A blazing hot sun beat down on the beach from overhead as Mirajane Strauss moaned quietly around Natsu Dragneel’s cock! Her plump and soft lips dragged back and forth on his dick as he let out a groan every time she took his length down into the pit of her stomach. The pink haired young man groaned at the feel as the platinum haired beauty held his cock in her mouth and stomach for several long moments. Her sapphire blue eyes rolled back in their sockets.

 

“GUMMMMMMMMPH, SHO PHIIIIICK…!” she moaned, a sound more akin to someone eating something delicious than anything else. She then began moving her head back and forth again, her lips making all kinds of lewd, wet, slurping sounds as she gagged quietly.

 

“Ahhhh, Mira…!” Natsu said, “You’re sucking so intensely!”

 

“AYE’M HORNYYYYYY!!! AN’ UR GIRLSH AHREN’T HERE EIDERRRR…” Mira slurred, rocking herself on all fours, using her entire body to suck his massive dick.

 

She was right, Lucy, Flare, and Brandish weren’t here with them at the Akane Beach Resort. All three were back in Magnolia, preparing for a job that just came through. The reason he was here with Mira is she wanted him for “Body Guard” duty while she did a fashion shoot with Jenny Realight from Blue Pegasus. The two women were doing a photo spread for the next Sorcerer’s Weekly Summer Fashion Week.

 

And while Mirajane could easily look after herself, what she wanted was someone to handle her enhanced carnal desires now that her inhibitions were pretty much gone! Natsu looked down at her pretty face and the way her lips pulled away from it every time she pulled her head back. Such an erotic sight, his dick felt even harder just looking at her like that.

 

“VESHIDESH, DHEY SHAID ID WASH OHKAAAY!!! AGUMPH, GUG, GWEH, OH PHUG UR CAWK TASHTESH SHO GUUUUUUUD!!! AYE WUV DISH PHEELINGH GUH GUH…!” Mirajane said, moving her body even faster as she shoved both hands between her legs. There was a tearing sound as she ripped off her bikini bottoms before she began masturbating furiously. Natsu could smell her pussy gushing with hot juices as she made herself cum again and again while bobbing her head on his dick!

 

He had already grown to love that smell, the scent of a woman in lustful heat! It made his head feel dizzy with his strong Dragon Slayer nose. He remembered some of the older Guild Members talking about how sex could stink in the literal sense and not the figurative. But Natsu didn’t think so! Every girl had their own unique smell. Lucy’s was kind of airy like the smell of a snow covered field. Flare had a SPICY smell to her, while Brandish reminded Natsu of the smell of a desert. And all still had a musky smell that he’d heard about as well, and Natsu guessed that was what the guys were talking about.

 

Mirajane’s pussy, oddly, had a smell like lots and lots of flowers in it. Natsu wondered if that had to do with her living in Magnolia for so long. But as the platinum blonde woman pulled her mouth off his cock with a sucking ‘pop’, he decided he didn’t really care. Mirajane looked up at him, panting hotly as she began licking and sucking on his balls while she stripped out of the sexy micro-bikini she had been wearing. Her huge tits jiggled free, pink nipples already stiff as she grabbed at the fleshy mounds.

 

“Nmmmmmah, thanks for coming out here with me, Natsu.” Mirajane said in a conversational tone while licking up and down his cock and balls. “I had this shoot planned with Jenny some months back, before everything went crazy.” she explained while peppering his dick with kisses. She held the thick length with both her dainty hands, smiling as she couldn’t bring her finger tips together even using them both.

 

She licked her lips as she eyed his length before sitting up on her knees and pressing her big, soft, heavy tits around the shaft. The feel of them made Natsu groan again as Mirajane began stroking his cock slowly, again moving her whole body to accomplish the task.

 

“So,” she again asked conversationally, “Have you all set a date yet?”

 

“Date?” Natsu echoed.

 

“For your wedding, duh!” Mirajane said, leaning down to lick the top ten inches of his dick, “You all got engaged a couple weeks ago I know, but you haven’t set a date yet?”

 

Natsu rubbed the back of his head, grinning sheepishly, “Oh right, that. Hehehe. I thought you meant like a dating date.”

 

“You’re lucky you’re this hung, Natsu.” Mirajane said with an overly dramatized roll of her eyes, she then took the top few inches of his cock in her mouth. He groaned a low groan as he felt her tongue swirling around the tip of his dick as she continued to speak. “Ewe guy’sh khindah shkipped dat pahrt, bud dat’sh ohkay. Nafta eberiphing ewe’ve been trew twogedda, ewe dhon’d nheed dat pard…”

 

Natsu only caught about half of that, not because it was so garbled, but because of how GOOD her mouth and tongue felt on his cock. Part of him thought he should feel bad, doing this kind of thing with Mirajane when he had not one, but three fiances back home. But then again, they knew why he was out here with her. Mirajane’s words from after the orgy the other day still rang in his head.

 

He had just finished fucking Flare in her asshole while Lucy and Brandish did that sixty-nine position thing on the table when Mirajane came up to them. “Hey Lucy, Brandish, Flare!” she had said, “Can I borrow Natsu for a couple of days?” she asked, when Flare and Lucy asked why, Mirajane answered honestly, “I’m going for a fashion shoot at Akane Beach with Jenny, and I need a guy I can have sex with while I’m there. I wanted to ask Laxus, but he already left. And I really don’t wanna end up with some strangers when I get horny.” she explained as if she were telling them what groceries she needed.

 

The girls looked at each other, with Brandish being the first, “I don’t care either way,” she said in a disinterested tone. Flare didn’t like the idea of being away from her master for any length of time, but then Lucy spoke up.

 

“Teach me that futanari spell thing you used, and you got a deal.” Lucy told her.

 

Now, Natsu was here.

 

He looked down at Mirajane and licked his lips as he watched her gobble his cock while massaging it with her huge tits. Her blue eyes seemed to smile up at him as she began taking his dick deeper into her mouth again, the ponytail she made with her bangs wobbled back and forth with her motions as she let out a long, deep moan, making her throat buzz pleasantly around his cock.

 

On a whim, Natsu reached his hand down and grabbed that ponytail, gripping it tight before he began moving his own body. He swung his hips back and forth, plunging his dragon dick in and out of Mirajane’s face, fucking her mouth as if it were her pussy! Flare loved when he did stuff like this, Lucy too when the mood was right.

 

“HUGUUUUUUUHHHPH!!!” Mirajane gagged loudly, her eyes rolling back in her head as her entire body bucked around his dick. For a split second, Natsu worried he’d made another stupid mistake! But, only for a split second, as Mirajane’s gag of shock switched over to pleasure as she quickly adjusted her body position.

 

“NHAAH!! HAHG, HNG, MMMHN… MMHN NHNN!!!” Mirajane gagged loudly, ropes of her drool flinging away from her lips every time Natsu pulled back. “NNGH MMMNM! GUH GUG AGUH GUHPHMMMH…!”

 

“Ahhhh, yeeeah, you like that, Mira!?” Natsu groaned, “Like taking my fat dragon dick in your throat!?”

 

“HMMMMMMPH, GYEEEESH, MOAR!!! MMMMMMMH, MMMMMPH!!! PHUG MUH MOUPH WIKE A PUSSHYYYY!!! OGHPB, NGHMMM, NGHOH, NGHMMMMN, UPOWOO, HOGOOOH NBOHJUBOBOH OGOOOH!!!!” Mirajane choked out, her pussy gushing so hard, he could see a line of her juices shooting out behind her.

 

“Awww yeah, yeah, yeaaah…!” Natsu groaned and grunted, slamming his dick into Mirajane’s mouth even faster. Her deep blue eyes rolled back again as her entire body shuddered with pleasure.

 

“GUUMMINGH, AYE’M GUUMMMINGH FROHM MUH MOOOUUUPH, GUH GUH GUH GWEEEEGH!!!” Mirajane wailed in pleasure. “AGUH, GUH, GUG, GWEEEGH, GUUUUG, SHO GUUUUUUD… AGUH, AGUH, GUH, GUH GUH GUH GUH!!! GUUUUMMMMINGH!!” the platinum haired woman choked out as she continued climaxing.

 

Natsu felt a pressure mounting in his balls as he listened to Mirajane’s choking gags. Knowing this feeling well now, he began fucking the girl’s face even harder, letting that sensation build on itself until…

 

“GWOOOOOOOGH!!!!!!!!!!!” Mirajane gagged loudly as Natsu began cumming right into her stomach! He shoved his entire massive length into her mouth, emptying his load into her belly as she let out a muffled moan. He could see her pussy gushing again as she came from the rough treatment and smiled.

 

The pink haired young man waited until he finished cumming before pulling his cock back out. Mirajane took in several deep gasping breaths, coughing only lightly from the ordeal before she stood up on her knees with her usual sweet and innocent smile.

 

“That was fun!” she said cheerfully before she moved to turn her back towards Natsu and kneel down on all fours, presenting her ass to him. She then reached a hand down between her legs to pry apart the dripping pink folds of her pussy. “Now do that again here!” she told him, then giggled.

 

Natsu grinned back at her, cracking his knuckles before reaching out with both hands, “Alright,” he said, grabbing her ass in both hands. The plump and sexy cheeks were soft to the touch, but he could feel the layer of muscle beneath. While she didn’t look it outwardly, Mirajane was actually quite strong both physically and magically. Her demonic possession magic allowed her a variety of frightening demonic forms, with all of them being quite strong. Which made her slender, but buxom pin-up model look all the more deceptive. Anyone who didn’t know who she was always underestimated her because of that.

 

He placed the tip of his cock against the pink folds of her moist pussy and felt her pulling her fingers out of the way. She turned to look back at him with a grin, “Nmmmmmh, I’m gonna feel this in the morning, just like last time!”

 

“That a complaint?” he asked, his cock twitching against her hole.

 

Mirajane looked genuinely insulted, “Not even! Jam that sucker in there!!!” she demanded.

 

“You got it!” Natsu said back, grinning again as he rammed his cock inside her with a wet SHLICK sound.

 

“HEEEEEEEEEGH!!!” Mirajane hissed through clenched teeth. “BIG, SO BIIIIG! IT FEELS LIKE YOU’RE GONNA SPLIT ME IN HALF NATSUUUUUU!!!” Mirajane screamed in pleasure!

 

“Aww fuuuuck, your pussy is so tight Mira, I can barely even fit inside!” Natsu groaned, pushing his length deep inside her, his pelvis smacking against her plump butt.

 

“AHHHHN, MY PUSSY IS BEING SPREAD OPEN SO WIIIIIIDE!!! IT HURTS, BUT IT FEELS SO GOOOOOOOD!!! MORE!!! SHOVE THAT GIANT DRAGON DICK INTO ME MORE!!!” Mirajane screamed at him as she began rocking her body back against his thrusts. There was a soft PLAP PLAP PLAP sound as Natsu pounded his cock in and out of her. He watched the way her pink pussy seemed to cling tightly to his cock as it moved in and out of her.

 

“HAAAAAAHN!!! I’M SO FULL! FULL OF COCK!! I FEEL SO GOOD, CUMMING, I’M GOING TO CUM ALREADY!!! OHHHHHH YES! YOUR GIANT DRAGON DICK IS MAKING ME CUUUUM!!!” Mirajane screamed.

 

Natsu groaned, closing his eyes and leaning back as he swung his hips wildly, loving the feel of her pussy clenching around his cock. “Hurr, hurr, hurr, hurrmmmh!!” he grunted every time he slammed his dick back inside her.

 

“AHHH YES, DON’T STOOOOOP!!! MORE, GIMME MORE! MORE DRAGON DIIIIIICK!!!” Mirajane demanded, turning to look back at him with a look of wild lust on her face. “YOUR GIANT DICK IS COMPLETELY STUFFING MY INSIIIIDES!!! THERE NOTHING BUT DICK NOW! AHHHN, DRAGON DICK IS THE BEEEEST! I’M GONNA GET ADICKTED TO THIIIIS!”

 

Natsu laughed at the pun she made, then slapped her ass as the air around them began heating up. “AHHHHN, NOW YOUR COCK IS GETTING HOOOOOT!!! IT’S LIKE I’M BEING JABBED WITH A HOT POKERRRR!! BUT IT FEELS GOOD, YOUR DRAGON DICK IS TRYING TO BRAND THE INSIDE OF MY PUSSYYYYY! TO MARK IT AS YOURS! I DON’T MIND BUT LUCY WILL BE JEALOUUUSSSSSS!!! OH FUUUUCK, SO HOT, MY BODY IS BEING COOKED!! AHH, AHHH, AHHHH, CUUUUMMMMMINGH!!!” Mirajane screamed, her pussy gushing hot juices all around his cock. Those juices turned to steam against his hot skin, and Natsu groaned as he reigned in his powers.

 

“Huh, why are you stopping!?” Mirajane asked in a confused voice, turning to look at him again.

 

“I uh, don’t wanna hurt you…” Natsu said, the air around his body still rippling from the heat he was putting out. Flare could handle this with no problem. In fact, the two of them seemed to feed off one another’s fire when they fucked, making several smoking craters around the landscape.

 

Mirajane smirked, “Seems you forgot whose pussy you’re stuffing!” she said as a wave of pressure emanated from her! Her ears then elongated and her face became sharper as her hair began standing on end and a long tail emerged from above her sexy ass. Mirajane’s Satan Soul form grinned back at him and spoke in her deepened voice.

 

“I can handle a little heat! Now, FUCK MY PUSSY HARDER!!!!” she yelled.

 

“HURRAAAAAAAAGH, FIRE DRAGON DRILLING DIIIIICK!!!” Natsu bellowed, while the heat around them intensified as he began pounding into her again, grabbing hold of the Satan Soul form’s long tail. His whole body was enveloped in flames as he drove his cock in and out of her without mercy. All around the two of them, the sand began melting into glass wherever it was in direct contact with Natsu’s body.

 

“AHHHHHHEEEEEEEE!!! SO HOT AND GOOOOOOOD!!! I’M CUMMMMMINGH!!! MY INSIDES ARE BEING BRANDED BY NATSU’S DRAGON DICK AND IT’S MAKING ME CUUUUMMMMM!!!!” Mirajane screamed, her voice that same cutesy high pitched one she normally used.

 

“Yeeeah, yeah, yeAH, YEAH YEAH YEAH YEAH HAAAAAAAAAH, FIRE DRAGON ROOOOAAAARRRRRR!!!!!!” Natsu howled, throwing his head back and shooting a massive pillar of flames straight into the sky as he began cumming inside Mirajane. While the patch of beach they were on wasn’t occupied, people for miles around the resort area could see it clearly.

 

“HOOOOOOOOOOH, SO MUCH CUUUUUUM!!!! YOU’RE FILLING ME UP NATSUUUUU…!” bellowed Mirajane in her Satan Soul voice. He felt her pussy gushing around his cock as his balls emptied themselves into her womb.

 

The fire pillar his roar produced was as short-lived as it was intense, vanishing as soon as Natsu stopped yelling. He then fell backwards, his cock pulling out of Mira’s demonic pussy with a SHLOOOP! The platinum haired woman fell forward on her face, panting hard as her body returned to normal. Her pussy remained gaping wide, letting anyone who looked see deep into her depths.

 

“Aheheh, that was greaaaat…” Mirajane giggled, “And you do that with Lucy and the other two all the time? I’m jealous!”

 

Natsu needed a moment to catch his breath before he replied, “Lucy and Flare, yeah. Brandish, now that I think about it, not so much. I don’t think she’d say no, it just never really turned out that way.”

 

Mirajane got up on her knees again and tutted him, “Tsk tsk tsk, that won’t do. Brandish will be your wife too. And while society may frown on me admitting this, we women have needs too! You should devote your energy to satisfying her as well!” she chided him.

 

“Actually, that’s not an issue with this.” Natsu said, holding up his left hand to show off the ring he wore there.

 

Mirajane covered her mouth, “Oh riiiight! I totally forgot about that. Wait, did you have that turned on just now?” she asked.

 

“Huh, well I…” Natsu began before he flew to his right as if struck by an overwhelming force, “GOOOOOOMPH!” he grunted as he landed face first in the sand.

 

There was then a soft ringing from the bag Mirajane had brought with them. Natsu rubbed his reddening cheek as the platinum haired woman retrieved a lacrima phone from within and answered.

 

“Hello hello, Mira here!” she said in a singsong voice. “Uh huh, yeah, yes we did. Oh really!? I’m sorry! I didn’t know he had it on!” Mira said to whomever was on the other end of the phone. But from the rapid beat of his heart, and a hot sensation in his chest, he had a solid idea who she was talking to.

 

“Yeah, he’s right here.” said Mirajane as she came over to him and held out the phone, “It’s for you.”

 

Sighing in defeat, Natsu took the phone and put it to his ear, “Hello…?”

 

“DUMBASS, DUMBASS, DUMBASS, DUMBASS, DUMBASS, DUMBASS, DUMBASS, DUMBASS, DUMBASS, DUMBASS, DUMBASS, DUMBASS, DUMBASS, DUMBASS, DUMBASS, DUMBASS, DUMBASS, DUMBASS, DUMBASS, WE’RE TRYING TO WORK HEEEERE!!!!” Lucy’s voice shrieked through the speaker, though he barely heard it as his head began moving from side to side as if being smacked repeatedly. He could also hear a loud SLAP SLAP SLAP SLAP through the phone as Lucy yelled.

 

After several moments, Lucy stopped, and he heard her whine, “Owwww, is this how it feels? Ohkay, Aye godda whold bhack a wittle.” he heard Lucy say over the phone, with her voice sounding as if her lips were swollen.

 

“Ahehehehe, pweashe brincessh, shlap meh moar!!!” Natsu heard Flare’s voice, sounding almost drunk with ecstasy.

 

“No, please feel free to take out your frustrations on me, Princess! I welcome your punishment!” came Virgo’s flat and near emotionless voice as well.

 

“Ugh, are you done yet? We need to finish this job.” said Brandish’s voice, sounding more annoyed than in pain, “And that really stings, you know.”

 

“Showwy!!!” Lucy’s voice said before the phone call disconnected. Then, just as suddenly as the pain began, it stopped as someone in their body-link quartet severed the link.

 

“Oh man, I’m in for an earful when I get home…” Natsu muttered, looking at his engagement ring. A gold band with his birthstone set into it. He’d gotten so used to having the link on all the time, that he forgot to turn it off before fooling around with Mirajane. Lucy, Flare, and Brandish had all just felt his sensations as he fucked the bubbly platinum blonde here on the beach.

 

If they were in the middle of a job, that could certainly be distracting. Which was something he realized well too late.

 

“Oh, so it was you.” said a new voice, and Natsu turned to see a familiar face approaching them from the east. Jenny Realight approached the pair with a smile on her pretty face. “Quite the lightshow just now. Mind if I join you?” she asked with a cheeky grin.
