Chapter One:
Swim

Location drop, now
Pedal to the floor like you running from the cops now
Oh, what a cop-out
You picked a dance with the devil and you lucked out

When Sirius woke up that morning, going to History of Magic wasn't on the agenda. It was the class he only went to went to the moment Binns got on him about assignments or threatened a detention too close to the full moon. There were a million better ways to spend his time and he saw one of them sitting next to the only empty seat in the room. He followed the row back to the corner where he spotted Amelia Bones and slipped into the seat next to her. "Bones."

"I don't know if I should be annoyed you are late or surprised you actually showed up," Amelia said without looking up from her book. She tried, but she couldn't fight the smirk quirking in the corner of her lips as she felt his hand sliding along the hem of her skirt. She had gotten caught in Potions and stuck in the back of the room instead of her usual front-row desk, but this addition….she could use to make up for that. Maintaining her composure, she looked over at him. "I'm going with surprised. I didn't think you knew where this class was, Black."

They had hooked up before a few times, nothing recently, but enough for Sirius to feel right at home sliding his hand up her thigh without a conversation. His fingers slipped under the lace of her knickers, pulling it down just enough to get beneath it without causing any suspicion. The class was a waste of both of their time, but the time for distractions was beautiful. She bit her lip, rocking forward once as she got into a more comfortable position.

Sirius leaned forward slightly, his fingers sliding along her slit, increasing his pressure just a little as he brushed over her clit. "I know a few things, Bones," he whispered as Binns began lecturing at the front of the classroom. His fingers traced lower before teasing her entrance before sliding one finger inside while his thumb brushed over her clit. He knew she wouldn't make a noise and the professor had no reason to venture back there if she stuck to it. He wasn't going to make it easy on her, especially as the class failed to answer the question Binns was posing to them.

"The Giant Wars ran from 1867 to 1869," Amelia answered without thinking about it.

"For every question you answer correctly, you will be rewarded," he whispered, his thumb making swift circles over her clit.

Amelia shot him a look, loving the challenge he gave her. If there was one thing she loved move than sex, it was being right and Sirius was combining the two deliciously. He started shifting and she nearly lost her train of thought as her fingers wrapped around the edge of the table, but the defining silence in the room as others struggled not to answer brought it to her attention on the second question. "The Ministry turned Gringotts over to Goblin control in 1865."

"Good," Sirius smirked before curling and scissoring his fingers for her. It wasn't aggressive, nothing noticeable, but it was purposeful, and he could feel by the way she was shifting next to him that it was working. He slipped his hand away when she finished before slipping out the back of the classroom and waiting for her to follow for more.

There was a small part of her that hated herself for going, but she was already too worked up not to and Amelia was going to get what she felt she earned with those answers. She gave it a moment after he left before slipping out of the room. "Tosser," she said when she saw him waiting outside the room.

"And?" His hand slipped down to her hip, leading her into a supply room and closing the door. "I needed you ready."

"You spent half the class fingering me and you thought I might not be ready?" she asked, sliding her knickers down fun under her skirt and stuffing them into her bag.

"I like you better when you're angry." He smirked, unbuckling his belt.

"I'm irresistible in all forms," Amelia told him with a smirk.

"You know what…" he took her hips and turned her, pressing her against the wall. She gasped for him as he flipped her skirt up and mumbled the protection spell before sliding into her. He needed to wipe that cocky smirk off her face, and he knew just how; his hands gripping her hips as he buried himself inside her. He could hear her moaning into the wall and reaching back for his, trying to urge him faster and he knew he made the right decision. "Bones, you might want to hold the wall," he hissed in her ear as he shifted his angle and moved faster.

"If you show me that I need to, I will," Amelia antagonized before he tilted her hips back moved until he heard her panting. Her hand gripped around the storage shelf, gripping it tightly as she bit her lip, trying desperately not to scream as the shelf rattled with every shift of his hips. She shuddered as the orgasm moved through her, clenching and gasping into the wall as she came down from the finish with him.

Sirius groaned before pulling back, taking a beat before he zipped himself back into the trousers. "Always a pleasure, Bones," he said before turning to leave.

"That was good, Sirius. I think you may have finally fucked yourself into second place," she teased, straightening her skirt as her red curls fell over her shoulders. She smirked to herself when she saw him stop. One more second and he would have been out the door, but she knew he couldn't leave after that."

"Second?" he laughed. "Bones, if you want more you could have just asked instead playing your petty little games."

"I'm not playing games; I'm just giving you an honest grade. We like honesty, Sirius. We're very honest people. It's why this little arrangement works. If all I wanted was more, I'd just go coax out number one. Three is a little busy with Red," she wrinkled her nose, crossing her legs as he walked closer to her.

Sirius knew her all too well. Amelia was always playing a game and if he was a more mature man he would have walked away, but he couldn't. He couldn't walk away from such a blatant challenge, especially when it came with such a nice pair of thighs. "James is number three?" he asked, stopping in front of her.

"James is number three," she agreed. "He was two, but that was good and I'm pretty sure he was just using me because I share a few traits with someone else. Not that I mind, I mean, I was just using him because I didn't want to go to Divination. I'm just not into the lovesick thing he's doing right now. So, you are number two, Black. Congratulations."

"Two? Who, dare I ask, is number one? You? Are you the best you've ever had?"

Amelia scoffed, looking up at him. "Even I'm not that vain. Although I think we both know I can do more with my fingers than most people can do with their whole body," she pointed out as she sat on an extra desk. "Your other friend. Lupin, the quiet one. I never expected that from him, but he was..." she bit her lip, "...relentless."

Sirius shrugged, "You're alright, but I won't lie. That is surprising. It must be all that inner turmoil." As he spoke his hand went up her skirt and he said simply, "But I understand you are number one at head, ironically, but everything else shockingly Alecto is better. Maybe it was all that time she was locked up as a child..."

"Something like that. I'm not sure exactly what it is, but he really puts his best foot forward." Her hands didn't move from their place on her lap as he moved in, sliding his hand under her skirt and pressing forward. "Alecto is good at a lot of things. I'm not going to argue with you," she said, "She wasn't locked up that often. She just wants people to think she was so she seems more dangerous. And when did you sleep with Alecto? She yells at me when I go near you, I'm having a hard time believing she went anywhere with you."

"It was the kind of crazy night that was too vivid to repeat." He said calmly, his finger flicking up against her slit. "But to honest, Bones. I really don't care if you believe me. See if you didn't want anything you wouldn't have said a word." He grazed his finger around her clit slowly. "But you stopped me and you are trying to pick a fight from me. And I just adore watching you try."

"I don't doubt it. That sounds like quite the party. Lex has never really been one to discriminate. I'm not saying you are lying; I'm just saying it's an interesting combination." She uncrossed her legs as he moved her fingers in against her, nodding her head as he brushed her skin. "I never said I didn't want anything. You walked away; I wasn't done. I don't see the crime here," she said, her words gaining height near the end of her sentence as he touched her overly sensitive skin. "Are you going to settle up or do I need to go find someone who will?"

Sirius said, "Hmmm." Then his fingers moved faster, and he stood in between her legs. "I suppose I could..." Then he smirked up at her and shoved two fingers inside of her. "What exactly would you like, Bones?"

She let out a surprised whimper as he abruptly pushed two fingers inside her. One of her hands moved to his shoulder, gripping it tightly as his hand moved. Her eyes closed, as he pressed inside of her deeper. "When the first years muck up a charm, you can't hear it outside of this room. I would like to know what else you can't hear outside this room," she said. "I believe that's knowledge we could both benefit from having."

He couldn't even hide his amusement at that point. Sirius pressed down on her waist and curled his fingers up, knowingly and relentlessly. His face was an inch from hers and he licked his bottom lip suggestively. "Bones, I like the way your mind works sometimes." Sirius moved forward and whispered in her ear, "As you wish." He made sure she didn't hear him unzip so when his fingers left her, she would have a thicker, longer surprise.

Amelia let out a yelp as he curled his fingers, her body rising with his as he drew them out once again. She knew what he was doing, but she still didn't like the absence of stimulation. She leaned forward as he slipped out of her, leaning into his shoulder as he unzipped and pressed inside her. "Fuck," she whispered, rolling her hips into his.

"Yeah," Sirius scooped her into his grasp and continued rubbing his hand on her clit while he slowly drew in and out of her.

She bit her lip as he pumped his hips, sucking in a breath as his hand brushed over her. Her sensitive skin heightened each one of his movements and it was taking everything in her to extend it out. She wanted to feel it longer. She wanted him to work for it. She knew that always made things better for them both. She wrapped her legs around his waist, her skirt pooling above her hips and over his hands as he picked her up.

He gripped her ass firmly and quickly spun her around and pinned her against a wall, hiking her up high. Then he quickly ripped open her shirt and with one quick movement unhooked her bra. Sirius then lowered down on her left breast, he took her nipple into his mouth and sucked and rolled his tongue all around.

Amelia let out a sigh as he pinned her against the wall. Her back flattened against the stone as he brought her up higher. "Sirius," she hissed as her buttons went flying across the floor, her shirt quickly joining them on the ground along with her bra. He quickly shut her up as he lowered his mouth to her breast.

"Fine," she sighed, her breath becoming more ragged, "but I'm wearing yours back to the dorm afterward.

His hot breaths scorched her and he said, "Fine."

If she thought that was an insult, she had no idea how men worked at all. Sirius reached up and pinned her arms to the wall shifting his hips up and grazing his teeth down the middle of her chest.

Amelia smirked as he pinned her arms to the wall. Now they were getting somewhere. The moment her body shifted up, the angle changed, plummeting him deeper into her depths and drawing a cry from her tried to meet him thrust for thrust.

Sirius sank deeper and deeper into her until with every movement she was slammed back against the wall. He held her hands back with one hand and gripped onto her hair with the other. Greedily he thrust faster, his mouth settled on her collar bone as she pushed her closer and closer to the edge, before reaching his end. Amelia's moans got louder, echoing off the arches of the Potions Classroom as he slammed her into the wall. Her legs tightened around him the closer she got. Her chest rose and fell with her tempered breaths, holding on if she could before she finally fell over the edge screaming.

Sirius let out a shallow breath as he slipped out of her. His hands gripped her to guide her down to the floor. He steadied her with a hand to her shoulder before he slowly unbuttoned his shirt.

Very carefully, Amelia placed her heels back on the ground, her hand gripping the wall as she found her balance. "Thank you," Amelia said, taking the shirt and pulling it over her head. She buttoned most of it before taking a pin from her hair and pulling it back, folding it carefully behind her so she could make the oversized shirt a bit more fitted. She left the top three buttons unbuttoned, leaving the blue tie handing in the middle as she adjusted the robe back over the outfit so she could go to Arithmancy. She made it through the next class and changed from the oversized men's shirt into one of her own before making her way into the Great Hall for lunch.

Amelia never made a habit of repeating too many of her evenings. She had an understanding with herself; getting too comfortable with anyone person was a sure-fire way to complicate things and unless it was Politics or Arithmancy, she didn't do complicated. Teenage boys got attached, especially when she made a point to not be interested, so repeating would only cause them confusion. Fortunately, there were a few that didn't mine her dissipating interest in between meetings and Sirius had made the top of that list. Her lip quirked into a small smirk when she saw him approaching the Ravenclaw table in the Great Hall.

"You still have my shirt," he whispered in her ear as he slipped behind her.

"I put it in the pile with the others," she told him, biting her lip. "If you want it back, you'll have to come to my room and tell me which one it is."

"Whenever you're ready," he told her as he backed up.

"So demanding," she said, looking up at him with a smirk. She finished the pumpkin juice in her glass before pushing herself up from the table and smoothing down her skirt. "You're going to earn it back." Her red curls fell over her shoulders as she spoke, looking back at him before she started to walk him out of the Great Hall.

Sirius rolled his eyes. "Earn it?" he scoffed, "I'll think of something." His eyes drifted down to her ass as he followed her up the stairs before Amelia answered the eagle's riddle before walking him into the tower without anyone paying much interest to them. Ravenclaws usually kept to themselves in Sirius's opinion, giving them little more than a look before they reached her room just as Alice left it with a knowing shake of her head.

"You are lucky I already had plans with Frank," she said as she walked past Amelia.

"You practically live in his room, Alice. I'm failing to see the difference," Amelia teased before closing and locking the door. She turned and looked back at him. "Now…the shirt you ruined had five buttons…I feel like five is a good number for penance."

"Bones, if you want five, you better take off that shirt of it's getting destroyed too."

Amelia feigned a sigh, reaching up to loosen her tie. "Making me do all of the work does not help your case…" Her fingers threaded through the buttons before slipping the shirt off and unzipping the side of her skirt so it would fall to the ground with her shirt and her knickers. With a flick of her fingers, she released the bra and let it slip down her eyes, eating up the way he was watching her.

"You said I owed you five?" he asked, stepping forward and sliding his hand between her thighs, following one up until he could brush against her.

She gasped, tilting her head back slightly. "Five is a fair number…a bargain even considering you aren't exactly suffering to pay off your debts." Her arms curled around his shoulder to hold herself up as he added pressure and started teasing. Her tongue darted out to wet her lips before biting down her bottom lip as he slipped a finger inside her. She could handle a great deal of stress when she was required to – she couldn't exactly collapse in a utility closet so holding herself up was a must – but this was the privacy of her bedroom and as much as she hated admitting it, Sirius was a worthy adversary. He moved his thumb over her clit like that was his purpose, making her gasp into his shoulder, holding onto him tighter until she was panting and clenching around him.

"One down…" he whispered to her and she hated herself for shivering at it. "Which bed is yours, or one you don't mind ruining," he added with a smirk.

"Far-right."

He moved them over to it, guiding them over before he pulled her down on top of him, sliding a pillow under his head.

"Merlin, you are lazy," Amelia scolded before he pulled her closer.

"Not there," he smirked, sliding her closer to him and angling so she'd straddle his head.

"Okay, I'll give you that…" she squeaked out, her hands wrapping around the headboard as she felt his tongue moving over her. She gripped it as his breath fanned over the sensitive skin, tracing over the nerves and making her whimper for him as he gripped her ass and pulled her closer.

"You hate giving me credit," he sighed into her skin.

"I don't mind giving credit…it's just rarely earned," she breathed out.

"Challenge accepted, Bones," Sirius growled.

"That wasn't – Oh god," Amelia hissed, her body tightening as he rolled his tongue against her. Her head tilted, hair dancing over her back as he gripped her hips and manipulated them against his tongue, whimpering when he began to hum. Her fingers dipped down, burying in his hair. "Black, don't stop," she gasped as she grew closer and closer to a finish. She trembled as he hummed against her, moving with precision until she was gasping for him and struggling to keep her hips steady.

"There's two," Sirius said with a smirk.

"Uh-huh," Amelia sighed softly, taking a beat before adding. "Maybe we should get off Skeeter's bed before she comes back from tutoring," she told him with a sly smirk.

"Where is yours then?" he asked with a laugh.

"Next on," she said before adding, "You said to pick one I didn't mind ruining. I'd never do that to Hestia or Alice, but I think someone should shag in Rita's bed occasionally, don't you? It certainly isn't going to be her."

"Very considerate."

"I aim to please the masses. Being a public figure involves sacrifices. Plus, after the scathing piece she wrote about my father for the school paper, I deserve the satisfaction of knowing I'm the only one who's ever had sex on her bed," she told him as she stood up. "I think we might need a change of venue though," she smirked, slipping a robe on. "Perfect time of day for an empty bath?"

He smirked at her, "You're mad, I respect it, Bones," he said before walking with her to the Prefect bath and letting her deal with the password. "Out," he told a fair of fifth-year Slytherin prefects before locking the door and turning just in time to see her pull the tie on the robe and slip into the water.

"It helps if you are naked, Black," she teased him.

Sirius stripped before stepping into the water. He moved down and gripped her ass, pulling her forward into him. "Satisfied."

"Not yet," Amelia said, sliding her arms around him and pulling him down into a kiss. She sighed as he moved to the edge of the tub, pressing her back against the wall and pinning her there. Her legs slipped around his waist, gripping him tighter as she deepened the kiss. She gasped as he rearranged them, slipping into her and sliding deeper as he moved his lips from hers to begin descending her neck. "God," she breathed out as she rolled her hips to his, feeling every inch of him as he rocked his hips to hers.

Sirius liked to keep her on her toes. Some girls had to warn first or ease into it. Not Amelia. She didn't like predictability and it was one of the things he appreciates most about her. That and her endless sex drive.

When she gasped, he smirked against her skin. He didn't he pull out at first, he just grounded into her g-spot enjoying her reaction. Once her fingernails scratched his skin he pulled out and thrust back into her, starting an erratic speed that forced him to hold onto her as tightly as possible. He was going to get two orgasms out of her before he got one, he was determined and with women, he tended to get what he wanted.

Amelia whimpered, allowing him to pin her hips against the bath wall if he continued to do exactly what he was doing now. There was nowhere for her to go, no way for her to get more from him, but that didn't stop her from trying as he ground into her. She was already close to his previous endeavors, but when he began to thrust, her hips struggled against his grip greatly. His movements were too inconsistent for her to match and it was enough to drive her crazy. Her walls tightened around him as her third finish moved over her.

"I want another one," He growled as she came down from her orgasm. "I want one more and I'm going to get it, Bones," Sirius informed her. He was close, but she was going to cum with him. Sirius lifted her and rested her on the edge of the tub, he edged her forward, putting a hand down on her waist, he spread her legs shifting up inside of her and hitting exactly where her g-spot was until her breathing was erratic and thin. He moved until her back arched against the tile, until she was moaning shamelessly for him, getting everything she could from him. He rewarded it, pressing against her waist and changing up the angle until he got the response he needed.

"Fuc-k," she groaned, her hands moved to grip his forearms as he continued to thrust. Her body straightened and tightened, gasping the word out as she gasped for air. Her hips nested to his as he pulled her in close and she lost it entirely. She shook as she finished, subsiding to a tremble as she began to come down from her high, a rare moment of silence from her.

Sirius didn't pull out of her for a minute or two. He'd bothered her about his shirt a good hour before and spent every moment since touching her in one way or another. His head rested against her for a beat before he lowered out of her, moved to the side to lean on the ledge. "Bones..." He breathed heavily. "I'm going to need an I.O.U for that last one."

"Uh-huh," Amelia said out of breath as she sunk to the seat, up to her neck in the water. She leaned back against the edge. "Oh yeah. That's fine," she said, closing her eyes as she leaned her head back against the edge.
