Just a smutty little one-shot I wrote for something on twitter. This is my first time writing this paring, so please be nice? And please make sure you read the TWs!

ooo

"Flowers?" Hermione didn't look up as he sauntered into the room; her head resting against the edge of the bathtub, eyes closed and lips slightly parted.

"Mhmm." she hummed, heaving a sigh that almost…almost raised her chest enough to expose her bare breasts. "Lavender and chamomile. It's supposed to help me relax."

Sirius took a tentative step closer, curiously eyeing the petals floating on the fragrant water. "And what are the cherry blossoms for?" He asked, lowering his hand into the water and running his fingers through the sea of delicate pink flowers.

At that Hermione finally opened her eyes and squinted at him, her lips tilting into a pert little smirk. "Oh those are just for aesthetics. I wanted the water to look pretty."

Sirius hummed thoughtfully. In his opinion any water would look good as long as it had her in it.

"Thanks for letting me use your bathtub by the way." Hermione added, closing her eyes again and sinking a bit deeper into the water. "I really needed this."

"You been having nightmares again?" He asked, studying the way her wet curls stuck to the skin of her exposed throat. Gods she was beautiful. He'd never really noticed it until she'd moved into Grimmauld Place with him and Harry after the war.

She'd seemed so broken, the realisation that her parents' memories were lost for good being too much for her to handle. She was grieving as if they'd died, because for her they had… So she'd refused to eat or sleep, always just sitting there and staring into space. She'd even stopped reading, which was highly unsettling… and the more Sirius had watched her waste away, the more he'd felt the need to take care of her.

At first, he thought it was through some sort of parental affection for her, that he felt like it was his duty to care for her, but then Hermione started to very slowly come back to life, and with every balanced meal he got her to eat, and every little smile he managed to put on her lips his affection for her grew into something much bigger and needier.

He knew that Hermione could feel it too. It was evident in the way she leaned into his touch when he offered to rub her back, or the way her eyes lit up when he walked into the room. He'd even seen her bite her lip whenever he wore those tight leather pants that showed off his toned thighs and perfectly shaped arse.

He knew he'd probably go to hell for it, but he wanted her. Desperately. And he had a feeling that Hermione wanted him just as much.

"Yeah" Hermione nodded, drawing him back to the present. He watched a small crease form between her eyebrows as she sighed. "Almost every night."

She opened her eyes to look at him - warm chestnut-brown surrounded by thick, dark lashes - and his heart clenched painfully at the lost expression in her eyes. Like a scared deer, caught in the headlights.

"I don't know what to do anymore. I've tried everything."

Sirius gave her a warm smile and reached out to swipe a wet curl out of her face. "You sure?" He asked, a jolt of nervous energy coursing through his veins. "You been taking care of yourself, kitten?"

Hermione's eyebrows drew together ever so slightly, her head tilting to the side in a contemplative manner. "Well, yeah." she said, swishing her hands back and forth through the petals floating around her legs. "What do you think this is?"

Sirius huffed out a small laugh, unable to hold it back. "That's nice princess, but it's not what I meant." He raised a suggestive eyebrow at her and jerked his head towards a spot below her belly, hidden away below the depths of the flowery water.

"Oh." Hermione breathed, realising what he was talking about, a light blush sweeping across her cheeks as she shook her head. "Not really. I mean… I haven't been in the mood lately."

Sirius smirked. It was adorable how flustered she got about topics like this.

"Well…" He said, sinking down onto the cold bathroom tiles to be at her eye level. "Maybe you should consider trying it."

He raised a hand and lightly brushed his fingers against her knee, which caused Hermione to gasp. Sirius paused briefly, giving her the time to withdraw, but when she didn't move he carried on, slowly sliding his hand between her knees and down the inside of her thigh.

"You see," he murmured, watching Hermione's big, brown eyes follow the motion of his hand, her bottom lip caught between her teeth as if she was trying to hold back a needy whine. "I'm not saying it will solve all your problems, but it'll definitely take the edge off a little."

He held his breath as he pushed through the surface of the water, his throat feeling very dry all of a sudden, as his fingers moved further down the silky slope of her thigh. He could practically hear her heart thundering in her chest, her breath coming out in a shaky gasp, as she let her legs fall open to allow him better access.

Encouraged by her reaction, Sirius pushed his hand even further into the water until he finally reached her core, tentatively swiping a finger across the soft skin of her folds.

Hermione's reaction was instant, her hips bucking into his touch, as a lewd noise broke from her lips, so hot and needy that it shot straight to Sirius' cock, causing it to stir.

"That's it, kitten." he murmured, trying to ignore his own, rapidly growing desire. "Let me make you feel good."

Gods he wanted her…needed her. But this was not for him. It was for her. To make her feel good and help her relax.

He sucked in a deep breath, determined to finish the task, and began to slowly drag the pad of his thumb across her slit and all the way up her clit. It was clear when he reached the sensitive bud, because Hermione let out a sharp hiss, her mouth falling open as she let her head drop against the edge of the bathtub and arched her back.

Sirius smirked, beginning to draw tight circles around the bundle of nerves, all the while watching Hermione's reactions carefully. Her breath had become short and laboured, the swell of her breast creating tiny ripples in the water as her chest rose and fell, her nipples pink and taut as they peeked out from between the floating blossoms in the water.

Sirius let out a low groan as he watched Hermione's hand reach up to pinch them, desperate to feel them between his lips, to lick and suck them until they were rock hard and tingling with pleasure.

"More!" Hermione whined, pushing her hips up to grind her core against his palm. "Please, Sirius, I need more."

"Shhh." He soothed, ignoring the way his name on her lips made his cock throb in his pants. "Don't worry, baby. I'll take care of you."

He dragged a finger through her slit, gently circling her entrance, before he pushed in, - a slow and deliberate motion that made both of them moan with pleasure.

"Gods you're tight." Sirius rasped, revelling in the way she clenched around his finger, hot and wanting…and so very wet.

Hermione keened, her hands clutching the edge of the tub as she pushed herself further into his touch, almost entirely rising out of the water and exposing herself to him in the process.

Sirius drank her in, tracing the curves of her breasts with hungry eyes, before they travelled further down her body, across the dip of her waist and the soft plane of her belly, all the way to her needy cunt, mesmerised by the way his finger pumped into her, over and over again.

She was the most gorgeous thing he'd ever seen.

Hermione let out a small gasp and squeezed her eyes shut when he added another finger, her mouth falling open with pleasure as she bucked her hips once more.

"Ah, ah, ah! Keep your eyes open." Sirius demanded, overcome by a sudden streak of possessiveness. "I want you to look at me. Want you to watch how I make you come."

Hermione's eyelids fluttered open, her pupils blown and hazy with lust, as her eyes found his and their gazes locked.

"Good girl." He growled, causing Hermione to whimper at his praise. Feeling rather pleased with himself he flashed her a smug grin. He could feel that she was getting close, it was evident in the rapid rise and fall of her chest, in the lewd mewls falling from her lips, and the way her core clenched tightly around his fingers. - So he picked up his pace, relentlessly thrusting into her until her walls began to flutter around his fingers.

"S-sirus!" Hermione gasped "I think I…I'm…"

"That's it, kitten." Sirius purred, "Be a good girl and come for me."

As if she had waited for his permission, Hermione instantly shattered around him; her whole body twitching and writhing as her orgasm washed over her. Sirius guided her through it, continuing to pump into her until her moans grew quieter and her body went slack.

When he finally pulled his hand away from her, Hermione's cheeks were flushed the prettiest shade of pink and he could see a light sheen of sweat glistening on her forehead as she sank back into the water, looking utterly relaxed and satiated.

She looked stunning like that, and for a brief second he thought that if he could spend the rest of his life with no other purpose than to make her look like this he'd die a happy man.

But it didn't take long for her to come down from her high and the realisation of what they'd just done hit her. He watched as a fierce battle of emotions began to play out on her face; - a mixture of fear combined with shame and regret, as she began to shake her head, eyes wide with worry.

"Oh gods." she gasped, raising a hand to cover her mouth. "Sirius, I'm so sorry! I shouldn't have made you -"

"Shh." Sirius soothed, placing a reassuring hand on her knee. "What are you apologising for, princess? It was me who made the first move, wasn't it?"

Hermione bit her lip, eyes still huge and round, but etched with hope, as she searched his face.

"Did you enjoy it?" He asked, a sudden feeling of panic in his chest. He didn't know how he'd react if she rejected him now.

Hermione nodded quietly, the blush on her cheeks deepening, and Sirius was so relieved, he had to fight the urge to punch his fist into the air and bark out a loud laugh.

"Well." He said, feeling slightly breathless as he pushed himself up from the floor. "Then that's all we need to know for now."

He reached out to caress her cheek, before leaning down and placing a featherlight kiss onto her lips. Hermione instantly leaned into it and his heart roared with triumph at the sound of protest she made when he pulled away.

"I'll leave you to finish your bath." He said, pushing his fingers tenderly through her wet locks, an elated smile spreading on his lips as he began to move away from her. "You know where to find me if you have trouble falling asleep later."

He paused briefly when he reached the door and allowed himself to take one more look at her, his heart full with glee, before he finally turned around and left the bathroom.
