The tables are turned on the usually-dominant Natsu during an impromptu training session with Erza. As if she wasn't terrifying enough already...

Erza had called Natsu out to the Magnolia fields and he reluctantly obliged, making his way there as quickly as possible. What did she want from him? Probably a lecture - but he hadn't destroyed anything or broken any rules in ages... Or so thought.

'Ah, you made it,' she said sternly once he arrived.

'Yep, what did I do this time?' Natsu asked, with a hint of worry in his voice.

'Hm?' Erza raised an eyebrow in confusion, 'Oh, don't worry, you didn't do anything wrong.'

Natsu sighed with relief, 'But then... What did you call me out here for?'

'Training,' the red-haired woman responded, 'I heard about your little problem and I thought some physical exertion might help clear your head.'

'What!? Who told you!?' Natsu yelled angrily, trying to think of who and why somebody would have told Erza of all people.

'Mira,' she answered.

'Huh? Who told Mira!?' he followed up.

'I don't know,' the older woman shrugged.

Natsu assumed it was Lucy. She was always running her mouth to Mira and Levy and god knows who else. Why couldn't girls just keep their damn mouths shut?

'So are you in or out?' Erza asked, staring Natsu down intently and giving him the impression she was implying something a lot more than a simple training session.

'In,' he said, licking his lips.

'Very well... REQUIP!' Erza transformed in to her Heaven's Wheel armour and lunged at Natsu with her sword.

Natsu barely dodged the attack but she quickly recovered and continued her assault, slashing her sword at him wildly. In an attempt to get at a distance from the sword mage, he jumped up high in the air and belted out a long stream of flames in her direction, completely engulfing her in fire.

When the blaze cleared, Erza stood firm, completely unfazed as she had transformed in to her Flame Empress armour just in time to nullify the attack.

'As predictable as always, Natsu,' she mocked the younger man, '...REQUIP!'

Now donning her powerful Purgatory armour, she lunged at Natsu once more, this time making a connection with her sword and sending him crashing in to the ground.

Natsu jumped back to his feet and eyed his teammate with a predatory glare. He usually found Erza terrifying when she was like this, but right now, all he could think was how hot she looked. He flared his fangs and pounced on the woman - but not to attack her. He grabbed her tightly by the waist and started kissing her.

Erza smacked him away and laughed, 'Is that your technique for wooing a woman? You need to work on your charm.'

Natsu growled and pounced on her again, this time groping her large breasts with his hot hands and squeezing them. Erza remained unimpressed and simply took hold of his wrists with her hands and pulled them away from her, crushing the salamander's arms with her strength.

'I don't think so,' she said coldly before kneeing him hard in between his legs, making him cry and crumble to the ground.

She gripped the boy by his pink hair and pulled him back up to his feet. He struggled under grasp, attempting to land another attack on his superior, but she simply raised her arm and backhanded him hard, sending him flying backwards and landing hard against the dirt floor.

Before he could get back up, Erza darted to where he had landed and pinned him against the ground with her foot, pressing hard against his groin and making him cry out in pain. She raised her sword and used it to masterfully slice up the fire wizard's vest and pants without making a scratch on his body.

'Fuck you, bitch,' Natsu spat.

Erza laughed in response, 'I believe it will be the other way round!'

The powerful wizard delivered another hard kick to the dragon slayer's nether regions and then stepped over him. She requipped in to a simple white dress that barely covered her chest and legs. She wore no underwear underneath so Natsu could see straight up to her cunt and felt hunger burn in his groin at the sight.

'You like what you see?' the female warrior asked and Natsu nodded excitedly, 'Then eat up!'

Erza sat down on Natsu's face, forcing her pussy in to the horny dragon's face. He started devouring it immediately, lapping at the folds and trying to work his eager tongue deep inside.

Erza moaned with satisfaction, 'Not bad, Natsu. At least you're good for something.'

She started rocking her hips gently, rubbing her moist pussy over Natsu's mouth and nose, teasing him as he tried to eat her out. With her thighs on either side of his head, she pushed them together, crushing him in between her strong legs and locking him in place.

Natsu moaned in to Erza's hot cunt as he was suffocated in between her thighs. The smell from her dripping pussy was filling his nose and driving him wild with desire. His cock was achingly hard and desperate for some attention.

'Come on Natsu,' Erza ordered, 'Finish me off!'

Natsu obliged, furiously fucking the red-haired woman's throbbing clit with his tongue until she screamed and her pussy contracted and exploded, shooting its juices in to the boy's waiting mouth. Erza tasted sweet like honey and Natsu ran his tongue all through her pussy to lap up as much of it as he possibly could.

'Good,' Erza commended once she stopped panting from her orgasm.

The knight looked around to Natsu's hard cock and smirked, 'What should we do next?'

Natsu moaned something beneath Erza's pussy but the words were muffled and indistinquishable.

'Do you want me to fuck your cock?' she asked, wrapping her hand around the throbbing member and squeezing it gently.

Natsu groaned and mumbled something else unrecognizable.

'Sorry, I can't hear you,' Erza said, removing herself from the pink-haired boy's face, 'What did you say?'

'Yes! Please!' Natsu cried shamelessly.

'Hmmm...' Erza smiled, thinking to herself, 'Maybe later.'

She released her grasp on the dragon's hot rod and instead flipped him over so that he was on all fours. She knelt behind him and slapped his ass, making him growl.

'...REQUIP!' she changed her outfit once again - this time shifting in to a tight black one-piece with a threatening-looking strap-on dildo attached.

'Nooo...' Natsu moaned, wriggling his ass to try and get away but Erza's grip was firm.

'Be a good boy and take it and I'll give you what you want,' she whispered in to his ear as she positioned the head of the fake cock at his entrance.

Natsu gave in and stopped struggling, trying to relax his body as he felt Erza push inside him, stretching his passage with her powerful "sword." Once the large cock was fully encased in his tight ass, Erza thrusted her hips back and forth, fucking the inferior wizard's pussy like a sex toy.

'It doesn't seem like this is your first time,' the warrior woman commented, noting how readily Natsu took the thick cock inside him, 'Who have you been fucked by before?'

Natsu didn't dignify the question with a response, just moaning instead as his rear was fucked brutally by the older woman.

'I asked you a question!' Erza snapped, grabbing the boy roughly by his hair and pulling his head back, 'Who else has fucked your pathetic submissive ass?'

'Gajeel...' Natsu admitted.

'Oh yeah... And how was that?' Erza asked

'Good,' the flame dragon smiled, remembering the sensation of being fucked by his fellow dragon slayer's mighty iron cock.

'Oh really? I never knew you were such a pussy...' the red-haired warrior teased as she continued to fuck her guildmate harder and faster, 'What's better - my cock or his?'

Natsu took a moment to say anything but then responded, 'His!'

Erza sneered, 'What was that?' she lowered her hand, wrapped it around the fire wizard's bursting ballsack and pulled hard, 'I think I misheard you!'

Natsu yelped in pain but didn't give in, 'I said Gajeel's! The cock of a real man is way better than your fake piece of plastic!'

'That's not the answer I was looking for, Natsu,' she said, squeezing his balls in her hand as hard as she possibly could, 'I'll only ask once more... Who's cock is better - mine or Gajeel's?'

Natsu growled, tears starting to form in his eyes as he felt like his balls were literally about to be ripped off, and broke, 'Yours! Your cock is the best, Erza! No man has anything you!'

Erza smiled in satisfaction, fucking the defeated wizard's ass a few more times before stopping and pulling out, 'Very good.'

She requipped back in to the white dress from earlier and turned Natsu over so that he was on his back again, 'Now, do you want your reward?' she asked, stroking his cock which was as hard as rock and leaking an extraordinary amount of pre-cum.

'Yes... Please...' the dragon slayer begged.

'Very well,' Erza spread out her hand and a small black ring materialized in her palm.

Natsu groaned in frustration, 'No... Don't...'

'I'm sorry,' Erza said in a sickingly sweet tone as she forced the cockring on to the boy writhing beneath her, 'But I want this to last and I don't trust you to not blow your load early.'

She positioned herself so that she was straddling the fire wizard and rocked her hips, rubbing her pussy against the younger man's cock.

Although he had already been defeated by the superior woman many times, Natsu still had some fire in him, 'I want to fuck your tight ass... Not your pathetic pussy.'

Erza laughed once more, 'Natsu, my poor dear, you don't deserve the ass,' she positioned herself so that her open vagina was just over top of Natsu's shaft, 'You will be fucked by my powerful pussy whether you like it or not!'

And with that, she slammed down on to his burning hot rod, capturing the dragon completely in her slick channel. Natsu shrieked as he was engulfed inside the tight heat. As she started to move her hips up and down, fucking the fire wizard's burning cock, he felt himself wanting to climax almost immediately but couldn't thanks to the ring. His balls ached in pain as cum welled up inside him, ready to explode.

Ecstacy washed over Erza as she rode Natsu's dick like a plaything, feverishly rubbing her clit as she did so. She moaned and groaned with pleasure and the noises drove Natsu wild.

'My pussy loves your cock, Natsu,' she declared, rolling her hips back and forth as she moved up and down to tease the victim of her fucking as much as possible.

'Yeah well my cock hates your pussy,' Natsu lied, trying his hardest not to give away any sign that he was even remotely enjoying Erza's torment.

As amazing as it felt, it was also pure torture on Natsu's desperate cock to be fucked like this. The tension in his balls was immense and the pain he felt mixed with the pleasurable sensation on his cock was so overwhelming he thought he might pass out. He wanted to cum so bad and started writhing against the ground in desperation.

'Oh yes!' Erza screamed as she brought herself to an incredible orgasm, the walls of her pussy clamping around the cock inside her, provoking Natsu further.

Once her climax was over though, she did not relent, continuing to ride the helpless fire dragon and draw out the torture even longer.

Natsu couldn't take any more and he started crying and begging for relase, 'Please! Please let me cum!'

Erza simply ignored him, flicking herself off with one and and playing with her large bouncing breasts with the other. It wasn't long before she felt herself coming to another orgasm.

'Ready for another one?' she taunted the abused man beneath her.

'Nooo...' Natsu whined like a woman.

Tears were streaming down his face and his head was spinning with lust as he felt Erza climax once more. Her vagina pulled and squeezed on his cock as she came around him.

This time, feeling complete, Erza stopped and pulled herself off of her teammate. His cock was purple and looked like it was about to burst which pleased the S-class wizard greatly.

'Please...' the fire wizard pleaded.

Erza continued to ignore him.

She stoop up and requipped back in to her normal outfit, 'Right, training is over. We're done here.'

She looked down at Natsu on the ground and gave his swollen cock and balls one last stomp with her foot before strutting off into the distance, leaving the younger man writhing against the ground, crying to himself.

Desperately, he flailed his hands at his throbbing member and pulled the cockring off. He barely touched himself for a couple of seconds before he was screaming and shooting the biggest load of his life. He covered his chest and stomach in seed as he blew load after load of hot, sticky cum. Once he was finished, he was still rock hard, his balls burning with pain, so he continued to jack himself off until he came yet again. He drenched himself in even more seed, moaning like a bitch as he did so and then fell back in to the ground.

His whole body ached and his head was dizzy. He could barely think but there was one thing that kept running through his mind. That bitch Erza had humiliated him for the last time. He didn't know when or how, but he would get his revenge.
