Gripping the delicate fabric of her dress, I ripped it open. The expensive material tore with a satisfying sound, exposing her beautiful body to my hungry gaze.

But...

"Gasp!... you traitor!"

What I saw made me furious.

Underneath her ruined dress, she wore a set of black, lacy lingerie—a bra that barely contained her full breasts, and a thong that did little to hide her glistening folds.

"How could you do this to me!" I whined, pointing at her panties. "I said no panties!"

We had a deal! No panties and she gets to wear clothes but... but...

A deep, guttural growl rumbled in my chest.

She dared. She actually dared to wear panties.

In my horny land.

"Oh, suck it up, you big baby," Vicky shot back, a defiant glint in her eyes. "It’s called lingerie, you barbarian. It’s supposed to be sexy. Not that you’d know anything about that."

"I’ll show you, barbarian," I snarled, my patience completely gone. I grabbed her by the ankles, dragging her to the edge of the bed.

"You want to act like a prude in public? Fine," I said, my voice a low growl. "But in here, with me, you’re mine. My slut. My sister. My whore to breed."

I sat on the bed, pulling her across my lap, her soft ass perfectly positioned. Without warning, I brought my hand down on her exposed cheek with a sharp slap.

SMACK!

"YEEP!" she yelped, more from surprise than pain. "How dare you! Don’t you dare—"

SMACK!

"You. Will. Learn. To. Obey." I said, punctuating each word with another stinging slap to her ass, turning her pale flesh a delightful shade of pink.

SMACK! SMACK! SMACK!

Vicky’s ass jiggled with each impact, the sharp cracks echoing off the temple walls like divine judgment. Her skin bloomed from pink to a fiery red, crisscrossed with the angry imprint of my fingers. Her initial yelps of protest slowly changed, melting into something else. Something... softer.

She started to like it. She didn’t even try to shield her butt with her dragon tail. Vicky took a complete human form, hiding her dragon features.

"Ahh! Morgi, you... fuck! Stop it!" she gasped, twisting in my lap, legs kicking uselessly in the air, but her hips bucked involuntarily, grinding her thong-clad pussy against my thigh. I could feel the heat radiating from her core, the fabric already soaked through.

"Stop treating me like some disobedient—AH!"

SMACK!

"Disobedient what?" I purred, my crimson eyes gleaming with wicked delight as I admired the growing handprints on her rear. "Disobedient little sister? Disobedient cockblocker? Or maybe... my disobedient little slut who secretly loves getting her ass reddened?"

"I do not—MMMPH!" Her protest dissolved into a throaty moan when I delivered a particularly firm smack to the lower curve of her ass, right where it met her thighs. The impact made her thong shift, and I could clearly see the growing wet spot darkening the thin fabric between her legs.

I didn’t stop. My hand kept falling in a steady, punishing rhythm—left cheek, right cheek, both at once—watching with hungry fascination as her ass jiggled and flushed hotter with every strike. Vicky’s breathing grew ragged, her defiant squirming slowly turning into desperate little rocks of her hips against my thigh. Every time my palm connected, a fresh spark of arousal shot straight to my cock, smearing a thick trail of pre-cum across her soft belly.

After a particularly hard series of spanks that left her gasping and trembling, I finally paused, letting my palm rest possessively on her burning cheeks. I squeezed the heated flesh, kneading it roughly, pulling her ass apart just enough for the soaked thong to slip between her slick folds.

"Mmm... look at you," I murmured, voice thick with lust. "Already dripping like a bitch in heat after a few little smacks. You really are my perfect twin."

"Shut... up..." Vicky panted, face buried in the sheets, her crimson eyes glassy with a storm of anger and unwilling pleasure. But even as she tried to sound furious, her ass pushed back against my hand, silently begging for more.

I chuckled darkly and hooked two fingers under the thin string of her thong, yanking it aside with a wet snap. Her glistening, puffy pussy was fully exposed now—swollen, shiny with arousal, and visibly clenching around nothing. A thick strand of her nectar stretched from her entrance to the ruined fabric before breaking.

"Such a pretty cunt," I growled, tracing a single finger along her slick slit from clit to dripping hole. Vicky shivered violently, a broken whimper escaping her lips. "And so fucking wet for your big sister. Were you this soaked the entire time you were scolding everyone about ’decency’ earlier?"

Without waiting for an answer, I slid two long fingers deep inside her in one smooth thrust.

"Aaahhh—!" Vicky’s back arched sharply, her walls clamping down greedily around my invading digits. She was scorching hot and silky inside, her pussy fluttering and sucking me deeper as if it had been starving for this exact treatment.

I began pumping my fingers slowly at first, curling them upward to stroke that sensitive spot I knew would make her see stars. Every thrust was deep and deliberate, my thumb rubbing tight circles against her swollen clit. Vicky moaned louder now, her hips rocking back to meet my hand, her thighs trembling as the pleasure built to an unbearable peak.

"F-fuck... Morgi... you... ahhn... bastard..." she gasped between moans, her voice cracking as I added a third finger, stretching her deliciously. Her juices were dripping down my hand, coating my palm and wrist in shiny trails.

I leaned down, pressing my lips against one of her reddened ass cheeks, kissing the burning skin before sinking my teeth into it in a possessive love-bite. Vicky yelped, her pussy clenching hard around my fingers. I could feel her orgasm approaching—her walls rippling, her clit pulsing under my thumb, her breath coming in sharp, desperate pants.

"Who’s... a little cockblocker now?" I taunted, leaning down to bite her earlobe, my fingers pumping faster, harder, the wet sounds of her arousal filling the room. "Tell me, Vicky. Who’s my disobedient little slut who secretly loves getting her ass reddened and her pussy stuffed?"

"Ahh... I—I... FUCK! I’M CUMMING! I’M CUMMING, MORGI!" she screamed, her body convulsing as the orgasm was approaching, however.

I pulled my fingers out almost completely, leaving just the tips inside, and gave her swollen clit a sharp little flick.

"Not yet," I growled, my voice dripping with dark promise as I watched her pussy clench desperately around nothing, a fresh gush of her juices leaking out. "You don’t get to cum until I say so, Vicky. Until you admit you’re my perfect little slut who wants nothing more than to taste her sister’s cock."

"BASTARD!" she roared in frustration, her body trembling with need, her orgasm hovering just out of reach. "You... you can’t... I’ll never—"

"Oh? Never?"

I thrust my fingers back inside her with brutal force, hitting her G-spot with unerring precision, while simultaneously landing another stinging slap on her already red ass.

SMACK!

"You’re so stubborn, Vicky. Even now, with your pussy soaking my hand and your heart hammering against your ribs like a trapped bird, you try to play the ’civilized’ queen," I purred, my own need a burning ache in my groin, my cock throbbing against her belly. "But I know you. I know you better than anyone. I can feel your body’s truth. And it’s screaming ’YES’."

"I hate you," she hissed, though the words came out breathy and broken. "I hate you so fucking much right now..."

She said, her body betraying her words as her hips bucked back, grinding her dripping cunt against my hand.

"And I love you... You fucking bitch."

"That’s my good girl," I chuckled darkly. "Now, are you ready to be a proper twin and take your sister’s cock like the breeding bitch you are?"

"Only if you stop... ahhh... calling me a bitch," she shot back, a hint of her usual fire returning, though it was dampened by the raw lust radiating from her.

"Hehehe," I laughed, a deep, throaty sound. "I’ll call you whatever I want, Vicky. Now turn over. I want to see your face when I ruin you for anyone else."

She hesitated for a fraction of a second, her defiant gaze meeting mine, but then she slowly, deliberately rolled over onto her back. Her ruined dress was a tangled mess around her waist, her black lacy bra struggling to contain her heaving breasts, the nipples peaked and hard. Her face was flushed, her lips swollen, her crimson eyes hazy with a potent cocktail of anger and desire.

"Happy now?" she asked, her voice a sultry challenge.

"Almost," I purred, my eyes raking over her body. I reached down, hooking my fingers under the cups of her bra and yanking it down, freeing her magnificent breasts. They bounced with the movement, the pale globes a stark contrast to the fiery red of her ass. I took a moment to admire them, my hands cupping their weight, my thumbs brushing over the hard nipples.

"These tits of yours," I murmured, leaning down to drag my tongue across one stiff peak, "were made for sucking and breeding. Just like the rest of you."

Well, this body was made for me in the first place by Lilith, and my succubus wife knows my taste.

"Ahhh!" Vicky gasped, her back arching, her hands tangling in my hair, pulling me closer. "Morgi... please..."

I smiled against her skin, knowing I had her. I positioned myself between her legs, my massive cock nudging against her slick, swollen entrance. I could feel the heat radiating from her core, a silent invitation.

"Look at me," I commanded, my voice a low growl. Her hazy crimson eyes met mine, and I could see the last vestiges of her defiance melting away, replaced by a raw, unadulterated need.

"Beg," I demanded.

Her pride, the dragon pride, warred with her desire, a silent battle playing out across her beautiful face. The defiance flickered, then died, extinguished by the burning need.

"Please," she whispered, her voice a husky plea. "Please, Morgi... fuck me."

"Not good enough," I taunted, rubbing the head of my cock against her clit, making her body tremble. "Tell me what you are."

"Your sister," she gasped. "Your twin... your... your slut."

"And what do you want?" 𝒻𝓇𝑒𝘦𝘸𝑒𝒷𝓃ℴ𝑣𝘦𝑙.𝒸ℴ𝘮

"You," she moaned, her hips bucking up, trying to impale herself on my cock. "I want your cock in me. I want you to fill me. I want... I want you to breed me."

A triumphant grin spread across my face.

"Now that’s what I’m talking about."
