"Natsu!"

The pink-haired dragon slayer looked over his shoulder to see an agitated Lucy glaring at him. By now he was used to her outbursts so all he did was grin widely at her.

"Hey Lucy! How's it going?" He asked cheerfully while taking a bite out of the flames he was eating.

Lucy sighed to calm down as she prepared herself for a conversation with the dense dragon slayer. For an entire month she had been trying to get his attention in a romantic way. As irritating as he could be, the celestial spirit mage had somehow fallen for his charms, if that's what you could call them. He was rowdy, rude, obnoxious and loud but at the same time funny, loyal, strong and she had to admit he was quite handsome. His pink hair always looked so soft and fun to run her hands through.

It took her a lot of time to realize this but Lucy had finally accepted what her heart wanted. She had made up her mind and tried to get Natsu to notice her. Flirting hadn't worked since Natsu was incredible dense when it came to romance. Lucy had tried to wear outfits, perfume, body contact and even once showed a glimpse of cleavage when desperation struck her. However, Natsu still hadn't picked up on her hints and it was starting to frustrate her. None of her attempts to get him to notice her like she saw him had worked. Every scheme she had come up with had failed miserably.

"You llllllllllike him!"

Lucy could feel her anger growing as the sing-song tone of a certain blue cate echoed through her head. Happy's constant teasing hadn't done her any favors either, it continually annoyed her and reinforced her desperation.

She had never been insecure about herself when it came to love. Sure she hadn't had a lot of boyfriends but she knew she was good-looking. Her long, blonde hair was always taken care off, her figure was voluptuous in all the right places and she even had a good personality to match it. But somehow it wasn't enough to get the dragon slayer's attention. Lucy was starting to lose hope and thought that perhaps it would be best if she just flat out told him about her attraction to him.

So that's why she was here at the moment, to tell him about her affections.

"Oi, Lucy. You still there?" Natsu wondered out loud as he munched on his flames.

His comment snapped Lucy out of her thoughts and she could feel her cheeks warming up. She nodded slowly and crossed her arms under her bountiful breasts, causing the two to look bigger.

"Well, I was trying to get your attention for a minute and it was getting annoying." She huffed.

"Oh?" He hummed and blinked at her. "What's wrong then?"

Lucy gazed into his onyx eyes and found herself starting to blush. She was about to tell him but at that moment she chickened out and sighed again. She just couldn't muster up the courage to tell him.

"It's nothing. I just wanted to tell you that we should get a job soon." She said with a fake smile.

"Oh! Alright then. Probably for your rent right?" Natsu said, not noticing the fake smile that she wore. "Anything for you!"

His honesty struck her heart but she nodded with fake cheer.

"Thanks!" She said and quickly turned around.

Lucy looked over her shoulder as she walked and saw her love interest happily eat away. She sighed once more, this time in sadness, before she sat down on a barstool. The young mage grabbed herself a drink and began chugging down the beer gloomily. Lucy was getting depressed with how weak she felt. She couldn't even ask the guy that was almost always with her, even in her apartment, on a single date! The thought alone was enough for her to slam her head on the counter.

"It didn't work?"

Lucy groaned and looked up at a worried Mirajane. The white-haired beauty had been the one to propose she should just confess her feelings.

"I chickened out." Lucy replied. "It wouldn't work either way. Natsu is too dense to understand. He's always been the more physical one, but what to do if he doesn't like my looks?"

Mirajane pitied the saddened girl that had the misfortune of falling for Natsu. Everyone knew that Natsu wasn't the brightest one, just like Lucy said he was more the type that did physical work or learned things that way. Natsu probably knew what love was but mistook Lucy's advances for being a close buddy. Mirajane sympathized with the celestial spirit mage and thought of a possible solution.

"Maybe we should think about what kind of girl he likes." She pointed out.

Lucy looked up from her drink and asked, "Well, what is his type?"

"I don't know, but someone should. Why not ask Happy?" Mirajane told her. "He knows Natsu the best out of all of us."

"I doubt that the cat will help me willingly." Lucy deadpanned. "We're going to need a bribe."

"I might have a solution for that." Mirajane smirked as she spotted a certain blue cat drooling at the sight of sushi.

The demon mage had made some sushi for her family yesterday and had some leftovers, which she brought with her to the guild. Happy was gazing at it from the other side of the bar with stars in his eyes. Lucy sweatdropped as she saw the cat having fantasies and drooling over the counter. That cat's obsession with fish was a major issue.

"Oh Happy!" Mirajane sang lovely at the cat.

Happy blinked and looked up to see the S-class mage waving him over. A dilemma unfolded before him as he was forced to choose, keep watching that delicious sushi or see what Mira needed. The gears were turning at full speed in the cat's head but ultimately a yell from Lucy got him moving.

"Aye sir! What do you need?" Happy asked stiffly as he stood at attention.

Mira giggled while Lucy sighed in exasperation.

"Happy, we were wondering about what kind of girl Natsu likes." Mirajane told him calmly.

"Is someone not getting any attention?" Happy asked with a cruel smile as he gazed at Lucy.

Lucy felt her cheeks burn once more but this time it was a mix of embarrassment and anger. She snarled and glared at the cat, who quickly backed down.

"Happy, tell us and I'll let you eat the sushi." Mira smiled softly and unwrapped a whole package.

"Aye sir!" Happy cheered and stared at the fish with wide eyes in joy.

He was about to jump towards the food when a hand suddenly grabbed him by his tail. He looked around and saw a very irritated Lucy. Happy began sweating bullets as he quickly backed down.

"Ah, right." He said sheepishly. "So you want to know Natsu's type huh? Well, he likes strong women. You know, the kind that have a lot of strength with enough power to bend steel."

Both fairy tail women blinked at the cat's answer with wide eyes. Of all the answers that they'd expected, that certainly wasn't one of them. Both of them quickly conjured up images of women with large muscles that were similar to bodybuilders. Natsu was actually attracted to that kind of girls?

"But how?" Lucy asked in confusion. "Natsu prefers buff women?"

Happy nodded while drool dripped from his fangs. The cat was almost creating a river now.

"Natsu told me that." He said and took a bit from the sushi. "Oh, but he didn't want anyone to know. Since it's kinda weird."

"You betrayed his trust for a piece of sushi." Lucy deadpanned with a plain look.

Happy shrugged and said, "Sushi made by Mira." Before he flew away with the sushi.

"I never though Natsu was into that kind of girls." Mirajane commented as she tapped her chin in thought. "Then again, there was this one time when we were younger and he was always looking shyly at a traveler that visited sometimes. She had this fitness figure to her and he once asked if he could feel her arms. I remember her smiling and allowing it, also that he was very pleased with it. Before anyone could ask what it was about he got into a fight with Gray. We kind of forgot about it but he was somewhat depressed when she left Magnolia."

"So, if I want to get his attention I should start working out." Lucy commented before she grew depressed again. "But then I'd need to work out for so long before I'd even get to such a level. By then I'll be old and wrinkled."

Mirajane softly laughed at Lucy's dramatic comment and patted her shoulder reassuringly.

"Maybe not Lucy. You see, I think we have something in the library about this." She said as if she had reached an epiphany.

"We do?" Lucy asked perplexed.

Mira nodded in confirmation. She gestured for the blonde to follow as she left the bar.

More than interested with what the take-over mage was planning, Lucy quickly followed her but before she left she glanced one more time at her love interest. Natsu was lounging at one of the tables with Erza and Wendy, and she could see the confident smile on his face.

"Just wait for me Natsu. I'll win your heart." She thought to herself.

Mirajane and Lucy walked through the guild's hallways as they made their way towards the fairy tail library. It was rarely visited, mostly by Levy, but both she and Mirajane often came here for peace and relaxation. They entered the library and found it empty of life. Not even their resident bookworm, Levy, was present and that gave them enough privacy.

It was a very spacious room with many bookcases that were all filled to the brim with literature. Some of them were purely for relaxation and were about action, horror, adventure, comedy and even some were about romance. Lucy knew this all too well since she looked up for tips in these books for her little quest to win over Natsu. However, many were about magic itself. Whether it be about history of magic, lost magics and even forms of magic.

The eldest Strauss sibling led the blonde through one of the aisles, past the history section, towards the a secluded corner of the library. When they got there she tapped her chin again as she searched for a particular book. Her eyes scanned every book in the worn bookcase until she found an equally worn book with a green cover.

"There it is!" She announced and reached out to grab it.

Once she had it in her hands she placed it on a nearby stand so they could take a proper look at it. The book was dusty and the girls quickly realized that it was a very old book judging by how old the cover was. A fairy tail emblem was depicted on it and it looked as if the book had seen better days. There was no title nor any name of an author, only the emblem and a symbol for the human body.

"What is this book about?" Lucy asked curiously.

"Master once told me about a book written by the first master, Mavis herself, about potions to improve the body." Mirajane answered her as she opened the book.

Another layer of dust was launched as it opened, revealing yellow pages from how old they were. It was clear to them that the book had been written early in the first master's days as leader of the guild. Some pages were creased or the letters had faded somewhat but the book was still intact.

Mirajane quickly went through the pages as they sought for a solution to their little problem. They passed remedies for the skin, ointments to increase one's immune system, a potion that could supposedly remove wrinkles until they finally found what they were looking for.

"Here!" Lucy said and pointed at a page. "This one is about 'magic muscle candies' that are supposed to help gain muscle mass quickly."

"It says that we'll need a few ingredients and use them to create two potions. The first one needs to be poured into a special kind of dough. Once we've done that we must knead them into little balls before dipping them into the other potion that will harden after a while. If we complete these steps then we'll have MM candies that should help you in getting muscles mass." Mirajane explained as she read the page for them. "The ingredients are easy to get by, in fact I think we have them in storage. Making them sounds easy enough."

"Alright then." Lucy said determinedly and looked into her friend's eyes with passion.

"Let's do this. I'm going to get buff for Natsu so he'll finally notice me!"

….

A week later, Natsu found himself hanging around in Lucy's apartment. The dragon slayer was bored and since Happy was doing something with Carla, he had absolutely nothing to do. The guild hall was practically empty at the moment because almost everyone was out on a job or doing something private. Earlier that day Gray, Erza and Wendy had left for a job of their own while leaving him and Lucy behind. He was kind of bummed that they didn't take him with them but apparently it was a job with very specific conditions which was the cause why he couldn't come.

Natsu had walked through the town for some time but in the end he found nothing to do. He had already trained for today, the cause of why he was smelling a bit at the moment, and while Lucy wouldn't appreciate him just breaking in, especially while still smelling like he did a full workout, he wasn't exactly that worried. He knew that the blonde girl liked his company a lot and he enjoyed hers so ultimately it wouldn't be that much of a deal.

His scarf and jacket were lying on the nightstand as he sat on Lucy's bed. The window was still wide open from when he got inside and he relaxed as the cool wind blew against his bare abdomen. Feeling quite content, the young dragon slayer further dozed off as he enjoyed the soft mattress.

"Natsu?!"

Said fairy tail mage looked up to see a startled Lucy standing in the doorway. She was dressed in a black shirt and pink shorts that accentuated her curvaceous body, not that Natsu cared that much. While he did appreciate her looks, he thought she would look better with some muscle on her. Come to think of it, a Lucy with a toned fitness body was actually quite appealing to him. Natsu shook those thoughts away as he focused on the blonde mage.

"Hey Lucy!" Natsu greeted with a wide grin and waved her inside. "How're ya doing?"

"I'm doing fine." She replied with a sigh. "You broke through the window again, didn't you?"

"Yup." He confirmed while still grinning at her.

Lucy shook her head in exasperation but gave a small smile. She was used to him breaking into her home by now and wasn't that bothered anymore. In fact, she was actually quite glad that Natsu was here since her little project with Mirajane had been finally completed this morning.

The celestial spirit mage looked down to the small pouch which held numerous green candy balls. Mirajane had warned her not to take two at once or according to the book, her magic would be affected by it and create disastrous effects. Lucy knew better than to tempt fate even though it was a trait associated with fairy tail.

"Why are you half-naked?" She suddenly asked when it dawned on her that he wasn't wearing his jacket or scarf.

"I was feeling hot because of the training I did a while ago." Natsu explained as nothing was wrong .

But there was definitely something wrong. Lucy could feel her cheeks burning, her heart racing and her desire for the dragon slayer only increasing as she gazed at the toned body of her romantic interest. She had had plenty of opportunities to check him out but now he was actually here in her home, in her bed no less, displaying those nice abs of his.

"Oh god, why is he making it so hard for me!" She screamed internally.

"What do you got there?" Natsu asked, his finger pointing at the pouch.

Lucy quickly thought of an excuse and replied, "Women stuff."

"Oh, okay." Natsu responded as his curiosity instantly vaporized.

Lucy smirked to herself as she saw him place his head on the pillow again. Most men hardly wanted to know about women's items and this time it played to her favor.

"I'll be in the bathroom for a moment." She said as she walked away.

"Okay, see ya soon." He responded.

Before she actually entered the bathroom, she took one more look at him to appreciate what she saw. A faint scent suddenly reached her nose, its smell assaulting her senses as she realized that it was Natsu. He smelt like a campfire along with a musky scent that could only by a byproduct of his training.

Lucy quickly went inside the bathroom as she felt herself growing hotter and hotter. Natsu's presence was a surprise but very much welcome, especially with his manly scent and his toned body. In Lucy's eyes he was perfect. Maybe a bit rough, dense, loud and annoying at times but still perfect for her.

A moan escaped her mouth as desire began to overwhelm her. She could feel her core burning and her nipples hardening beneath her clothing as she thought about the fire mage of her dreams. He was no prince charming but he could drive her wild! Were it not for the thin walls she might have taken care of herself right here, right now, but she didn't want to make him suspect anything.

She looked down at the pouch and gazed upon the heap of small candy balls.

"Maybe this is my chance." She whispered as she realized something.

There was no one here to disturb them, no one to interfere and it was as good as any other time. She could confess her feelings at this very moment and make Natsu return those feelings once she took one of the pills. According to the book the results were instantaneous so why wait?

Her mind was made up.

Lucy gently grabbed one of the green candy balls and sniffed it first. It smelled like strawberries and a bit of vanilla, which made it a lot easier to take them. Determined to see this through, Lucy nodded to herself before she put the small MM candy inside her mouth. Her tongue touched the hard exterior of the candy before she bit down on it. The little orb proved no resistance and shattered beneath her teeth as its contents washed over her taste buds.

The effect struck like lightening.

Lucy groaned and buckled over as a wave of heat, energy and a small tinge of pain coursed through her. The feeling was quite intense, so much that it momentarily dazed her. The blonde girl could practically feel the change in her body as if her skin was stretching and her body rearranging itself.

Then out of nowhere her muscles actually began to expand! Lucy watched through almost closed eyes due to the pain as her shoulders pulsed and slowly expanded. Layers of muscle were added as her deltoids bulged outwards, making her shoulders wider. Her triceps expanded and soon resembled thick ropes while her forearms grew thicker with small veins popping up. Then her eyes landed on her biceps that inflated to a much larger size, one that made it look as if someone had stuffed large grapefruits under her skin. They didn't just look big but they were also very noticeable and so were the small veins that ran across her soft skin.

Lucy let another groan as the transformation continued and her body kept on adding more muscle. Her legs almost buckled beneath her as her calves started bulging outwards. They increased in size, so much even that they now had a smooth teardrop form. Her quadriceps grew as well, her thighs now more pronounced and thicker while they expanded. But getting wider wasn't the only thing that her leg muscles did, her legs themselves also got a bit longer, adding a few inches to her height. Lucy had always been proud of her assets and those included her round rump but as the muscle candy did its work she could feel it grow as well. The blonde's glutes swelled which made them not only rounder but also firmer.

The heat concentrated in her torso as the muscles there started growing. While she had a lean belly before she now sported a very noticeable set of abs. The small blocky muscles were very pronounced now, they were defined and wide plus if you inspected them closely you could see that the space between the abs was quite deep. The six-pack that she just gained was so majestic that most people in the gym could only attain it after dozens of hard workouts. Thick chords of muscle were visible on her back as they swelled in size and that was a good thing for her. The reason for that was because her pectorals grew outwards, widening to a much larger size to the point that a small line was visible between them. Of course if her breasts didn't obscure it. While it hadn't been mentioned in the book, her breasts seemed to swell as well, adding a cup or two in size which made them much heavier than they already were. If it wasn't for her stronger back she might have gotten an instantaneous ache in her back because of the weight.

Lucy let out a moan and a sigh as the pain faded away along with the intense feeling of her growth. All that she was left with was a new muscular body that most people could only get through hard work and dedication. As her breathing calmed down she fully opened her eyes and inspected her new form. She was sweaty from the experience and it showed as her brand new muscles glistened while her damp clothes stuck to her body. Speaking of clothes, she saw that her shorts had ripped somewhat to make place for her now impressive quads. The seams on the bottom were loose and it was straining to hold it together as her enlarged rump pressed into the material. Her shirt had survived as well but it had suffered its own share of damage. The piece of clothing now almost stuck to her torso like a second skin while exposing a lot more midriff than it previously did. Her short sleeves were slightly torn because of her bulging biceps and shoulders, but it had also ripped at the neck because of her pectorals and her much larger boobs.

"Wow." Lucy whispered astonished by the results. "I had never expected this much."

And indeed, it was a lot more than she and Mirajane had expected. Instead of a fitness figure she had gotten something that resembled the middle ground between that and an amateur bodybuilder. She wasn't exactly huge or anything like that but she still looked as if she spent a lot of time in the gym.

Lucy looked at herself in the mirror and tentatively flexed an arm. Slowly but steadily her bicep flared to life as an impressive peak was reached by the ball of pure muscle. The little veins danced beneath her skin as she maintained the flex. She would be lying if she said that she wasn't completely interested by the incredible biceps she now sported. It felt weird to be like this, but at the same time, it was actually not that bad. A part of her actually enjoyed being muscular. Lucy kept on exploring her new body until she remembered why she had done this.

"Alright girl, time to do this." She said as she gazed at her reflection. "You're going to go out there and claim that dragon slayer."

Maybe it was the muscles but she felt more confident now. She did one more checkup on herself before taking a deep breath and opening the bathroom door.

Natsu was dozing off in peace when she came back, he had obviously not heard the sounds she had made back in the bathroom when she had taken the candy. Lucy let her gaze wander as she checked him out while also slowly walking towards him. She had a mild blush on her face as perverted thoughts entered her mind about her and the fire mage.

"Natsu?" She spoke up trying to get him awake.

Natsu hummed and rubbed his eyes as he got up. He yawned loudly before blinking a few times.

"What's wrong Lucy?" He asked and turned around.

She would have almost laughed at the expression he made when he saw her. While still full with confidence, she was getting a bit shy with how his piercing gaze was settled on her.

"So, um, Natsu. Do you like the new me?" She asked softly and flexed her arm again.

His dark eyes trailed the bulging limb as it moved and Lucy was already relishing the attention she was receiving. Her inner self was screaming in joy, she was just so happy that he was focusing on her and her alone. He was quiet and still baffled for a few seconds before he suddenly grinned widely.

"Holy crap Lucy!" He exclaimed with wide eyes that shone with excitement. "You're so buff!"

The dragon slayer quickly jumped out of the bed and rushed towards her.

"Yeah, I was wondering how I could get your attention so I asked Happy what kind of girl you liked. I was a bit surprised at first but then me and Mira looked for a way for me to actually fulfill your standards." Lucy explained as he kept his attention on her. "I wanted to show how much I'm interested in being your girlfriend."

"Wait, you did this because you wanted to be my girlfriend?" Natsu asked with a confused look.

"Well, yes." Lucy stammered as her blush increased.

She was getting even more embarrassed now. However, instead of what she expected him to he just burst out laughing.

"Lucy, if you wanted to be in a relationship with me then you just needed to ask." Natsu told her as if she was being silly. "I like you too!"

"You mean it?" Lucy asked as her chest tightened and her stomach felt as if butterflies were flying inside of it.

"Of course. Don't get me wrong, I like the new you but the old you was fine as well." Natsu replied before greedily staring at her muscles. "But this rocks!"

She couldn't help but squeal loudly and before Natsu knew it he was enveloped in a hug by the blonde muscle girl. Lucy was giggling out loud while Natsu enjoyed feeling the girl's muscles pressed against his bare torso. Her strong and chiseled arms were nice to feel and her bountiful pec-supported breasts were pressing against his chest.

"I was so scared you'd reject me you big dummy!" Lucy said to him with a small pout.

Natsu grinned mischievously and leaned forward to capture her lips with his own. Lucy welcomed it and soon they were making out passionately. She could feel his warm body pressed against her own while their lips moved in tandem with each other. His wet tongue brushed against her lips demanding entrance which she gladly gave. Within moments they were battling with tongues, a battle of dominance that she lost but didn't mind all that much.

She let out a loud moan as his hands ran down her body, feeling her rock hard muscles and how soft her skin was. In response she ran a hand through his pink hair and enjoyed how it felt between her delicate fingers. Natsu snuck a hand down her back and groped her firm ass which caused the blonde to moan even louder. Pure lust and passion were clouding her mind but she didn't give a damn. After a long wait she finally got the affections of the man she wanted and it felt so damn good.

After some time they reluctantly parted. Both were panting hard as they had deprived themselves of much needed oxygen but neither cared too much about that.

Natsu grinned wildly before placing both of his hands on Lucy's large breasts. She let out a small squeal as she felt his warm hands on her mounds. The dragon slayer started kneading her bountiful boobs, his fingers were twirling her erect nipples beneath her straining shirt, and it drove her wild. Lucy was one big panting mess as Natsu kept teasing her. She could feel her core heating up and her panties getting utterly soaked.

"Natsu…" Lucy softly moaned as her wide legs rubbed against each other.

"What's the matter Lucy?" The pink haired mage whispered into her ear, his warm breath tickling her soft skin. "Is it getting too hot for you?"

Lucy moaned again as he guided her to the bed and pushed her down. She blushed fiercely as he pulled off her tattered shorts revealing her white panties. With a grin he slid a finger on the edge of her covered yet wet pussy lips making her squeal in ecstasy and surprise. Natsu enjoyed hearing her make such sounds for him and it motivated him to move on to her chest. He placed both hands on her shirt and with one quick grin he tore it away.

"Natsu!" Lucy squeaked and covered her chest with her massive arms. "Be careful!"

"Oh come on Lucy, admit you liked that." He replied teasingly as he got on to the bed as well. "Besides, I think you like it rough."

Lucy was already trembling from all the ministrations she received but now she was almost begging him to take here right here. He pushed away her hands and smiled as he gazed at the uncovered mounds of flesh that were her luscious boobs. They had indeed grown as well, larger than anything he had seen before. But he also looked at the immense pecs and the ripped abdomen of the blonde girl. He found himself being attracted to her hard abs.

"Now what do we have here?" He whispered as he crawled down to her pussy. "Looks like some kitty wants to play."

Lucy blushed fiercely as Natsu removed her panties, revealing her moist lips. He blew softly on them which caused Lucy to slightly tremble. The blonde couldn't comprehend how Natsu was so good at this especially considering Happy told her that he had never done this before. If so then he was a natural at this! She could feel her nerves burning and her arousal skyrocketing. Natsu then leaned in and began to 'eat her out' as people said. It was an overload of excitement for his female partner, she instinctively pulled him closer with her powerful arms as he licked with passion. They weren't even having the main act yet and she was already a moaning mess.

Sweat was pouring down her body, coursing through the crevices of her muscles. Thick drops were dripping down her abdominals while she moaned his name. Natsu on the other hand liked her taste and couldn't get enough, nor could he with her enormous thighs. He felt the girl's muscular legs clamp down on him with surprising strength but for him it was nothing. In fact, he liked it a lot.

"Oh, Natsu!" Lucy moaned loudly as her release came closer.

Sensing that she was about to cum, Natsu increased the ferocity of his administrations. His nimble tongue flickered all over her vaginal lips, his warm breath almost set her pussy on fire and with a final act of passion he nibbled on her clitoris. That was too much for the panting, muscular mess that Lucy was. She cried out in ecstasy while her juices rained down upon her dragon slayer boyfriend. Her thick thighs also clenched hard on the pink-haired mage who felt the pressure increase exponentially.

"That, that was amazing." Lucy panted, struggling for breath.

"And we're not done by a long shot." Natsu grinned as he licked the rest of her juices from his lips.

He quickly discarded his belt and began pulling down his pants, which made Lucy's heartbeat fasten. Her arousal was still at an all-time high but some part of her brain just screamed when she saw Natsu's manhood.

"Oh, my…" She whispered softly as her eyes widened at the sight.

Standing there, proudly presenting what he had by standing with crossed arms and a wide grin, was a completely nude Natsu. She could see everything, every scar, every muscle fiber and every detail of his body. Even his musk seemed to somehow get increased by stripping completely. Lucy could only stare in disbelief at the huge dick that Natsu had. It had to be at least 11 inches erect and even his balls were so big and full. Seeing that rod made Lucy feel warmer and more aroused than she already was, if that was even possible anymore.

"So, you ready Lucy?" Natsu said with a predatory grin.

He leaned down to her bigger body, running his hands up her muscular torso and giving her right breast a good squeeze before his cock stopped at the edge of her pussy. Her heartbeat was now louder than ever. Seeing, and even feeling, that big instrument pushing up to her was driving her wild with excitement and anticipation.

"Yes, yes I am." She declared and closed her eyes in preparation.

Natsu then finally inserted himself, pushing his formidable length inside her slowly. Lucy gasped as she felt him inside of her and not stopping. Once he had his entire length pushed inside of her, she could feel her walls stretched like never before. It was painful but luckily for her he let her adjust first. Eventually the pain subsided and was replaced by a rising amount of pleasure.

"I'm going to start now Lucy, damn you're tight." Natsu announced.

"Okay." Lucy whimpered as she felt him move his hips.

At first he went slow, he wasn't inconsiderate, and Lucy was grateful for that. If he didn't he would have split her in two with that beast of his. After a few thrusts every trace of pain was erased and instead she felt amazing. Natsu grunted as he picked up the pace and went harder. Moans of pleasure escaped Lucy's parted lips as pure bliss assaulted her mind.

"Yes, oh, yes!" She squealed in excitement and bliss.

Natsu's dick felt so hot inside of her, warming her up even more than she already was. Her bountiful breasts began moving as well like two giant marshmallows. The dragon slayer's thrusts were getting fiercer and he was showing just how great someone of his kind was when it came to sex. His hand latched onto her bicep, urging her to flex and she, as a slave to his desires, did just that. The blonde girl flexed her formidable bicep causing a firm mound of muscle to tense. Natsu greedily took it all in with hungry eyes.

"Damn Lucy, your muscles are awesome!" He cheered.

"They feel great as well!" She replied honestly.

Lucy used her improved strength to match his thrusts which led to even more pleasure for the pair. She could feel their moist bodies slam into each other, his lean one against her buff body. Natsu then slipped a hand beneath her to massage her firm yet exquisite butt. This made her moan even more while electricity ran through her spine. All this lust and pleasure was overloading her senses.

Natsu suddenly slowed down which confused her until he turned her around. Now she was laying on the bed on her belly while her ass dangled in the air. She looked over her broad shoulders and saw him grin before beginning his attack once more. She let out a loud yell as he penetrated her again. His balls were bouncing against her rump while his cock pumped inside of her. Lucy's broad, muscular back flexed as she writhed beneath him.

"Natsu, I'm going to cuuuuum!" She exclaimed and felt her juices spill out once more.

"I'm nowhere near done Lucy!" He replied to her.

"What!?" She asked with wide eyes. "If you keep this up I'll split!"

"Don't worry Lucy. I'll speed things up a little." He said with a grunt.

Without any warning he began to heat up as he went faster and faster by tapping into his dragon spirit. By now Lucy couldn't speak anymore because of all the fucking. He was going so fast! At that moment she realized that if she hadn't bulked up she wouldn't have been able to handle him.

Lucy started matching his rhythm and while she did that she fondled her breasts with her hands. Her tongue hung out of her mouth as she was pounded mercilessly by her amazing boyfriend. Every muscle in her body flexed while they went at it like rabbits. Her toned body was overloaded with pleasure and she was sure that Natsu was in heaven as well. The muscles in her vagina were clamping down hard on his large dick, trying to suck out every drip of cum he had.

As for Natsu, he was indeed in heaven. Lucy was so tight and her body was not only strong but hard with muscle as well. Those hard, shapely muscles beneath flawless skin were driving him wild. He could feel his release coming. Her tight walls were firmly wrapped around his aching cock, trying to squeeze the cum right out of him.

Natsu groaned as felt her up again, feeling those hard and big biceps of her. The small veins dotting her limbs were simply amazing. Sweat was pouring down every part of her body, running through the crevices of her chiseled abs. Her bountiful breasts were also delicious to taste and squeeze. Not to mention that muscular ass!

"I'm gonna cum, Lucy!" He yelled loudly, feeling his orgasm coming.

Lucy could only moan in response as he pounded her hard and fast to the point that she couldn't even speak anymore. The dragon slayer's stamina and strength was simply overpowering her.

He grunted and roared upon finally achieving his climax. His cum spurted out of his thick cock, burning and coating Lucy's core as he came. It was amazing just how much he could cum. It was only the first time yet he was already filling her up with his seed. He slowed down, panting all the while.

Their first session had certainly taken its toll on the two of them. Both were panting, gasping for air as their bodies were practically on fire, yet also grinning. It had totally been worth it, getting muscular so she could finally get Natsu to notice her. Lucy loved her new muscles, feeling sexy and strong with them. Obviously her new lover thought the same. Natsu was already rubbing her dense abs while caressing her inner thighs.

"So," He spoke up with that excited grin plastered on his face, "how about round two?"

Lucy grinned. Definitely worth it.
