Lasla – Ankush, the Queendom of Naith

My brother and sister had won!

They had beat Tharaka and Solja, her troll brother. Kurtis and Pyrriah had prevailed, and our entire family was riding the high of their success. They had passed the Trial of Steel. Only one more to go. The Trial of Pain. That one made me nervous, but...

They had won!

I was still too giddy to really worried about it right now. We were back in Princess Lavhi’s quarters. The rakshasa-slave lay on her side, quivering from the pleasure my dildo buzzing away in her pussy gave her. I controlled that golden toy, giving her or denying her the pleasure she craved. That she had been addicted to.

Pleasure was a far, far better motivator than pain.

“Come and lick my pussy, slave,” I moaned the moment I sank onto some of the pillows on the floor. My legs were spread wide, my cunt on fire. I stared at Princess Naryu, our other rakshasa-slave. We didn’t have to break her mind to pleasure like we did her cousin. “I want to feel that tiger tongue on my cunt.”

“Yes, Mistress Lasla.”

The princess’s brown face blurred. Whiskers and fur sprouted. Her mouth became a muzzle tipped by a wet, black nose. Slits formed as her eyes became a feline grin. Orange fur, striped like a tiger, with a white ruff at the throat and bottom of the jaw.

Purring, the rakshasa-slave nuzzled in to feast upon my pussy. I shiver ran through me as the whiskers caressed my thighs. A shudder raced through my body. This was perfect. My back arched as the power I had over her swelled in me. Thanks to pleasure, the princess had been turned into a slave.

The monster into a pet.

Those powerful jaws and those sharp fangs could rip me to pieces. Instead, they nuzzled into my cunt and licked me. I groaned, my back arching. I shuddered at how amazing this felt. My toes curled, savoring the pleasure of her tongue sliding up my slit. The roughness of it was incredible.

She brushed my clit. Sparks burst from it. My shoulders squirmed against the ground. My heart pounded in my chest. My toes curled as I loved the feel of her tongue licking up and down my pussy. My round breasts quivered.

“Las’s big dick,” I moaned, crying out to my divine father kept imprisoned by Throwia. We were supposed to save him, but the world was so distracting.

We kept getting side-tracked.

Now this Test of—

“Yes!” I squealed as that rough tongue licked me again.

I shivered through the wonderful bliss that swept over my arm pussy. My clit burst with sparks. The pleasure showered over me. I groaned and gasped, my face scrunching up. This heat rushed through me. I tossed my head, loving every second of it. Every last moment of her hot tongue lapping at my cunt.

Her tongue stroked through my flesh. She caressed me with hunger. She made me gasp and moan my delight. Her whiskers tickled my thighs as her every lick brought me towards that wonderful peak. Her tongue slid into my cunt.

“Oh, Gods, yes!” I moaned, bucking.

“Mmm, your mouth looks so inviting,” Kurtis said, kneeling beside me. His cock thrust at me. I could smell the sour aroma of Princess Naryu’s asshole on it. “Would you mind?”

“No!” I moaned. “I love you, Kurtis. I’m always happy to clean my brother’s dick.”

He smiled at me, his eyes so blue and piercing. Like my eyes.

His cock pressed past my lips. I groaned at the sour musk, that earthy flavor of the rakshasa’s asshole. I quivered in delight as her tongue swirled around inside of my cunt, so rough against my flesh. So stimulating.

I moaned around my brother’s dick. I sucked hard on him, my cheeks hollowing as I enjoyed the taste of his cock. It was stimulating. Incredible. An outstanding delight. I groaned around my brother’s dick, sucking him clean.

“Gods damn, that’s good,” my brother groaned.

He had won!

Joy swept through me as I kept remembering that. It was such a heady fact. It swept such wonder through me. I groaned, my body trembling as I suckled and nursed on my brother. The pleasure swept through my body as the rakshasa kept licking and lapping at me.

Her tongue slid out of my pussy and brushed my clit. I squealed around my brother’s cock. He groaned, his face twisting in pleasure. I could tell that I was pleasing him. That was a good thing. My tongue danced around his cock, wanting to give him such delight. Such passion. He would have such an amazing cum.

“That’s it, sister,” he groaned. “Mmm, slave, are you pleasing my sister.”

“Of course, Master,” purred the princess. “I am giving her my all.”

“Good,” my brother panted. “I want her moaning around my cock. I want her swallowing every drop of my cum.”

“She shall, sir,” purred the princess.

Her tongue licked faster at my cunt. It felt incredible. I groaned and squirmed. Then Princess Naryu’s hands shot up my body and grabbed my tits. She squeezed my round mounds. She kneaded them as she feasted on my cunt.

Pleasure spilled through my body. This heady bliss swept through me. It was such a treat. A wonderful delight that had me quivering in delight. My face scrunched up before the bliss of this moment.

My orgasm built faster and faster. I suckled on my brother’s cock with all my might. I nursed on him, eager to have his cum flooding my mouth. I would gulp it all down. I would swallow every drop of his spunk. It would be incredible. A true delight to enjoy. My tongue danced around his cock. I swirled about him.

“Yes, yes, yes!” he groaned. “That’s it. That’s fucking it.” His face twisted, such delight burning on his features. “Gods damn, Lasla!”

Such joy surged through me. I buffed the tip of his cock clean and gave him pleasure. I was so close to cumming. Just moments away from that magical delight exploding in my cunt. I would have a huge orgasm on the rakshasa-slave’s tongue.

Princess Naryu’s tongue stroked up my slit. She brushed my clit. I gasped, bursting at the joy of it. My face twisted. I groaned, sucking hard on my brother’s cock. He groaned, too, his dick throbbing in my mouth. His salty precum stained my lips, overpowering the lingering traces of sour asshole.

The rakshasa-slave licked again. She brushed my clit.

I exploded.

I squealed around my brother’s big dick, sucking hard. Waves of delight washed through my body and splashed over my mind. I drowned in them. They swirled over my thoughts as I squealed through my rapture. I trembled there, sucking hard on my brother’s cock.

“Las’s big dick!” he growled.

His cum erupted. Hot jizz pumped into my mouth. I gulped down my brother’s incestuous seed as I rode the tide of bliss rushing through my body. The rakshasa-slave licked up my pussy cream like a good kitty cat. Spunk poured hot down my throat as I squealed out my delight.

I savored the wonderful delight pouring down to my belly. I drank it all down as I quivered through my orgasm. I hit the peak of my pleasure, my thighs squeezing about the rakshasa-slave’s head. Her tongue rasped over my pussy, sending one last flutter of delight through me. I had drained my brother dry.

I slid my mouth off of him and panted. “Oh, that was delicious.”

“Gods, it always is when you suck me off, Lasla,” Kurtis said.

I beamed up at him. They had won!


Pyrriah

The nagging worry about the Trial of Pain kneaded my mind, but that was tomorrow’s problem. Lasla would probably have to help Kurtis prepare for that. Domination was more her thing than mine. She enjoyed playing the mistress.

I just liked having sex.

Still, Kurtis and I had prevailed. My training had paid off. He hadn’t been killed by Tharaka. In fact, he had defeated her. As he proffered his cock to our sister’s mouth, I was feeling that itch to have fun.

I glanced over at my dragon-mother. She had her chastity belt off. Kurtis had removed it during the celebration in the gladiator suite and had never replaced it. Lasla was sucking on Kurtis’s cock, and I felt that urge to do some fellating of my own.

And there was only one other cock I could suck. My mother’s.

“Mmm, Mother,” I purred, sliding my arm around her and cupping her breast from the other side. “Want to have some fun.”

“You know I am always ready to please my children, Mistress Pyrriah,” she cooed. “How shall I pleasure you.”

“Let’s sixty-nine,” I purred. It was a term we had come up with for giving oral pleasure to each other. “Mmm, how does that sound?”

“It sounds delightful,” my dragon-mother purred, her blue hair swaying about her shoulders. “Who shall be on top?”

“Me,” I purred. It made sucking a dick, even a clit-dick, easier.

Mother smiled and then sank to the floor. She had such large breasts. They were big and soft and formed into a pair of jiggling mounts. She spread her legs, her hairless pussy on display. I licked my lips as I stared at her clit peeking out of her folds.

That would soon be filling up my mouth.

I straddled her face, lowering my fiery bush to my mother’s waiting lips. She grabbed my thighs, pulling me down to her with greedy hunger. It was clear my mother was eager to pleasure me. Just wanting to lick my cunt.

The moment my curls rustled over her face and my pussy lips kissed her mouth, she licked. I groaned as her tongue dug through my folds. I leaned over her, staring at her clit as she lapped over me. Her tongue caressed labia, driving me wild.

My boobs pressed into her stomach while her nipples grazed against my belly. I went straight for her clit, her sweet scent filling my nose. I kissed her bare cuntlips and latched onto her clit. I sucked hard on my mother.

“Ooh, Pyrriah,” she moaned and fluttered her tongue up and down my clit. “Do you want...?”

I suckled harder.

“Naughty girl,” she moaned and then her clit blossomed into my mouth.

I nursed on my mother’s growing cock, loving how she filled up my mouth. I opened my lips wider and wider to take her increasing girth. My tongue stroked along the crown, feeling her spongy tip developing into the crown of a cock. Then came the first salty flavor of her precum.

An incestuous thrill ran through me.

I nursed on her cock. I loved her big dick that filled my mouth. Kurtis’s was bigger, but our mother came close. I squirmed on her, grinding my cunt into her mouth as I savored every moment of this pleasure building in me.

I would have such a wonderful orgasm. It would be outstanding.

She licked and lapped at my cunt. Her tongue fluttered up and down my folds, driving me wild. I groaned, my heart pounding in my chest as my mother’s tongue thrust into my pussy folds. I squealed around her clit-dick.

I worshiped her girl-cock.

My mouth bobbed up and down her hermaphrodite-dick. I savored sucking on her. I nursed on her with passion. My tongue danced around her clit-dick, loving the way her precum spilled over my tongue. I danced around her, savoring the flavor of her precum.

“Oh, yes, yes, Mistress Pyrriah,” Mother moaned, her fingers digging into my ass.

Mistress Pyrriah...

I slid my mouth off her cock with a wet plop. Drool ran over her tongue. “Mother, just call me Pyrriah or daughter right now.”

“Yes ... daughter.” She nuzzled her lips into my pussy, my curls rustling over her mouth. “Mmm, you’re such a loving daughter to suck on your mother’s cock.”

“Maybe I’ll even finger your pussy,” I purred.

“I might finger your asshole.”

“Wonderful,” I groaned and then swallowed her cock again.

I nursed on her while her tongue fluttered up and down my folds. Her hand slid over my ass, her fingers dipping into my crack. I shuddered as my hand found her shaved pussy. I stroked her pussy lips as she found my little asshole.

We teased each other, her digits dancing over my dirty hole, my fingers sliding up and down her cuntlips. I nursed on her clit-dick, her precum spilling into my mouth as I enjoyed every bit of her tongue stroking my labia while her finger caressed my asshole in slow circles.

Then her finger pressed on my sphincter.

I groaned as my anal ring widened to take her digit. She wiggled into my velvety bowels. My pussy clenched. I groaned as the heat melted own to my pussy being so deliciously licked by my mother’s wicked tongue.

I had to return the favor.

I thrust two of my digits into her pussy, into the hole that birthed Kurtis and me. Her hermaphrodite-cock throbbed in my mouth. The flavor of her precum grew in strength. It was this wonderful delight.

I suckled on her with such happy delight. I nursed with passion on her, my cheeks hollowing as I bobbed my head. I slid my lips up and down her flesh. Her pussy clamped down on my digits. She moaned into my snatch, her tongue fluttering around my clit.

She pumped her finger in and out of my asshole. She thrust it in deep and wiggled it about in me. I groaned, savoring the delight. Pleasure rushed over me. I shuddered, squirming my twat against her mouth. Her tongue caressed up and down my pussy folds.

This was such a delicious treat. I groaned around her cock, my orgasm building and building.

“Oh, yes, yes, my daughter has such naughty fingers and a wonderful mouth,” Mother moaned into my cunt.

A pleased thrill rushed through me. My hair pulsed red with my fiery passion.

I sucked harder on my mother’s cock. My flickering hair flowed around me, my passion building and building as she worked her finger in and out of my asshole. That naughty delight had me nursing with passion on her hermaphrodite-dick while my fingers plundered her cunt.

Her silky flesh gripped my digits. She moaned into my cunt, her tongue thrusting into my depths. She swirled around in me, her finger fucking in and out of my asshole. I was hurtling towards my orgasm. Just towards that big burst of pleasure that would have me gasping out in rapture.

Mother danced her tongue about in my pussy, teasing me. I moaned on her cock, my drool running down her shaft other hairless folds. Her cunt clenched down my digits thrusting into her depths. Her toes curled.

I brought her closer and closer to cumming. Closer and closer to flooding my mouth with all her salty cum. I would gulp it all down. Just drink down all that wonderful spunk. It would be just the best thing in the world.

“Oh, Pyrriah,” my mother moaned, her finger wiggling about in my asshole. “You’re going to make me cum!”

I whimpered my delight around her cock, her precum growing saltier and saltier.

I thrust my fingers faster in and out of her cunt. Her pussy clamped down, her flesh so hot about my digits. My hair glowed brighter, my orgasm hurtling closer and closer to bursting through me. My mother licked my clit.

Then she sucked on it.

My hair flared bright. I burst with rapture.

I squealed around my mother’s girl-dick. I jammed fingers deep into her cunt as juices flooded out of my pussy and bathed her mouth. My asshole convulsed around her digit. Pleasure rushed through my body. I bucked on her, sucking hard on her hermaphrodite-cock.

“Oh, yes, yes,” she moaned. “Gods, that’s good. Matar’s big dick and juicy cunt!”

Hot cum erupted into my mouth.

I reveled in the delight of her hermaphrodite-spunk flooding my mouth. It was such a wonderful treat. I gulped it down. I swallowed down her jizz, the salty delight setting my taste buds alight. My hair burned so bright as we shared in our incestuous passion.

I quivered through the bliss. I reveled in the delight. I gulped down load after load of her cum. I swallowed it all. It flowed down to my belly and warmed me up. This was such a delight to share this pleasure with her while my mind drowned in bliss.

Wonderful, buzzing, amazing bliss.

This was so sweet because we had won. My brother and I had defeated them. No, my brother had defeated Tharaka and Solja. Despite my superior swordsmanship, Kurtis had led the day. He had tamed Tharaka to his will and used her to convince her brother to surrender.

Kurtis was amazing.

And I was born to fight at his side.

I slid my mouth off my mother’s cock. I swallowed the cum and then rolled off of her. I stared down at her, my body shuddering. She smiled at me, her lips smeared in pussy juices. She stretched her arms over her head, her clit-dick throbbing.

“Oh, Pyrriah, daughter, that was amazing,” she groaned.

“What am I, Mother?” I asked. “Why am I so different from the others.”

“You’re my daughter,” she said, smiling. “What else matters?”

“That’s not—”

A loud knock wrapped the door. A loud one that echoed through the room. Everyone snapped their heads over there. Kurtis, with Lasla and princess Naryu, rose. Then he marched towards it looking so strong.

I rose to join him.


Kurtis

“Open it, Nephi,” I said to my sphinx guarding the door. So often these days she had to stand by while the rest of us had our fun.

Pyrriah came up beside me as Nephi opened the door, her large breasts swaying. On the other side was a Naithan woman with a sly smile on her lips. She had long, wavy hair that fell down her back. A silver chain ran from the piercing on her nostril to an earring on her left lobe. It swayed against her brown cheek.

“Yes?” I frowned. “You’re Pradu, right? The slave master.”

“What are you doing here?” Lasla demanded, her voice full of disgust. I vaguely remembered Lasla going to meet with Pradu to learn some techniques about being a mistress and came back in a huff.

“I am here to offer congratulations on your victory, Noble Kurtis,” she said, her smile broad but there was something oily about it. She glanced over at Nephi and then at the other slaves in the room. My mother rose, her cock having vanished.

Pradu walked past me without a concern in the world. Not a leave to enter. She looked down at Princess Lavhi and, with her slippered foot, pushed the slave over until she lay on her back. The slaver shook her head, her wavy hair dancing around her head.

“Is she good for anything now?” she asked with a sneer to her tone. She was unafraid of being alone in my room surrounded by us. “Besides moaning like a whore.”

“Take away her pleasure, and she is very eager to do whatever we want,” Lasla said. “Otherwise, she’s quite docile.”

“Interesting,” said Pradu, arching an eyebrow. “And Princess Naryu, I hear you are ... more intact.”

“They didn’t break me like my cousin,” said Princess Naryu. “What are you doing here, cousin?”

“My, you let the whore speak,” Pradu said, turning to me.

“Cousin?” I asked.

“I am looking forward to seeing what you are made of in the Trial of Pain,” she said, staring at me. “Mmm, I cannot wait to see you on your knees.”

I felt her desires. She liked to inflict pain. It was the only way she could find her climax. If she wasn’t hearing screams, she couldn’t even get wet. She was barely aroused right now. What little she felt was the possibility of torment to come.

“How do you know about it?” I demanded. “Who is she, Princess Naryu?”

“Princess?” Pradu laughed in mocking derision. “You call your slave ‘princess’ like she’s not a whore wearing your collar.”

“I call her by what she is,” I growled, anger in her. “She’s a princess and my slave. It pleases me to remind her of it and myself.”

“Mmm, there’s that fire from the arena,” said Pradu, smiling. “You can tell him who I am, slave.” “I am telling him who you are because he commanded it, slut,” Princess Naryu snapped back. “She’s my mother’s favorite slave trainer. My cousin, Pradu.”

“Is she a rakshasa or is she related to you by your father?” I asked.

“Can any human be as arrogant as this cunt?” Princess Naryu said.
