"HMMM!!" The Doberman's muffled scream vibrated through the dildo gag, his eyes widened in a mix of terror and fascination as he beheld the transformation of my body.
My muscles shifted and grew, taking on a more bestial form, while my skin rippled and changed to pure, silver fur. My fingers elongated into sharp claws, and my teeth sharpened into fangs that glistened with saliva. The most striking change, however, was the massive, canine cock that jutted proudly from my hips, thick and pulsating with veins, and knot.
"Aw, what's the matter, pup?" I purred, my voice low and dripping with menace. "Never seen a real wolf cock before? Or are you just scared it's gonna split that slutty little ass of yours in half?"
I grabbed my new pink wolf cock, stroking it slowly, letting him see the sheer size of it—veined, glistening, and impossibly thick. Pre-cum beaded at the pointy tip, dripping onto the floor with a soft plap. His nostrils flared, catching the musky scent of my arousal, and I saw his pathetic cock twitch again, still locked in my mana's cruel grip, unable to spill.
"Look at you, dripping like a bitch in heat," I mocked, stepping closer, letting the head of my cock brush against his thigh. "You're practically begging for it."
"HMM!!... HMM," the pup whined, a strange mix of fear and anticipation shining in his eyes, however, his reaction only fueled my arousal, making the pre-cum drip faster, painting his thigh with my slick.
"Hehehe" I grinned.
I couldn't resist that pleading look, the way he whimpered and writhed, knowing his fate was sealed. So I did the most rational thing, I crouched behind him, seizing his hips with bruising force, my claws digging into his fur. His ass was still gaping from my arm, slick and quivering, practically winking at me.
"Fuck, this hole is begging for a proper knot," I growled, spitting on it again, watching the saliva mix with the slick mess already coating his entrance. "Let's see if a dog like you can handle a wolf."
"HNGH—!" His muffled cry was desperate as I pressed the tapered tip of my cock against his hole, teasing it with slow, deliberate circles. His muscles clenched instinctively, but I wasn't in the mood for games. With a low snarl, I thrust forward, sinking the first few inches into his tight ass with a loud, wet schlop.
"Ah...fuck..." I moaned, leaning my head back as his anal ring—already back to being tight—stretched around my thick, canine cock. My hips bucked on instinct, filling his ass even more with my size, watching the way his hole stretched to accommodate me and his walls hugged my cock like they were made for it.
"This ass was built for fucking, wasn't it? Bet you've been dreaming of a real alpha claiming you like this." I leaned over him, my swollen belly brushing his back as I sank deeper, the knot at the base of my shaft kissing his stretched rim. My claws flexed against his hips, drawing pinpricks of crimson blood. His eyes rolled back, drool spilling from his mouth, his own pathetic cock still twitching uselessly, denied the pleasure of release.
It was the best feeling, the complete subjugation of a formerly prideful and self-assured dog. My dominance over him, and my complete ownership of his ass was unmatched, and the slickness of his hole, the eager way his body gave way to mine, only drove my own arousal higher.
I was starting to see why people were so into BDSM. This power thing really did something for me. I could definitely get used to it.
"MM-MMMM—" the dog cried, tears streaming down his cheeks as I hilted in him, bottoming out with a growl of pleasure. His walls squeezed and rippled around me as if trying to milk me.
"Relax, pup," I whispered, my voice a low, dominant growl. "Let your master in. Let me fill you up, claim you, and make you mine."
PAT! PAT! PAT!
I began to move, my hips rolling in a steady, rhythmic motion. Each thrust was deep and powerful, driving my cock further into his tight ass. The sound of our bodies slapping together filled the room, it was a good call to place a sound barrier around V or she would never focus on her training.
"Yes, take it. Take it deep," I growled, reveling in the slick friction, the tightness of his hole, the feel of my balls slapping against his, my knot kissing his rim, threatening to barge in. It was primal, carnal, and fucking delicious.
"HMM~" His muffled moans grew louder, more desperate. I could feel his body responding, his muscles clenching around my cock, urging me deeper. I smiled a cruel, satisfied smile, knowing that I was giving him exactly what he needed.
"Fuck, this ass is perfect," I groaned, my head tilting back as waves of pleasure coursed through me. "So tight, so eager. You're gonna be my personal slut, aren't you? Gonna keep this hole ready for me whenever I want it."
Yes... I have decided to ask Lora to leave this Doberman here in my land, I took a liking to his first-class anus, and with a little modification on my part, he will be perfect. A needy, submissive ass to use when I want.
PAT! PAT! PAT!
I picked up the pace, my thrusts growing feral, each one driving my knot closer to breaching his rim. Each time he let out a high-pitched whimper that drove me closer to my peak. Wrong! I was at my peak.
"Time to knot you, bitch," I snarled, my voice thick with lust. With one brutal thrust, I forced my knot past his rim, the thick bulb popping inside with a wet schlop.
The Doberman's entire body seized as my knot lodged inside him, his back arching violently, his muffled scream tearing through the room. His ass clamped down on me like a vice, muscles fluttering in desperate, involuntary spasms as his body tried—and failed—to reject the intrusion.
'Too late for that, pup.'
Swiftly my knot expanded inside him, stretching him obscenely wide, locking us together, preparing for the breaking of the dam.
"AHHH!.....Cumming!!!"
Like a tidal wave, a thick, scalding stream of canine-futa seed blasted into his guts, filling him completely. I could feel his body convulsing, his muscles milking my cock for every last drop of my seed.
"There you go, pup," I panted, my voice a low, satisfied growl. "Take it all. Take every fucking drop of your master's seed."
His body shuddered and jerked as I continued to pump my load into him, the intensity of it making his eyes roll back, his limbs twitching spasmodically. The knot sealed every drop inside, ensuring his body had no choice but to take it all, to be marked and claimed in the most fucked up way. For him at least.
I leaned down, nuzzling his neck. My claws dug into his right shoulder and side, drawing fresh beads of crimson that glistened against his dark fur, the scent of blood and arousal mingling in the air. His pathetic cock twitched uselessly, still locked in my mana's cruel grip, leaking a steady stream of pre-cum that pooled beneath him on the floor.
"Good boy," I whispered, my voice a low, dominant purr. "You took your master's knot like a champ. You're mine now, completely and utterly mine."
My long tongue flicked out, lapping at the sweat and tears on his neck, tasting the salt of his submission.
"Mmm, you taste like a whore," I purred, nipping his ear with my fangs, drawing a fresh, high-pitched whine. "And it's fucking delicious."
"!!!" He shook, attempting to crawl away when I dropped my whole weight on him, but sadly for him, in this horny world, there was no escape from me.
"Oh, you're not going anywhere, pup," I mocked, my voice dripping with sadistic delight. "This knot's keeping us tied until I'm done with you—and trust me, I'm nowhere near done."
Swiftly I flipped him over to lie on his back, and let me tell you, the sight of a massive pregnant-like belly filled with my hot cream, on a male dog-kin, was simply fucking glorious, a masterpiece of depraved art, a real turn-on that caused me to squirt from my wolf-pussy.
"Fuck, look at you," I purred, my voice a low, dominant growl. "That belly stuffed with my seed, jiggling like you're pregnant with my pups. You're a proper slut now, aren't you?"
"Ahh~... this is hot" I ran my claws lightly over the taut curve of his abdomen, feeling the heat of my cum inside him, the faint slosh of it as I pressed down.
"Let me give you a reward for the amazing first-class ass, bitch" I said, licking my lips, seizing the pathetic penis of his, and using my authority as the administrator of the Nightmare Tower, I channeled my magic giving him one hell of a reward.
"HNGH—!" His muffled scream was a mix of pain and ecstasy as his cock began to transform, growing under my grip. The small, twitching length swelled, veins pulsing as it stretched into a massive, 14-inch canine dick, thick and glistening, complete with a bulbous knot at the base. His balls grew heavier, swelling to match, hanging low and full.
"HHMMMM!!!"
He came in a thunderous, bucking arc. White-hot spurts coated his chest and abs, splattering his chin and face. But he didn't care. His eyes were locked on his new cock, and as he was about to touch it—
SNAP!
I snapped my fingers, causing the cock to vanish in a burst of smoke, revealing the real gift beneath. A fully fledged pink vagina.
"HAHAHAHA" I let out an amused laugh at the dog's reaction, something he had wished for his entire life had just become a reality, but before he got a taste of what it really means to have a big dick, that dream was ripped apart.
"A cock is useless to you, bitch"
