Chapter 3: The Slut's Challenge
The grey light of dawn did nothing to soften the edges of the closet. It crept through the high window, turning the mirrors into sheets of dull metal and painting the velvet in shades of ash. Sukuna was already awake. He’d been watching them sleep for the better part of an hour, his mind blissfully empty of everything but the weight of Yorozu’s leg thrown over his and the soft puff of Megumi’s breath against his collarbone.
He moved when the stiffness in his muscles became a demand. A shift, a roll, and he was sitting on the edge of the chaise, the marble floor cool under his feet. The movement woke Yorozu instantly. Her eyes slit open, dark and knowing, missing nothing.
“Leaving?” she mumbled, voice raspy with sleep. There was no hurt in it, just a lazy curiosity.
“Making room,” he grunted, nodding to the space he’d vacated.
Yorozu understood. She uncurled herself with a feline stretch, her back arching, and then she slid into the warm hollow Sukuna had left. She wrapped herself around Megumi, who sighed and nuzzled into the new source of heat without waking. Yorozu looked up at Sukuna over the curve of Megumi’s shoulder, a silent question in her raised eyebrow.
He just stared back, his gaze traveling from Yorozu’s smug face to Megumi’s tranquil one. The quiet tenderness from last night was gone, burned away by the daylight and a more familiar, gnawing hunger. Seeing them tangled together without him—it lit a fuse somewhere low in his gut.
He reached out, not for Yorozu, but to brush a stray lock of hair from Megumi’s forehead. Her eyelids fluttered.
“Nii-chan?” she whispered, disoriented.
“Go back to sleep,” he said, but his tone was a command that promised the opposite. His thumb stroked her lower lip.
Yorozu’s hand slid down, under the silk sheet, finding Megumi’s hip. “He’s being greedy again, Gumi-chan,” she whispered, her lips against Megumi’s ear. “Wants his toy back.”
Megumi’s blush was instant, a bloom of color in the grey light. She was awake now, her doe eyes wide, glancing between Sukuna’s intense stare and Yorozu’s grinning face.
Sukuna stood. The full, rigid length of his arousal was blatant, casting a shadow on the rumpled velvet. “Up,” he said, the word leaving no room for debate. “Both of you. Now.”
There was a frantic, delicious scramble of limbs. Yorozu was out of the chaise in a heartbeat, naked and unashamed, pushing her short black hair back from her face. Megumi was slower, clutching the sheet to her chest, her movements still soft with sleep.
Sukuna didn’t wait for them to organize. He grabbed Yorozu by the back of the neck and kissed her, hard and deep, a reclamation. When he let her go, she was breathless. He then turned to Megumi, pulling the sheet from her weak grasp. He cupped her face, his touch softening just for a second before his mouth covered hers. It was sweeter than the kiss he’d given Yorozu, but no less possessive.
“On the chaise,” he ordered, his voice gravel. “Yorozu, here.” He pointed to the floor in front of it before sitting back against the plush cushions.
Yorozu’s smirk could have powered the city. She understood the assignment before he’d finished giving it. She climbed over him, her knees sinking into the cushions on either side of his head, lowering herself until her warmth hovered just above his mouth. She looked down the length of his body, her gaze hungry.
Megumi hesitated, her eyes on the junction of Yorozu’s body and Sukuna’s face, a flicker of something anxious and awestruck in her expression.
“Gumi,” Sukuna said, the name a low warning. “Don’t make me ask twice.”
She moved then, climbing astride his hips. She was so slight over him, all trembling thighs and shallow breaths. She guided him inside with a shaking hand, a sharp, sweet gasp escaping her as she sank down, taking him to the hilt. Her head fell back, a silent cry on her lips.
“Fuck,” Sukuna breathed out, the word vibrating against Yorozu. He let his head fall back, his tongue finding her without further preamble, a languid, thorough stroke that made Yorozu jolt and moan.
The rhythm was established not by Sukuna’s hips, which remained still, but by Megumi’s desperate, rising falls. She set a frantic, clumsy pace, her small breasts quivering with each movement. Her whimpers were tiny, broken things.
“Faster, Gumi-chan,” Yorozu moaned, grinding herself against Sukuna’s mouth, her hands braced on the chaise’s back. “Come on, let him feel you. You’re so good, so tight for him, I can see it.”
The filthy encouragement worked. Megumi’s movements became more deliberate, her hips rolling, finding an angle that made her eyes lose focus. Sukuna’s hands, which had been resting on Yorozu’s thighs, slid down to grip her ass, pulling her harder onto his tongue. He was a man drowning in sensation, split between the slick, clenching heat surrounding his cock and the musky, familiar taste of Yorozu on his tongue.
He pulled his mouth away just long enough to growl, the sound raw and shredded. “You’re both mine. Don’t you fucking forget it.”
It was the possessive rumble, the total certainty of it, that shattered Megumi. A high, thin cry ripped from her throat as her body convulsed, her inner muscles clenching around him in frantic, fluttering pulses. She collapsed forward, catching herself on his chest, her entire frame shuddering.
Her climax triggered Yorozu’s. With a ragged shout, Yorozu ground down one last time, her body bowing as she came, her release spilling hot over Sukuna’s chin and mouth. He held her there, drinking her in, until her tremors subsided into weak, boneless shakes.
For a moment, there was only the sound of three people gasping for air.
Then Sukuna moved. In a surge of power, he flipped his body, dislodging both of them. Megumi found herself on her back, pinned beneath his immense weight before she could even process the movement. Yorozu tumbled to the side, landing on her knees beside the chaise, her chest heaving.
Sukuna was still buried deep inside Megumi, his own release held at bay by sheer will. He looked down at her, at her wrecked, blissful expression, then turned his head to Yorozu.
His cock, slick with Megumi, glistened in the dull light as he pulled out. He fisted himself, giving one rough, slow stroke.
“Clean her up,” he ordered, his eyes locked on Yorozu’s.
Yorozu didn’t need to be told twice. She loved this part. She leaned in, her tongue following the path of his hand, licking the mixed taste of them from his skin. She took him deep into her mouth, humming with pleasure, her eyes closing in obscene delight.
Megumi watched, mesmerized, her breath catching. The sight of her bold, beautiful sister servicing Sukuna with such shameless hunger sent a fresh, unexpected pulse of heat through her spent body.
Yorozu pulled off with a wet pop, a smirk on her swollen lips. Then she shifted her attention. She nudged Sukuna’s thigh. “Move. Let me see her.”
Sukuna shifted, just enough. Yorozu dipped her head between Megumi’s splayed thighs. Her touch wasn’t rough, but it was intensely focused, her tongue lapping up the evidence of Megumi’s climax and Sukuna’s possession. Megumi’s back arched off the chaise, a broken, overwhelmed sound escaping her. It was too much, too sensitive, but she didn’t pull away. Her hand found Yorozu’s hair, not pushing, just holding.
Sukuna watched, his own control fraying. Seeing Yorozu between Megumi’s legs, Megumi’s delicate fingers in her sister’s dark hair—it was the most perfect picture he knew. His greed swelled, satiated and yet infinitely hungry for more of this, forever.
He grabbed Yorozu’s shoulder, pulling her up and away from Megumi. He kissed her, tasting himself and Megumi on her tongue. Then he pushed her down, onto her knees by the chaise once more.
“Finish it,” he growled, guiding himself back to her mouth.
This time, he didn’t hold back. He fucked Yorozu’s mouth with the same relentless pace he used everywhere else, one hand tangled in her hair, the other pinning Megumi’s hip to the chaise as he watched her watch them. Megumi’s eyes were glazed, her lips parted, caught between shock and a dawning, profound arousal.
His release was a violent, silent shudder. Yorozu took it all, swallowing greedily, her own body trembling with a secondary, sympathetic thrill. When he finally pulled away, she slumped against the chaise, resting her forehead on Megumi’s thigh, panting.
Silence fell again, deeper this time, thrumming with spent energy. Sukuna collapsed back onto the chaise beside Megumi, pulling her limp body against his side. He reached down, his fingers threading through Yorozu’s hair in a rough, almost affectionate gesture.
The distant, digital chirp of a phone from a pile of discarded clothes sliced through the quiet. A reminder of a world outside the velvet and mirrors. It rang once, twice.
No one moved to answer it.
Sukuna’s hand stilled on Yorozu’s head. “Turn that shit off,” he muttered, his voice thick with satisfaction.
Yorozu just laughed, a breathy, exhausted sound against Megumi’s skin. The phone went to voicemail. The only sound left was their breathing, slowly returning to normal, and the promise, heavy in the air, that this was just a pause. Not an end.
