I edited this cuz I'm writing the second chapter and this needed a lil work
Natsu struggled to walk, his mind was hazy with lust, one he failed to be able to control on this particularly strong full moon. He had already downed a handful of medication, his heat unable to be suppressed. It fought for him to find someone, anyone, to abuse for this one night. He fell to his knees in front of a random vending machine, slipping coins in with shaky fingers as he ordered a cold drink. The juice failed to calm any amount of the fire raging inside of him.
"Dammit," He cursed, knowing that if he didn't try his best to stay conscious, his dragon would take over and let loose on the first stranger to pass him by, may they be male or female. Gray had more than once almost been the victim of his vicious attacks. One nap and one shirtless best friend crafted a story they swore to never speak of again, Gajeel as well after being the one that had to tear Natsu away from the ice devil.
"Ooh, I thought I smelled something nice," A bubbly voice chirped from behind him, his body slow to turn around. He was rightfully wary of the random girl dressed in an unrecognizable school uniform as she waved and walked up to him, her eyes oddly deep purple. Another color would suit her better, he thought.
"Where did y-" She cut him off with her hand, sticking it out for him to shake.
"I'm Lucy," She smiled as he returned her greeting. "I could smell you from over a mile away, y'know. It's not so smart to be out during your heat."
"Shouldn't you be," He shook his head as his vision faded for a moment. "Avoiding me if you can smell that kind of thing? I'm dangerous right now." He strained out, quirking an eyebrow as she laughed.
"I thought you could use some help." She hummed. "Since your pills aren't working, I assume?"
"You have medicine?" He asked, frowning when she shook her head. Natsu gulped as she leaned down, her hand dangerously close to his obvious boner as she touched his inner thigh.
"I can tell you've been pent up for a while, it's making me drool~! I'd hate for you to waste your spunk on the toilet." He was taken aback for a moment, expression obvious as she laughed as he flushed and his lips sputtered.
"The hell are you?" He asked, cringing as she basically sat in his lap, senses twitching wildly for him to devour her.
"A succubus," She said, unbuttoning the bottom of her shirt to reveal the heart-like tattoo that sat under her belly button, though it more closely replicated a womb. "The other half of me usually isn't so good at letting us eat when we're hungry. She's pretty upset that I came out to find you, but you smell so good, I couldn't stay away."
He gulped, vaguely relating to the girl that also had a hard time keeping their more wild side under wraps. He probably wouldn't hate to meet the actual person she was, the one in front of him right now was rather annoying and cocky.
"So, what? You want to have sex?" Natsu flushed further as she nodded, groaning as she dropped her weight onto the stiff tent of his pants.
"You clearly need it, and I'm starving. We can have some real fun if you don't mind coming back to my place." She intrigued him, a quick kiss enough to make him lose all sense of self. The extent of her abilities moved their bodies rapidly from the park and to her home, Lucy pushing him through her door. Natsu was unable to fully comprehend just how quickly they ended up stumbling into her home, the blonde swinging her hips and leading the distressed dragon toward her bedroom. He sat on her bed and flushed as she stripped from her clothes, a growl low in his throat at the sensual sight.
"S-Should we really...?" He asked apprehensively, eyes wavering and anxiety low in his belly as her clothes fell and she stood in pale blue lingerie. "I don't know if I'll be able to stop myself,"
"You don't need to," She scoffed with a delighted grin, straddling his lap and pushing him back onto her mattress. "You never told me your name, by the way."
"Natsu," He breathed as she teasingly ran her hands under his shirt.
"Don't worry about hurting me," Lucy giggled as she felt his hesitation, dipping down to whisper into his ear. "My body is made to handle rough sex. You can do whatever you want to me."
He indulged in the beast screaming to take over, his body quaking as he rightfully gave the reigns to his dragon. Lucy bit her lip excitedly as she watched his scales freckle and climb up his body, teeth gnashing as his fangs grew in, horns curling from under his pink locks. She moaned as his heat spread through her, body tingling with intense hunger as his new form gazed deliciously at her.
"I hope you know what you're getting yourself into," His gruff voice smirked, hands gliding up her thighs and pulling lightly on the front of her panties, enjoying the slight rock of her hips against his.
"You're the one," She lamented, lowering herself once again to slide her tongue slowly against the scar on his neck. "Who doesn't know what he's getting into."
Their grins were both wild as they kissed, holding each other with a needy tight grip, hips grinding together roughly. Tongues clashed together in the midst of their heat, Natsu moaning at the taste of her dripping mouth. Her fingers raked in his hair, feeling up his horns and enjoying the sharp scrape of his canines against her plump lips.
"Let's skip the foreplay for now," She panted as she rose to straddle him, her sensitive button grinding against the tip of his dick. "I don't want to wait any longer."
Natsu woke with a gasp, throwing himself forward in a cold sweat and sitting up to look around quickly. The sun was low in the sky outside, the room vaguely recognizable. His phone was ringing wildly from his pants pocket on the floor beside him, grunting as he dropped a sore arm to grab it.
"Natsu! Where the hell have you been?! I've been calling you for at least two days!" Erza shouted, making him cringe and shake his head of any further tiredness. He failed to answer as he sat with a slack jaw; how had two days passed without his knowledge? His phone fell to his lap as Erza continued to yell, asking for his location and spouting threats for more information on his disappearance. He abruptly hung up on her, though he would probably regret that decision as he scrolled through his notifications.
There were texts from each of his friends asking why he wasn't at school the past two days, others telling him they'd be coming over to his house to give him his homework. Even Gray and Gajeel had texted and spammed him with calls, threatening to beat him up for worrying the girls. He frowned at the messages from Lisanna, beyond concerned for his well being. She was his best and oldest friend, his heart clenching a bit at the sight of twenty calls from her and texts asking if he was okay. Though she said she trusted him no matter what, if he were in a tight spot she would do anything to help him. He was especially surprised to see that his senpai; Laxus and Jellal, had even texted him; they usually didn't, now feeling the extreme guilt for handing over his body to his dragon. Natsu at least had the courage to update his social to let everyone know that he was okay and would be home later that night.
Though he could tell that it and himself were thoroughly satisfied, his mind having never been clearer and the stress gone from his body.
He blushed as the memories began to flood his mind, vivid images of Lucy underneath him, her skin riddled with his eager bite marks. They trailed down her neck and littered her supple chest, eyes exciting as he slipped in between her thighs. Her flavor was faint on his tongue, the heat of his cheeks increasing as he remembered how unbelievable she tasted. Natsu was suddenly aware of how naked he was, his lower half slowly responding to his thoughts. His nose revealed the trail of their overzealous lovemaking. He hurried into the bathroom as his length was quick to rise, hoping the cool water would calm him down. His thighs and torso were still sticky with their fluids, his head falling into his hand as he groaned.
Looking into the mirror, he flushed at the sight of so many purple and red marks that had littered his neck, mad their way down his chest and stomach, varying around his thighs. Lucy's purple eyes staring up at him as she marked his body was sharp in his mind, hand rushing to turn on the shower and submerge himself under the cold stream.
His mind betrayed him as he remembered the heat of her mouth on his sex, hungrily assaulting him for his seed. She giggled as she ran her tongue from the base of his cock to the tip, enjoying the snarl he produced at her actions.
"You're so thick, Natsu," She hummed as he bit his lip.
He growled and sat up, fisting her hair roughly as he forced his length past her lips. He grinned at the sight of her watery eyes, filling her mouth with what she craved.
Natsu grimaced, panting as he let go of himself and washed away the spunk splattered in his palm. He left the shower after washing with impressive speed and shampooed the sweat from his hair. He dried himself in a whisp of fire, awkwardly walking back into the room stark naked to redress himself in his strewn about clothing. His nose caught a whiff of the cooking going on behind the closed bedroom door, cautiously walking out and towards the small kitchen to investigate. He was surprised to find the girl humming and bobbing her head to the music playing through her earbuds, a noticeable amount of food already plated on the table. He flinched as she shrieked, the wooden spoon falling to the ground as it slipped out of her fingers.
"O-Oh, you're awake! I'm sorry, I was kind of preoccupied," She said sheepishly as she removed her earbuds, setting them and her phone to the side as she bent down to pick up the utensil.
"No, that's okay. I'm sorry I scared ya," He chuckled, an awkward silence building between them before she turned back to finish plating the stir-fry she made. He was slightly in awe, her looks had somehow improved since the last time he lucidly remembered her. Her skin was brighter, eyes suddenly brown, hair seemingly more silky.
"Your eyes... they're not purple anymore," He pointed out, leaning against the counter across from her stove.
"Oh," She laughed a bit as she set the last plate on the table. "That was my...other side, I'm more myself now than I was before. Sorry about getting you mixed up in this."
"I should be apologizing to you," He shook his head with a quiet chuckle. "I can't believe we went at it for two days, I wasn't myself at all."
She flushed with a crooked smile and nodded, turning away in embarrassment at the mention of their activities.
"I hope you're hungry," She said quickly to change the subject, motioning for him to approach the table. "I never get to cook for myself, so I went a little overboard."
"Starving, actually. Thanks a bunch." He drooled a bit as he took a seat, digging into practically a feast she had crafted for him. Natsu lost himself in the meal for a little while after moaning over her amazing skills, though looked up to notice that she wasn't eating anything but a small bowl of fruit.
"You're not going to eat? I'd feel bad finishing this on my own,"
"I can't eat anything besides fruit." She explained, "Well, you know, besides... but it doesn't do much other than take away hunger pangs."
What she had said the night they met flashed into his mind for a moment, a frown spreading across his lips. "How long has it been since you've eaten from anyone?"
"I-I'm not sure," She laughed awkwardly, folding her legs in a crisscross on her chair. "It's been so long, I really lost control of myself the other day when I caught your scent."
"Eh?! That's terrible, no one should have to live like that." He frowned, her expression surprised at his intense concern.
"I'm pretty used to it by now," She shrugged him off, trying her best to fight off the impressed blush that rose to her cheeks. "I don't want to live my life sleeping with random guys, as much as I need to."
Lucy sighed as she popped a grape into her mouth. "But I haven't felt this great in years if I'm being honest, I had no idea how weak my body was this whole time. I hope I didn't steal too much of your energy."
"I was in crazy heat," He shook his head to reassure her. "I'm surprised you're okay. I know when my instincts take over that I don't hold back."
"That explains why you seem like such a different person," She laughed, the sound bubbly and rang like a chorus of bells in his ears. "I wasn't expecting you to be so nice,"
"Oi," Natsu pouted as she continued to laugh, his lips betraying as they pulled up in a sweet smile.
"I hope your family isn't worried about you, going missing in the middle of the week couldn't have been good."
"Don't worry about them, they're overseas right now. My friends'll probably gimme hell for not picking up my phone, though."
They continued to speak lightly through their meal, Lucy much more engaging than Natsu assumed, and she felt the same. He thought she was incredibly adorable and surprisingly had a sharp tongue at times. She remembered him to be overly dominant (not that she minded) and strict, his demeanor hard and animalistic during their hazy night. He was goofy and aloof, her heart clenching wildly whenever he grinned so widely. Their meal had come to a surprisingly quick end, the sun gone, and the two somewhat unreluctant to part.
"So, um, thank you again," She smiled and tucked a strand of hair behind her ear as he stood in her doorway. "I had a lot of fun."
"Me too," He mumbled, scratching the back of his neck as he thought of more to say. "I don't remember much, but you were...a-amazing." They stood quietly as they blushed, kicking their feet and laughing clumsily as they made eye contact on and off.
"When you get hungry again, I wouldn't mind if you wanted to see me," Natsu gulped as her timid brown eyes met his nervous onyx ones, her arms folding behind her back nervously.
"...You really mean that?" Lucy asked, her cheeks redder as he nodded.
"I don't want you going hungry, 'specially if I know I can help you out." He shrugged, looking away as she smiled. "And I want to see you again too."
"Then let me give you my number," Their hands were both mildly shaking as they shared their infrared codes, both letting out a shy breath as they received each other's contact. Natsu felt a rise of courage in his chest as he dipped down for a moment, hand against her cheek as he molded his lips against hers in a soft embrace.
"Just a snack to ho-" He started as he pulled away, Lucy quick to wrap her arms around his neck to deepen their kiss. He purred as her tongue slipped into his mouth, both swirling around each other, his hand traveling to the small of her back to pull her closer. He hit her front door, the two of them sliding to the floor as their want bubbled madly up their throats. Natsu panted as she pulled away, one eye brown and the other its familiar purple as she rolled against his forming hard on.
"W-Would you please stay the night?"
"...Y-Yeah, whatever you want."
