Author's Note: Okay, here's the next chapter. Again, there is plenty of smut in this one, which is why it's taken me a little longer to write. I'm just not that comfortable with it yet. Hopefully I'll get used to it soon.

By the way, thank you to the 2 reviewers who caught my mistake in the last chapter. Little slips like that drive me nuts and I guess I missed it in my rush to post something for you guys. I always proofread my work but I must not have been paying close enough attention. I really appreciate the careful reading!

A guest reviewer also mentioned that it would be impossible for Scorpius to call Rose by flower names for 6 years and not repeat some of them. They also said that it could be fun to have him repeat certain flowers. This is exactly what I am planning on happening. He will start repeating some of them as their relationship develops, depending on his mood but, for the moment, I want them all to be different. I am sure he had used some of these numerous times but I think it's more fun for me to use as many different names as possible. If you want to catch all of the repeats later on, I would suggest going back and reminding yourself of the flowers he uses during their most important moments. Thank you for your observations, Arcoiris. I'm sure that there are many other readers who have been wondering the same thing. I hope everyone is enjoying the flowers as much as I am!

As always, thank you so much for reading! I really appreciate it! I hope you enjoy, and please let me know what you think.

Chapter 9: Addiction

The next two and a half weeks passed quickly for Rose and Scorpius. After their encounter on top of the Astronomy Tower, both had finally resigned themselves to the fact that they wanted one another. Badly. They couldn't seem to keep their hands off of each other. This didn't mean that they had suddenly started getting along, quite the opposite in fact. The sexual tension had just painted itself—in a very thick coat—over the already constantly simmering rivalry between the two.

Now, every time they shot a glare in the other's direction, or sent an insult flying across the room, they couldn't help but associate the increase in friction with the way they had been taking that conflict out on one another as of late. Arguing had become a prelude to sex in their minds and they were having a hard time ignoring the ever-present lust that seemed to haunt them whenever they were in close proximity.

The one thing that they were both sure had not changed, however, was that they hated each other. This whole shagging each other's brains out in broom closets and abandoned classrooms thing was just another aspect to their hostile relationship. Besides, they could both do with a way to relieve some stress now that they were in their NEWT year.

Sneaking off to closets and classrooms became an almost daily occurrence. Scorpius would frequently pass Rose a note telling her to meet him on top of the Astronomy Tower, or someplace on the grounds, and she would reciprocate with her own inventive hiding places. Thanks to the Marauder's Map, which Rose had slipped from Albus's trunk one evening while he was out on a date, there was no shortage of rendezvous spots. She didn't think that her cousin had noticed the map missing yet, but she knew that she would have to be careful to keep him from finding out that she was the one who had taken it. It would raise far too many questions that she was not prepared to answer.

Scorpius was very quickly becoming addicted to the way that being with Rose made him feel. Everything seemed to slip away when he was inside her. He just couldn't seem to get enough of that feeling. Obviously, she felt the same way. Her body was so responsive to his every touch and Scorpius found that he was beginning to become reliant upon their stolen moments in abandoned parts of the castle. She still pissed him off more frequently and more intensely than anyone he had ever known, but she was one hell of a good shag. He was going to enjoy it for as long as it lasted.

One afternoon in Defense Against the Dark Arts, Rose found herself a bit distracted. She was supposed to be focusing on dueling with Nathaniel Wood but her concentration kept slipping. Scorpius was on the other side of the room, practicing counter-jinxes with his partner, Oliver Swott, and with him in her sightline, Rose just couldn't seem to keep all of her attention on what she was supposed to be doing. The fact that Scorpius's gaze was also sliding to hers on a regular basis was definitely not helping.

A flash of light ripped Rose's focus back to the duel she was taking part in and she barely managed to slice her wand through the air and repel the nonverbal spell that Nathaniel had sent her way. The spell bounced off of her shield and went careening off across the room, straight at Scorpius. Rose gasped as he was knocked off of his feet and slammed into the row of desks behind him.

As he slowly got to his feet, shaking his head in an attempt to fight the dizziness, Scorpius turned his furious gaze upon Rose. His eyes sparked with rage and the muscles in his jaw were clenched. He was definitely angry.

The entire class fell silent as Scorpius began his menacing prowl across the classroom towards the redhead who was now standing with her feet apart and shoulders squared in preparation for whatever attack he might mount in retaliation. Professor Fenwick looked as if he wanted to hurry forward and put a stop to whatever was about to take place, but the look on Scorpius's face seemed to give even him pause.

"What the hell was that for, Aster?" Scorpius snarled.

"Believe it or not, Malfoy, that one was actually an accident. I was distracted." Rose answered honestly, her tone casual but her words communicating to the looming blonde in front of her just what had been distracting her.

Recognition flickered across Scorpius's icy grey eyes before he narrowed them again. "You might want to be more careful when it comes to these little accidents of yours. One of these days you may not survive the consequences."

Rose's eyes flashed and Scorpius felt his stomach clench with desire in response. There was nothing more magnificent than Rose Weasley when he got her fired up.

"Was that a threat, Malfoy?" she growled.

"Oh, I don't make threats, Hellebore. You should know that by now." Scorpius had moved closer during their argument so that he currently towered over her. Their gazes were locked and their breathing was harsh. Rose could feel the gusts of his warm breath brushing over her face as he leaned in close. They both felt a surge of hunger for something that would definitely not be appropriate in this particular setting.

Rose and Scorpius both sensed the shift in the tension between them and immediately began reeling themselves in. Clearing her throat, Rose attempted to redirect the argument, pulling them away from more dangerous territory.

"Hellebore? What do you do, sit alone in your room at night with an encyclopedia of botany, looking up names of flowers that you can call me? Isn't that just a little pathetic, Malfoy?"

Scorpius changed gears, quickly and easily following her lead. "Hey, there's nothing wrong with being informed, especially since I'm taking Herbology. And it is so worth it to see just how quickly I can piss you off. You need to get some thicker skin there, Heliotrope."

Rose opened her mouth to respond but it seemed that Professor Fenwick had managed to find his voice. "I think it would be best if we ended today's lesson a little early. Miss Weasley, Mr. Malfoy, if you would please step away from one another and go on with your days?"

Both students' heads snapped in the direction of their professor and he gulped at the intensity of their gazes. When they turned away from each other and began to gather their things, Fenwick let out a sigh of relief. Rose couldn't help but think that, for a Defense Against the Dark Arts Professor, he was really quite timid. Granted, she and Scorpius intimidated some of the more stalwart teachers at the school, but still. If you were too afraid to break up what hadn't even been one of their more heated confrontations, you probably shouldn't be teaching students how to survive an attack from a dark wizard.

Out of the corner of her eye, Rose saw Scorpius looking her way. She could still feel the desire for him simmering in her veins and the barely controlled heat of his expression caused her breath to hitch in her throat. He held her gaze for an instant more before turning and walking out of the classroom.

Rose took a deep breath. She knew what that expression meant. He wanted her and he wasn't going to be satisfied until he had her. For that matter, she probably wasn't going to be able to think about anything else but him for the rest of the day if she couldn't let off some of this pressure. Glancing around her, Rose slipped out of the room and headed in the direction that Scorpius had gone a few moments earlier.

When she rounded the corner, a hand shot out and grabbed ahold of Rose's wrist, dragging her into a broom closet. Familiar by now with the logistics of these particular cramped spaces, Rose maneuvered her body against the wall while simultaneously pressing herself closer to Scorpius.

His mouth was on hers before she had a chance to speak, punishing her lips with the intensity of his kisses. She gasped as his hands shoved her robes to the floor and pulled her shirt open with such force that he sent a few buttons scattering.

"Scor!" she scolded before moaning as his mouth descended to envelop the flesh of her breast.

"Merlin, Rose. I am so turned on right now," he murmured as he licked his way across her flesh. She whimpered as he bit down on her nipple, her desperation rising.

She needed to get to skin. She tore at his clothing, pushing it out of her way so that she could run her hands over the taut planes of his back. He groaned as he felt the prick of her nails, the pain adding just another layer to the intensity of the moment.

Scorpius plunged his hands under Rose's skirt, tearing her panties away and sliding his fingers into her warmth. She threw her head back, barely noticing as it banged into the wall behind her because now his lips were on her throat and his fingers were doing something amazing inside of her, their movements sending ripples of pleasure throughout her entire body.

She regained enough sense to tug at his belt, freeing him and firmly stroking her hand up and down his rigid length. It was Scorpius's turn to be overwhelmed with pleasure and, for a second, he was sure that his knees would give out. But then, she was guiding him between her spread thighs, lining him up with her opening, and he was sinking into her slick heat.

When she had managed to regain the ability to speak, Rose turned to Scorpius. His face was still flushed from their coupling, his hair was a mess, and he was looking at her with a satisfied smirk turning up the corners of his kiss-swollen lips. If she didn't feel just as smug and satisfied as he looked, she would have hated him for it.

She took a deep breath. "If this is going to keep happening, I think we need to give ourselves some guidelines. Or at least try and define exactly what it is that we're doing."

"Okay. What did you have in mind?" he asked, a wary expression on his face.

"This is just sex. We don't like each other. We're not friends, so we can't even be 'friends with benefits.' Just sex. Got it?"

"Absolutely. No attachments, no emotions. Just sex."

"Good."

"And no one can know about this."

"Oh, God no. We can't let anyone find out. That would be disastrous."

"Glad we're on the same page."

Scorpius's eyes drifted down to focus on Rose's mouth. Despite the fact that he had been completely sated mere minutes ago, he could already feel himself beginning to harden again.

"Rose," he whispered, lowering his face to hers and pressing their foreheads together as his breathing began to get heavier.

"Why is it you only call me Rose when you're inside me, or about to be?"

"Because my brain loses almost all ability to function when I'm inside you, or about to be."

"Good enough for me." Rose tipped her head back, connecting their mouths as she grabbed onto Scorpius's hair to bring him closer.

"Just sex," he murmured into her mouth.

She nodded before hitching herself up, wrapping her legs around his waist, and impaling herself on his hard length. She let out a satisfied groan. "Just sex."

A few days later, Rose and Scorpius met on the seventh floor at half past eleven. They hadn't managed to find the time to be together since they had laid down the rules about the nature of their relationship and both felt their bodies humming with anticipation as soon as they saw each other.

"Where are we going?" Rose asked once she reached him.

"I'm not sure. I was thinking the Astronomy Tower but the temperature dropped way too much to be comfortable up there."

Rose nodded. "Well, come on. Let's just find an empty room or something." She turned on her heel and made her way down the corridor.

At the first door they reached, Rose pulled Scorpius inside, immediately finding his mouth with hers and wrapping herself around him. It had been far too long since they had last done this. She felt like she was going to explode.

Scorpius's hands were under her shirt and hers were working on his belt when they heard a noise.

"I'll take the rooms on this end of the hallway, you take that end," a distant voice called out.

Rose pulled back, looking at Scorpius with wide eyes. "Prefects," she hissed. She reached into her robes and pulled out the Marauder's Map. "It's Anita Summers," Rose told him when she identified the dot rapidly moving towards their hiding place. "We can't let her see us. She's a notorious gossip."

Scorpius nodded, turning his head to look down at the map. "We've gotta move." He grabbed Rose's wrist and hauled her out the door.

They raced down the corridor as quietly as possible, glancing down at the map every so often to check the prefects' positions. Suddenly, another dot appeared and started heading towards them from the opposite direction of Anita.

"Fuck!" Scorpius snarled. "This is not good." He screeched to a stop, halting Rose with him. He frantically took in their surroundings but there was nothing there besides an old tapestry of an idiotic wizard teaching trolls ballet. They were trapped.

Rose wanted to scream in frustration. She plunged her fingers into her hair and began pacing back and forth in agitation. "We can't let this get out. Maybe if we pretend that we're fighting?"

Scorpius looked her up and down, taking note of the hickey forming on her throat and her well-kissed appearance. "You don't look like you've been fighting."

She shot him a look of disdain. "We need somewhere to hide. We need…" She trailed off as a pair of doors materialized in the wall behind her.

Scorpius looked at her in astonishment before grabbing onto her arm and pulling her through the doors, closing them inside.

They stood in darkness for a moment before the room became illuminated by torches mounted on the walls. It wasn't a very large space, but it was clearly out of place in a corridor filled with classrooms. Directly in front of them was an enormous canopy bed, its sheer drapes falling around an intricately carved wooden frame and enclosing what appeared to be a luxurious feather bed.

"What is this place?" Scorpius asked, turning around in a slow circle to take in all of the sumptuous furnishings that were lining the elegant bedroom.

"It must be the Room of Requirement. My parents told me about this place. It becomes exactly what you need it to be, whenever you need it." Rose looked around in wonder.

"Can we be found in here?" he asked, nervously looking back at the doors behind him.

Rose shook her head. "Not unless whoever is looking for us knows exactly what we asked to find this place. The adults in my family always refused to tell any of us where it was located. Probably so that we wouldn't be tempted to use it for inappropriate things."

"You mean like what we're about to do?"

Rose grinned. "Exactly."

Later, as they lay among the tangled silk sheets, Scorpius noticed a large burn mark in the corner of the room. It was partially concealed by the wall hangings but was still quite apparent. "I wonder what happened there?"

Rose turned her head to examine the area he was pointing out. Now that she was looking more carefully, she could see that there were several areas in the room that looked a little worse for the wear. "It must be from the Fiendfyre. During the Battle of Hogwarts. My parents and Uncle Harry were in here. So was your father, actually. And Goyle's father, and Crabbe—another Slytherin. Crabbe tried to kill Harry and my parents with cursed fire but he couldn't control it and it killed him. My dad always wondered if the Room survived. I guess now we have proof it did."

Scorpius was now looking at her with cautious interest. "How did the rest of them get out?"

"My dad and Uncle Harry grabbed broomsticks and saved your dad and Goyle. It's one of the few stories about that battle they're actually willing to tell." She told him, averting her eyes and concentrating on running her fingers up and down his arm.

"Do you know what my dad was doing in there in the first place?" Scorpius asked, his voice making it clear that he wasn't sure that he wanted to hear her response.

Rose merely nodded, the answer evident in her expression. Scorpius closed his eyes, too ashamed of his family's past to hold her gaze.

"Hey," Rose whispered, sitting up so that she could see his face better. "It's not your fault, you know." She gently ran her thumbs across his eyebrows, smoothing away the frown lines that had etched themselves there.

Scorpius looked up at her, unmistakable sorrow in his smoky grey eyes. With a reassuring smile, Rose leaned down, capturing his lips with hers and sinking into his warmth. He ran his hands gently down her sides as she hovered above him, causing her to sigh into his mouth.

She pulled back, stroking her hands over him, and pressing gentle kisses to his cheek, his jaw, his throat and, finally, right above his heart. Scorpius whimpered, diving his fingers into her hair and caressing her scalp as she moved lower, scraping her teeth over his abdomen.

Rose looked up to see that Scorpius had his eyes closed. His breathing had become labored and she smiled at the fact that she had been able to take his mind off of the pain he had been feeling moments ago. She returned her mouth to his skin, slowly sliding up his body until she could straddle him.

His body bowed back as she sank down onto him and his hands glided down her body, over her breasts and stomach, to settle on her hips. He began to gently guide her motions as she rode him, setting a slow and steady pace. Scorpius looked up at her as she undulated against him. Her wild scarlet curls were haloing her head, the light from the flickering torches filtering through the silky strands and framing her face in a soft red glow.

He felt himself nearing his peak and slid his hands up the smooth curve of her spine, cupping her neck and pulling her down to him so that he could slide his tongue into her mouth. The soft touches and tender kisses drove them closer and closer to their peaks. They came together, the slow, gradual crescendo culminating in a quiet explosion that melted its way through their bodies before floating them weightlessly back down to earth.

Rose and Scorpius lay side by side, making sure not to touch, their bodies rigid.

"What the hell was that?" Rose demanded in a shaky voice.

"I have no idea."

"We can't do that again." Rose jumped out of the bed, frantically grasping for the articles of her clothing that were scattered across the floor while keeping the large expanse of the bed between them.

"Absolutely not. That was not part of the deal." Scorpius sounded just as stunned as she felt. He too had risen from the bed and was now pulling on his pants, carefully avoiding any eye contact.

"I think this is a sign that we should stop this. It was a bad idea from the start."

"We should just forget about it. We've probably gotten it out of our systems anyway."

"Good point. Now we can just move on." Rose pulled her shirt over her head and quickly swirled her robes around her shoulders.

"Sounds good to me. We can go back to hating each other, the way it should be."

"We never stopped hating each other," she shot back.

"True. Well, Jasmine, it's been fun."

"Prat." She moved to the doorway, pulling it open. Before she stepped through, however, she turned around, looking at Scorpius one last time. "Goodbye, Malfoy."

"Goodbye, Rose," Scorpius responded, catching her gaze with his own. Their eyes locked for a moment before Rose broke the contact, slipped out into the corridor, and was gone.

Uh oh...I guess it wasn't just sex after all! Time for a major Rose/Scorpius freak out. That should be fun to write :)

The next chapter is..."Withdrawal." That one should be up in the next couple of days. I have it about 1/3 of the way done. Hope to see you next time!
