****** Chaotic Curiosity ******
by apples4ryuk
Summary
     [or: Curio Asa T]
     Jotaro and Koichi are dating... Sort of. They were affectionate
     toward each other behind closed doors, because Jotaro would murder
     Josuke without hesitation if he opened his mouth to tease them. Their
     touches were innocent up until now, light kisses, hugs, cuddles...
     Koichi loved the nights he got to stay over with Jotaro. But a lovely
     morning wood wakes him and Koichi can't help his curiosity.

Koichi yawned, rolling over. The sun disrupted his blissful sleep through the
cold morning air. It brought no warmth to him, or maybe it did, but nothing
like the body next to him. He was awake now anyway, he thought, and blinked
open bright eyes to gaze at the face across from him.
 There was no denying Jotaro was gorgeous. Koichi watched his relaxed eyes
flutter in a dream, his thick eyebrows more straight than angled when he wasn’t
working or stressed out. His nose was longer and pointed, a trait he might’ve
inherited from his Italian-English mother. And his lips, oh, those wonderful
lips… Koichi reached forward to trace them with his forefinger. They were thin,
but soft, and small. Koichi’s hand shied away when those lips gently kissed his
fingertips.
 “Koichi.”
 He shivered and pretended to be asleep. Jotaro’s Adam’s apple bobbed when he
spoke, and Koichi knew it vibrated with his deep voice. Hearing it groggy and
full of lazy exhaustion was a rare occurrence that Koichi would hold in his
heart forever.
 And Jotaro’s laugh. Well, it was less a laugh and more an amused exhale of air
through his nose this early in the morning. Regardless, Koichi loved it. He
felt the air blowing on his face and arms engulf him, pulling him closer.
Jotaro’s lips touched his forehead.
 “Go back to sleep,” he said. Koichi only nodded, but as he was held closer he
felt Jotaro’s length poking against his leg. He clutched onto the large man’s
shoulders and buried his face in his chest. Jotaro’s warmth was so lovely.
Koichi was slipping back into his dreams, at least until Jotaro adjusted again.
His half-hard cock was still rubbing against Koichi.
 He couldn’t deny he was curious… He wanted to touch it, had thought about it
more often lately. He chalked it up to teenage hormones but now that he was
this close to Jotaro, Koichi wanted to—to see what it was like to feel someone
else’s cock in his hand…
 He lightly dragged his hands down Jotaro’s torso. He didn’t seem to notice, so
Koichi kept going. He stopped right at the hem of Jotaro’s undies… Boy, Koichi
would’ve never guessed that someone like Jotaro would wear tight boxer-briefs.
He was grateful for it, able to enjoy a peek now and then when Jotaro came to
bed. And now, slipping his forefinger beneath the elastic, he could enjoy
feeling it too.
 Jotaro made no movement, his lips parted to filter out even puffs of air.
Koichi hesitated. He held his breath and waited for any response – none. He
pushed Jotaro’s underwear down around his cock and felt his heart beating
wildly in his chest as he took hold of it.
 A hum escaped Jotaro’s mouth, but he didn’t open his eyes. Koichi bit his lip,
the base of Jotaro’s cock was warm in his hand. He moved lower and rolled
Jotaro’s balls in his palm, groaning softly.
 “Nnnh…”
 Jotaro still wasn’t awake. Or maybe he was, Koichi knew by now how perceptive
the older man was, he almost never missed a thing. God, the velvety feel of his
balls and the soft, fluffy hair there made Koichi want more. His face was hot
red as he scooted down, pushing the sheets off his sort-of-boyfriend’s lower
half.
 G… Geez… Koichi figured Jotaro would be big, given his height and immense
bulk, but his cock was thick even while it was soft. He couldn’t help himself
and stroked up and down, slowly, ears tingling from sounds Jotaro was
unconsciously making.
 “A-ah… Koichi… what--?”
 Or not. Shit!
 Koichi didn’t say anything, stroking a little faster. Jotaro hissed and rolled
onto his back, breathing heavily. “What… what are you…”
 He couldn’t get any words out, and Koichi liked that. It might’ve meant he was
doing okay. He wondered how long it had been since Jotaro was pleasured,
anyway. Koichi got himself off more times than he’d ever admit, but Jotaro was
always about work, work, work. He learned that Jotaro studied marine biology,
and if he wasn’t out finding Stand Users he was working on his thesis. Koichi
was allowed to look through his many pocket notebooks, filled with extensive
notes and research and all sorts of sea-life sketches.
 So when did he have time to please himself? Koichi’s body rose in temperature
and Jotaro was clutching the sheets now. He felt some sort of accomplishment
well up inside—he’d never helped anyone else get off before, or had sex at all
– yet –and Jotaro was much older than him, and Josuke, and Okuyasu. Jotaro
probably had someexperience compared to all three of them, especially Koichi.
But he wondered if he was doing good, if he was capable of reducing the stone-
faced man to a tense mess in his hands.
 Jotaro was completely hard now, just from a few strokes. Koichi blushed, his
hand looked small around its full length, a marvel to see. He could see the
shaped vein protruding from the side and little curly hairs all around the
base.
 Koichi hummed. Jotaro hadn’t stopped him yet and his cock suddenly looked…
appetizing. Koichi wasn’t confident, didn’t know what to do, had only imagined
what a hot, moist tongue would feel like around his dick. But, he licked his
lips, and bent his head down to lick the tip of Jotaro’s cock.
 Jotaro sat up immediately, tugging at Koichi’s messy hair.
 “K-Koichi,” he said, breathless. Koichi looked up through his eyelashes, face
all red, cheeks trembling. “What are you doing?”
 “…I wanted to touch you,” he admitted, breaking eye contact.
 “Why?”
 “I just… was really curious,” Koichi said. “B-but I’ll stop if you want, I’m
so sorry, Jotaro!”
 “No, don’t,” Jotaro said. “But if you bite me I won’t let you touch it again.”
 “…Y-yes, Jotaro!”
 Jotaro sighed and sat up, arranging the pillows against the headboard so he
could lean on them. With his thighs spread he was even more gorgeous, Koichi
thought. Part of him felt like a pervert but he settled easily between Jotaro’s
legs, grinning a little at the man’s refusal to look straight at him. His eyes
were closed and brows pulled into a concentrated fashion. He was so cute, too.
 Koichi took a deep breath again and descended onto Jotaro’s cock. He stuck
with the head, first, experimenting with how it felt and tasted in his mouth.
It was mostly dry, he didn’t use any lube when he was jacking him after all,
but one swipe of his tongue across the top caused Jotaro’s legs to tense.
Koichi felt his thighs inching closer, just by a smidge. He took his mouth off,
still unsure what he should do or whether it mattered to have a particular
order to do things in. Jotaro tasted… like skin, Koichi thought, nothing too
different than when he’d lick food off his fingers and palm as a child.
 But it was a raw flavor, he decided, probably concocted from the sweat and
salty air that made Jotaro smell musky all the time. Koichi imagined it
marinating in his loose pants, and that the tight underwear probably didn’t
help with that. Koichi thought he’d be more grossed out than turned on by these
thoughts, but Jotaro didn’t smell bad or taste bad.
 He poked his tongue out and dragged it on the underside of Jotaro’s length. A
quick sound that he nearly missed caught his ears, so he did it again, taking
his time. He lathered Jotaro’s cock with saliva until Jotaro’s fist left the
sheets and tugged on Koichi’s hair again.
 “O-ow! I—I didn’t bite it!”
 “Just eat it,” Jotaro said. Koichi turned even more red, if he could at all.
“Eat it. Now.”
 Koichi nodded numbly and wrapped his hand around the base. His fingers
couldn’t touch around it, and his nerves should probably be bundled up insanely
right now, but Jotaro had commanded him to eat his dick. It was too sexy for
Koichi and without thinking, he took as much as he could to the back of his
throat.
 He choked, naturally—Jotaro said something from above but it was to deaf ears.
Koichi breathed heavily from his nostrils and took a little less, letting his
throat catch his breath. He used his tongue in the meantime to lubricate
Jotaro’s length—he tasted salty as expected, like the ocean, and he had likely
gone swimming at the beach earlier this week. Maybe the sea water stuck on him,
maybe he hadn’t showered after all—but Koichi ignored all of these pointless
thoughts and started slowly bobbing his head up and down.
 Jotaro’s hand was still in his hair. He felt him grasping, rough then gentle,
as if he had to remember that a living being was attached to the hair he was
pulling on. Short breaths and long sighs, Koichi heard it all, and it made his
boxers a little tighter. He moaned around Jotaro’s length, wondering how it
looked to the man above him. How it must’ve been torture to watch his cock
disappear into Koichi’s mouth so, so slowly.
 He was too big to fit entirely inside his mouth, Koichi realized. He twisted
his hand up and down the untouched part of Jotaro’s length at the base. Every
time he hummed or breathed and let little sounds of pleasure come from his
mouth, Koichi felt the vibrations down Jotaro’s length. Jotaro’s hand would
squeeze when he did, and he’d bob his head a little faster.
 “Ah… Hah—ahh… Koichi… mm…”
 Encouraged by Jotaro’s enjoyment, Koichi tried to take a little more in his
mouth anyway. His cheeks were hollowed and aching as he sucked on Jotaro’s
cock, tasting a saltier substance at the back of his tongue. His throat was
still tight and wouldn’t relax, but Koichi wanted to suck him really good,
wanted Jotaro to fuck his mouth. He was already thrusting lightly, holding back
because Jotaro’s cool exterior only hid his secret considerate nature. Koichi
was lopsided, leaning on one elbow as he let go of Jotaro’s cock and breathed
heavily, still stroking him from base to tip.
 Koichi used his tongue as he rested, the other hand already in his boxers,
pumping his own hard length. Koichi swallowed up Jotaro’s precum with furrowed
brows, sucking on the tip only. He watched Jotaro’s sweat drip down his abs,
then along the crease of his V-shaped hips. Koichi clenched his eyes shut and
tried again, taking Jotaro in ‘til he hit the back of his throat. He’d gained a
bit of control now, relaxing his gag reflex for but a moment. It closed on him
quickly and he choked, but Jotaro was thrusting now and Koichi couldn’t really
stop it. His body was pushed down the bed as Jotaro’s moved, too, until the
larger man was laying on his back and thrusting up into Koichi’s mouth. Koichi
widened his jaw as far as it could go, tears in his eyes as they clenched shut.
He moaned around Jotaro’s wide cock and stroked himself, eyes blearily blinking
to watch. He wanted to witness Jotaro’s pleasure for himself, unable to believe
it was caused by his own doing.
 And he did: Jotaro’s eyes were on him, his cheeks red and glistened with
perspiration. Koichi could see his pecs sticking out, as if they craved
attention, too. He’d have to remember to try those next time. But Jotaro was
thrusting harder and Koichi almost gagged and puked, so he closed his eyes
again and focused on finding release for himself.
 A few more strokes, then Jotaro grunted, “K-Koichi,” and he came from that and
that alone, spilling all into his boxers and on the sheets. His hand was sticky
around his length but Jotaro wasn’t done yet, not until his thighs were shaking
under Koichi’s other hand. He shuddered and pulled Koichi’s mouth off as he
came, splattering white liquid all over Koichi’s face.
 It was warm fluid, a little too warm for Koichi’s liking—but the look of pure
satisfaction on Jotaro’s face was well worth it. Koichi waited until Jotaro had
completely spent the seed from his cock, then licked off a bit that dripped
down onto his lips.
 “It’s kinda… tasty,” he said quietly. Jotaro chuckled and leaned sideways,
grabbing some tissues from the nightstand. He wiped off Koichi’s face, and
handed him more to clean his hand.
 They remained in bed, though, Koichi resting his head on Jotaro’s chest. His
pecs rose slowly with each breath, and Koichi felt sleep lulling him in again.
 “Will you go back to sleep now?” Jotaro asked. Koichi blushed, hugging his
side closer.
 “Yes,” he mumbled into Jotaro’s ribs.
 Though the morning light had risen already, they stayed in bed until around
noon. Neither cared to get up and clean, or to talk about what had happened.
They let it be and peaceful dreams came to them, a moment of sweet release from
their otherwise chaotic lives.
