Ellie smiled at her reflection in the full length mirror, making the final adjustments to her outfit. She needed to look the part for her customer meeting today - smart, professional and businesslike. The tailored dress with a flared skirt that stopped just above her knees seemed to do the trick. Who said a manager couldn't dress pretty for a meeting?
Turning around so her back faced the mirror, she lifted the skirt to her hips to check the most important part of the outfit. This part had nothing at all to do with the business meeting and everything to do with her plans for afterwards. It was Sam's birthday today and she had a surprise for him.
She turned her head to see the view. The summer was warm enough to not wear stockings, and her eyes followed the curve of her smooth legs right up to her ass cheeks. Normally she'd wear small lacy pants under a dress like this, but today she was forgoing any underwear. The only decoration was just barely visible between her round cheeks; a small, bright stone from the plug nestled tightly in her ass. Just the thought of going commando was keeping her in a heightened stage of excitement, and the constant feeling of the plug made her legs tremble when she tensed.
She smiled and smoothed the skirt down, walking downstairs slowly to pick up her bag and approach the car waiting outside.
'Good morning Ellie, looking smart!' Sam's smile and welcome made her clench her muscles in anticipation - an entirely pleasant feeling.
'Morning Sam! Happy birthday!' Ellie grinned at him as she got into the passenger seat. 'Kind of a shame you have to work today, huh?'
'It's not so bad,' he replied, starting the engine and setting off on the short journey to the customer site. 'At least we get to do this meeting together.'
'It'll be over quickly.' she reassured him. 'And anyway, I have a present for you to look forward to afterwards.'
Sam glanced at her briefly, not wanting to take his eyes off the road for too long, but also wanting to catch her meaning. She flashed him a cheeky smile and placed her hand on his upper thigh, squeezing slightly.
'But I don't want to ruin the surprise. All in good time.'
Ellie could feel his cock hardening slightly in his jeans. She brushed the tip through the stiff material and enjoyed the appreciative sigh he gave her in return.
'Mmm then I'm excited to know what it is.'
'You'll find out soon enough, promise.'
Seeing the entrance to the customer site, she reluctantly removed her hand from Sam's leg. Sam found a parking space close to the entrance, and they walked to the reception. Today, their meeting was on the top floor, so the receptionist showed them the way to the elevator. To Ellie's delight, they were the only two people in there. She decided to take her chance.
The doors had barely slid closed before she moved close to Sam and whispered in his ear.
'This is your present...'
She guided his hand under her skirt and up the back of her legs, moving them slightly apart so his hand could explore on its own.
Sam's breathing was quickening, unsure of what Ellie had in mind. His hand reached her round ass cheeks, stroking across them to feel the smooth skin. He stopped the movement when he realised.
'God, you're not wearing anything.'
'That's technically not true,' Ellie whispered, shifting slightly so that his hand brushed the end of the plug.
It took Sam a small moment to realise what he was feeling, then Ellie felt his understanding as he pulled her closer to him.
