Nui's POV:
Morning sunlight streamed through the window, rousing me from my sleep. Opening my eye, I saw Ragyo lying on top of the bedcovers next to me. I was snuggled up against her, my face nestled against her neck. We were both naked, as usual.
We'd had a busy night. The first half of the night had been spent slaughtering the rebel group that had attacked the mansion. We'd spent the second half the way we spent every night. My pussy was aching for more. I crawled on top of Ragyo so my face was over her cunt, then bent down and started to eat her out.
I felt a hand grip my ass.
"Good morning, Nui."
"Morning, Ragyo-sama."
I felt her clit hardening in my mouth. That turned me on so much. I slipped a hand between my legs and started playing with myself.
"You like my body, don't you, Nui?"
"Yes, Ragyo-sama," I moaned around her clit, "I love your lewd body and your dirty boobs."
I felt her grip on my ass tighten.
"You're calling my breasts dirty?"
"But they are, Ragyo-sama! They're so huge, with such big, lewd areolas. I'm rubbing my clit to them right now."
She lifted her hand and brought it down against my ass with a loud smack. I whimpered in pleasure.
"What a naughty girl you are, Nui. Is that what you usually think about when you masturbate? Your mother's breasts?"
The hand on my ass moved lower. As Ragyo's fingers probed my folds, I clamped my mouth down on her pussy, still rubbing myself with my hand. She stiffened, arching off the bed as she came. I cried out moments later, cumming all over her hand and face.
Ragyo was the first to recover. She rolled me onto my back and climbed on top of me. I felt her wet pubic hairs on my crotch. Her breasts were like a pair of huge pillows squashed against my chest. She positioned herself so her slit was against my thigh and pressed her lips to mine. I responded by thrusting my tongue deep into her mouth.
She started to rock her hips, rubbing her slit against my thigh. She moved with a slow, sensual rhythm. I could feel my thigh grow wetter and wetter as she masturbated against it. Gripping her leg between my own, I started to grind my clit against her. Our movements grew faster as we humped each other to orgasm.
"I'm gonna cum, Ragyo-sama!" I squealed.
"Uh! Uh!" she grunted as she thrust. "That's right! Grind back against me, you nasty girl! Uh! Uh! Uh!"
Ragyo went rigid, groaning loudly. As she shuddered and squirted above me, I reached my own climax, whimpering and clutching the bedsheets.
After a moment's rest, Ragyo turned to the bedroom's double doors with a smirk. "You can come in now, Hoomaru."
I looked at the doors and noticed they were ajar. For a moment there was silence, then the sound of frantically rustling fabric. The doors creaked open. Hoomaru stepped through unsteadily, clothed in a slightly ruffled white business suit. The flush on her cheeks made it clear what she had been doing. She approached the bed and bowed, struggling not to stare.
"G-good morning, Grand Couturier. I am here to report that the rebel leader is awake and in good health."
Ragyo looked at me. "You're interested in the rebel leader?"
I nodded, smiling. "Mm-hm! I was thinking I might use her to convince Satsuki to take a more active role in our games."
Ragyo grinned, running her fingers through my hair. "I love how you think, Nui. That's why you're my favorite daughter."
"Morning, Satsuki-chan!" I called as I entered the dungeon. "Ready to make me feel good?"
I activated the lights with a hand gesture. Satsuki remained silent. Her chin rested against her chest as she hung from her Life Fiber shackles.
I vanished from the doorway and reappeared in front of her. "Are you listening, Satsuki-chan? Huh? Huh? Huh?"
She shifted slightly, her brow furrowing in annoyance. "Go ahead and fuck me, Harime, or get out of here."
"Aw, don't be like that, Satsuki-chan! Every relationship has to have some give-and-take. I can't be pleasuring you all the time. Why don't you make me feel good?"
"Go ahead and kill me if you want to. I'll never obey you."
"I think I have something that might change your mind, Satsuki-chan."
Hoomaru appeared at the doorway, pushing a short, pink-haired girl in front of her. The girl was naked except for the Life Fibers that bound her wrists behind her back.
Satsuki looked up, her eyes widening. "Nonon!"
"S-Satsuki-sama?" the pink-haired girl exclaimed. "I thought Ragyo-sama killed you!"
Satsuki snorted. "She would never be so merciful."
I walked up to Nonon and cupped her crotch. She whimpered and turned her face to the side, her cheeks flushing in humiliation.
"This girl was with the rebels who attacked last night," I said, looking over my shoulder at Satsuki. "We thought you two might like to see each other again."
Satsuki glared at me. "What are you planning, Harime?"
"Hoomaru has a knife with her. She'll kill this girl right now if I tell her to. But if you're a good sister and do what I say, I'll let your friend live."
I nodded at Hoomaru. Hoomaru pressed the knife's tip against the small of Nonon's back. Nonon gasped, then turned terrified eyes toward Satsuki.
"I ... I'm scared, Satsuki-sama," she whispered. "I'm sorry. I know I should be stronger. ... But I don't want to die."
"Don't be ashamed, Nonon," Satsuki said. "No one could expect you to do more than you've already done." She returned her attention to me, her eyes narrowing. "What do you want me to do, Harime?"
Giggling, I snapped my fingers. The Life Fibers released Satsuki, who landed in a heap. I sat on the dungeon floor and spread my legs.
"First, I want you to crawl over here on all fours and make me cum."
I could see Satsuki wrestling with her pride as she got onto her hands and knees. When she reached me, she put her hands on my thighs and gave my pussy a lick.
"Come on, Satsuki-chan. Ragyo-sama's eaten you out so many times; I know you can do better than that."
Satsuki's cheeks burned with shame as she leaned forward. She parted my labia and licked my pussy, then circled my exposed clit.
"That's it, Satsuki-chan!" I said, squirming on the floor. "Don't stop!"
Suddenly I knew I was about to cum. Satsuki's technique was nowhere near as good as Ragyo's, but the thrill I got from humiliating her more than made up for it. I leaned back, putting one hand on the floor behind me and the other behind Satsuki's head.
At last the orgasm hit. I arched off the ground, pressing Satsuki's face firmly against my crotch. As my last spasm died down, I released her head, slumping against the floor.
While Satsuki lay on her face, coughing, I stood up and walked behind her.
"Get back on your hands and knees," I ordered.
Satsuki obeyed, then lifted a hand to wipe my juices from her face.
"Don't wipe your face. I want your friend to see you the way you are now."
Satsuki lowered her hand to the floor. I knelt behind her and started to play with her genitals. I stroked my fingers up and down her cunt. I nuzzled her thighs and teased her clit with my tongue.
Then I pulled back and snapped my fingers. A Life Fiber strand descended from the ceiling and wound itself around Satsuki's clit. It began to buzz, releasing the same vibrations that had driven Ryuko insane a few days ago. Satsuki cried out and collapsed forward, resting her forehead against the floor. Muffled whimpers escaped from her mouth. She looked over her shoulder at me with pleading eyes.
"Please," she whispered. "Please don't..."
My insides nearly melted when I heard those words. Satsuki was actually begging me! I was sure she had never begged anyone for anything before. But here she was, begging me not to humiliate her in front of her underling.
I looked at the pink-haired girl across the room. "Do you hear that? Satsuki-chan is begging me not to make her cum in front of you."
I snapped my fingers again, making the Life Fiber vibrate faster. Satsuki cried out in torment, struggling in vain to hold back her orgasm.
"Come on, Satsuki-chan!" I said sweetly. "Show your friend how hard you can cum!"
Satsuki threw her head back and screamed. Her pussy juice sprayed out, coating the Life Fiber, my legs, and the floor behind us. She kept cumming and cumming as the Life Fiber stimulated her clit. At last, completely spent, she fell forward onto her face, gasping for breath.
I walked over to Nonon Jakuzure, who was staring wide-eyed at Satsuki. She gasped as I shoved a hand between her legs. I worked my finger around a bit, then walked back to Satsuki and showed it to her.
"Look how wet your friend is, Satsuki-chan. She must really like watching you cum." I looked at Nonon. "It's no fair to let Satsuki-chan have all the fun. Come on, Nonon-chan. You two should make each other feel good."
At my command, Nonon and Satsuki licked and sucked each other on the dungeon floor. I watched from a corner, rubbing my clit. Out of pity, I let Hoomaru masturbate too. Afterward I made Satsuki and Nonon clean my crotch with their tongues. Satisfied, I strung Satsuki up with Life Fibers again, in accordance with Ragyo's wishes, and left Nonon with her in the dungeon.
Ryuko's POV:
"Does it feel good, Ryuko-chan?" Nui asked, lifting her face from my breasts.
"Fuck you!"
"That's not very nice, Ryuko-chan. Especially when your little sister's going to so much trouble to make you feel good."
She lowered her head again and lifted one of my breasts to her mouth. She kissed my nipple, then sucked it into her mouth and ran her tongue around it. She moved to my other breast and did the same. She went back and forth, licking and sucking both nipples until they were rock-hard.
I was in Nui's playroom, my wrists held above my head by Life Fibers. I could only stand there as she molested my breasts. Ragyo Kiryuin watched from a chair nearby with a hand between her legs.
"Don't just sit there, Ragyo-sama!" Nui called. "Come play with me!"
"You're such an impatient child!" Ragyo laughed, rising. "Very well. I am Ryuko's mother, after all. It's a mother's duty to comfort her daughter."
Nui moved behind me as Ragyo approached. While Nui fondled my breasts from behind, Ragyo took over where Nui had left off, running her tongue over my nipples.
"My, my," said Ragyo, "I was intending to make your nipples hard, but it seems they're hard already. You must really enjoy having your sister lick your breasts."
Ragyo began making her way down my body. Leaving my breasts, she trailed her tongue over my ribcage and stomach. She licked my pubes and my crotch. She spread my labia with her fingers and thrust her tongue deep inside.
I knew she was intentionally avoiding my clit. I tensed in anticipation every time she neared it, but every time she veered off in another direction. After fucking me with her tongue, she moved lower, licking every inch of my inner thighs. Then she moved back up, spreading my labia again. She licked my exposed pussy from bottom to top, but pulled away just before she reached my clit.
I couldn't take it anymore. As shameful as it was, as low and dirty as it made me feel, I needed to feel her tongue on my clit.
Maybe ... maybe if I move my hips a little, she won't notice...
When her tongue neared my clit again, I shifted ever so slightly, trying to get some contact. But she was too quick for me, pulling her tongue away before it touched my clit. She went back to my thighs, licking and kissing, then started sucking on my slit below my clitoris. By this point, I was beyond caring. Whimpering in frustration, I moved my hips this way and that, trying to rub my clit against her tongue.
"What's wrong?" she taunted. "Why do you keep moving your hips? Is there somewhere you want me to lick?"
"Sh-shut up! I'm only like this because you're controlling my nerves with your Life Fibers!"
"What are you talking about, Ryuko? I'm not using the Life Fiber resonance at all right now."
"You're lying!"
Smirking, Ragyo leaned forward and sucked my clit into her mouth. She held it in her mouth like a tiny popsicle, flicking it with her tongue. I spasmed, cumming hard. She clamped her mouth over my pussy and held it there while I writhed and bucked.
As my orgasm died down, she pulled her face away. "You taste just like Satsuki."
I opened my eyes and glared at her. "You piece of shit. What kind of pervert rapes her own daughters?"
Ragyo met my hateful glare with a smile. "Maybe the same kind of pervert who gets off on her own mother's tongue."
"F-fuck you!"
Ragyo stepped back, and Nui snapped her fingers. Countless Life Fibers descended from the ceiling, twining themselves into cords. They wrapped around my arms and legs and lifted me into the air. I gritted my teeth and turned my face to the side as one of the cords probed my inner thighs.
"I made it extra thick this time, Ryuko-chan!" Nui called. "I know how big you like them."
The thick cord began to penetrate me. I was so wet that it slid in smoothly, but I still gasped at how wide it was stretching me. At last the cord halted, pulsing deep inside. Each pulse sent electricity shooting through the nerves of my cunt.
The cord started to move, slowly at first. Each thrust forced muffled whimpers from my mouth. As the thrusting picked up speed, my whimpers turned into moans and screams. I felt my body begin to tense.
"Look, Nui," Ragyo said. "Your sister is about to cum."
"Is that true, Ryuko-chan?" Nui called. "Are you about to cum? Are you about to cum all over that big, fat cock?"
I arched my back in the air, letting out one long scream. Waves of agonized pleasure ran up and down my body as my juices squirted out around the fat cord. The Life Fibers didn't slow down. They kept thrusting even after my orgasm subsided.
"P-please ..." I pleaded. "... I just came ..."
The Life Fibers were deaf to my pleas. I felt the cord in my pussy increase in thickness as it fucked me even harder. Before I knew it, another orgasm was building inside me, and it was going to be huge. I threw my head back and came with a long, sobbing cry. Still the Life Fibers kept fucking me.
My eyes fluttered open for a moment, and I saw a lone strand of Life Fiber descending from the ceiling. It wrapped around my clit and started to vibrate with a high-pitched whine. I screamed.
I heard Nui's laugh over the whine of the Life Fiber. "What a nasty face. You must be in ecstasy, Ryuko-chan."
I came within seconds, screaming at the top of my lungs. The Life Fiber granted me no relief, continuing to buzz against my sensitive clit. When I managed to open my eyes, I saw two more Life Fiber strands descending toward my crotch.
"No, stop!" I shouted, twisting my body in a futile attempt to escape.
One strand joined its companion around my clit. The other pressed against the very tip of my clit, vibrating cruelly. Meanwhile, Nui walked behind Ragyo. She ran a hand down Ragyo's stomach as my screams filled the room.
"Mmmm, Ragyo-sama, Ryuko-chan looks like she's having so much fun."
I was screaming continuously now, no longer caring how loud I was. My face flipped from side to side as I shrieked.
Oh god, I'm going to cum again!
The Life Fibers kept vibrating against my clit as spasm after spasm wracked my body. Just when I thought I had finished cumming, I felt yet another orgasm building.
I lost count of how many times I came. After what seemed like ages, the Life Fibers pulled away from my crotch. Still wrapped around my limbs, they lowered me to the floor. I dimly heard the playroom door creak open.
"Nighty-night, Ryuko-chan," Nui called sweetly.
I don't know how long I lay there. When I opened my eyes, it was night. I was facing the window that overlooked the courtyard. This time there was no moonlight. Clouds blotted out the sky, leaving the world in pitch blackness. I rested my cheek against the floor and wept.
Someone ... please ... help me...
