Sonata Colossale

"See?" said Sonata, scraping her fork along the nearly-bare plate. "You gotta trust me, Mic!"

Silent Mic had watched every second of Sonata Dusk's performance, and he still didn't believe what he'd seen. "Sonata," he said, "That was incredible."

Silent Mic had been certain that he'd end up shelling out the full price for the eighty-eight dollar taco platter. Sonata Dusk was a slim girl, and even though she'd told Mic that she was super hungry, it was just impossible for him to believe that she could put away the piled-high Tex-Mex monstrosity she wanted. It was her pleading eyes and hopeful smile that made him relent, and he'd simply sighed and accepted that he was going to lose that money.

But she'd eaten every bite - she was even scraping up bits of taco filling from the enormous plate - and, per the menu's promise, her meal was free. Swallowing the last bite, she pushed back from the table and patted her stomach - even though, as far as Mic could tell, it was just as flat as ever. The enormous meal hadn't given her even the merest suggestion of a belly. "Where does it all go?" asked Mic.

Sonata giggled. "A girl's gotta have her secrets!" she said, then leaned across the table and whispered to him conspiratorially. "Let's just say I'm not exactly human..."

Sonata gasped, covering her mouth. "Oh no!" she said, "I'm not supposed to tell people about that!"

"It's okay," said Silent Mic. "You told me you were a siren when we met, on your first day at Canterlot High."

"Ohhhh yeaaaah," said Sonata. "I wasn't supposed to talk about it then either."

"And then you did that thing where you and your friends tried to mind control everyone at Canterlot High," said Silent Mic. "So I think everyone knows you're a siren now."

"Right, right," said Sonata, nodding her head seriously. She pointed her fork at the last taco on Silent Mic's plate. "You gonna eat that?"

As they stepped out onto the sidewalk, Sonata smiled and put her arm out. Silent Mic took it, and together they walked arm-in-arm in the afternoon sun. Mic let a smile settle over his face as he felt the comforting weight of Sonata settling into him; Sonata was a strange girl, but she was fun to be around. She made him laugh, and she was kind - even though her friends had been a pretty bad influence on her.

And she was a cheap date, at least when restaurants offered free meals to extreme eaters.

"Ooh!" Sonata chirped, pointing down a narrow side street. "You wanna get ice cream?"

"Yeah," said Silent Mic. He couldn't say no to Sonata, and besides, ice cream did sound good. The pair of them turned into the side street, setting their sites on the ice cream parlor on the opposite side.

But they only made it halfway - exactly halfway - before dark shapes obscured the side street's far end. Large, leather-clad bodies, with their faces covered, blocked their path. On instinct, Silent Mic turned his head, looking for an escape route. But the way they'd entered was also blocked - by three of the same thugs. From somewhere above them, a voice called out. "Are you Sonata Dusk?"

"No!" said Sonata, firmly planting her feet and looking fiercely upwards. "I am!"

The voice was silent for a moment. "...Yes," it said. "You're the one I was asking."

"Oh," said Sonata. "Yeah, that makes more sense. Like, why would you look at the two of us and assume that he's the magical siren girl?" She gasped and put her hand to her mouth. "Oh no!" she said, "I'm not supposed to... no, wait, it's... okay now?" Her expression tightened in concentration. "Silent Mic, did we decide whether it's okay to tell people I'm a siren?"

"Oh, I know what you are," boomed the voice. It was female, but entirely unfamiliar. The rooftops, thought Silent Mic - whoever was speaking had to be up there. Not that that information helped him much. "You're a creature from beyond the borders of this world, Sonata Dusk. And that makes you a source of powerful knowledge."

"Hey, thanks!" said Sonata, a chipper smile breaking onto her face. "Nice to know that someone thinks I'm smart."

"That's not remotely what I meant," said the voice flatly. Then, louder, it said "Go ahead and get them. Don't hurt the siren more than you have to. The other one... hurt him as much as you want."

Silent Mic moved to protect Sonata - he wasn't much of a fighter, and there was no way for him to effectively shield her when they were being attacked from both sides... but he had to do something. He looked over his shoulder at Sonata, only to see that she was in almost the same posture as he was. Trying to shield him from the attackers.

"Silent Mic," said Sonata. There was a firmness in her voice that he didn't remember hearing before. "Do you love me?"

They'd only been on a few dates, thought Mic. But Sonata made him happy like no one else ever had, and... well, he might be about to die, so if there was ever a moment to be emotionally reckless, this was it. "Yes," he said. Tears welled in his eyes as soon as he said it, because he knew that it was the truth. "I love you, Sonata."

"Cool!" said Sonata. Not exactly the reaction Silent Mic had been expecting. "I need you to give me your love!"

"What?"

"I can get us out of this," said Sonata. "But I need you to give me your love!"

Silent Mic wasn't sure what Sonata meant, but she seemed sure of herself. So Mic just sort of... thought about his feelings for Sonata, and tried to imagine what it would be like to project those feelings through the space between them.

And apparently he did it right, because soft blue light began to surround Sonata. She wrapped her arms around Silent Mic, and felt the luminous aura as soothing warmth, while his feet left the ground.

At first he thought he was floating - floating together with Sonata, thanks to the power of love. Sonata was holding him close, enveloping him in the warmth of her aura, and her hands were lifting him higher. But he looked down to see that her feet were still on the ground. And that made no sense, unless she was taller than him...

And somehow, she was. Held next to her, he felt like he was shrinking - with her hands around his waist, his head sank below her chin, then her neck - and then his face was nestled between her breasts, resting in the soft canyon, breathing in the smell of her skin. Her breasts were huge compared to her body - they'd clearly grown more than the rest of her. Each one was like a huge, soft, fleshy pillow, far bigger than Silent Mic's head.

"It worked!" said Sonata. She extended her arms, releasing Silent Mic from her cleavage and looking down into his eyes. Her face looked huge - her bright eyes and her wide smile dominated his field of vision, like an enormous, beautiful portrait. Her hands lifted him higher and brought him in for a kiss, and his body went blissfully limp as her lips surrounded his. The moment seemed to last forever - the outside world melted away as Silent Mic shared this kiss with the girl he loved. Sonata was more than just a chipper, fun-loving young woman now; she was a living monument to beauty and love.

The thugs had been hanging back, surprised by the transformation, but the voice from above spurred them on - and shattered the moment that the two lovers were sharing. "I'm paying you goons more than enough to fight a fifteen-foot-tall girl," it barked. "Stop wasting time and get her!"

Sonata ended the kiss and set Silent Mic gently down on the pavement. His head was barely above the level of his knees - he figured she must be closer to twenty feet tall, but she probably looked smaller from the perspective of someone standing on a rooftop. Her clothes had grown with her, and he found himself looking up her short skirt before blushing and looking away. Her thighs and her butt had grown more than the rest of her, and her voluptuous backside now stretched her tights thin.

"Just stay put," she said, looking down at him. "I'll keep you safe."

Straight ahead of her, one thug finally got up the courage to charge Sonata. Compared to Sonata he looked almost child-sized - but he was built thick, and his confident charge spoke of a lifetime spent fighting. Silent Mic didn't want to bet against his girl, but this guy looked like he might be able to best a giantess.

But when the thug actually got within five feet of Sonata, Silent Mic was forced to update that assessment. With incredible speed, her hand reached down and grabbed the thug by his chest, then lifted the musclebound goon just as easily as she'd lifted Silent Mic. With no hesitation, she lifted the struggling man to her open mouth and inserted him headfirst. Her mouth widened around him, her cheeks puffing out as her tongue pulled the struggling thug deeper inside. The thug's legs thrashed and kicked, but nothing seemed to slow his descent into Sonata's gullet; she simply had more strength in her lips, her tongue, and her throat than the man had in his whole body. As Sonata pulled his knees pas her lips, a bulge began to descend through her throat. The bulge was enormous compared to the normal circumference of Sonata's neck, but it was smaller than the thug's body had been, as if he were being compressed in some way.

Sonata raised her head as she swallowed the thug, seemingly enjoying the feeling of the body, still struggling, making its way down her throat. Even for a twenty-foot tall girl, a full grown man was a big meal, especially when swallowed in one gulp... but the thug went down easy, sliding down her throat slowly but steadily. The sight of it made Silent Mic's heart race, for reasons he couldn't quite articulate to himself. Sonata was huge, she was protecting him, and she was doing it in such an effortlessly powerful way.

The bulge in her throat traveled down past her collarbone, where it seemed almost to disappear. Sonata had swallowed the thug - there could be little question about that - but whatever force had compressed him in her throat seemed to have worked again. There was no person-sized bulge in her stomach, which remained flat as ever.

Sonata looked down at Silent Mic. "So what do you think?" she asked, grinning innocently. "That taco plate was just an appetizer!"

"Sonata," said Silent Mic, "You're amazing."

"Aw, thanks!" said Sonata. She was blushing, a deep red coming over her pale blue face. "I think you're neat too, Silent Mic."

From both directions, more thugs piled in. Onefrom the front, one from the back - they'd been momentarily stunned by Sonata devouring their teammate, but the desire for money or revenge gave them the courage to try and take her down. Silent Mic pressed himself against the wall, trying to stay out of the way. He wanted to do something, but against attackers this burly, he didn't have much hope of helping.

Sonata took on a fighting stance as the thugs approached, but when they came close it wasn't her arms that went into motion. Instead, she bent at the knees and thrust her hips backward, slamming one thug into the wall with the enormous cheeks of her butt. Her growth had given her a thick, round bubble butt, bigger than Silent Mic's entire body, and when it slammed into the wall, the brick surface started to crumble inward. Almost the thug's entire body was obscured by Sonata's massive butt, lost in her soft cheeks - Silent Mic could only see his legs dangling limply from beneath.

As the next thug approached, Sonata pulled her ass away from the wall and turned to face him. He jumped at her, with a pretty impressive vertical leap, making it to the level of her belly button as he flew toward it with an outstretched fist. But Sonata turned aside, stepped back, and thrust out her chest, catching the thug between her breasts and the wall. With her giant-sized rack, she pinned the thug against the wall opposite Silent Mic. Mic was reminded of how Sonata had hugged him to her bosom, how gentle and comforting it had been - but now her boobs were a weapon, flattening the thug against the wall.

"Flattened," in fact, seemed to be exactly the right word for it. As she pulled her body back from the wall, the thug was cartoonishly compressed, almost pancaked against the vertical surface. The thug she'd butt-crushed was similarly flattened against the opposite wall, his body softly twitching.

Sonata looked between the two thugs on either wall and broke out into a gleeful giggle. Silent Mic, as awe as he was by Sonata's performance, found her laughter infectious and joined in. They weren't clear of the danger yet, but there was so much power in Sonata's body now - in her bouncing breasts, her big round ass, and her voracious mouth - that Silent Mic let himself feel at ease.

Reaching out with both hands, Sonata peeled the flattened thugs from the walls and fed them into her mouth one after the other, shooting Mic a seductive look as she pushed them down her throat. He watched the two lumps slide down Sonata's throat , distending her neck like the body of a snake, and he felt his heart rush again, thrilled by his girlfriend's display of power.

Sonata held her hand out and exhaled into it, then smelled her breath and recoiled. "Ugh, these guys taste okay, but they're not great for my breath. Do you have any gum?"

"Uh, not mint," said Silent Mic, digging in his pocket. "Is bubblegum okay?"

"Bubblegum's great!" she said, swiping an entire handful from Silent Mic, unwrapping it, and popping it in her mouth.

She only had a moment to chew before more thugs piled in, two from each side. She took a step forward, closing the distance between herself and two of the thugs, and pursed her lips. A pink bubble grew and grew - it was bigger than it should have been, even considering how many pieces of gum she'd put in her mouth. It grew until it filled the alleyway, and when the two thugs in front of her tried to charge through it, they sank into its surface like it was a giant airbag - then bounced off and tumbled to the ground.

The bubble snapped, and she drew the gum back into her mouth. She turned on her heel, towards the attackers from the other direction. They were mere feet away from her, and it looked like they'd be the first to actually score a hit. But Sonata leaned down and blew another bubble, its center between the two thugs. As it expanded, it pushed both of them to the side and slammed them against either wall. The pink bubble was translucent, and Silent Mic could see the shape of the flattened thugs through its surface; the bubble had flattened them just like her bubble butt had.

The thugs behind her - the ones she'd knocked to the ground with the first bubble - began to stand up. Sonata turned and blew another bubble in their direction, and one of the thugs threw a punch into it... only to find his hand sinking into its surface. As he struggled, his arm was pulled deeper, as if by quicksand. His friend pulled back on his shoulders, trying to free him, but once his hands touched he surface of the bubble he too was pulled in. Soon the bubble held both of them, the shape of their limbs faintly visible through the thin pink skin. Instead of letting it pop, Sonata sucked it back into her mouth, inhaling the two thugs within.

Her mouth was stuffed full, and when she swallowed, the two thugs went down her throat together. Like the others, they'd been compressed, but the bulge they made together as they went down Sonata's throat was enormous. Without discomfort, she swallowed them down - and this time, Silent Mic thought he noticed a little bulge in her stomach. Sonata's body was incredible, but it seemed that her stomach wasn't truly bottomless.

Sonata, her appetite undiminished, turned and grabbed the two thugs that her bubble had flattened against the wall. She peeled them from the wall and looked down at Silent Mic. "I think this is the last of them," she said, smiling broadly at him. "Once I finish these guys, I'll really be ready for dessert!"

Silent Mic laughed - then sucked in a gasp as he felt an arm encircle his neck. Someone had come up behind him, without making a sound, and they were poised to choke him.

The mystery attacker tightened their grip on Silent Mic's throat. "Sonata Dusk!" she shouted, in the same voice Silent Mic had heard commanding the thugs from the rooftops. "I have your boyfriend." Silent Mic twisted his head, trying to get a sense of what the stranger grappling him looked like. Her arms were a pale green, and Mic could just barely see a lock of magenta hair resting on her shoulder. That didn't match anyone he knew. Looking down, he saw the clean white hem of... a labcoat, maybe?

Sonata, swallowing one thug and sliding the other into her mouth, raised a finger. "Mmmffrmm mm hmmmrm?" she asked.

"What?" asked the stranger, tilting her head.

"Mhmmrm," clarified Sonata, pointing at the bulge traveling down her throat. Then, with a look of embarrassment: "Mmrm hmhm rmmff."

"I don't..." The stranger sighed. "Do you just want me to wait until you're finished swallowing?"

"Mmm!" exclaimed Sonata, pointing at her. She massaged her throat gently as the two thugs traveled down into her belly - which now sported a more visible bulge. "Ahh!" she said, patting her tummy, "Now then, were you threatening my little Silent Mic?"

Sonata took a threatening step towards the stranger, who flinched and tightened her grip on Silent Mic's throat. "If you value your boyfriends' life," she said, trembling, "You won't take one step closer-"

"Okay!" said Sonata, reaching down with both arms. As it happened, she didn't need to step closer; her arms were more than long enough to pull the attacker's arm away from Silent Mic's throat and grab her by her waist.

"Wait!" said the stranger, "Don't eat me! Can I... offer you a bargain?"

Sonata looked the attacker over thoughtfully. "Hmm, I don't think so," she said. "I was a bad guy for a really long time, and we never kept our promises. I think I'm better off just eating you." She opened her mouth and brought the stranger closer, headfirst towards her wide red tongue and the dark pit of her throat.

"No no no!" yelled the stranger, thrashing in her grip. "Don't you at least want to know who I am and why-"

"Nope!" interjected Sonata, and slid the attacker into her mouth. Her lips closed around the attacker's waist, and she began to suck her body deeper into her mouth, like a spaghetti noodle. From inside her closed maw, Silent Mic could just barely hear a muffled voice saying something like "My name is Doctor..." and then a word that might have began with the letter P.

Dr. P, or whoever she was - it didn't matter much now - was slim enough that she didn't need to be compressed as she slid down Sonata's throat. Silent Mic watched the shape of her body descend headfirst down his girlfriend's neck, her limbs feebly resisting as her body made its way down. Sonata saw Silent Mic watching, put her hands around his waist, and lifted him up with both hands. "Want a closer look?" she asked. Mic nodded, and Sonata held him against her bosom again, letting him rest against her big soft breasts. He watched the human shape descend down her throat, from her shoulders to her faintly struggling legs, until at last Dr. P dropped into her belly.

"Aah!" said Sonata, once her airways were clear. "Now I'm full!" Silent Mic's dangling legs brushed against her belly, which did have a significant bulge in it. Nowhere near as big as the combined volume of all the bad guys she'd eaten, but still a pretty big bump.

"Although... said Sonata, "Ice cream still sounds good."

Silent Mic laughed. "So how are you going to get small again?" he asked.

"Get small?" asked Sonata. "Why would I want to do that?"

Silent Mic, his head resting against the giant, pillow-soft breasts of his beautiful girlfriend, couldn't think of a way to answer that. "Oh! before I forget..." said Sonata, lifting him slightly so that he could meet her eyes, "...I love you too, Silent Mic."
