'Turn around, let me see that fat arse,' Lisa was deliberately provocative.

'It's not...,' Sally began to protest but Lisas's glare gaze silenced her. She turned slowly, she hoped elegantly, around and waited for the dominant woman to tell her what to do next, fighting to subdue the trembling which gripped her upper thighs.

'Bend over,' Lisa was impressed. Sally's backside was not small nor could it be called tight, but it was a classic shape, like a pear.

I'm going to enjoy slapping that

She crossed the end of the large boardroom table. Sally was unaware that Lisa was within reach of her when the hand came down and the palm made contact.

'Ouch! What are you doing?' She cried out, turning around and standing, rubbing her smarting buttock through the knickers.

'I should think that was perfectly obvious,' chuckled Lisa, flexing the fingers of her tingling hand. The chuckle died and her face hardened again. 'Did I tell you to turn around or stand up?'

'I'm sorry, I was surprised.' She turned around and bent over again, hands just above her knees. She closed her eyes and prepared herself for another assault,

Lisa waited until Sally moved her head as if to check if Lisa were still behind her, then reached out, hooked her fingers under the waist band of the knickers and gently eased them down.

Despite herself, Sally thrilled at the exposure.

What is the matter with me?

Lisa left the knickers mid thigh. The feeling of the stretched elastic would remind Sally they were there, remind her of the humiliation. She placed the hand which had dealt the slap onto the buttock which had recieved it and gently caressed the fading redness...before walkibg her fingers toward the steep inside curve and dipped into the crevice. Sally gasped...lifting her thighs.

'Does your husband fuck you there?' Asked Lisa.

'We aren't intimate,' gasped Sally.

'Has a cock ever violated you there?

'No, I didn't want it,' she paused, 'do you want to?' She felt Lisa's fingers lifted away...and was oddly disappointed...but only briefly...wet fingers returned...warm saliva was spread by the pad of a finger in tiny circular motions directly onto her puckered hole.

'Do you want to MISTRESS,' corrected Lisa and her finger pressed into the virgin anus like a little cock.

'Oh god, yes,' groaned Sally,'Yes, Mistress...mmm.'

There was a tap on the meeting room door.

'Come!' said Lisa.

Sally froze, her thighs lifted and Lisa's finger inserted in her anus up to the knuckle.

The door opened and an office cleaner poked his head around the door. He took in the scene, eyes wide, not believing the sight that met them.

'Oh, I'm sorry errr...miss.'

He pulled his head back out and the door closed slowly, clicking shut.

'Don't worry Sally,' said Lisa in a comforting tone, 'unless he's seen your arse before he won't have recognised you. I don't care if he recognises me.'

In response, Sally's thighs began to move again.
