Chapter 12: Dominating Her Brother’s Women

Note: This story was commissioned by Ultrasound 7 and has allowed me to share it with you. This may contain scenarios and acts that I normally wouldn’t write. There will be a strong sex slave/domination theme. I will keep this from violating any cannon established in the world and I developed the mythology that drives this story.

Pyrriah – Rathay Desert

“Nephi?” I asked as I rode on my camel out across the salt flats before the sphinx’s cave.

“Yes, Mistress Pyrriah?” the sphinx asked. She padded along beside us in her lion-like form. She looked so interesting in it, her body all tawny fur save for her head and chest (and breasts) which were human. She had a mane of dark-red hair and gray-feathered eagle wings. Sphinxes were all born out of Las’s seed, like my family.

“You called me Gewin’s get,” I said. “What did you mean by that?”

“Are you not one of the War God’s daughters?” the sphinx asked. “Did you not know you are a demigoddess?”

“I am a demigoddess,” I said. “But I am not Gewin’s daughter. I’m Las’s. I’m Kurtis’s twin sister.” This unease clenched about my body. I had strange abilities. I could make fire in extreme circumstances, my hair glowed when I was angry or in the throes of climax, and I knew how to fight with a tulwar even though I had never seen a sword. “Right, Mother? I’m your daughter with Las.”

“She is my daughter,” said my dragon-mother. “I carried her and Kurtis in my womb for nine months. The only god I had been with was Las. I have never met, let alone lain, with Gewin.”

The sphinx looked perplexed. “My apologies, Mistress Pyrriah. I grew up in the cave. I have never left it. I must be mistaken. I thought I sensed Gewin in you. There is something ... peculiar about you. You are different from your siblings. Las’s scent is all over them. They brim with lust.”

“I brim with lust,” I protested. “I’m just as kinky as Lasla and Kurtis.” I glanced at my brother riding his camel at the lead of the party. “Right?”

“She’s a kinky one all right,” Kurtis said. He glanced back at me. “She’s never shy about sucking cock or licking cum out of pussies or anything. If I asked her to strip naked and fuck a dildo in and out of her cunt before the entire city, she would.”

My pussy clenched. “That sounds hot. Can I do that?”

“Yes, yes, can we?” Lasla asked, quivering. “We could make Mother Azuliana lick our cunts, too.”

Kurtis laughed. “See, they are Las’s daughters. Just like you are, Nephi. We’re all family here.”

“I must be Las’s daughter because that was such a sexy thing to hear.” Nephi fluttered her wings. “And you truly bred me, Master Kurtis? I carry our incestuous child in my womb?”

“Yes, you do.”

That made me so wet. I had to be Las’s daughter. We all had powers. Lasla could make sex toys, Kurtis could manipulate lusts and desires in others, and I could make fire and fight. There had to be some way that was connected to Las.

There just had to be.

Lasla

After we had our camp readied for the night and the sun had set, I knew what I had to do. I had to make sure that Nephi knew how to please my brother. She was part of our party, his newest sex slave. She had to be prepared to love him in any way.

“Nephi!” I commanded, my voice cracking.

“Yes, Mistress Lasla?” Nephi asked. She padded over to me in her sphinx form. She had such a leonine grace in it.

“It’s good that you come when called,” I said. “You are Kurtis’s. Obedience is paramount.”

“Of course,” she said, her tail swishing back and forth. “He tamed me. His will is my will now.” She smiled, sharp teeth gleaming between her plump lips.

“Good. You also have to know how to please him sexually. You need to learn to give him a proper blowjob.”

“Proper blowjob, huh?” Kurtis said, rising from the fire we had made. Yes, you had to make fires in the desert. How else did you cook your dinner? It also drove back the dark. He unwound his blue robes and slid them off his muscular body. His cock thrust out hard before him.

He was always hard. That was one of the things that made him so sexy.

“Know, get your head down there and suck,” I commanded, my own pussy hot. I slipped out of my purple robes, letting them fall off my body. My round breasts jiggled. “And mind those teeth. You don’t want to damage his cock.”

“Never,” said Nephi.

She folded her wings tight about her body. Then she lowered herself down to her belly, her boobs jiggled as she brought her lips right to his cock. She opened her mouth wide. Then she slid her lips over his dick. He groaned as she did.

Then she sucked. So she knew that much. He groaned, his face contorting from the pleasure of her suckling mouth. My pussy clenched, the heat building and building in my cunt. I wanted to touch myself, but I held back.

“Now, are you using your tongue?” I asked.

Nephi shook her head.

“Well, use it. Swirl it around over his dick. You have to increase his pleasure. You have to make him cum. Whether you get any of his cum is just a bonus.”

She whimpered and moved her head. Her wings fluttered. Kurtis groaned, a smile spreading on his lips. I could tell my brother was enjoying it. My pussy clenched, so glad that the sphinx was pleasing him.

Her sucking and slurping filled the air. Pyrriah and Mother Azuliana were kissing by the fire, the pair lost to their lesbian incest. They provided the background noise to the hot sight of my brother getting blown by the monster.

“Now move your head,” I said, pushing on the back of her head. I slid her lips a few inches down his cock. “Come on, work that head. I want him firing his cum into your mouth. Do it. Make him cum.”

She whimpered and her tail swished. She bobbed her head. He groaned louder. His face twisted in delight. I loved it. The sphinx worked her head up and down his cock, sucking the entire time. Drool ran down her chin.

I swiped it up and held it on my finger before her eyes. “See that spittle. That’s yours. Every blowjob should be sloppy like this. You’re doing good.”

She moaned in delight.

“Now you can purr,” I said. “Do it. Purr. The sound will hum around his cock and make him feel real good.”

The sphinx’s purring rose through the night. Nephi’s wings twitched more. This was so exciting. My cunt clenched, my pussy on fire with lust. I trembled, my face contorting with the bliss of this moment. It was incredible.

“That’s it,” I groaned, my pussy dripping juices down my thighs. “Yes, yes, just like that. You’re doing great.”

“Yes, you are,” panted Kurtis. “You are giving an amazing blowjob.”

Nephi purred louder. Her eyes closed. She made such obscene sounds as she sucked on him. She nursed with hunger. She worked on that cock. She pleasured him with her passion. That made me so hot. I loved it.

I watched her blowing him. Saw the pleasure on his face. In the background, Pyrriah and Mother Azuliana sixty-nined, devouring the other’s pussy. My own cunt was on fire, but I ignored it. I was having too much fun.

“That’s good,” I told Nephi. “But now you really have to please him. You have to deep-throat him.”

I straddled her body, grabbed her head from behind, and thrust her mouth down his cock. I felt his dick hit the back of her throat. Her wings fluttered, brushing my legs. I kept pushing on her head. She gurgled.

“Swallow all of his cock,” I moaned. “Relax that throat and let him in!”

I pushed harder. The wicked sounds she made had more cunt juices flowing down my thighs. Then she slid her mouth down his dick. I shuddered, pushing her head forward, sliding her lips down and down his thighs.

Her lips pressed into his bush.

She had taken every inch of him. This rush surged through me. I groaned, my cunt clenching. Wicked heat rushed through me. My hips wiggled back and forth, my twat on fire. This was so hot to do. To teach her this.

“Gods damn, that’s good,” Kurtis moaned. “You are a good teacher, Lasla.”

I beamed at my brother.

I drew back Nephi’s head. She sucked and slurped the entire way. Such a sloppy sounding blowjob. I pulled back until his cock popped out of her throat. Then I pushed on her again. She moaned and then swallowed his cock faster this time.

“That’s it,” I cooed, fucking her mouth up and down his cock. “That’s how you deep-throat him.”

I released her head and she kept doing it on her own. I moved to the side now, watching. Kurtis groaned, his face contorted in bliss. I smiled at the sight. The sphinx deep-throated his cock again and again. She swallowed his shaft with hunger.

With a growl, he grabbed Nephi’s head and held her in place. He fucked his cock in and out of her compliant mouth. She purred, wings flexing. Her powerful body could stop this. She was strong than my brother and me.

But she didn’t. She submitted to him.

“That’s right,” I cooed. “He’s mouth-fucking you. Mmm, it’s something you have to be ready for. And you’re doing amazing at it. Look at you go. Just swallowing his cock as he fucks you. Mmm, yes, yes, just like that, slut.”

Nephi purred her delight while Kurtis growled. His orgasm built and built. He panted, his chest rising and falling as he thrust forward. He fucked hard into her mouth. He drove his cock down her gullet.

He fucked her hard, his balls cracking into her chin. And she accepted his passion. Her purring moans around his dick were so intoxicating to witness. I swooned, so happy that I could help Kurtis enjoy his sphinx better.

It was fun being like the mistress of his slaves. Controlling them and the women in his lives. I shuddered, my cunt clenching. I would be the best mistress and sculpt them to please him in so many wonderful and kinky ways.

I almost orgasmed just thinking about it.

“Las’s big dick!” Kurtis growled and buried to the hilt in her gullet. “Yes!”

He pumped his cum straight into Nephi’s belly, denying her the pleasure of tasting his cum. But that was his prerogative. He pumped jizz down her gullet. He grunted with each blast. I shuddered, my pussy on fire from the wicked sight.

Then he finished. He pulled his cock out of her mouth. More drool spilled down her chin. She panted, her big breasts rising and falling as she stared up at him. She licked her lips, her wings rustling.

“Now thank him,” I said. “Thank him for dumping his cum into your belly.”

“Thank you, Master,” she moaned. “I’m so happy that my mouth and throat could make you happy. Thank you for cumming down my gullet and into my belly!”

“You’re welcome,” he said and grinned at me. I made my brother happy.

I almost came again.

Kurtis

Lasla lay on her back now as Nephi shifted to her human form. The fur melted away. Her lion-like limbs became sleek thighs and sultry arms. In moments, a beautiful woman knelt before me. She still had her cat ears twitching as they thrust up through her hair.

“Eat her cunt now,” I ordered Nephi. “Devour my sister’s pussy.”

“Yes, yes, get that tongue in me and make me cum,” Lasla ordered. “As you do, part your butt-cheeks. You have to take my brother’s dick in all of your holes.”

“Yes, Mistress Lasla.” As Nephi lowered her face to my sister’s cunt, she reached behind and parted her butt-cheeks. Her asshole winked at me above her furred muff. “Please, please use my asshole, Mater.”

My dick throbbed at the sight and her words. I grinned and fell to my knees. “I will gladly use your asshole, Nephi.”

Her purrs rumbled from her throat. She buried her face into my sister’s twat and licked her. Lasla shuddered, her face contorting with the delight. I grinned, so glad that she was getting the pleasure she deserved.

My dick throbbed as I sank to my knees. My cock bobbed out before me. It swayed, my balls hard and aching. They were full of cum that I would unleash. Just fire spurt after spurt of cum that would baste her asshole.

I was so ready for that. I pressed my cock into her butt-cheeks and slid down to her asshole. She moaned her, cat ears twitching. I loved the sight as I pushed my dick right against that anal ring. Her tight hole resisted.

“Relax your asshole,” groaned Lasla. “Just let him slide into you.”

“Yes, Mistress,” she moaned.

The resistance from her asshole lessened. Then she groaned as her anal ring parted. I smiled as her hot flesh slid over my dick’s crown. Nephi’s wonderful bowels held such promise. I was so eager to slide into her.

I popped into her bowels. I groaned as her hot flesh slid over me. She felt incredible. I enjoyed that delight as I slid my cock deeper and deeper into her bowels. I gripped her hips, her asshole stretching to take my dick.

“Master!” she moaned. “Oh, Master, thank you for using me.”

“Yes, yes, use her,” Lasla moaned. “Ooh, Nephi, lick all over my pussy with that naughty tongue of yours.”

“Yes, Mistress.”

Nephi’s head moved as she lapped at Lasla’s cunt. My sister shuddered. She whimpered, her face bursting with pleasure. I groaned, too, my cock bottoming out in Nephi’s asshole. Her velvety sheath gripped every inch of my dick.

It was an incredible delight. I savored it. I smiled at the feel of that wonderful asshole squeezing about my cock. I shuddered and drew back. My cock throbbed in her depths. She massaged me, purring as she devoured my sister’s cunt.

I plunged back into Nephi. My balls smacked into her taint. She groaned, tightening her bowels on my dick as I pulled back. That was perfect. Just a delight to enjoy. I groaned, loving every heartbeat of fucking her asshole. I pounded the sphinx.

I thrust my dick hard into Nephi’s asshole. I reveled in the feel of her velvety bowels around my cock. She made me feel amazing. I groaned, loving every second of thrusting into her bowels. That hot, tight, delicious asshole clenched about my cock. It was stunning to feel.

Amazing.

“Yes, yes, yes!” I groaned, thrusting to the hilt in her. I plunged my cock hard and fast. I buried to the hilt in her with passion. I thrust with all the strength that I had. It was incredible to feel her around me. “Nephi!”

“Master! Master!” she purred. “I’m so glad I’m making you feel good.”

“So good,” I growled, gripping my sphinx’s hips. I owned her. What a heady thrill to experience. This wonderful rush of bliss. I thrust with power into her bowels. I fucked her hard and fast. I buried to the hilt in her. God, it was incredible. “Fuck, yes!”

I plunged away in her. I fucked her with hard strokes. Powerful strokes. She purred into Lasla’s cunt. My sister shuddered, her boobs jiggling. Her black hair fanned out over the blanket she lay on. She arched her back, the silvery moonlight kissing her tits.

“That’s nice, Nephi, but you can do better!” she groaned, grabbing the sphinx’s mane of dark-red hair.

“Better?” gasped Nephi in dismay, her asshole clenching about my cock.

“Mmm, don’t just lap at my entire pussy. Vary your tongue’s strokes. Focus on parts of me. Nibble on my labia. My clit. Suck on the bud. Thrust your tongue into my depths. And don’t be afraid to use your fingers. To plunge one or two or even three into me. You can fuck them out of me while sucking on my clit.”

“I can do that, Mistress Lasla!”

I loved how eager she was to please. She was such a delightful creature. I thrust harder into her asshole, my balls smacking into her taint. The pleasure rushed through me. It was fantastic to enjoy. I buried into her. I fucked her with passion. I drove my dick into her hard and fast. I slammed my cock to the hilt in her wonderful bowels. She squeezed when I pulled back, increasing my pleasure.

She shifted her hand. Lasla gasped as Nephi pumped her arm to thrust her digits in and out of my sister’s cunt. I smiled, so glad she was teaching Nephi to be a better lover. The sphinx moved her head as she feasted on my sister’s cunt.

“Yes, yes, yes!” I moaned, savoring burying into her bowels. “Please her, Nephi. Make my sister cum!”

“She’s definitely doing that!” moaned Lasla.

“I’m so happy!” purred Nephi. “Master, I will. I’ll make your sister cum. And you, too. My asshole will make your dick spurt all that hot cum into me.”

“I know!” I groaned, thrusting hard and fast into her. I buried into her anal depths with such force. Her asshole felt incredible about my cock. I loved the feel. I savored the bliss. This was amazing to experience. I groaned, thrusting faster and harder. I buried to the hilt in her. I pumped away at her bowels with everything I had.

The pleasure melted through me. It was fantastic. I loved every second of it. I savored the bliss of fucking her asshole. I groaned, my dick plowing deep and hard into her bowels. I fucked her with strength. With vigor.

I slammed into her depths. I buried to the hilt in her over and over again. My dick buried deep into her. Hard. It was fantastic to feel. Amazing. My cock throbbed in her asshole. I savored the feel of her while watching my sister writhe on the ground.

“Yes, yes, yes!” Nephi moaned. “Las’s big dick, Master, that’s good. That’s amazing. I love being fucked in the ass by you.”

“And how do you feel about fingering my cunt?” asked Lasla.

“I love fingering your cunt and licking your cunt and lapping at your cunt!” moaned Nephi. “I love all of this. I have masturbated so many times dreaming of doing naughty things. Now I get to. I love you, Master, for naming me!”

“You’re welcome,” I groaned as I pumped away at her asshole. I fucked her with passion, letting her feel just how much she meant to me. “you can cum. I want to feel that ass spasming around my dick.”

“After you make me cum!” Lasla groaned. “Then you can cum on my brother’s cock and satisfy him with your dick.”

I grinned at my sister. “You are a wicked one.”

She winked at me.

I thrust over and over into Nephi’s asshole. It was an incredible hole to enjoy. I loved the feel of her bowels squeezing about my dick, that velvety grip massaging me. My balls tighten. She would make me explode. I would pump all my cum into her asshole.

My sister moaned louder, gripping Nephi’s hair. The sphinx still thrust her fingers in and out of my sister’s cunt. Still pleasured her. This was such a treat to enjoy. I loved every second of thrusting into her. Fucking her hard.

My dick melted in her asshole. I loved every second of it. I buried into her depths again and again. Lasla moaned. Her face twisted. She arched her back, her silver-painted tits jiggling, moon shadows dancing over her flesh.

“Las’s big dick, yes!” squealed my sister. “Drink my cream! Oh, drink it!”

“Yes, Mistress!” Nephi purred.

She drank my sister’s cunt cream. I drove into my sphinx’s asshole. She purred louder. Then her bowels spasmed around me. I groaned at that massaging grip. I drew back my cock and savored her sheath rippling around me. She felt incredible. my balls tightened.

“Gods, yes!”

I spurted my cum into her bowels. I fired blast after blast of my jizz into her convulsing asshole. The sphinx milked me with her rippling flesh. The pleasure slammed into my mind. My grunts joined her purrs and my sister’s gasps.

“Yes, yes, Nephi!” Lasla moaned. “Gods damn, that’s how you eat pussy! Mmm, yes, yes!”

“That ass!” I groaned. “Nephi, that is a delicious ass you have.”

“Thank you, Master, for cumming in it!” she gasped, her passion echoing through the air. “I am so happy to pleasure you. It is my dream to give you such bliss.”

I shuddered through my pleasure. I hit the peak of my ecstasy. I quivered there, loving every minute of it. I groaned, savoring the delight of this moment. It was incredible. I shuddered, my mind melting beneath the bliss.

Then I fired the last of my cum into her bowels. I panted, savoring that wonderful bliss. My mind felt dizzy from the euphoria that burned through me. It was incredible to feel it flowing through me. I smiled, so glad to experience it.

Lasla – Shilter Strait

The trip back from the desert was uneventful. The Treasure Box was waiting for us. The morning after we returned to Goldport, we sailed out to sea and began rounding the southern coast of the Rathay desert. On the second day, we entered the Shilter Strait and soon were passing by the territory of the Queendom of Naith.

We would be in Ankush on the next day.

That night, we anchored in the middle of the strait. I wanted to have more fun being in charge.

“Okay, ladies!” I said. “Line up! All the women on the crew of the treasure box.”
