Wasn't planning on making this a multi-chapter but… well, here we are. Onward.

About 10 minutes earlier…

"We've got to stop meeting like this."

Rose's dark brown eyes snapped open at the sound of Scorpius's voice, and she turned her head to peer around her shoulder.

There he was, lounging lazily against the bench by the door. He'd discarded his robes and he looked like some sort of Prince or God, sitting back with his tie askew and his sleeves rolled up to his elbows.

"Meeting?" She asked sweetly, turning back around to grin at the stained glass mermaid in front of her, who gave her a saucy wink in return. "Seems to me like you're the one interrupting my bath. I'm not meeting anyone. I'm innocently bathing."

She dipped her pink loofah into the vanilla scented bubbles and brought it to her skin.

"Mmm, innocent," Scorpius rumbled across the room behind her, sarcasm dripping from every syllable. "And I suppose that you wanted to be left completely alone after you casually dropped into conversation that your only regret is that you never had sex in the prefect's bath. I'm not buying that, Rosie. Not for one minute."

She looked back over her shoulder and narrowed her eyes at him.

"I merely said-"

"Oh, I heard very well what you said. It's been repeating in my brain since you said it yesterday." He interrupted her, his voice taking on a sickly sweet falsetto: "'I suppose I always wanted to have a nice shag in the prefect's bath. Ah, well…'"

Her eyes narrowed even further and she turned her back to him once more. She ran her loofah slowly up her torso to circle her breasts, letting out a breathy moan.

"Do NOT play your little sex games with me, Rose Weasley," he accused, making her flinch and smile at the same time. "I learned to read past those years ago. They don't work on me anymore."

Rose tilted her head to the side, bringing the sponge up to her neck.

"I find that highly interesting, since we've been only been having sex for the last few months."

She heard a noise behind her and raised one eyebrow. The noise stopped. She resumed her slow movements.

"Besides, we both know my sex games will continue to work on you until the end of bloody time," she said lightly, dipping the loofah back in the water the run over her breasts, again. Really, she was going to rub them raw at this rate. Why wasn't he in the water yet?

"Not true." He sounded a little defensive, and she said as much.

"I am not being defensive," he said, defensively. "I'm just saying you couldn't have been any more bloody obvious, saying that in front of Albus. You might as well have hired a singing telegram to chase me around the halls, begging me to shag you in the prefect's bath."

He picked at a fingernail, trying to adopt an air of indifference. His eyes flicked up to where she stood, rising out of the water like Venus. Her long, red hair hung in wet curls around her back, falling gracefully past her delicate ribcage, ending just above where her hips flared out into what Scorpius could personally attest was a world-class ass. He just couldn't see it right now. And he really, really wanted to.

"Oh, please," Rose scoffed from the water. Scorpius peered at the stained glass in front of her, desperately hoping to catch a glimpse of her reflection. It had been weeks since he'd last seen her tits… Ok, well…Almost six days. Still.

"We've been at this for almost seven months," she continued, still running that damn loofah over her body. "If he was going to figure it out, he would have by now."

Scorpius had to agree with that. It seemed that despite his high marks in class, Albus was completely blinded to the fact that his two best friends were taking every opportunity possible to shag like rabbits. The thought brought up some unpleasantly guilty feelings for both of them. They hadn't meant to start up a torrid affair in the middle of their last year at Hogwarts. The one-time, completely by accident, never to be repeated again sex had just… continued to… repeat. And they had both decided that it was probably for the best that Al not know.

"Just until we get it out of our systems," Rose had muttered breathlessly one night atop the astrology tower. Scorpius nodded enthusiastically.

"It's a complete fluke…." He gulped as she reached for his belt buckle.

"Absolutely," she'd said, her breath leaving her body in a rush when he pushed her damp panties roughly aside. "Not going anywhere… just sex…" She bit off a moan.

"Mmhmm," Scorpius dropped to his knees on the cold stone, burying his face between her thighs.

They hadn't discussed the matter since then.

Scorpius knew that while Al might be able to sanction his two friends being in a relationship, he'd never understand the no-strings-attached sex arrangement they had going on. Because it was the perfect, innocent, "scratch my back, I'll scratch yours," "my, what a horribly stressful exam, I need to blow off some steam," sort of arrangement. One that didn't affect their friendship at all…

At all. Scorpius reminded himself firmly. He loved Rose. He'd always loved Rose… the same way he loved Al or any of his friends he'd made at Hogwarts. Right?

"Scorpius."

He lifted his head to look at her and… she had turned around.

His thoughts flew out of his mind as his gaze dropped down her body, taking in her warm eyes, slender nose, graceful neck, pert breasts, tight stomach… Fuck, she's gorgeous.

He quirked a brow at her.

"Yes, Rose?"

"Do I have to resort to hiring a singing telegram to beg you to come shag me in the prefect's bath?"

His mouth twisted into a half-smile and he smirked at her.

"No begging necessary, love."

Rose watched as he shed his clothes, working at a leisurely pace on buttons, zippers and shoelaces, until his was walking to her completely naked. And what a sight to behold. She'd seen him naked dozens of times, now, but… Oh, my. He never failed to disappoint.

Years of Quidditch, along with what he assured her haughtily was the "natural Greengrass metabolism," had sculpted his body into a work of art. She watched his thighs bunch and his abs ripple as he hopped smoothly into the bath, wading to where she was in the middle of the water.

His grey eyes were stormy as he made his way to her, and her skin broke out in gooseflesh when he reached out to grip her hips and draw her to him.

"We're going to be caught for sure," he murmured, sliding his hands up her arms to cup her face. "We're both going to come out of here smelling like a cupcake shop."

"You don't like vanilla? Not manly enough for you?" Her voice sounded breathy, even to her own ears, as he speared his fingers through her thick hair, running his hand through the red strands.

"I love vanilla," he said. He dipped his head down to run his nose over the top of her head before he tipped it back to look at him. His eyes met hers. "Vanilla reminds me of you."

He saw her lips tilt into a smile at his declaration and bent to meet her. Their mouths brushed softly and he pressed into her almost chastely. He enjoyed the simple kiss more than he should have, and felt his heart thud in his chest despite the fact that this was one of perhaps hundreds of kisses they'd shared over the past seven months.

His heart beat harder when her tongue flicked out to run over his bottom lip. He groaned and pulled her closer, running his hands down to her bum to rock her up against him. She was so soft and he… well he was not soft at all, at the moment.

The couple stood there in the warm water, wrapped up in the kiss, hands exploring planes and angles that had all been discovered before. Rose gasped in a breath and gripped his short, blonde hair in her fingers when his mouth worked its way down her neck.

"You said you wouldn't make me beg," she accused, groaning when he ran his tongue over the tip of her breast. She groaned again in frustration when he pulled away.

"No begging," he assured, peering down at her. "Be patient. There's no way you're ready already."

"Bet me," she growled, hopping up to wrap both legs around him. He wrapped his arm under her to steady her, but she was buoyant in the water.

He raised his eyebrow at her again. Rose bit her lip when she felt his hand travelling down her stomach and reaching between her thighs. Scorpius raised both eyebrows when he found her slick and wet with desire.

Wasting no time, he turned and waded through the water to the wall, spinning to sit on the built-in ledge and arranging Rose to straddle his lap.

"Rosie, you're wet," he whispered it into her arched neck as his fingers continued to play with her.

"Yes, I'm in a bath, you moron."

"That wasn't nice."

"Well, you're being an idiot. An idiot who still isn't inside meee…" Rose gasped when he used two fingers to spear into her suddenly.

"You know what I meant," he told her, watching with hooded eyes when she began to move her hips in time with his fingers. He slowed his pace and pulled out almost painfully slowly, her hands clenched at his shoulders.

"Mm… ah…"

She tipped her hips forward, trying to force him back in and speaking in incoherent syllables. He pulled his fingers back again, using his thumb to circle her clit, driving her even further into madness.

"Usually, I'd make you pay for your cheek," he warned her, pinching her bottom underwater and enjoying her little squeal of surprise. "But, Rose..." He groaned as he pumped his fingers into her again. "Baby, you're so wet for me."

She threw her head back and cried out softly, moving her hips with the steady rhythm he created.

"That deserves a reward, don't you think?" He panted. Rose's weightlessness in the water allowed her to move freely on his hand and - he didn't know how it was physically possible - but his cock got even harder watching her breasts bounce with their motion.

"Yes… Scorpius… Oh, yes…"

She was the sexiest thing he'd ever seen. Scorpius bit off a moan when she reached up to cup her breast, rising and falling on his two fingers. She sighed in pleasure when he added a third. She nearly screamed when he crooked his fingers and hit the spot that made her go wild.

Her hips drove wildly in their own rhythm, now. She had no control as they snapped and wriggled, seeking release.

"Scor… please! Oh… oh please, Scorpius…"

"I told you, love, no need to beg."

His voice was gravelly as he wrapped his other arm around her, gripping her body closer to feel her breasts press against his chest, her hands in his hair. She was close, so very close. He could feel her tightening around his hand. He growled in satisfaction, knowing that she was seconds away from-

"Scor, are you in here?!"

Scorpius launched to his feet in panic, hearing Albus's voice cut through the thick fog of lust that was his brain. Rose's eyes snapped open and she yelped in surprise, suddenly finding herself dangling in midair, held only by one of Scorpius's strong arms.

"I'm coming in anyway so cover your pasty arse up," Al announced and the hinges on the thick wooden door began to squeak open.

Scorpius spun around to face the door and Rose barely had a chance to gulp in air before he unceremoniously dropped her into the pool.
