Author's note: So this is my most recent plot bunny. It is a totally complete, very large three chapter one shot. I'm actually posting it all at once - go me! I wrote it start to finish without stopping, so I figure it should be posted so everyone can read it that way.

I love Soul Eater, and the dynamic between the characters is awesome. With that in mind, I have to place this warning. This is fully my normal M-rated fare. Completely NSFW...hell, I should just label it as not safe for anyone, read at your own risk. *chuckles* Um...I think that's all I have to say. I give you, story. Have fun!

She couldn't sleep. It wasn't unusual lately. With careful movements she slid out of her weapon's warm embrace and dressed quietly, her workout shorts and t-shirt sliding over her skin easily. Lacing up her shoes she turned back to the bed. Soul looks so sweet when he sleeps, she thought. She tucked the cover around him and smiled as he snuggled deeper under the covers, reaching out in his sleep to pull her pillow to him. She placed a soft kiss on his forehead and headed out of their apartment, knowing that if he woke up he would know she'd gone to the Academy's gym to work out. She always got restless closer to her birthday, ever since she was little. It hadn't changed as she got older. Now, though, she didn't have to lay in her bed and stare at the ceiling. She was old enough to go out and do something when the urge hit, and lately that something was a bit of exercise or yoga...or sex. Since she and Soul had officially become a couple, she'd found that her restlessness could usually be assuaged by a rough-and-tumble romp in bed – or couch, or floor, whatever. He'd happily awakened her libidinous side, and she loved it. She loved him. They were an incredible couple, and remarkable (in her eyes) in that neither one of them was the jealous type. She remembered the first time she'd walked in on Soul and Tsubaki. She'd often thought that if she ever caught her mate cheating like her Papa had done to her mother, she'd go berserk and probably kill him. However, all she could do was stand there, stunned. Tsubaki noticed her first and instead of seeming ashamed or embarrassed, simply raised her hand to the wide-eyed meister. She never could explain what caused her to step forward and take the female weapon's hand, but that night proved to her beyond the shadow of a doubt that Soul loved her and her alone. It also proved that love and lust were two separate things. It was a concept that Maka had struggled with for months after that night, feeling as though her entire world had turned on its head. She remembered how she had stopped talking to everyone, how she had completely withdrawn. She had started spending all of her time in the library, often not venturing home for days on end. Kid had been the one to find her there, to sit and talk with her and let her spew out her confused thoughts and feelings and impressions. She hadn't felt judged or scorned. The reaper had listened, letting her cry on his shoulder when she needed it, letting her take out her rage on him in the back corner of the library she'd hidden herself in. And when she was exhausted, worn, he'd held her and kissed her hair and asked her a question.

"Do you doubt that Soul loves you?"

"No!" she said vehemently, though keeping her voice quiet.

"Do you doubt that you love him?"

"Never," she spat just as fervently. He turned her face to meet his.

"Then what is the problem? You will never leave him, nor he you. So if you find something you both enjoy that hurts no one, what's the harm?"

"But, my Papa -"

"Is not Soul," he said softly. And she realized he was right. She sighed and curled up against his chest, feeling weary.

"How did you get so smart about all this?" she asked his collarbone. She felt him chuckle.

"I am a meister with two very...active...weapons," he replied smoothly. Catching his insinuation she sat upright, knowing she looked shocked but unable to school her expression.

"You mean you...and Liz and Patty..." He laughed then, a warm sound, and gently squeezed her hand.

"Yes."

"And...it works for you? There's no...you don't feel..?" She couldn't quite put into words what she wanted to ask but he understood anyway.

"It's a situation that works for all of us."

"But...how..?"

"You should know. Tsubaki says you're quite the agile tigress," he teased gently, and she felt herself turn bright red. His dual-tone golden eyes were warm and amused as she sputtered. Eventually, though, she started laughing, the absurdity of the situation finally sinking in. Kid laughed with her, holding her as she let go of the tension and the strain she'd carried like a backpack since the entire thing started. And when she wound down he kissed her forehead and urged her to stand up.

"Go find Soul," he said, climbing gracefully to his feet as well. "He's been a mess without you." She felt guilt settle in, but he brushed a finger across her lips. "You had to figure things out. He understands. It's okay. But he's worried that you might not love him now, and nothing any of us have said has been able to convince him otherwise."

"Thank you, Kid," she whispered. He kissed her forehead once more.

"Anytime, Maka. Now, go find your man and give him the ride of his life." She flushed bright red again, and he laughed out loud as he turned her around and sent her on her way.

Things had been a little rocky when she'd gotten home. The house was a mess, and her partner, her love, was curled up in a ball in the center of the bed they'd barely begun to share. He didn't uncurl when she sat down, but when she whispered his name he sat up with a snap of motion that nearly threw her off the bed. He stared at her, jaw dropped and crimson eyes wide with fear and hope and love, and she couldn't find any words. She thought she'd take Kid's advice, and once Soul realized she was serious things heated up quickly. Afterward as they lay together she noticed he was crying.

"I'm so sorry, Maka," he whimpered, clinging to her like he thought she would run away again. "I'm so sorry." She shushed him and held him close.

"No, I'm the one that's sorry. I didn't know...I didn't understand..." The rest of the night and most of the next day they spent talking quietly and making love, confirming their bond with each other in every way they could. The following evening Kid had invited everyone to his place for dinner, and though Maka was still a bit hesitant at seeing Tsubaki again, it turned out her fears were for naught. Walking in and seeing the beautiful weapon sitting on the couch beside Black Star, seeing the wariness and worry in the other girl's eyes, Maka realized she was completely okay with everything. To everyone's shock she didn't say a word. Instead she walked up to Tsubaki, leaned over, and kissed her gently, thoroughly. All was forgiven – all was fine. And Maka found herself introduced to a wonderful world of love and friendship she'd never imagined before.

Over the coming months the blond meister had the extreme pleasure of expanding her sexual horizons in ways she'd never even realized were possible. The group was strong, devoted to one another, and before long she knew that this was the family, the love, she'd always been waiting for. As lovers they were all wonderful, and the bonds they shared in and out of bed made her feel complete in every way. She remembered the first time they'd all spent a full weekend together, learning and exploring and amazing each other. The following morning Stein's class had been focusing on ways to improve group soul resonance. And when it came time for her group to try, Maka had felt such a surge of perfect joining that she nearly wept. The force of their resonance, the flawlessness of it, was so strong it had knocked their teacher off of his feet and he sprawled by the foot of a tree regarding them with something akin to awe. They had received the highest possible grade, and after class he'd asked an elated Maka to stick around for a moment. She walked up to his desk as he pulled his chair out, spinning it around and straddling it gracefully while regarding her with inquisitiveness in his olive eyes.

"I'm sure I recall a certain group that seemed to combust every time they attempted to resonate together. I have a hard time believing that this is the same group that blew me across a clearing today. Care to explain?" Maka, faced with the curiosity of her most respected teacher, couldn't bring herself to say anything. He raised an eyebrow at her as she silently turned red and began to look at the floor, the desks, anywhere but into his eyes. "Maka?" he asked again, the gentle command in his voice calling to her obedient schoolgirl self, and she finally lifted her eyes to his.

"We...we're all...all of us...well..." She saw the flash of surprised understanding in her teacher's eyes, followed by a quicker burst of something else she couldn't define.

"I see," he said thoughtfully, pulling out a cigarette and lighting it up all without taking his eyes from the blushing girl in front of him. "You must all...work...well together, for it to have had such an incredible affect on your resonance." Unable to speak she simply nodded and watched as his long fingers brought the cigarette to his lips for a drag before moving it away again. They stood in silence for a moment, Maka unwillingly fascinated by the motions of his hands as he smoked and the professor regarding her with the type of interest he usually reserved for specimens on his dissection table.

"I don't think you should bring this up with your father," he said finally and she gaped at him. He let his lips twitch upwards in a smirk. "He's impossible to deal with as it is where you are concerned. I don't want to think how difficult it would be to pull his head out of his ass if he found out his innocent baby was anything but innocent." Somehow his words made Maka shiver. Something about the way he said them, the way he looked at her, as though he would love to dissect her mind, sent a warm quiver down her spine.

"I...I wasn't planning on it," she murmured. For another moment they stayed there, not moving, each regarding the other. Finally he shifted his chair.

"Very good. However, I am interested in this phenomenon. As you are the most dedicated student in your group, I would like you to write an essay on how you think your current situation has improved your group soul resonance abilities. I don't want specifics -" he was quick to assure the wide-eyed meister "- but generalities would be of interest. This is not something that has been documented to my knowledge. As I know I can trust you with this assignment, I will only ask that you turn it in before the end of the school year. Have a nice evening." He stood up from his chair and strode out of the room, leaving Maka to stand alone by the desk and ask herself what the hell had just happened.

Despite her initial reservations she found she actually enjoyed the assignment. It was fascinating to try and determine which aspects of her group's new-found intimacy had what effects on their ability to resonate together. Two weeks after her talk with the professor, she stayed after class as her friends left. Once the room was empty save for her and Stein, she calmly walked up to his desk and pulled her essay from her bag. He blinked at her, momentarily nonplussed, before taking the multi-page document from her slender hand.

"I included as much as I could without going into specific detail, just as you asked. Really, once I started thinking about it and figuring it out, it became so fascinating, I'm afraid I might have made the assignment rather longer than I'd planned." She was watching as he ruffled through the papers, glancing here and there, occasionally skimming a page. He finally set the papers in front of him and looked up at her.

"And have you learned anything?"

"Yes, I have," she said in a firm, quiet voice. He nodded.

"Very good. Have a nice weekend." Recognizing a dismissal, she left the room and went to join her friends. He never brought up the assignment after that and neither did she, but she did notice her midterm grade included quite a high number of extra credit points.

Her trip down memory lane ended as she reached the front steps of Shibusen. It was early, not even two in the morning, and she took the stairs two and three at a time, reaching the top without even breathing hard. Her destination was as familiar to her as her own home. However, when she walked into the back gymnasium, entering from the door behind the bleachers, she realized the gym was already occupied. Some instinct had her drop to her knees behind the bleachers and look out to see who it was. And then all she could do was stare.

The stitches and scars notwithstanding, her professor was in fantastic shape. His muscles were defined, strong, his skin glistening with a fine sheen of sweat as he moved. She knew Professor Stein was impressive – rumor had it he was the strongest meister to ever graduate the Academy. And she'd seen a hint of that strength in the church when he and her father had fought against the Demon Blade and Crona. But to watch him now, running through a solo kata that was so advanced it made her head hurt, clad in nothing but a pair of drawstring pants that rested low on his hips...Maka felt almost faint. Holy shit, she thought to herself. Who knew he was so...gorgeous? She was frozen in place watching the vision before her, trying hard not to let her breathing become audible. The way he moved, the fluidity of his kicks and punches...she had a sudden flash to her first meeting with the enigmatic man, when he had held her and traced his fingers over her skin, his marker leaving black streaks to designate places he had wanted to slice into. Then, she had been terrified and not a little angry. Now, though, the things she hadn't noticed while she was held captive – things like how warm he was, how solid the body was that she had been dragged so tightly against, the unbending strength in his grip – flooded over her in a torrent that left her spinning and very much aroused. She gazed in breathless rapture as he practiced, a roundhouse kick leading into a back handspring that flowed effortlessly into a series of deft, lethal-looking fist strikes making her moan softly. If he was this precise, this skilled at fighting, how would he be in bed? Maka stifled a groan at the thought, desperately trying to clear her mind. He was her TEACHER. He was her FATHER'S FRIEND. So why was she crouching behind bleachers staring at the intensely focused meister working out and using all of her willpower to not plunge her hand between her legs and bring herself off while she watched him? Dammit, she thought. I should have stayed at home and woken Soul up. Or gone to Kid's or Black Star's. She watched as his pants shifted an inch or so lower and bit her lip almost hard enough to draw blood. He paused imperceptibly for a moment before continuing and she realized with something akin to mortified shock that he knew she was there. How could she have forgotten his ability to sense souls as well? And yet he didn't stop practicing; aside from that split second pause there was no indication that he knew he wasn't alone. Without her conscious intent her fingers began tracing small patterns over her bare thighs. She stopped thinking she could leave...surrendered completely to the fact that she was a voyeuristic pervert that was about to stroke herself to orgasm while watching her professor work out. Having thus given up the battle, she wasted no time in shifting her hand down past her waistband until her fingers could swipe over her already sopping core, her other hand reaching under her shirt to pluck and tug at her already hard nipples. As though in tandem, his attacks and movements gained in intensity while her fingers rubbed harder, plunged deeper. Time slipped away as she knelt in her hidden spot. She was so close, so very close...her climax hit with a shudder and a cry quickly stifled by biting down on her other hand as the one between her legs thrust as deep as it could go. She slumped to the ground in a near-faint, the world going dim and fuzzy for a moment as all of the blood in her body drained to the throbbing pulse between her legs. She knew she was panting, and some distant part of her tried to convince her to keep it quiet, but she just lay there unmoving save for the shudders that wracked her slim frame as her eyes fluttered shut.

By the time she came back around, she was alone in the gym and the lights had been turned off. Wait – not alone. Finally taking her hand out of her shorts she sat up and looked directly into the eyes of her partner, the red orbs staring back with a combination of lust and surprise.

"How...how long have you been here?" she whispered. He smiled, his sharp teeth gleaming.

"Since you first started to jack yourself off while watching our esteemed professor." She moaned, mortified, and he laughed. "Who would have thought you'd ever loosen up that far?" He leaned over her, lifting her still-damp fingers to his lips and licking them gently, causing her to moan as her libido came back full force. "Little Maka Albarn, perfect student and skilled meister...kneeling behind the bleachers fingering her own pussy to the sight of her teacher working out?" He'd moved his attention to her neck, the points of his teeth grazing her skin. She moaned and arched against him.

"Dammit, Soul, just fuck me already!" she growled. He pulled back, blinking in mock surprise.

"Such language from such an innocent," he murmured, and she remembered Stein calling her the same thing, the recollection making her wet.

"Soul..." she whined, but he was already pushing her pants down so she could kick them off while he worked on freeing his swollen rod from his own pants. With the intuition that made him such a magnificent partner, he knew she didn't want foreplay and since he was more than ready – hell, he'd been ready since he'd walked in and seen her slack-jawed and moaning while she frigged herself – he dropped to his knees, coaxed her ankles over his shoulders, and plunged into her. It was hot, hard, and quick, Maka squealing and writhing her way through an orgasm almost immediately.

"So wet, baby...watching Stein really did it for you, huh?" he murmured in her ear. "I'll admit, it would be hot to watch him fuck you." She moaned and arched against him and he smiled, taking a few moments to nip and suck at her nipples before pulling out and urging her onto all fours. He slid back inside her furnace-hot slit with a moan. "You'd like that, wouldn't you? Maybe he'd take you like this, on your hands and knees as he mounted you." He felt her clamp down on his cock hard, heard her gasping and crying that signaled another climax, and he pumped into her steadily, riding it out while she moaned. Her arms gave out and she dropped down, resting her head on her forearms. The motion tilted her hips and he slammed in deeper, loving the squeaks and yelps she made when he bottomed out against her cervix. A few more deep, hard thrusts and he was coming, filling her with his warm seed while she moaned and shuddered with aftershocks. He pulled out and dropped to the floor, cradling her in his arms while she quaked. The only sounds for a long time were their breathing and the occasional shift of skin against wood as they moved to more comfortable positions. She buried her face against his neck and he could tell she was embarrassed.

"What's wrong, Maka?" he asked gently, stroking her tangled hair.

"I feel so...dirty. I shouldn't be thinking about him like that. How am I ever going to face him in class?" she moaned, humiliated. Soul cuddled his meister and brushed his lips over her hair. "And YOU!" she said, pulling back and fixing him with a glare. "You certainly didn't help, whispering all that stuff." Soul grinned unrepentantly.

"Aww, what's the matter? Even I had to admit the guy is hot. And it would definitely be sexy watching the two of you." Maka moaned and wished for a book so she could Maka-chop him. Soul, meanwhile, just laid there plotting silently and chuckling out loud.

Stein was finishing up some last-minute paperwork for the next day when Soul walked into the classroom. The teacher paused and looked up to regard his visitor, blinking in surprise when the white-haired weapon turned and engaged the door lock.

"Yes, Soul? Can I help you?"

"Actually, it's Maka. I think she needs your...help." The pause was almost nonexistent but Stein caught it anyway and it piqued his curiosity. He pushed the pile of graded papers to the side of his desk and gestured for Soul to pull up a chair.

"What about Maka?" the older man asked.

"She fantasizes about you. And I think it would be good for you two to have sex."

A pin dropping to the floor would have sounded like a gunshot in the silence that pervaded the classroom. The professor stared blankly at the young man. Soul, in contrast, leaned back into his chair with a smile that was half smug.

"What..?" was all Stein could manage to get out, feeling completely lost. The younger man kicked his feet up and rested them on the desk, leaning back so far he tilted his chair onto two legs, all without dropping eye contact with his prey.

"A couple nights ago, Maka was having trouble sleeping, so she came to school to work out in the gym. But you were already here working out. I came in just in time to see my girlfriend stroke herself to orgasm while watching you. She actually passed out. I've never seen that before. And mentioning your name while we're together sets her off like nothing I've ever seen. But she's too shy to say anything, so I figured it would be up to me. You can't tell me the idea isn't a little hot," Soul said with a knowing smirk. Stein's mind flashed back to that extra credit assignment she'd turned in, to the non-details she'd added that had his vivid imagination racing. He'd felt horrible about getting turned on by his friend's daughter, though, and forced the thoughts to the back of his mind, refusing to let them see the light of day. In the wake of Soul's blunt statements, however, they all flooded back with enough force that Stein would have dropped to his knees if he weren't already sitting down. He must have gasped or choked, because his visitor's smile grew positively predatory, an impression enhanced by the boy's mouthful of sharp teeth. He closed his eyes to gather his thoughts. He should, by all rights, throw the impudent brat out. He should bring it up with Lord Death. The entire situation was so far outside any possible bounds of propriety that it was laughable. And yet...

...Maka, with her smooth skin and long legs that he would have had to be dead not to notice – those large emerald eyes that always held so much respect, what would they look like filled with ecstasy? - that willowy, slender body, so flexible, so pliant, as anyone could see when she fought, and the positions he was sure she could bend into –

...Maka, his best and brightest student, already miles ahead of anything the school had seen save himself – his best friend's only child, the light of Spirit's life – the leader of the most powerfully resonant group he'd ever seen – Lord Death's personal favorite student with the exception of his own offspring -

...Maka, looking so blissfully pure when he knew, had read in her own words, how false that statement was – that brilliant, studious mind, always looking to learn, to grow, to experience more – and oh, the things he could teach her -

Soul sat calmly in his chair watching the emotions flit across his teacher's face. He wanted to laugh when Stein began to turn the screw in his head, his eyes flitting back and forth so quickly anyone less familiar with his mannerisms would think he'd gone mad. But the weapon knew he had to be cool. If this crazy plan of his was going to work, he had to be the epitome of cool. He had to lead Stein to the water, but let the man decide to quench his thirst on his own. And Soul could tell the older man was thirsty. If the idea had held no appeal for the professor whatsoever, he would have already been sent out of the classroom, and likely been called to Lord Death's room for a little talk. Instead the man had withdrawn entirely within his own mind. Soul doubted the teacher even remembered his presence. Finally after what seemed like hours green eyes met red.

"You are evil," Stein muttered under his breath causing the younger man to laugh.

"That I just might be – but I'm also a man who wants his love to be as happy as she can possibly be. And right now it looks like the thing that will satisfy her the most is having you between her thighs. So whaddaya say?" He knew he was being frank, but he had to admit that his plans weren't only for Maka's benefit. It seemed that the older man came to that conclusion as well. He fixed Soul with a knowing gaze.

"And what would you get from all of this?" Stein asked smoothly. Soul shrugged and smiled wickedly.

"I want to watch." He barked a laugh at the expression on Stein's face. "I know you know about our group. Maka left her essay on her desk once and I found it while I was cleaning up. So I know you know that we've all got a nice little arrangement going. I know you asked her to keep specific details out. But I also know that you're a smart man, and I'm sure you can infer that, in our little circle, we weapons are more likely to be voyeuristic.

"Maka is amazing in bed. I've never felt anything like it. But she is also the only woman I will ever love, and that means that if it makes her happy to try out new things, I support her wholeheartedly. Once she broke out of her shell, I found I get off on watching her with others, watching them enjoy her skills and willingness. I watched you while you worked out. I can see why she was so turned on. And I have to say that the thought of you screwing my petite little Maka until she screams holds a huge amount of appeal for me." Stein looked like someone had hit him. Soul considered that his cue to leave. Standing up he began to walk away, his steps carefully nonchalant. As he approached the door he paused, speaking over his shoulder.

"Next Saturday is Maka's 18th birthday. Let me know sometime before then if you think you might like to be her present. See you tomorrow." He walked out of the classroom without another word, not needing to see the crumpled, stunned man at the desk to know that he'd be asked to stay after and talk with the good professor before too many days had passed. Maka was going to have one spectacular birthday.
