Work Text:

Dio didn't usually pursue victims from outside of his locality, but the cherry red haired beauty his gaze fell upon around the corner he stalked changed that sentiment entirely. Consequences that depended upon being caught mattered little to the vampire, who could easily outlive/escape most fickle human punishments.

Not that Dio ever got caught in his dealings, since he often sent subordinates to retrieve his meals who were often loners and hobos who no one cared about. The budding young man with violet eyes was too delicious however to simply have someone collect to devour him as a meal and be done. Oh no, Dio had fully intended on milking that desperate, reserved emptiness he carried in his body language.

Something about this particular boy had piqued his interest intensely. Aside from his unique coloration and alluring appearance, he had this vacant, insecure loneliness hidden just behind his violet eyes which absolutely BEGGED the immortal one to take swift advantage of it.

Dio gets what Dio wants, regardless of whatever insignificant setbacks may fall in his way. Alas, it seemed like the tarot had aligned for him as he gently tapped the other's shoulder and he easily turned around. Apparently he had never been taught to be cautious with strangers in strange places, because he absolutely left himself open to Dio's charisma. Naive, young hope housed in purple irises along with the loneliness. How perfect.

"And what's a young, handsome man like yourself doing prowling the streets of Cairo so late at night, all alone?" Dio questioned, wanting to goad him into spilling his insecurity to the blonde. His reply was disappointingly closed off, not allowing Dio much room, but there was just enough. "Just taking a peaceful quiet stroll on my vacation is all, I could say the same to you." The red headed stranger revealed little, but just enough for Dio to whittle open the wound.

"Oh that sounds pleasant, but why aren't you at your hotel with your companions? Or did you come alone?" Dio smoothly questioned, posing the statement as genuine curiosity. He could tell he struck the right nerve when he saw the other stiffen up. "No, they all went to bed before me, so I went out for some alone time. My name is Kakyoin Noriaki by the way." Kakyoin said, offering his hand.

An unexplainable chill rocked his body as he shook hands with the creature, feeling as though he were attracted to the strange man like some weird kind of magnetism. "Lovely meeting you, Kakyoin. So please do tell me, how long have you been in Cairo? How long are you intending to stay?

Dio planned to ask inane, seemingly harmless questions until he could slowly edge the younger into giving small details about his inner turmoil, details he could use to trap him in his snare. He soon delivered exponentially with minimal resistance, to which Dio was pleasantly surprised.

"Well truth be told sir, I didn't really expect to come, but my parents took me for my birthday. We plan on staying a whole month, but I actually haven't been minding the area too much so far other than staying with them." Jackpot. Dio now had an in. Kakyoin's family clearly didn't understand nor relate to him based on this small statement, and Dio hatched his plan. He would be Kakyoin's knight in shining armor, or so he would be made to believe.

If Dio could just win a sliver of his trust, which should be relatively easy with the other's inexperience, he would also win his loyalty. Forever. Dio had existed long enough now to be able to spot these types from far away. Lonely, misunderstood people who would seemingly do anything for even a pathetic crumb of affection. Dio wouldn't simply give Kakyoin crumbs, he would get the whole damn cake. He'd be so overwhelmed with gratitude that he'd have no choice but to obey. The sheer deviousness of the idea made warmth swarm between his hips.

Dio opted to spare a small harmless detail to make the teen feel at ease. "Oh, I'm afraid I didn't like my family much when I was your age either. They never understood me and I held immense distaste for their style of living. However I'm glad you enjoy my home despite that unpleasant story." He said flippantly, as if he hadn't engineered the statement to gain trust. He could slowly see the younger's defenses relaxing, and went in for the kill. "I'm likely not to retire to bed very soon myself, how about I show you some of the best local sights? This is my stomping ground and I know interesting things the tour guides always leave out."

The gullible young man fell for it hook, line and sinker. Kakyoin's eyes lit up just a bit, the prospect of potentially making a friend already driving him to say 'yes' to the strange man. "Well, I've nothing better to do, so lead the way if you don't mind." Kakyoin relented, smiling softly at the older man. "I'd be happy to." Dio smiled back complacently, beginning to take a walk down the empty street together.

—---
After some time of wandering the dusty streets of Cairo and looking upon the stars, Dio and Kakyoin happened upon the most exquisitely decorated Egyptian mansion. Kakyoin marveled at the piece of architecture while Dio plotted a way to lure him inside. "I see you've taken interest in my home, I would love to show you around it if you'd like." Normally it wouldn't even be this easy to sway someone who had just met him, but Kakyoin was just so damn naive and gullible. And Dio's charisma was more intoxicating than any.

 

The unsuspecting young man immediately nodded enthusiastically. "I've never seen such a nice house inside, I'd be glad to accompany you." He said softly, admiring the glow of Dio's golden eyes in the moonlight. Could Kakyoin call him his first friend? It almost felt too good to be true. Which, unbeknownst to him, it truly was. Dio unlatched one of the heavy wooden doors and held it for the younger, smoothly gesturing his other hand towards inside. "After you," He purred, rich as velvet. Kakyoin didn't know why the simple statement made something foreign gather deep in his stomach.

Something foreign that he only felt when sneaking a peek at his father's skin mags, or secretly sampling a view of other fit men during a beach day. He nodded, stepping inside. It was surprisingly dark to the redhead, used to bright incandescent lighting whereas all Dio had for lights were candles. The dim orange glow cast through the grand foyer made him feel like he was in a movie. A very romantic movie.

A heavy, cool hand landed on Kakyoin's shoulder. The aforementioned jumped stiffly, the vampire's presence raising his fight or flight response unknowingly. Something wasn't quite right. "Is everything to your liking? Was it as you expected?" Dio rumbles into his ear from behind, making gooseflesh rise on the redhead's arms. "It's better than I expected actually, I don't think I've ever encountered such an amount of opulence in my life." The young man stated, left almost breathless by the details put into Dio's home.

Ornate carvings decorated the ceiling edges, a stone staircase curved around the foyer with various mythical beasties and gargoyles etched into the side of the railing. An exquisite ruby colored rug, woven in flouncing filigree designs, likely Persian, was rolled from the doorway into the parlor area. It just stretched on and on, feeling as if it would swallow the senior student whole. "If you think this is opulent, just save your excitement for later, my friend." The century old vampire hinted, grinning with fangs fully bared. Kakyoin's pathetic human eyes couldn't even tell they were out.

 

Dio held a hand out to the eager tourist, this much he could see. He took it receptively, completely oblivious to the creature of the night's true intentions. "I'd love to see the rest, if this is just the beginning I'm sure it's worth the visit." Kakyoin innocently chimed, following the much bulkier man through a stone archway up the curved staircase. This brought them to yet another hallway that crooked to the left at the end.

Upon opening another heavy wooden and metal door, a fresh look of shock bloomed on the redhead's face. A gold, satin laden bed, full of silky, feather filled pillows, was adorned with 4 gilded posts featuring scrolling vinework up the posts. Thin red veils surrounded the bed, which in and of itself was ginormous and easily put a king bed to shame. It could fit 4 of Kakyoin as well as Dio comfortably and with plenty of wiggle room.

 

Raising a hand to his mouth, he could hardly do more than gasp sharply and look as if he were contemplating the reality of the situation. "I assure you, young one, it's all real and authentic, save the mattress of course. Ancient treasures like those you've never even heard of await you behind this door. Go on, you may enter." Dio purred, the other shuffling forward in almost a trance like state. He was in absolute shock at the sheer ornateness of the paintings on the wall, as well as the carvings that littered any furniture pieces.

 

"It's amazing, I've never seen anything like it before in my life. I don't even have anything to compare this to." Kakyoin guffawed, flinching when he felt the cool hand of the other slide along his lower back. Just a friendly gesture, he was sure. It's already more than he's been touched the entire week. Knowing this, the immortal man took advantage of the student's touch starvation. Giving a brief history of the items in his room, he moved the hand to his shoulder, squeezing and rubbing his thumb. Just this little taste would make the other fall completely open to more.

The high schooler was no stranger to the feeling of warmth pooling between his legs at the stranger's most innocuous touch, but had never felt such a rush from another person. Feeling himself clam up into a cold sweat, Kakyoin slowly extracted himself from the other's grip. "I-I'm sorry, this was fantastic but I need to um, be back before sunrise…" was his stuttered excuse, hoping his uniform jacket would hide the bulge that was slowly growing under it.

"Oh come now, it's hardly past midnight. The night is still young. Surely you don't tire of your new friend already?" Dio teased, boldly sliding his hand beneath the uniform jacket to feel his back through his thin dress shirt. This wracked a shiver from the Japanese man, the press of Dio's palm and tips of his claws so much more insistent as he began to pull him close. "Oh, no, absolutely not. I'm honored you would have me." Kakyoin quickly recovered. Surely friends didn't feel each other up like this, but how would he even know? He'd never had one. He shuddered as a clawed finger teased along the edge of his jaw.

"I like that answer." Dio sneered, quickly locking his lips with the startled redhead with a shocked "Mmph!". Too busy already frozen from the surprise kiss, the senior stayed limp as Dio picked him up and wrapped his lithe legs around his waist. He had never so much as held hands let alone been French kissed. Carrying him to the bed, Dio nipped at the redhead's lips with his fangs and groaned at the salty tang of blood that trickled between their mouths as they slid together.

Immediately Kakyoin's thoughts became a warzone as he whined into the borderline feral kiss. On one hand, he was feeling like he didn't want the unfamiliar touching to continue, which the other seemed fully intent on by the way he nursed the injured lip. On the other, he had never even had a friend, and had no idea of how relationships worked, and he never had a chance to explore anything his peers did. He didn't have to tell a soul what happened when he took a walk on his vacation in Cairo while his parents snored peacefully. This was his one chance to experiment freely and there were no consequences.

Saying 'fuck it' and opting to see where the night was going, Kakyoin decided he didn't have anything to lose and gave up the ghost. Leaning into the slick gnashing of lips and teeth and tongue, he moaned breathlessly as Dio's abdominal muscles rippled against the front of his pants. Suddenly he was dropped, landing in the pleasant, slippery ocean of satin bedclothes. Kakyoin didn't have to wait much longer before Dio was engulfing him under his body, laying between willowy thighs and smothering the other's lips with his own.

Pulling back, the only thing Dio paused to do was rid them of the unnecessary clothing. Dio practically tore the clothes off of Kakyoin. He threw the green jacket, slacks, shoes, and white button up in a corner, leaving the other in nothing but his red briefs. He took a moment to marvel at the newly exposed body, reaching down to leisurely rub at Kakyoin's dusty brown nipples. This resulted in a dry gasp tearing from his throat, a small bead of precum marking a dark spot on his underwear. "Haven't you ever thought of touching here? So responsive…" Dio hissed, leaning down to drag his fangs down Kakyoin's chest, leaving a trail of 4 linear, almost-bleeding welts to the right nub.

Kakyoin whimpered and shivered as the burning sensation gave way to a supple pair of lips and a warm tongue. The sensation gathered in a hot pit behind his belly button, causing him to squirm in abandon. Dio allowed a fang to catch on the abused nipple, bringing a drop of blood to the tip. Instantly, he sucked it into his mouth harshly, wanting to draw more of the sweet, salty life force he had come to need. "Ahhh-! Hurts-! Why does it feel so good–!?" The redhead ground out, his cock feeling absolutely smothered by the undies Dio refused to remove.

"Shh, my friend, don't question it, just accept." Dio rumbles into Kakyoin's ear, the sound tearing through him straight to his cock. Continuing to nurse small bits of blood from his chest, Dio moved a hand to rest over Kakyoin's straining erection. Rubbing gently, he basked in the fucked-out moan he got in return. Adjusting so his grip was more firm, he slid his working jaw to the other side of Kakyoin's chest.

Taking the other nipple between his emerald painted lips, he suckled it gently and teased his counterpart. When he wasn't expecting, Dio bit down around the bud, hard. "H-haahh!!" A quivering whine strangled itself out of Kakyoin's throat, red hot pain blooming on that side of his chest and further fueling the inferno in his veins. His long, delicate cock jumped in his briefs and dripped as Dio moaned and lapped the continually oozing incisions he had made.

Dio reared back after allowing the wounds to heal closed. "You taste simply divine." He hissed, inhumanly long tongue snaking out to press and search for the pulse on Kakyoin's neck. "What- What even are you?" He whimpered, erection having not flagged an ounce. The situation was so dangerous, yet the allure possessed by the other held him fast in his place. "Why, dear friend, long ago certain… circumstances… rendered me an immortal creature of the night. I have been positively starving as of late, and once I smelled your sweetness I had to have you."

The younger could only respond with an aprehensive whine, trembling like a leaf as Dio finally elected to rid Kakyoin of the damp undergarments that had annoyed him so. Kakyoin considered the potential efficacy of trying to convince the other to spare his life. Dio could smell the fear radiating off of him, it made him strain in his pants. "Don't fret, sweet thing, I have no reason to dispose of you. I simply acknowledge my… intense thirst."

Despite the relief that coursed through Kakyoin at that statement, his fear didn't dissipate entirely. Now bared entirely to the century old vampire, he lay waiting for the carefully calculated next move of the other. Dio flung the moistened cotton into the darkness, drinking in the soft candlelight twinkling in Kakyoin's wide, fearful eyes. Trailing his lips down the slender neck presented to him, Dio sucked and nipped red marks down its entire length and settled his mouth over the tantalizingly thrumming location of his jugular vein.

Dio could feel the sharp jump in Kakyoin's heart rate beneath his painted smirk. He could feel the way Kakyoin's chest tightened to maintain some semblance of control over his breathing, trying not to reveal the dread that made him twitch and jump and drip against his own abdomen. After a moment of massaging the spot with his tongue, he slipped his clawed but incredibly soft hand over Kakyoin's arousal. A soft keen caught in his throat at the first touch he'd ever felt there other than his own, but it quickly became a sobbing shout as the puncture of long fangs deep into his flesh catapulted him over the edge of an unexpected orgasm.

Dio pulled and tugged the teen through his first orgasm of the night making no mockery of his premature release, gulping down mouthfuls of blood sweetened by the endorphins from his climax. Just knowing he had caused such a palpable effect made him twitch in his black leotard and groan darkly. Kakyoin whimpered as Dio waited until he was completely spent before removing his hand, then his teeth.

Dio drank his fill, pulling back before the younger began to get light-headed. He watched as Kakyoin lay there, eyes misty with the remnants of a not long gone release. However, Dio still had not had his end of the ordeal fulfilled, which was very much a problem. "I'm not nearly finished with you, we have a whole night to get to know each other and I plan to make use of each minute." He gently whispered, turning the tourist over and lifting his hips into the air.

 

Kakyoin inhaled sharply, fully expecting the other's well endowed length to be right behind him. On his inspection, the elder was procuring a jarred substance from the nearby night table. He opted to look ahead and just feel. Slicked fingers with pointed nails ran over Kakyoin's hole, wriggling against it gently before sliding in. This wracked a gasp from him, shuddering at the feeling of something that could potentially be so painful had Dio not known how to move with his nails.

Dragging the pad of his finger along the front wall of his insides, Dio smirks devilishly when Kakyoin's back arches and a reedy whimper fills the room. He found the spot he would use to break the redhead's resolve. Locating the small bump with his first finger, he slides in a second and begins working them in and out of Kakyoin. On every pass in and out, Dio crooked his fingers just so to hit his prostate. Kakyoin's erection swung helplessly between his legs, already once again fully hard and drizzling precum everywhere as he whined desperately.

Dio drank up all of the younger man's inexperienced sounds, ecstatic in the most evil way that he had been the very first to wring them out of him. Opting to taunt him with a few last thrusts, Dio unceremoniously yanks out his fingers from Kakyoin. Grasping around for the jar he brought, the vampire used it once again to coat his thick endowment in lubrication. 2 fingers probably wasn't enough, but he could tell Kakyoin was one to enjoy the burn.

Dio flipped the younger onto his back, dragging him down the bed by his hips until the blunt end of his cock rested between Kakyoin's angular little ass cheeks. Folding his legs toward his stomach, Dio pressed in gently but insistently, not stopping until he was fully hilted. This drew a continuous stream of whines, moans, and gasps from Kakyoin, grappling between the immense stretch and the foreign pressure against something that made his toes curl.

Dio smirked down at him, his own breathing increased because of how tight Kakyoin was around him. If he ran a hand over the redhead's flat stomach, he swore he could feel the bump of his head poking through. Groaning darkly, he withdrew slowly before plunging himself all the way back in and starting a harsh rhythm. "Fuck-! It's too much-!" Kakyoin gasped, writhing under the overwhelming creature. The still very stiff cock smearing his stomach completely betrayed his struggle.

"Oh you poor thing, if you squeeze any tighter you might break it off inside you." Dio chuckled, increasing the speed of his movements until the younger man's entire body bounced with the force of his thrusts. Airy moans and sobs left Kakyoin's throat with more force as the increase in intensity never left his prostate untouched. The most he had experimented with was his fingers and Hierophant's tentacles, and Dio was much fatter than either of those. He felt completely open, vulnerable to whatever Dio wanted to see, touch, taste, and smell. It made Kakyoin's head spin with disorientation.

Kakyoin could feel the way his ass clung to Dio's shaft every time he withdrew, the way their hips impacted each other with almost bruising force. He moaned gutturally when the older shifted to get a mouth around his injured nipple, resulting in Dio's already deep thrusts somehow becoming even deeper. Instead of biting harshly like before, he gently slithered his long tongue around the sore nub in time with his almost animalistic rocking. Kakyoin felt as if Dio were physically wringing the pleasure from him, already feeling another orgasm building even with no touching his neglected member.

Dio pulled himself out tortuously slowly, and moved them both so that Kakyoin kneeled on top of Dio's legs facing him while he rested against the headboard of the Olympic sized bed. He grabbed a handful of Kakyoin's tight but round ass, guiding him back down onto his cock with an embarrassing 'schlep'. "Shit! I-it feels different-!" Kakyoin cried, thighs quivering as he leaned into Dio's chest.

"Mmm, yes… Show me how much you want me!" Dio growled, using his vampiric strength to force the lighter man up and down on his dick. Kakyoin began to undulate his body with the movements, struggling to keep his legs from shaking with the swelling and falling pleasure in his loins. Grasping onto Dio's shoulders for support, he began to bounce himself clumsily up and down, his stray curl swirling in the air with his motion.

The new positioning made Dio's cock stab him almost directly in the prostate, resulting in some flying drool and a hoarse shout. Kakyoin's moans began to shudder from the intensity of their coupling, his weeping, turgid dick bouncing around with the frenetic rolling of his hips. He was so far gone, any worries about his hotel room or his family completely discarded as the venom in his veins compelled him to do unspeakable things.

Dio began to move his own hips up when Kakyoin brought himself down, the increased pressure bringing a punched out whimper. A few more deep, frenzied thrusts and that was it for the younger man. With a hushed wail, he erupted between them, cum bubbling down his shaft as he pulsated around Dio. He whined softly, leaning into the vampire and embracing him as he rocked 4 more times to ease his afterglow.

Dio slammed up into him a few more times, completely disregarding the oversensitivity Kakyoin was likely experiencing to chase his own high. With a growling moan, he stilled, planting himself as deep as possible to release his seed. Kakyoin panted harshly as he felt the warm liquid seep into him, completely spent from the most mind blowing orgasm he had ever had.

Dio removed himself quickly but tenderly, rolling the young man onto his side in front of him, and settling in behind. Kakyoin felt the wall of warmth behind him and decided, his parents be damned. Soft snores came from him soon as he passed out, wrapped under one of Dio's large arms.

His parents never saw him again.

Notes:

"Have you ever been in love
With someone you hardly knew
Whereas every time you closed your eyes,
You saw this person come alive
It kept you wide awake at night
You felt like you were burning up
In pain, you want to scream
Then you passed out in a dream
Just once or twice is good for your soul
Just once or twice is good for your soul
If you don't stop, you'll lose control
Just once or twice is good for your soul"
