Struggling to catch is breath, Scorpius dropped his head into the hollow of Rose's neck, their bodies still connected. Below him, her chest heaved as she sucked in air. Scorpius blinked his eyes closed a few times, waiting for sanity, or for some semblance of a thought to float through his head.

He was blank. His head simply hung next to her shoulder, blissfully unaware of anything except the warm girl beneath him.

Slowly, Rose unwrapped her legs from around his waist and he heard her hiss.

His brain snapped back into full functionality immediately and he scrambled off of her.

"Shit, Rose, I'm sorry," he apologized, pushing himself up and bringing her to a seat on the tile. "I'm just grinding you into the tile, here."

His concern dissipated a bit as her head lolled back and she smiled dreamily.

"Grind me into the tile all you want, Scor," she sighed. He laughed into her hair after she drooped forward to lay her head on his shoulder. "The tile, the walls, the floor – Hell grind me wherever you want, that was amazing."

"Agreed," Scorpius ran a hand down her back and urged her into the still-steaming water. "But we need to clean up, dirty girl. Dinner's over soon." His teeth dragged along the shell of her ear before he shoved her closer to the water. She practically purred when she slid in, and he had to shake his head to clear it. Towels. He thought. We need towels.

He returned from the huge linen closets to find Rose floating peacefully on her back in the middle of the pool. He grabbed a small washcloth from his stack of white, cotton towels, and waded into the water to join her.

"You look dead," he told her, reaching down to tug her hand up until she was standing. She pouted at him slightly, wrapping an arm around his neck.

"You never let me have any fun post-coital," she whined, pitching her voice purposefully high. He just shook his head and continued to drag the washcloth across her body, rinsing off sweat and vanilla bubbles.

"If your idea of fun is floating around like a corpse in the Prefect's Bath while I go eat dinner, you're more than welcome to have at it," he told her. She frowned at him and pressed her body closer into his. Despite the fact that he'd just been pressed against her more intimately mere moments ago, he enjoyed the feel of her warm skin against his.

"Dinner without me?" Rose took the washcloth from him and dipped it in the water before running it over his back and shoulders. "You wouldn't dare."

"Oh, Rose, I think we both know that I'm plenty daring when I need to be. I'm going to be an auror, for Merlin's sake."

"Mmm, you bravely stood up to Al while you were buck-naked and mid-handjob-"

"You will never, ever, under any circumstances understand how hard it was for me to pay attention to him while you were right there."

Rose chuckled and held the washcloth up for him to take again. "Done."

Scorpius put an exaggerated, thoughtful expression on his face.

"Are you sure? You may have missed some spots…" He trailed off, sweeping his hands down his body to cup his testicals. "Oh, Merlin, I may have missed some spots…"

Rose's giggle filled the warm bathroom as his hands swept over her breasts several times. She batted him away and made her way out of the tub to where her clothes were tucked away across the room.

"'Missed some spots'," she scoffed. "Not if it makes me miss dinner. This is one of the last times we'll get to eat Hogwarts roast. Are you really going to try and grope me into missing roast?"

She looked at him pointedly while toweling off. He grinned at her from where he was floating in the water.

"I'd never attempt it. I'm not that daring," he said.

"Ha! Good man. Your instincts for self-preservation are remarkable." She began to pull her clothes on one item at a time. He growled softly when she shimmied her skirt up over her hips.

"I'm going to miss you in these uniforms, Rosie," he told her, righting himself and wading to stand at the edge of the pool closest to her. "It just does fantastic things for you legs."

Rose twisted her hair up into a bun atop her head and took a few steps to the edge of the pool, squatting down in front of him so their faces were almost at the same height.

"My legs aren't good enough on their own? How rude," she scolded him, reaching out to tweak his nose.

"Shut it, you know you're bloody gorgeous," Scorpius swatted her hand away from his face and she laughed again.

"Well, thanks anyway for the reminder. It's much appreciated."

"Any time," his face grew suddenly serious. "Rosie, we never talked about…this. About-"

"What we're going to do when we graduate?" She finished for him, nodding. They stared at each other for a moment, each desperately wondering what the other was thinking. Rose broke their eye contact to peer across the room at the mermaid window.

"I suppose… we should… keep… keep going, don't you think?" Her brow furrowed. "I know we said it's only till we get it out of our systems-"

"You're not out of my system, yet."

She kept her gaze at the mermaid, but shivered at the forcefulness of his statement. She nodded, still not looking at him.

"That's good. Me either. That is… You're not…I'm not ready to…" She swung her gaze to meet his, trying to ignore her suddenly burning ears. Stupid trait to inherit from my stupid family. "Well, it's not like we can stop any time soon. I've just promised you twelve blowjobs and I'm not one to re-nig on promises."

He cracked a half-smile at her matter-of-fact tone, feeling suddenly lighter than he had in weeks now that they'd both agreed to continue with their little relationship.

"No, of course," he agreed. "We can't have it getting around that you're not following through with your promises of oral sex. What ever would that do for your reputation, Rosie?!"

She nodded firmly. "Indeed. I'm glad we're on the same page here." She stood to walk out of the room, but Scorpius called out behind her.

"So, I guess we'll just check back in a week or so when you've settled up on those blowjobs."

Rose turned slowly on her heel to look back at him.

"You think you're going to go through twelve blowjobs in a week?"

He shrugged nonchalantly, leaning once more against the side of the pool. "If I offered you a dozen rounds of oral sex, wouldn't you want to use them. Quickly?"

"We're not talking about me… Wait, what about me?"

"What about you?"

Rose glared at him. "Well, while you're getting one point seven blowjobs a day-"

"Let's spread it out to one or two a day alternating until we're through. I don't like to bring fractions into my orgasms," he drawled.

She put her hands on her hips and fought the smile that was rising on her face.

"Fine. One or two a day alternating. What will be happening with me? Who's going to me looking after my orgasms?"

"Rose, you offered me twelve blowjobs out of the kindness of your heart. I can't be held responsible for your sex life when mine is taken care of. I'm just not that selfless," he shrugged, grinning at her and winking.

Her lips twitched up into an even deeper smile.

"We'll discuss this at dinner," Rose turned again to the door.

"You can't put stipulations on IOU blowjobs, Rosie," he called after her. "It's bad form."

"Watch me," she had almost reached the door to the hall.

"I'd like to take my first IOU tomorrow morning, for the record. That sounds like a fantastic way to wake up…"

Scorpius trailed off as she opened the door, and snickered when she flashed him her middle finger before pulling it closed behind her.

He sighed and jumped out of the pool, padding to where she'd left him a dry towel, and smiliing when he found she'd put a warming charm on it for him. Despite an unfortunate run-in with Al, his day was looking up. He had roast for dinner, he had Rose in his bed for a while longer (As long as she'll let you stick around, you lucky bastard, he thought to himself), and he had twelve blowjobs to look forward to. Scorpius had a grin on his face for the rest of the night.

And was still grinning when he woke up the next day to Rose in his bed in his head boy rooms, kissing her way down his torso.

"This is one," she informed him, licking her lips as she eased his flannel pants down his legs. "Eleven more to go…"

Scorpius settled back into his pillow and threaded his fingers through her hair, trying to think of an excuse to get her into the Prefects Bath again today.
