*Knock Knock Knock*

Tails was hard at work in his workshop, with his latest invention when the front door to his home echoed the signal of a visitor.

Removing his welding mask and turning the hot tool off, the fox quickly began making his way to the entrance to see who could be there.

'Wonder who that is?' The twin-tailed creature pondered to himself as he got closer. 'Vanilla and Cream aren't supposed to be here until tomorrow.'

When he arrived and opened the mahogany door, the vulpine anthro was pleasantly surprised to see a pink hedgehog he knew well, smiling pleasantly at him.

"Hey, Tails!" She greeted simply and sweetly.

"Hi, Amy!" He replied with a grin. "It's been a while. How've you been?"

"Oh, just busy, you know? Shopping, hanging with the girls, chasing Sonic..." The young lady explained, maintaining eye contact with her friend, even as his shifted to something that said he was sighing internally.

"That figures. If you're looking for him, he went out for a quick run... About 3 hours ago." Tails informed, his tone not changing in the least.

"Yeah, that's my Sonic~" Amy chimed, closing her eyes for a moment in a moment of lost bliss, before looking back at him like before. "But that's not what I'm here for."

Tilting his head, Tails's mind began to wonder the reason for her being here right now, if not for the boy she was literally always chasing.

"Oh, uh... Did you need something from me?" He asked, leaning on the door.

"Yep! I heard from Cream and Vanilla about your new device thingy." She informed, causing Tails's mind, and heart, to begin racing.

'This is bad!' His brain shouted in a panic, scolding him for his actions. 'You just HAD to get greedy, and now Amy's figured it out!'

"You... Did? What exactly did they tell you?" He asked, now curious to hear what her response would be, fearing the worst but hoping for the best.

"About the mind reading thing! They said you were a big help after Cream, uh... "Did something", to me at the park the other day." She explained, making Tails's worries melt away like butter in a pan, internally sighing in relief at not being killed in a few seconds by the feisty hedgehog lass. 

'I guess it's good that I decided to include the memory erasing command...' He mentally exhaled, now confident that he could deal with whatever Amy had come to ask him about.

"Oh yeah, that. What about it?" Tails inquired, playing the conversation cool.

"Well, I was wondering if maybe... I could give it a try sometime?" The pink girl requested, her cheeks turning a rosy red as she stared into the two-tailed fox's blue eyes.

"You... You do?" He asked, his eyes full of hope and his brains full of ideas.

If he got away with Rouge, Cream and Vanilla, why not see how far he could push his luck?

"Yeah! I was thinking that if I can use it to see the kind of thing Sonic likes in a girl, maybe I could... You know... Adapt?"

Tails just smiled at her query/request and opened the door further, standing aside to allow his guest to enter.

"Sure, I can work with that! Come on in and have a seat!" He offered, the hedgehog quickly accepting and stepping inside the fox's house.

"Thanks so much, Tails! This means a lot to me!" She gushed, taking a seat in the chair she sat in the last time she was here, her eyes following Tails as he made his way back to his lab.

"Wow, I wasn't expecting it to look like a collar." Amy told him as the amazing device was handed to her.

"I know, but it's the portability that makes even more effective." The vulpine replied, smiling at her as she inspected the piece.

"I guess. So... How does this thing work?" She asked, looking up at her friend with curiosity in her gaze.

"Just put it around your neck, and when I turn it on, you should be able to hear my thoughts." He explained, seeming a little too eager to start as he held up the remote. "Just remember, it's VERY important that you listen to every word I say."

The hedgehog just nodded gleefully as she attached the collar around her neck without question and awaited him to get things started.

And the moment he pushed the button, things did indeed start.

Amy's head hung low and her arms went limp, implying that Tails's control of the beautiful hedgehog had worked, just like it had the previous times with the others.

"Alright, let's test this one out..." The fox began, a perverted grin stretching across his muzzle. "Amy, show me your butt."

Without question or hesitation, the rose hedgehog stood up from her seat, turned around, and presented her rump to her new master, the skirt of her dress doing absolutely nothing to hide anything underneath it.

Her ass was already a gorgeous thing to look at, even with her plain white panties covering the majority of her cheeks and her naughty bits, but that didn't last very long.

Amy's thumbs slipping into the waistband and tugged them downwards, her panties gliding down her legs.

"Oh... Oh wow..." Tails moaned in amazement as he stared at the perfect heart shaped rear of his friend, his cock throbbing and pulsing within his sheath as it was revealed, and growing harder and longer as she bent down and stuck her lovely rear end out at him. "Sonic doesn't know what he's missing~"

"Sonic is irrelevant." Amy stated monotonously, her mind fully under Tails's control. "Only master matters to me."

"Yes, that's right." The fox replied, reaching forward and caressing the girl's left cheek, giving it a squeeze as he felt her soft skin in his grasp. "Making me happy is what you want to do. It's what you were BORN to do."

Amy only nodded in agreement with the fact her master so wisely presented her with.

"Now, turn around." Tails commanded, watching the obedient girl stand straight once again, spin around, and present herself before him. "And get naked."

Without a second wasted, the hedgehog girl proceeded to step out of her large boots and pull her dress up over her head, dropping it to the floor beside her.

Tails's cock throbbed harder than ever before as his eyes trailed along the curvaceous figure of the girl, taking in every inch of her exposed flesh and admiring every curve, his hand reaching down and grasping his dick, giving himself a few teasing tugs.

Her chest looked as amazing as her ass, and he couldn't wait to play with her fully.

She wasn't anywhere near Vanilla's level; given the age and feature difference between her and the adult rabbit, but she was still pretty respectable; nothing to whinge about.

Tails's mind had a lot of ideas with what to do with her now.

Not waiting another second, he grabbed her and pulled her in for a make-out session, immediately being returned by the sweet young lady.

Their lips clashed and their tongues wrestled with each other, the fox moaning into the kiss as his hands wandered around the rose hedgehog's body, squeezing and fondling every inch of her skin he could reach.

They started with her breasts, grasping and fondling them like a pair of furry soft pillows. They even had a go at pinching her nipples, eliciting a moan of pleasure from the girl into her master's mouth.

As one of them continued to play with her chest mounds, the other went for her sitting spot, getting a good feel of the cheeks and crack that her plain underwear had been hiding all day.

When they finally parted, both were gasping for air and had saliva hanging from their muzzles.

"Lie down, on your stomach, and stick your butt up." Tails commanded, his breathing a little erratic from the kissing.

Amy just did as she was told and laid down on her stomach atop the sofa, pushing her rump out towards her master, awaiting his next order.

Just like before, Amy's ass was hard to ignore. Her fit buttocks, dripping pussy and tight anus were all he could think about, and all he waned to play with.

He couldn't believe she walked right into this, all because of his previous success with the mother and daughter rabbits.

The canine gave her a firm slap on the ass, followed by a good squeeze and a moan of satisfaction from his partner, her ass jiggling ever so slightly as it was jostled.

"Have you ever been spanked before, Amy?" Tails asked, grasping both her ass cheeks and playing with them like dough.

"No, master." She bluntly answered, trying to keep as still as she could while her superior played with her backside like he was.

"Well, we'll have to change that, soon enough." He told her, his tongue hanging out in lust at her lack of resistance of him having his way with her. "But man, your butt is so gorgeous as it is... It'll be a shame to make it more red~"

His thumbs got on either inner end of her buttocks, gently spreading them apart to open up her pussy and asshole all the more.

"Amy, put your finger up your butthole." He commanded, aiming his rock hard rod at his new toy's cunt, ready to give her the plowing that he was sure she always fantasised Sonic giving her.

"Yes, sir." She simply replied, reaching one hand around to her ass and holding out a single digit, snaking its way to her dirty hole. "I prefer it in there."

This momentarily snapped Tails out of his lustful motion, intrigued by what she had just said.

"Oh, do you now?" He asked, his grin never leaving him. "In that case, change of plan. Put your hand back where it was."

The pink girl did as she was told, letting her hand go back to its position under her body, awaiting her master's orders.

'If she likes it more up her butt, then let's give her what she wants!' The canine suggested to himself, aiming his aching cock a little higher to get it aligned with the dirtier passage to pleasure instead.

"Alright, here I come~" He announced, his grin still on his face, plunging his shaft into her arsehole, getting a quiet scream from his toy.

"Aaah! It's in!" Amy cried out, the pain of her anus being stretched and violated sending shivers up her spine, making her toes curl and her body squirm.

If she was able to think for herself, all she would need to do was imagine that it was the blue hedgehog of her dreams giving her this kind of special attention, and she would've been in heaven right the and there.

That was the one thing she hoped he WOULDN'T be fast about.

"Not yet, it's not~" The fox declared, his hands holding onto her hips tightly as he forced himself further into her rectum, not caring for the screams and whimpers coming from the pink hedgehog.

He didn't know about her, but this was his first time doing anal, and he could already feel a few subtle differences between this and a pussy.

For one, it was tighter than her pussy, even without any lubrication provided for them.

And second, her anal passage seemed to be squeezing his rod, as though trying to force it out of her. It made sense; his knowledge on biology would suggest that this was from her body not knowing how to react at the "unusual" penetration.

But he didn't care in the slightest; being this tight only made it better, and it wasn't up to Amy's body about whether or not his cock was welcome up there.

He doubted Amy had any complaints about what he was doing, either.

"M-Master! M-more, please!" She begged him, her voice full of strain and tears welling in her eyes, despite her entranced state. "It's so tight, and big... It hurts so good!"

"Oh, does it, now?" He asked, the sadistic nature within him being fed by the cries and pleads from his partner. "Well, let's see if I can't make you feel even better, then~"

Tails began thrusting deeper and stronger into her asshole, ploughing her like the farmland that the rabbits did, not stopping until he was buried balls deep into her rear.

"Haaaa! I-It's all the way inside!" Amy shouted, her voice breaking from the pain of her asshole being so thoroughly pounded by the fox's unforgiving girth.

"A-ahhhh! I- I know!" Tails exclaimed, his grip tightening around the hedgehog's waist as his thrusts became rougher and wilder, his mind going blank as his balls began to churn, preparing a fresh load of spunk.

Amy was the same way; the sheer pleasure of her asshole being invaded like this, the way she always wanted Sonic to do to her, was enough to feel like her pussy was being just as stimulated as her butthole.

It wasn't long until both mammals reached climax together, their voices shouting out in euphoria and their bodies tensing as their orgasms rocked through their frames, filling and flooding the pink girl's anal passage with the warm, sticky liquid.

Her asshole tightened around the fox's shaft as the cum filled her anal canal, the warm sensation feeling like an enema of pure love juices.

Meanwhile, Amy's naughty fluids exploded out of her private bits, spraying everywhere on the sofa beneath her with nothing in the way of them.

Once the duo had finished cumming, their bodies went limp, and the two fell down onto the sofa, gasping and panting for air.

"W-wow... Th-that was incredible!" Tails groaned, his member sliding out of Amy's ass, a few drops of sperm escaping her anus and dripping on the sofa cushions below.

"Y-yes... Ma... Ster..." Amy replied, lying down blissfully on the couch she had just stained with her fluids, not seeming too bother about her cunt being stained by the same wet mess she just made there.

The pair of them lied there in bliss with one another for a while, until the dom of the pair had regained enough strength to proceed with the next part of his plan.

***

*SMACK*

The sound of the fox's hand slapping the bare pink ass of his guest across his knee echoed through the lower part of the house, time after time.

*SMACK*

"Thanks again for doing this for me, Tails." Amy happily told her good friend, taking her spanking like a champ with a smile o her face as she looked up at him.

She was completely dressed again, save for her underwear, which the fox now had in his possession. The collar was also off from around her neck, but after the modification he had made to it last night, it seemed to have worked, and his subjects would still obey certain orders even after snapping out of the hypnotised state.

*SMACK*

"I've always wanted to get a spanking, and I know no-one else would agree to doing it for me." She continued, not seeming to mind that Tails was enjoying this so much, or notice the boner poking into her. "Even Cream's mom turned down my offer."

*SMACK*

"Well, I'm always willing to help out a friend, Amy." The fox happily responded, bringing his hand down on her exposed butt for another firm slap.

*SMACK*

"But are you sure there's nothing else you wanted from me today?" He asked, pretending to be concerned about the original request.

The pink hedgehog shook her head at the question, taking the next spank as well as the others.

*SMACK*

"Nope! It's just this." She confirmed, the stinging of her ass growing stronger, yet somehow not affecting her. "And boy, was it worth waiting for! I wanted to remember my first spanking, and I definitely will!"

*SMACK*

*SMACK*

*SMACK*

The girl's ass was a delightful red color by now, contrasting well with her natural pink color, and he was sure that she must've been feeling the sting of the spanking she so desperately asked for.

They had been doing this for a good 10 minutes now, and Tails couldn't restrain himself for much longer. He needed to play the whole thing off so he could enjoy himself, and his latest prize.

"Alright, I guess that will do." He announced, easing her to stand up straight again.

"Thanks, Tails." She said to him again, her smile still bright as ever as she turned to look at her own rear, though her dress's skirt blocked the view. "How's my butt? Nice and red? I really hope it is."

"As red as they come." The fox confirmed, smiling as his mind was running with ideas of how to play this. "I gotta say, you took that like a champ."

"Glad to hear it; it was really fun." The girl gushed, her cheeks turning a rosy color that was her namesake, matching the shade of her butt'. "I wish I could have a spanking every day."

"Really?" He asked, raising an eyebrow. "In that case, same time tomorrow?"

Amy's eyes lit up at the suggestion.

"Sure, sounds great!"

With that, the hedgehog began merrily making her way to the front door again, this time ready to leave with a spring in her step.

"Oh yeah, and keep my undies, if you want" She called back to her good friend with no regrets. "I've got a dozen more just like them!"

As the door was shut, Tails couldn't help but smile perversely at the recruitment of his newest toy, as well as the new panties for his use.

Without a moment's hesitation, he also left the room, heading straight for his bedroom after giving them a long sniff.

'She is definitely gonna be a fun one.' He thought, a naughty grin on his face.
