"Speaking"

'Thoughts'

Last time

"you know when I was sleeping I dreamt that Happy was running his hands over my body" this caused Erza's façade to crack but kept her calm as she was annoyed to be compared to Happy and relieved she won't be found out and just urge him to continue "and the creepy thing that Happy did was kiss me, but the weird thing is he doesn't take like fish but he taste sweet like strawberry cheesecake" was the last thing he said before he passed out from a blow to the gut delivered by Erza who by now has a very pronounce tick mark on her head.

"HEYYY ERZAAA!" Happy shouts as he saw both of them alright as he landed beside them and asked if Natsu was ok as he could see Natsu's soul hovering over his mouth.

"He's fine" she said a little angry as she removed Natsu and laid him of the floor and she stands up and requips her Heaven's wheel armor and flew off back to their friends leaving Happy to carry the unconscious Natsu.

"Stupid Natsu" she said to herself

Chapter 3: The Bet

"Are you ready to fight Erza? I'm gonna beat you this time and find out what's your problem" Natsu said as he began cracking his knuckles as Erza who seems a bit more of herself just stared at him and smiled a little.

"We'll see Natsu, well see but you haven't forgotten our bet then?" she asked as she stands up from the pile of lumber she's sitting at.

"Of course, I'm getting fired up" he said confidently

FLASHBACK

It's been an awkward week for Natsu and Erza since their victory against the phantomlord guild as everyone started to notice the strange behavior Erza is exhibiting such as avoiding Natsu for the first two days as she cannot stop herself from blushing and jumping the guy as she remembers her little episode with our hero, even forcing the guy to wear a shirt to somehow lessen her unwanted attraction to him. Though Natsu is a little adamant about it and even struck an argument with Erza who forced the issue by roughing Natsu up a little as he noticed that something was wrong with Erza but ignored it thinking that it was just her time of the month. The next day Natsu is now wearing a larger version of his old shirt which apparently Mirajane has made for Natsu saying that he would need it someday and that day was the day when Erza made him wear a shirt. Another change is seen with Erza as she could be seen walking while reading a book while blushing madly while distracted most of the time even bumping to people which continued up to the 5th day and as her friends started to get worried they asked their resident Specialist when it comes to the literary arts Levy who only gave vague answers by saying that she either didn't notice or make some lame excuse like 'she forgot her laundry' which she and her cronies would quickly leave to avoid further questions afraid for her well being, seeing that Erza just asked/made her promise to never reveal or tell what kind of books and novels she's been borrowing or there will be pain in the foreseeable future. And as this continues the members of team Natsu become more worried with her wellbeing and even asked for Lucy to ask what's she's been up to which failed miserably when Lucy returned shaking while telling them that there was nothing wrong with Erza trying to laugh it off and make light of it. On the sixth day this pattern still continues and somehow got a little worse as Erza was now blatantly avoiding Natsu to the point he almost forgot that there were five members of team Natsu as he didn't saw her for a whole day until later that day when he was walking back to Lucy's house which is unofficially team Natsu's HQ much to Lucy's chagrin. As he was about to turn to the corner he bump on to someone, somehow falling over somebody after he got his bearings and looked at the person he bump in to. He was looking at Erza's flush face which apparently is just centimeters from his while pinning her on the ground and not wearing her armor for a change.

"Hey Erza, where were you the whole day Lucy, Gray and Happy are worried about you?" he said still not lifting his face from Erza's causing his warm breath to wash over her face causing her to shiver and unconsciously lick her lips as if readying herself for a kiss that was about to come. Something she has read from the countless novels she's been vigilantly reading the last 4 days.

"I was just taking a walk" she said weakly and noticed the compromising position there in as Natsu's lithe form was pinning her to the ground his knees on either side of her thighs and both of his hands are on either side of her shoulders as racy thoughts started to enter her mind. Imagining that Natsu would just take her right then and there were she would try to fight back and he would overpower and start to kiss her and ravaged her waiting lips, then slowly trail kisses from her lips to her cheeks then nibbling on her ear lobe, trailing her jaw line with wet kisses to her neck nipping and licking up to her collarbone and finally landing to where he bit her. Kissing, licking and blowing on it while his hands fondle her breast while pressing his knees to her sex causing the small wet spot to grow and break the last of her resistance and let him do whatever he wants with her not caring who would see them causing her to moan unconsciously.

"Hey Erza are you sick or something?" Natsu asked concerned as he righted his self that he was now straddling Erza's waist while the back of his hands is pressed against her and his forehead respectively checking her temperature rousing Erza from her little dream. Realizing what was just running through her head. She forcefully shoved Natsu off her, stands up and tries to walk away ashamed and a little disappointed at the same time she could not think of any reason why she would be disappointed if Natsu didn't do what she was dreaming.

"Damn it" she hissed as she walks away when a hand grabbed her wrist. She was about to hit the person who touched her when she saw it was Natsu who by now is angry, unable to understand what's going on with her.

"What's your problem Erza?" he asked his voice raised a little causing her to flinch before she returned to her tough exterior. "You've been avoiding everyone these past few days they're worried about you! I'm worried about you!" he screamed the last part. "Were friends right? So why won't you tell me what's wrong" he whispered the last part.

Erza was a little shaken about Natsu's little outburst and glad knowing that he cares for her though her mood somehow darkened when he said they were friends and that somehow in the last couple of days she has developed a very strong attraction towards her male companion that she now discovered was lust and as far out as it would seem to her there was no mistaking it that she has started to lust after Natsu though she doesn't know why, all she knows is it's there and it won't go away and only intensifies as the days passed causing her to want more than just his friendship but, something more and from what she's been reading from the last 4 days. She wants to have a relationship with Natsu although it's leaning on a more physical than emotional aspect she doesn't care all she knows is that she wants him and after hearing him say they were just friends, she forcefully removed her wrist from his grip and started to walk away but Natsu didn't give up and blocked her path.

"Move Natsu" she said with a clearly visible threat behind her voice.

"No! I won't move until you tell me what your problem is" he said with a voice full of resolve causing Erza's frustrations to rise.

"Fine then I'll tell you if you can beat me" Natsu readies himself but Erza raised her hand. "We'll do it tomorrow afternoon in front of the guild, BUT… if you lose you'll follow anything that I say without questions asked" she finished and could see Natsu thinking and after a few seconds he nods his head and swears his gonna defeat her just so he could find out what's wrong with her and with that she left and immediately went to her home.

As she arrived she closed the door, leaned on it, slid down, and pondered the reasons of her sudden outburst after a few seconds of finding no answers to her questions, she stands up and went to her bathroom to take a cool shower to clear her mind of those thoughts that still plague her mind after their little accident and now she's sitting on edge of her bed wrapped only in a towel staring at the ceiling, at a loss on what's happening to her.

"Why did the thought of Natsu taking advantage of me entered my mind and what's worse I almost wished it was real" Erza said as she continues to stare at the same ceiling like waiting for it to answer her question. "I even challenge him to a fight that I know I would definitely win seeing as Natsu still needs some growing up to do" she lays down on the bed with her arm on her forehead.

"Natsu" she said his name with longing as the thoughts of their meeting came rushing back to her causing a knot to form in the pit of her stomach as she relieves those thoughts, her breathing became shallow and her body felt like its burning as a uncontrollable itch started to form in her sex, she sits up and took the book she was currently reading and read it as she started to imagine that the characters in the book was her and Natsu. Her free hand started to travel down south to her moistening sex and touched it causing her to stop as a jolt of pleasure run up her spine.

"I never knew it's this soft" Erza whispered recovering from the new sensation. She started slowly tracing her labia and another jolt ran through her body causing her to lie down on the bed as her towel unlatched itself from her curvaceous form as her breathing become ragged and sweat started forming over her body.

"Why am I doing this? Thinking of Natsu in such a way" Erza asked herself as her hand continues to trace her folds until her fingers hit a small nub on the top of her sex causing her to gasp from the increased amount of pleasure she received from just a glancing touch as her sex started releasing small amounts of her fluids, she continues her experiment spreading open her labia and running her middle finger along the length of her moistening sex, her juices started to flow at a steady rate and her pace becoming a little erratic as this was her first time doing such an act much less feeling an immense amount of lust toward the opposite sex. She continues tracing her slit changing the pace to find a way to quench the growing pit in her stomach biting her thumb while muttering Natsu's name every so often when a cold breeze swept inside her room causing her nipples to become painfully stiff making her moan in the process and she looks out the window towards the star filled skies, removing her hand looking at it glisten from her own juices and some form of reason came knocking back on her head.

"This is wrong" she said as another cold breeze came in and left her feeling cold as a thin sheen of sweat has already form all over her body causing her to notice the painful hardening of her nipple and the building heat from her sex as she lost all will to think and just went with her instincts.

'I know this is wrong' she gasp as she started her ministrations again 'but I can't stop, it just feels too good' she started to change her tactics and started to play with her clit as the pleasure increased she closed eyes savoring the pleasurable sensations she's feeling discarding the book her other hand was holding and started to play with her breast kneading and fondling it as her pleasure heightens and the knot in the pit of her stomach coils tighter. She began calling for his name loosing herself in the sensation and she accidentally slips a finger inside as her finger started thrusting and her other hand started to twist and tug on her hardened nipple.

'I'm sorry Natsu, my body won't listen to me… it just feels too good' she thought as another finger joined its sister thrusting inside her folds curling her fingers and managed to hit her g-spot causing her to screech and her ministrations rougher as her hips started thrusting in conjunction with her fingers splattering some of her juices of the bed.

"My hips won't stop moving… amazing…so good. Ahhh… Natsu" she gasped while continuing her ministrations as her pleasure filled mind envisioned Natsu over her body and his shaft was the one that was ravaging her sex as the mounting pressure in her sex becomes unbearable made her scream each time her fingers would go deeper.

"Something's coming… I'm cumming… NATSUUU!" she screamed at the top of her lungs as she experienced her first orgasm. Her body convulsed and went rigid as her sex flushed out a large quantity of her juices staining the bed causing the knot in the pit of her stomach to disappear. After coming down from her orgasm she looks out at the window again as a tear fell from her eye feeling completely ashamed at what she has done. Pleasuring herself with the image of a person she thought of as a brother even though she felt completely relaxed and the feeling of need towards Natsu lessen it didn't help the situation and as sleep slowly took over her she thought of what would happen if she wins against Natsu.

Next day Erza woke up smiling feeling strangely refresh and calm but as remembered what she just did last night put a frown upon her beautiful features she stands and went to her bathroom and washed her face looking at the mirror.

"I really did that last night, did I?" she looks at the stain on her bed sheets and sighs. "Now what will I do with the fight with Natsu? I can't just lose can I and tell everyone that I spend the rest of the week reading dirty novels and fantasizing about Natsu doing indecent things to me can I?" she looks again at the mirror another sigh escaping her lips "I guess I'll just have to make the most out of it and maybe I can get past this feeling and really fall for the idiot" saying that made her heart race and caused her to smile even a little and continues her morning ritual, though she was tempted to try and recapture the pleasure from last night's experiment but when the thought of using Natsu to get her off again caused her to shoot the thought down and went to get dressed and change the sheets of her bed. After having a quick breakfast she went outside of town to train and continue to test what her new armor is capable of.

After a whole morning of training she went back to the guild to help in its reconstruction after a few hours of work she sat down at Mirajane's makeshift bar to eat with Gray and Lucy as she returned to her old self as they chat.

"Something's change in you Erza" Makarov said as he paces back and forth looking at Erza with curiosity.

"What do you mean Master? If you're talking about this past few days I'm just distracted that's all" she said nonchalantly as she continues her lunch even though Makarov is still examining her. She froze when she felt his hand on her butt.

"Ahh… now I know you've become more mature than before. You're developing well, Erza my dear" Makarov said while laughing as Mirajane reprimanded him as he continues to laugh at his antics while he walks away.

'Something did change in Erza. She has become more powerful than before and if the person who manage to injure Jose was her then what could have caused this event to happen, for now I'll just watch' he thought as he continues his work rebuilding their guild and as the hours passed Erza continues to wait for Natsu sitting in a pile of lumber reading a book and after a few minutes Natsu arrived with Happy.

FLASHBACK END

"Hey Natsu do you have a death wish or something? You know you can't beat her right" Gray asked standing near Happy and Lucy.

"Shut up Gray, I'm gonna beat Erza! This time we won't be interrupted" he said as he and Erza walks outside.

"Master will Natsu be OK?" Mirajane asked Makarov also sensing the sudden increase in Erza's power worried for Natsu's wellbeing knowing that Erza never holds back on a fight.

"Don't worry too much Mirajane, that boy will be fine" Makarov calmly stated.

As the two separated looking at each other and sizing their opponents, Erza noticed that she's not that distracted anymore towards Natsu even though his back to his old clothes thinking of the reason why, she only came to one conclusion she needs to alleviate her sexual tension by doing it again. She inwardly sighs and focuses on the battle ahead.

"Are you ready Natsu?" she asked in a calm manner much like her normal self which caused Natsu to grin.

"So you're back to your old self again Erza, I guess a good night sleep is all you need" he said while cracking his knuckles.

"Prepare yourself Natsu, Re-equip" Erza is enveloped in pillar of fire shocking everyone who was there to watch, amazed at her show of power and the fact that it's the first time they saw her new armor though Makarov was baffled as to why he saw Natsu's seal overlapping with Erza's, while Natsu is just grinning waiting to see Erza's new armor. Suddenly the flames was split horizontally in the middle causing it to disappear revealing Erza's new armor to her comrades who stared wide eyed at the size of her new weapons and the sudden rise in her magic powers.

"Wow when did Erza get this powerful, and what with those weapons she could easily cut down a group of men and she's gonna fight Natsu with those" Lucy said as she just stares at Erza fearing for Natsu's safety.

"I don't know Lucy, she was powerful before, but now she could easily rival Laxus and Mystogan with ease, I just hope the fool know what his doing" Gray replied also eyeing the soon to be fight.

"Master did you see that?" Mirajane asked Makarov as she too also noticed Natsu's seal.

"I did Mira, but I don't know how. I guess I'll just have to start a research about it, and don't worry about those two though. Erza always go all out when it comes to battles but she won't do anything to endanger the life her comrades" he said.

"Nice armor Erza, what's it called?" Natsu asked casually but ready to attack at any moment.

"It's the Dragon Slayer's Armor, Natsu" she said as she too is prepared to attack.

"Nice name, it reminds me of someone" he said before he charged towards Erza who was still standing using his "Fire Dragon's Iron fist" and as he closes on Erza. She quickly raised her giant blade's flat side diagonally acting as a shield and the moment his fist connected with the blade the flames in his fist started to disappear and absorbed. He jumps back as Erza removes her blade and quickly saw his flames were being absorbed by Erza through the dragon head shaped shoulder guards.

"What happened, why did you absorbed my magic?" Natsu said pointing at Erza annoyed at the fact she just absorbed his flames. But Erza ignored him and charge at Natsu by jumping in the air and she spins towards Natsu with her weapons covered in flames causing her to look like a flaming buzz saw which immediately caught Natsu's attention as he jumps to the side to avoid. Erza's weapons hit the ground causing an explosion creating a crater as flames started to shoot forward appearing from the ground. Natsu continues to jump away from Erza when he was far enough the dust suddenly cleared as Erza is standing pointing her blade towards Natsu as a fireball forms at the tip of the blade before it was fired at his direction seeing there was not enough time to dodge he crossed his arms as the attack hits him.

Everybody was shocked at Erza's display of power and can feel the heat radiating from her thinking that Natsu was already beaten as some of them forgot the fact that Natsu was a Fire Dragon Slayer and was shocked to see the flames that surrounded Natsu was diverted to his mouth as he ate it.

"I thought as much" Erza said with a smile knowing that her assumptions were right.

"That was tasty Erza, though you should have known that fire won't work against me" Natsu said while wiping his mouth and patting his belly as he notices Erza doing the same move again.

"I know Natsu let's try my new theory then" she said calmly as she launched her attack while Natsu just waits for it to hit. That's when he noticed the fireball going closer to the ground before it was too late as it exploded in the ground in front of him showering him with debris from the explosion. Erza smiles and dashes towards the dust cloud that has formed over Natsu, inside the dust cloud Natsu was coughing from all dust around him and decided to blow it away with his "Fire Dragon's Roar" when he felt Erza's presence behind him and was launch out of the dust cloud from the blow that came from Erza's halberd. He efficiently flip in the air to land on his feet and retaliates with his "Fire Dragons Roar" noticing that it was more powerful than the last time as it heads toward Erza, but it was foiled yet again as Erza just cut through it and continued her course towards Natsu as the flames from his attack followed Erza as her armor continues to absorb it. She spun and kicked Natsu in the gut lifting him up in the air she immediately followed through her attack unleashibg five powerful thrust before she spun once again as the halberd's blade generated flames and thrusts it forward, but instead of piercing Natsu in the gut the flames from the halberd shot forward exploding on impact sending Natsu flying backwards before landing painfully on the ground.

"So do you give up Natsu?" Erza asked as she rights herself from her current position and looks at Natsu with pleading eyes saying to just give up.

"No!" he stood up coughing some blood. "No, I won't give up until you tell me what was bothering you these last few days"

"You know you'll have to beat me if you want to find out" she said hoping that it was good enough reason for him to stop as it pains her to hurt him.

"Then I guess you have my answer" he said as he prepares to attack which caused Erza to frown ever so slightly as she puts her mask back on.

"I guess I'll just have to incapacitate you to defeat you" she said as Natsu shot forward with his fist cocked back thinking that he would use the same attack again. She lifted her blade to block Natsu's fist as it was about to connect flames appeared from his elbow augmenting his attacks speed and strength as he hit the blade in an upward swing shocking Erza who was unable to get a good grip of her weapon as it was flung into the air backwards. Natsu follows up by spinning around and delivered a flame propelled kick to Erza's gut shocking her yet again but before she was thrown backward Natsu grabs her halberd causing her to release it leaving it in Natsu's hand as she was sent rolling onto the ground. After a few meters she used her hand to push herself off the ground landing beside her blade.

"That was a good move Natsu" Erza praised as she took her weapon with one hand lifting it with ease.

"I told I'm gonna beat you" Natsu exclaimed as he tries to lift the halberd off the ground. Erza just ruefully smiles while summoning the shields that orbits around her and used them to attack Natsu. They shot forward like a bullet as Natsu waits for them to come to his range, swinging the giant halberd and hitting one of the shields losing his balance in the process causing him to tilt towards the halberds direction as the second shield grazed his cheek as it embedded itself to the ground. Erza never bothered to recall her shields as she catapulted herself towards Natsu. Natsu saw Erza and immediately raised his weapon to block her. Erza began to twirl forward as her blade made contact with Natsu's weapon with each attack becoming faster, heavier and more accurate causing everyone to stare in awe at Erza's skill.

"Amazing it looks like Erza is dancing" Lucy said in awe as everybody just nods their agreement.

'This is bad' Natsu thought as his arms starts to give way and Erza saw this and used it to her advantage. Using the same technique that Natsu used against her as she twirls around for the final time swinging her blade upward propelled by flames as it connected with the Halberd with enough force to flung it upwards as both combatants was able to look each other in the eye before Erza spun around and kicks Natsu in the gut sending him flying towards the guilds construction supplies exploding in a cloud of dust. Erza easily caught the Halberd with her free hand.

"Time to end this Natsu!" Erza shouts as she threw her blade upward its tip pointing at the sky as she spun around with her halberd. Its pole connected to the back of the blade causing the eye on the dragon's head to glow, the halberds lustrous gold started to spread to the blade as the transformation ends. Erza is now wielding a giant golden spear with one hand as she prepares to throw the weapon.

"Master I think we should stop this" Mirajane said worried for Natsu from the sudden rise of power coming from Erza.

"Don't worry like I said she knows what's she's doing" Makarov said as his eyes was glued to the scene.

"Lustrous Fang" Erza shouts as both her and Natsu's magic seal appeared behind her and wings made of fire grew from her back as she threw the giant flaming spear carving a path towards Natsu. Natsu saw the attack and braced himself from the explosion as it made contact creating a huge fire ball from where Natsu stood.

"Don't worry everyone he's still alive" Erza said calmly until they heard a roar coming from the direction of the explosion and moments later Natsu shot out from the cloud of smoke in his hands was Erza's spear. As Natsu was within striking distance, he swung the weapon with all the remaining strength he has but just as the weapon would made contact it vanished from his hands giving enough time for Erza to give him one powerful blow to the gut. He was about to fall to the ground when he was caught by Erza wrapping her arms around him enjoying the feeling of closeness between them.

"Looks like I won" she whispered to him as she continues to support him.

"Cheater" he said pointing the fact that Erza un-summoned her weapon to avoid which just caused her to laugh a little and made him smile before he passed out as all of their members came running towards them. She looks at the setting sun thinking that she might be able to get this to work.
