Work Text:

It was a wonderful, sunny day, of birds chirping on the way to school, and the cherry blossom petals blooming all over. It seemed like a perfect day for Kakyoin.

Except for one thing.

Jotaro had missed school that day.

Jotaro wasn’t one for missing school. He only did that when it was something extremely important, like saving your mom from a life-draining vampire all the way over in Egypt. Good thing that’s already on the past. So what could have made him be absent today? Was he sick? Kakyoin pondered what could have happened.

When class was over, the teacher handed Kakyoin the extra homework for Jotaro since he missed school. Kakyoin was glad to have an excuse to go to his house so he can ask what was going on.

Once he arrived to the Kujo residence, Holly was always a delight to see.

“Ah Kakyoin-kun! What are you here for? To see Jotaro?”

“Yes, I came to bring today’s homework.”

“What a good friend Jotaro has! I’m so happy! Come on in Kakyoin-kun.”

“Thank you, Holly-san”

As soon as Kakyoin stepped into the household he could feel the air dampen around him. He felt the ambience about heavy around it, but he paid it no mind, maybe Holly was cooking something and the vapor was going out. Kakyoin took off his shoes at the entrance and went to Jotaro’s room.

“Be careful, please knock first because it seems he’s a bit sick today! Have fun!” Holly said as she went the other way.

So he was sick…? A cold? Jotaro almost never got sick. The closer he got to Jotaro’s room, the heavier the air was getting. There was also a smell Kakyoin couldn't recognize. It smelled good… but it was also making him kind of dizzy. He thought this experience was similar to when he walked near by an omega in heat on the street. So was someone in heat in the Kujo residence? Holly seemed to be fine. Could it be… Jotaro was an omega, and he was experiencing his first heat? And Holly was letting an alpha like Kakyoin go near him at this time…? Maybe Holly didn’t know Jotaro was an omega yet, because he’s still young. God, this was bad. Kakyoin couldn’t stop walking and following the scent and he knocked Jotaro’s door.

“Nn, I told you already, go away, bitch…”

Jotaro thought it was his mom outside and not Kakyoin. When he spoke he tried really hard to get his voice out normally. It was really hard with all the pheromones he was inhaling.

“Jotaro, it’s me.”

“K-kakyoin…? Why...”

Jotaro’s voice softened upon hearing Kakyoin’s. He seemed to be at a loss of what to do.

“I came to give you your homework from school... “

“...” Jotaro had a hard time talking too, not that that was uncommon, but now he was taking especially more time to answer.

“... And I wanted to know what happened to you because you usually don’t miss school”

“You asshole… You shouldn’t have bothered…” Jotaro said, but he opened his door a little as a sign for Kakyoin to pass.

The strong scent of pheromones leaking out was driving Kakyoin crazy. But he really wanted to see his friend, so he stepped in. Jotaro was leaning on his bed with a hand over his forehead.

“..Are you sick?” Kakyoin asked

“...You’re an idiot, but I know you’re not that stupid, Kakyoin...”

“...So you’re an omega?”

“...nn”

Jotaro was panting between his answers, and Kakyoin was getting hornier and hornier seeing him like this. He felt guilty, for seeing his first friend like this. He moved over to his desk to leave the homework, trying to not look at Jotaro, or god knows what he might do. The little noises he was making were already too much to handle for the boner he was growing.

“Alright, well…”

Jotaro grabbed Kakyoin’s uniform from his bed.

“Kakyoin, now that you’re here… You smell good…”

“That’s what I should be saying, ah, fuck… I shouldn’t…” Jotaro’s pheromones were absolutely delicious, he grabbed Jotaro’s hand back instantly.

“Kakyoin…”

Jotaro was practically moaning out his name. Fuck. He knows he shouldn’t, he’s his friend, but he always found him hot anyway, so why should he back off…? It seemed like Jotaro wanted it badly, too. It’s not like he couldn’t avoid letting his seed inside Jotaro, he was a composed man, more than Jotaro at least.

“C'mere…” Jotaro whispered as he lifted up his shirt with his other hand.

That was the last straw, Kakyoin plunged into the bed on top of Jotaro, smelling his chest and inhaling his pheromones.

“Your scent… it’s so intoxicating… I missed you at school today, Jotaro…”

Jotaro hugged him as he arched his back “Nnh..”

Kakyoin began humping his crotch against Jotaro’s “Look how hard you got me with how you are…” Jotaro was already rock hard, which was no wonder for an omega in heat. He was very wet down there, too. “Hm… let’s not get this wetter than it is” Kakyoin said as he began taking off Jotaro’s pants.

“Hot… ah... Feels hot, Kakyoin…”

“It does, but it’s good, right?...Can I kiss you?”

Jotaro nodded and as Kakyoin was done with his own pants he got on top and kissed Jotaro on his plump lips, already wet with his drool. He wasted no time on licking them and entered his tongue, Jotaro let out a moan at the intrusion. Kakyoin couldn’t believe Jotaro could sound so cute. They kissed passionately, exploring their mouths, as Kakyoin massaged Jotaro’s broad tits. “Do you like that?” Kakyoin asked breaking the kiss, and played a bit more with his nipples. "Hn..."

"So you're sensitive here too, huh.." Kakyoin began lapping at one of his nipples while twisting the other with his fingers. He hungrily sucked both of his nipples with his mouth and played with them with his skillful mouth. Jotaro's chest was dripping, and he was estacstic with the attention was receiving. Kakyoin was drinking up every last moan and sound that came out from Jotaro's mouth.

Kakyoin held Jotaro's bicep to lift it and approached his face there. He planted his face on Jotaro's armpit and gave some experimental licks. Jotaro was sweating so much, and his pheromone-filled sweat was making Kakyoin impossibly hard "Kakyoin, what…? Ah!" Jotaro exclaimed, looks like he really liked it. Kakyoin began sucking on the skin and licking away his sweat as like when he eats cherries while also masturbating both their hardons together. "Hnm.." Even Kakyoin was grunting because of tasting his omega's delicious pheromones. He could seriously lick Jotaro all over right now, he wanted to eat him. Jotaro was practically shaking from all his sensitive spots being touched like this. His cock was dripping cum excessively over his belly.

Kakyoin lifted his head from Jotaro's armpit to his ear and licked the shell as he whispered "Can't believe you liked that, Jotaro... you're lewder than I thought…" He kept reroing his ear. Jotaro was jumbling incoherent words, not knowing what to say. He was overexcited.

“Aah, I can’t take it anymore, touch my hole” He was such a sensitive one. And impatient.

“Hmhm, if you say so…” Kakyoin reached down to his hole and found it already extremely lubricated. He kissed Jotaro’s neck, then his chest, stomach… to his dick. Jotaro’s cock was big and thick for an omega, but Kakyoin couldn’t help but find that extremely hot. As he kissed the tip, he inserted a finger on his hole. “Ah!” Jotaro let out a yelp and shuddered at the overstimulation. Kakyoin gently bobbed his head up and down his cock while he fingered Jotaro. “Hurry, hahh, please…” It was so weird for Jotaro to beg, but that just made Kakyoin even harder. He wanted more.

"What was that, Jotaro?"

"What you heard…"

"I didn't hear you very well… you want this?" Kakyoin slapped his cock on Jotaro's thighs, balls and near his hole.

"Hah..! Yes! Fuck me..." Jotaro whined out

Kakyoins slapped his ass a couple of times before positioning his cock right at his omega's entrance. Jotaro was twitching and making cute noises all over.

“Good boy, here comes my dick, just for you”

Kakyoin plunged his alpha dick inside Jotaro in a strong motion, as he was losing his patience as well. Jotaro jolted and moaned even harder than before. He was panting as he got used to Kakyoin’s dick. This was Jotaro's first time after all, but he was clearly enjoying it, a bit too much. The heat and softness inside made Kakyoin’s mouth water. Jotaro started clenching around him, Kakyoin grabbed both his big thighs to press them against the omega and began thrusting inside his hole at a fast pace, giving a kiss to Jotaro. Kakyoin's hips and balls against Jotaro's legs kept the room filled with a loud horny sound.

“Kakyoin… harder…” Kakyoin complied, the wet slaps against skin becoming lewder. “Ah, Jojo, it’s so amazing inside, fuck…” Jotaro couldn’t stop moaning everytime Kakyoin hit on his deepest spot, pressing his head against the pillow in pleasure.

"Mark me"

Kakyoin pondered for a moment but his head was so hazy from Jotaro's sweet smell and the heat he was feeling around his cock that he just went for a bite right on Jotaro's star birthmark. He started slow and while he pounded harder he bit harder. Jotaro was impossibly aroused, he was letting out tears, his moans almost shrieking without a sound.

"You're mine, Jotaro… I love you… I have always liked you"

"M-Me too, Kakyoin, ah…"

Kakyoin was about to push his knot inside him.
Jotaro was hurting from how much it was stretching him. "I-inside…?"

"I'm so happy that you are an omega, Jotaro… you will have our pups"

"Aah, ahnn.." Jotaro didn't expect to get this for but he was happy too. He had been attracted to Kakyoin since a long while ago, and it was mutual… When the knot was fully inside and felt all of Kakyoin's seed pump inside of him, he came all over their abdomens. It was so much cum some was overflowing.

"You came so much baby…" Kakyoin said as he collapsed on top of Jotaro.

"You… I love you."

Kakyoin moved to Jotaro's back to make the big spoon and knot him from behind.Hierophant green's tentacles suddenly came to caress jotaro on his thighs. They stayed close to each other for a long while imagining their future together. Nothing else mattered in that moment.

"...I could help you do the homework later" Kakyoin broke the silence for a moment.

"... Shut up".

They were so exhausted they fell asleep like that.

The next day, Holly was making fresh orange juice for Jotaro and his friend. As he waited for them to wake up, Holly thought to herself "Looks like im a grandma now… I'm so excited!"
