Quick warning, this chapters as a lottttt of steamy stuff. Just a headsup, so, enjoy!💗😧👏

...


"Be gentle..."

"Okay, okay... I'll be gentle since this is my first time."

Crystal screamed, throwing her head back, gritting her teeth and squinted one eye shut. She looked down at the pinkette who was unwrapping her bandages on her knees to take a bath for the morning.

"I haven't touched you yet..." Natsu sweatdropped.

"Okay, okay! Just, hurry up!" She closed her eyes, looking away.

His hands inched closer to her bandage wrapped knees that had a red tint to them. Natsu started from the bottom of her ankle and made his way up, he looked at her knees with confusion.

Where the hell was the wound?

The bluenette opened her eyes when she realized he stopped his actions, Crystal looked down at her knees and saw no marks there. The pain was still lingering but the wounds were gone.

As if they just disappeared somehow...

"Um... Did you do something?" Natsu asked, raising a pink eyebrow.

"No, I did some magic and it went away." Crystal deadpanned. Natsu rolled his eyes.

"Meanie."

"But honestly, I don't know. I always noticed I healed faster but this, this is a weird phenomenon."

"Can you use smaller words?"

She giggled. "I'm sorry, it's a weird thing to happen."

"That's much better." He smiled. The pinkette got off his knees, dusting himself off.

"You know what that means..." He pumped his fist up in the air. "INTIMATE TRAINING!"

The blood rushed to the sky blue haired woman's cheeks. "B-baka!"

"We're taking a bath together!"

"No, we are not!"

"Yes we are!" Natsu picked her up bridal style, grinning like he won the lottery. Crystal's face was so red that it could rival Erza's hair. The pinkette rushed downstairs with the bluenette in his arms, crying animated tears.

...

Hot white tuffs of steam and the scent of strawberries filled the tiled room as Crystal eased her way into the clear hot water that filled the pearly white tub inside of the downstairs bathroom.

She cringed slightly as the hot liquid stung her sore limbs, soon relieving the aches and stiffness from the actions from Midorima, the heat and oil worked their way into her weary limbs.

"Scoot over so I can come in too." Natsu scratched the back of his head as he waited for the bluenette to comply.

Her face reddened once again when she noticed that he had discarded his boxers after he had placed her into the relaxing bath. The bluenette's eyes travelled greedily over his delicious body, going wide when they spotted the very large hard erection that he seemed unfazed by.

"Oi, Chrytal?" He waved his hand in front of the sky blue haired assassin who appeared to have been turned to stone, hopeful that the 'Chrytal' remark would snapped her out of her daze.

"Hmm…Oh yeah….Sure…." She mumbled absentmindedly as she moved forward in the neutral coloured tub.

Natsu got in behind her and immediately pulled Crystal into and embrace, locking his arms possessively around her stomach. Her face flushed.

"Do your limbs hurt?" He asked, his hands grazing over her shoulders.

"Y-yeah... It seems the pain didn't go away, for some odd reason..."

"I thought you'd want a hot bath. Your muscles felt a bit stiff, I was sure they'd be bitching when you woke up."

"So you felt me up while I was asleep? Pervert..." She faked a tone of offense, a tone that he with not easily buy due to the huge smile that she wore.

"Only a little….You wouldn't wake up." Natsu nuzzled into her sky blue locks.

His hands made their way to her back and skimmed along the delicate arch of the spine as he sort the root of her pain.

"Tell me where." His voice took on the tone of authority.

"There." Crystal indicated softly.

"Here?" He whispered hotly against her ear before his thumbs kneaded into the knotted muscles of her lower back. The bluenette groaned when she felt him massage along her spine, fingers locked around her slender waist and thumbs digging into her tense muscles.

A whimper left Crystal's pink, plump lips when she tried to mouth out a response to his question, his skilful fingers working magic on her voluptuous body.

Natsu squeezed on the flesh of her shapely hips as his thumbs rubbed small yet firm circles along the centre of her back making the beautiful bluenette writhe and moan against him.

"Where else?" The huskiness of his voice made her shiver.

"Here." Crystal grabbed hold of his hands, all too eager to lead the way.

His hands roamed over her shapely hips, brushing slowly over her stomach before the where place on her soft inner thighs and left to their own devices when she removed her hands. Natsu pressed firming into the strained muscles of Crystal's inner thighs beneath the water, purposely ghosting over her sex with every caressed.

She moaned quietly as his strong fingers worked into her thighs, leaning her head against his shoulder, staring at the scar that adorned the fiery assassin's neck.

He moved hastily up the curvaceous sides of her body and cupped her full breasts within his rough hands.

Natsu squeezed on them gently making her head roll along his broad, lightly tanned shoulders.

"Do they hurt too?" He asked, grinning slyly against her wet skin.

"A-ahhh..." Crystal hissed as he groped her plumb mounds gently.

"How should I make them better?" He purred into her ear.

This was training... Of course it was! Which is why it was good! But, her moans... Her groans... It just, didn't feel right. It felt forced to him, ever since he's been having those sort of dreams, it always ended up bad.

He either took her without consent, her rejecting his feelings or she just felt disgusted by his actions. But he didn't care about that now, she was the only one...

The only one who can satisfy his needs. His urges. Really... Dirty urges... She was the forbidden apple that hung from the tree, she was such a sweet and blissful sin to want...

Natsu smirked against her ear.

"Naaatsuu..." Crystal mewled and arched into his talented touch, gritting her teeth to prevent from making anymore noises.

"Is this what you want?" He squeezed them harder, making her yelp.

"Tell me how it feels, it's training... You have to tell me how it feels so I can improve..." Arousal cracked in his voice.

"I-it feels... Ahhh... Feels... G-good..."

"Not good enough, it seems... I want to hear you moan louder..." Natsu tugged and twisted her perky, pink nipple in order to invoke a response. He grinned mischievously.

"How about down here? We are going on step further after all..."

He trapped her body against his, removing one of his hands to snake down into her thighs and between her folds. Natsu plunged two of his longest fingers inside of her moist hole, Crystal gasping from the suddenness. She groaned loudly from both pain of the rawness of her sex and pleasure.

"I'll make you feel better... Uhhnnn... From inside and out..." The pinkette groaned as her core accepted the width of his knuckles. His thumb finger made its way to her clit, the pad of it rubbing gently over it.

"How does this feel?..." He whispered in her ear, nibbling on her ear. Crystal responded by moaning loudly when he snapped his wrist sharply, grazing a certain spot.

"How does it feel to be fingered by me?... My fingers all swallowed up by your tight... Uhhnn.." Natsu groaned.

"Wet..."

"Pussy...?"

"Ahhh... Aahhhhhh! Natsuuuu... Please..."

"What do you want?" He pressed his thumb harder down unto the fleshy ball of pleasure, the bluenette's head rolling along his shoulders.

"Tell me what you want... Do you want it..?" Natsy rocked his hips against her, his erection sliding into her plump rear.

"Do you want my cock inside you? Deep inside you?..."

The pinkette found a rough, textured spot on her upper walls when he curled upwards, Crystal moaned loudly, her hands gripping the rims of the tub tightly. Natsu liked that sound... He liked how loudly she moaned.

"Do that again..." She breathed heavily. "H-hit that spot again, right there... Oh God... Right fucking there..."

"There?" He smirked, his fingers all too eager to please her. He continued to hit that certain spot that made Crystal moan and scream out loud, panting and breathing heavily as a big, bright red blush coated her pale cheeks.

"Yes... Yesss!" Her breasts jiggled with every deep and hard thrust he took. "Ahhhh! God! Natsu! Harder! Faster!"

"Chrissy... I want you to scream when I send you past the point of insanity."

"Moan my name out loud for everybody to hear..."

"Cry and come... Over and over again till you have no more to give... Come for me, Chrissy..."

His dirty words rang through her ears like a never ending song. Crystal let out a loud scream as she stiffened when a powerful orgasm made her see blinding white stars. The water becoming white. The sky blue haired woman fell unto Natsu's back, panting hard. Natsu pulled out his fingers from her drenched wetness, her come all over his fingers.

His cocky smirk slowly dropped into a frown.

This was okay, right? His instincts took over for a brief moment, nothing was wrong with that... Or so, Natsu thought.

"That was great..."

Natsu looked down at her.

"That.. Was my first time doing that... It was amazing, not gonna lie... The girl who you like is gonna be very lucky..." The bluenette softly spoke. "Although, depending on the type of girl, dirty talk is an option... R-remember that.."

"Crystal... Are we gonna do this again? Because next time, I won't be using my fingers."

Her face reddened at that statement. "This is training, nothing more, so yes, are going to be doing this again..."

Natsu's eyes softened. "Training only, right... You're not mines to keep yet..."

"Right... This is training..."

"Then it can't be helped..."

...

...

"Where the hell is Crystal and Natsu?" A leather boot tapped recklessly on polished floor, a loud, annoyed sigh escaped the scarlet haired woman's lips.

"They'll be here soon." Gray reassured her. Juvia nodded.

"Natsu-san and Crystal-chan will be back soon. Juvia knows that Crystal-chan is in alot of pain."

"That is true." Lucy noted. Erza sighed, putting her head down in frustration.

"It's okay, Erza-san." Wendy smiled. "They'll be here soon."

...

The door of the bathroom opened slowly, steam coming out as Crystal stumbled to walk. Her legs and hips kinda hurt, considering their little 'training' they did. Her damp, wet hair clung to her back and shoulders, her face red as well.

The bluenette walked into the kitchen were everyone waited for Natsu and Crystal to arrive to eat breakfast. A trail of wet footprints and water followed behind her.

"Hey guys."

Everyone turned their attention to her, eyes widening. Lucy and Wendy had blushes on their faces.

"Where are your wounds?!"

"How can you walk?!"

"Crystal..." Erza hissed. "I'm glad to see that you're doing fine but please... Tell me, why are you so late to breakfast?"

A light blush tinted her cheeks. "It's-"

"-None of your goddamned business."

Crystal turned her head around, seeing the pink haired man in a towel that covered his lower half, walking towards them with a annoyed look on his face.

"Natsu, I warned you already!" Erza stood up, slamming her hands on the table, alarming everyone.

"But I didn't listen. End of story."

"One of these days, you'll go too far with her." She glared at him, her dark brown orbs piercing into his soul. "And that same day, I'll make you wish you were never born."

With that, Erza walked off, passing him with a cold look on her face as she walked up the polished stairs and up to her bedroom.

"Pssh." Natsu scoffed. "Come on Chrissy." He walked off as well.

"Well um..." Crystal nervously laughed. "I'll go change..."

...

11:00pm

...

Soft and gentle moans came from Crystal and Natsu's bedroom, the scarlet haired woman's bedroom was right next to theirs. She heard all of it. It made her blood boil.

Erza always considered Gray, Natsu and Crystal as her little siblings. She always wanted was was best for them but what Natsu was doing to Crystal...

Manipulating her... Making her do all these embarrassing things... It didn't feel right. It was always this time of year that made the pinkette like this. So... Desperate and needy for sexual affection.

This happened when Crystal left. With Lisanna, but it wasn't so strong for him to do anything. Also with Lucy but his urges wasn't so strong for him to do anything either.

But for Crystal... It just seems he can't fight back...

And that is what made her angry. The day he went over the edge, when Crystal didn't give consent...

Is the day Erza will snap.

Crystal was always considered a little sister to her. A precious, little sister. After all the things she's been through, even when Erza wasn't there to protect her, she still pulled through. Such a strong person, one of the stronest souls Erza has every seen.

She wanted to maintain that.

...

"Ahhh... Aaaaaahhh..."

"Easy Chrissy..."

"Natsuuuuu... Mmmphhhh..."

The pinkette's finger circled her clit, coating it in her own juices before going back in, pumping in and out at a rapid pace through her underwear. Crystal was on her side and Natsu was behind her, one of his hands groping her plump breasts.

She didn't want to make alot of noise, she wanted to be as quiet as possible. But alas, she couldn't substain her moans of pleasure.

"Natsuuu... Please... Ahhhh..."

"Yes? What do you want..?"

"Deeeeeeper... I want... Ahhh, deeper..."

He smirked, pulling his finger out from her core, white fluid going down his digit. The pinkette placed Crystal on all fours, pulling down her black, lacy panty and staring in awe at her. Natsu pulled down hie pants and boxers, his erection bouncing out.

He rubbed the tip of his cock at her quivering folds, letting it soak up some of her come that was already dripping from her entrance.

"Ready...?" He angled his dick carefully by her hole.

"Natsuuu... T-this is practice... Right?"

Her words cut through his haze of lust, stopping his actions.

This wasn't practice. It was him taking advantage of her. Saying that it was practice when he knew all about these things already. Natsu just wanted to satisfy his needs with her.

"Yes... This is practice."

'Stop lying with those words...' His heart said but his mind was another.

"Then... G-go ahead, go slow since this is my first t-time..."

"First time.." He repeated. Natsu didn't want this to be her first time with him like this! She wasn't even his! Natsu desperately wanted to fight the urge of ramming into her and fuck her senseless.

He had to...

Before he could make a decision, a knock came to the door, interrupting the couple.

"C-crystal-chan?" A small voice called out. "Can you come outside? The others are calling you and Natsu-san..."

Natsu's hand clamped over her mouth, preventing her from making any noises as he eased himself inside her slowly. Her eyes widened, her moans muffled from the palm of his hand. His other hand holding her by her hip.

"Wendy? Crystal's sleeping. I'm going to sleep myself, just talk from there." The pinkette went slowly out of her, letting the tip of his cock dance outside before thrusting in deeply.

A long, drawn out moan escaped the bluenette's lips, not going unheard by the handsome man behind her. Her glasses fell off her face and unto the bed.

Natsu began to rock his hips against the sky haired maiden with long, deep strokes that made her quiver beneath him. Her walls clinched and squeezed around the hot organ inside her, Natsu held back his moans.

"W-well... We found this little girl downstairs, she was going through the fridge. She sneaked in from the window, when we asked, she said she was homeless and was hungry..."

Natsu stopped, his cock pulsing inside her.

"I'm listening..."

"She didn't want to talk to any of us after that so Lucy-san suggested that you and Crystal-chan might be able to talk to her... T-that's all."

"Okay Wendy, give us a few minutes and we'll be right down."

The pink haired assassin waited to hear her light footsteps leave from the door. He sniffed the air, he only smelled Crystal's scent, no Erza, no Wendy, nobody. Only her sweet... Intoxicating scent. He removed his hand from her mouth.

Natsu pulled out of her warm sheath and thrusted back in with a long, deep stroke. Crystal moaned, clawing the bedsheets beneath her.

"Natsuuuu... Ahhh... We have to... Oh God... Go downstairs... Mmmmm..." She placed her face in the bed to muffle her embarrassing sounds that escaped her pink, swollen lips.

"They can wait a few minutes... This is training, this is important... Tell me how it feels to have my cock inside of you..."

He went closer to her ear. "Deep... Inside of you..."

"Naaatsuuuu..." Crystal moaned helplessly.

"Is this deep enough for you?" He circled his hips while fully seated inside her, caressing her ends of ends and making her legs wobble with the overwhelming feeling of fullness. Natsu thrust into her hard, her mouth drop open with another long, drawn out moan.

"Mmmm... Do you like the feeling of me fucking you... Crystal?" He whispered hotly against her ear, nipping the soft lobe between his sharp canines.

"How does it feel...?"

"Ahhhh... Mmmm... S-so... Fucking... Good... I love the feeling of your hot cock...mpphhhh... Pulsing inside... Aaaaaahhh... Me... Natsu..." Even Crystal blushed at her own words. She still thought this was training, she had to be completely honest.

Natsu smirked. "That's what I like to here..."

"I'm resisting the urge to fuck you senseless... Fuck you so fast and hard that you won't remember how to walk..." One of his hands seeked to find her drowning clit, he rubbed over with with the pad of his thumb. Crystal moaned loudly but not loud enough to let the others hear.

"But you'd like that... Wouldn't you?" He snapped his hips hard. "You love my cock, don't you?"

"Ahhhhh... Haaaahhhh... Ummmmpphh..."

"Answer me.." He rubbed his thumb faster. "Answer me or else I'll fuck you till you're numb."

"I'll deny you release..."

"Banging into you over... and ahhh... Over... Again..."

"Pleasssseeee..."

"Just say it... Beg for it... Moan for it..." Natsu's lips brushed against her neck, kissing it gently.

"Natsuuuu... Please... Just fuck me... Hard and Rough... Ahhhhhh, over and... Over... Deeppppp inside me, make me come all over you... As your trainer, I demand... Uhhhnnn, you to... D-do... Ahhhh, that..."

Natsu smirked, "All you had to do was ask, you're gonna come for me..."

With that, he slammed himself right back into her making the bluenette shriek at the sudden entry. He pounded into her core roughly, her mouth gapping, short gasps and moans escaping her pink lips as she arched her back high.

"N-natsu! Uuuhhhh! Fuuuuckk! Ahhhhh! I c-can'ttt!"

"You can and you fucking will!" He thrusted into her sex, his thighs slapping loudly against her ass.

"Ahhhh!"

"You know I won't stop until you give me what I want."

"Naaaatsuuu!" She yelled between gritted teeth, clawing unto the bed covers below. This was wayyy too much for the bluenette to handle, this could drive her over the edge.

"Naatsuuuu! We- Ahhhh! We have to- Oh God! Fuck yes! Hit that spot! Fuck yessss, ohhh yesss! Ahhhhhhhh!" Her tongue hung out of her mouth, drool dripping down her chin. Her come trailing down her thighs and pooling down into the bedsheets below. Natsu obliged, ramming that same spot that made her moans louder by the second.

"Fuck, Crystal... Do you know how hot you sound?" He groaned as he was getting closer to his climax. Crystal's walls attempted to squeeze the seed from the thick, hot organ buried deep inside her, that made a loud squelching sound which made the two groan.

"Ahh! I'm coming!" They both yelled, Natsu pulled out, Crystal's love juices squirting everywhere as her body trembled and quaked, her eyes at the back of her head, a large, relieving smile on her face.

Not soon after, long, thick ropes of semen came out from the pinkette's dick, squirting it all over her huge, plump ass. The bluenette groaned at the hotness, his semen dripping down her ass and down her thighs.

"So hot..." Crystal whispered.

"Come on, let's go..."

"I can't... Feel my legs..."

Natsu smirked. "Don't worry, I'll carry you."

A red blush came to Crystal's pale cheeks. "But... How can you be so calm after..."

"After?" He mimicked.

"That..." She emphasized with her finger.

"What are you babbling on about weirdo?"

Her pink lips turned into a childish pout. "Now you're just playing dumb, you just want me to say it because it gets me embarrassed..."

He grinned, his pearly, white fangs showing. "That's because you're cute when you blush."

...

"Took you two long enough." Erza had her hands on her hips, narrowing her eyes at the two. Natsu bowed apologetically with Crystal on his back.

"Sorry Erza."

"It's fine, now, go see if you can talk to her." The scarlet haired woman pointed to the little girl who was in a corner, munching on a piece of bread. Natsu approached the girl slowly, trying not to scare her away.

The girl had light brown hair with ocean blue and green eyes. She wore a purple jacket which had dirt on it, some holes in it as well. A ripped up jeans and her body had dirt on it as well. Natsu placed Crystal down to walk on her own.

She walked slowly, she kneeled down before the girl.

"Hello there." She greeted sweetly with a gentle smile. The girl turned to look at her, eating what was left of the bread.

"U-um... H-hello..."

"What's your name, sweetie?"

The girl fumbled with her words, playing with her fingers. "Yura... Y-yurachiiro..."

"Yurachiiro? That's a pretty name, dear."

Natsu felt a smile coming to his face.

"So, she can cook, she can fight, she's good with children. Waifu material." He thought in his mind.

Crystal inched closer to the girl. "Can you tell me why you were here, dear?"

"U-um..." Her face reddened. "I was hungry... All the other houses didn't give me any food... I-I was just hungry! I didn't mean to steal! I haven't eaten in days..." Yura frowned. Crystal inched a little closer.

"Where's your mommy and daddy?"

Tears pooled in the brunette's eyes. "I never had a daddy... A-and Mommy told me to wait somewhere..." Tears streamed down her dirty face. "That was two years ago..."

Everyone gasped. Crystal's eyes widened. Who could do something like that? Abandoning their child?! Crystal never forgave people who did that, whoever does that are sick, twisted fucks. Crystal embraced the crying girl, caressing her head. Yura started to cry more, wailing loudly as she clung to Crystal's shirt.

"It's okay, Yura. We'll take you to a place where you'll find a new Mommy..." Crystal smiled softly. "But in the meantime, you'll stay here, with me."

"R-really?"

"Yes... Really." Crystal pulled away from the hug. "My name is Crystal, and I'll be your Mommy for the while..."

Yura sadly smiled. "I'd like that... Very much..."

Crystal giggled. "Me too."

Crystal stood up shakily on her two feet, managing to balance properly. She bent down and picked Yura up, attempting to walk straight. Gray laughed at her along with little giggles from Lucy.

"You look like a penguin." Natsu chuckled. Crystal shot him a death stare.

"Your fault I'm walking like this..." She mumbled with a light blush on her cheek, walking out the kitchen and heading towards the bathroom.

...

"Bubbles! Yayyy!" The brunette splashed around in the soapy bath water, playing with the bubbles. Crystal smiled at her.

"More bubbles!" Yura cheered. Crystal got the sponge and washed down Yura's body gently. Scrubbing off all the dirt and grime off her lightly tanned skin.

"You know, Yura, you didn't tell me how old are you..."

"I'm seven!" She beamed, putting her arms up so Crystal can scrub underneath there.

"At fucking five years old, her mother left her?" Crystal said in her mind, rolling her eyes. "Bastard."

"After your bath, we'll get you something to eat."

"That sounds good!" Yura splashed some of the water unto Crystal's face, giggling. Crystal smirked, splashing water on her as well.

The two laughed.

...

8:00pm.

...

The bluenette tucked Yura in bed in a room next to theirs, watching the little girl sleep peacefully. Crystal couldn't help but smile, this was her first time doing this sort of thing, afterall. Yura was a little ball of light.

Who would want to abandon her?

"Hey."

Crystal turned her head towards the source of the voice. A pink haired man leaning against the door, a sweatpants on with no shirt.

"Hey Natsu."

"Yura's sleeping?"

"Yeah..." Crystal walked away from the bed, turning off the light and going into their room. She plopped down unto the bed, sighing loudly.

"I'm tired..." Crystal groaned. Natsu sat next to her, pushing up her light blue glasses.

"Taking care of a child... Is hard work. But you nailed it, Chrissy. I'm proud of you." Natsu grinned, moving some hair away from her face. A light blush came to her face as her eyes grew heavy.

"Get some sleep... You earned it."

...

...

"FUCKING HELL!" A voice boomed. "NATSU DRAGNEEL THINKS HE CAN FUCK WITH ME?! TASKIMADA!?"

"Master, calm down..." The dark blue haired man said, trying to calm him down.

"SHUT THE FUCK UP, MIDORIMA! THIS WAS YOUR FAULT IN THE FIRST PLACE!"

"I know, I take full responsibility for my actions..."

Taskimada sighed, shaking his head. "Fine, he wants to play that way? Fine, let's play." He looked through the drawers of his desk, looking for a specific book.

"Oh right... That book is back in Japan... Fiore... Maiobushi..." Taskimads grinned. "Someone lives there... Guess I'll have some fun after all."

"Yes, The Hojohana Family." Midorima nodded. Taskimada laughed.

"Pack my bags, we're taking a pit stop to Japan."

...

"Just you wait, Natsu... I'll find that book and give you hell..."
