Gray let out a load moan with his eyes still closed. The bulge in his trousers was unmistakable. Becca grinned one last time in Natsu's direction and then turned to Gray, who was starting to rut his hips upwards, letting out frustrated sounds when he didn't find anything besides his own pants to rub against.

"Good morning, darling."

Gray finally opened his eyes and focused them on Becca. They were heavy with lust.

"GRAY," Natsu shouted with barely restrained anger. This bitch would pay for what she'd done.

Gray turned his face to Natsu and when their eyes met, his hips bucked upwards again and a long moan escaped his parted lips.

"Nah- tsu..."

"Gray, she drugged you! Don't let that bitch get what she wants! Please, fight it, I beg you!"

"H- hel- help me-"

Becca grinned mischievously and kneeled down in front of Gray. She stretched out her hands and ran her fingers slowly over Gray's heated cheeks, ignoring the angry growl from behind her.

"Oh darling, he can't help you. I rendered him useless. Just like you. Your cuffs are magic-sealing ones, so you can't defend yourself either. You're at my mercy," she stated with a cold voice. "Fun, isn't it?"

Gray finally tore his gaze away from Natsu and eyed the woman before him instead. She had started lewdly licking at his face while caressing his cheeks with her slender fingers.

Then everything seemed to happen at once. Gray snapped his knee upwards and hit Becca hard on the underside of her jaw, causing her to bite her own tongue strong enough to draw blood. Becca screamed in agony and pulled away; Gray's body shuddered with disgust. Then a female voice called something from upstairs and a few seconds later a woman - Natsu recognized her: she was the waitress who had served them their cocktails - appeared at the landing of the stairs.

All eyes were on the waitress, who looked taken aback by the scene unfolding before her eyes, but she caught herself after some seconds.

"Becca, the two female mages regained consciousness about a minute ago. They're causing a ruckus up there, demanding somebody tell them where their friends are. I thought you'd take care of all of them; at least that's what you said," she demanded, not showing any sign of consideration for the pained whine and the blood dripping from Becca's mouth.

Becca winced but took a deep breath and answered, her tone a mixture of anger, pain, and disappointment.

"I've... changed my plan spontaneously. Why didn't you lock the two females away? Surely somebody must've noticed that they passed out in the club?" She spoke with a lisp, seeing as speaking probably caused her pain now. Good, Natsu thought. Though taken the previous actions of her into account, he'd have liked it much more to see her tongue truly severed from the rest of her body.

"They passed out on the toilets, both of them. Nobody noticed. And you should tell us when you change your plan."

Becca grit her teeth. "I didn't have the time to tell you, I thought you lot would just this once use your brain the way it's meant to be used! Didn't you see me taking only the male one? I even left the cat there, did really nobody notice that?"

The waitress narrowed her eyes. "Was there any need to pay attention? You're the great Becca after all, you know what you're doing and nobody else can understand your actions anyway, so there's no need to tell us stupid folks the circumstances!"

Her voice dripped of venom and she took several steps towards Becca, her posture showing just how much she loathed her. Becca flinched and tried to bring more distance between them by crawling away, but once her back hit the wall, the waitress towered over her, her clenched fists pushed into either side of her waist.

"Don't think that just because you're the daughter of the two most powerful people in this town and our boss that you can do whatever you want! You promised to never harm anybody and now look at those two! I always knew one day you'd stop playing by the rules!"

"Talking about my parents, huh? Did you know that my father's no longer alive? And did you know that this pink haired mage over there killed him?" She nodded her head towards Natsu.

"What! I didn't kill your father! I don't even know who your father is."

"Did you forget Jackal? The explosion mage? The one you killed?"

Of course Natsu remembered him. But he hadn't killed him. Probably she hadn't heard of his revival and his battle with Lucy. How, he had no idea. But he wasn't going to mention that and put the blame on Lucy. He growled. "He killed himself after I defeated him! He tried to make the whole town and all its inhabitants explode! If it wasn't for this courageous cat here-" he made a gesture towards the still unconscious Happy- "there would've been many, many more dead people than just your father!"

The waitress looked briefly to Natsu, then back at Becca. "Damn right, Becca. He wasn't a good man and you know it. Powerful, but evil. He deserved to die."

"This fire bastard deserves to die as well! He should've died with him! He can be happy that I didn't kill him yet," she spat out. A shadow crossed her face and her expression changed from angry to defeated. "Go away, Jessy. There's nothing you can do to help them." Becca's voice wasn't steadfast any longer; it sounded pathetic and broken. Jessy's words had truly hurt her, Natsu noticed. Maybe she had hoped Jessy would be her accomplice.

"Oh, you bet," Jessy spat out and kicked Becca in the face, causing her to whine, slide off the wall and collapse on the floor.

Jessy whirled around and took in the sight of Gray, whose face and neck were flushed. A thin layer of sweat covered his temples and he panted. Natsu didn't know exactly how strong the drugs were, but considering how Gray had behaved shortly after waking up, it had to have been strong. He had neither moved his hips since kicking Becca nor moaned or showed any sign of arousal and the pain in his eyes was obvious. He was struggling very hard and Natsu was proud of him. If this bitch tried to do as much as touch him, he was going to take vengeance. Hell, she already had licked him. His level of anger rose dangerously.

Jessy turned towards Natsu.

"Do you know what exactly she was planning?"

Natsu had a hard time keeping his anger in check, trying to suppress entering Dragon Force. It took him a few seconds until he registered that the question was directed at him and that it was expected he provide an answer.

"Rape," he managed to choke out and a new, stronger wave of anger rolled through him like liquid fire, claiming control over his body. He saw scales forming on his forearms and felt strong magic pulse through his body, making him feel light-headed and positively drunk on power.

He didn't notice that Becca had gotten back to her feet or that she was closing in on Jessy. Only when Becca kicked her in her back and Jessy stumbled forward did he notice what was going on. His transformation was now complete; his focus was sharp and his senses even sharper than they usually were. His sharp canines were aching.

Jessy regained balance immediately and turned around, taking up a professional looking fighting stance. She didn't hesitate; she shot forward in one swift motion and landed her fist in the middle of Becca's face. Natsu felt deep satisfaction at the cracking sound of her nose breaking and her body hitting the floor. This time she didn't whine. She was getting angry again, Natsu could sense it. He tried to attack her as well but the magical cage sent painful jolts of electricity through his frame where he touched the walls and he fell to the floor once more. He rammed his fist into the floor in a fit of sheer anger and frustration at not being able to join the fight and being forced to watch. The impact broke the floor under his feet and Natsu found himself standing on big tarred chunks.

Becca smiled up at Jessy despite having suffered a big blow. "You'd better leave right now or I'll-"

"You'll what? You have no power over me. Your magic can only hurt mages and is completely useless against us normal people."

"-hurt him," Becca finished as if Jessy hadn't spoken at all and then suddenly Natsu felt as if the air was knocked out of his lungs and his body was being compressed from the outside. The pain that came with this was overwhelming. He screamed and nearly lost consciousness, but it was over as suddenly as it had begun. He lay coiled up on the now uneven floor, his eyes glassy and his body shaking from the aftermath of the pain. When he looked up again, Jessy was on all fours, her head bent forward obediently and Becca was retreating to the back of the room.

"Stay like this, don't you dare to look up or I'll hurt him again. It could even kill him, who knows?"

Becca picked up a metal rod and strode over to Jessy.

"JESSY! WATCH OUT!" Natsu shouted, but a moment later the pain was back and he screamed even louder than the previous time because the level of pain had increased - it was unbearable, even for a Dragon Slayer.

The pain subsided again after a few seconds and when Natsu's vision cleared, Jessy was lying on the floor in a puddle of her own blood, the scent of blood so prominent in the air that it overlaid everything else for a second. Then he noticed Becca walking towards Gray with a hungry smile.

Something in Natsu short-circuited and he picked up the largest chunk of tar and threw it at her with all the strength he could muster. It hit her spine and he heard another nasty crack. She collapsed on the spot, this time really unconscious or maybe even dead - Natsu didn't give a damn right this instant.

The only two things on his mind right now were Jessy, who had probably saved his life by possibly sacrificing hers, and Gray. He hadn't noticed that he'd started to move towards the both of them until Erza was standing right in front of him, effectively blocking his way. When exactly had she arrived? He tried to round her but she was right there again, blocking his way again. He reached for her wrist to push her aside but she was faster; his face met the floor and his arms were restrained behind his back before he even had the chance to do as much as blink.

"Calm the fuck down, Natsu! What happened here? Why are you in Dragon Force? Why are there two dead women here and why is Gray handcuffed? Explain! And quit Dragon Force!"

The only thing he could manage was a broken "not dead" and the moment the words left his mouth he noticed that it was true - he could still hear the hearts of the two women beating, though Jessy's heart was weakening by the minute. She was losing too much blood and she needed help right now.

"Oh god! Lucy! Call a healer! Now!" Erza ordered and Natsu heard Lucy rushing up the stairs. He hadn't noticed Lucy's approach at all. Had she come with Erza?

The grip on his wrists didn't ease. "Quit Dragon Force, Natsu."

"Let go. I need to stop her blood flow right now. Let go."

"I thought you were heading for Gray. You looked like you'd want to eat him alive, Natsu. I don't want you to hurt anyone. You scare me, frankly."

"I'd rather die than hurt Gray. Listen, this blonde woman is our enemy, she drugged Gray to rape him and the brunette is our friend. The blonde hit the brunette and I hit the blonde. They're both alive but the brunette needs my help now."

He swore to himself that if Erza didn't release him within three seconds he was going to make her release him. She wasn't as strong as him when he was in Dragon Force.

He didn't even start the mental count when she released his wrists and got off him. He quickly darted his eyes over Gray's frame to make sure he was alright - except for the obvious - and kneeled down next to Jessy. He examined the back of her head. She had a laceration somewhere in her bloody hair and he needed to find it. When he located the wound, he heated up his fingertips so he could carefully cauterize the veins.

He'd finished his job just when Lucy came back and told them that a healer would be arriving in some minutes. Jessy's life was no longer in danger now. Nothing could hold Natsu back anymore.

He slid over to Gray in a split second, uncaring of all the blood on his hands or on his clothes, and melted the chains that connected the metal cuffs to the wall. He couldn't destroy the cuffs; they'd need them again soon after all. He knew exactly where the key was, he'd heard keys clinking in Becca's pocket before. He scrambled over to her unconscious body and retrieved the key ring from her pocket. He tried out some of them, too far gone to logically think about which one would be the one that fit into the cuffs and after a few seconds he found the right one. He made a quick job of freeing Gray's wrists, and then he fused the chains together so that there were only four chain links between the handcuffs. He threw them at Erza together with the key and bellowed an order to handcuff Becca with them and then his hands were roaming over Gray's body to make sure nothing was broken.

Gray groaned and writhed under his touch and Lucy couldn't do as much as say "What's wrong with-" when Gray shouted and shivered and Natsu could smell that he was coming in his pants. He hadn't even touched anywhere near Gray's crotch. Natsu blushed furiously and hoped that Erza hadn't understood what had happened just in front of her eyes. Gray's cheeks were pink and he was panting and clawing at Natsu's shoulders like a lifeline. The ache in Natsu's canines was increasing by the second and Natsu didn't know what that meant -

But then another flash of pictures flooded his mind and made his vision black out momentarily - and he understood. His instinct of protecting and claiming had been triggered. He wouldn't be able to quit Dragon Force until the danger was over and he'd made Gray truly his. He was achingly hard in his own trousers, probably had been for quite some time already.

Shit, he needed to get out of here, and quickly. He glanced over his shoulder and found Erza and Lucy staring at him and shrieking when their eyes met his.

"N- Natsu, what's going on?" Lucy demanded with a shaky voice.

Gathering all his self-control, he pressed out a "He'll be okay, I'll take care of him" and lifted Gray up, using his body to shield his crotch from the view of the two girls. Gray's body fluids hadn't yet soaked through the fabric of his trousers, so there was nothing to see for Erza and Lucy either. He made for the stairs but Erza blocked his way again. He bared his teeth at her.

"Seriously, you look like a wild animal. How about you calm down here before you run off with Gray?"

Natsu growled, but Erza didn't back off.

"Get out of my way if you don't want me to claim Gray right in front of you." Gray let out a moan and Natsu's instincts were screaming at him to look at his mate, to kiss him, to bite him, to undress him- but he managed to keep his eyes on Erza, glaring daggers at her.

Erza's face showed that she didn't understand. "What do you mean by that?"

"What I mean is-" he leaned in close to Erza's ear, but didn't lower his volume so that everyone in this room could hear him- "that I'm going to have s e x with Gray. If you don't mind, would you please step aside now?"

Erza flushed brightly and was pulled away by an equally blushed Lucy before she could make any move.

Natsu was out of the building and on the way to their hotel in a flash, completely ignoring all the concerned people around them. He didn't take the usual route; instead he went for jumping over the rooftops. He figured it was the quickest way.

When Natsu was sure they were already halfway there, Gray started pulling at his collar and demanding attention.

"Natsu... please, put me down, I need- ahh- release."

"Just hold it a bit longer; I'm sure we'll reach the hotel in one minute-"

"It hurts, Natsu, please, now."

Gray being in pain wasn't an option, so he gave in a few blocks away from their hotel. He set him down on the flat roof carefully and leaned down to devour his mouth. Gray moaned and writhed underneath him and Natsu didn't need to do more than rub his hand over Gray's crotch a few times to make to make him come for the second time since he'd been abducted. His canines really hurt while Gray was shuddering through his orgasm, but he'd spare this for later, for when they were truly having sex.

"Natsu... do you even realize how you're looking at me?" Gray asked after his breath had calmed down a bit.

Natsu tore his eyes away and quickly picked up his still shivering Gray before answering, "no idea what you're talking about."

Gray let out a small chuckle and clung to Natsu as he brought them quickly to their hotel room, ignoring the stunned expression of the woman at the reception.

Once he'd reached the bathroom, he let Gray down on the edge of the bathtub.

"Geez, Gray, you really like to come in your pants, don't you."

Gray blushed heavily and looked away, but Natsu cupped his chin and made him look into his eyes again.

"I like it. That I can make you come this easily. I really turn you on that much, huh?"

"If you keep talking like that and keep looking at me like that, I might come again just from that... Shit, Natsu, just look at your face."

He was curious, so he let go of Gray and stepped in front of the mirror. He was startled to see himself in Dragon Force, with red eyes and scales partly covering his face. It would've been gruesome to look at, if his eyes didn't have that certain expression in them. It vanished after the initial shock but he'd definitely seen it. There'd been raw desire and burning lust in his eyes.

Natsu turned back to Gray, who was still sitting motionless on the bathtub, watching Natsu intently. With a few quick steps, he was in front of Gray again. He leaned down and nibbled at Gray's earlobe while whispering, "Let's get you out of these clothes."

Gray shivered and moaned at that, but complied eagerly. He stood up and helped Natsu undress with undressing him. When he stepped out of his drenched pants and saw the mess he'd made of himself, he blushed even darker.

Natsu was magically drawn to the smell of his release and before he noticed what he was about to do, his nose was already only half a centimeter away from Gray's erect penis. Damn, just how short could his refractory period possibly be? Was it because of the drugs? Probably. Natsu stuck out his tongue and licked a small stripe across Gray's frenulum and then pulled back again.

"You should probably take a shower," he winked.

"Sh- shower, yes. Okay." Gray stumbled towards the shower and clumsily let himself into the shower cabin. A second later the water was turned on.

Natsu looked down at himself. He'd probably been hard since he'd entered Dragon Force even if he hadn't paid it any attention at the beginning. It was starting to hurt and demand attention rather badly. But he'd sworn to himself he'd do this properly, with proper cleaning and preparation beforehand. His body's needs would have to step back a little while longer.

Natsu shed his clothes in a matter of seconds and entered the bathtub. He hadn't really thought about how he was going to clean his insides but he knew that he had to - there was no way he was going to let Gray stick his fingers or his dick inside his dirty hole. He got on all fours inside the bathtub and stuck his butt up, then took the shower head and turned the water on. He fumbled awkwardly with it until the jet of water was directed at his ass, but then noticed that he'd need to do much more than that to get the water inside. So he supported the weight of his torso on his shoulders and brought the other hand to his ass and pulled his cheeks a bit apart. The feeling of water hitting his entrance was odd, but he guessed he'd get used to it, so he just waited for some seconds.

Natsu jumped when Gray spoke again, "Need help with that?" He was leaning seductively against the sink and his fingers were lewdly playing with a small ice cube. His hair was damp and sticking out in all directions and his face was pure sex. Natsu choked on his saliva and dropped the shower head, then shrieked when he heard it hit the bathtub and fumbled to pick it up again. He could feel the burning heat in his cheeks. Gray let out a chuckle. He took the shower head from Natsu's hands and turned off the water. "I have a much better idea."

Natsu gulped; it was all he could do not to moan at the prospect of an ice cube inside his ass.

"Let's move to the bed for that." Natsu turned his head sharply and wanted to protest, but Gray silenced him with a kiss. "Come on, you can go to the toilet for flushing it. It's not like your ass will be dripping all over the place."

Natsu gave in and so they found themselves lying entangled and kissing on the bed not a minute later. Gray was very gentle and considerate. He shifted their positions so that Natsu was lying on him, then created a very small ice cube and slid it slowly down Natsu's back while pressing butterfly kisses along his jaw and on his cheeks. When the ice cube had slipped slightly between Natsu's ass cheeks, he let out a moan and ground his hips against Gray's.

Gray smirked at Natsu's reaction and brushed feather-light kisses against Natsu's open lips while sliding the ice cube further down. It was hard to proceed as Natsu's butt cheeks were pressed firmly against each other, so he spread Natsu's legs wide with his knees. When the ice cube reached Natsu's puckered hole, Gray let it slide around the opening a few times before trying to push it inside gently. The diameter of his roundish ice cube was only half a centimeter at most, but still Natsu cursed when it was pushed inside.

"Shh, relax. Should I make smaller ones?"

Natsu looked him in the eyes and asked, "what makes you think I'm cursing because of pain?" Then he smiled a perverted smile. His tongue darted out and directly into Gray's mouth to have a heated tongue-battle. It lasted only seconds before Natsu pulled back again and rolled his hips suggestively against Gray's. "More. I want so much more."

Gray nearly choked on his breath. Natsu in Dragon Force and with that expression on his face was by far sexier than his poor heart could take. He didn't hesitate to obey and produced some more round ice cubes. He wasn't sure if Natsu would actually notice if he put the half of them inside his own ass, since he couldn't see what he was doing but who knew what his keen ears were able to hear? He'd try anyway, maybe he could surprise Natsu. He'd said that he would let Gray be the one to penetrate him first, but right now Gray was pretty sure Natsu would like either way, seeing how turned on he was. Gray rather hoped it was going to be a long night and they would do it more often than just once, so they could switch and see what they liked better.

Natsu shivered as more and more ice cubes entered his ass and so did he - this feeling couldn't compare to anything he'd ever felt before. The more ice cubes were inside him, the more they moved against each other and the more often they brushed against his prostate. Gray only barely managed to hold back his moans, while Natsu didn't hesitate to express his excitement verbally. Their cocks were sliding together just slightly and Gray thought he was going to come like this if they didn't stop it soon.

"Ah- shit, Gray, it's so cold, but it feels so damn good- hahh- oh shit, G- Gray, I'll c- come, oh god-" and then he let out a long moan, shuddering violently through his orgasm. Gray felt warm cum hit his pecs and couldn't help but lift Natsu's body up a bit, look down and watch Natsu's cock shoot out his seed. The pressure with which the transparent fluid was shot out was high and so some of it landed on Gray's face, across his cheeks and a droplet on his lips.

When Natsu's orgasm wore out and he saw the mess he'd made on Gray's face, his eyes widened in shock. "Sorry, oh no, I'm sorry, wait here, I'll get some toilet paper for you, don't move," he stuttered and scrambled to his feet, but the movement made him hyper-aware of all the water and ice inside his lower bowel and he flinched and walked a bit awkwardly towards the bathroom.

Gray smiled privately and licked the droplet on his lips. Natsu closed the bathroom door and Gray could hear water being released into the toilet and then flushed and some seconds later a flushed Natsu re-emerged with a new toilet paper roll in hand. When Natsu hovered over him to wipe his face, Gray couldn't stop grinning at how considerate and cute Natsu was.

"Gray, stop smiling that pervert smile of yours, I can't wipe your face prop- mhh..." Gray had pulled him down and silenced him with a kiss. It had been meant to be a soft and sweet kiss, but Natsu kissed back with renewed passion and it soon turned into a fight between tongues and teeth until-

"Ouch! Natsu, your teeth are sharp. Can't you quit Dragon Force already?"

"Uh, I can't... Not until I've claimed you..."

"So, we need to have sex and then you'll be normal again?"

Natsu smiled. "Yes."

Gray's cock twitched at the prospect and suddenly he became aware again of the water pressing against his hole from the inside, wanting to be released. "Alright, just let me go to the toilet, to, uh, wash my face... I'll be right back."

Natsu eyed him suspiciously, but moved aside to let Gray stand up. Damn, the water inside him was really uncomfortable and every move made it only worse. He knew his movements had betrayed him already and so he looked over his shoulder to check how Natsu would react. Natsu was grinning at him and mocked, "Eager much, are we?" Gray winked and turned around again, but not without noticing the predatory sparkle in Natsu's eyes.

After closing the bathroom door, Gray sat on the toilet immediately. It nearly hurt to have that much water inside him; maybe he'd overdone it a bit. He tried to release it slowly - but of course that didn't work.

Once finished, he was glad to have done this before letting Natsu touch him there. True to his word, he also washed his face before going back to bed with Natsu, who welcomed him with open arms and a kiss on his forehead.

"Natsu... please, I want you inside me first."

"Anything for you, my snowflake."

Natsu didn't waste any time and turned Gray so that he was lying on his back.

"Spread your legs," he ordered while he reached for the bottle of lube and massage oil on his nightstand.

"So... did you actually buy that bottle with this in mind?"

"Who knows... maybe?"

"When I saw it on your nightstand for the first time, I thought..." he trailed off and blushed.

Natsu had his fingers coated with the lube already and circled one finger around Gray's opening. "When I bought that, I didn't exactly know what 'lube' was used for. I just wanted to give you a massage, that's all. But it does come in handy now," he added and smirked.

Natsu was clearly ready to drop the topic but his statement only stirred more questions that Gray wanted to have answers to. Talking about this wasn't exactly a turn-off (it was quite the opposite - for Gray at least) so surely they could talk and prepare for sex at the same time?

Natsu pushed a single finger inside and Gray moaned. "Wh- when did you find out then? I mean- at some point you did find out what sex was about... When was that?"

The finger inside him moved around a bit before finding his prostate, but when he'd found it, the reaction was overwhelming. Gray's spine arched and he let out a sound that sounded embarrassingly close to a whimper.

"Are you sure you want to talk about that now?"

"Ye- yes! Don't stop what you're doing, just- ahh, yes there- just answer, please."

"Alright. It was on the same evening. After you brushed your teeth... I was- uh... actually, I wasn't sleeping when you came back to bed... I was just... pretending to be asleep, and then you whispered your confession into my ear... and well, then pictures kind of flooded my mind and I knew then."

Gray couldn't decide if he wanted to kick Natsu for this or curl up and die or just be thankful that it happened like this. Natsu disrupted his thoughts by pushing a second slick finger inside Gray's ass.

"Ah, Natsu, god, yes. And then you made me wait two more days before confessing!"

"Yeah, well, I really tried to confess, but, uh, you know..."

Gray would've smiled if there hadn't been a ripple of intense pleasure rolling through his body right that moment.

"Ahh- You're right, we shouldn't- ahh- talk now, oh god, do that again..."

He was rewarded with another brush of fingers against his prostate. He threw his head back and moaned shamelessly.

"More, please. I want you- ah- inside me already," Gray demanded.

"Not yet, I don't want to hurt you."

"Hu- hurry."

So Natsu did. He pushed a third finger inside and spread them wide. He stimulated Gray's prostate with nearly every movement and soon Gray wasn't able to form any coherent thought anymore.

When Natsu pulled his fingers out completely, he nearly complained, but then he felt the slick head of Natsu's cock press against his entrance, and his complaint turned into a moan.

"Are you ready?"

Instead of answering, Gray pulled Natsu's hips in with his heels. They moaned in unison as Natsu slipped inside easily and Gray only stopped pulling when Natsu's cock was buried inside him up to the hilt. It didn't hurt in the slightest. Natsu had really done a damn good job with preparing him.

"I'm inside you."

"I can feel that."

"We're not virgins anymore."

"Yes, yes, I know. Now would you please move?" To emphasize his demand, he rolled his hips and brought his arms around Natsu's torso to pull him down into a hug.

"I'm going to mark you while sex. I hope that's okay for you?"

"God, Natsu, as long as you're not planning on cutting my penis off, I'm sure I don't mind and now would you please start moving?"

Natsu smiled wickedly and pressed a quick kiss on Gray's mouth. "I did warn you. Don't complain later." And with that, he started moving.

Gray hadn't been so sure whether he'd like bottoming. Now he could safely say he loved it and if Natsu decided that he liked topping more, then Gray would gladly comply. Most of Natsu's thrusts hit his prostate and it felt simply wonderful.

No matter how much his body's instincts wanted Gray to close his eyes and simply enjoy this feeling, Gray wouldn't take his eyes off his soul mate. This felt like much more than just two bodies joining for sexual pleasure. This felt like their very souls were fusing with each other's irrevocably and forming a new, complete one. They didn't break eye contact when both were panting and moaning uncontrollably, or when Gray shouted because Natsu had brushed his prostate in that way that made him see stars.

Gray was completely overwhelmed by the pleasure that Natsu brought him only by his penis moving inside his ass. He was sure he'd come soon with his penis untouched and then suddenly Natsu hit his sweet spot again that made his vision blacken out for a second. He managed to blurt out, "Now, ah, now-" and then his muscles contracted and the most powerful orgasm of his life rocked his body. He distantly noticed that sharp teeth were rammed into the crook of his neck, but instead of hurting him, they brought him even more pleasure and prolonged his orgasm.

When the last aftershocks of his orgasm ebbed out, he felt Natsu collapse against him.

"What... the hell... was that?"

"That was sex."

Gray hit the back of Natsu's head playfully. "This wasn't just sex. It was more. It felt like more... Or... is this what sex always feels like?"

"Who knows? It was just our first time." He winked. "But you're right... it was more. I claimed you. The biting marks on your neck are not going to vanish."

"Y- you... marked me... permanently?" Gray blushed furiously.

"Uh, yeah. Oh god, you don't want this, do you? There's still a way to-"

"I love it. I love that people can see that we belong together, I'm proud of it. Though I'd wish I could mark you as well."

"Actually... you have to, because if you don't, then yours will vanish in twenty-four hours."

"How? I don't have such fangs."

"Oh, really?" Natsu smirked. Gray's eyes widened and he brushed the underside of his teeth with his tongue.

This couldn't be true. He had sharp canines now just like Natsu. He would be able to mark him in the same way Natsu had marked him.

Claim him, mark him, make him mine. Hell yes!

He opened his mouth wide and aimed for Natsu's neck.

"Whoa, hey, stop. It has to be done while the one who's bitten has an orgasm." He looked at Gray's exposed teeth and added with a sly smirk, "I mean, you could still bite me now if you're into that. You look so sexy with them."

Unrestrained desire flooded Gray's whole being.

"I'm going to make you scream."
