The first thing Itoshi Sae notices when he steps out of the shower is warmth.
Not the artificial warmth from the bathroom steam clinging to his skin, nor the soft heat from the apartment heater humming quietly in the corner.
No.
It’s him.
Curled beneath a mountain of blankets on their bed is Shidou Ryusei, drowning inside an oversized cream-colored fluffy robe that looks more blanket than clothing. His long pink hair spills across the pillows and down his chest in messy waves, strands brushing the toned lines of his stomach where the robe hangs loose. The sleeves are too long, swallowing his hands entirely.
He looks soft.
Warm.
Safe.
Sae pauses in the doorway, towel hanging around his neck as cold water still drips from silver lashes.
For a second, he simply stares.
It still surprises him sometimes.
The fact that someone like Ryusei exists at all.
Someone whose skin is always unbearably warm, whose laughter fills entire rooms, whose smile reaches people before his words do. Someone who burns so brightly that others naturally orbit around him.
The complete opposite of Sae.
Sae remembers when they first met at eighteen.
People used to flinch the first time they touched him.
“Jesus, your hands are freezing.”
“You’re cold as hell.”
“You ever feel anything?”
Eventually the comments stopped bothering him. They were right, weren’t they? His body was cold. His personality wasn’t much warmer. Most people decided what kind of person he was before even trying to know him.
Distant.
Untouchable.
Too cold to love.
But Ryusei—
Ryusei had grabbed Sae’s wrist on the second day they met and grinned like he’d discovered something fascinating.
“Woah! You’re like ice cream!”
Sae had stared at him blankly. “What?”
“That’s sick,” Ryusei said brightly, still holding his wrist despite the temperature difference. “You can cool me down during summer.”
No hesitation.
No discomfort.
Just warmth.
Always warmth.
And somehow, years later, Ryusei still looked at him the same way.
A sleepy voice breaks Sae from his thoughts.
“You gonna stand there all night, pretty boy?”
Ryusei peeks at him from beneath the blankets, pink eyes half-lidded with exhaustion. Even now, at twenty-one, he’s still shorter than Sae, only reaching around his shoulders whenever they stand together.
Sae feels something ache softly in his chest.
Without a word, he walks toward the bed.
Ryusei immediately squints suspiciously. “Why do you got that look on your face?”
Sae ignores him.
He climbs onto the mattress, knees sinking into blankets, then reaches forward and unzips the robe in one smooth pull.
“Oi!”
The robe loosens instantly. Revealing Ryusei's tanned bare body.
Ryusei sputters while Sae slips both arms around his thin waist and yanks him close without warning.
“SAE— your hands are freezing!”
Sae buries his face directly into Ryusei’s nape anyway.Saes hands travelled around Ryusei’s naked body finally deciding to rest them on his waist.
Warm.
So warm.
It seeps into his skin immediately, thawing him from the inside out.
Ryusei wiggles dramatically in protest. “You’re literally an iceberg— agh, quit shoving your cold feet on me!”
“Move less.”
“You move less!”
Despite the complaining, Ryusei’s arms slide around Sae automatically. One hand disappears into Sae’s damp hair, nails scratching lightly against his scalp. Ryusei’s warm tan body felt like heaven compared to Saes icy cold bare body even though sae just came out of the shower .
Sae melts further into him.
The scent of his omega pheromones wraps around him softly — Peaches , Honey and cream —comforting, sweet, home.
Fated mates. Ryusei’s sweet scent was always the perfect contrast to Sae’s scent of vanilla and matcha and sea salt. Sae’s scent felt more elegant and colder while Ryusei’s let out all the warmth Sae never knew he needed.
Sometimes Sae still thinks the universe made a mistake giving someone as radiant as Ryusei to someone like him.
Ryusei tilts his head slightly, long blond hair with pink tips falling by his side , while his money pieces were brushing Sae’s cheek.
“You’re clingy tonight,” he mumbles.
Sae tightens his hold around Ryusei’s waist.
“Mm.”
Ryusei laughs quietly. “That’s not a denial.”
Sae doesn’t answer.
Instead, he presses closer until his cold nose nudges against warm skin. Ryusei lets out another exaggerated whine but shifts willingly, opening the blankets wider so Sae can fit against him completely.
Like he always does.
Like he always will.
After a long silence, Ryusei speaks softly into the dark room.
“Y’know… I like that you’re cold.”
Sae opens one eye slightly.
Ryusei smiles sleepily.
“Makes it easier to tell when you need me.”
For once, Itoshi Sae has absolutely nothing to say.
But the way Ryusei’s scent smelt sweeter … and Fresh and warm. It welcomed Sae into his embrace .
Shit. Sae didn’t even realised how much it turned him on until he felt Ryusei’s hand softly caress his shaft.
“ Does my scent really turn you on that much baby ? “
Ryusei whispered sultry and teasing in a way that made Sae’s dick visibly twitch in his omegas hands
Sae was so close to losing his control if Ryusei kept on doing that.
“Well Sae-chan ? “ Ryusei teased gently taking Sae’s hands and moving them into his heat.
His eyes widened as he felt the slick coming out of his omegas cunt drip onto his hands.
Sae lost it .
He grabbed Ryusei’s wrists and pulled them over his head , then grabbed the tie he was going to wear tomorrow for his meeting , using it to tie his wrists to the headboard.
“ Shit, Ryu can I . Please. “ Sae looked down at Ryusei listening to clearly evident in his eyes
Ryusei chuckled softly at Sae’s eagerness but that was quickly interrupted when Sae kissed him hard
It stole his breath away.
“ Sae-chan , baby …. what is up with Ahhh ~ ♡ you today ? Mhh ~ ♡”
Sae ignored Ryusei’s question entirely already too far gone to even do anything other than what his instincts told him to .
Sae settled in between Ryusei’s legs and spread him open for only him to see . He then pushed a finger inside the wet heat .
“ SAE ~ ♡ ! “
Sae couldn’t hold it in anymore and and shoved more of his fingers in thoroughly stretching his mate out to take his dick .
Ryusei’s moans grew louder and louder.
“Sae-chan , I’m about to cum baby AHHH ~ ♡, please let me cum baby .”
“ Not yet Ryu “ Sae managed to grunt out clearly already wanting to skip the prep and just go straight on with it .
Ryusei couldn’t do anything but try his best to stop himself from cumming.
But finally he felt a bigger, hotter object struggle its way into his cunt .
“ Fuck Ryusei , why are you so tight ? “
It wasn’t that Ryusei didn’t know how to answer that question it’s just that he physically couldn’t . All Ryusei could think about was his alpha fucking him .The way Sae’s dick wasn’t even halfway inside him but Ryusei already felt so full.
Finally Sae settled inside Ryusei’s cunt . Slowly rocking his hips to give Ryusei some time to adjust to his size .
“ SAE JUST FUCK ME ALREADY ! “ Ryusei was getting really impatient and quite frankly so was Sae .
Sae pulled his dick out all the way before ramming it back into the warmth of his mate .
Ryusei felt heavenly. His insides were so soft and sloppy and hot . So , so hot . Ryusei’s moans were increasing an octave every hard thrust Sae did.
Without even realising it , Ryusei tried squirming away but Sae held him closer , not letting him go
Ryusei was in bliss with his fiancè’s dick slamming into him. Ryusei never wanted Sae to stop .
“ S-Sae , please let me cum now , please b-baby ? Mhh ahh ~♡”
Ryusei was so close to cumming all over saes cock but was stopped when he felt the pleasure stop .
He looked up to see Sae staring at him with a look that could only be described as awestruck . Ryusei was about whine about why Sae stopped but was rudely interrupted by Sae’s dick hitting his womb on repeat .
Shit .
Ryusei was lost in all of these sensations until he felt a hand rest above his stomach.
Ryusei opened his teary eyes and looked to see Sae’s hands resting on the bulge in his tanned womb. He held his eye contact with Sae for about 10 seconds before Sae smirked and pressed down hard on the bulge whilst continuously thrusting deep into his cunt . Ryusei screamed Sae’s name . He was certain he wouldn’t be able to walk tomorrow.
“ Why the fuck do you need to be so fucking perfect Ryusei ? “ Sae’s eyes met Ryusei’s teary ones . “ You feel perfect , you look perfect , your hearts perfect . You’re just so fucking perfect it hurts you know that ? “
Ryusei couldn’t hold his tears anymore , letting them fall. His back bowed at the intense movements of his fiancè’s dick ramming hard into him . The sound of skin slapping skin and the lewd , wet noises or His slick turned him on so much more . Sae moved his head down and kissed them off savouring the taste .They didn’t know exactly how long it’s been since they started but being highly trained athletes with a whole lot of stamina came with huge benefits . One of them including lasting longer while having sex .
Sae felt his knot getting bigger and bigger until it was about to burst . He looked down at his fucked out mate . Said Nate stared up at him before yelling
“ INSIDE P-PLEASE SAE PLEASE , AHH~♡ !!”
Who was sae to refuse such an appealing request .
Sae slammed his knot , now the size of a fist , into Ryusei's sensitive entrance and watched as his mate yelled his name one more time before his body fell on the bed .
Sae untied Ryusei’s wrists and then rested above him for a while letting his not go down before he pulled Ryusei with him to face him while Sae laid down on his side pulling Ryusei flush against him without pulling out and holding his tired sleepy frame as close as possible .
“ Sae - chan “
“ Yes Ryu ? “
“ Are you warm now ? “
Sae looked down at his mate as said mate stared up at Sae with his wide doe eyes . Sae softened instantly .
“ I’m as warm as it can get , Ryu “
Ryusei smiled softly before yawning and hurrying hinself into saes neck as his arms encased his neck. meanwhile sae moved forward resting his head against Ryusei’s nape with his arms wrapped around his waist.
Sae looked down to see Ryusei’s snore softly . It was adorable .
Slowly listening to the sound of his mates snores Sae fell asleep right after .
For once in his life Itoshi Sae finally found himself truly in peace .
