Author's note

This new S/T M-rated fic (which was based on a drabble I wrote a while ago) was written in part to mark Australia Day on 26 January, and also to share some warmth with my shivering friends suffering through a very cold winter in the northern hemisphere. Our lovely couple are living in Sydney and are about to embark on a day of shopping at the post-Christmas sales...

Long hot summer

Sybil lay back in the tangled sheets, her breathing slowly returning to normal. She and Tom were face to face, their naked bodies close together as they shared in the afterglow of their loving. His arm rested around her waist under her body, while his other hand and mouth moved lazily across her skin, which was glowing with the sheen of the summer morning.

She sighed, looking at the clock, and stretched like a contented cat in his arms. "Come on darling, we need to get up and start the day. We've got things we need to do."

"Mmmmm," he mumbled, his mouth on her breast, his hand running down her ribs and gently tickling her side, making her giggle and squirm. "Do we have to?"

"We have to go back to work again next week and you need some shirts. I need a new suit, too."

He leaned up on one elbow and kissed her, before slowly getting out of bed and following her towards the kitchen. They had been married for a few months now, after a romance lasting only three weeks, and he still couldn't believe how lucky he was, to be able to wake up next to her every day...

Tom followed Sybil onto the escalator, grimacing as someone trod on his toe. The post-Christmas sales at David Jones were always crammed with people and this year was no exception.

She walked ahead of him to the rack. "Look, here are a few nice ones - what do you think?"

He grabbed a handful of shirts - they all looked the same to him - and headed to the change room. She sat down on the chair outside, listening to the music piping through the speakers, and recognised an old song from years ago -

"Don't matter what I do
Don't matter what I do
Don't matter what I do
'cause I end up hurting you"

She heard Tom's voice, calling out to her. She looked around to see if there were any busybody salespeople around to stop her going into the men's changing room, then went through the door, whispering -

"Tom, where are you?"

He opened his door a little and waved her in.

"I can't choose, what do you think, love?"

Sybil's eyes opened wide as he casually undid the buttons on the shirt he was wearing and shrugged it off, the sight of his muscular arms and chest setting her heart racing. She couldn't help letting out a little gasp of longing -

"Sybil, don't even think about it. We're already on a warning after last time! Oh hell, twist my arm, come here..."

He pulled her over to him, wrapping his arm around her waist and sliding his fingers into her tousled hair, twisted up on top of her head against the heat. She looked up at him with that look through her eyelashes she knew always drove him crazy -

"Well, if you insist…"

Their mouths met in a kiss and she found herself moaning against his lips as his tongue found hers. She let one hand rest on his chest over his heart, while the other one ran slowly up his bicep before sliding behind his neck. His fingers slid inside her shirt and under her bra, playing with her nipple as he kissed her deeply, his other arm pulling her close to his body...

"Hem, hem!"

They broke apart with guilty expressions on their faces. Bollocks, it's the same guy! Hope he doesn't remember us!

"I hope I don't need to remind you this is a public place, with children outside! Please get dressed and leave, immediately. I don't want to have to involve the police."

Tom quickly put on his shirt and, hand in hand, he and Sybil fled the scene. It wasn't until they were back on the escalator that they turned to each other and laughed -

"Sybil, just wait till I get you home."

His eyes flashed at her and she gave him a cheeky grin as they walked off the escalator.

"Next stop, QVB!"

They made their way through the crowds and into the historic building. After they stopped for a quick lunch, Sybil led him along the ground floor and turned into David Lawrence, a shop she often visited for workwear. She browsed the racks expertly, finding a few things she liked and slinging them over her arm. A salesperson led her to the changing room and closed the door as Tom settled into the "husband" chair.

"Sybil, how are you getting on in there?"

"Be patient Tom - I think you will like it!"

She pushed the curtain aside and came out in a slim fitting grey suit, with a single button jacket and pencil skirt that hugged her curves in all the right places.

He felt his jaw sagging as she twirled around to give him the 360 degree view - Her arse in that skirt! Oh my GOD! Suddenly he felt his trousers getting too tight and he shifted uncomfortably in his chair. She looked into his face and fluttered her eyelashes at him -

"Oh, don't you like it?" Her wink showed him she could see exactly what was going on.

"Sybil, for fuck's sake - I've got to get you out of that skirt right now," he muttered, unable to hide the raging desire sweeping over him as he looked at his wife.

She had a brainwave - "Well, we are in the Queen Victoria Building. They have a ladies room up on the third floor with really big cubicles..." She bit her lip and pretended to look coy - if it was possible, he wanted her even more after that.

"Give the lady your credit card and let's get out of here, Mrs Branson!"

"Your wish is my command, Mr Branson."

She changed quickly and, once they had paid for the suit, they ran to the escalator...

Sybil had a quick look inside - amazingly, the bathroom was empty and there was one door unlocked on the far side.

"Come on, quick, the coast is clear." She beckoned Tom in with a "come here" gesture.

They crept inside the vacant cubicle and closed and locked the door, then turned to look at each other. Their bodies moved as one, coming together in a rush of heat that challenged the baking sun outside. His mouth fell on hers in a searing kiss, ravaging her as he tore off her shirt. She pulled his t-shirt out of his jeans, lifting it over his head as he undid her bra and dropped it in the floor, her skirt and knickers quickly following it.

He grabbed her and lifted her, pushing her naked body against the wall, her sandals falling off her feet as she wrapped her legs around his body. She could feel his arousal pushing hard against her thigh and she whispered in his ear, urging him on.

"Tom, please, fuck me, I need you to fuck me so hard..."

He fumbled to undo his fly, jeans falling to his knees, and freed his cock, already erect and aching for her. He tore open a condom with his teeth and rolled it on, before pushing into her, up to the hilt, filling her completely.

For a moment, they stayed still, staring into each other's eyes, her arms sliding around his neck. Then, eyes still locked on hers, he started to thrust, slowly at first, getting into a rhythm with her as she found her balance against the cold tiles. One hand grabbed her arse while the other was braced against the wall. A deep groan escaped him as they started to move together and she shook her head -

"Tom, shhh, we'll be caught."

Sybil shifted herself to a position where, each time he drove into her, his cock rubbed against her swollen clit, building up an almost unbearable friction almost immediately. She let out a gasp and closed her eyes, biting her lip and tightening her hold on him. She was lost in their shared world of desire and longing, forgetting where she was, forgetting everything but the taste of his lips, the feel of his skin, the blue of his eyes. He murmured to her of how much he loved her, how beautiful she was, how he could never get enough of her...

Tom needed to touch more of her so he braced himself with one leg against the wall before lifting his hand to put it to her cheek. He let his fingers trail slowly down to her throat, running along her collarbone, grazing the side of her breast, following the curve of her waist. He put a finger under her chin and lifted her face to his, kissing her closed eyes before he began to move faster, pushing harder into her.

She began to shiver in his arms and, as she broke apart, she opened her mouth to scream. He was on the verge of orgasm too but he was still enough in possession of himself to remember where they were, and leaned in to capture her mouth with his just as the scream escaped her lips, a sound that rose up from deep inside her, a place she had only ever touched with him.

Her core convulsed around him over and over, and he couldn't hold on any more, coming so hard his knees trembled and he struggled to hold them both up. Her head fell onto his shoulder, her arms and legs locked around him, holding him inside her for a few more moments before he gently lifted her down and found her lips with his. Their hearts were still racing in time as they held each other close...

After a few minutes, Tom lifted his mouth reluctantly from hers and stepped back, tugging off the condom and pulling his jeans back up. Sybil slowly opened her eyes and smiled, flashing him a grin and a hip tilt before leaning down to grab her underwear and starting to get dressed. As she went to fasten her shirt, she saw that half the buttons had been ripped away.

Once they were both dressed after a fashion, he picked up her shopping bags and they opened the door, only to find several curious women waiting outside, clearly only too aware of what they had been doing in there. A uniformed guard stepped forward - Oh fuck, not again! Twice in one day!

"Come on darling, let's go."

Sybil boldly took hold of her husband's hand, holding her shirt closed with the other, and led him through the curious onlookers to the door, pushing straight past the security guard and starting to run as they reached the main concourse, getting lost in the crowds...

"OK, mister - you owe me a new shirt!"

Tom dropped one eyelid in a cheeky wink - "Only to happy to oblige, my love - my only condition is that you choose a shop that has a large changing room."

She swatted his chest - "You're too cheeky for your own good, Tom."

"Just as well you love me for it, isn't it! Come on, you must be tired, Sybil. Let me take you home, give you a foot massage and pour you a large glass of wine."

"Make that two, and you've got yourself a deal."

"Whatever you say, darling. Didn't I once promise you I'd devote every waking minute to your happiness?"

A/N -

Song credit - "Long Hot Summer" by the Style Council. Thanks to angiemagz for the awesome gif I used to accompany this fic on Tumblr and to the Yankee Countess for helping me brainstorm a couple of ideas for it.

I've written quite a few short/one-shot M-rated Sybil x Tom fics in the last few months on Tumblr, and a few people have kindly suggested I bring them together somewhere on ff. This story is the first chapter of that new collection, which I am calling "Tonight or Tomorrow" (again, thanks to the Yankee Countess for the idea for the title!). I plan to add my backset of fics to it from Tumblr gradually, to bring everything together. The stories in this collection will range over different themes and time periods, but the common thread will be that they all celebrate the sexiest couple on Downton Abbey. ;)

Couple of notes on the Sydney locations mentioned - David Jones is the largest department store in Sydney (it's a national chain), while the Queen Victoria Building is a beautifully restored building from the late nineteenth century, which has been turned into a large shopping centre in the middle of the city.

Thanks as always for your support of my writing! Would love to know what you think. :)
