In what was now a usual occurrence, the sounds coming from Lucy's apartment were nothing short of amorous. Currently, the muscular blonde was in the midst of riding her boyfriend reverse-cowgirl style. As she slammed her large hips on his crotch, Natsu was pressing himself against his girlfriend's rippling back and kneading her breasts.
"Natsu...I'm so close! Keep going!"
"God, Lucy! You feel so good!"
And few minutes later, the two reached orgasmic bliss, the dragon-slayer coating the celestial maiden's insides with his seed. After cleaning themselves up, the two embraced each other for some well-deserved sleep, unaware that were being watched.
The next morning…
As Natsu started to wake up, he felt the deliciously familiar sensation of his member being sucked. He lazyly opened one eye and saw a large silhouette under the sheets.
"Mmmm...starting early, eh Lucy?" Natsu moaned.
"What are you talking about?"
The salmon-haired wizard turned and saw Lucy still laying next to him. It took a few minutes for their just woken-up brains to realize something was up. Natsu grabbed the sheets and tossed them off the bed, revealing the mysterious cock-sucker to be…
"JUVIA?!" The energetic couple yelled. Indeed, the blue-haired amazon was the one servicing Natsu's member.
"Good morning, Lucy. Natsu-Sama." Juvia replied with a smile. "Just give Juvia a few more minutes to finish up."
"What are you doing here?! And how the hell did you get in?!" Lucy asked. Granted, random Fairy Tail members breaking into her apartment wasn't an uncommon occurrence, but Juvia was usually not one to do so. Especially for this kind of reason.
"Um...Juvia may have...broken your doorknob." The water wizard begrudgingly admitted. Lucy looked and sure enough, her door was slightly opened with the doorknob pulled completely off.
'Well, that's a new one.' Lucy thought, only to hear her boyfriend moan again as Juvia continued to suck him off. "Hey!"
The blonde pushed Juvia off her boyfriend and glared at her, muscles tensed. "Just what do you think you're doing?"
"You said Juvia could become Natsu-sama's lover." The blue-haired amazon pouted.
"I said you could have him one night." Lucy stated. Natsu was going to say something, but his mind then registered that both Lucy and Juvia were naked. And the sight of two naked, muscular babes was slightly short-circuiting his brain. So he decided to see where this was going. "You had your night. Wasn't that enough?"
"...not really." Juvia said with a slight blush. "Ever since Juvia's lovely night with Natsu-sama, Juvia hasn't been satisfied. Juvia's tried several different toys and played with herself quite vigorously, but nothing comes close to the pleasure Natsu-sama gave her."
"Why didn't you just try asking someone out?" Natsu asked. "If they got any sense, I'm sure they'd jump at the chance."
"Juvia about that. But the only other dragon-slayers Juvia knows is Gajeel-kun, and he belongs to Levy. Sting and Rogue live too far away and Cobra's an outlaw. Besides, Juvia knows none of them can heat Juvia up like Natsu-sama."
The blue-haired beauty then turned to Natsu and performed a side-flex. "Natsu-sama, you wouldn't mind having another go with Juvia, would you?"
"Um...well…" Natsu said with sweat running down his face. While he would gladly say yes, Lucy's angry glare was a pretty strong deterrent, something which Juvia noticed.
"It seems the only one who has a problem with this is Lucy."
"You're damn right I do!" The blonde exclaimed, causing Juvia to sigh.
"Very well. Juvia knows what she has to do."
Suddenly, Juvia placed her hands on either side of Lucy's cheeks before closing in and kissing the blonde, much to the shock of both Lucy and Natsu. At first Lucy attempted to resist the sudden lip-lock with blue-haired beauty but then started to feel...nice. While Natsu's kisses were full of love, they could also be pretty heated and forceful. Juvia's kiss had a unique coolness about it, and was full of tender care. It didn't help that Juvia started pressing her muscular body against Lucy's own impressive physique. Soon enough, Lucy actually started to get into it and began to kiss Juvia back.
Natsu on the other hand, was absolutely stunned by what he was seeing. The sight of his buff girlfriend making out with an equally buff beauty was turning him on like never before. Large breasts against large breasts. Massive calves pushing against each other. Four biceps flexing as the two beauties embraced. If his cock got any harder, Natsu feared it would break.
After what felt like an eternity, Juvia removed her lips from Lucy's, a small web of drool in between them before Juvia wiped it away.
"Wow...that was...nice." The slightly mesmerised Lucy stated, causing Juvia to smile.
"Natsu-sama wasn't the only one to touch my heart that day. The fact that you were willing share your Muscle Candies and Natsu-sama's love showed me how truly kind you are." Juvia said before placing her hand on Lucy's calve, feeling ever contour of muscle. "And Juvia's not afraid to admit that you're incredibly sexy...Lucy-sama."
'W-Why did that turn me on?!' Lucy thought to herself, momentarily stunned by the water mage's recent advances. "I...I don't know, Juvia."
'Please say yes! Please say yes!' Natsu mentally begged. The thought of having two amazonian lovers only made him hornier to the point where he began to stroke himself.
"I see. Juvia just needs to seduce you more...thoroughly." Juvia whispered into Lucy's ear, making the buff blonde hold in a moan. With her free hand, Juvia created a water tendril that reached into Lucy's nightstand and pulled a familiar bag of candies. She then stepped back from Lucy and pulled out one of the Muscle Candies.
"Wait, Juvia, what are you…" Lucy began to ask while Natsu looked on intensely.
"Juvia and Lucy-sama are about the same size right now. So in order to seduce Lucy-sama, Juvia is going to need to be bigger than her." And with that, Juvia flung the Muscle Candy into her mouth and bit down. A few seconds later, Juvia felt the familiar spark from her first muscle growth, but this time, it felt even more intense. As her muscles began to shake, Juvia gazed at both Natsu and Lucy.
"Natsu-sama. Lucy-sama. Please watch as Juvia's body grows for you!" The blue-haired woman moaned. And soon enough, Juvia's body began to grow once more.
Pounds upon pounds of muscle bulged out from her frame. Her deltoids and biceps bulged until they were as large as her head. Two sets of abs formed on her stomach, giving her a massive ten-pack set. Her calves were almost like tree-trunks, thick with power and adding a few inches to her height. Even her breasts swelled up, going through at least three more cup sizes.
'Oh, god!' Juvia thought to herself as her body expanded for the second time, even growing a few feet in height. Her first growth session was a rush before, but this time, it was partically orgasmic. With each new expanse of muscle, Juvia felt her core becoming wetter and wetter. With one last burst, Juvia flexed every muscle in her body, moaning at the top of her lungs as she reached orgamic bliss.
In the aftermath of all this, Natsu and Lucy stared at Juvia, the two of them in awe of blue-haired woman's transformation. There was no question that Juvia was now the most muscular person in the guild, easily being twice as big as Elfman. Even with Juvia calming herself down and letting her muscles relax, they still looked titanic.
"Amazing." Lucy said out loud, wiping some of the drool from her mouth.
"That was one of the hottest things I've ever seen." Natsu whispered as felt himself almost ready to burst. Juvia then noticed the stares and smiled.
"So, Natsu-sama, Lucy-sama," Juvia said before flexing her colossal biceps to their full size. "Do you want to feel Juvia?"
"Yes…" Lucy said in an almost hypnotized trance.
"Oh god, yes!" Natsu exclaimed in excitement. The two walked towards Juvia and marveled at her massive physique.
"Wow. I can feel the power." Lucy said she felt up the taller woman's thirty-inch bicep.
"So thick." Natsu stated as rubbed his hands all over Juvia's wide back. Both of the actions only served to make the rain woman even hornier.
"So...has Juvia convinced you?" Juvia asked.
"Not just yet." Lucy said with a pervy smirk as she grabbed a muscle candy for herself and swallowed. And just like Juvia before her, Lucy's body began to explode with layers of new muscle. "Oh, god! This feels amazing!"
Every muscle of Lucy's body tripled in size. Her deltoids expanded to the size of medicine balls. Her back muscles grew thick like the largest stones. And like Juvia, Lucy's breasts also tripled in size until they were bigger than the Rain Woman's. With one final burst of muscle, Lucy let out a massive moan.
"Wow, you look amazing, Lucy-sama." Juvia said with a huge blush.
"You look awesome, Lucy!" Natsu exclaimed with glee. After calming down, Lucy began to experimentally flex her newly embiggened muscles.
"Alright, Juvia. Here's the rule; if we share Natsu, we gotta be the same size." The blonde said with a lusty smile.
"Thank you, Lucy-sama!" Juvia exclaimed with glee before the two titanic beauties kissed once more. After that liplock, the two looked at Natsu. In particular, his horny smile and his fully-erect member.
"What do you say we 'celebrate'?" Lucy whispered into Juvia's ear.
"Sounds wonderful." Juvia replied before the two broke apart and began to flex, their muscles pumping to near superhuman levels.
"So Natsu-sama…" Juvia began to say.
"Think you can handle both of us?" Lucy teased.
"Hell yeah! I'm all fired up now!" The salmon-haired man exclaimed with a perverted smile before leaping at the super heavyweight ladies, causing them to giggle.
Meanwhile, Mirajane was walking towards Lucy's apartment with the intent of returning a book the celestial maiden had lent her a few days ago. But when she reached the end of the hallway, she noticed Lucy's door was slightly ajar.
'Looks like Natsu broke in again.' Mirajane thought with a giggle. She was about enter the apartment until she heard the sounds of giggling and moaning. 'Sounds like they're having a good time.'
Feeling a little mischievous, the white-haired barmaid decided to take a peek inside. But what she saw made her jaw drop.
On the floor mat, Natsu was making out with Juvia, their hands grasping ever part of their lover, while Lucy licked the dragon-slayer's abs and stroked his dick. What surprised Mira even more than seeing the threesome was the size of Lucy and Juvia. They looked so huge. So powerful. So...sexy. And seeing Natsu in all of his glory was also a treat for her eyes.
Eventually, Juvia and Natsu's lips separated and Lucy ceased her licking. The two amazons decided to treat their lover and moved towards his throbbing erection. The blue-haired bombshell and the blonde beauty then grabbed their massive mammaries and then engulfed the dragon-slayer's cock in-between the two pairs.
"Holy shit." Natsu moaned out with a pleased smile as his member was surrounded by four massive mounds of softness.
"I think he likes it, Lucy-sama." Juvia said with a smile.
"Really? 'Cause he's seen nothing yet." Lucy said before the two began to rub their colossal tits all over their lover's erection. As Natsu continued to moan from this incredible boob job, Lucy and Juvia were also getting riled up. Not only did the heat from the salmon-haired man's cock begin to spread through their breasts, their nipples were also pushing and rubbing against each other. The two muscle bound beauties looked each other in the eyes and once began to liplock, all while they continued to give their lover one hell of a boob job.
'Holy crap, this is hot.' Mirajane thought to herself as she felt her nipples harden and panties begin to moisten. While the good girl side of Mira was telling her to look away and not touch herself in the hallway, it was quickly silenced by her inner she-devil telling her let loose and enjoy the show. As such, the white-haired beauty's right hand began to hike up her dress up to her soaking panties while her left hand when into her bra and began to tweak her nipple.
'Alright, you three…' Mira thought as she began to rub her womanhood through her panties. '...show me something good.'
"L-Lucy! J-Juvia!" Natsu groaned. "I'm gonna b-blow!"
Hearing that only gave the girls more incentive to increase their rubbing, using their huge extent of their colossal cleavage to squeeze every last drop from their boyfriend. And with one loud groan, Natsu exploded like a volcano, coating their faces and bosoms with his seed.
"You let out so much, Natsu-sama." Juvia stated as she began to lick up the white substance.
"Seems like someone's excited." Lucy said, noticing the salmon-haired man was still at full mast. And before Natsu could catch his breath, he saw Juvia place her massive legs on either side of his head.
"It's your turn to pleasure me and Lucy-sama now." Juvia said before sitting on her boyfriend's face. With a grin, Natsu took the hint and began to lick the buff blunette's soaked womanhood. As this happened, Lucy lifted herself over the salmon-haired man's dick, rubbing her pussy lips on his tip before impaling herself on it with a load moan.
"Looks like...our muscles...aren't the only thing...that's bigger today." Lucy moaned between each thrust, reveling in her boyfriend's cock spreading her insides open. From Mirajane's point of few, she could see Lucy's ever flexing back as she rode Natsu along Juvia's pleasured expression and bouncing breasts.
While the two had gotten used to incredible sensation of fucking over the past few weeks, Natsu and Lucy both felt a level of euphoria unlike anything before. Lucy's stronger muscles were able to clench her lover's dick like the tightest vice. And Natsu's enlarged member was reaching the deepest part of the blonde's womanhood. The accompaniment of Juvia's moans was icing on the cake.
"AHHHH!" Lucy moaned. If her muscles made her feel confident before, their new size made her feel like a queen. Every single contour of muscle in the blonde's body flexed as she grabbed her breasts and kneaded them.
After a few minutes of thrusting and licking, the three lovers reached their climax with Juvia spraying her love nectar all over Natsu's face and Natsu filling up Lucy with his sperm. At the same time, Mirajane had also reached her own climax, biting her lips to keep the three from hearing her moan.
'That felt so good.' The white-haired barmaid thought to herself as she caught her breath. She looked inside and saw the three entering another sexual position. This time, Juvia was on all fours, her large calves supporting her equally large butt. The buff blunette used her fingers to open up her dripping womanhood.
"Come on, Natsu-sama. Please give Juvia your huge cock." The rain woman pleaded. With a smirk, the dragon-slayer lined up his erection and thrusted into Juvia, causing the both of them to moan. The salmon-haired man then placed his hands on Juvia's glutes and began to move his hips, pistoning his cock in and out of the muscular beauty.
"YES!" Juvia moaned through a horny smile and dazed over expression. "Juvia's missed the feeling of Natsu-sama! Juvia feels so warm inside! Please, fuck Juvia as much as you want!"
"Wow, she's got quite the dirty mouth." Lucy said as she wrapped her bulging arms around Natsu, her massive breasts almost engulfing his head. As the salmon-haired man's hips slammed against the blunette's ass, he began to kiss his blonde girlfriend. Lucy then took one of Natsu's hands and moved it down her ten-pack abs and down to her cum-soaked pussy. Taking the hint, the dragon-slayer began to finger the blonde's muscular pussy, his essence dripping out of her and making her moan.
'Well, looks like they're gonna be at it for awhile.' Mirajane thought as wiped her hand off with a handkerchief. Since the barmaid still had things to do, she placed Lucy's book on her doorstep and began to walk away. Feeling relieved, Mirajane began to hum to herself. 'I can just ask Lucy and Juvia for all the juicy details later. But seriously, they were even hotter than...those two.'
"AHHH!" Juvia moaned, her face contorting in a lustful smile as her new lover fucked her from behind. With each hip thrust, the two felt their ecstasy raise higher and higher. Eventually, the blue-haired beefcake came, clenching Natsu's manhood until he coated her insides.
But the three were far from done as they got into a new position with Lucy laying on top of Juvia, both of them looking at Natsu with longing expressions. The dragon-slayer got behind Lucy, rubbing his tip on her folds before thrusting inside her again. With each thrust, the blonde's massive breasts and muscles moved and rubbed against the blunette under her.
After a few minutes of thrusting, Natsu slid out of Lucy and began to plow into Juvia. And after pleasuring the blue-haired bombshell for a bit, he slid out of Juvia and re-entered Lucy. This continued for awhile, the three absolutely consumed in pleasure. Eventually, instead of penetrating either of them, Natsu thrust his burning dick in-between Lucy and Juvia's slits. The two amazons began to moan in pleasure before they looked each other in the eyes and began to lock lips again.
And soon enough, the three reached a simultaneous climax with Natsu's load spraying all over Lucy and Juvia's abs and breasts. And they were far from done.
After several hours of fucking later…
"Oh my god! This is delicious!" Lucy said with glee as she ate from freshly cooked steak, Natsu agreeing through a full mouth, much to Juvia's delight.
"Juvia's happy you two like Juvia's cooking." The blue-haired muscle woman said, who was now clad in a new t-shirt, shorts and a pink apron. After their threesome, Juvia and Lucy realized that now their clothes wouldn't fit them anymore. During this discussion, Natsu recalled that Virgo used to be bigger than both of them (though as an ugly she-gorilla form), so maybe she had clothes that changed with her.
And thankfully, the pink-haired maid spirit did have clothing that could fit anysize, much to Lucy and Juvia's relief, the blonde-haired bombshell currently wearing a white t-shirt and pink shorts that fit her perfectly.
As the three continued their dinner, they then heard a knock on Lucy's door.
"I'll get it." Lucy said before walking towards her door. She opened it up and saw Levy holding the book Mirajane had left. "Oh, hey Levy. What's up?"
Levy said nothing as she looked up at Lucy, seemingly entranced by her massive muscles and chest.
"They're even bigger." She whispered before shaking her head. "Um, is Natsu here?"
"Ya, why?" Lucy asked before slightly narrowing her eyes. "You're not gonna say you like him too, right?"
"What?! No! I'm happy with Gajeel." The petite blunette replied, confused why Lucy would even ask her that. "I just need to ask him something about dragon-slayers."
"Oh, okay." The muscle bound blonde said before stepping away from the doorframe, letting her small friend in. Levy then saw the now bigger Juvia eating at the table with Natsu. After remembering the weird question Lucy asked, Levy started to piece things together. However, she decided to focus on asking Natsu her question.
"So, what do need, Levy?" Natsu asked, having heard the two with his hearing.
"Well...um…" The bookworm said, her face becoming slightly uncomfortable. "I gotta know...is the muscle loving just something you're into or do all dragon-slayers like lady muscles?"
"Eh?!" The threesome asked.
"What brought this on?" Juvia asked.
"Well, me and Gajeel have recently gotten...intimate." Levy said with blush.
"Good for you!" Lucy said with a smile.
"Ya, but...I get the feeling that Gajeel is always holding back." The Solid Script wizard said, a concerned look on her face. "It's like he's afraid of hurting me when we...you know."
Lucy understood that. She recalled how rough Natsu could be in bed, and was thankful her muscular physique could handle it. So someone as petite as Levy would probably be in absolute pain if her dragon-slayer lover let loose.
"So you wanted to know how we got so big, right?" Juvia asked as she flexed her massive bicep, getting a nod from the smaller blunette.
"But, I also wanted to confirm with Natsu. After all, the last thing I want to get big and turn Gajeel away."
"He wouldn't do that! Gajeel-kun's a big softie!" Juvia proclaimed as Natsu began thinking. He thought back to when Juvia first presented herself to him and his first time with Lucy. While he did find the two to be sexy as hell with their new muscles, he recalled how every instinct in his body told him to claim the two as his own.
"I think Gajeel's gonna be into it." Natsu said, getting the three women's attention. "Igneel told me that dragons naturally desire strong mates. I guess in human terms, that means ladies with powerful magic or big muscles. Just look at Laxus and Erza."
The three looked at Natsu like had just grown an extra head. "Seriously? You gals didn't know they were a thing?"
"No! Since when have they been a thing?!" Lucy cried out in shock.
"I think it was about after we got back from Tenrou." Natsu replied with a horrified look on face. "That's when they started smelling like each other. And when…"
"When what?" Juvia asked, the three women fully invested in this new revelation.
"I...might've accidentally seen them fucking in the woods at one point."
"Oh. My. God." Lucy replied, utterly floored by this.
"Hm. Juvia can kind of see it." The beefy blunette responded while Levy thought for a minute.
"Alright, I'll do it!" The Solid Script wizard said with a determined expression. "Lucy, Juvia, show me how you guys got so jacked!"
Lucy and Juvia giggled at the short woman's determination. As such, Lucy went and grabbed the jar of Muscle Candies. She then further explained to Levy that she should never eat more than one candy at once, least her magic go berserk.
"Thanks, Lu-chan!" Levy said, two wrapped muscle candies on in her pants pocket as she left.
"Goodluck, Levy!" Lucy said before turning to Natsu and Juvia. "So, Laxus and Erza, huh? Gotta admit, I kind of thought he and Mira were together."
"I know; it surprised me too." Natsu said before Juvia suddenly pressed her musclebound frame against the Fire Dragon-Slayer's.
"Well, love tends to bloom in unexpected places." The Rain Woman said, a loving smile on her face as she looked down at the grinning Natsu. Seeing those two so close and recalling all the talk of sex made Lucy grin, and she soon took off her top, revealing her ten pack, medicine ball-sized shoulder, and pec-supported breasts once more.
"Speaking of love, all that talk about sex has got me in the mood." Lucy moaned as she sensual stripped out of her shorts, leaving her in a pair of striped pink panties. Catching onto this, Juvia pushed Natsu onto Lucy's bed before removing her own clothing, her pale and bulging muscles fully exposed.
'I guess I'm not getting any sleep tonight.' Natsu thought with a perverted smile as his two titanic lovers approached the bed, their lust as obvious and clear as rippling physiques.
Back with Levy, the blunette felt her heart race, thinking about how her next time with Gajeel would be more...intense than ever before.
And she wasn't the only Fairy Tail girl with sex on the brain, for in her kitchen, Mirajane was brewing her own batch of muscle candies. As she stirred the ingredients inside the pot, the white-haired beauty thought about the two people who had managed to catch her heart. A cocky lighting dragon who had a secret soft side and a red-haired fairy queen who was the embodiment of strength and beauty.
Over the years, Mira felt guilty and perverted for being in love with two people. As such, she kept these feelings a secret, lest she start up a bunch of unnecessary drama and risk losing her friendship with both of them. Not helping matters was that, like Natsu, she had seen the two of them fucking hard on multiple occasions in secret, making her feel even dirtier.
But after seeing Lucy and Juvia having their way with Natsu, Mirajane realized that she didn't need to decide between her two loved ones. If she was strong enough, she could have them both. And while both of them were out of town on jobs, that only served to feed Mira's anticipation.
'Laxus. Erza.' The Take-Over wizard thought as she licked her lips. 'When you two get back, we're gonna have some fun.'
But those are stories for another time.
Author's Note: Yes, expect to see other stories for some beefy GaLe action as well as a Muscle a Trois between the three S-Class wizards. And don't worry, some other Fairy Tail beauties are gonna get pumped up to join Natsu's growing muscle harem soon enough!
