Hi, thanks so much for all the lovely comments. Sorry for taking so long to get back to it!xx

~o0o~

Even though she had seen the small flicker of the baby's heart during the scan, there was still a part of Hermione that didn't believe the pregnancy was actually happening. The news of her conception had obviously been spread by Ron and Luna, but the Order members who floated in and out of Grimmauld Place over the next few days were discreet enough not to mention it. Her morning sickness had subsided, and her stomach was still flat – everything was exactly has it had been...except.

'Ow', Hermione winced slightly as she leaned forward to examine an old battered text on runes.

'You alright?' Sirius, who had been keeping her company in the library of Grimmauld Place, was instantly alert.

Hermione rolled her eyes at his chivalry. 'I'm fine,' she muttered, absentmindedly rubbing her chest, 'I just knocked myself off the table.'

Sirius' dark eyes which had been watching her anxiously, now momentarily slipped to her chest, and Hermione felt her face flush with heat. Everything was the same – except her breasts. They'd never been something she'd thought about; they were there, they were small, they didn't get in the way...This morning however she had awoken to find that they had nearly tripled in size, and were so sensitive that she could barely tolerate wearing a bra.

'Well let me know if you need a hand.'

Hermione wasn't sure, but she thought she saw the faint traces of a smirk on Sirius' face. Letting out a deep sigh, she returned her attention to the text in front of her. The atmosphere between her and Sirius had cleared, there was no need to start another fight.

Sirius cast her a sideways look, still desperately trying to hide the smirk on his face as Hermione sighed loudly in disapproval. He was seated on the couch, allegedly trying to fix the clock from the kitchen, which hadn't worked since he was a young child. Instead however, he kept finding his gaze distracted by his pregnant wife, who sat cross legged on the floor, leaning over the coffee table, idly massaging her breasts while she poured through some dusty tomb. She moved slightly to stretch and as she did so she caught his gaze, and flushed bright red.

'Sorry,' he muttered by way of apology, a sheepish grin on his handsome face, 'They've just you know...sprung out of nowhere.'

Beet red, Hermione gave him a haughty look and with a small 'Harrumph', returned to her reading. Her mind was distracted however, and after a few moments her own gaze slid over to where Sirius sat, sprawled out on the couch. Really, she thought in irritation, it was obscene how much space he took up. He lifted his white-tshirt slightly to scratch his toned stomach, and Hermione felt her mouth go dry at the sight of the line of dark hair that trailed from his naval to disappear below his belt buckle...

'Excuse me who's staring now?', there was definite smirk on Sirius' face, and Hermione bristled in irritation.

'I wasn't staring,' she glowered at him, ' I was just thinking that you've far too much time on your hands. Don't you have anything better to do than try fixing that damned clock?'

Srius shook his head slowly, his eyes dancing with mischief. 'As a matter of fact, no I've nothing better to do...and don't lie to me Hermione, that's not what you were thinking.'

Hermione felt herself flush once more, both in irritation and something else - some prickly, gnawing feeling that was both delicious and a torture at the same time.

'Yes it was,' she muttered mutinously, casting him her coldest glare.

But Sirius was not to be deterred, and he rose gracefully from his seat and padded softly towards her. He hunkered down, on strong thighs, so that his face was right next to hers and grinned wickedly.

'I know you're lying Hermione,' he whispered, and Hermione felt her breath catch in her throat, as he continued, 'Tell me what you're thinking.'

'I want to scratch my nails across your stomach,' the words were snatched from Hermione's lips, by the marriage spell that bound her to obedience, and she gave a mortified cry.

'That's not fair Sirius,' she made to whack him forcefully on the chest, but he easily caught her arm in a strong but gentle grip.

His breathing quickened, and he looked at her with eyes that were almost black with lust.

'Tell me what else you want to do,' he whispered against her ear, as with one smooth movement he manoeuvred his body so that it was positioned over hers, and she found herself lying on the carpeted floor.

'I want you to massage my breasts,' Hermione whispered, half mortified – unsure now if she was supplying the information voluntarily or if it was the spell. She was hot, and wet and panting slightly and had never wanted anything more than to feel his hands on her body.

'Like this?' he asked, dropping a gentle kiss on her lips, before snaking his hand up her t-shirt, so that he was softly caressing her breast through her bra. Hermione gave a small moan, and wriggled underneath him.

'Take it off,' she whispered, and with his free hand he waved his wand and whispered 'vestes deponeret', so that her bra, beneath her tshirt, simply disappeared.

His hands slowly circled the sensitive skin of her breasts, and his head bent to claim her mouth in a searing kiss. Slowly, slowly his fingers circled the skin around her nipples, teasing, brushing across them lightly, but never quite relieving the ache that she felt.

'Merlin's beard, Sirius,' she moaned, after a few minutes of this, and she hastily wriggled from beneath him and whipped her tshirt off. With an urgency she had never felt before she wrapped her arms around his neck, pulling him down towards her. His eyes lit up, and without having to be asked he bent his head, to finally claim a nipple with his mouth.

'Oh God,' Hermione gave a small cry of relief, and allowed her hands to wander across his body, and he kissed his way across her skin, from one nipple to the other. Moving her way down slowly, until she reached his jeans and felt his hardness, straining against the fabric.

'Fuck me Sirius,' she whispered, arching her back and wrapping her legs around his waist.

'Are you sure?' he crocked an eyebrow, and she gave him an irritated stare.

'Of course I'm sure, ' she whispered as her hands hastily began to unbuckle his belt. Sirius gave a low groan as her soft hands reached inside and genty began to stroke the shaft of his cock.

'Vestes deponeret,' he whispered again, grabbing his wand and suddenly they were both naked, lying on the carpet of the library.

'You're sure?he asked again as he positioned himself between her legs, the head of his cock softly brushing against her wetness. Hermione didn't answer, merely arched against him, and wrapped her arms around his neck, drawing his mouth towards hers.

Taking this as confirmation, Sirius plunged into her, letting out a soft curse as he did so.

'Fuck, Hermione you're so wet,' he whispered in her ear between kisses, as he moved slowly inside her. She gave a soft laugh, and place her hands on his firm ass, drawing him in deeper, urging him to go faster. Her clit hummed as he moved steadily inside her, and she could feel her muscles contracting.

'Don't stop,' she whispered, drawing him deeper inside her again, as finally the pleasure building inside her peaked, and she came hard. Sirius let out a low growl as he felt the rhythmic waves of her pussy, clenching his throbbing cock – and with one final, deep, searing stroke he emptied himself inside her.

Their breath was ragged, and he stayed inside her for a moment, lying on the floor, softly stroking her face.

'Oh Hermione,' he whispered, dropping a soft kiss onto her lips. Where do they go from here?
