  “We’ll start with two on each ass cheek, one just above each clit, and one on each tit. Fourteen nodes, seven a piece. Perfect.”

  Zoe’s breathing began to intensify, her heart racing. She was terrified, and Clare could see it. Finally, the two of them met eyes. Clare gave her a gentle nod – you’re going to be OK…

  Rubin pulled up a small stool and sat behind his box, flipping a green switch. It began to hum, and Zoe whimpered.

  “Not such a tough girl now, are you?” Rubin teased her. She swallowed, telling herself to stay strong.

  “Fuck you,” she said, as Rubin gleefully turned one of his many dials. Zoe winced, hearing the clicking sound of the electricity – but felt nothing. Instead, Clare took the shock, a steady stream of painful electricity straight into the four nodes on her ass. She gnashed her teeth against her ballgag, eyes clenched shut, grunting in pain.

  “Stop it!” Zoe screamed, “I’m the one you want to hurt!”

  Rubin laughed at her. “Clare was right. She said you were a loyal pet. That’s very good, slut.”

  With that, he flipped another dial, and Zoe felt her ass clench involuntarily, jolting her hips forward, the searing pain of the electric current pouring through the nodes on her cheeks. She cried out, her face contorted with pain.

  After a few moments, Rubin cut both of their dials. Both women’s legs slumped, numb from the shock, their wrist chains the only things keeping them from collapsing.

  Rubin smiled at Zoe. “Now that you’ve had a little taste, here’s how this is going to work,” he began. “You’re going to beg me to fuck you in the ass. You’re going to convince me that you want it, that you need it. Make me believe that you want to be my dirty little fuck slut. Until then…”

  He turned his dials, sending electricity coursing through Zoe and Clare’s clit nodes, causing both of them to holler and moan in agony.

  “…the two of you are going to hang here and sizzle.”

  Rubin watched them squirm for a few moments, then turned their voltage up even higher, bringing about even louder wails from both women.

  “I love it,” he said to himself, giddy, “I turn the dial here, and get the reaction there.”

  “F-Fuck y-you!” Zoe screamed. Rubin flashed a toothy smile before turning more dials, activating the tit nodes as well, sending current alternating between their left and right breasts in short bursts. Each one felt like a punch to the chest to Zoe, knocking the wind out of her, her clit still scorching from the crotch node. Still though, she refused to give Rubin what he wanted.

  “Pretty tough, I’ll give you that, slut,” he said, casually cranking up the tit dials, causing each shock to feel like needles drilling into Zoe’s flesh. She screamed in pain, her eyes rolling back in her head, her body twitching from each and every volt.

  Finally, Rubin cut the power, and both women slumped again. Zoe panted for breath, shivering uncontrollably, and looked up at Clare, out of breath and disheveled, a long stream of drool dripping down from her ball gag.

  “Sooner or later,” Rubin started, “I’m going to break you, just like she did.”

  “I can do later if you can,” Zoe said with a defiant smile, spitting at Rubin’s feet. Rubin grinned back at her.

  “I can see why Clare likes you so much,” he said, before flipping a dial and sending electricity ripping through Zoe’s clit and ass. She gritted her teeth, determined not to scream, tears beginning to stream down her face. Clare, unaffected, could only watch her girl suffering bravely.

  “You know, slut – this is only 40%...” Rubin taunted, cranking the dial up. Zoe’s eyes went wide, and she saw stars as her entire midsection jolted with electricity, her cunt throbbing with pain, her clit on fire. In spite of her best efforts, she cried out, moaning in anguish.

  “…and that’s only 60%...” Rubin added, before cutting the power and slapping Zoe’s ass, hard.

  “Such a tough slut, I love it,” he said, delighted. “Now you know you can end this. All you have to do is say the magic words, ‘Please sir, fuck me in my tight, slutty ass.’” Zoe said nothing, panting for breath, her head hung low. Rubin tsk tsked, then flipped the switch – sending electricity pouring through all seven of Clare’s nodes.

  Clare’s entire body tensed, her shoulders jolting back and forth as the tit nodes alternated their current, each hit knocking her back in pain.

  “Let me show you what 80% looks like,” Rubin said, devilishly cranking up the juice on the box. Clare instantly screamed a loud, agonizing shriek through her ball gag, her body shaking, tears flowing down her face.

  Rubin turned to a horrified Zoe. “Wanna see 90%?” He asked.

  “Please… please, just stop,” Zoe begged.

  Rubin’s eyes lit up. “Oh, so now you feel like begging,” he exclaimed as he turned on Zoe’s tit nodes. “Let’s give you a little taste of 80% and see how much you beg then.”

  He turned the dial up, and Zoe screamed, the tendons in her neck completely tense, her face flushed red. She managed to open her eyes, looking over at Clare, still enduring the intensity of the full body shock.

  “P-please… p-please stop…” Zoe stammered.

  “Those aren’t the magic words, slut,”

  “Please f-fuck me…”

  “You can do better than that, cunt,” Rubin said derisively. “Now let’s hear you beg for it.”

  “Please! Please,” she moaned, “fuck me in the ass!”

  “Your tight, slutty ass,” Rubin corrected, turning Zoe’s ass nodes on to 80% as well. Zoe screamed again, then struggled to continue.

  “…in m-my tight….slutty… ass…” she yelled out.

  “Gotta say it all,” he said teasingly, eliciting a wail of despair from Zoe. “Maybe watching your dear mistress fry at 90% will motivate you.” He cranked up Clare’s dials, her screams growing even louder.

  “PLEASE!” Zoe begged, “Fuck my tight, slutty ass!”

  “You didn’t say sir,” Rubin said, turning on Zoe’s clit node, “Do it again.”

  Zoe screamed in a combination of pain and frustration, shooting one more look at Clare, wriggling in agony, moaning uncontrollably into her gag. Zoe gasped for air through the pain, then shouted:

  “PLEASE SIR! PLEASE! FUCK MY TIGHT LITTLE FUCK SLUT ASS! PLEASE!”

  Rubin laughed a sadistic laugh. “Close enough,” he said, cutting the power to both women, leaving them both dangling and completely drained. Zoe sobbed, watching as Rubin removed Clare’s ball gag.

  “You suffer so beautifully, girl,” he said gently, kissing the top of her head.

  “Thank… thank you, sir,” she answered weakly, drool still dripping down from her chin.

  He turned to Zoe, pushing the large, purple ball into her mouth and clasping it tightly behind her head.

  “Matches your hair,” he said. “Cute.”

  Zoe whimpered, too exhausted to put up any further resistance. Rubin had been right, she realized. He was going to break her, and there was nothing she could do about it.

  She turned and locked eyes with Clare. From behind Rubin’s back, she silently mouthed two words:

  “Good girl.”

  No, Zoe thought, tears streaming down her cheeks, I’m a dirty little slut. And Zoe heard Clare’s words about dirty little sluts echoing in her head.

  “They get fucked.”

  **********

  Rubin unchained Clare, guiding her to the corner of the room. “Kneel,” he commanded, and she obediently dropped to her knees, facing the wall, hands behind her back.

  “No,” he told her, “I want you to watch.” She turned around, facing Zoe. They stared at one another, Zoe still struggling to understand why Clare had betrayed her, and why, in spite of this, she had remained loyal to her as they were being tortured.

  Rubin turned the crank and lowered Zoe’s wrists, then re-cuffed her arms to the chain behind her back. Then, he hooked another chain to the ring on her collar, using it to pull her down, bending her over at th
e waist, her wrists in the air above her back. He hooked the chain to the floor, effectively immobilizing her.

  “Perfect,” he said, smacking her ass.

  He moved behind her, crouching down, his face inches away from her defenseless, open ass. He looked at it, inspecting his new prize, a smile on his face.

  “Such beautiful welts,” he told Zoe, running his fingertips over her ass cheeks, turning his eyes to Clare, “Looks like someone had fun.” He traced a finger down her crack, settling on Zoe’s hole, rubbing it in a circle, feeling its elasticity.

  “Yeah,” he said, “Clare told me you were tight. Hasn’t stopped me before though, don’t you worry. Shit, just ask her.”

  Zoe watched as Clare swallowed, her mouth dry.

  Rubin moved the box, still wired to Zoe, directly under her head. “Come here, slut,” he said to Clare, who obediently crawled over, kneeling directly in front of Zoe, the two of them eye to eye. “Go ahead and warm her ass with some more electricity while I get ready. Nothing crazy.”

  Zoe stared defiantly at Clare, refusing to show emotion. Clare matched her, her face expressionless as she turned the dials, sending the electricity coursing into her ass. Zoe, braced for pain, whimpered and rocked forward slightly at the clicking sound of the current, but quickly realized that the shock was quite low, especially compared with the vicious 90% stream she had just endured. In fact, it was more tingly than painful, with pulsing bursts of light electricity numbing her ass.

  “See?” Rubin said from behind her, “It can feel good, too.”

  Zoe closed her eyes, trying to block out the fearful thoughts of Rubin’s cock mercilessly pounding her ass. She could hear his clothes coming off, and knew that it wouldn’t be long now… all she could do was endure it. In spite of herself, she found herself imagining Clare’s voice. “That’s a good girl…” it said. “Everything will be OK…”

  As if reading her thoughts, Clare reached out, gently stroking Zoe’s cheek. Zoe opened her eyes again, trying to read Clare’s face. The only thing that came to Zoe’s mind was, Mommy’s right here…

  Naked now, Rubin walked over to the table, back into Zoe’s sight line, squatting down to root through a drawer. She could see his tan skin, his muscular build, and the thick but soft-looking hair covering his legs and ass. He was actually quite attractive, but that was the last thought she wanted in her head. She pushed it as far out of her thoughts as she could.

  Finally, he found what he was looking for, and stood up, turning around; in his hand – a large, thick, black, cock-shaped strap-on. Oh God, Zoe thought, he’s going to have Clare fuck me. She was actually thankful – she knew Clare, and even though she was furious with her, she knew she wasn’t as afraid of her as she was of Rubin.

  Then, Zoe noticed Rubin’s scars – one under each of his pectoral muscles. She furrowed her brow, confused, then lowered her gaze down his body, finally seeing…

  Oh my God, she suddenly realized. He has no dick.

  Rubin smiled at her, noticing her wide-eyed expression. “Don’t worry, slut,” he said, holding up the strap-on with a grin, “Where there’s a will, there’s a way.”

  Rubin was transgendered, Zoe now realized, female-to-male. She watched as he fastened the strap-on between his legs, then lubricated the dildo. Thank God for lube, she thought.

  He moved behind her, giving her ass another hard slap, then crouched down again. “Let’s see how you taste,” he said, before leaning in and burying his face between her cheeks, rimming her, licking in firm, broad licks. Not able to help herself, Zoe moaned into her ballgag – nobody had ever rimmed her before, and much to her surprise, it felt good. Not even good, she thought – it felt great. She moaned again, louder, as Rubin worked his tongue into her ass, the combination of his wet, slippery tongue teasing her hole and the low, steady electricity entering through her cheeks driving her mad with shameful pleasure. She moaned again, angry at herself for giving him the satisfaction of knowing he was making her feel good. The frustration, the helplessness – it all just made matters worse, just as it had with Clare. God, Zoe wondered, am I actually getting wet? Is this turning me on? Do I actually want him to fuck me?

  She didn’t want to know the answer to those questions, especially that last one.

  “All right, slut,” Rubin, said, pulling his face away from her ass, “I think it’s time you got fucked. Does Daddy’s little fuck slut wanna get her ass reamed?”

  He smacked both of her ass cheeks, hard enough to leave bright red handprints, hard enough to make her squeal. “I didn’t hear an answer, slut. I said,” SMACK! “Does Daddy’s little fuck slut wanna get her ass reamed?”

  Zoe could only moan unintelligibly through her ball gag.

  SMACK! “I can’t understand you, slut!” he yelled, pushing the tip of the dildo up against her hole, “Does Daddy’s little fuck slut want to feel Daddy’s big black cock deep up her ass?” SMACK!

  Zoe moaned again, the painful sting of the slaps turning her on like nothing else.

  “Answer me, slut!” He yelled, thrusting lightly, teasing her hungry asshole, threatening to penetrate it at any moment. “You want your ass fucked hard, don’t you?” SMACK!

  “Don’t you!?” SMACK!

  Zoe couldn’t help it – she practically screamed out, “Mmmmm-hmmmm!” through her gag.

  And with that, he penetrated her with one smooth thrust, her ass stretching and expanding to accommodate this invasion. She wailed into her gag, and Clare quickly wrapped her arms around her, holding her head tight to her breasts and stroking her hair.

  Rubin held still, the dildo just over halfway up Zoe’s ass, giving her a moment to adjust. “Breathe, girl, breathe,” he said gently. “Relax… and take it.” Slowly, he pushed in deeper, and Zoe grunted at the sensation. She cringed, feeling strangely emotional, as feelings of shame, humiliation, and helplessness washed over her. At about three quarters of the way in, he began pulling back, slowly exiting her, smiling at the sight of her stretched hole flexing as the last of the tip came out.

  “Such a good girl,” he cooed. “Such a good little slut.”

  He rocked forward, entering her again, harder this time, testing her. She grunted with exertion, still not used to the feeling, but enduring it.

  “Just breathe,” Rubin said again, “your ass can take it.”

  He started working it in and out, slowly fucking her now, reading her body and responding to her cues. Gradually, her moans became less and less pained, and more and more aroused. Zoe couldn’t believe it – she was starting to enjoy this. The thought simultaneously horrified and excited her.

  Rubin read her signals, gradually increasing the intensity, speeding up his rhythm, pushing the dildo deeper and deeper into her ass. Soon, he was burying it up her tight hole, reaming her ass with firm, quick, deep thrusts – and she was taking it, just like he said she would.

  “Daddy’s little slut likes getting fucked in the ass, doesn’t she?” Rubin teased, smacking her ass again. Zoe felt her resistances crumbling.

  “Mmmm-hmmm,” she moaned out through the gag.

  Rubin grinned, wondering how far he could push this new toy. “Yeah, of course the dirty little fuck slut likes it,” he said, giving her another hard smack. “And she wants it even harder, doesn’t she?”

  “Mmmm-hmmm…”

  “Doesn’t she?!” SMACK!

  “Mmmm-hmmm!”

  “DOESN’T SHE?!” SMACK!

  “MMMM-HMMM!”

  Fucking Zoe with nearly all of his force now, he locked eyes with Clare. “Take her gag off,” he commanded. Clare unfastened it, letting it fall to the floor, along with the drool that had accumulated in Zoe’s mouth.

  “Beg me to fuck you harder, slut” He yelled. Zoe, her mind plummeting deep into subspace, immediately obeyed, yelling,

  “Please sir, fuck my ass harder!” Rubin began throwing all of his might into his thrusts, plowing the dildo in and out of her ass. Zoe’s mouth hung open – she wanted to screa
m with ecstasy, but no sound would come out.

  Instead, Clare leaned in, kissing her. Zoe couldn’t have resisted if she wanted to, immediately sliding her tongue into Clare’s mouth and kissing her back as passionately as she could, filling her mistress’ mouth with her moans.

  Clare released Zoe and laid down on her back in front of her, lifting her legs up and wrapping her thighs around Zoe’s head, pulling the girl’s face down between her legs. Zoe needed no invitation, quickly burying her mouth in Clare’s sweet, wet pussy, voraciously kissing and licking her mistress with a relentless, primal hunger. Clare tilted her head back, letting out a deep, long moan that filled the room, and began thrusting her hips upwards, grinding her crotch across Zoe’s face.

  Rubin smiled at the sight, and began grunting with exertion, sweat beginning to bead across his face from the unwavering rapid-fire thrusting. His rhythm began to slow, each thrust punctuating the last. He reached out, taking Zoe’s outstretched hand in his – she clenched it, squeezing tight in rhythm with Rubin’s dying thrusts. Slowly, he came to a stop, working the dildo up Zoe’s ass one last time, all the way to the hilt, holding it inside of her, his hips quivering with exhaustion.

  At that moment, with Zoe moaning uncontrollably into her pussy, Clare climaxed, her clit bursting with an overwhelming flood of pleasure. She squeezed her thighs tight around the sides of Zoe’s head, clenching her face in close as she orgasmed. Rubin tore the electrodes off of Zoe’s cheeks, then slowly pulled the dildo out of her ass. She gave a loud, shuddering gasp at the bizarre feeling of the inner wall of her ass suddenly contracting. Rubin wiped the sweat from his brow, smiling down at this submissive young thing, broken down into a perfect fuck slut, her defenses shattered.

  Clare lowered her legs, releasing Zoe’s head from her thighs’ insatiable clutches, smiling at the sight of her own wetness dripping off of her pet’s lips. Zoe bowed her head, sweaty, exhausted, and out of breath, the entire bottom half of her body numb from pain, exertion, and ecstasy. She realized that she had orgasmed from the ass reaming Rubin had just given her, an ass reaming she had been terrified to receive, given to her unwillingly by a man who frightened and enraged her. Her head was floating with emotions, as if she was experiencing them all at once and couldn’t decide which one to grasp on to.
