A short walk down the hall from the dining room and up the stairs, Andrea and her temporary mistress arrived at the guest bedroom. As Madelyn opened the door, Andrea saw that her slave had been busy. All of the packages she’d brought in had been unpacked, clothes neatly folded in the closet and dresser, tomorrows outfit already lying out, cleaned and pressed, and the empty suitcases tucked neatly in a corner.

The girl herself knelt by the bed, arms folded behind her back, head bowed. From her stiff posture, she might have been kneeling like that, waiting patiently for her Mistress’ return since before dinner. A slave herself, Andrea knew that looks might be deceiving, but looking at the other girl, she wondered if she had been kneeling like that the whole time, rather than listening at the door, only getting ready when she heard someone coming.

“Prepare her.” Madelyn said, leading Andrea over to the kneeling slave. From a pocket, she pulled out a ring of keys, fitted to the locks of Andrea’s shackles, Andrea guessed.  

“ysss ssssttrrsss…” The other girl slurred around her jaw-crushing ballgag, rising to her feet, somewhat stiffly. One hand came around front and grabbed the ring of Andrea’s collar. With a tug, more gentle than her owner’s, the slave led Andrea over to the bed. With a soft press on her chest, the other girl ordered Andrea to remain still while she crouched down. Andrea gave a quiet sigh of relief as the shackles around her wrists and ankles were unlocked and pulled away.

Her relief was, as always, short lived. The other girl took her in hand once more, pulling the other slave to the bed, so she was lying in the center, on her back. One at a time, Andrea’s limbs were guided to one corner of the bed. Like the Master Bedroom, the furniture in the guest rooms were amply furnished with restraints for securing slaves. In no time, Andrea was once more shackled down, now spread-eagled on the top of the bed.  

Madelyn, meanwhile, had left the room to prepare herself. After Andrea had been shackled to the bed for a few minutes, the other woman returned. She’d removed her dress and was clad in black silk garters, lacy black panties and a matching bra. Walking over to the bed, Madelyn knelt over Andrea, who was squirming, uncomfortably.

Since her enslavement, Andrea had been whipped and flogged, dripped with hot wax, clamped in very uncomfortable places and much more, sometimes as punishment for failing to obey her masters, sometimes simply for their enjoyment. She knew, intellectually, that such was just a slave’s lot in life. There was little she could do, but try and avoid what punishment she could, and endure as best she could whenever the Master wanted to get out the crop and candles for an evening’s fun.

Try as she could, though, Andrea couldn’t stop herself from trembling a little, especially now, with this cruel woman looking down at her with a predatory look Andrea hadn’t seen since her time in the training camp, when the terrifying Mistress Knight had been tasked with breaking her and her sister Lisa.

“My brother is very lucky to own you.” Madelyn said, reaching down with both hands to grope Andrea’s ample chest. Andrea stifled a moan as the other woman started to massage her naked breasts. “I’ll try and enjoy you and your sister as much as I can while I’m here.” Without warning, Madelyn suddenly pinched both of the slave’s nipples, as hard as she could. Taken by surprise, Andrea gave a sharp cry of shock and pain.

“You scream so lovely, slave Andrea.” Madelyn teased, returning to her groping. “I’d like to let you scream aloud, but I suppose it wouldn’t do to disturb my brother while he’s enjoying himself.” Raising one hand, she snapped a finger. As if anticipating her Mistress’ whim, Madelyn’s slave appeared, holding a large ballgag in both hands, offering it to the other woman. Andrea gave a quiet moan. She was well used to being gagged with such devices, but this one looked especially large and uncomfortable.

“Hmmm…” Madelyn hummed to herself, giving Andrea’s abused nipple another pinch, drawing another yelp from the slave. “Might need some additional muffling.” She scooted back, off of the bed and stood at the foot. As Andrea watched, warily as one might watch a cobra that could strike and hurt her at any moment, Madelyn reached down and hooked her thumbs under the band of her panties. Giving the slave a leering grin, Madelyn slid her underwear down her legs, wiggling her ass playfully, before stepping out.

“This should do fine.” Madelyn said, climbing back on the bed, balling the panties up in her hand. “In my household, my slaves must beg for the honor of having their Mistress’ panties in their mouths. Beg for it, my lovely slave.”

Andrea fought to keep her thoughts off her face. This was something she’d not experienced during her time as a slave and her stomach heaved at the thought of having the balled-up underwear filling her mouth. But she also knew, as a slave, she had no say in the matter. Sooner or later, Madelyn would gag her with those panties, the only question was whether she would be angered by Andrea’s refusal, and punish her all the harder for it.

“Please Mistress!” Andrea begged, trying to make her pleas sound as genuine as possible. “This slave wants to be gagged with your panties. She wants to taste her mistress’ panties. Please stuff them into her mouth.”

Andrea’s pleas were quickly answered. While still in mid plea, Madelyn dropped the wadded-up cloth into the slave’s open mouth. Playfully, she reached down with one finger and poked them past Andrea’s teeth, until the ball of cloth was completely inside her mouth.

Andrea fought back the urge to spit them out at once, but to her relief, they weren’t as bad as she’d feared. Madelyn wasn’t the kind to do any sort of work, not when she had slaves to wait on her, so she hadn’t sweated into the panties at all. The wad of silk was even perfumed, filling Andrea’s mouth with a strong floral scent and, beneath it, evidence of how excited Madelyn was at what was coming.

Turning, Madelyn took the ballgag from her slave, turning back to Andrea. “Open wide.” She ordered. Andrea lifted her head, straining her jaws as far apart as she could, trying to get them around the jaw-crushing rubber ball. It took some effort, but finally the plug popped behind Andrea’s teeth. She groaned, her distress made silent by the rubber and panties filling her mouth completely as Madelyn pulled the straps behind Andrea’s head, threading one through the buckle. Madelyn yanked the strap tight, drawing another low groan from Andrea as the gag was forced deeper into her mouth, increasing the strain on her jaws, before buckling it on securely.  

As Andrea chewed on the rubber plug wedging her jaws apart, praying she wouldn’t have to endure this cruel muzzle for very long, Madelyn reached down and seized the slave’s breasts by her nipples again and pinched, even harder this time. Andrea gave another sharp cry of pain, but the gag did its work, reducing her scream to little more than a quiet whimper.

“Excellent.” Madelyn said as tears welled in Andrea’s eyes. “Now let’s begin.” Once again the Mistress held out a hand to her waiting slave. A long, supple leather riding crop was placed in her palm. Madelyn swished it through the air a few times over Andrea’s face, testing the balance and letting the helpless captive see the instrument that would be used to torment her soon, letting her anticipate the pain it would soon spread all across her helpless, bared body. Andrea tensed, steeling herself as her whipping began.

It started slowly at first, Madelyn lightly rapping the tip of the crop across Andrea’s breasts, circling around her much abused nipples, warming the skin and readying it for the stronger blows that came a moment later, sharp strikes, first on the left breast, now the right, then the left again, and on and on. Andrea managed to keep quiet the first few blows, but by the fourth or fifth strike, she cried out into her gag. Her naked body writhed on the bed, straining against the shackles on her hands and feet yanking her down each time she jumped up in shock at the stinging pain of the crop.

Just when Andrea didn’t think she could take anymore, Madelyn backed off. She went back to the light, almost gentle rapping of the crop, now along Andrea’s taut, smooth belly, circling the neat dot of her navel. Again, Andrea tensed, knowing what was coming. Again, the blows rained down harder, causing the captive to scream and buck across the bed underneath her cruel mistress. By the time this flurry of punishment ended, Andrea was in tears. She looked up, beggingly at her Mistress, eyes wide with fright as the light rapping resumed, following the crop’s downward progress and preparing her naked, spread thighs and the delicate slit of her sex for punishment. The cruel leering on Madelyn’s face as she worked up to the punishment told Andrea she would find no mercy tonight.

After whipping her thighs and pussy, Madelyn went back to Andrea’s breasts, which had not yet recovered from their earlier punishment. She worked her way back down to the slave’s sex, then worked her over breast to pussy a third time. By the end, Andrea’s tanned skin was slick with sweat and stripped all over with the red marks of crop. Her whole front was extremely sensitive, causing her to moan and wince as Madelyn reached down to grope and caress her breasts and sex, roughly squeezing and pinching like before.

“Now for the real fun.” Madelyn whispered. Andrea felt her hands withdraw. The slave was too busy with the aches and pains of her punishment, she didn’t notice the Mistress climb off the bed, until she returned, once more kneeling over the spread, prone slave. When Andrea looked up again, she saw Madelyn had buckled some sort of leather belt around her waist. It held a large, double-ended dildo, twelve inches long and at least two inches in diameter. Madelyn inserted one end into her own sex, which was quite hot and moist from her enjoyment whipping Andrea and anticipation of this. The other end was positioned against the lips of Andrea’s own, sensitive, stinging sex.

Madelyn paused, enjoying the look of distress on the slave’s face for a moment longer before she leaned in, her weight sending the strap on plunging into both Andrea’s and her own sexes. Both women moaned loudly, Andrea’s pain from the cropping mixed with pleasure, Madelyn’s pure pleasure.

Leaning close over Andrea, Madelyn rocked her hips back and forth, pumping the strap on in and out rhythmically. Her hands found Andrea’s battered breasts and pawed at them, rubbing the red, sensitive orbs against her own breasts as both gasped and moaned.

Then, without warning, Madelyn quivered, trembling as she climaxed. Andrea gave a quiet murmur as the furious pumping ceased. The captive woman squirmed, so close to release as well. She bucked her hips, trying to get herself off even as the strap on was slid out of both women, only to be disappointed. Madelyn took little notice of the slave’s discomfort, took no notice at all, really, of her as she climbed off the bed. The slave girl was a tool, a living sex toy, to get her sexual pleasure from. That accomplished, Madelyn didn’t really care for the toy’s pleasures or needs.

Andrea grumbled through her gag as the other woman turned and went out of the room. She squirmed, rubbing her butt on the bed, damp with the juices of both women. Were she not chained down, Andrea might have been able to work herself to orgasm in the few minutes the Mistress was out of the room. She glanced over at Madelyn’s slave, still kneeling in place, waiting stoically for her next instruction, silently begging the other slave to help her, to no avail.

A few minutes later, Madelyn returned, having removed the strap on and changed into a silk nightie. She climbed onto the bed, laying down beside Andrea. Snuggled up next to the naked slave, sheets were unnecessary. In moments, Madelyn was fast asleep. Her slave moved to the foot of the bed, curling up on the floor there, close by should her Mistress need her services. Andrea, stretched out by the shackles on her hands and feet, with the uncomfortable ballgag still wedged between her jaws, had more trouble getting comfortable and drifting off. Her loins still burned with how close she’d come, only to be denied orgasm at the last moment. Andrea knew she would have no chance to scratching that itch during the night, during the next day, unless she was able to find a quiet minute to slip away from the Master and his guest, find an isolated corner of the house and be quick with her fingers.

Andrea sighed. Such was the life of a slave…
