A/N: I want to thank everyone so much for the positive feedback! Happy to know people are enjoying reading about Dio/Jonathan as much as I am enjoying writing it, haha. This is where the story really starts veering off, but I promise I'm not doing anything crazy and drastic yet.

It's rated M for a reason. Please keep this in mind while you're reading, thank you.

His and His Alone

-Chapter 2-

Things were not that much different between them. If anything, Dio found himself being a bit more kind to Jonathan. However, this didn't stop him from throwing a few rocks in the Joestar's path through verbal mockings and physical jeers and jests. Still, though, Dio was indeed becoming more infatuated with this man.

Their walk to classes in the mornings were filled with a more pleasant air, not one laced with distrust. And this, in it's own right, caused Dio to smile inwardly to himself. Jonathan was trusting, far too trusting. One night they had spent together, and the large man was a dopey mess. How very like him to be such a hopeless romantic.

Shared glances were becoming more common. Glances that were previously wary, almost distrusting, were now filled with admiration and sincerity. On a few occasions, Jojo had even intertwined his fingers with Dio carefully, making sure no one was around, and then taking the hand fully in his own as they walked down the dirt roads, shy little smiles beaming on Jonathan's end.

Oh yes, it caused Dio great joy to know what he had done, what he was able to accomplish. Jonathan was too easy and, by far, too trusting. All his life, he had gone out of his way to torture the man, and now he suddenly had a change of heart? Oh no, life wasn't that simple.

To Jonathan Joestar, though, it apparently was. It was that easy to forget all the indiscretions someone had caused to your person. Dio knew this was just the darker haired man's personality, though. He supposed he would really have to thank their father for that.

"I'll see you later, then!" Jonathan's voice interrupted Dio's thoughts, causing the lighter haired man to become more in-tune to their surroundings. When they had arrived at school, Dio wasn't sure. But keeping his demeanor in tact, the smaller man turned his full attention to Jojo, smile wide, and purred, "Yes, see you later, Jonathan."

The younger Joestar smiled widely as well and walked down a hallway, giving Dio a tiny wave as he went. Dio, for his part, continued to smile, not breaking his stare with Jonathan, even after the man had turned around and down another hallway into a room.

Straightening his uniform, Dio turned sharply on a heel and began making his way to his own room.

-x-o-x-

Commonly, the two men wouldn't wait for each to eat, to leave, to return home. Truthfully, their schedules didn't coincide very well anyway, so whenever they saw each, was when they saw each other. Unless they had practice or a game, of course.

Today wasn't any different. Except today, Dio was curious, and decided to spy on Jonathan for a bit. He was smarter than his peers by far and wasn't worried about their stupidity ruining his grades or anything of the sort. Plus, he didn't usually skip out on his studies, but no one ever said anything if he did.

Packing up his materials, Dio exited the room silently, making his way towards the room Jojo was in from the outside in order to make himself less suspicious. And if he waltzed right into the man's classroom, disrupting everything with his foreign presence, then he wouldn't be very good at spying.

Peeking into one window, his eyes scanned the inner workings until they fell on his prime adjective. Jonathan was scribbling something quickly into a notebook, flipping through some pages, eyes focused in pure concentration on whatever subject he was currently studying.

Dio smirked. Sure, it was Jonathan's impressive body which had, presently, been capturing his attention over anything else, but it was sort of cute in a way ... the way Jojo put so much effort into learning and bettering himself and becoming something of worth. When, in reality, Dio controlled everything: What he was, what he would be.

He hadn't been standing out there very long before Jonathan stood up after packing away his things and made his way for the exit as well.

But instead of going to meet him, the lighter haired man thought it would be more exciting to follow the man. He would have time to talk to Jonathan at home. For now, he wanted to merely watch from a distance. Something he was very accustomed to doing as of late.

Jonathan took the same path home in silence, every now and then whistling or happily greeting someone as he went. Boring, dull, very much Jojo, Dio mused.

"Jojo!"

The voice was high pitched and foreign. Dio slipped silently behind a tree when he saw a figure approach, latching onto Jonathan's arm when it was close enough.

"Oh! Erina, hello!"

Dio's heart paused when he heard the name. Anger flared up immediately within him, hair starting to stand on end, pupils dilating as his pulse quickened. His teeth clenched together tightly, a small hiss forcing it's way out between them.

"How was your day?" Erina's voice was very sweet, extremely and sincerely happy. It made Dio sick.

"It was pretty good," Jonathan's voice replied back just as happily, causing Dio to peer angrily out from behind the tree, "Found out a lot of interesting information today."

Erina's arms were curled around one of Jonathan's as she pressed herself close and laid her head on him as they walked.

Dio's teeth grated together, hands curled tightly into fists. He did not like this woman, not in the slightest. The very sight of her pissed him off. She had been the only person who had given Jonathan some happiness when they were younger, the only person who had enraged the man enough for him to strike Dio. Truly, it had taught the smaller man some boundaries when it came to Jonathan, let him know what buttons he could and couldn't press.

But Erina had seemed to vanish after that, or so Dio had thought. He hadn't heard Jonathan mention her either, so he just assumed that she was out of their life for good.

And yet here she was, and Jojo didn't act surprised to see her, which just increased his anger. He was keeping things from him, that Jonathan. But even in realizing all these things, Dio was still angry to the point of being enraged. His heart pounded harder in his chest, knuckles turning white from the tightness of his fist.

He was jealous.

He couldn't believe it, didn't want to be believe it, but he was, overall, jealous that Erina was hanging on Jojo, treating him kindly, receiving his affections.

Dio wanted to kill her. Slowly.

"I'll see you tomorrow then, Jonathan!" Erina waved at the large man as she took off down a different path, smile beaming as she went.

The young Joestar waved back in reply, smile mirroring hers.

Dio slipped undetected from his place behind the tree, quietly moving in shaded areas towards his location, anger still etched in his face. But he wasn't following Jojo.

-x-o-x-

Erina walked home quietly, carrying her produce and other perishables in her basket and swinging it a little as she walked. She hummed to herself, lost in her own thoughts. And it was because of this, that she didn't even suspect that someone was following her.

Until a hand shot out and grabbed her arm viciously, pulling her into an alley way, twirling her body around, and, finally, slamming it into a wall. Her eyes grew wide instantly when she recognized Dio, face twisted in an angry sneer. His body leaned over hers, casting a dark shadow, only adding to the initial dark and dinginess of the alley.

She whimpered, trying hard not to make a noise as she stared, horrified, at the man holding her wrists tightly. His fingers dug into her skin, threatening to break it. Pushing them into the building's foundation, bricks scraping roughly against the backs of her hands. Dio's breath was slightly ragged as he, too, glared deeply into the woman's eyes, the red of his iris's seeming to shine angrily.

And, what after seemed like an eternity, Dio's lips curled into a tight smile, breathing out a deep, "Why, hello, Erina."

"D-dio," the woman breathed out, scared that by even saying his name, the man would do something worse.

To her surprise, he only continued to hold her wrists tightly, not making any sort of move to hurt her further. But his random breaks of silence were unnerving, fraying to her sensibilities. And she dared not question the man further, only continue to stare into those cold, hateful eyes.

"Hanging around with Jonathan, I see," the lighter haired man finally spoke again, cruel smile still in place, "That's not a very good idea, is it?"

She didn't respond to his question. Erina simply continued to stare at the man hovering over her, trying everything in her power not to scream out or cry. If she did, the small woman had a passing thought that Dio would kill her. Not throw her to ground or kick her, but very surely kill her.

"Is it?!" Dio hissed, applying more force to the wrists, wrenching her against the wall more tighter still.

Erina didn't attempt to dull the quick scream that ripped from her very core. She could feel the bricks digging into her knuckles, causing blood to drip down her hands and around her wrists lightly.

"I-I don't ... ah! ... I don't understand why you're doing this!" was the reply Erina chose to give instead of an answer.

Surprisingly, Dio released her at this, causing the woman to slid to the ground. She didn't stop the tears from escaping now, putting a hand up to her face to attempt to, at least, shield them from the man.

"Don't come near Jonathan. Don't touch him, don't look at him," Dio began, voice no longer masked with feigned kindness, "and don't even think about him. Are we clear, bitch?"

Erina removed her hand from her face, breath catching her throat when she realized Dio was right in front of her, crouching down to be at her eye level. But she nodded vigorously, her body betraying her with muffled sobs and shakes.

And then the fake smile returned.

Dio reached out a hand and wiped a tear harshly from her eye, "That's a good girl, Erina." The name was hissed, barely spoken. And then he was gone. Golden hair shining as he stepped back out into the sunlight and out of sight.

The young woman let her tears run freely when she was positive her aggressor would not return. Something was wrong with that man, very wrong. She had been assaulted by Dio before, but he was wasn't as large back then and had done far less physical damage. But every time she had been around Jonathan, had shown interest in Jonathan ... that's when Dio was there.

It wasn't right. The whole situation ... it was scary.

"I ... I have to tell Jonathan."

-x-o-x-

He made quite clear that he wasn't in a good mood. Slamming the manor's doors open, stomping up the stairs and into his room, not speaking to anyone, even Jonathan.

But when questioned about his brother's actions, Jojo could only shrug his shoulders. Whatever had happened between this morning and now, the darker haired man wasn't sure. And Dio rarely became so angry, so it was obviously something extremely problematic.

Knocking on the door to his adoptive brother's bedroom, Jonathan gave out a slightly worried sounding, "Dio, are you okay?"

There was no reply in return, however. Letting out a sigh, Jonathan gave a quick nod before turning the handle and opening the door slowly, hinges squeaking louder than he remembered as it went.

Dio was sitting in a chair in the corner of his room by his desk, focus on a book he seemed to be reading. The anger from earlier when he had entered the mansion still evident.

Jonathan took a few steps into the room, pausing just beside Dio's bed. He didn't want to get too close, lest the smaller man take out his anger on him.

"Dio," Jojo tried once more, "Are you okay? What happened?"

The lighter haired man flipped a page in his book, voice low as he spoke, "Why were you with Erina today?"

The question took Jonathan by surprise. How had Dio known such a thing? "W-well ... um, I-"

The book slammed closed suddenly, causing Jonathan to go further on alert, body becoming tense, the remainder of his sentence becoming stuck in his throat.

"Jonathan," Dio pressed on, not really caring for his adoptive brothers explanation anyway, "I don't like her. I don't like the way she looks at you."

Setting the book down, the smaller man walked over to Jonathan as he spoke, finally coming to rest before the younger Joestar, hands curling dangerously in the collar of his shirt, "And I don't like the way she holds onto you."

A kiss on the lips, teeth scrapping the bottom one possessively as Dio's left Jonathan's to hover closely, breath floating heavily between them, "She does not know you're mine. And that's a problem."

Jonathan's body shook despite himself, breath becoming shallow as Dio's fingers ran down his arms lightly, "She's ... hn, she's a friend of mine, Dio. Maybe if you talked to her a bit you'd see she's not so bad."

The roaming fingers stopped and gripped tightly onto wrists yet again. However, these ones were indeed bigger, more powerful. And Dio's face changed to utter rage once again, eyes flickering with malice as he spoke, "I don't want to talk to her, I don't want her to talk to you. I don't want her thinking about you late at night while she pretends to be asleep, touching herself, and moaning your name like a whore."

Hand retracted from his brother's wrists and gripped tightly onto his face instead, jaw clenched beneath his fingers, "You're mine and mine alone, Jonathan."

The larger man said nothing as his eyes went wide, redness beginning to creep along his cheeks. Dio yanked his head close to his and kissed him deeply once again, eyes focused on Jojo as the darker haired man squeezed his own shut in bliss.

And after only a few moments, the kiss was over and Dio was heading towards the door, leaving Jonathan to wonder, question, mull over his own thoughts. A silence lingered between them until Dio reached the exit and turned his head slightly, enough to catch his brother in his line of sight, "Mine."

-x-o-x-

After leaving the man in his bedroom earlier, there was no question that Dio was digging deeper into Jonathan's emotions. Last time, when he had mistreated Erina's honor, he was struck quite violently. This time, Jojo had no words, his facial expression didn't turn to that of anger or hatred.

And to their father's surprise, the man had even declined dinner. For what reason, neither Dio or George Joestar could explain. Dio did have a few assumptions, though. After leaving the lighter haired man's room, Jonathan ventured quickly into his.

While he didn't hide in the closet this time to spy on his brother's actions, Dio had given him a lot to think on. He was his. Those few simple words rendered the man speechless. But what was nice about Jonathan was that he was very influenced by words, by actions. Combining the two had only solidified Dio's message.

And not one protest to see Erina, to talk to Erina. Oh yes, Dio was good.

And even after dinner was long since cleaned up, after Dio had partaken in studying for a bit, Jonathan didn't leave his room. Odd, perhaps. But slipping into bed that night, the lighter haired man didn't give it much thought as he pulled the sheets over his muscular frame.

He had been giving Jonathan a lot to think about lately.

-x-o-x-

It hadn't even been a week since the last time they were together in Jonathan's bed. Dio was surprised at his brother's eagerness when he came to him in his own bed late that night. The house was completely silent, everyone was sleeping soundly in their own rooms, unaware of what the two young men were up to.

He heard the click of his door being opened, heard the footsteps as they moved quietly to his bed, heard the faint breathing, trying hard to be silent. Dio turned in his bed to face the intruder, smile forming almost instantaneously when he saw Jonathan standing beside him, eyes turned down towards the floor, cheeks holding a slight blush, lips moving like he wanted to say something but couldn't find the words.

So Dio found them for him.

"Oh, Jonathan, are you lonely?" he whispered sharply, disturbing the stillness of the manor. Jonathan's eyes never left the floor as he nodded slightly, tilting his face down in hopes his hair would shield him from his brother's gaze.

"No need to be so shy," Dio purred, standing from his bed and immediately running his hands up and down the muscular body before him. Goosebumps, shudders of pleasure immediately arouse due to the contact, causing the lighter haired man to chuckle.

Dio slipped his hands under the nightshirt, running his fingers over the already hard nipples. One hand dropping to Jonathan's crotch and brushing over it, feeling the already hardening erection.

The laugh escaped his lips loudly, "Oh, Jojo, you get hard just thinking about me, don't you?" Hands continuing to move and explore, causing the larger man to gasp and whimper quietly, the darker haired man's eye keeping their gaze firmly on the floor, now almost squeezed shut.

A hand shot quickly up from the chest and gripped Jonathan's chin, turning his head roughly to face Dio's. Jojo's eyes widen in surprise, now staring completely into his brother's deep, red eyes, his perfect teeth gleaming in the moonlight.

"Jonathan," Dio hissed, moving his face closer to the larger man's, "You came to me. And I expect you to tell me just what you want."

Each word was emphasized with a kiss, a bite, a pinch from Dio, sending Jonathan's body into a world of built up pleasure, erection pressed tightly against the palm of Dio's hand as he rubbed him.

"I, ah! ... I m-missed you, is all," Jonathan stammered out as coherently as he could, gasps now becoming louder the longer Dio worked on his body.

"Missed me, now isn't that sweet," Dio's voice was mocking sincerity, "Was it you who missed me or ... was it your cock?"

The last word was emphasized with a tight squeeze to Jonathan's dick, dripping in anticipation. His moan was too much to contain and he laid his head in the crook of Dio's neck, fingers gripping wildly onto Dio's own pajamas, pulling the two closer together.

"O-of course ... I, ah, mean me."

"Oh, of course," Dio laughed once more, running his lips over the lobe of Jonathan's ear. He didn't care if Jonathan missed him, didn't care if his prick was the only motivation. The thing that was getting Dio going was the knowledge that Jojo was so eager and ready to give his body to him. It was exhilarating, to hold this man in his arms, to make him scream and squirm. Obvious, that his words from earlier were taking hold of his dear brother.

Fingers ran their way down a cheek, over a chin, and finally, they gripped their brother's neck in it's entirety. Jonathan choked, breath hitching in his throat as he reached a hand up to grab Dio's wrist. But it merely stayed, didn't try to pull the offending hand away.

"Hmm," the lighter haired man mused, pushing the Joestar down onto the bed, "Who would've pegged you for a masochist?"

Jonathan merely gasped as Dio's fingers curled harder around his throat. But Dio could feel everything: the heartbeat, the strangled cried, the trapped moans. And the way Jonathan's lips were parted, tongue lolling, only added to his eyes, those deep, blue eyes which were glazing over, rolling in their skull.

And there were flickers of Erina that smeared across Dio's vision. A vision of him choking Erina as well, watching as the life flickered out of her eyes. Until he heard Jonathan's voice, heard the man's gurgling, and he focused on that face. The face of the man who was too trusting.

Dio held Jonathan's life in his hands. Quite literally. Jojo trusted him enough to let Dio control his slip between consciousness and reality. And the man was getting off on this?

It only made Dio harder.

When the pants had been removed, neither man was sure. But the smaller man didn't stop to contemplate this as he pushed his arousal roughly into Jonathan's ass, feeling the man tighten around him in immediate pleasure.

This time, a gasp did escape the man's lips and a moan followed soon after. Dio's fingers rubbed the neck, feeling the tendons as his body thrust forward over and over again, growing ever harder by the way Jojo's lips mouthed his name. And no sooner had Dio released the man's neck did his brother come, a strangled moan, from the deepest reaches of his throat and belly, poured forward, filling the somewhat quiet room with noise and the dirtiest kind of lust.

Jonathan's hips bucked down onto Dio's penis, causing the man to follow and come not much later, once again, filling him with everything he could. Dio, for his own part, couldn't help in pushing out a "Jojo!" that was so deep and laced with passion, surprising even his own ears when he said it.

But it mattered not. Because when he saw Jonathan lying beneath him, used and worked, mouth still parted as breath escaped it raggedly, marks from his fingers burning red on the man's neck, eyes transfixed completely on his, it was bliss.

"Oh Jonathan, you are a pretty little thing," Dio commented out of breath, reaching his head down to cover the other man's lips with his own.

"D-dio, ah," Jonathan gasped, enjoying his brother's tongue running over his lips and through his mouth, "I ... love you."

The lighter haired man was caught off guard. Stopping the kiss, he looked directly into Jojo's eyes for the signs of a joke or, perhaps, he had misheard him. But those eyes, those damn, loveable blue eyes ... they stared at him with conviction, with complete seriousness.

Dio leered at the man before pulling him into a hug, fingers now curling into the large, muscled back and into the messy, dark hair. Staring at the star shaped birthmark, Dio almost choked out a laugh before whispering back, "I love you too, Jojo."

And how he did so love his brother. His lover. His Jonathan Joestar.

Chapter 2

End

A/N: Okay, I really do like Erina, I'm just trying to make unnecessarily mean conflict, haha. Reviews are always very appreciated, and thanks for reading!
