So far, Tails' mind control collars had been his greatest invention yet. He had never had a better time with any of the girls until he tried out his devices, and he was thankful that he gave it a try. Now, though, he was looking to get into another girl and make his own personal harem of women to have fun with, and there were a few options for him to play with.
Blaze? Feisty, but probably worth it.
Fiona? Haven't seen her in a while.
Sally? She's still somewhere in that forest miles away.
'Hmm...' The young fox pondered to himself, mulling his options. 'Wave? ... Wait, what!?'
Why the hell did she come to mind? Those two hate each other, never mind making love.
Besides, there was no way he could track her, Jet or Storm down; those Babylonians could literally be anywhere in the world.
More and more ideas of potential candidates came to his mind, as did the lewd ideas of what he would do with them.
Immediately, the ideas of tickling and spanking them, as well as making them go outside naked came back to him, as those were already some of his go-to choices.
But before he could get any more ideas, an interruption from his work came in the form of his best friend barging into the workshop.
"Hey, Tails!" The sporting voice of a certain energetic blue hedgehog announced, as soon as her literally raced inside the building to see his pal.
"Waaahhh!" The fox exclaimed, suddenly scrambling to catch the tools and parts that he dropped into the air from the startling reaction to being surprised like he was. Luckily, he managed to catch them all without dropping or breaking a single one. "H-hey, Sonic. Back already?"
"Yup." The blue speedster replied, walking over to the younger one's workbench to see what he was working on. "How've you been, buddy?"
The twin-tailed canine placed his equipment down before turning to look at the hero of their world with his usual smile.
"I'm fine. Just running a few experiments these last few days." He answered, his grin shifting slightly.
"Anything involving Amy, by chance?" The hedgehog inquired, suddenly crossing his arms and looking at him with a curious gaze.
"W-what!?" Tails responded, his eyes looking off to the side nervously for a moment. "What makes you think that?"
"She was acting kinda weird as soon as she saw me." He explained, taking a look at one of the metal thingamajigs on the table beside him. "For one, she didn't chase or try to make out with me the first chance she got."
The fox's gaze tried to remain on his good friend to seem as nonchalant as possible.
"W-well, maybe she just took a hint?" He suggested, fiddling with his tools a little.
"Or maybe it's because she's got a thing for you, now?" Sonic suggested, causing his young friend to nearly drop the screwdriver he was holding. "She kept talking about you, and pretty much ONLY you."
Tails could feel his heart beating faster by the second, and sweat started to bead down his forehead.
"Oh really? W-well..." The yellow fox tried his best to play it cool, but could tell by the look on his pal's face that he was starting to become suspicious. "She, uh, DID help me with an experiment a couple of days ago."
Sonic's eyebrow went up after hearing the response.
"What kind of experiment? You don't usually need someone else for that stuff." The hedgehog pointed out, trying to figure out what could possibly happen with the two of them.
"It was... uh..." The canine's eyes looked around the room nervously, trying to describe it in a way that wasn't entirely dishonest. "It was just something that gave her a new lease on life, so to speak..."
"Really? That's cool, I guess." The hedgehog responded, walking over to his faithful friend. "She must be really confident about herself, since she's also going around without any underwear, too."
This made the vulpine's heart skip a beat and his face flush.
'Oh, no! I forgot about that!' Tails thought to himself, realizing that it wasn't just something he made up on the spot. "Uh, r-really? I c-can't say I noticed..."
"How can you NOT?" The blue one inquired jokingly. "Her skirt is practically asking to be looked up!"
Nervously, Tails joined in with the guys moment of laughter.
"Heh heh... Yeah..." He muttered aloud, trying to think of the best way out of this uncomfortable discussion.
"Hey, I'm not complaining." Sonic said, suddenly looking to his younger friend. "Still, I wanna see whatever it is that you did to her that made her this way. She says she loved every second of it."
"W-well..." Tails muttered, rubbing the back of his head with a hand and chuckling nervously, before suddenly changing his tone and looking like he had a sly idea. "It's a lot of work, and I'd rather not explain all of it. Although..."
The hedgehog hero placed his hands on his hips and looked at his friend with interest.
"If you want to experience it for yourself, I can give you a demonstration of what made her so full of vigor, I'm happy to show you." He finished with a grin, his tails twitching excitedly behind him.
Sonic was taken aback by this.
"Really?" The hero responded, scratching his head. "Well, I did hear her say that she loved it, and if it'll get me to go faster... Sure, why not?"
"Great!" Tails cheered, picking up one of his collars happily. "Here, put this on and I'll do the rest."
"Wait, what is it?" Sonic asked, taking a closer look at the metal device as her held it up.
"It's nothing special, just an experiment I'm working on." The young inventor replied. "It's something that makes people feel really good when they're wearing it, and it helps to concentrate on certain things."
It sounded a bit strange, but Sonic knew better than to doubt one of his best and oldest friends, so he gladly placed the device on himself without much further delay, hearing it click in place.
Tails smiled at seeing the brave and chill hedgehog hero pretty much seal his fate without question, and took ahold of the controller.
"Okay, now I'm gonna start the machine, and you're gonna feel some changes to your body." The canine warned him, before pressing the button.
Sure enough, just like the girls before, Sonic's entire upper body went limp, giving away that he was under Tails' control too.
"Phew, close call..." The boy genius sighed in relief, placing the controller down and walking over to the older male. "Okay, Sonic. As my first command, I want you to take a good look at my cock."
Immediately, the hero of Mobius obeyed the fox's orders, looking down at his unsheathed crotch with a blank expression.
"Now tell me how much bigger it is than yours." Tails commanded him.
"Wow, you're huge, Tails." Sonic replied, his face still expressionless.
The yellow canine blushed a bit at the compliment, but kept himself focused.
"Y-yes, that's right! Tell me more!"
"I've never seen one so big before. It's incredible." The blue speedster said in an even tone.
"I know, I am incredible!" Tails agreed, before grinning again. "You're jealous of it, aren't you!?"
"Yes, I'm jealous. I wish my dick was half as big as yours."
The younger male chuckled a bit.
"Well, I'm glad we got that cleared up." The vulpine commented, before moving on. "Sonic, in this state, I'M the main character, not you. And it's important that we establish this very clearly. So, I want you to address me as "master"."
"Okay, master." He droned in a response of understanding.
"Excellent! Now, you're going to lick and suck on my shaft. Show me your true, submissive self!"
"Yes, master."
Sonic lowered himself to his knees, his head now in the same level as the fox's groin.
He slowly stuck out his tongue and started to lick his friend's length from bottom to top, eliciting a moan of pleasure and delight from his friend-turn- superior.
Whilst he may have expected a pleasure this intense from a (supposedly) straight guy, Tails was gleefully surprised with the level of bliss he was experiencing from his friend.
'Holy cow!' Rang in his ears as the hedgehog gave his shaft some tender licks. 'If Amy could do it half as good as this, Sonic would've never have said no!'
"Mm, that's it, Sonic..." He moaned aloud, his tails wagging behind him as he let his new pet do its job.
Sonic continued to run his tongue along his member, savoring the taste of his flesh like his favorite kind of chilli dog.
"H-hmm... M-more, Sonic!"
"Yes, master." He muttered, before engulfing the entire thing into his mouth, the canine's cock hitting the back of his throat, before the latter threw himself back on the chair in sheer bliss.
"O-oh, yes!" He yelled in pure, unabated ecstasy. "That's it, Sonic! Suck it like a good boy!"
Sonic simply obeyed, doing his best to suck his best friend's shaft as he bobbed his head up and down, up and down, up and down.
The blue blur hadn't noticed, but his own member was hardening as he sucked and licked, the fox's cock throbbing in his mouth like it was having its own pulse.
It was a bit uncomfortable, but he was willing to put up with it in order to make his master happy.
After a few more seconds, the yellow vulpine could feel the heat and pleasure growing in his body, his balls tightening in preparation to cum.
"Ah, I'm gonna blow!" He announced, all but too late for the mammal to do anything.
His load exploded from his shaft and into Sonic's mouth, causing the hedgehog to pull his head back.
The canine's seed splashed all over his muzzle and cheeks, and a few droplets landed on his nose and even atop his quills.
Once his orgasm finally finished, Tails panted heavily, his mind in a haze.
"Oh, man... That was incredible, Sonic..." He muttered, his mind not quite recovered yet.
His old friend had been gulping down mouthful after mouthful of his spunk, before licking his mouth clean to answer him.
"I'm glad to make you happy, master." He told him, staying on his knees before him.
The two stayed like this for a little while longer, Tails enjoying his post-orgasmic haze, and Sonic patiently awaiting his next instruction.
He wouldn't have to wait much longer, as his master was ready and knew exactly what he had in mind for his new toy.
"Alright Sonic, turn away from me, and bend over." He ordered, standing up and walking over to the table for a tool.
"Yes, master."
Sonic did as instructed, bending over the table and presenting his rump for the vulpine.
With a shudder of delight, the fox had to forcibly turn his gaze away from the blue creature's defenceless asshole, cock and bollocks.
Instead, he focused on the metal object that he had taken from the table, some kind of small metal butt ring, small enough to snugly fit over something that he and Sonic both had.
Seemed that he would be treating his toy again.
"Sonic, hold still." He instructed, getting close to the blue one and holding the ring with both hands.
"Yes, master." He said again.
As the canine slowly pressed the metallic band against the hedgehog's erection, he couldn't help but chuckle a little as it fit a little more tightly than he had planned.
Though, if his friend had any complaints to make about how it felt, he certainly wasn't about to voice them to the fox.
With another button press on his almighty remote, Tails had activated the homemade cock ring, and the submissive hedgehog's shaft was soon being played with by the metal band, which began to squeeze and tighten on his member.
"Oh, yeah..." The canine growled, his tails wagging and his shaft getting erect again, watching the freedom-loving and usually strong willed hero of their world become nothing but an obedient sex toy to be used at his will.
He would've liked to just stand there and watch the scene, but his cock had other plans, and was aching for release once again.
So, he wasted no time in walking around to stand right behind his friend and aim his desperate rod at the dirt hole that he had been waiting for.
"Get ready, Sonic. This is gonna hurt." He said, his cock twitching with excitement and his tip poking the older male's rear entrance.
"Yes, master." The normally stoic hedgehog replied bluntly, not even flinching as he felt the hot flesh rod against his rear end.
With that, Tails slowly began to push his hips forward, the pointy head of his penis sliding into the blue one's arsehole.
He let out a grunt and a moan at the feel of his shaft penetrating into the rectum of his idol, hero and best friend.
'Wow, never thought I was gonna be the one on top between me and Sonic!' Tails thought to himself. The sensation of being inside another male's ass wad a whole new experience for him.
"Ngh... Y-you're... Too tight..." He groaned, trying to steady his breathing.
"Sorry, master." The hedgehog replied, his face still devoid of emotion.
Tails didn't respond, his attention now solely focused on the feeling of the warmth of Sonic's anal walls and the squeezing of his anal muscles around his girth.
Slowly, he moved his hips forward, the canine's member slipping further into the blue one's arse.
The two moaned together in unison, the sounds filling the workshop.
Tails could feel the warm flesh around him, and could see the hedgehog's hole stretch and expand to accommodate his cock.
'Whoa...' Was the only word in his mind as he stared down at the sight before him.
Seeing Sonic in such a vulnerable state was an absolute treat, and Tails had never been happier to have him under his control.
"Aaaahhh..." The vulpine groaned, the heat of his friend's hole and the sensation of his cock filling his insides making him forget all else.
"Haaahhh..." The older mammal exhaled, his face finally showing an emotion, that being pleasure, as his anus was being stretched and filled by the fox's shaft.
Tails began to thrust his hips faster, the wet smacking sounds of flesh on flesh beginning to echo through the room, along with the moans and groans of the two canines.
"Y-yeah... Take it..." The fox growled, his mind going wild with the euphoria of the situation.
From how much fun the two of them were having, getting use out of both Tails' inventions for their intended purposes of incomparable pleasure, it wasn't long until both the fox and the hedgehog were ready to blow their loads.
Orgasms built in their balls, aching and longing for the moment of sweet release at last.
It was only a matter of time, seconds even, until the big finish came for the best friends.
"Ahhh! O-oh, yeah...!" The young genius exclaimed, his tails flicking as his rod throbbed inside the blue blur's rectum.
"Master...!" Sonic groaned, his member twitching as well, his shaft aching for release.
Finally, without further delay and timing themselves in perfect synchronisity, the two o them finally blew their loads out of their cocks and into Sonic's anal passage and the workshop floor respectively.
The hedgehog's spunk splashed onto the ground below them, a few droplets hitting the fox's feet, whilst the former's rear end was filled with the latter's hot, gooey seed.
The result was the both of them panting heavily from their activity, the two boys' minds blanked from the experience and their bodies covered in a thin layer of sweat.
The vulpine's shaft was coated with the hedgehog's anal juices and his own semen, as were his friend's insides.
It took a bit of time to pull out and catch their breath, but once they had, the canine looked to the hedgehog and saw the remaining drops of his own seed slowly seeping out of his hole.
The sight made him smile, knowing that his cum was now inside the blue one's body, marking him as his property, like he had done with Rouge, Cream and Vanilla.
Now, to clean up the mess.
"Sonic..." He began taking a seat back down in the chair. "Clean your own spunk off the floor. Don't leave a single drop."
"Yes, master." He parroted yet again.
The blue hedgehog crawled over to the area and dropped down to his knees, lowering his face to the floor, and stuck his tongue out to lap up the puddle of his own cum that was left.
Ignoring the dirt and dust down there with the white cream, the hedgehog did his best to lick up every single drop, cleaning the area to a near sparkling shine.
Tails watched the display, a satisfied smile on his face.
"Good boy..."
***
With his vim and vigor regained, as well as the cock ring and mind control collar both removed, the famous blue blur had made his way out of the workshop and back to the main area of the house.
"Hey, Tails, thanks again for the demonstration. I feel really pumped now!" Sonic said happily.
"You're welcome." Tails replied with a smile. "That's what pals are for!"
"And if that's what you've been giving Amy, no wonder she's so cheerful these days." The blue one remarked, grinning at the fox.
"Yep, I just gave her a little push in the right direction."
"Well, it worked, bud!"
Opening the door and taking in the fresh air, Sonic got ready to leave, before turning back to his best friend.
"Oh, yeah, by the way, if I could get a copy of that machine that you used on her, I'll have a lot more energy when I go around fighting Eggman." He suggested, before speeding off without a rebuttal from his buddy.
The two-tailed vulpine watched his hero and brother in arms race off, the blue blur's words lingering in his mind.
"A lot more energy, huh? I'll have to see if I can do more about that." He told himself, closing the door behind him as he went back inside, already plotting his next little experiment with his new favorite invention.
