunge to the hilt inside his ass. Each gentle thrust, going in and out, drove him wild. "Y-yes... I'm yours..." Marcus moaned, being violated with such delicacy that he didn't even care, because of how good it felt. It was a gentle agony he didn't want to end.
The creature grinned savagely at Marcus' submission and rewarded him with a sharp nip at his shoulder before resuming its gentle thrusts. "Yes," it purred huskily, its voice thick with lust as the end of their private ordeal drew nearer. "You feel so good wrapped around my cock." It thrust harder now, the pain of its claws mingling with the pleasure of being taken roughly from behind, driving Marcus further towards ecstasy.
With a loud growl, Predalien threw back its head and came, hilt-deep inside Marcus' ass, filling him to the brim with hot alien seed. The creature's body shook violently as it emptied itself into its prey, spurting again and again until there was nothing left but pleasure and exhaustion. At last, it collapsed atop Marcus, panting heavily against his neck, its cock still buried deep within him.
"There," the creature whispered, finally releasing him from its grip as it slid out of Marcus' ass with a wet pop. "That's done for now... but I will be back." It disappeared into the shadows once more, leaving Marcus to wake up alone in their shared bedroom.
