Work Text:
Work was everything to Jotaro Kujo. It was one of the perks of doing what you loved, so it shouldn't have been a surprise that he let something like this slip past him while he was focused on his thesis.
In his defense, it wasn't anything too out of the ordinary: feeling more irritable, restless and even slightly sick was the usual, so he just assumed it was due to his own neglect and went on with his investigation of Morioh’s starfishes, as he'd been getting closer and closer to finishing the first draft.
What he should have noticed, though, was the sudden urge to have sex with any person he came in contact with... which hadn't been much, but since he frequented the beach in summer, it was inevitable that he'd encounter people there. Jotaro wasn't much of an extrovert and neither a sexually active alpha, so this amount of desire should have made alarms go off in his head.
It reached its boiling point when he found himself fisting the sheets while he breathed heavily. His clothed cock painfully hard as it ground against the bed shamefully.
“What am I, a teenager?” The man's face burnt with embarrassment. “Damn it…”
A pair of hands touched his hips, almost making him scream bloody murder when he turned to look at the bearer of them.
“Star Platinum?" He asked, but didn't get an answer as his Stand moved him around, and of course Jotaro let it, because even though he hated touching other people, Star Platinum wasn't like them at all. It was gentle and would never do something Jotaro wouldn't like. It was safe.
Now on his back, Jotaro could see Star Platinum hovering over him, though it looked tense, its face was scrunched up and flushed a darker purple. Looking down, Jotaro found something he expected, but didn't at the same time.
Star was rock hard. His hips were visibly shaking with the effort to not grind against Jotaro, who couldn't tear his eyes off of the monster cock his Stand had managed to hide from him. He didn't even know Stands had any kind of organs, much less reproductive ones.
“Fuck," the man said, eyes widening as he sat up on his elbows. "What the fuck- what the fuck?” he spluttered, now extremely confused at the new discovery.
“Ora-" Star grunted, his teeth clenched hard as he fought to stay still.
Without any restraint, Jotaro's hand traveled down to Star Platinum's cock, watching how he could barely wrap his fingers around it. Immediately, his Stand thrust his hips forward, fucking Jotaro's closed fist with carnal urgency. The man felt his own hand all over his length and choked back a moan, the transmitted sensations becoming too much in his sensitive state.
"It's- ahh… my fault, sorry," Jotaro grunted, but his hand didn't stop its movement.
Star Platinum was practically growling on Jotaro's ear, which only made him go faster, with the slick sound of his hand sliding on Star’s cock fueling his arousal.
Then, Jotaro found himself pinned down by his shoulders, and he watched his Stand's chest heave, his gloved hands tightening on the thin fabric of his shirt. Star Platinum didn't move though, he just stared at his Master through half lidded eyes. The tension was cut short when a shiver ran down Star Platinum's spine and he pressed his head against the crook of Jotaro's neck, taking the man by surprise as he started to rub himself on the other.
“Star-” Jotaro started, but found he didn't mind it that much. He was in need of touch, after all. “Wha- what…”
Whatever question he was going to ask was answered when Star Platinum hooked his hand under Jotaro's knee and pressed it against the man's chest.
“Oh,” Jotaro breathed, realization dawning on him. "You're an alfa too, aren't you?"
Star Platinum nodded and pressed his face harder on the other's neck, making Jotaro gasp.
“But… I'm not- not an omega-” Jotaro tried to say, but was pleasantly surprised to feel Star's lips clashing against his own with a delicious, burning need that consumed the last of his reason.
Wrapping his arms around its shoulders, Jotaro pressed his Stand closer until they were chest to chest, their mouths moving together in a dizzying rhythm.
“Please," Jotaro or Star Platinum begged, the user was too fixated on the amazing taste of the other's mouth to care. "Please please please please-"
Already knowing what he wanted, Star Platinum ventured lower and lower on his body, leaving wet kisses and the occasional love bite all the way down to his thighs with something akin to devotion. It gently bit the skin of his inner thighs before noticing his hardened member and unceremoniously taking its entire length into its mouth.
Jotaro fisted the sheets and covered his mouth before any embarrassing sound managed to escape. Star Platinum lacked any technique, but it was still so good that he couldn't help the mindless praise he spewed to the Stand, calling it the sweetest things his horny brain could come up with as it licked and swallowed him down like he was nothing.
While Star Platinum drowned Jotaro in pleasure, it sneaked one digit between his legs and slowly pushed inside of his unprepped ass, tearing a gasp from the man, who squirmed and clenched around it while frantically trying to get away.
“A-aaah! W-wait!~" he cried before an unexpected, high-pitched noise slipped past his trembling lips. Star Platinum, having found his prostate in its poor attempt at loosening him up, immediately began attacking it by rubbing the nub incessantly until Jotaro was an overstimulated wreck, so much that a burning hot substance shot down its throat, and it felt a tingling sensation on its legs as its cock twitched hungrily where they ground against the sheets.
"S-stop.. stop it, stop..” Jotaro muttered breathlessly, his hand that'd been previously silencing him going up to its head to grab a handful of black, silky hair to try and pry it away from his still half-hard cock.
Star Platinum, much to his gratitude, let the member fall with a wet plop on Jotaro's belly before just… vanishing. Jotaro thought that he'd scared it off, which made guilt crawl into his mind alongside post-nut clarity, mixing into an identifiable ball of shame and regret and—
The familiar face of his Stand came back into view, generously sized bottle of lube in hand, easing the pressure on Jotaro's chest as soon as it appeared, though a single thread of worry lingered in his hazy mind.
“You… do you… um- are you okay with.. this?” Jotaro asked, hesitantly signaling himself. “Do you want me?” he murmured, not intending for it to hear, though it clearly did anyways, as it leaned down to press a kiss to his head in affirmation.
Going back to the matter at hand, it squeezed the bottle’s contents onto his fingers and immediately pressed two of them to Jotaro's rim, making him yelp with surprise at how cold they were. Once inside, he groaned at the feeling of those thick digits stretching him in a way nothing ever did before. He'd only seen this type of thing in magazines, and yet he was never brave enough to try it on his own… but then there was Star, who, without any experience, had managed to tear one orgasm from him already.
When it found that spot again, Jotaro warned it in his mind to avoid grinding it so hard to avoid bruising it and pushing him over the edge again, and, as always, it obeyed with no complaints.
Once they moved on to the third finger, Jotaro felt like he was losing his mind.
He grunted. “I should be ready by now!” The man complained, but this time, Star didn't listen, as it continued to open him up with meticulous strokes and almost uncanny dedication considering their situation. Jotaro had to endure another four entire minutes until Star almost had his entire fist inside while it held a quick, thrusting rhythm. Only then did his Stand pull out and, finally, reach out for the bottle.
It squeezed an important amount on his ass, making him shiver, before it poured even more onto its cock.
“It's too much lube” Jotaro thought when Star Platinum stroked its enormous length with copious amounts of lubricant.
He held his breath as Star Platinum grabbed his thighs and gently lifted his hips, its tip pressed against his rim until it started pushing in as slow as it could manage.
"N-not enough- fuck!” Jotaro choked as he took in the sheer size of Star, who looked down at him with an overwhelming need as it kept pushing and pushing until its hips met his pelvis, leaving the man heaving with tears burning in his eyes.
“It's like I'm fucking myself-" he thought deliriously as his walls tightened around Star’s cock. “I… I can't take it!”
His thoughts were interrupted by Star Platinum kissing away his tears before capturing his lips in a searing embrace that washed away the pain for a moment, providing enough comfort to allow Jotaro to give the slightest nod for it to go on.
“Be gentle…" Jotaro said through gritted teeth when Star began to pull out, just to slide inside again, this time, though, the alpha’s walls constricted around the intrusion, putting both the user and stand in a painful position.
“Ugh- A-ah!” Jotaro gasped, suddenly very out of breath as Star tried to force its way inside. "W-wait- fuck!!” He cried as their hips met again.
“Hah… aghh-” Star Platinum groaned, a deep, raspy noise that made heat travel lower on Jotaro's body. “Gahg… ah..”
It took a second for Jotaro to catch his breath, but when he did, he found that his body wasn't rejecting Star Platinum as much as before. His hands found the hard biceps of his Stand before he signaled it to go on.
"I'll be fine,” Jotaro said. "Just- ugh-!”
Star Platinum had thrust forward harder than before, making Jotaro's eyes roll back as pleasure sparked in his belly when his prostate was grazed. His mind scrambled until the words wouldn't come out correctly and all that came out of his mouth were the incoherent sounds of his pleasure.
The air became heavy with the sounds of their sweaty skin meeting again and again in their instinctual need for one another. Despite being an alpha through and through, Jotaro found that he didn't care that much to be under Star like this, it seemed almost right to be the one taking it all.
Besides, it wasn't like he didn't enjoy it: every time Star thrust inside of his tight ass, Jotaro could feel everything on his own cock, which satisfied the alpha in him since it believed it was with an omega.
On the other side, Star Platinum couldn't tear its eyes from the beautiful man below him: his flushed face, teary eyes and glossy lips were driving it crazy. Every part of its being screamed that it needed to devour him, mark every part of his body as its own, to do anything that'll keep him by its side like this forever. Star leaned down and captured Jotaro's lips in a messy kiss, conveying more desperation than the overwhelming amount of love it felt.
“M-mhm,” Jotaro whined softly as his tongue tangled with Star Platinum's in a lustful dance that threatened to drive him right over the edge from the amount of passion he was subjected to.
Mortifyingly for Star, it felt something begin to swell on the base of its member, which was making it harder for it to push itself inside of Jotaro. Still, the Stand persevered and continued to ruthlessly pound its User with utmost precision to hit that spot inside that made him tighten around its cock.
“Ahh- mgh- hah.. Star-" Jotaro moaned after they separated. “Inside, cum inside…" he begged wantonly as his arms wrapped around Star Platinum's neck to hide his face in it.
Star didn't have a scent like a normal person, but its skin was soft and warm and it made him want to sink his teeth into it.
“I'm so close," he concluded right after. "but I can't let him, what if…?”
Jotaro's neck was practically calling to Star Platinum, and as it pressed its mouth to the skin to kiss it softly, its very first instinct was to bite down hard, but it refused. It'd never hurt its Master.
“Bite me.” Jotaro gritted out, his voice carrying an edge of desire that made it all the more alluring.
How could Star refuse its Master when he asked like that?
Just as the knot on his belly loosened, a sharp pain made itself known on his shoulder, which intensified after he sunk his teeth on Star Platinum's.
A small, pathetic sound escaped past his teeth when the base of Star's knot slammed against his rear, only for it to force its way inside, causing the man to release his Stand's shoulder in favor of gasping and clenching around the length uncontrollably, his body spasming violently after being locked with his Stand.
“A-agh! N-na.. oh!” Jotaro babbled as he felt warmth spill inside of his ass. Once Star Platinum locked them together, there was no way for its cum to leak out.
Compared to how overstimulated he felt before, this was torture. Jotaro couldn't even breathe with the monster cock pressed against everything inside of him, the violent assault of sensations only made him clench harder around Star Platinum and he broke down in strangled sobs. It hurt so much. He was already thinking of apologizing to all the omegas he’d criticized for being so whiny when he was younger, considering they had to endure this even more often with their partners.
He was pulled away from his thoughts by his Stand's gentle lips kissing his cheeks in an attempt to calm him down. Upon closer inspection, Star looked frightened, to say the least, as this was its first rut, but despite the confusion it remained dutifully still when it realized every little movement hurt their Master.
“Ora?" It asked in a short, breathy sound that made the man realize how tired he was after everything.
"It's fine, this is normal.” he conveyed mentally as any attempt to speak was futile. “Fuck- it hurts…”
Jotaro gasped when Star Platinum leaned down to lick at his neck in the spot he'd felt was warmer, and only then he remembered that it had bitten down to mark him. Regardless of instinct or whatever, Star seemed extremely apologetic as it kissed the wound over and over.
“It's… *huff* i-it's okay,” Jotaro reassured it softly. Every minute they stayed like that, he gradually got accustomed to the stretch, though it was still plenty uncomfortable.
Noticing that the knot wasn't going down, his Stand carefully slid its hand under his back and, very slowly, lifted his shaking form up, leaving Jotaro clinging to its neck for dear life. Star rest its back on the bedframe and settled Jotaro on its lap with his legs wrapped around its waist. Jotaro exhaled shakily at the new position, as gravity pulled him down further into the monstrous cock of Star's, but he found comfort in those big, warm hands that caressed his back with utmost care.
The relentless action had taken all energy from him, and he was left breathing softly against Star Platinum's chest while his eyes slid shut, abandoning consciousness to finally rest in the embrace of his double.
As the night air grew colder, Star Platinum slowly reached down to pull the covers over Jotaro's limp body, careful not to move too much to avoid disturbing his peaceful sleep.
It was maybe 15 minutes they spent stuck together like that, when the knot finally went down all the way and copious amounts of purple cum began dripping down Jotaro's ass. Star didn't want its Master to be uncomfortable, so it patted his back to wake him up before doing anything else.
“Ora," it whispered softly as it watched Jotaro's eyelashes flutter against its chest, making its heart beat with affection.
"Huh...?” Jotaro grunted before the memories came back to him. “Is it…?”
Star nodded, then it found itself holding two handfuls of his buttocks to lift him up and off of its flaccid member, feeling its Master tremble.
After feeling so full for so long, the emptiness was even more uncomfortable for Jotaro, but, at least, his carnal urges had been satiated. Now the only thing left to do was clean himself and try to get some rest.
As soon as he tried to get up, his knees buckled and he fell right back into Star's arms. His face burned with embarrassment as his fist tightened with shame.
“What the fuck am I doing?" His shaky voice cut through the silence.
Star Platinum wasn't bound by the same standards as humans, so while it didn't understand his distress, it sought to comfort him nevertheless through kissing his head.
"Ora ora,” Star said as it moved to stand up. Its legs were numb and it had to take slow, shaky steps towards the bathroom to avoid falling. It could feel Jotaro's face burn hotter against its skin, but it paid him no mind, focusing instead on helping its Master clean up.
. . .
Jotaro felt something cool hit his dry throat, finding Star Platinum's warm, comforting hand holding the back of his head to help the water slip past his lips. Star was holding him so gently, and from time to time it would put the glass down to cradle his face with more care Jotaro had thought he'd ever give in his entire life.
Once he had partially recovered, Jotaro brought his hand to the back of Star Platinum's neck, feeling for the matching bite mark he'd made during the session, and it was still there. Somehow that made him relax a little bit more, knowing that it would stay there as evidence of them. Next thing he knew, their lips slotted together like pieces of a puzzle as they moved against each other without rushing, enjoying the taste of their other half slowly, almost like a ritual.
When they broke off, Jotaro finally realized everything that had happened, and he covered his face with his hands to hide the growing flush on his cheeks. He laid down on his side, giving his back to the other to avoid his mortification growing even bigger. Star pulled the covers over them as it snuck its arms around his middle and spooned him, burying its face on the crook of his neck and inhaling softly.
Stands don't need to breathe, Jotaro had known that for a while, so the fact that his chose to just to be able to catch a whiff of his scent made him feel shy, and... owned, in a way. When had he become so submissive?
But… it was Star. He’s always had kind of a special bond with it besides them being basically one and the same. So… he supposed it wasn't a problem if it was just them.
