Sonic and Tails were forced to meet by their respective harems, intending to settle once and for all who was the most worthy to rule the harems. A funny thing happened on the way to the meeting place, though... Well, fateful might be the more appropriate word.

Tails was walking alone through the jungle area of the Mystic Ruins. His girls were supposed to meet him near Big's place before leaving. Why? Something to do with fried fish. Someone certainly wanted some. However, as he walked towards the meeting place, he heard a strange sound. It was getting louder as he was getting closer. Was it...moaning? Tails froze. "Sonic... you didn't...!" As he said this aloud, the moaning stopped. Then, in front of him, Shadow the Hedgehog appeared in a flash! "No, he didn't... I did!" he smirked before swiftly knocking the fox down!

When Tails opened his eyes, something felt off. It was a familiar feeling. He slid his hand up to rub his head, but on the way brushed against something on his chest. A breast. Eyes shooting open, Tails saw that he was a girl, as Bucky had once transformed him! Standing nearby was Shadow, and behind him... the harem. Vanilla, Wave, Cosmo and Kosmo sat nearby, all looking rather dazed, a look of lust in their eyes. Shadow smirked. "Thought you'd keep all these bitches for yourself? Well, they're my bitches now..." he said, stroking his hard dick as he stood over Tails. The vixen shivered, starting to remember. Some memories from during the GeneXXX Wave incident had faded, but she could recall...Shadow fucked her before. "W-wait, Shadow! You don't have to do this! I-it was an open harem..." Tails said weakly. Shadow smirked. "Oh? That why you and Sonic were about to have a grudge match?" he asked. "I-it wasn't gonna go like that..." Tails tried to say, but Shadow didn't care. He grabbed Tails's head, lifting her to her knees. "...You're mine now, fox..." he said darkly.

Tails found Shadow's thick dick thrusted in her face. She gasped. It was amazing. Clearly bigger than his as a male. She couldn't help feeling a bit of shame about that. Shadow held her head and smirked. "Lube me up...or don't, at your own risk..." he said. Tails shivered. There was really no way out of this, was there? She extended her tongue, looking quite nervous. She licked along his length, gasping at how long he was. Then, in a moment, Shadow forced himself into her mouth, pushing his cock back and forth over her tongue inside her maw! Tails yelped and groaned, trying not to choke on him as she obediently licked his dick. It didn't take long for Shadow to free her from this humiliating scenario. "Okay... That's enough lube... Now, to break you!" he announced with a smirk.

Tails was soon on her back, her legs lifted over Shadow's shoulders as his huge cock prodded her entrance. He had an evil grin on his face. "I'm gonna knock up both harems...including you..." he murred. The vixen gasped, then yelped as she felt his cock thrusted into her roughly! Tails shivered nervously. "Y-you... N-no!! Don't get me pregnant!!" she gasped. Shadow held up her legs and started to pound her pussy, ignoring her pleas. He grinned, watching her breasts jiggle from his motions. "You're still so tight, Tails... It drives me wild!" he smirked. Tails pounded at the dirt, trying to claw herself away, but it was no use. She gasped and panted, blushing as his thrusts started to feel good. "N-nooo... Sh-shadow!!" she cried. Shadow kept her legs over his shoulders, and brought his hands down beside her chest. From this position, as he stared her in the face, he slammed deeper and deeper into the vixen's pussy. Tails looked up in fear, gasping and panting with his every thrust. She gripped his arms, but ceased to struggle. He was beginning to break her. "Mmm, liking it yet, babe? You're all mine..." Shadow murred, moving back to allow her legs to fall at his sides, and then seizing her body, his hands grasping her soft melons while his lips pressed up to hers! Tails tried to shout in protest, but instead got his tongue in her mouth. She started to moan as his thrusts, his gropes and his kiss drove her body wild. It was becoming harder to resist. Soon, she'd be all his. As the kiss broke, Shadow was pleased to hear Tails continue to moan. He picked up his pace, thrusting hard and deep into the fox, seeking to find her fertile womb. "I'm gonna knock you up...and I'm gonna fuck you in front of Cream regularly... And fuck Cream in front of you..." he vowed. Tails yelped, but didn't stop moaning. Her body wanted it so bad. How could she deny her body? "Sh-Sh-Shadoooow!! U-uhhhnnn... I...I..." she stammered, shivering. Shadow licked her breasts a moment, smirking. "Say it... Say it, Tails, and I'll give you the seed you now crave..." he crowed. Tails gasped and groaned as Shadow pounded her pussy. She could no longer resist him. She had to say it. "I'm... your bitch, Shadow!!" she cried. With that, Shadow knew he'd won. Making a few more thrusts, he pushed his cock in to the hilt, watching his new slut's expression as he came, gasping as his cum flooded her womb, his swimmers soon finding their target... "You're gonna bear my offspring, Tails..." he purred, petting her head gently, "But you're just an appetizer... The main course...is unusually late..." he mused. Tails sighed and blushed. She was his now...and Sonic was next!

Sonic's meeting place was elsewhere. It was outside Tails's workshop, and when he arrived, he found Amy, Blaze, Silver and Shade in much the same state Tails's harem had been left in. "What the... No, Tails wouldn't do this. Even if he could. It's too... vicious." he said, seeing the lustful daze even Amy was left in. Shadow soon arrived carrying Tails, the fox's harem in tow. Placing Tails on the steps of her workshop, he turned to Sonic with a dark grin. Sonic was quick to put it together. "You... You're mad that I picked Amy over you, so you do this!?" he stammered. Shadow scoffed. "You think that's what this is about? No, Sonic... If you're able to build and enjoy a harem, far be it from me to stop you...but if I can take it from you, I deserve it more, don't I?" he crowed. Sonic looked like he was about to run into action and fight him, when Shadow simply warped straight to the blue blur, lifting him by the throat! "You want to fight me? Sorry, Sonic...you're the final peace of my ultimate victory... I'm not going to break your body...exactly... I'm going to break your spirit." he grinned, dropping Sonic to the ground and making him look at his hard, black cock! The very sight of his malehood caused Sonic to gasp and glow, changing into her female form! It wouldn't be the first time Shadow fucked her either...but this time, it'd be for keeps!

With Sonic on her knees, Shadow held her shoulders and began to slide his cock against her soft breasts, trying to force his way into a titfuck. Sonic tried to break away, but Shadow held her tightly, and soon his cock managed to slide between her boobs! He then gripped the sides of her breasts and began to thrust roughly as Sonic gasped. "Lick the tip, bitch... Or go without lube!" he smirked. Sonic gritted her teeth, trying to push him off. "Y-you don't think I'll LET you do th-aaahh!!" she yelped as Shadow pinched her nipples before thrusting hard into her cleavage! "You were saying? You're already my bitch, Sonic... and unlike Tails, I'm gonna take my time before impregnating you..." he grinned. Sonic shivered and tried again to pull away, only for Shadow to suddenly appear behind her! "Down, like the bitch you are!" he ordered!

Sonic was suddenly down on her hands and knees while Shadow slid his cock between her butt cheeks, hotdogging her while she tried to crawl away! The dark hedgehog kept a grip on her ass, squeezing Sonic tightly. "Your butt feels so soft...faker." he smirked. Sonic blushed and lowered her head in shame at what was happening. "J-just... do it fast..." she whined. "You'd like that, wouldn't ya? Hmm... We'll just see..." Shadow chuckled. He continued to hotdog her for a bit, his cock sliding between her cheeks. He compared it to her breasts in his mind, just for his amusement. Sonic gasped softly, staring at the ground. She knew there was no escape. After all, Shadow had gotten his way with literally everyone else. She had no hope, no chance of escape...it was obvious. Shadow suddenly slapped her ass. "Come on...resist. Fight me. Where's that bravado?" he smirked, lining up his cock with her pussy. Sonic shivered. She didn't want to give him the satisfaction. "Try and break me, faker..." she grunted, the last flash of defiance she would ever show. Shadow nodded, and plowed his cock swiftly into her folds, making her cry out in surprise! "Consider yourself broken...and you're the fake...obviously." he sneered. As Shadow began to thrust roughly into her tight passage, Sonic groaned in defeat, clutching the dirt under her and shutting her eyes tightly as that thick dick massaged her walls. It wasn't long before he coaxed moans out of her, and this made her want to protest those moans. "N-nooo...Please... Aaaahh!! Sh-shadow, s-stop!!" she cried, but her protests only made Shadow pick up his pace, grinning triumphantly. "Your pussy feels so good, bitch! I'm gonna enjoy breeding you, Sonic!" he murred, smacking her ass again! Sonic gritted her teeth, trying not to cry. It was so far to fall, being the hero with a harem one minute, to being Shadow's bitch the next. She felt his arms reach around, his rough hands groping her breasts as his cock continued its assault on her pussy. She gasped and moaned, her tongue hanging out a little. "N-noo... Ahhhnn... D-don't..." she whined, unconvincingly. Shadow squeezed her breasts and murred. "You're loving it now, aren't you?" he whispered. Sonic would never admit that. She only fell silent, save for the moans of increasing pleasure as Shadow fucked his new, prized bitch. He knew he'd won, though, when Sonic's moans reached a fevered pitch, and her walls tightened around him. She gave an orgasmic cry, her juices splattering the ground as she came! Now, it was Shadow's turn. The dark hedgehog gave her breasts one more squeeze, and then let loose on her, making a few powerful thrusts as his cock throbbed. "Now I... am the harem king!!" he roared as he started to cum, his seed pumping in powerful spurts into Sonic's depths as she cried out hopelessly! His cum leaked down her legs, and she collapsed onto her belly as he released her. "Sh...sha-dow..." she moaned, almost longingly. In planning to take over each other's harems, Sonic and Tails had both lost...to Shadow.

The black hedgehog, the harem king, would continue to fuck his slaves while adding new servants, gradually building a truly magnificent dynasty as his mates were impregnated and gave birth. Sonic and Tails each watched as Amy and Cream birthed Shadow's offspring...but not before Tails's own baby was born. Sonic, as Shadow's prize, was bred the most. At one time, Sonic was breast feeding seven hedgehoglets... but there were no regrets. Shadow softened with time, becoming a loving father to his many children... So everything worked out in,

The End.
