Both harems had gathered at Emerald Hil Zone. The true harem master would be decided in the place where Sonic and Tails began their adventures together. The girls watched intently as hedgehog and fox approached one another. After some soul searching, they'd both realized that their girls were right. Only one of them could be the alpha male, the king of both harems. And each of them were determined that it would be them. Sonic smirked. "Right little bro, we'll keep it simple... First to pin the other wins all the marbles?" he asked. Tails nodded. "Sounds fair." he said. It did not sound fair. Sonic had the clear advantage. However, when Kosmo and Silver counted down to start, Tails acted fast. As Sonic came at him, the fox twirled his tails and flew above him, dropping on top of the confused hedgehog! This didn't topple Sonic right away, he tried to shake Tails off as he clung to his back. Tails felt Sonic begin to fall backward, intending to pin the fox under him! Extending his tails, he stopped their fall, and used his tails to push off in the other direction, sending Sonic face down onto the ground with Tails on top! Sonic struggled to break free, only to find himself turned onto his back and securely pinned by Tails! "Looks like I win, Sonic... LITTLE bro!" he winked, sticking out his tongue.

It was then that, pinned under Tails, Sonic felt that strange sensation resulting from the vaccine he was tricked into taking some time ago. His body glowed, and Tails watched as he underwent an incredible transformation. Sonic's hips widened, his waist seemed to slim down... Soon the hedgehog had a cute hourglass figure, but that wasn't all. Tails felt something push against his chest as he pinned Sonic. Blushing, he saw that the blue blur had boobs now! Sonic gasped, HER voice now high pitched and girly! Tails began to wag his namesake as the implications of what was happening sank in. "Ohhh... I've won more than I dreamed! Sonic... Looks like you're about to join my harem, too...sis!" he grinned. Sonic looked up at him in humiliation, and it didn't help that the girls were watching, and seemed to be enjoying this...even Amy. She felt defeated, and even if she wanted to cling to pride and run away, she felt a weird notion in her mind... Like this was Tails's victory, and it would be wrong to deprive him of it. Why was she thinking that? Was she...feeling attracted to Tails? She gasped softly as the fox cupped her lovely new breasts. "B-bro...wh-what are you gonna do?" she asked nervously, blushing. Tails rose over her to reveal his hard, hungering cock. "I'm gonna make you mine, Sonic... That way we'll never have to fight again..." he winked. Shivering, Sonic didn't struggle. She could see his point. But...could she really let herself become Tails's harem slut?

This was quite the victory for Tails. The fox was planning to enjoy it quite a bit. He kissed Sonic square on the lips, his tongue darting into her mouth as she groaned a bit, wriggling under her nervously. She could feel his cock poke her belly. "Shit...he's big!" she thought, blushing. As the kiss broke, Tails rubbed his cock against her entrance, purring softly. "Sonic, your body's so soft...so lovely..." he cooed, prodding his tip against her folds, "Ready to become mine?" he whispered. Sonic shivered and gasped. "T-tails... D-don't!" she whimpered. Then, she felt him push into her folds. Her eyes went wide. "Aaaahh!! Oh n-noo!" she gasped. He felt amazing. That was why she reacted this way... there was no way she could resist becoming his slut at this rate! Tails gasped as he sank into Sonic's depths. This was different from the other girls he'd been with. Sonic's pussy felt so warm, so inviting. He held her under him and began to thrust, enjoying her submissive moans as her walls hugged and massaged his dick! Sonic could see his tails happily wagging as her best friend fucked her. "Ahhh...oh chaos...n-nooo...this can't be..." she panted, gripping the ground as her body was giving in to the pleasure. The fox leaned down to lick the hedgehog's breasts, purring as his tongue swirled around her tits. He could feel Sonic's will to resist was nearly gone. She was even starting to move her hips along with him. "I'll take good care of your harem, Sonic...and you, too. You'll get plenty of love with me..." he purred, his cock pounding away at her pussy roughly as she moaned in defeat. "Ohhh... damn you, Tails... y-you really beat me!" she cried, finally admitting defeat. With that, Tails was able to happily enjoy fucking her in this position for a bit...until he decided to change things up. Soon, Sonic was on her hands and knees like a...well, like a fox. Tails then began to tease her ass. "I'm not gonna get you pregnant, Sonic... yet." he purred, slowly pushing into her tight rear. Sonic grunted in a bit of pain, glancing back at him. "P-pregnant??" she whimpered, "M-master...please be gentle..." she shivered. Tails stroked her quills with a smile. "Oooh, master...I like it..." he grinned. He started out gently at Sonic's request, his cock slowly pushing deep into her anal tunnel. Tails also reached around to fondle her soft breasts. "Just think, Sonic... one day you'll feed our pups with these..." he cooed, giving them a squeeze. Sonic blushed and gasped. Was this maybe too far? She let out a protestful groan, only to feel him start to speed up his thrusts. "Aaahh... M-master... D-do you love me?" she squeaked submissively. Tails blushed, and looked around at their audience of harem girls. He chuckled softly. "Sonic... of course I do... I love you and all my girls..." he said, winking at those watching. Even Amy blushed at this. Tails then nuzzled into Sonic's neck and kissed her, continuing to thrust into her ass as she moaned. Sonic looked more submissive by the moment, and Tails was loving it. "Ahhh... aaaahhh... T-taillsss!! F-fuck me! I-I'm yours, Tails!!" she cried. Hearing this, the fox hugged the hedgehog tightly and thrusted his cock deep into her rear, moaning as he neared his peak. He nuzzle her head as he felt himself getting close. "That's right...ahhh...you're mine!!" he murred, and then cried out as he came, pumping his cum into Sonic's rear until it leaked onto the floor! Sonic gasped and moaned, her ears drooping as she felt at last that she truly belonged to Tails. Her former harem approached as well, looking quite eager. "Do us next!" said Amy, licking her lips. Tails smirked to himself. He was the alpha dog now.


Over a year passed. Tails had needed to build a bigger home to accomodate his growing family. Up in the bedroom, everyone was gathered. Even Cream, who was busy breastfeeding Skye Prower, Tails's first born son. Beside her was Cosmo with their daughter, Melody, also suckling her mommy's teat. Vanilla was feeding a new brother that Tails had given Cream. Wave was bottle feeding a little feathered fox, and Kosmo was breastfeeding young Starr Prower. There was Shade with an echidna-fox suckling her teat, Blaze with a cat-fox getting her milk, and Silver with a young hedge-fox getting bottle fed. Sonic laid on the bed, her eyes settled on Amy. Amy was holding Rosie Prower, the middle child, and quite a scamp, trying to suckle both her moms tits at once. Sonic gasped, not out of any form of regret, but because Tails was balls deep in her pussy. "Ahhh...hmmm... Our family is so full...but not complete yet... Ready to carry my last baby, Sonic?" Tails purred. Sonic gasped and blushed, shivering. "Manik...or Sonia... we'll call it..." she panted, "Ohhh, Tails... thanks for beating me..." she moaned, her eyes rolling back as she approached orgasm. Tails chuckle and leaned in to kiss her. "I love you Sonic...you big subby sissy!" he teased. Then, his cum flowed into her, his seed seeking out her eggs within her womb. They'd use both names...for the twins Sonic was to give birth to...

The End!
