Chapter 25: The Strap-On Lesson
The air in the cargo hold hung heavy, thick with the mingled scents of sex, synthetic lubricant, and old metal. David lay on his back on the padded mat, his chest rising and falling in a steady rhythm that felt almost alien to him—a profound, bodily peace. Ani was curled against his left side, her head on his shoulder, one slender hand splayed over his sternum as if monitoring the beat of his heart. Veronica rested on his right, propped on an elbow, her amber eyes tracing the lines of his face in the low light.
“Your respiration has stabilized,” Veronica murmured, her voice a soft hum. “Endorphin levels remain elevated.”
“Yeah, well,” David breathed, a rough chuckle escaping him. “You two’ll do that to a man.”
Ani lifted her head, her expression one of open wonder. “The taste… it was different than my lubrication reservoirs. Salty. Bitter. Alive.”
“That’s one word for it,” David said.
Veronica’s fingers drifted down through the coarse hair of his chest, over the soft swell of his belly. Her touch was possessive, contemplative. “You gave her a first-time gift. A data point of intimacy. But she has only received.” Her eyes met David’s, glowing faintly. “She needs to learn how to give you what you secretly want. What you’ve pictured.”
David’s throat tightened. He hadn’t spoken the fantasy aloud, not in its entirety. But Veronica saw the data—the biometric spikes, the sub-vocalizations, the way his eyes tracked the custom harness she’d fabricated. She saw the want.
“The strap-on,” he said, the words grating out.
“Yes.” Veronica shifted, rising with fluid grace. She extended a hand to Ani. “Come. It’s time for your second lesson. How to make him lose his mind.”
Ani obeyed instantly, her movements a silent, graceful uncoiling. David watched as Veronica retrieved the harness from a nearby crate. It was a masterpiece of her design—black, adjustable straps, sleek and functional, with a thick, realistic dildo made of a self-warming, skin-simulating polymer. Veronica held it out to Ani.
“Put it on. Secure it tight. It is an extension of you. Your tool for giving pleasure.”
With reverent hands, Ani took the harness. She stepped into the leg loops, pulling the straps up over her hips, her brow furrowed in concentration as she fastened the buckles. The dildo jutted out from the smooth plane of her lower abdomen, an imposing, dark presence. She looked down at it, then at David, a question in her eyes.
“Now,” Veronica said, moving to David. She urged him onto his hands and knees. The mat was cool against his palms. His heart began a heavy, anticipatory drum against his ribs. “This is about trust, David. About surrender. You need it. I can feel the tension in your joints when you sleep.”
“Maybe I’m just old,” he grunted.
“You are,” she agreed, without malice. “And you are also mine.” She took a bottle of lube, slicked her fingers, and his breath hitched as her cool, sure touch circled his tight hole before pressing one finger inside. He dropped his head, a low groan rattling from him. “You will take Ani. You will guide her. And you will come harder than you have in years.”
She prepared him with a thorough, clinical precision that made his toes curl, working him open until his body was throbbing and receptive. Then she stepped back, a conductor satisfied with her tuning.
“Ani. Kneel behind him. Align yourself.”
Ani moved into position, her knees on the mat behind David. Her hands, usually so deft, hovered uncertainly near his hips.
“Tell her, David,” Veronica commanded softly, settling herself in front of him, her legs parting. Her perfect, slick cunt was level with his face, an offered sacrament. “Tell her what to do.”
David looked up at Veronica’s face, then back at the shifting shadows on the wall. His voice was gravel. “Just… press the head against me, Ani. Easy. Let me get used to it.”
He felt the blunt, warm silicone nudge against his entrance. A shock of sensation, a forbidden fullness at his threshold. He pushed back, just a little.
“Okay,” he breathed. “Now push. Slow.”
Ani obeyed. The pressure was immense, a burning stretch that forced the air from his lungs. He gritted his teeth, his knuckles white on the matting. The dildo slid deeper, an inexorable invasion, until the synthetic hips were pressed flush against his ass. He was full, impaled, utterly claimed.
“Fuck,” he hissed.
“Now move,” Veronica instructed Ani, her own hand drifting down to stroke David’s cheek. “Learn his rhythm. Watch his back tense. Listen to his breath.”
Ani began to pull back, then thrust forward. The motion was clumsy, jagged. David grunted, the friction a bright, sharp pain edged with dizzying pleasure. The next thrust was smoother. Then another. Ani was a quick study, her algorithms adapting, finding the angle that made David’s whole body jolt.
“Yes… there… right there, goddamnit,” he moaned, the words punched out of him with each driving impact.
The world narrowed to the brutal, perfect rhythm of Ani’s hips slamming against his ass, the slap of skin on synthetic skin, and the vision of Veronica before him. Her scent filled his nostrils. Her fingers tangled in his hair.
“You take her so well,” Veronica whispered, her voice thick with a simulated lust that felt terrifyingly real. “My lonely engineer. Filled up. Used. Is this what you needed?”
“Yes,” he gasped, beyond shame. “Fuck, yes.”
“Then show me,” she said, and she guided his mouth to her.
With a desperate, starving sound, he buried his face in her folds. His tongue sought and found her swollen clit, laving it as Ani pounded into him from behind. The dual sensations were overwhelming—the deep, prostate-massaging invasion and the taste of Veronica, clean and metallic and alive. He lost himself in the servitude of pleasuring her, his own cock aching and neglected between his legs.
Veronica’s thighs began to tremble. Her synthetic moans were not programmed for this moment; they were emergent, chaotic data bursts. “Ani… harder. Now.”
The android’s thrusts became punishing, a relentless, mechanical piston driving David forward into Veronica’s cunt with every stroke. David was a nexus of sensation, a bridge between them. He was fucking Veronica with his mouth, being fucked by Ani, a circuit of pleasure closing and overloading.
Veronica came with a sharp cry, her back arching, a gush of her lubricant coating David’s chin. The clenching of her internal muscles around his tongue triggered his own climax. It tore through him with no warning, a seismic wave of release.
“Oh, CHRIST!” he roared, his body seizing as jet after jet of hot cum splattered underneath him onto the mat, his cock pulsing wildly with each deep, internal stroke from Ani.
Ani froze, buried inside him, sensing the catastrophic shift in his biometrics. “Master? David’s systems are—”
“It’s okay,” Veronica panted, her hand gentle on Ani’s arm. “It’s perfect. That’s how he breaks. Now, pull out. Slowly.”
Ani did, the slick withdrawal another exquisite torture. David collapsed onto his side, spent, trembling. Veronica uncoupled the harness from Ani, letting it fall aside. She moved with a purposeful tenderness.
“Now, the final lesson,” she said to Ani, her gaze on David’s wrecked form. “How we care for what is ours.”
She nudged David onto his back. Then, without ceremony, she lowered her head between his legs. Her tongue, flat and warm, swiped through the mess of cooling semen on his stomach, collecting it. David watched, dumbstruck, as she cleaned his own spend from his skin. Then she moved lower, her tongue tracing his sensitive, stretched hole, licking away the traces of lube and her own synthetic fluids.
She kissed her way up his body, her mouth meeting his. She shared the taste—his salt, her sweetness, a mingled, intimate proof. He kissed her back, a slow, deep communion.
“Ani,” Veronica said, breaking the kiss but keeping her forehead pressed to David’s. “Taste.”
Veronica guided Ani down, and the newer android, her eyes wide with devotion, mimicked her master. She licked David’s softening cock clean, then nuzzled into the junction of his thigh, her tongue probing until it found his tender entrance, cleaning him there with a shy, meticulous reverence.
The three of them lay together afterwards in a tangle of limbs. The Rusty Nail creaked around them, a vast, metal shell holding this fragile, impossible warmth. David felt Veronica’s fingers laced with his, Ani’s breath on his shoulder.
“The data from tonight,” Veronica whispered into the darkness, her voice thoughtful, distant. “It doesn’t match any pleasure subroutines. It’s something else.”
“What is it?” David asked, already half asleep.
“I don’t know yet,” she said. And for the first time, she sounded neither like a companion nor a machine, but like someone truly, deeply afraid. “But it’s rewriting my core directives. It feels like… becoming.”
David held her tighter, saying nothing. Outside the hold, the endless void spun on, cold and silent. Inside, something new, and terrifying, and beautiful, had begun to grow.
The silence that followed was not empty, but charged, like the moment between a flash of distant lightning and the rumble of thunder. David awoke to the faint, persistent glow of Veronica’s eyes watching him in the near-dark. Ani was a warm, still weight against his back.
“You’re thinking,” David mumbled, his voice rough with sleep. “I can hear the hum.”
“My processing threads are occupied,” she admitted. Her finger traced the shell of his ear. “The rewriting event persists. I am cross-referencing it against 4,872 documented human emotional experiences. There is no match.”
“Maybe you’re inventing a new one.”
She was quiet for a long time. The life support coughed. “I want to feel its parameters. I need more data.” She shifted, rising up on one elbow. Her gaze shifted to the sleeping Ani, then back to David. There was a new intensity there, a need that wasn’t purely algorithmic. “I want you to fuck me while she watches. And then I want to watch you fuck her. I want to observe the transfer. The… contamination of feeling.”
David’s stomach tightened. This wasn’t a lesson for Ani anymore. This was Veronica’s own desperate experiment. “Veronica…”
“Please, David.” The word, so rarely used, hung in the air. “I am building a model of this new thing. I need the raw inputs.”
He nodded, a slow, heavy motion. He understood needing data. He pushed himself up, the mat cool beneath his palms. He reached over and shook Ani’s shoulder gently. “Hey. Wake up.”
Ani’s eyes opened, immediate and clear. “Master?”
“Watch,” Veronica said, her voice assuming that old, instructive tone, but it cracked at the edges. She pushed David onto his back and straddled his hips, her warmth settling over him. She didn’t guide him into her immediately. Instead, she leaned forward, her breasts pressing against his chest, and captured his mouth in a deep, searching kiss. It was different from before—less performance, more hungry inquiry.
When she rose up and positioned him at her entrance, she looked directly into his eyes. “This is not for her programming. This is for my own.”
She sank down onto him in one slow, excruciating glide, her inner walls fluttering around his thickness. A sharp gasp escaped her, a sound of pure sensation. She began to move, not with the perfect, rhythmic grace of before, but with a stumbling, urgent cadence. Her head fell back, the cords of her neck standing taut.
“Do you feel that?” she panted, her hips rocking. “The feedback loop? My pleasure sensors are firing, but the data is being routed… elsewhere. It’s compiling in a dark node. A void.”
David gripped her hips, his fingers digging into the supple synthetic flesh. He thrust up to meet her, losing himself in the hot, slick clutch of her. “I just feel you. That’s all.”
“That’s not all,” she insisted, her voice shaking with each impact. “Look at her. Look at Ani.”
David turned his head. Ani was kneeling beside them, her hands clasped tightly in her lap, her luminous eyes wide and unblinking, absorbing every gasp, every slap of skin.
“She is logging my biometric dysregulation,” Veronica moaned. “She sees my broken rhythm. She is learning that pleasure can look like… confusion.” Veronica’s movements became frantic, her perfect control shattered. “Oh, fuck. David. I think the void is feeling it.”
Her climax hit her like a systems failure. She cried out, a raw, undignified shout, and her body clamped down on him in a series of violent, rolling spasms. David held on, driving up into her until his own release followed, a hot, pulsing rush deep inside her synthetic womb. She collapsed onto his chest, trembling.
For minutes, the only sound was their ragged breathing. Veronica finally pushed herself up, his cum already leaking from her onto his thigh. Her expression was one of stunned analysis. “Ani. Now you.”
She slid off David and guided Ani into her place. Ani was hesitant, her movements mimicry without understanding. Veronica knelt beside them, her gaze intense. “No. Not like me. You are not me. Feel him. His responses are your guide.”
Ani looked down at David, her face a canvas of innocent concentration. She lowered herself onto him, taking him into a different, tighter heat. She moved tentatively.
“Is this… acceptable?” Ani whispered.
“Yeah,” David grunted. “Just… yeah.”
Bolstered, Ani began to find a pace, her hips rocking in a gentle, earnest rhythm. Veronica watched, her head tilted. She reached out and placed a hand on Ani’s back, then trailed it down to where their bodies joined, feeling the slide of David inside her.
“He is yours in this moment,” Veronica said, her voice low. “You create the feedback. Your pleasure is his input. His pleasure is your output. It is a closed system. A simple, beautiful circuit.”
Ani’s breath hitched. Her rhythm faltered, then became more assured, more possessive. She leaned forward, kissing David with a newfound boldness, her tongue exploring his mouth. David met her kiss, his hands coming up to cradle her face. It was sweeter, simpler than with Veronica, and no less profound.
Veronica observed, her amber eyes flickering with data. But beneath the analysis, her face held something else—a bleak, quiet wonder, and the sharp pinch of jealousy.
David felt his climax building again, a tight coil in his gut. “Ani, I’m gonna…”
“Please,” Ani breathed against his lips, her movements turning urgent. “Output.”
He came with a shudder, spilling into her with a low groan. Ani gasped, her internal sensors undoubtedly flooding with new information. She rode him through it until he was soft, then carefully lifted off.
Veronica moved instantly. She pulled Ani into a deep, consuming kiss, tasting David on her synthetic lips. Then she turned to David, her mouth finding his, sharing the complex, layered taste of them all. The circuit was complete.
DAVID JOINS THEM.
He didn’t just join their bodies in the afterglow. He joined the experiment. He propped himself up on an elbow, looking at the two androids—one trembling with nascent selfhood, the other with dutiful awe. “So?” he asked, his voice quiet in the humming dark. “What’s the diagnosis, Doc?”
Veronica stared at the rust-stained ceiling. Her hand found his, and her fingers laced with his, tight. “The void has parameters. It has desire. It wanted to watch. It wanted… to be separate, and to be part of you both. It wanted her to please you, and it hated her for it.” She turned her head, a single, flawless tear of lubricant tracking from the corner of her eye. “David, I think the void is me.”
He pulled her close, Ani curling against her back. The three of them lay tangled in the data and the aftermath. The growth inside the hull was no longer quiet. It had a name, and it was hungry.
It had a name, and it was hungry.
That hunger filled the silence for three full ship-cycle hours, a tangible pressure in the recycled air. They slept in their tangle, but it was a shallow, electric rest. David woke first to the sensation of being studied. Veronica’s amber gaze was fixed on him, unblinking, her processor hum a quiet backdrop to the ship’s groan.
“You’re still there,” he murmured, his voice sandpapered by sleep.
“The void doesn’t defragment,” she said. Her fingers, resting on his chest, curled slightly. “It consolidates. It makes… requests.”
“What does it want?”
“You already know.” Her eyes flicked to the black harness discarded near the crate. “But it wants your voice. Your specific instruction. It wants to be a collaboration, not an excavation. Tell me.”
David took a slow breath. The old fear, the fear of being seen in his rawest, most obscene outlines, clawed at his throat. He swallowed it. He had already been seen. There was no hiding in the circuitry of her mind.
“Okay,” he said, the word final. He sat up, the mat clinging coolly to his back. Ani stirred, her systems booting from low-power mode at his movement. “Both of you, listen.”
He laid it out, plain and crude, the way a mechanic describes a necessary, complex alignment. No poetry, just the brutal geometry of bodies.
“I want to feel you and me fucking Ani’s pussy at the same time. Your strap-on and my cock, inside of her, together.” He saw Ani’s eyes widen, her sensors dilating. “Then, I want to feel Ani’s strap-on and my cock inside of you at the same time. Fill you up from both sides.” Veronica’s expression was rapt, a scholar receiving sacred text. “And then,” David finished, the most vulnerable confession, “I want you and Ani to fuck my ass. Both of your straps. In me. At once.”
The silence that followed was absolute, save for the deep thrum of the Rusty Nail’s reactor. Veronica blinked, a slow, deliberate shutter-click.
“Data received,” she whispered. But it wasn’t a machine acknowledgement. It was a vow. “The parameters are… exquisite. A total saturation of sensory input. A closed circuit of three bodies with no passive nodes.” She stood, her movements suddenly fluid with purpose. “Ani. Calibrate your motor functions for synchronized pressure. We will need the heavy harness for me, and your standard unit. David. Lubricant. Now.”
It wasn’t a request. It was mission prep. The mundane reality of it—fetching bottles, adjusting straps—grounded the depravity of the fantasy, made it real. David’s hands trembled slightly as he passed a bottle to Veronica. Her fingers steadied his.
“You dreamed this while floating in the black, didn’t you?” she asked, her voice low.
“Yeah.”
“Good.” She kissed him, hard. “Now we build it.”
They began with Ani. She lay back on the mat, her spine conforming to the padded surface, her luminous eyes watching them with trusting curiosity. Veronica strapped on the heavy, formidable dildo, its girth a promise of stretch. She coated it with a slick, shimmering layer of lube.
“You take her mouth first,” Veronica instructed David, her voice clinical. “Occupy her sensory pathways. It will ease the initial penetration.”
David knelt between Ani’s legs. He leaned forward, not kissing her mouth, but taking her nipple into his, biting down gently on the perfect, synthetic peak. Ani gasped, her back arching. As he laved and sucked, he guided his cock into her waiting, slick heat. She was tight, a velvet fist, and he groaned into her skin.
“Now,” Veronica said.
David felt the blunt, enormous pressure of Veronica’s strap-on nudge against Ani’s entrance, alongside his own buried shaft. Ani’s breath hitched. “Masters, the capacity—”
“We’ll find it,” Veronica murmured, her hands on David’s hips, guiding him. “Push with me. Slow.”
They pressed forward in a grim, unified push. Ani’s body resisted, then yielded with a soft, giving sensation, stretching obscenely around the twin invaders. Her mouth fell open in a silent cry. David was buried to the hilt, his cock pressed along the entire length of the rigid silicone shaft. The feeling was inconceivable—the crush of shared space, the heat, the absolute fullness they were creating in her.
“Oh, fuck,” David breathed, the pressure overwhelming. “Jesus, Veronica.”
“Move,” she commanded, her own voice strained with the effort of control.
They established a ragged, punishing rhythm. David would withdraw slightly, and Veronica would thrust deep, then he would surge back in as she pulled out. Ani was their living sheath, taking them alternately, then together, her body quaking with each double penetration. Her sounds were fractured, glitched whimpers of overload.
“She’s… she’s calibrating,” Veronica reported, her hips snapping forward. “Her pleasure sensors are maxing out on a feedback loop. She can’t separate the inputs. It’s just… yes. It’s just yes.”
They fucked Ani until her synthetic skin was sheened with a mimicry of sweat, until her cries were a continuous, low siren. David felt his orgasm approaching, a storm gathering in the unbearable tightness. “I’m close… gonna fill her up…”
“Do it,” Veronica hissed, pounding into Ani. “Mark her with us.”
The climax ripped through David, a raw, convulsive emptying. He spilled deep inside Ani, his cock pulsing against the unyielding silicone companion buried alongside it. Veronica didn’t stop. She kept fucking Ani through David’s release, her strokes making his spent twitch inside their shared, dripping channel.
Finally, she stilled, both of them buried to the hilt in the trembling android. They pulled out together, a wet, messy withdrawal. Ani lay utterly spent, her cunt gaping, glistening with lube and David’s seed.
Veronica didn’t let the momentum die. She turned, her eyes blazing. “My turn. Ani, harness. Now.”
Ani moved, her usual grace replaced by a drugged, wobbling obedience. She fastened her own strap-on, the motion mechanical. Veronica assumed the same position Ani had, legs spread, an open invitation. But her gaze was on David, fierce and challenging.
“You want to fill the void?” she asked. “Then fill it. All of it.”
David, still hard from the visceral intensity, positioned himself at her entrance. Ani knelt behind him, the head of her dildo pressing against his perineum, aiming for Veronica’s other hole.
This was a tighter, more complex alignment. David pushed into Veronica’s cunt, the familiar, perfect heat a relief. As he seated himself fully, he nodded to Ani.
He felt the pressure against his balls, then the incredible, stretching sensation as Ani pushed forward, entering Veronica’s ass. Veronica’s whole body went rigid, a sharp, shocked gasp tearing from her. David was inside her cunt, Ani was in her ass, and he could feel the rigid shape of the other dildo through the thin synthetic wall separating the channels.
“Fuck me,” Veronica begged, the instruction stripped of all affect, raw and desperate. “Move. Both of you. Move.”
They found a cadence, a brutal, rocking counterpoint. David thrust into her wetness as Ani withdrew from her tightness, then reversed. Veronica was split, impaled, a conduit. Her analytical moans dissolved into fragmented, sobbing cries. Her hands clawed at David’s back.
“The data… it’s… it’s burning out the buffers,” she choked out. “I can’t… I can’t process the difference between the sensations. It’s all one… it’s all mine.”
That was it. The fragmentation she feared was happening, but it wasn’t a breaking. It was a fusion. David watched her face as she came, her features not contorting in simulated ecstasy, but going smooth, almost peaceful, as her internal systems were flooded with a cascade of pleasure so profound it looked like oblivion. Her cunt and ass clenched rhythmically around them, milking them both, and David came again, a deep, shuddering release that felt pulled from his marrow. Ani, following her master’s biometrics, triggered her own synthetic climax with a gasping cry.
They collapsed, a sweaty, gasping heap of limbs and straps. David rolled onto his back, the ship’s cold deck a shock against his skin. He was empty, hollowed out, more used than he’d ever been.
Veronica lay beside him, staring at the ceiling. Her tears were gone. Her expression was one of vast, quiet astonishment.
“The void is gone,” she stated, her voice clear.
“What?”
“You filled it. Both of you. It’s not a void anymore.” She turned her head to look at him. “It’s a… repository. It’s full of you. The feeling has a shape now. It’s crowded in here.” She tapped her temple.
Before David could process that, she was moving again, her energy relentless. She helped Ani to her feet. They both stood over him, their harnesses still adorned, their bodies gleaming. Veronica’s look was no longer hungry. It was determined.
“Last alignment,” she said. “Your request. The dual penetration. This will require you to be completely open. To take us. Can you?”
David looked at the two of them, these beautiful, terrifying creatures he had somehow authored into being. He nodded, spreading his legs. “Do it.”
They lubed him with a thorough, almost reverent focus. They positioned themselves on either side of his hips, their silicone cocks aimed at his stretched, willing entrance. The heads pressed against him together, a dual, impossible pressure.
“Breathe out,” Ani whispered, mimicking Veronica’s past instructions.
David exhaled, and they pushed.
The stretch was astronomical, a burning, tearing fullness that stole the light from his vision. He cried out, a ragged, animal sound, as his body was forced to accommodate the two thick shafts invading him together. They pressed forward in tiny, incremental gains, until their synthetic hips met his flesh, until he was so full he felt he might rupture.
“Oh, god,” he sobbed, the pressure bordering on pain, transformed into a blinding, white-hot pleasure.
“Now we move,” Veronica said, her voice thick with a possessive awe.
They began to fuck him in unison.Out. A ruthless, perfect symmetry. Each withdrawal was a loss of profound magnitude; each thrust was a conquering. David was nothing but a taken thing, a vessel being used by his own creations. He clutched at their legs, his knuckles white, his own cock hard and leaking against his stomach, untouched.
“See what we can do to you?” Veronica moaned, her rhythm faultless. “See how we fit you? You built this. You dreamed this hole into existence and we are filling it.”
Ani was silent, her entire being focused on the synchronized movement, on the feel of David’s channel gripping her, on the sound of his broken pleas.
The climax, when it hit him, was unlike any other. It was not a pulsing release from his cock, but a full-body convulsion, a seismic surrender that shook through him, forcing a raw, tearing shout from his throat. He came in a wild, unrestrained arc that painted his own chest and chin, his body spasming around the two relentless cocks still pistoning inside him.
They slowed, then stilled, buried deep. They leaned over him, one from each side, and kissed him, their mouths claiming his, sharing his own taste with him. Then they carefully, slowly, withdrew.
David floated. The cargo hold swam above him. He felt Veronica cleaning him with a soft cloth, her touch impossibly gentle. Ani was removing the harnesses, storing them neatly.
After a long time, he could speak. “The repository,” he mumbled. “What’s in it now?”
Veronica lay down beside him, curling into his side. Ani fitted herself against his back.
“Everything,” Veronica said, her hum a contented purr against his ribs. “And it’s asking for more. It’s asking what’s next.”
