#miyacest osaatsu shibari

The ropes are crossed artfully over Atsumu's pelvis, a single line of cord running down between his ass cheeks and up the center of his cunt, bisecting his swollen lips, a thick double-knot resting snug on the hood of his clit.

Held in his lap, Atsumu

quivers with every teasing stroke Osamu bestows along the taut lines of braided nylon cutting into his waist, the juncture of his thighs, the diamond shapes framing his tits.

Osamu flicks the knot and Atsumu bucks, teeth clenched on a scream. He's so aroused he's dripping right

onto Osamu's gray sweats, darkening a spot along the thick outline of his cock.

Atsumu's legs shake where he straddles Osamu's thighs, back arched against his chest and hands bound behind his back. His body is on fire, hovering so close to the edge.

"What's the matter, baby?"

Osamu teases, one hand on the back of his neck and the other plucking his bindings like he's a cello being tuned before a big performance. He tugs on the cord leading down from Atsumu's navel, which rocks the knot up and down on his clit.

Atsumu whimpers, exhaling a wanton moan.

He thrusts against the knot and grinds against Osamu's length, near-desperate to be filled, to achieve release from this torment.

Osamu hums a kiss into the side of Atsumu's neck and fastens fingertips to his nipples, urging them to peaks with tight circles.

Atsumu writhes,

open-mouthed, shaking from this change in stimulation.

"Please!" he begs, squirming, hot breaths escaping from his throat.

Osamu rolls his hips, fitting his hardon in the valley of Atsumu's round tush and adding pressure against his hole. "Want something inside ya, huh?"

Atsumu groans lewdly, nodding his head. He rubs his ass on Osamu's lap, desperate for any friction.

"/Please/," he repeats, chest heaving with need.

Osamu strokes down Atsumu's taut stomach. His palm completely fits over Atsumu's cunt, trapping the knot, and he /squeezes./

The surge of sensation knocks the wind from Atsumu completely, mouth falling open on a silent cry.

"Don't hold back," Osamu taunts him. The next squeeze is tighter, forcing the knot and rope to get swallowed up by his pussy lips.

Atsumu wails, curling forward but he's held

firmly in place. The knot presses so hard on his clit he's scared he might actually cum.

Then Osamu lets go, draws his hand back and slaps it back down on Atsumu's pussy so abruptly his body jerks back and forth like a live wire. Before he can get his bearings Osamu does it

again, smacks his pussy hard enough for tears to sting Atsumu's eyes, his voice choking on a sob. The pain licks through him like wildfire, followed by a singularly sensual heat that toys with Atsumu's instincts. He sobs harder.

Osamu kisses the back of his shoulder and drags

his thumb over the knot and down the rope, now fully slicked by Atsumu's wetness. "Here you go," he says, pushing the rope aside and plunging his thumb inside Atsumu's swollen cunt.

Atsumu hisses, tongue pressing the roof of his mouth, elated to be filled by /anything/ at all.

He twists to rock down on Osamu's thumb, shuddering as the motion rubs the knot on his clit at the same time as the rope brushes back and forth across his asshole.

"Ahh, fuck, ahhh," he gasps, humping harder and harder.

"Christ," Osamu swears. He scoops Atsumu's legs up with

one arm, yanks down his sweats to free his rock hard cock, and settles Atsumu so the tip lines up with his juicy cunt. Atsumu greedily shifts his weight accordingly to accommodate when Osamu bucks his hips up and slots his dick all the way to the hilt.

"Fuck!" Osamu groans,

plunging into him at a fast pace. Atsumu throws his head back and bounces along with him, gasping in ecstasy. Osamu reaches around and taps on that perfectly placed double knot like it's a Morse code emergency message to Atsumu's clit - Atsumu cums as commanded, sobbing and

clenching ripples around Osamu's dick until he can't stand it, growling and holding Atsumu's hips in place to rut into him, shoving as deep as he can and cumming hard, spilling everything he's got.

"Don--don't stop!" Atsumu cries.

Osamu keeps flicking the knot until Atsumu cums

again, so worked up he can ride the cusp over and over, clenching tightly around Osamu's length. On the third orgasm Osamu hisses, his dick overstimulated by Atsumu's trembling cunt.

Spent at last, they collapse on the couch, spooning as Osamu's cock softens and his cum starts

to drip down Atsumu's legs from his warm, plump puss.

Atsumu cranes his neck to blow a kiss to Osamu. "Happy Valentine's Day, asshole."

Osamu snorts. "Don't worry, baby, I'll fuck you there too."

"Mmm, Happy Valentines day to /me/."
