Chapter 18: Mark's tongue darts between Emily's slick folds as Sarah adjusts the voltage dial, his saliva mixing with her arousal in obscene, glistening strands. 'Too slow,' Sarah purrs before pressing the button - Mark's body jerks violently as electricity courses through him, his scream muffled against Emily's pussy while she moans above him, grinding harder against his punished mouth.
The shock collar was cold and heavy around Mark’s cock, a stark black band against his pale skin. Sarah adjusted the remote in her hand, her thumb resting lightly on the button. The basement’s usual scent of leather was undercut today by a faint, metallic tang of fear.
“The rules are simple,” Sarah said, her voice echoing slightly in the cavernous space. She guided a hesitant Emily backward until her knees hit the edge of the large plush bed. “You lie back and receive. He serves. If his attention wavers, if his technique becomes lazy…” She tapped the remote. “He gets reminded.”
Emily lowered herself onto the dark red duvet, her movements stiff. The black ribbon was still tied around her wrist, a little frayed now. She wore a simple silk robe, parted at the legs. Her eyes were wide, fixed on Mark who knelt on the concrete floor, shivering.
“Get over here,” Sarah commanded. Mark scrambled forward on his knees, the cage between his legs scraping lightly on the concrete. “Make her feel good. This is a privilege. Remember that.”
Mark leaned in, his breath brushing Emily’s inner thigh. He could smell her soap, a familiar lavender scent that now felt foreign, part of a different world. He glanced up at her face. She looked down at him, her expression unreadable—not cruel, not kind. Distant.
He pressed his mouth to her. His tongue slid through her folds, tasting her. She was dry at first, tense.
“He’s timid,” Sarah observed, her voice conversational. “Pathetic.”
A jolt of electricity shot through the collar. It wasn’t immense, but it was sharp, a sudden, vicious bite that locked his muscles and made him gasp against Emily’s skin. He jerked back.
“I didn’t say stop,” Sarah said softly. “That was for poor form. Now do it properly. Like you mean it. Like your worthless life depends on it. Because right now, it does.”
Mark dove back in, desperation overriding fear. He lapped at her fiercely, circling her clit, trying to summon wetness, a reaction. Emily inhaled sharply. Her legs relaxed slightly.
“Better,” Sarah purred, pacing slowly around the bed. “See, Emily? He just needs clear incentives.”
Mark worked his tongue, trying to find a rhythm he remembered from years ago, from a time when this was an act of love and not a test of survival. He sucked gently, then flicked rapidly. Emily’s hand came down and tangled in his thinning hair, not guiding, just gripping.
He found a sensitive spot and focused there. A soft moan escaped Emily. It was a genuine sound, one he hadn’t heard in years. It fueled him. He buried his face deeper, eating her with a frantic, focused intensity.
The shock hit him again.
This one was stronger. White light flashed behind his eyes. Every muscle seized. A strangled cry was muffled against her flesh.
“What? Why?” he gasped, pulling away, his whole body trembling.
“You were getting lost in it,” Sarah said with a cold smile. “Starting to enjoy yourself. This isn’t for your enjoyment, you stupid fuck. This is service. Keep your mind on your work. On her.”
Tears of frustration mixed with the wetness on his chin. He returned, now robotic, methodical. Lick, suck, repeat. He monitored his own reactions, trying to sterilize his own mind, to become just a tool. Emily’s breathing deepened again. Her grip on his hair tightened. She began to move her hips, just slightly, meeting his tongue.
“Good girl,” Sarah said to her sister, her voice warm with approval. “Take what you need from him. He’s yours to use.”
Emily’s movements became more urgent. The soft, wet sounds filled the room. Mark felt her swell, felt her thighs begin to quiver. He chased the building tension inside her, the ghost of a memory driving him.
Just as Emily’s body arched, a low groan building in her throat, Sarah pressed the button.
The shock was brutal. Mark screamed, his body convulsing violently, collapsing sideways onto the floor. He curled into a fetal position, twitching, saliva dripping from his mouth. The sharp, burned smell of the collar mixed with the basement’s other scents.
Emily cried out, her climax shredded, breaking into scattered, unsatisfied pulses. She pushed herself up on her elbows, her face flushed with anger and unmet need. “Sarah! Why then?”
Sarah looked down at Mark, writhing on the concrete. “Because the lesson isn’t just for him.” She walked to the bed and sat beside Emily, placing a comforting hand on her thigh. “It’s for you, too. Your pleasure isn’t tied to his performance. It’s tied to my permission. Do you understand?”
Emily stared at her sister. Then she looked at Mark, broken and weeping on the floor. The black ribbon on her wrist felt tight. She sucked in a shuddering breath, the last aftershocks of her interrupted orgasm fading into a hollow, aching throb.
“I understand,” Emily whispered.
“Good.” Sarah stood up. She toed Mark with her boot. “Get up. Clean yourself up. You’ve got laundry to do. And you,” she said, turning back to Emily, her voice shifting to a conspiratorial tone, “let’s have a glass of wine. You look like you could use it.”
Sarah helped Emily up from the bed, guiding her toward the stairs. Emily glanced back only once. Mark had managed to push himself to his hands and knees, head hanging low, strings of drool connecting him to the floor. He was a mess of tremors and silent tears.
At the foot of the stairs, Emily paused. “Shouldn’t we… take the collar off him?”
Sarah paused, her hand on the light switch. The single overhead bulb cast hard shadows. She looked at Emily, a slow smile spreading. “No,” she said, and her voice was final. “I don’t think we should.”
She flipped the switch, plunging the basement into darkness save for the faint, sinister glow of a single LED on the shock collar remote, which she placed deliberately on the kitchen counter upstairs. Mark was left in the perfect, suffocating black, the weight around his cock a constant, aching reminder. The only sound was his own ragged breathing, and the distant, laughter-tinged murmur of two women sharing a bottle of wine directly above his head.
The darkness was a physical thing, a pressure against his eyes and skin, making the throbbing in his groin and the sharp, residual ache from the shocks feel like the only real parts of him. Mark lay fetal on the cold concrete, the leather of the cock cage a familiar, humiliating grip, the weight of the shock collar a brutal reminder. Above, the murmur of voices and the clink of glass were a universe away.
Up in the clean, modern kitchen, the overhead lights were too bright. Emily sipped her Pinot Noir, the stem of the glass trembling slightly in her fingers. Sarah leaned against the granite island, watching her sister’s face, the remote between them like a third guest.
“You stopped him right when I was…” Emily began, then trailed off, staring into the ruby depth of her wine.
“Right when you were about to come?” Sarah finished, smiling. She took a slow, deliberate sip. “Yeah. That was the point. The orgasm he gives you is mine to grant, not his to earn. Feel that ache? That’s power, Em. It’s better than any climax he’s ever given you on his own.”
Emily shifted, the silk of her robe whispering. The hollow, frustrated throb between her legs was undeniable, a persistent emptiness that felt curiously potent. She thought of Mark’s desperate, fearful tongue, the way his body had jerked and spasmed under her.
“He was so… broken at the end,” she said, her voice quiet.
“He was perfect at the end,” Sarah corrected. “Finally. A useful object.” She traced the rim of her glass. “The collar was a good idea, but it’s a blunt instrument. There are more subtle ways to break someone, to make them truly pliable.”
Sarah let the silence hang, watching the curiosity war with something darker in Emily’s eyes. The distant, almost inaudible sound of a sob from the ventilation grate was a perfect soundtrack.
“I was thinking,” Sarah said, leaning forward, her voice a conspiratorial drop. “Mark’s service shouldn’t be limited to you. That’s still thinking small. The ultimate act of submission, of ownership, isn’t about eating pussy. Any devoted dog can be trained to do that.” She paused, letting the implication sink into the warm, wine-softened air. “It’s about making him degrade himself completely. To use his mouth on command for anyone. To be a tool for anyone we choose.”
Emily’s breath hitched. She set her glass down, the click too loud in the quiet kitchen.
“You mean…”
“I mean having him kneel for Nathan. Having him take that thick, uncut cock in his mouth and suck it until Nathan comes down his throat.” Sarah’s words were deliberate, graphic, and utterly devoid of sentiment. “To make him fluff another man, get him hard and ready, just because we told him to. Imagine the look on his face. Imagine the sound he’ll make.”
The image crashed into Emily’s mind, vivid and shocking: Mark on his knees, Nathan’s work-roughened hands fisted in his thinning hair, the stark contrast of their bodies. Her husband’s terrified, obedient mouth. It was disgusting. It was monstrous.
It made the hollow ache between her legs clench with a sudden, searing heat.
She didn’t speak. She couldn’t. She just stared at Sarah, her lips parted, a flush creeping up her chest.
Sarah saw the intrigue win, saw the flicker of dark, possessive fascination in her sister’s eyes. She picked up the remote from the counter, her thumb stroking its smooth surface. The single LED winked in the kitchen light.
“Think about it,” Sarah said softly, finally. “The power isn’t just in making him serve you. It’s in knowing he’ll serve anyone. That he’s that fucking owned.” She pushed the remote toward Emily. “Here. You hold onto this tonight. Just in case he needs a reminder down there in the dark of who he is now.”
Emily’s hand closed around the plastic. It was still warm from Sarah’s grip. The laughter from earlier was gone, replaced by a heavy, resonant silence, pulsing with the shape of a new, terrible possibility. The faint, metallic scent of the basement seemed to rise through the floorboards and curl around the two of them, binding them together in the quiet, well-lit kitchen.
