Spike stood before the door to Zecora’s hut, stock-still. He’d been standing there for a good minute.

Around him, the sounds of the Everfree echoed in the warm afternoon air. A bird crowed, and Spike flinched. He twitched to the side, almost expecting Twilight to be there. But, of course, she wasn’t.

He exhaled slowly. Then, pushing through the sludge suffocating his limbs, he raised his hand to the door, clenched it into a fist, and knocked.

Immediately: “Who stands there at my door?” Zecora’s voice rang out. “And what is it you’re looking for?”

“It’s Spike!” he called back. When the door clicked open, not two seconds later, he stood with his hands clasped behind his back and a plastic grin stapled onto his face.

“Spike, my dragon friend!” Zecora beamed at him from inside. “What brings you to my homely fen?”

“I needed to ask you about something. For help with something, I mean.” Spike grinned awkwardly, his growing fangs poking up over his upper lip. He nodded over her shoulder. “Mind if I come in?”

“Of course, of course; don’t stand alone.” Zecora stepped back, smiling. “Invite yourself into my home.”

Spike followed her in. He was still a bit anxious, but not quite as much as before. Something about Zecora just tended to set ponies—or people, he corrected with an internal chuckle—at ease. Maybe it was her soothing voice, her calm demeanor, or the confident sense of mysticism that overlaid her every word.

She was wearing dreadlocks today, which were beaded with what looked like wood-carved dice. A simple white dress—or was it just a sash?—was slung over her right shoulder, and snaked down her chest and around her hip. With a start, Spike realized that he was looking down at her. It’d been a good two months since he’d last seen her, but he hadn’t realized that he’d grown that much since then. Blinking, he tried to remember when he might have matched her in height, but couldn’t.

As they passed into a sitting room, Zecora nodded toward a large, bubbling cauldron sitting above a cornerside hearth. “I was in the middle of an interesting brew,” she said. “Fear not, though—’tis only a stew.”

“Oh, good.” Spike took a seat in a lumpy-looking armchair and folded his hands in his lap. “I was worried I’d interrupted something.”

Zecora laughed, her voice rich and deep. “A visiting friend? The stew will last without me to tend.” She took a seat in a wooden, carved chair; it looked uncomfortable, but she sank into it with ease. “Now, dear Spike, explain to me this: What is this thing that you’ve found amiss?”

“Amiss? Oh!” Spike said. He flushed. “Right. That.”

Zecora’s eyebrows furrowed. “Fear not of judgement, my scaly friend,” she said. “If it’s help you need, I’m here to lend.”

“Yes. I know. Actually, it’s not me who needs help.” Spike paused, then groaned. He massaged his forehead slowly. “I mean, it is. But I didn’t want to—that is, Twilight sent me.”

Zecora raised an eyebrow. “Oh?”

“Yeah.” Spike clacked his claws against his brow. “See, she, uh, said that I have a problem, and that you might be able to help.”

Zecora inclined her head. She looked a bit concerned now, her lip gently curled. “A problem of what kind?” she said. “I must know what remedy you have in mind.”

Spike shifted uncomfortably in his seat. “Well,” he said, “how much do you know about dragons? And their, uh, maturation, specifically.”

“Of dragons, I’m afraid, not much is known,” Zecora said. “I admit I know little on my own.”

Spike nodded. “Yeah. Twilight didn’t either. And then she did some research. Turns out that dragons go through a particular severe form of”—his claws trembled faintly in his lap—”uh, development. Puberty, I guess. Not just physically but…”

As he trailed off, he glanced towards his crotch. Zecora raised an eyebrow, but then a spark of understanding glinted in her eyes.

“I think I may understand,” she said. “Does this problem perhaps have to do with your hand?”

Spike’s mouth dropped. “Uh—”

“Forgive my informality,” Zecora noted. “I was referring to your budding sexuality.”

Spike just stared. A few seconds passed, then a quarter minute. The silence in the room was almost tangible. Then, just as Zecora opened her mouth to speak again, Spike threw his hands up into the air.

“Yes,” he groaned. “Yes. I just—I didn’t think it was a problem at first—Twilight even told me it was ‘perfectly natural’—but then I just started doing it everywhere! Five or six times a day! I couldn’t—can’t—stop.” Spike gritted his teeth, clenching his claws into fists in his lap. “Eventually she found half her room covered in—stains—and I felt bad about it, but at the same time, I just can’t help it. She thought you might have some kind of cure, so…” He looked at Zecora helplessly, his hands twitching.

Zecora seemed to be deep in thought. Then, with Spike looking on, her mouth twitched—erupting into a full-blown smile.

“What?” Spike asked. “Is something funny?”

“Not at all, my dear young drake.” Zecora’s smile broadened. “I simply know of your problem’s make.”

Spike groaned and flopped back in his chair. “Great,” he said. “Because this has been going on for weeks, and Twilight told me not to come back until I’d ‘worked all this out’. Not being mean or anything,” he added quickly. “I just think I’ve driven her up a wall, kind of.”

Zecora was nodding. “As I thought,” she said. “But, my draconic friend, fear not. Your problem is dire, it is true. But certain tribes of Zebrica suffer it too.”

“Really?” Spike blinked.

“This problem exists for more than one race,” she said. “Perhaps dragons, too. And if that’s the case…”

She leaned forward. Her braids fell over her shoulders, framing her chest. Suddenly, Spike was very aware of how much of her dreadlocks were able to rest on her somewhat...ample bust.

“Then I should be of some help to you,” Zecora said. “It will take but a simple brew.”

Instantly, the tension fled from Spike’s shoulders. He exhaled and slumped into his chair. “Whew,” he muttered. “That’s good to hear.”

Zecora stood up from her chair. As she walked toward a cabinet mounted on the wall, she less walked than glided, her every step full of power and grace. Her sash, drawn tight around her waist, clung to her, highlighting every curve of her rear. Spike watched the easy sway of her hips, then mentally swatted himself. He shouldn’t look at Zecora like that—and especially not when she was helping him.

“It is fortunate indeed,” Zecora said, “that I already possess the drink you need.” She opened the cupboard and rustled around inside of it for a moment. As she pushed herself up onto tip-toe, Spike suddenly realized that she wasn’t wearing any shoes. In fact, aside from her sash, she wasn’t wearing much of anything. Her clean-cut stripes shifted easily across her shoulders and legs, a flash of a black-and-white thigh poking through as she reached for a high-perched vial. When she came down, turning back to face him, Spike found his eyes drawn to the slight bounce of her bust. Thankfully, Zecora didn’t appear to notice his wandering eye; instead, she inspected the vial for a moment before nodding to herself.

“A note I must first make,” she said, stepping toward another cabinet. From here, she retrieved two glasses; filling them with water, she then poured approximately half of the vial’s contents into each. The liquid turned a deep, rich red. “This potion is not only yours to take.”

Spike eyed the pair of glasses skeptically as she approached him. “Wait,” he said. “What do you mean? Why’re there two?”

A smirk teased at Zecora’s lips. “Your libido, I cannot cure. A growing dragon always needs much more. Yet for the mess, the drive, the soul—I think, at least, I can give some control.”

She hefted one of the glasses into the air. The hut's flickering light glinted through it, illuminating the contents in a scarlet-red glow. “This remedy will bring you peace. With proper care, you may find true release.”

She held out a glass; Spike took it, feeling more than slightly lost. With that, Zecora upended her own glass over her muzzle, gulping the contents down. A drop of scarlet liquid beaded on her throat, then dropped down to stain her sash. Spike blinked, unsure of exactly what to do.

Fortunately, he didn’t have to do anything. Instead, Zecora drained her glass dry and set it on the counter. Then, a smile playing across her face, she reached down and slowly began to unweave her sash from around her shoulders.

“Whoa!” Spike’s hands went up. “Z-zecora! What’re you doing?”

But Zecora had already finished unwrapping her chest. Spike stared, a flicker of hunger stirring in his gut as she cupped her hand to her chest, hefting one of the weighty orbs that sat there. As she gave her breast a gentle squeeze, she groaned softly. She gave Spike a knowing grin. “True release cannot come alone. As I said: come, my friend, and be at home.” She nodded toward the glass still in his hand.

Spike’s tail was twitching behind him. Something else was twitching too: a heat stirring in his loins, a hardness growing against his thigh. He tried to tear his gaze away from Zecora’s chest and found he couldn’t; in fact, he was completely mesmerized. He was powerless to resist the gentle kneading of her supple tit, the way her breastflesh oozed between her fingers as she played with herself. And her sash may have been only halfway undone, but from the way her free hand was drifting toward it, he had a feeling that she wasn’t about to stop there.

What the hell?

It was a split-second decision, but Spike could already feel that familiar feeling growing in him. That need, that desire, that lust that, until now, had been tided over only through old issues of Playcolt and a few fantasies of Rarity. But now, with a full, feminine, and willing Zecora standing before him—

—well. There was only one decision that a healthy young dragon libido could make.

Spike swallowed the potion in one gulp. He swayed for a moment, then groaned as he felt it spread through his system. He set the glass down onto a table with a clink, then took an unsteady step toward Zecora.

“That’s it,” she cooed. “Come, dear drake, and feel my tit.” Ever a dragon with a weakness for bad porn dialogue, Spike stepped forward again, and found Zecora’s chest mere inches away from his own.

Awed, Spike slowly reached out toward Zecora’s bust. His hand hovered hesitantly for a moment, not quite making contact with her coat. His fingers twitched, though, betraying his adolescent eagerness. A heartbeat later, he threw all caution to the wind and gave her a squeeze.

At first he thought Zecora was moaning. Then he realized that the soft, satisfied sighs he was hearing were coming from his own mouth. Spike’s cheeks flushed, and he closed his mouth quickly. He didn’t remove his hand, though.

Zecora smiled knowingly at him. “You like a mare’s tender feel,” she murmured. She lifted his other hand, which had been dangling awkwardly by his side. She brought it up to her other breast and rested it tenderly atop her bust. “I can sense your lustful zeal.”

Spike wasn’t about to deny that. He gave her breasts another squeeze, fascinated by the way her titflesh oozed between his fingers. There was just so much of it—so much of her. He was a good four inches taller than she was, and yet Zecora’s chest seemed to fill his whole world.

He pushed both of her boobs together, her cleavage straightening into a long, deep canyon. This time, Zecora moaned, the sound slipping unbidden from her lips as Spike kneaded her tits together.

“Y-your touch betrays a gentle bent,” she mumbled, panting slightly. “But please, explore my chest to your heart’s content.”

“Okay,” Spike said. He met Zecora’s eyes; there was a hot lust burning there brightly. He felt that same lust flare up in his crotch and nodded. “I’ll, heh, do a little more exploring then.”

Not entirely sure of what he was doing, Spike brought both hands together under Zecora’s left tit. His clawed hands lifted it gently into the air, her padded pillow just barely wide enough for his fingers to stretch halfway around. Easily the size of small melons, Zecora’s ample jugs filled out Spike’s hands nicely, her soft titflesh melting over the sides as he lifted them higher.

She watched approvingly, though curiously, as Spike lifted her breast to his mouth. Then, blushing slightly, he planted a soft kiss on her bust. Her breast was soft and warm beneath his lips, and Zecora chuckled softly when he pulled his mouth away.

“An interesting choice,” she said, smiling at him. “Go on, Spike; explore your sexual voice.”

Spike was more than happy to. He planted another kiss on Zecora’s tit, then another further down. His fingers clamped more tightly against her underboob. He could feel something hard swelling against his palm: Zecora’s nipple, fully erect. After blinking at it for a moment, Spike’s eyes flickered up to Zecora’s expectant gaze. Then, carefully, he let his tongue flicker out toward it.

His long, serpentine tongue swirled around Zecora’s nipple, surrounding it fully. Spike slowly kneaded Zecora’s breast as he swished his tongue across her areola, tasting her. She moaned softly, swaying a bit as he played with her. His crotch only tightened further at the evidence of her mounting pleasure.

Then his eyes widened. Zecora’s hands were at his waist—then his hips, tenderly unbuttoning his shorts. Before he knew it, his pants had fallen around his ankles, exposing the obscene bulge in his boxers to the world.

Or bulges, really. Zecora’s eyes lit up when she saw the twin peaks poking against the tight white fabric, and even more so when she saw the twin damp spots immediately above them.

“Goodness me,” she said. “I did not expect this part of dragon anatomy.” Her hand slipped down Spike’s waist, curving around his thigh until it was just above his crotch.

Spike moaned softly as Zecora’s hand pushed past his waistband and curled around his cocks—plural. His hemipenes throbbed in her veteran grip, another healthy glob of precum staining the front of his boxers. She gave his members a hearty squeeze, then began to stroke them up and down.

She was playing with him, that much was obvious. Teasing him. Spike hadn’t thought he could get any harder, but Zecora was proving that wrong. Her expert fingers jerked him up and down, at times slowly, and at times swiftly, all while grinding his two lengthy members together. He’d always jerked himself off with one in each hand, but the way Zecora was frotting his shafts together was driving his arousal to even higher levels.

He was more than ready to return the favor, though. His tongue swirled around Zecora’s nipple, then trailed softly across her tit before retracting into his mouth. Zecora groaned softly as he kept kissing her breast, hefting her other tit in his hand and kneading that, too. His kisses went up to her shoulder, then her collarbone, up her neck and finally to her muzzle.

Spike’s first kiss wasn’t an explosion; there weren’t any fireworks, no bombs or bliss. All the same, as his lips locked with Zecora, he felt something spark inside of him. Her tongue, more aggressive than his, prodded its way past his lips; as his tongue pushed back, first curling around hers, then pushing into her own muzzle, he felt that spark ignite into a flame, a hunger burning in the bottom of his gut. He groaned into the kiss, his hands roaming around her back, his claws raking softly at her shoulderblades.

As their mouths pressed even closer together, Spike heard a soft rush of air. Zecora had let the rest of her sash fall to the ground; unconsciously, he let his hands roam southward until they were just above the round curve of Zecora’s prime rump. She did the same, giving his cocks one last squeeze before pushing toward his tight, muscular butt. Spike moaned into the kiss as Zecora’s tits ground against his well-shaped chest, her hands groping at every inch of his ass and hips that they could reach.

Their lips pulled apart. Zecora stared at him for a moment with half-lidded eyes. She licked her lips seductively.

“For your first time, you kiss quite well,” she said. “Perhaps it’s love where you excel.”

Spike flushed. “Thanks.”

“Your body is strong; you’re in your prime.” Her eyes sparkled, and she reached to grope at his bulge again. Spike groaned softly. “A tall, muscled drake—and he’s all mine.”

“Y-you’re not so bad yourself,” Spike stammered out. “You’re...beautiful, Zecora.”

The sparkle in her eyes only redoubled. “Am I, dear Spike? Tell me; what is it you like?” She traced her long nails across his shoulders, then pulled back to give her bust a squeeze. “Is it these heavy tits of mine? I must admit, they are quite fine.”

“Not just those,” Spike blurted. His cheeks colored. “But, uh...they are pretty great.”

Zecora’s smile widened. “Perhaps you’d like a closer look. Fear not, dear Spike—I can read you like a book.”

She bent down slowly, her fingers tracing down his chest, then his stomach. By the time Zecora was on her knees, her breasts were about even with his crotch, and her mouth just above it. She shot him a smirk, then leaned slightly forward until his erections were pressed against her cleavage.

Zecora planted a kiss on either one of his heads, one after another. The moment her luscious, full lips left his full-mast shafts, each one splurted a good teaspoon of precum all over her cheeks and muzzle. She licked it up, her tongue lapping at the milky-clear liquid before pulling it all back into her mouth. It was absolutely, incredibly hot.

“A-ah.” Spike grunted. His knees quivered. “Oh, g-geeze. They’re really sensitive.”

She said nothing; just glanced up and gave him a wink. Then, with expert skill, she cupped her boobs in either hand and squeezed them around his shafts. Spike inhaled sharply, feeling her heavy bust folding around his lengths.

“Truly a pleasurable sensation,” Zecora murmured. “Yet I’d hate to ruin your concentration.”

Spike was breathing hard. His balls, feeling incredibly heavy, smacked lightly against Zecora’s underboob. She’s wrapped her breasts around his shafts and was slowly massaging them, pressing his manhoods together. “N-no,” he gasped. “Keep going. P-please.”

A smile was his only reply. Zecora just bent her head down, opened her muzzle wide, and took both his heads into her mouth.

Spike’s whole body shuddered. Neither one of Spike’s members was particularly small—as adolescent males were apt to do, he’d compared himself to more than one stallion in the pool showers, and found himself rather...overendowed. The average stallion was around seven inches hard; Spike’s members were eleven inches each, and proportionately thick.

It seemed almost impossible that his shafts, which usually came up to just over his belly button, could possibly fit in Zecora’s mouth. They were thick, too, each one half as wide as his wrist. Yet Zecora was taking them like a professional. Her cheeks bulged around them, filling up even further as he spurted precum into her mouth and down her throat. Zecora gulped his pre down eagerly, suckling on his shafts as she took even more of his length. Spike’s panting intensified; his hips began to twitch as the pressure from Zecora’s breasts and mouth around his shafts reached a fevered peak.

He was leaking too much—his pre was starting to leak out between his frotting shafts, dribbling out of Zecora’s mouth and down onto her bust. Her tits were starting to gleam with his liquid lust. Soon, Spike felt his own natural lubricant sliding across his lengths as Zecora molded her plump breasts around his base. He grunted, his hips jerking and forcing his members further down Zecora’s throat. She slurped him down eagerly, swallowing his heads as his pleasure mounted further and higher.

“Oh, geeze,” Spike groaned. A familiar pressure was starting to build in his crotch. It felt somewhat...different, though. Stronger. More intense. Hotter, even, burning with the hunger flickering in his gut. “Zecora. I’m gonna—I think I’m gonna cum.”

Zecora didn’t pull away. If anything, she only redoubled her efforts. She squeezed her breasts around his cock,  her soft titflesh folding around his length as her muzzle pumped up and down his rods. Spike groaned, then gasped, the muscles around his crotch contracting to an impossible tightness—and then releasing.

His hips jerked wildly as he came. Zecora’s boobs bounced and jiggled as he humped them, his shafts bulging and swelling with his load. Zecora swallowed his first burst, eagerly gulping down several thick ropes of Spike’s cum. Then, with a gasp, Spike felt his smooth shafts pop free of Zecora’s lips. The recoil of his orgasm pushed his hips further back, leaving his spasming, lurching cocks to empty their load all over Zecora’s plump tits.

Spike gasped for air as his orgasm pumped pure pleasure through his veins. Each contraction of his shafts spilled even more of his thick, white cream all over Zecora’s bust. Soon, her tits were drenched in white, with stringy ropes of his spunk oozing down the sides of her tits. Spike’s balls lurched beneath his cocks; he felt like they were trying to unload every last drop of cum from their fat, heavy depths, and adding even more white stripes to Zecora’s coat in the process.

A hot, heavy pulse of energy thrummed through him. As Spike’s shafts burst with their last splatter of cum, he groaned deeply as an intense warmth began to spread through his body. His eyes squeezed shut, a low, bestial grunting escaping from between his lips. He could feel his muscles flexing, his bones shifting, his balls growing heavier and fuller between his legs until it felt like he’d never cum at all.

When Spike’s eyes opened again, he blinked rapidly, trying to remove the blur from his vision. It took him a moment to realize that Zecora hadn’t crouched further down—and yet his shafts, which had fit perfectly between her cleavage before, were now resting on top of her muzzle. Spike gaped, then glanced down to look at himself.

His biceps were thicker, his chest wider. His shoulders were broader, and his arms looked like they could bench-press twice what he could before. With a look of awe on his face, Spike watched his twin cocks twitching, a steady stream of jizz still dribbling out from his tips. It mixed with a new river of pre, and streamed down to cover Zecora’s face and chest with his musk and seed. She licked her lips, wiped her cheeks, and gave Spike’s tip one last kiss. When she stood up, Spike noticed, with no small surprise, that Zecora only came up to his chin now.

“I’m—I’m bigger?” He gaped down at his claws, watching them flex. His forearms were thicker, too. Beefier. And his manhoods...

Zecora gave his twin shafts a squeeze, and Spike moaned. He was like putty in her hands. “Indeed you have—you’ve grown quite tall. But that alone is far from all.”

Spike stared down at his cocks. Before, they’d come up to around his stomach, but both looked to be pushing against the bottom of his chest by now. He rubbed his stomach softly, and nearly jumped when he felt a set of clean-cut abs rubbing against his palm.

“What the—is this because of that potion?” He gave Zecora a wide-eyed look.

“A guess as good as any,” Zecora said with a smirk. “As you’ll see, its effects are many.”

Her hand slid down his shafts, then circled around his bases—or tried to, at least. They were now far too thick. Spike’s cocks had grown at least two inches taller, and that much wider around to boot. Spike moaned as Zecora’s skillful fingers drifted down to his nutsack. His balls felt so...heavy. So full. His hips twitched, and he could feel his fat nuts smacking against his now-muscular thighs. They felt like they stretched halfway down to his knees—they must have been more than ten inches in diameter! He could actually feel his seed sloshing around inside of them! How was that even possible?

The potion, he realized. He did his best to smirk back at Zecora. He was trembling, though, both with awe and arousal. “So you’ve got to get me big enough to ‘release’ me properly, huh?”

Her answering smile was all the reply he needed.

There was a hunger growing inside of him. It was a flame, flickering, sparking, burning. It was a dragon’s flame: a want, a need to own, to command. Zecora’s words, her smile, were all he needed to throw all restraint aside and embrace that flame. Instantly, an all-encompassing lust flared up inside his chest.

Spike’s pupils dilated. His claws flexed, and a low, lustful growl escaped his lips. With a guttural voice, he chuckled, “Then what’re we waiting for?”

In the blink of an eye, he’d grabbed Zecora—roughly, though not painfully. He kissed her just as harshly, pressing his lips against hers as her chest squished against his. His hands roved eagerly across her back, his upper arms kneading her plump tits between his biceps as he explored every inch of her body. She moaned into the kiss, her deep, rich voice only further fanning the flames of his desire.

He pushed her to the floor, their bodies tumbling over each other. His heavier body pressed hers to the floor, and he began to grind his cocks against her belly. Spike kissed her long and hard, then began to kiss her rapidly across the face, planting his lips against every inch of her body all the way down to her crotch. All the while, Zecora moaned as Spike kneaded her wide-spread ass cheeks and grinded his cocks against her thighs.

Zecora groaned richly when Spike’s mouth first poked against her feminine lips. “So it has come to be my turn?” she grunted. Both her hands were on the back of Spike’s neck, pressing him gently down toward her crotch. “Go on then, Spike—my flesh you’ve earned.”

That was just what Spike had wanted to hear. His tongue lashed out at her lips, and Zecora moaned. His long, serpentine tongue curled around, then into her marehood. He tasted her sweet insides for the first time, lapping around her sides before delving into her every heated crevice. Zecora was panting, her huge chest heaving as Spike’s tongue twitched against all of the right spots. Her breaths were getting heavy, her thighs tensing and flexing in his grasp.

“I think we’ve reached”—she gasped—“the height of our fun. Spike, dear drake, I’m about to—cum!”

Zecora’s head jerked back as she came, her whole body lurching with the pleasure of orgasm. Spike tasted her sweet, tangy nectar on his lips and lapped it up before swallowing it down. Zecora’s marecum tasted good—and her flavor on his tongue only drew his swelling draconic passions even higher. His long, serpentine tongue teased every last drop from her orgasm, slipping around her labia and squeezing them until her juices were streaming down Spike’s chin. His hands were around Zecora’s hips, now, and his face was still buried in her crotch. As such, he didn’t notice at first when she began to grow—but grow she did.

Zecora groaned, her afterglow spreading through her veins. Her muscles rippled, shifting as her torso lengthened, her legs growing longer and thicker. Her thighs flexed lightly as they passed Spike’s stomach, squeezing his waist between a pair of well-built legs. Spike grunted; Zecora’s hips were widening, her asscheeks filling up more of his claws by the second. Her already plush rump was growing even more so, her burgeoning butt pushing her hips another few inches into the air to match her growing body.

When Spike finally picked his head up, Zecora was smiling at him. She was doing so over a pair of breasts the like of which he’d never seen before. Each one would have easily been the size of a large canteloupe had she been her normal size. Now, though, she was anything but. She was bigger, somehow, filling up more of his vision, and the same was true for her chest. On a figure that had to be just over six and a half feet tall, Zecora’s tits were the size of small watermelons: a pair of huge, heavy jugs just begging to be squeezed and fondled.

Spike gaped for a second. For a moment, his libido receded as he stared at the most incredible feminine body he’d ever seen. Zecora kept smiling. She cupped one of her enormous breasts in her palm and hefted it upward, making a visible effort to hold up that much weight. Her nipple, fully erect, bounced and quivered in the heated, musky air. Spike felt a line of drool slipping down his cheek and quickly slurped it back up.

“It seems my potion has done its work,” Zecora purred. “And that it’s made your interest perk.”

“Oh, wow,” Spike said. It was a struggle not to pant. “Zecora—you’re so big.”

“As are you, my growing friend.” Zecora smirked. “Yet our fun today’s not reached its end.”

Spike’s twin cocks throbbed. His libido came roaring back, and with a vengeance. He slid over beside Zecora and slipped a hand around her waist. The weight of her huge breasts pressing down over the back of his hand was incredible. His other hand was devoted to his twin erections—which, he was beginning to find, were getting increasingly difficult to control.

“How big are we?” Spike asked. He pulled Zecora closer to himself, and groaned when she darted forward to kiss him. She pulled back after a moment, kneading her breasts between her palms.

“Not too big, if that’s what you seek. Yet our full size…” Zecora stole another kiss from him, her tongue worming its way into his mouth. Spike could taste the lust, the hunger, the need on her lips and savored every drop. When Zecora pulled away, they were both panting. Zecora wiped her mouth and shot him a grin. “...we’ve still to reach.”

That hunger flared up in Spike’s gut again. Before he knew it, he’d tackled Zecora to the ground, his heavier body pinning her to the floor.

Their lips pressed together, Zecora attacking him as eagerly as he did her. Her breathing was frantic and rushed, the dance of her fingers along his neck electric and intimate. He pressed himself more tightly against her, their legs wrapping together as their tongues dueled, fighting for supremacy. His claws grabbed for her mane, pulling it, even as her hands curled deftly around his scales. Until his chest felt empty and ready to burst, Spike didn’t come up—and then he did only briefly, gasping for air before diving back down.

Spike’s cocks grinded against Zecora’s thigh. His fat, puffy tips prodded against her marehood as his shafts frotted together. She was leaking all over him, the scent of her arousal mixing with his musk as they panted and moaned and sweated together. Spike’s hands roamed all over her body to explore every nook and cranny of her figure. He cupped his hands beneath her breasts and squeezed; he traced his fingers along her hips and waist; and he squeezed her ass with a hunger like none he’d ever known.

Their bodies grinded together, Zecora’s soft fur rubbing against Spike’s hot, smooth scales. She nipped at his ear and he growled. His balls felt so full, so heavy with seed; he needed to spill it on her, needed to spill it inside of her.

The warmth of her body against his was driving him crazy. Spike was panting, his chest heaving. The burning feeling in his chest was rapidly becoming a blazing inferno. “I can feel your growing lust,” Zecora murmured into his ear, before nipping his neck playfully. Spike growled again, his irises dilating with need. “Enjoy my body—I know you must.”

Oh, but he did. The coy grin on Zecora’s muzzle set his libido roaring all over again. There was a fire in Spike’s loins, precum dripping down his shafts and running down his thighs. All the blood had rushed to his groin, leaving him feeling lightheaded and dizzy. A surge of aggression pushed up through his chest, and he pushed Zecora to the ground, his claws pinning her to the floor as he rocked back onto his knees.

Zecora moaned. She had one hand firmly clamped between her thick thighs, her juices streaming down her legs as she pleasured herself. Spike’s shafts brushed against her feminine lips and her groans redoubled. The weight of Spike’s manhoods, each one a foot and a half long, and equipped with a pair of balls the size of cantaloupes, was enough to keep her down, whimpering for more. His erections pushed across her crotch, straining against her stomach as they dribbled pre all across her fur.

Spike’s fingers found Zecora’s massive breasts, and he began to knead them as he humped her crotch. What felt like gallons of warm, soft titflesh oozed between his hands as he ground his cock against her belly. He dove down to kiss her, then planted kisses all down her neck to her chest. Zecora gasped when Spike’s lips latched around her nipple, then groaned softly as he suckled on her like a foal.

Spike pulled his lips away with a pop. His engorged manhoods were streaming pre down Zecora’s thighs like a river, and her own marehood was hot and puffy. Spike pushed himself down toward her and let her magnificent bust squish against his chest; he bounced his pecs, feeling her nipples grind against his own as he humped her again and again.

Zecora’s fingers roved across every inch of his body, yet not once did she keep from stimulating herself. Her gasps were growing sharper and shorter, higher-pitched as she drove herself to a peak. Driven by a hunger he barely understood, Spike bit down on Zecora’s neck—not hard, but enough to elicit a soft gasp of pain and pleasure—and then went down on the rest of her, running his tongue up and down her neck as he humped his huge shafts against her.

“A-ah!” Zecora choked on her own arousal as Spike buried his face in her mane, taking deep breaths of her scent. “My lustful needs, I’ve yet to free. Spike—tell me just what you’d like to do to me.”

Spike growled, his lust flaring up. He seized Zecora’s shoulders in his big claws, then pressed his mouth against hers until they were both struggling for air. Pulling back, he gasped, “Oh, geeze—Zecora. I want to fuck you. I want you to feel my cocks inside of you. I want to fill you up with my cum. I want to—oh, Celestia, I need to fuck you. Oh fuck, oh fuck, oh fuck—”

 “Oh, Spike,” Zecora gasped, “my body’s gone numb. I do believe—I’m about to—cum!”

Zecora’s howl of pleasure filled the room. Her marehood spasmed around her dancing fingers; beneath his engorged shafts, Spike felt her belly twitch and lurch as her whole body contracted with her orgasm. Her sweet tangy scent filled the air as she came, her whole body convulsing with pleasure. And then, just like before, she began to grow.

Her torso lengthened, her muscles thickening. Her legs and arms pushed out further on the floor. With a start, Spike realized that Zecora was growing to match his own height—and then pushing even past that. Her hips widened, her ass and thighs thickening. Yet it was her chest that was the true subject of growth.

As Zecora neared seven feet in height, nearly two inches taller than Spike, her breasts began to push outward. Already larger than any mare’s in Equestria, they were now pushing down toward—or even past—her stomach. Spike’s chest and chin squished against the twin pillows on Zecora’s chest, surrounding him with her softness and scent. As his ears were filled with Zecora’s moans of pleasure, Spike found that her growing body beneath him was pushing him even closer to his own peak. He panted, groaned, humping Zecora’s soft body until he could hold himself back no longer.

Rearing back, Spike roared with pleasure. His hips bucked, and his cocks erupted with his hot, virile spunk. Thick ropes of cum splattered all over Zecora’s stomach and the undersides of her breasts. Each of his engorged cocks throbbed and lurched, covering and matting her fur with his sticky seed. Before long, her entire stomach and bust were covered gooey blogs of his pearly white load. Spike groaned, and began to grow with her.

His head pushed up toward the ceiling. His chest broadened, his shoulders widening as his pectorals jutted out further in front of him. His arms thickened as his stomach tightened, pounds of definition sculpting his body into the perfect specimen of masculinity with each passing second. His cocks, already enormous, pushed up further until they were at just the top of his abs, a pair of massive slabs of meat that could split any mare in two.

Spike’s growth didn’t stop for an entire thirty seconds. During that time, he was completely lost in the haze of growth. It was like a hot, burning feeling deep within his gut; it was one of the most pleasurable things he’d ever felt. He felt his mind slipping deeper into desire, a lust for more and more size filling him as thoroughly as his greed growth had all those years ago. He saw Zecora beneath him, saw her massive chest and quivering marehood, and something deep within his reptilian mind said mine.

Now over eight feet tall, and nearly five hundred pounds of muscle, size, and cock, Spike was able to easily pin Zecora to the ground beneath his weight. His nostrils flared with need as his shafts restiffened; his arousal was returning with a vengeance, every one of his draconic desires and lusts building up at his crotch until he felt just about ready to burst.

“Put it in,” Zecora was begging him. Her well-endowed body rolled and rippled beneath him; he loved how powerful he felt above her, how her whimpering drove him nearly mad with lust. “Put it in, and let us now begin.”

Who was he, Spike reflected, to refuse a lady in need?

And besides, he was in no condition to turn her down. Some part of his mind, still lucid, poked up through the haze of lust, saw Zecora’s trembling bust, and dove right back down toward his libido. Spike was horny enough by now to just growl in need. He grabbed Zecora by the waist and grunted. His balls, even after unloading over a gallon of seed over Zecora’s chest, still felt incredibly full. He was so huge, so powerful—

—and so unbelievably horny.

His cocks prodded against Zecora’s wet entrance. Her warm pussy lips rubbed against his shafts, teasing him harder and harder. Zecora was groaning for him to fuck her, to put it in, to shove himself inside of her. Evidently, the potion had done its work on her as well, and Spike had exactly zero problems with that.

Slowly, with surprising care and caution, he began to ease himself inside of her. Zecora let out a muffled groan. She was tight already, and Spike was pushing not one, but both cocks inside of her. Each one was already near as thick as a normal stallion’s forearm, and both would soon be stuffing Zecora’s pussy full of hot dragon meat.

Inch by inch, Spike pushed himself inside of her. Zecora’s eyes rolled back, her muzzle gaping open as he stretched her incredibly, impossibly wide. “Never have I felt a stallion so big,” she panted. “Deeper inside me, I beg you to dig.”

Spike bit down on his lip, hard. It was almost impossible to control himself now. His cocks were lurching, splattering Zecora’s insides with pre as he pushed himself inside of her. He roughly shoved the last six inches into Zecora’s snatch, hilting himself inside of her. His groans mixed with her wail of pleasure—and then he began in earnest.

There was no slowness no, no ease or caution. Spike just seized Zecora’s plump hips in his claws and began to fuck her with all the fury and lust that a growing dragon could muster. She yelped, her head jerking from side to side as his heavy balls smacked against her rear. Her enormous boobs bounced up and down on her chest as the sound of flesh slapping against flesh filled the room. She was whimpering in helpless pleasure now, her helpless pussy doublestuffed with Spike’s twin cocks. He could even see, if he looked carefully enough, a pair of bulges poking up against the skin of Zecora’s stomach.

She glanced down, panting, at her belly. A grin crossed her face. She held both her hands over her gut and began rubbing. Spike growled with pleasure as Zecora massaged the tips of his cocks, even as he hilted himself inside of her again and again. His muscles rippled and flexed, his arms and chest bulging with definition every time he stuffed her full.

“Fuck me, fuck me, fuck me wide!” Zecora groaned, still squeezing his shafts through her stomach. Her belly bowed out every time Spike buried himself inside of her, his twin shafts flooding her snatch with rivers of precum. “I need you to cum inside!”

He was more than happy to do so.

Spike’s thrusts went wild as he buried himself to the base, and unleashed his load deep within Zecora’s cunt. Zecora’s moans filled his ears, her velvety inner walls clamping down around his rock-hard shafts. Spike growled his lust and pleasure with a voice filled with draconic power. Fat globs of his cum splattered inside of Zecora’s marehood, cupfuls of his gooey spunk filling her to bursting.

And she was being filled up—there was more than enough cum for that. Spike’s nostrils flared as he slammed himself inside of Zecora again and again. His cocktips bulged impossibly wide, his volcano of an orgasm now pumping quarts of cum into her by the second. Zecora moaned helplessly, her juices streaming down Spike’s ridged shafts as she came along with him. Soon, her belly was rounded out with his cum; it sloshed from side to side as she twitched, still impaled on his cocks.

Spike groaned deeply. His eyes were squeezed tightly shut; if not for the hardness of his scales, his clenching fangs would have bitten right through his lower lip. His whole body shuddered as waves of euphoric pleasure washed over him—both from the force of his orgasm, and from the heat of his oncoming growth.

This time, though, the severity of his growth spurt took the both of them by surprise. The potion was more than doing its work—Spike’s draconic libido had gotten some of what it wanted, and it wanted more.

Powerless beneath the tide of such monstrous arousal, Zecora’s body followed after him. Spike grunted, then snarled as a wave of growth flooded his body. His chest bulged out, his legs thickened. His cocks grew until they were poking up against the undersides of his pecs, and his balls grew and grew and grew, until they were each bigger than his head, and absolutely loaded with cum.

The rest of Spike’s body was growing, too—and it was going into overdrive, as if for payback for the mind-blowing pleasure that had sent Spike’s rational mind reeling. His legs lengthened, pushing across the floor as Zecora’s body swelled beneath him. The sensation of growth, of power and size, filled Spike’s mind, which only pushed back with an animalistic desire for more. And more he got: Before long, his clawed feet were pushing against the opposite wall of the cottage, and his whole body stretched across a full half of the entire building.

Panting, Spike collapsed on top of Zecora’s chest. Her boobs squished out beneath him, rippling like a massive waterbed. His softening cocks slipped out of her abused pussy, and an absolute flood of his jizz cascaded out behind them. Spike groaned, his eyes fluttering open as a touch of lucidity returned to his mind.

Zecora smiled up at him. “And how does my lusty drake fare? It seems you’ve filled me without a care.” She prodded against the sides of her cum-filled belly; it sloshed loudly, pinned beneath Spike’s weight. He groaned again, the sound of his own virility getting him hard again.

“Zecora,” he panted. “Why—why am I so horny? Aside from the potion, I mean.”

Something twinkled in Zecora’s eyes. “A dragon’s lusts are never small. They will only grow as you grow tall.” She gave his bicep a squeeze; it was now thick enough that her fingers couldn’t even wrap halfway around. “And as you grow, your needs are great. So tell me, Spike—have you found a mate?”

“Aside from my hand?” Spike chuckled, then blinked. “Oh. You—I guess.”

Zecora gripped either of his shafts and squeezed them between her fists; Spike moaned, a spurt of pre slicking the space between them. “Me? Perhaps. It is my marehood you’ve now attacked.”

Her smile twitched, and Zecora’s hands found Spike’s rear again. She gave his muscular rump another squeeze, and his huge body tensed with a new wave of arousal. “You’re now so big—we must be close. Perhaps you need just one more dose.”

Spike swallowed. “I—they’re still really hard,” he said. “And the last one helped, but my balls still feel so full—”

“Fear not, dear one,” Zecora purred. She stroked his scales gently, the sultry look returning to her eyes. “We’ve not finished our fun. The dragon shall have that which he hunts—if he’ll just stuff both holes at once.”

“Both—” Spike’s exploring fingers found Zecora’s ass and squeezed. “You mean—back there?”

“Perhaps two will best serve stimulation.” Zecora nibbled on his neck thoughtfully, and Spike groaned, shifting his weight atop her. “And there you’ll find your consummation. A dragon’s cocks must not go to waste. And so, dear Spike—fill me up with haste.”

Spike realized that Zecora was panting slightly, and that there was sweat beading on her forehead. Noticing his look of interest, Zecora just smirked. “And it’s correct—I like things new. Especially if I am being stuffed by you.”

“Okay, then.” Spike felt the heat returning to his chest as his members stiffened. “How, uh, should we do this?”

In response, Zecora just turned over onto her stomach. Her massive boobs pushed her up a bit off of the floor, her nipples grazing the ground as her breasts squished out beneath her. Spike gave a soft “oof”, Zecora pushing him back to give herself room. His eyes widened when he felt the top of his head bump against something. It was the ceiling of Zecora’s hut—and he’d hit it on his hands and knees. His cocks swelled a little bit prouder at that realization, grinding against Zecora’s soft asscheeks and eager to be let free.

Zecora was presenting to him. He could see the entire stretch of her taint, from her dripping marehood to her puckered hole. Both were slick with his precum, mixed with Zecora’s own natural lubricant. Walking himself forward on his hands and knees, Spike pushed his body above Zecora’s, slipping himself between her back and the ceiling. His pecs were thick enough that they pushed against Zecora’s shoulder blades, making the fit a tight one. Meanwhile, his own shoulders pushed against the roof, the thatched roof crackling as his muscles flexed and bulged.

Zecora panted, Spike’s members prodding against her rear. He reached back with a claw and tenderly arranged them so that they were each aligned to a separate hole. His lower cock, lined up with her marehood, felt a familiar, soft sensation. His top one, though, brushed against her puckered asshole and found an alien space awaiting it—yet one that made him no less aroused.

Her marehood welcomed his head in, but easing himself into her ass took a bit more effort. Spike gritted his teeth as his shaft kissed Zecora’s taint with a constant drool of precum, then grunted when he felt the head finally slide in. Zecora groaned when she felt his girth pop inside of her, then all but melted around his shaft as he eased himself further in.

He thought he’d known what tightness was before, but this was a whole new world to him. The slickness of his pre around his cock eased his entry, but he had to push more and more of his length in as her warm insides parted around his girth. He flexed his hips and jerked his shaft another half-foot inside of her. Zecora yelped in a mixture of pleasure and pain, then whimpered softly as Spike’s penetration continued.

The sensation of both her holes around his members was...bizarre, but incredibly hot. One was warm, open, soft; the other tight, slick, and choking. Spike pumped his shafts in and out of Zecora, savoring the different ways her body caressed and hugged his girth. He slipped one arm beneath Zecora’s chest, beneath her breasts, and hugged her to himself. He felt a feeling of dominance welling up inside of him like nothing he’d ever known before. It was a sensation of power, of control, and of all-encompassing desire.

He nipped her neck roughly; Zecora moaned as he shoved another foot of his cocks inside of her. “Are you ready?” Spike murmured. Zecora’s quick, desperate nods gave him his answer.

With a mighty growl, Spike began to pump his hips like a piston. He shoved himself forward, hilting himself inside of Zecora. As he hugged her closer, he could feel the massive bulge of his shafts pressing up against the palm of his hand—her body, even enlarged like this, was just too small to contain his manhood. The thought turned him on even further, and his thrusts increased in intensity.

He’d begun with short, sharp thrusts, the sensual slide of his ridges against Zecora’s entrances sending the two of them into a haze of pleasure. Yet now, he began to thrust into her long and hard, almost pulling out entirely before slamming himself back into her, again and again. Zecora’s giant body shook, her massive breasts and ass quivering as his even more massive body made her into nothing more than a tool for his pleasure.

His balls, huge and fat with cum, slapped against her ass and thighs with every thrust. They hung down almost all the way to the floor; each one was nearly the size of a fully grown pony, but the churning and groaning of the cum inside betrayed a volume much greater than their apparent size. Zecora’s insides spasmed around Spike’s cock, and he snorted, his nostrils flaring with pleasure. His enormous nutsack slapped off of Zecora’s ass with each thrust, sending a shockwave of intensifying pleasure and tightness through his entire body.

The pressure in his loins was intensifying. His every muscle tensed, his legs and chest bulging with definition. Sweat streamed down Spike’s forehead as he fucked Zecora to oblivion, her eager yelps and squeals the only thing he could hear. The ceiling was beginning to crack as his ironlike shoulders rubbed and smashed against it, his enormous frame utterly dominating the room.

“Nggh.” Spike clenched his jaw, his eyes squeezing shut as he fucked Zecora like a cocksleeve. The pressure at the base of his shafts was unbearable; his every muscle was twitching, his teeth grinding as he felt his balls swell with his oncoming load. “I’m—oh, fuck. Zecora, I think I’m going to—to—”

Zecora chuckled. “Go on then—make me whore. So long as you jizz inside of my back door!”

Spike was more than happy to do so. With a bestial roar, he slammed his hips against Zecora’s. He hilted himself fully inside of her, her stomach bulging obscenely around his cocks. The pressure in his loins blew like a damn—and then a flood of cum was rushing into Zecora’s rear, some of it joining the existing sea of jizz in her womb, but even more rushing into her ass and gut like a tsunami.

Zecora’s eyes shot wide open when she felt Spike’s cock bulge enormously in her ass. Then she lost herself to moans, wailing as shot after shot of Spike’s gooey spunk launched against her insides. Spike couldn’t hold it back—didn’t want to hold it back. His thrusts went crazy, his whole body jerking with lust and release as he unleashed his full load into Zecora’s rear. Gallons and gallons of cum rushed in to fill her; his balls, fat and full and groaning with seed, shuddered and lurched between his legs, their unfathomable depths unloading into Zecora’s swelling stomach.

And swell it did. Zecora’s eyes rolled back, and her tongue lolled out of her mouth. Her stomach was spreading out beneath her; by now, it was almost as large as her bust, and still growing. And she was growing, too, her size pushed even higher by the strength of her orgasm. Except Spike was still growing, too.

The roof creaked against his growing, shifting shoulders, and then split right down the middle. Spike roared again, his deep voice echoing through the musky Everfree air. Zecora’s rich voice rang through the clearing as the two of them burst free from the house, their massive bodies too large to be contained by a tiny pony dwelling.

Spike’s head pushed further and further up into the sky—and Zecora’s body followed. With her stomach beneath her body, she was powerless to stop herself from rising further and further away from the ground as her belly ballooned out beneath her. Spike’s massive cocks flexed and erupted inside of her, each passing second bringing a new tidal wave of spooge. Spike’s ass-clad cock shuddered for a moment, bulged hugely—and then erupted like a volcano, an impossible quantity of his spunk rushing through Zecora’s body, filling up every tunnel and place it could find.

Zecora choked for a moment; a hacking cough overtook her, and soon enough she found herself hacking up huge wads of Spike’s spunk. His shafts still bulged her stomach hugely, but her massive cum-gut now roiled and sloshed beneath her; her massive ass wobbled almost as much as her belly did. Some part of Spike’s mind wondered if she’d convert his cum to even more curves, even as she grew bigger and bigger. The thought brought another massive load to bear on Zecora’s over-stretched insides, with Spike groaning and growling as the euphoria of release overcame his mind.

By the time he’d finished, Zecora’s stomach was thoroughly blimped out. Her hands and feet just barely brushed the ground, reaching around the curve of her cum-fattened belly. It was only Spike’s even more massive size that let him cradle her rounded form beneath him; she might have been the size of her cottage, but Spike was now nearly twice that. She wheezed, groaning again as Spike pulled his cocks out of her. A massive flow of jizz burst from both holes, covering the ground with a thick, creamy white.

With a pair of utterly pleased groans; the pair flopped onto the ground. Spike plopped onto his back, his chest heaving. Zecora just rolled over onto her back, then grunted; her massive stomach pinned her to the soil. Below them, the earth rumbled and shook with the force of impact of the two oversexed giants.

Spike was panting, his broad chest rising and falling. His cum-soaked cocks twitched above his pecs, thoroughly and completely pleasured. With a groan, he turned his head to meet Zecora’s eyes.

She had both her hands around her massive belly, and was struggling to hold it in place. She caught his gaze and smirked helplessly. Then, without warning, she burst out laughing. Spike couldn’t help but follow suit—his deep, growl-like chuckles mixed with her rich, mirthful tones as the two boomed out across the Everfree.

Zecora was the first of the two to sober up. “I take it your lust has now dried? Are you, perhaps, satisfied?”

Spike groaned. He at least had to reach down now to feel his nuts—neither was the impossible size that it’d been before. They were still fairly fat, pushing his legs a bit apart, but at least he’d be able to walk. Or waddle. And at least he couldn’t feel them sloshing anymore.

“For now. I think,” he said. He felt lightheaded. His thoughts were swimming. Absentmindedly, he noticed that the cascade of his jizz that had poured out of Zecora’s ass seemed to have formed a new lake below them...

“It’s good to hear we’ve pleased your wood. I was beginning to fear we never would.” Zecora cracked a smile at him. Spike grinned back.

He snuggled up to her; his massive body was nearly twice the size of hers, but her cum-bloated belly made her almost a match for him in weight. On instinct alone, he curled his arms around her, one behind her shoulders, and one between her bust and belly. Her tits seemed surprisingly small now, resting on top of her gut as they now did. He wondered again if she’d digest his cum into larger, plumper curves.

“Thanks,” he said earnestly. “Really. For the help. I think I’ll be able to control myself a bit better now.”

“I must say, the pleasure was all mine.” Zecora winked at him, then slurped up a string of cum that had been dripping from her muzzle. “If I said anything else, it would certainly be a lie.”

“Heh. I definitely enjoyed myself too.” Spike blushed a bit; even at his massive size, there was still something of the awkward adolescent within him. “But, um… Zecora? Are we going to stay this size for good?”

Zecora’s answering chuckle tinged his ears red. “The potion will only last for a time,” she said. “Till passion’s complete—or till hours number nine.”

“Nine hours,” Spike mouthed.

“Our passion, it seems, has gone on for ages,” Zecora said. She smirked. “Unless, of course, your lust has more stages.”

Spike felt for his nutsack again. It did feel a little bit fuller than it had just a minute ago. He swallowed again. They were already so big. And yet—nine hours…

“M-maybe a little,” he rumbled. “Not right now. But…”

Zecora chuckled. “When one fucks a young mare, one tends to mate her. So tell me, dear spike—do you have plans later?”
