Chapter 1: Princess on a Leash
The air in Sukuna’s bedroom was thick, a mix of spilled whiskey, melted wax, and the clean, scared sweat rolling down Megumi’s spine. She knelt on the cold mahogany floor, her knees pressing into a discarded silk scarf. The only thing she wore was a collar of deep red velvet, the buckle cool against her throat.
Shadows from a dozen half-burned candles licked up the walls, making the black drapes seem to breathe. Sukuna circled her, his footsteps silent on the deep rug. He was already hard, his fat cock jutting out as he palmed himself lazily, watching her. The look in his dark eyes wasn’t just hunger; it was ownership, pure and simple.
“Look at her, Yoru,” he said, his voice a low rumble. “Our pretty little thing is shaking.”
Yorozu stepped from the gloom, a smirk playing on her lips. She was naked, her curves painted gold by the candlelight. She moved with a shameless confidence that made Megumi’s stomach flutter with a confusing mix of awe and dread. Yorozu’s fingers, tipped with sharp black polish, came to rest under Megumi’s chin, tilting her face up.
“She’s always shaking. It’s part of her charm.” Yorozu’s thumb brushed Megumi’s lower lip. “Aren’t you, Gumi? Nervous little rabbit.”
Megumi tried to answer, but all that came out was a soft, choked sound. She could only nod, her wide eyes darting from Yorozu’s knowing gaze to Sukuna’s predatory stare.
“She knows what tonight is,” Sukuna said. He stopped behind her, his presence radiating heat. He didn’t touch her, not yet. “Don’t you, princess?”
“I… I think so, Kuna-nii,” Megumi whispered. Her hands fluttered in her lap, unsure where to rest.
“You think?” Yorozu laughed, a bright, cruel sound. She let her hand drop from Megumi’s face and instead cupped one of her small breasts, her touch firm. Megumi gasped, a jolt going straight to her core. “After all our talks? After you watched me and nii-chan last week? You think?”
Megumi’s blush was immediate, heating her face and chest. She had watched. Hidden behind the screen door, her hand pressed to her mouth, as Yorozu rode their brother, her head thrown back in ecstasy. The memory alone made her damp.
“I know,” Megumi corrected, her voice slightly stronger. “It’s… it’s my night.”
“Good girl.” Sukuna’s praise was a warm breath against her ear. Finally, he touched her, his big hands settling on her bare shoulders. His thumbs stroked the sharp lines of her collarbones. “Your night to be the center of everything. Our beautiful, shared thing.”
Yorozu leaned in, her full breasts brushing Megumi’s arm. “Your night to stop thinking so much,” she murmured, her lips now at Megumi’s other ear. “To just feel what we give you. What we all give each other.”
Megumi whimpered as Yorozu’s mouth found the sensitive spot beneath her jaw. At the same time, Sukuna’s hands slid down her arms, guiding them behind her back. The shift in position arched her spine, thrusting her small chest forward. Yorozu took immediate advantage, lowering her head to take a tight nipple into her mouth.
The dual sensation was overwhelming. The soft, sucking pull of Yorozu’s mouth, the sharp tease of her teeth. The hard, possessive grip of Sukuna’s hands as he deftly tied her wrists together with another silk scarf. Megumi’s head fell back against Sukuna’s stomach, her breathing turning ragged.
“See? She loves it,” Yorozu said, pulling away with a wet pop. She looked up at Sukuna, her eyes glinting. “She’s dripping already and we’ve barely started. Such a greedy slut, just like us. She just needed permission.”
“She has it,” Sukuna said. His voice had gone rough. He looked down at Megumi, her eyes glazed, lips parted. “My perfect princess. You belong to us. Tonight, you learn what that really means.”
He moved then, walking around to face her. He fisted his cock, giving it a few slow, obscene strokes. Megumi’s gaze was locked on it, a mixture of fear and fascination tightening her throat. It was so big, intimidating. She’d seen it, yes, but never so close, never with the intent of it being inside her.
“Open,” Sukuna commanded, not unkindly.
Megumi obeyed, her mouth falling open. A thin string of saliva connected her lips. He stepped forward, the broad head of his cock resting against her lips.
“Not there, you impatient bastard,” Yorozu chided, swatting his hip. She was on her knees now beside Megumi, one hand stroking her sister’s thigh. “The plan was me first. I get her warmed up. You get the main event.”
Sukuna’s mouth twisted into a smirk. “Since when do you follow plans?”
“Since I want to taste her before you ruin her for the night,” Yorozu shot back. Her hand slipped between Megumi’s thighs, and her smirk turned triumphant at the wetness she found. “See? Mine.”
Sukuna laughed, a short, dark sound, but he took a step back, yielding. “Fine. Get her ready for me.”
Yorozu didn’t need telling twice. She pushed Megumi gently onto her back, her bound arms making her awkward, vulnerable. Yorozu loomed over her, her dark hair a curtain that blocked out the rest of the room. “Just look at me, Gumi,” she cooed, her tone shifting from teasing to something dangerously tender. “Just at your Nee-chan.”
Megumi nodded, her breaths coming in short pants. Yorozu kissed her then, not like a sister, but like a lover—deep, consuming, her tongue exploring Megumi’s mouth with a possessive familiarity. Megumi moaned into the kiss, her body softening despite its binds. This, she knew. Yorozu’s kisses were a familiar sin, a gateway drug.
Yorozu broke the kiss, trailing her mouth down Megumi’s throat, over her collar, between her breasts. She took her time, licking and nipping, her hands spreading Megumi’s thighs wide. Megumi cried out when Yorozu’s tongue finally found her clit, a hot, relentless point of pressure that made her hips jerk off the floor.
“That’s it,” Sukuna murmured from somewhere above. He was watching, his hand moving steadily on himself. “Let her make you feel good.”
And she did. Yorozu ate her out with a shameless, enthusiastic expertise, her fingers joining her tongue, working Megumi open. The world narrowed to the flickering candles, the scent of her own arousal, and the relentless, building pressure coiling in her belly. She was babbling, “Nee-chan, please, Yoru-nee, I’m—“
“Come for me,” Yorozu growled against her, the vibration tipping her over the edge.
Megumi shattered, a silent scream on her lips as her body convulsed. Waves of pleasure, sharper and brighter than any she’d managed alone, crashed through her. Yorozu gentled her, licking her through the trembling aftershocks until Megumi whimpered from over-sensitivity.
Only then did Yorozu sit up, wiping her glistening chin with the back of her hand. She looked utterly pleased with herself. “Ready for you, Kuna. She’s nice and loose.”
Sukuna moved like a predator finally allowed to feed. He hauled Megumi up by her bound arms, turning her onto her knees again. He positioned himself behind her, his hands gripping her hips hard enough to bruise. The blunt, hot head of his cock pressed against her, and Megumi froze, the earlier pleasure momentarily swallowed by a spike of sheer panic.
“Sukuna,” Yorozu said, her voice losing its edge for a second. She was watching Megumi’s face. “Easy.”
“Shh, princess,” Sukuna breathed into Megumi’s ear, ignoring Yorozu. He nuzzled her neck, his voice dropping to a hypnotic murmur. “This is what you want. This is where you belong. With me. With us. You’re ours.”
The words, the possessive mantra, did something to her. The panic receded, replaced by a deep, aching emptiness that begged to be filled. She gave a small, frantic nod.
He pushed in.
It was a burning, stretching fullness that stole her breath. She cried out, a raw, broken sound. Sukuna held still, letting her adjust, his own breath shuddering. “Fuck,” he gritted out. “So tight. My perfect girl.”
He began to move, slow, deep strokes that gradually soothed the burn and stoked a new, deeper fire. Megumi’s cries melted into low moans. Yorozu crawled in front of her, capturing her messy kisses, her hands roaming Megumi’s body, pinching her nipples, stroking her clit in time with Sukuna’s thrusts.
“Look at you,” Yorozu whispered, her eyes blazing with pride and lust. “Look at our sweet, dirty girl taking her brother’s cock so well. You’re one of us now, Gumi. Really one of us.”
The approval in her voice, the sheer carnal reality of the moment, broke something final inside Megumi. The last fragment of resistance dissolved. She was theirs. This was her belonging. She met Sukuna’s thrusts, tentatively at first, then with growing urgency.
The rhythm became frantic, a three-beat syncopation of skin, sweat, and gasped breaths. Sukuna’s grunts grew louder, his hands bruising her hips. Yorozu’s fingers worked Megumi faster, pushing her toward another cliff.
“Come with me, princess,” Sukuna commanded, his voice ragged. “Now.”
It was the command that did it. Megumi’s second orgasm ripped through her, violent and blinding, her inner walls clamping around him. With a roar, Sukuna followed her over, pumping his release deep inside her with several final, jerking thrusts.
For a long moment, the only sounds were their ragged breaths and the faint hiss of a dying candle. Sukuna slumped over her, his weight pressing her into the silks. Yorozu rested her forehead against Megumi’s, her smile soft, almost genuine.
Slowly, Sukuna pulled out. He untied the scarf around Megumi’s wrists with surprising gentleness, rubbing the marks left behind. Megumi collapsed forward, caught by Yorozu, who guided her head to rest on her lap. Sukuna sat back on his heels, watching them, a satisfied, dark gleam in his eyes.
Yorozu stroked Megumi’s hair. “You did so good,” she murmured.
Megumi, boneless and drifting, just nuzzled closer. The shame was there, a quiet, cold whisper in the back of her mind, but it was drowned out by the warmth of Yorozu’s skin, the solid presence of Sukuna nearby, and the profound, horrifying sense of being home.
Sukuna reached for his whiskey glass on the nightstand, took a long swallow, and looked at the two women tangled together on the floor.
“Tomorrow,” he said, his voice already thick with new intention, “we start on the rest of the rules. And we talk about those other little fantasies you wrote in that journal, Megumi.”
Megumi’s eyes, which had begun to drift shut, flew open. A fresh, different kind of tremor went through her. He’d found it. He’d read it. The secrets she’d never dared voice were now his to use.
Yorozu’s smile widened, showing teeth. She kissed the top of Megumi’s head. “See?” she whispered, thrilled. “The fun’s just starting.”
