Author's note -

This story was born from an M-rated ficlet I published on Tumblr, inspired by an amazing picture from my very talented friend angiemagz of Sybil and Tom in a hotel room. From there, it developed a life of its own. Now publishing it here - thank you to everyone on Tumblr who read this and encouraged me to write more!

I really look forward to hearing what you think - I would love it if you left a comment, if you can. :)

Scene 1 - Threadneedles Hotel

"You know the rule, Branson – buy side and sell side don't mix socially during a deal. Anyone breaks that rule, they're fired. No discussions, no excuses, absolutely no fucking exceptions."

His boss' words rang in Tom's ears as he sat on the bed in his hotel room. He was an experienced transaction lawyer – he knew how these things worked. The chemistry between him and the banker for the other side had been incredible from the minute they met at the official client function to kick off the deal, but he also knew that she was meant to be totally off limits. If his client or his boss found out what had just happened, he would be handed his bollocks on a plate.

Sybil stood in front of the mirror in a pale lavender satin slip, the long waves of her hair tumbling loose down her back. She looked like a goddess to him in the dim light of the room as she smiled, twisting to and fro as she posed for the mirror. He remembered the feel of her toes sneaking up his trouser leg under the table whilst the clients talked about IRR and hedging forex risk, her legs wrapped around his waist in the lift when they couldn't wait to get up to his room, her nails digging into his back as they fell into bed together, her lips against his as they shared a shower afterwards.

She felt his eyes on her – "Penny for them?"

"Just thinking how amazing you look – come here."

She crossed the room and he took her hand, pulling her onto his lap and slipping his arms around her waist. Nuzzling her neck, he nipped a sensitive spot he'd discovered just above where her collarbones met, and felt her shiver.

"Tom, we can't – we've got to get back to the clients – we've already been gone for nearly an hour! If we get caught, I don't even want to think about what would happen."

"Five more minutes," Tom mumbled, sliding the straps of Sybil's slip off her shoulders, leaving her half naked as his mouth moved down towards her breasts. He took her nipple between his lips and she let out a low moan, running her fingers through his hair to pull him closer as she arched her back.

Oh, what the hell! She sat up and straddled him as she pushed him onto his back on the bed – "Maybe we don't have to go just yet..."

Running her hands down the front of his trousers she could feel his cock was already hard, desperate for release. She pulled down his zipper, letting him spring free. Her hand ran up and down his shaft and she leaned in to kiss the tip and slide her tongue along his length, evoking a deep groan that rumbled all through him. Smiling, she moved herself up his body and pulled her slip over her head. His eyes were on her again as she lifted herself up and waited for a moment – then, his hands grabbed her hips and guided her down so she could fit herself onto him perfectly.

Sybil began to move, her breasts rising and falling as she settled into a rhythm, grinding her hips into his. He moved one hand to slide it in between them, finding her clit and starting to stroke it. She shifted her position slightly as she felt his touch, wanting his cock to be even more deeply inside her, and quickened her pace, totally absorbed in the exquisite sensations sweeping through her. Still so aroused from their earlier lovemaking, she knew it wouldn't take much more for him to send her over the edge.

Tom couldn't get enough of watching her like this. He thought this was his favourite position with her so far, because of the way her beautiful body was totally revealed to him. She began to breathe faster – "Tom, oh God, please Tom!" – and in a few moments he felt her clamp down on him as her orgasm raced through her and, head thrown back, she let out a cry he was sure they would hear in the corridor.

He felt himself coming soon after, as she fell down on top of him. He ran his hand up and down her back, placing a kiss on the top of her head and breathing in the vanilla scent of her hair. Sybil moved up his body, kissing his chest and biting his earlobe before finding her way to his mouth. She sighed as her lips, swollen from his kisses, met his. His tongue slid into her mouth, stroking hers, and she closed her eyes and sank into his embrace for a few more minutes.

After a while, Tom reluctantly broke their kiss. He looked at her face and felt his heart skip a beat - Christ, she is so beautiful.

"Come on – we really have to go this time!" She stood up, pulling him to his feet beside her and kissed him deeply, grinning as she walked away from him, then turned back – "How did I end up with no clothes on while you are still dressed? Next time we need to redress that balance, I think."

"Next time? Sybil, you know as well as I do – there can't be a next time, at least not until this deal is over."

"Oh really – are you sure about that, Mr Branson?" She dropped her eyelids and looked up at him through her long eyelashes, pouting and running her hands down her body to tease him, stopping to stroke her breasts and play with the nipples – "Ohhhh, that feels so good..."

"OK, yes I am full of crap – I will be counting the minutes until I can be with you again like this. But for fuck's sake – we have to be so careful – neither of us can afford to get the sack right now with the economy in this state, and for something like this – we'd lose our reputations in the City too."

"Do you think I don't know that, Tom? At least you're a partner at your firm – you have a bit more leverage than I do at the bank – I'm only an associate. Believe me – I knew what I was getting into when I came up here with you tonight – you don't have to tell me!"

She was totally unselfconscious as she stood naked before him, face flushed and ready for an argument. He felt his desire for her, so recently sated, flare up again.

"Umm, what were you saying about next time?" he said, as he pulled off his tie and stepped towards her, his arms sliding around her waist to tangle in her long hair and tilt her head back so he could kiss her throat. Feeling her arms move around his neck – let them wait, she's worth the risk – he forgot all about work as they fell back onto the bed again.
