Makoto crawled to Yuna with a fond smile, then he sniffed at her. "Hmm, but the dog is kind of full already."
He quickly shoved her onto the floor and got on top of her, poking his thick, throbbing cock at her thighs. "But this dog's pee-pee has gotten hard. And it wants to make a puppy instead."
The world shattered into a million pieces of shock for Yuna. One second, she was offering herself up in desperate, humiliating jealousy. The next, she was on her back with the wind knocked out of her and a blindfolded, panting man-dog on top of her.
The sheer absurdity of the situation short-circuited her brain.
"WHA?! GET OFF! GET OFF ME, YOU STUPID PERVERT DOG!" she shrieked in mortified panic. She struggled, her small fists beating against his chest, legs kicking and flailing. "YOU SAID YOU WERE FULL! YOU CAN'T JUST POKE ME WITH THAT THING! IT'S RAPE!"
But even as she screamed, her body betrayed her completely. Hot wetness began blooming between her thighs, a traitorous response to the thick, hard pressure of his cock.
"Oh wow." Ayane hummed appreciatively from the sidelines. She had propped herself up on her elbows, a spectator with the best seat in the house. "Plot twist! The submissive pet reveals he was the alpha all along. Very dramatic! Ten out of ten, would watch again."
Mika, still a satisfied wreck on the floor, managed to lift her head. A slow, analytical smile spread across her face as she watched Yuna's futile struggles. "He's asserting his dominance," she whispered softly. "Establishing the pack hierarchy. The Main Wife must be bred. It's just his natural instinct, Yuna."
Makoto easily shoved his thick cock into Yuna as he ignored her weak pleas. A sharp scream tore from Yuna's throat as he pushed inside. It was pure shock, mixing pain with a deeper violation that her body had secretly been craving.
"It feels good. Woof, woof..." He started howling while thrusting his hips.
"GET OUT! GET OUT! IT HURTS, YOU STUPID DOG! I HATE YOU!" she screeched, her voice cracking with tears. Her nails dug into his shoulders, legs trying to clamp shut and push him out, but she was completely overpowered.
His howling was a bizarre soundtrack to the raw fucking. He thrust into her with a steady, relentless rhythm, ignoring her cries and protests.
Yuna's body, however, was a shameless traitor. Her cunt, already wet with desperate jealousy, grew slicker with every thrust. Her inner walls started clenching around him, not in rejection but in overwhelming pleasure. The protests dissolved into broken sobs and high-pitched moans.
"St-stop... please... ah! No, don't stop... Faster, you fucking mutt...!"
"What's happening to me?" she thought desperately as her body responded. "Why does this feel so good?" Her tsundere brain had completely short-circuited, leaving only the pure need to be claimed, filled, and broken.
"Look at that," Ayane whispered reverently. She was fully sitting up now, a connoisseur watching a masterpiece being created. "Look at her face, she's completely gone. That's the face of a girl who just found out she has a new favorite kink."
Mika pushed herself into a kneeling position with intense fascination. She watched Yuna's hips begin jerking up to meet his thrusts, a small smile touching her lips. "Agree, she looks like a bitch in heat."
Makoto kept grunting and barking. "Woof, woof. I'm going to make... lot of puppies..." He took another bite at the marks on her neck, then shot his hot cum into her.
Yuna's body convulsed under him as his cum flooded her womb. A raw, guttural scream tore from her throat. Her back arched off the floor, nails raking down his back and drawing thin red lines. Her mind went completely blank, a white-hot slate of sensation.
In this moment, she wasn't his stepsister, nor the main wife. She was just a female in heat being bred by the pack's alpha.
She collapsed back onto the floor, boneless and trembling, completely broken. His cum, thick and white, began leaking from between her thighs and pooling on the carpet. The blindfold sat askew on his face. The collar with its cheerful little bell dug into his neck.
The room smelled of sex, sweat, and the faint metallic tang of Yuna's tears.
He collapsed onto her, spent and shuddering. The silence that followed was heavy and profound.
Then Ayane started to applaud. Slow, deliberate, and deeply appreciative. "Bravo," she whispered reverently. "Bravo. That was an interesting game, Makoto."
Mika, ever the serene observer, just nodded. "A perfect end to our game, indeed," she said curiously. She crawled over with fluid grace. She didn't look at him or Yuna. She looked at the pink leash lying forgotten on the floor.
"But now," she whispered, a predatory grin spreading across her face as she picked it up. "The walk begins."
Makoto looked up at her with puppy eyes. "Hey, hey, spare me, Mika. Can't you see I'm too tired to move now?" His eyes sparkled hopefully. "Maybe next time?"
Mika looked down at him, her expression completely unreadable. The serene mask was firmly back in place. His "puppy eyes" slid right off her like water off a duck's back. She gave the leash a small tug. The metal clip clinked softly against the floor.
"Tired?" she said softly, sending a shiver down his spine. "A deal is a deal, Makoto-kun."
She stepped closer, her shadow falling over him and Yuna's spent bodies. "You've got to play your game," she said, too sweetly. "You got your... juice." Her gaze flickered briefly to the mess between Yuna's thighs. "You established dominance and bred the Main Wife."
She kneeled gracefully, movements fluid with quiet power. "But the night isn't over," she purred dangerously as she reached for his collar. "Now it's our turn, our playtime."
"She's really going to do this," he thought with a mixture of dread and excitement.
Ayane chuckled from the sidelines. "She's right, you know," she drawled lazily. "You can't just cum and dash, Makoto. That would be rude."
Mika's fingers were cool and steady as she found the D-ring on his collar. The metal clip snapped into place with a loud, final click. "Don't worry," Mika purred, giving the leash a gentle but authoritative tug. "It's just a short walk. Consider it your... victory lap."
Makoto grunted pathetically as he followed her tug. He kept his eyes on the floor, feeling the humiliation and the weird pleasure it brought. "Geez, fine. But make it quick."
A small, triumphant smile touched Mika's lips. "Of course," she purred condescendingly. "We'll be very gentle."
She tugged the leash gently, and he followed on hands and knees. The rough carpet scratched his palms. The silver bell on his collar jingled humiliatingly with every movement. Mika led him in a slow, deliberate circle around the living room. It was, as promised, a victory lap.
"Just you wait, I will get my revenge." Makoto thought and gritted his teeth. He passed the couch where Ayane had draped herself like a languid cat.
"Aww, look at him," Ayane cooed with mock sympathy. She let her fingers trail through his hair as he passed. "So obedient and well-behaved." She leaned down conspiratorially. "You should have him do tricks. Can you fetch my panties, puppy?"
Mika didn't answer. She just continued the slow, methodical walk, leading him back toward the center of the room, back to the scene of the crime.
