Kinktober 2025 - Day 1: Somnophilia (saeyuki)

Summary:

“Fuck…” Sae was totally bricked. At the worst—most inopportune time ever. He had just gotten back from his morning run, and was returning back to his penthouse in Madrid.

Yukio was staying over for the week—and had just gotten off of the plane, busy sleeping his exhaustion away. It would be rude of Sae to… Y’know—especially with permission from three years ago.

He’d even jerked off in the bathroom after getting home, but he was still so goddamn hard it HURT.

“Screw it.” Sae mumbled incoherently as he stalked into the bedroom, emerald green gaze immediately latching onto Yukio. Unlike his shitty boyfriend (hopefully soon to be fiancée if the striker would have him), he would rather die than find pleasure in another man.

Moving on.

Work Text:

“If you ever want to do anything when I’m out, that’s fine.” -Isagi Yukio, ~3 years ago.

“Fuck…” Sae was totally bricked. At the worst—most inopportune time ever. He had just gotten back from his morning run, and was returning back to his penthouse in Madrid.

Yukio was staying over for the week—and had just gotten off of the plane, busy sleeping his exhaustion away. It would be rude of Sae to… Y’know—especially with permission from three years ago.

He’d even jerked off in the bathroom after getting home, but he was still so goddamn hard it HURT.

“Screw it.” Sae mumbled incoherently as he stalked into the bedroom, emerald green gaze immediately latching onto Yukio. Unlike his shitty boyfriend (hopefully soon to be fiancée if the striker would have him), he would rather die than find pleasure in another man.

Moving on.

The redhead cautiously pulled one of the plentiful blankets off of Yukio’s head—feeling his heart skip a beat at the dark haired man’s peaceful expression.

God—he loved Yukio so much.

Slowly, he used one hand to move the blankets away, while the other reached for the lube he kept stashed in his nightstand.

The cold—slippery gloss glistened as he pumped a small amount into the palm of his hand, letting it warm up—before hauling one of yukio’s legs over his shoulder, lubed hand reaching to snake beneath the long haired man’s waistband.

With a shaky sigh, he eased his hand along Yukio’s crotch, tracing alongside his genitalia—sinking two fingers into his ass.

“nngh.”

Sae froze—immediately stopping his ministrations as Yukio let out a soft whine—checking if the Isagi was awake.

Phew. His sapphire eyed burden was still knocked out.

“How reactive,” Sae mumbled, gently scissoring Yukio open, leaning down to nip at his pierced earlobe.

It only made Sae want to go further.

.

.

.

When Isagi Yukio woke up, he was still on his side—and everything felt… normal.

Did it?

A strange, warm sensation filled him—his back felt like it was burning and it felt so goddamn good , he felt so full.

“…ouh-!”

Was that his voice?

It took him a few moments to come to… before—

“Shit—hah—you’re awake,” a voice grunted from above him. Yukio’s leg felt sore, was the disembodied voice holding his leg up?

“sae—♡?”

“Mornin’ Yuyu—missed me?“ Sae grunted out, still continuing his strange movements, causing the coil in Yukio’s stomach to tighten even more… god… it felt so..

“feels—mmm… feels good.”

Yukio slurred quietly, cheek still pressed to the pillow, hands weakly gripping a soft blanket to pull up to his face—taking a deep breath.

‘It smelled like Sae,’ his half conscious mind noted, before nuzzling his face into the blanket. The feeling in his stomach didn’t go away, but lulled him back to sleep. A pleasurable, gasping sleep.

“That’s it. Good boy. Close your eyes—love you baby. Goodnight.” Sae cooed from above him (he loved Sae so much), reaching to wrap a calloused hand around Yukio’s reddened cock, thumbing around the tip.

Yukio let out a whimpered moan as Sae pressed down on his slit—automatically responding with a subdued: “ah… g’night…”

.

.

.

…close call.

Sae pressed a gentle kiss to Yukio’s hairline as the striker conked out once more, before moving down to nibble at his tattooed collarbones—lips tracing along the thin lined star tattoos along the two protruding bones—hips moving slowly.

His hand dug into the muscle of Yukio’s thighs, holding it in place over his shoulder as his he continued stroking the raven haired man’s dick, watching with morbid (horny) intrigue as it twitched and shuddered.

“…so goddamn cute,” he muttered to himself, squeezing his hand around the twitching thing even harder—before letting go (but not without giving it a little flick afterwards).

“ngh..”

Sae felt a shudder of arousal go down his spine at Yukio’s whispered moan, such a wanton, rare sound from his darling’s usually sharp tongue.

His movements were slow, almost languid, as he fucked into his boyfriend's ass—breathing slow and slightly burdened—before turning Yukio onto his back, massaging his abdomen.

“c’mon… cum f’me.”

Sae felt his orgasm coming—and he was determined to get his (far from) perfect boyfriend to “come” with him.

Maybe it was out of instinct (or more likely, after getting it on with Yukio for over three years now), but Sae could tell that his lover was about to cum.

“Not so fast—haha—so impatient...”

He reached down to clamp a hand firmly around the base of Yukio’s dick, thumb placed directly over his slit.

“nouuh- oowwwwhh—“

Yukio protested weakly, arms reaching up to flop over his eyes—face scrunching into a puffy pout.

God. He was so bratty, even when asleep.

‘I should fix that.’

Sae made a mental note to correct Yukio’s attitude, before speeding his hips up.

The previously warm and uncomfortable heat in his stomach had turned into a genuine, burning ache for a release that he chased with (mild) guilt.

“s-sorry for taking advantage of you when you’re asleep, Yuyu,” he strained, too preoccupied with chasing his own, primal lust. “But you said I could—so I am. You won’t hate me after this, will you?”

He chuckled to himself, turning to bite Yukio’s thigh, feeling sweat bead and drip down his forehead.

“Fuuuuck—“

Sae let out a low groan as he came inside of Yukio—releasing his grip on the man’s dick he did so, leaning down to claim his lover’s lips on a bruising kiss.

“Mhhh. Love you—s’much.”

He mumbled, sloppily lapping at the inside of Yukio’s limp mouth.

“I’ll clean you up good—y’wont even find a drop of me when you wake up, kay?”

At this point, Sae was speaking to himself—but who cares. He needed to affirm his sleeping beauty.

“You did s’good. So sensitive—so adorable.”

After finally finishing peppering Yukio’s face with sloppy kisses, he finally pulled back—“removing” himself from Yukio’s dripping hole, watching as hot cum leaked from his abused ass.

A part of him was tempted to try to shove it all back in, but even the thought was getting him hard again, and he didn’t trust himself to not wake Yukio up the second time.

The striker needed his beauty sleep, after all.

With a longing shake of his head, Sae retreated into the bathroom, returning with a wet cloth to wipe Yukio off.

Afterwards:

Y: “Sae, did you do something when I was sleeping?” (Eating cereal)

S: “Did I?” (Suspiciously smug)

Y: “…whatever. My butt hurts.” (Pouring another bowl of cereal, milk first)

S: “Pour the milk first again, and I’ll make sure it hurts more next time.” (Deadpan; grabbing training gear to go work out)

Y: “I hate you.” (Affectionate)

S: “Lukewarm response, as usual.” (Leaving penthouse)

Y: (Glaring at Sae as he leaves—vowing to get his revenge)

Y: (rat clenches fist of rage here)

Notes:

HELPPP
