The duke reached out and clenched a hand in her hair, dragging her forwards and onto her knees. She used her free hand to grasp his shaft, marvelling at how its girth dwarfed her small fingers then she bent it down slightly and took a lick. It was the most exquisite taste. Salty, earthy, male and masterful; without even wondering whether she could take him, she opened her mouth wide and slid his cock in. It seemed to touch every part of her gaping lips at once but it managed to slide in and Sarah felt immense pride as she felt the huge thing glide to the back of her mouth. She knew she ought to gag but the sheer pleasure of the moment prevented her, keeping her relaxed.

"She has a natural aptitude Chambers," the duke said from somewhere above her and yet another hot, melting tide of excitement filled Sarah's belly, even as the duke's huge cock began to slowly thrust in and out of her mouth. Each inward plunge drove him further into her throat but her pride in his compliment kept her open enough for him. Further aid came in the form of Mrs Chambers kneeling behind her and reaching round her. One hand roved from breast to breast, kneading, tweaking and pulling, while her other hand went between her legs and busied itself with alternately plunging deep into her and rubbing at her nubbin until she began to moan helplessly around the divine shaft that gagged her.

"Take him down smoothly when he comes," Mrs Chambers whispered in her ear. "Take your Master's gift calmly and gratefully when he's ready to spend."

Both her uncle and the rent collector had used her mouth on the last rent day. But she had been nearly exhausted by the buggery and the beatings and she had snorted and spat the stuff out as she tried to breathe.

This was different. Sarah knew she just had to contain the duke's orgasm. Instinctively she knew that a man of power like him could - on a whim, or in a fit of angry disappointment - cast a woman aside with no more thought than he might give swatting a fly.

In her mouth she felt the duke's cock swell and his rhythm changed. Now his hands clenched in her hair and he began to fuck her mouth in earnest. Despite her best endeavours, she felt herself begin to tense at the thought of thick splashes of sperm erupting into her already-stuffed throat.

"Open to him, my girl," Mrs Chambers whispered and rubbed harder at her clitoris. Sarah moaned in pleasure and drew breath just as she felt the pumping begin.

The power and the domination of the maleness that impaled her almost swept her away as she swallowed gout after gout of thick, pungent sperm.

Before her eyes she saw Mrs Chambers' hand masturbate the shaft of the huge cock.

"Go on, my lord! You can give the little bitch more than that! Fill her to the brim!"

The words combined with the pleasure of the usage to tip her over the edge and as the duke roared in his pleasure so Sarah felt the tides of orgasm wash over her once more as the duke's sperm splashed into her and she took down every drop.

As the duke enjoyed a leisurely glass of whisky once more, he had them disport themselves on the bed. Mrs Chambers' tongue delved deep into Sarah's mouth as they rolled and embraced, eager for any trace of her lord.

The feel of another woman's body against hers; the wetness of the vagina, the softness of the breasts were an exquisite pleasure to Sarah but all too soon the duke's vigour returned and Mrs Chambers was hauled off her to be whipped once more. However, on this occasion, Sarah did far more than merely watch.

The duke took the lash to her back this time and as he worked Sarah knelt beside him and stroked his softened cock back into a size and a hardness that she found incredible, given his efforts so far that night. She also kissed and fondled his balls and let her fingers trail around to his muscular buttocks and find its way between them and eventually a finger found its way into the entrance concealed there.

She loved the way that nothing she did was allowed to interrupt the pleasure he took in belabouring his slave. The hiss and smack of the whip, answered by the increasingly demented and orgasmic cries of Mrs Chambers, carried on with a relentless ferocity that had Sarah squirming and rubbing her thighs together as she adored the duke.

Once again it was Sarah who was fucked when he had become bored with the whip, but Chambers was taken down. And when Sarah found herself on her back, climbing towards yet another climax with the duke ramming himself into her with no signs of fatigue, she reached down to hold his buttocks hard between her spread thighs and found Chambers' head buried between them, tonguing him eagerly as he bucked and roared in his orgasm. Sarah joined her cries to his, drunk on the unbridled depravity of the night.
