Sonic couldn’t decide which was more intense: the sudden chill that ran through his veins as his blood ran cold or the pit in his stomach that felt like a blackhole incarnated.  The few seconds of silence between them felt like they were stretched out to hours. 

	“Sonic… I’ve known for a really long time.” Amy confessed, putting the remainder of her chili dog back on the plate. “It was about a year into us being friends. When you dropped me off at home and you thought I went right to bed. It was really late and you looked so tired so I thought I should give you something to eat before you left.”

Sonic slowly recalled the night. It was Tails’ birthday and he had some help getting everyone to swing by and give him a good time. He especially remembered the massive five layered vanilla ice cream cake that Vanilla and Cream prepared. And that was the day he came close to nearly exposing his secret, or so he thought… 

	“I saw you hobble off into a nearby forest. I was worried and tried calling out to you but you didn’t hear me. I watched your body change. Your voice, your fur, your eyes. Everything. And I heard you whisper-”

	“I can’t let her know. Ever.”

Amy nodded her head, smiling. Sonic remembered the statement all too well. It was the first time he realized how close he was to letting someone he cares so deeply about being around that thing inside him. That beast. 

	“But Sonic… I love you. You’ll never have to worry about hurting me, beast or no beast. And tonight’s the night I prove that to you.” Amy stood up from the table, walking up to the now nervous hedgehog. She gave him a kiss on the cheek before whispering into his ears. “I want you to transform and meet me upstairs. I’ll be waiting.” 

Her soft footsteps were the last thing Sonic heard before she went up to the second story of her home, the sound of her bedroom door closing soon after.

Out of all the things he expected his girl to do tonight, comforting him about who and what he is was far from the top of his list. A rush of emotions washed over him.

Nervousness

Excitement

Elation

But most importantly of all, Sonic felt a weight of anxiety lift off of his shoulders. While his heart was still racing, an odd sense of calmness kept him in check. Like he didn’t have to worry anymore. Amy’s words and hearing he didn’t have to hide anything anymore was enough to bring a tear out of the usually peppy hero.

	“Alright… Let’s do this!”

For the first time, probably ever, Sonic was excited to bring out his more beastial nature. He knew that the moon had long since come up into the sky. All that was left was to give it a nice hard long look. Leaving the kitchen, he walked over to the living room and saw the moonlight peering through the curtains and blinds. Just touching the small rays helped stir the beast awake.

Throwing caution to the wind, Sonic parted the blinds and curtains and looked into the sky. Stars dotted the otherwise empty blackness. Devoid of clouds to obscure his vision, he looked upon the moon. An eerie sense of calmness overtook him as he looked up upon the celestial body.

	‘Its so weird. I’ve been scared of looking up at you for the longest time. Now though… You don’t even feel threatening.’ he told the moon, thinking back the countless nights he’d spent trying to never look at it in the late evening. Sonic closed his eyes and could feel that all too familiar series of sensations.

It began.

Sonic’s breathing increased as his body began to shift. Muscles grew and expanded as the beast inside finally woke up and took shape. His normal azure blue fur slowly darkened, going to an indigo shade with minor hints of purple. Sonic opened his eyes and stared intensely at the moon once again. What started as a small smile on his face, grew into a deeper grin as he felt his canines grow, extending to the fierce vistage he’s seen in his reflection  many times before.

Looking down at his hands, Sonic watched his gloves growing before being shredded apart. In their places, claws fit for rending apart monsters and hapless prey appeared. Clenching them slowly, the newly formed muscles felt tight. Powerful. Just below his wrists, his darkened fur changed to soft looking white tufts. Sonic watched push outward before seemingly pulling back in a manner similar to his normal quills. 

In his reflection in the window’s glass, Sonic could see the same eyes that would always haunt his dreams. Unlike all the times before, Sonic didn’t see some sort of monster. He just saw himself. Sonic the Hedgehog. The fear wasn’t quite gone… But now he was more comfortable staring his beast self in the face.  

	“This actually doesn’t feel too bad.” He admitted. The euphoric feeling he got from transforming was there but nowhere near as intense as it usually would be. Maybe it was just his body’s way of getting him to cooperate all this time. The beast inside just wanted to come out instead of being cooped up inside. It was a sentiment Sonic could understand all too well.

Sonic looked over his body a little more before going upstairs. As far as size goes, he certainly bulked up a bit, gaining a full foot in height, now being taller than most of everyone of his friends. Out of curiosity, Sonic turned around to look at his Tail. Same darkened blue hue as the rest of his body. It never dawned on him how much he wished it was more like his buddy’s Tails’. Something a lot more fluffy-looking.

One thing Sonic never understood was how his shoes always transformed with him but not his gloves. The normal running shoes changed to spiked cleats. They felt fine but it just bothered him, even with his new clearer state of mind. 

Sonic took a deep breath and reassured himself that everything was alright. He wasn’t losing himself to pleasure. He didn’t feel uncomfortable or like he was in another body. With his newfound comfort in mind, he walked up the stairs, careful not to break anything with his newfound size. With his nose’s new heightened sense of smell, he picked up a few new Scents.

Roses. What he could only assume to be the same oils Amy uses on her fur to keep it so lustrous. But most importantly, he picked up Amy’s scent. It was soft and subtle. Sweet like candy but natural all the same. It only grew more intense until he stood in front of her door. He took one last deep breath to calm his nerves before knocking.

	“Amy?” only now did Sonic notice his voice had gone down a couple of pitches. To him, it sounded somewhat raspy.

	“Come on in…” a sultry voice answered. 

Sonic slowly opened the door to see the room’s lights were turned off. In their place, a few candles were carefully yet sporadically placed around the room. The source of the rose smell he picked up earlier turned out to be rose petals, sprinkled across the floor. The only thing missing from the picture was Amy. For a second he thought she might be hiding in the closed bathroom door. One step forward and the werehog suddenly felt her little arms wrap around him from behind. 

	“Wha! Amy, you scared me!” He raised his arms, looking at her with a flustered look on his face.

	“Mmmmh…” she buried her face into his fur, taking in deep breaths of his scent. The act left the already flustered werehog with a slightly darkened blush. “your fur feels so fluffy and warm. And it smells amazing… Are you nervous?” 

	“I’d be lying if I said I wasn’t a little.” Sonic admitted.

	“Let’s see how this makes you feel then. Turn around.”

Sonic turned around and was greeted with the sight of a lingerie-clad Amy. A similar shade of dark indigo to his own fur, the alluring clothing made Sonic’s heart race. He’d seen his girlfriend in her underwear before but she never looked this erotic. Lightly transparent and exposing her naughty bits, medium sized bows with long strings were placed along her body, like a hand wrapped present. She spun around, causing the fabric to flutter and spin outward like a dress. The full view gave Sonic a perfect view of her figure, a lustful image that stirred his excitement. 

	“Still feeling nervous?” she teased as she faced him.

	“I’m feeling something, that’s for sure!” he barked excitedly. Amy winked and stuck her tongue out at him before pushing him towards the bed. Sonic sat down just as some smooth jazz music started to play in the background.

As the tempo of the music began to pick up Amy slowly danced in front of her transformed boyfriend. Her hands slid across her body, lightly touching herself to the beats. Her body moved and swayed like silk to the rhythm, not missing a single tone, all the while keeping perfect eye contact with Sonic. Like a wild animal, he looked at Amy with lust-driven desires. Amy’s eyes softened as she saw the effect her teasing dance was having on him. 

She reached behind her and unclipped her bra, letting it fall freely to the floor. With her hands behind her head, she gently shook her wobbly melons to a dumbfounded Sonic. She slyly smirked at his reaction, before turning around, slipping her fingers under her panties. With her hips swaying from side to side, she slowly bent over, sliding the panties down her legs, revealing her beautiful, nectar-dripping flower. With a flick of her knees, she kicked her panties right at Sonic’s face. When he pulled it away, he found her still having her back turned, mesmerizingly swaying her bubble butt, occasionally twerking and slapping it, sending ripples across the surface. She would even reach between her thighs and touch her hungry entrance, drawing out a quiet moan.

Sonic locked his eyes on her body, with his mouth hung open, almost drooling. He was so entranced that he didn't even notice his member slowly rearing its head. As if hooked on a pump, it steadily rose and enlarged, until finally, it stood tall and proud like a tree upon a field of indigo grass. Over a solid 2 feet of pure breeding desires with such a thick reach that even his massive hands could barely grab hold. The tip was a dark azure color while the shaft was a grayish blue, with veins crawling along the sides. Sitting just below the monster sized cock, his family jewels had grown to the size of grapefruits. Plump and full of seed eager to be planted into the teasing hedgehog. 

By the time the music was done and Amy stopped dancing, pre-cum was already dripping out of the tip, equating to about half the size of his normal load.

	“Uuh Ames? H-”

	“One sec! I GOTTA take a picture!” 

Amy rushed over to Sonic, kneeling down and squishing her face up against his cock. She raised the phone up high and took a selfie of herself giving it a kiss while looking at the camera. 

	“Rouge is gonna flip when she sees this! Is it okay if I send it to her?” she asked with begging eyes. He knew he was gonna have to tell everyone sooner or later so he nodded. 

Late evening at Rouge’s home.

Rouge was watching her favorite cheesy soap opera Voluntary Villinary when she heard her phone go off. Just as the male lead was about to reveal his deep dark secret, Rogue opened the picture and spat out the mouthful of wine.

	“No fucking way…”

	“What?” Shadow asked as he came into the room, holding a platter of snacks. “Did Henry finally tell his secret?” Rouge didn’t answer as she erratically typed away at her phone. “Are you seriously live-tweeting this?”

	“Get your dick out.” She ordered.

	“...Wh-”

	“You heard me! You’re not going to bed until I drain you dry and I’m soaked in cum and get a picture of it! Fuck the TV show, I’m not letting Amy think she’s hit the ultimate jackpot tonight!”

	“Rouge, what the hell did-” 

The flustered bat pulled her clothes off and bent herself over the couch’s arm rest, aiming her wide ass at her bedmate.

	“Shut up, man up and fuck me already!!!”

Soon Amy’s phone was going off with text alerts after text alerts. Instead of answering any of them, she turned her phone off and threw it into her pile of clothes, all the while smiling.

	“What was that about?” he asked, a little concerned.

	“Oh just some light teasing from me to her. But never mind them. Tonight, it's just me and you.”

Amy took the large tip of the cock into her mouth, similar to when they were entertaining themselves as they watched the movie earlier. This time, however, not even half of his tip was enough to fill most of her mouth. Her tongue played with the underside, hitting that bundle of nerves that always left Sonic trembling.

	“Amy, how do we… You know. While I’m like this? You already felt nice and tight but like this, might be a bit of an issue.” Sonic asked amidst his grunts. As excited as he is at the idea of bedding her while in his werehog form, he wouldn’t dare hurt her with his new size. He was a foot taller, bigger, stronger and more hung than ever before. 

	“Gmmph mmpumph?” her question came out as garbled gibberish while she took him into her mouth before she realized her mistake and pulled away. “Oh Sonic, you don’t have to worry about that with me. Ever since I found out, I’ve been doing alot of practice.”

Amy left Sonic to open up her closet, pulling out her “secret weapon” as she liked to call it. It was an exactly 2-foot long dildo, just slightly smaller and thinner than the genuine article that was in her mouth just seconds ago. Sonic’s jaw dropped as she began to apply a bottle of lube she had ready for her display. His cock twitched in anticipation as she gingerly lubed up the massive dildo. She set it down right in front of him and stood over it, aiming it at her pussy.

Sonic watched with bated breath as she rubbed herself across the tip of the gel cock. She gave him a wink.“Will it fit?” and slowly sank down on it.

The werehog’s eyes widened as she easily took the dildo down to the root, sitting comfortably atop the comparatively sized nutts. Her stomach bulged out in the shape of the toy like it was made of rubber. She rubbed the tip of the bulge and mugged at Sonic, “Of course it will!”  Sonic looked her right in the eyes as she pulled his cock towards her, taking him into her mouth once again.

	“F-fuck Ames!” He growled, clenching his teeth. While she couldn’t take his whole length into her mouth like before, Amy used her playful tongue to torture and tease her hunk of a boyfriend. Like a maid in a mansion, she didn’t want to leave one spec of her lover’s cock untouched. With his meat still in her mouth, she bounced up and down her toy, making the bulge go up and down accordingly. Feeling the magnum toy rubbing against her sweet spot, she moaned into the equally magnum real deal in her mouth, stimulating him further. Between her bouncing on her dildo and hearing Sonic’s moans and grunts, she was almost in heaven. But they’d get there soon enough… 

As she traveled down his shaft, she lapped away at his furry balls, tasting the pungent male aroma that came off them. It didn't turn her away. In fact, the musk left her mind feeling dizzy and eager to take him, to feel that hot liquid burning her insides. 

	“I’m getting close!” he warned her. She looked up to Sonic, giving him a devious look as she relaxed her throat and took a little under half of his cock, more than she has the entire time while between his legs. Her throat bulged, her eyes watered and the grip of her throat tightened as held in her mouth. 

Sonic couldn’t hold it in as he let out a fierce roar, letting the first load of werehog seed flood her mouth. One blast was enough to plug her throat full of the sticky fluids. What shots that went into her gullet were powerful, potent and filling, like a protein smoothie. By the third blast she pulled him out of her throat, using both of her hands to jack him off as furiously as possible, coating her face, her chest and every bit of her body in the silvery white treat. 

Tasting it.

Feeling it.

Being filled with it.

She was so engrossed by his climax that she spilled her own juices onto her not so little boytoy, covering the dildo in her sticky cum. When Sonic finally came down and the torrents of cum became soft rivers, he fell back onto the bed, panting and laughing.

	“Holy shit!” he cursed between laughs. “That was intense!”

Amy had to agree. Her stomach already felt so full from just the first few shots of his load. She had to physically pat her stomach to get a full idea of how much she just ate. Then she tried to imagine just how much bigger she’d look if she took every last drop. She couldn’t help herself. 

She scooped up the leftover cum that was still on her face with her finger and engulfed it in her mouth. Bitter yet salty, the gooey cum clung to her fur like melted ice cream. It didn’t stop her, not in the slightest. Any amount she could gather up, she swallowed. 

	“You taste so good…” she mumbled, more to herself than to Sonic.

Before she could gather up the still warm bits on her chest, she felt Sonic’s big strong hands grasp her frame, pulling her close enough to have her sitting on his lap, his still standing cock acting as a sort of backrest for her.

	“Let me…” Being the good boyfriend that he is, Sonic used his long tongue to clean the residue off of her chest. His new werehog sized tongue was far bigger, longer and more flexible than his already playful normal tongue. 

Amy watched her beast of a boyfriend extend his tongue out, sliding it across her chest, licking up the wasted cum off of her supple body. Whenever his soft tongue ran over her chest, she let herself moan out loud, loving the slight texture that’s been added to his tongue. Seeing he was doing a good job, he moved his attention to her more sensitive nipples, licking the pink pointy bits like they were a hard candy. 

	“L-lower.” She begged.

Not one to disappoint, Sonic moved his tongue further down, gathering and eating up the final bits of cum he could taste along with the new slight bump in her belly from his earlier gift. Further down, Sonic found himself tasting the sweet honey that’s been oozing out of her since they began. The warm lips of her folds twitching with every contact and rewarding him with more of her juices. After a little more teasing Amy put a hand on his chest, letting him know to stop.

	“Are you ready for the real deal?” he asked with a knowing grin. 

	“Since the first day, I rode that toy thinking of you.” She teased with a kiss on the cheek.

Effortlessly, Sonic lifted Amy up and aimed his steal hard member at her entrance. Sliding inside her felt so smooth yet even more intense than when they did it on the couch barely over an hour ago. Free of his fears and worries, Sonic brought her all the way down in one smooth go. Amy couldn’t stop the tears of joy from flowing out as she finally took the entirety of her boyfriend, her lover as he truly is. Her toy surely wasn’t a substitute for the real deal indeed. It was no match for the intense warmth that is filling her insides to the brim. She reached down to the massive penis-shaped bulge on her stomach and felt it twitching, pulsating, to the rhythm of her own heart. 

This was heaven.

	“You okay Ames?” he asked, holding the back of her head with one hand.

	“I’m more than okay!” she whispered. “But don’t worry about hurting me. I can take anything you throw at me, my big scary boyfriend!”

The challenge was something that spurred the big blue blur. Not one to turn one down, Sonic was gonna give Amy the night of her life.

Sonic pulled her into a hug and used the sitting position they were in to slowly grind into her. Cupping her butt with his massive hands, he lifted her up and pushed her back down.

Amy moaned loudly as she felt the bulge disappearing and reappearing over and over again. The constant onslaught on her G-spot made every breath more labored as she tried to hold herself back. It was all for nothing as she found herself climaxing in a matter of minutes, too excited at the embrace of her werehog lover.

	“Looks like you’re having fun, huh?” he teased, feeling her clenching around him.

	“I-its not my fault I got excited! You just felt really good is all…” she trailed off.

	“I’ll make you feel even better. I promise.”

Sonic moved Amy to face away from him, similar to when they were in the living room earlier. The new position had the fortunate effect of focusing down on her favorite spots with his new girth. 

	“Oh god yes!” she screamed. 

Sonic got a little rougher, grabbing her plump thighs from behind and fucked her in earnest. Just like he would have normally. Because she was so used to his new size and demonstrated she could take him at his best, there wasn’t any need to hold himself back. And he was gonna make good on his word on making her feel good.

Amy was moaning out of her mind as she felt electric shocks running down her body. She watched her belly bulge out even more than before with utter fascination and delight, loving how forceful Sonic was being to her. Her excitement and still sensitive insides rewarded her werehog with a series of moans that were like music to his sharp ears. Every pump of his cock attacked her sensitive folds, moving and crushing them under his monstrous member. The fine grip he had on her meant she wasn’t going anywhere, not that she wanted him to let her go…

	“K-kiss me!” She demanded, tilting her head back and looking at Sonic with pleading eyes. Without a word, Sonic happily obliged, shoving his long tongue down her throat as they locked lips in the middle of their passionate love fest. 

How many times did she cum in the last twenty or so minutes? How many times was it because of Sonic? In the end, it didn’t matter. She loved it. She loved him. She loved being fucked by him. Amy Rose belonged to Sonic. Not his normal or werehog form. Just Sonic himself.

When the two of them finally pulled away from the candle hot kiss, a devious smirk spread across his muzzle, flashing his pearly white teeth. Amy wasn’t sacred in the slightest. She was excited about what the ravenous beast had in store… Until she felt her stomach flatten.

In one swift move, Sonic pulled out, showing off the mass meat drenched in Amy's nectar. He lifted her legs higher, bringing them up until he had her knee’s right by her head and locked his hands right behind her quills. She felt a tinge of embarrassment in the position but excited, her cute little tail shaking as Sonic aligned himself. She closed her eyes, waiting to feel that intense fullness again.

… Just not where she expected.

In one smooth go, Sonic forced his length deep into her petite tailhole, earning a bellowing grunt of surprise from the smaller hedgehog. 

	“Mmmmh, nice and comfy back here.” He complimented, flexing his cock while buried deep into her back door. Locked in place and unable to do anything, Amy couldn’t stop herself as she sprayed the floor in front of her in her juices like a firehose. “Looks like that surprise got you really bad, huh Ames?”

	“Y-YES!” She screamed, unable to answer in any other way. The brutish cock worked into regions inside her she didn’t even know she had. Sonic started out slow, pumping into her tight backend carefully until he found a smooth rhythm. From that alone, the grip she had on his cock was amazing in a whole new way. The greedy hole clung to him as he pushed in or pulled out, almost teasing him to go further in.

Amy could count the bulging veins on his cock as he disappeared back into her. That is, when she wasn’t trembling under his grip, speaking gibberish or calling his name out in her stupor. Just like before, all she could do was look down to her poor belly and see a very distinct bulge popping up to say hello every now and then. The new sensations of her insides being invaded so deeply, using her own juices at that brought her close to another climax.

She knew he was close. His cock pulsated, his movements became faster. Before they got any further however, Sonic pulled completely out of her, leaving her ass gaping open. Amy was about to beg him to stuff her again but her prayer was answered when he placed her on the bed, back first and head against her pillows. 

	“If I’m gonna finish, it's gonna be right where it counts.” He snarled, looking Amy dead in the eyes. 

	“Do it.” She dared, playfully imitating his snarl.

Sonic got on top of her, sliding right back into her perfectly fit pussy, pumping into her with a series of plaps that echoed through the room. The bed squeaked and shook violently as the two beasts mated furiously with every hump growing in intensity. 

Amy tucked her hands under her pillows, clenching and squeezing them as she felt her next climax already approaching. Sonic grabbed onto her hips, keeping her nice and close as he wasn’t far behind. He couldn't help but marvel at the glorious sight before him: the lustful eyes, the gaping mouth letting out ecstatic moans, the bouncing and swaying breasts, the bulging stomach deformed by his enormous girth inside her. It was all his. She was all his. And always will be. 

Their bodies matted in sweat, the room smelling of debauched sexual pleasures. The end was near.

	“You wanna breed me don’t you? Fill me up with all kinds of werehog puppies?” she teased, using his favorite fetish to edge him forward. 

	“More than you could possibly imagine.” He grunted as he leaned forward, pressing their foreheads together. She could feel his hot breath on her lips.

	“Oh I don’t need to imagine. I can feel it. You wanna cum inside me, don’t you? Wanna breed me like some whore? DO IT!” she roared as she arched her back, gripping the pillow so hard she was close to ripping it apart. 

At that moment, the werehog part of Sonic gave him a deeper look into Amy’s eyes. He could see the burning passions aflame inside her. The years of love. The wanton lust for him. But most of all, the call in her eyes  silently telling him to breed her like he meant it. Fill her up with everything he can to claim her, fully and completely.

Louder than either of them ever could imagine, the echoes of their final climaxes left their ears ringing as they both howled to the full moon above. Amy’s eyes rolled back into her skull as she felt the molten hot seed being pumped into her, seeping into every single possible inch of her ready womb. 

Using whatever clarity Amy had left at the moment, looked down to see her belly slowly swelling up like a water balloon.For her part, she tried to keep everything inside her but the volume was simply too much for her tired body to even attempt to hold. She could feel the hot,  thick and rich cream seep out of her, joining the many stains on the bed and floor. 

After what felt like an eternity, Sonic finally ran dry of his load and unplugged his lover's cum-filled womb. In an instant, his seeds spewed out of her opening like water out of a broken water faucet.

The once noisy room became much quieter as the two lovers tried to catch their breaths. 

	“I love you.” Sonic said, kissing her on the lips.

	“I love you taaAA” her reply was cut short by a loud crack, followed by a thud of them falling to the floor. Sonic looked down to find the bed below finally gave out to the combined weight of her, him and his load.

	“S-sorry.” 

	“We’ll worry about it some other time. For now I already have the perfect bed.”

After switching into a more comfortable position, Amy cuddled up to her one true love, snuggling into the thick fur as the call to sleep took them both in the calming night. 

END

Epilogue 

	“R-rouge… Can’t… Anymore…”

	“Come on Shadow, my tits are coated in spunk! Next you gotta cum on my face! You gotta! I can’t let Amy show me up!”

	“What did… She send you…?” 

	“Just hurry up and get another load ready!”

	“Chaos help me…!”
