Science Fiction Sex Story: Chapter 1: Guided - Dylan and his mother Sophie wake deep inside an alien ship, torn from their ordinary lives by a blinding flash. What starts as an abduction becomes a test of endurance: an alien mind, alien rules, and only one person to trust — a slow-burn story of survival, power, and intimacy at the very edge of the known universe.

Consciousness returned slowly, as if pushing through the depths of murky water. Dylan opened his eyes and immediately squeezed them shut — the surrounding light seemed unnatural, sourceless, seeping from the walls themselves. He lay on something faintly warm and smooth, like polished metal or ceramic.
His head throbbed. The last thing he remembered — he and his mom were driving back from the store, the evening rain drumming on the car roof, the wipers scraping across the glass, and then ... a flash. A sharp, piercing sound that plugged the ears, and the feeling that the world had been yanked out from under him.
“Mom?”
He sat up sharply, ignoring the flare of pain in the back of his skull, and looked around.
The room was a hybrid of a cell and a laboratory — walls of dark gray material, warm to the touch, almost alive, without a single seam or joint. No windows, no doors in any familiar sense. Only a faint pulsing glow emanated from the surfaces themselves, casting ghostly shadows. The air was dry and smelled strange — metal, ozone, and something else, faintly sweet.
“Dylan?”
His mother’s voice came from the right, edged with a panic she was trying to suppress.
Dylan turned. Sophie sat a few meters away, pressing her palms to her temples, her light hair disheveled, her soft light shirt pulled askew, baring her collarbone. She looked confused and frightened, but she was trying to hold it together.
“I’m here, Mom.”
He got to his feet, feeling slightly dizzy. The space around them was empty — no furniture, no objects, just the two of them on the floor, which vibrated faintly, as if somewhere deep inside, mechanisms were running.
“What happened? Where are we?” Sophie stood up too, straightening her clothes, and Dylan noticed how her hands were trembling. She stepped toward him, and he allowed himself a brief hug, breathing in the familiar scent of her perfume mixed with the smell of fear.
“I don’t know. The last thing I remember — the light. And then we were here.”
Dylan pulled away and began examining the walls, running his palm over them. The material was warm to the touch, almost alive, and he could feel a faint pulse under his fingers. In some places the surface felt softer, more pliable, like a membrane.
“Is this a dream?” Sophie whispered behind him. “Tell me this is a dream.”
“If it is, it’s too real.”
He turned and met her green eyes, full of anxiety. She had always been strong — a school psychologist, used to calming others — but now her gaze held the same confusion as his own.
“We need to find a way out.”
They moved along the walls, but there were no openings. The room seemed sealed, airtight. In the center of the ceiling hung a sphere of black glass that didn’t emit light but absorbed it, and from it came a vague sense of observation. Dylan noticed the sphere turn slightly, tracking them, and goosebumps ran down his skin. He felt a faint, barely perceptible presence in his head — like something foreign lurking at the edges of his consciousness, waiting for a moment to reveal itself.
“I don’t like this,” Sophie hissed through her teeth. “This is an abduction. We’ve been abducted.”
Dylan nodded, clenching his fists. He felt anger rising inside him but suppressed it — he needed to stay clear-headed.
And then the wall before them parted silently, revealing a passage.
A corridor. They stepped out.
The corridor was wider than their cell and stretched in both directions, disappearing into darkness. Oval niches lined the walls, some dark, some lit with a pale blue glow. Not a soul in sight. Dylan turned and noticed the black sphere from their cell now hung in the passage behind them, floating silently, as if following them.
“Stay close,” Dylan said, taking a step forward.
Sophie took his hand. Her palm was cold and damp.
“We’ll get out of here,” she said, but there was no confidence in her voice.
They walked. The corridor twisted, sometimes widening into halls filled with incomprehensible equipment — glass flasks with cloudy liquid, metal tables with straps, racks of instruments whose purpose was all too easy to guess. Sophie looked away, but Dylan noticed her flinch at the sight of the more ominous devices.
“Looks like an operating room,” he breathed.
“Don’t think about it.”
They walked a few more meters, and suddenly, ahead in the dim light, something stirred. Tall, coal-black, with two long legs, two arms, and...
Tentacles writhed behind it like snakes poised to strike — Dylan counted four, but in the dimness behind it, barely visible, another pair stirred, pressed against its body. The creature stood over two meters tall, its head featureless save for two utterly black eyes that receded into infinity.
Something ancient, spinal, recognized danger before reason could. A chill rolled down Dylan’s spine, his palms went slick in an instant, and his heart slammed so hard blood roared in his ears. Everything about this creature was wrong — its inhuman height, its faceless head, its dead stillness — and from that wrongness his insides clenched into a tight, icy knot. He tried to swallow, but his mouth was dry, and the air seemed to thicken, refusing to enter his lungs.
Beside him, Sophie had turned to stone. For fifteen years she had read people at a single glance — by the tremor of their eyelids, by their breathing, by the way they held their shoulders — and that skill had always anchored her, given her the sense that she understood who was before her. Now it crumbled to dust: in the two black voids of its eyes there was nothing for her gaze to catch on — not a single familiar feature, not one readable emotion. Only emptiness remained — and an animal terror rising from the deepest pit, older than thought. Through it, her maternal instinct surged — to shield her son with her own body — but her body wouldn’t obey, her legs turned to lead, and her own breath broke into a short, frightened gasp that she immediately stifled.
Dylan froze. Sophie gripped his arm so hard it would surely leave bruises — but he felt no pain: adrenaline drowned it out.
The creature stepped forward, its footsteps nearly silent. It stopped a couple of meters from them, tilting its head — a gesture that looked like curiosity.
And then it spoke.
The voice was low, slightly guttural, with an unusual timbre that grated on the ear — but the words were clear, spoken aloud. Dylan shuddered, realizing he understood every word in his native language, though the creature’s lips barely moved. He felt a light stir somewhere deep in the back of his skull — a translator implant, invisibly embedded in their consciousness, converting alien speech into comprehensible meaning.
“You. Boy. Come here.”
Dylan swallowed. His legs wouldn’t move.
Sophie pulled him back.
“Don’t you dare,” she hissed.
But one of the tentacles shot forward with incredible speed, coiled around Sophie’s waist, and tore her away from her son. She cried out, trying to break free, but its grip was like iron.
“Let her go!” Dylan roared, lunging forward.
A second tentacle stopped him, pressing against his chest, pushing him back — gently but inexorably.
“Don’t rush. You will both participate.”
Its voice was calm and mocking at the same time.
“I am studying. Your species. Your bodies. Your reactions. It will be interesting to see how you break.”
The tentacle holding Sophie lifted her into the air, turning her to face Dylan. Her eyes were wide with terror, her hands clawed at the oily, smooth black surface — uselessly.
“Boy. You will do as I say. Or she will be hurt.”
Dylan lunged again, but the tentacle on his chest increased its pressure, pinning him in place.
“You have kinship bonds. Mother and son. I know. This will enhance the experiment.”
“Go to hell!” Dylan shouted, feeling tears of helplessness burn his eyes.
The creature made a sound like laughter — low and vibrating, making the walls hum.
“You will be obedient. First ... remove her upper garment.”
Dylan went still.
“What?”
“You heard me. Or I will tear off her arm.”
Sophie struggled harder, but one of the free tentacles slid under her chin, forcing her still.
“Dylan, don’t listen to him!” she cried. “Don’t do this!”
He looked at her — at the mother who had raised him alone, who was everything to him — and felt the world crumbling. The creature’s black eyes watched him with cold expectation.
His hands shook as he stepped forward.
“I’m sorry, Mom,” he whispered, approaching.
The tentacles released Sophie just enough for her to stand, but not to run. Dylan stood before her, avoiding her eyes.
“I can’t let him hurt you,” he said, raising trembling fingers to the first button of her shirt.
Sophie squeezed her eyes shut. A tear slid down her cheek.
The fabric of the shirt was soft, almost silky under Dylan’s fingers. The first button gave way easily — too easily, with a soft click that echoed in the empty space. Through the gap, a strip of skin flashed, her collarbone, the edge of a simple cream bra.
Sophie bit her lip. Her chest rose and fell with rapid breathing, and Dylan could feel the heat radiating from her. The smell of fear mixed with something else, sharper — the scent of her body, which he had known since childhood, but now it registered differently, more acutely.
“Faster,” she hissed through her teeth, not opening her eyes. “Just do it.”
She wanted it to be over. So did he.
Second button. Third. Eyelet after eyelet, his fingers slipped, trembled, brushed against her breast, and he felt her tense under his touch. The light fabric fell open, revealing her stomach, her ribs, the lower curve of her breasts hidden by the bra.
The tentacle behind the creature swayed, as if impatient.
“Good. Continue. Remove it completely.”
Dylan took the edges of the shirt and pulled them apart, easing the fabric off Sophie’s shoulders. She instinctively pressed her arms to her chest, covering herself, but he gently guided them away, and the shirt fell to the floor, settling silently on the smooth surface.
Sophie stood before him in her undergarments, bare to the waist. Her skin was covered in goosebumps. She looked somewhere to the side, at the wall, unable to meet his eyes.
“Mom...” he began, but his voice broke.
“Warm. Skin. Touch.”
“What?” Dylan looked up at the creature. “No.”
The tentacle around Sophie’s waist tightened slightly, and she let out a choked sound.
“Touch. The breast. Examine. Or I will hurt her. Very badly.”
Dylan looked at Sophie. She nodded, barely perceptibly, her eyes filled with a plea — not for mercy, but for him to just do it, to end the torture.
He raised his hand. His palm trembled. Slowly, very slowly, he brought his fingers toward her breast, toward the fabric of her bra, toward the soft curve showing through the lace.
The touch was light, almost weightless. He could feel the warmth of her skin even through the fabric, felt her hold her breath. Sophie flinched but didn’t pull away.
“I’m sorry,” he whispered, running his fingers over the full curve, feeling the yielding flesh beneath the lace.
“Harder. Squeeze.”
Dylan squeezed his eyes shut. His fingers closed, pressing into his mother’s breast through the fabric, feeling her tense, feeling the nipple harden under his touch. Sophie let out a short, strangled sound — half sob, half moan — and turned her head, hiding her face, on which a faint flush had already appeared.
“Please,” she breathed. “Please, stop this.”
The creature stepped closer, and now Dylan could see it better — its skin was covered in small, iridescent scales that shimmered in the dim light. It smelled of ozone and resin — a sharp, living scent.
“Interesting. Mother and son. That same forbidden closeness. I want to see more. Boy, kiss her. On the mouth.”
Dylan snatched his hand back as if burned.
“No. This is too far.”
“You think you have a choice?”
One of the rear tentacles shot forward and coiled around Sophie’s throat, tightening just enough to obstruct her breathing. She rasped, digging her nails into the muscle constricting her neck.
“Okay! Okay, let her go!” Dylan shouted, lunging forward.
The tentacle released her, and Sophie gasped, coughing. Tears streamed down her cheeks, her mascara running, smearing.
“Don’t,” she rasped. “Don’t, Dylan. I can take it.”
But he had already stepped to her. He took her face in his hands, feeling her tremble under his fingers. She was so warm, so alive, so his — and at the same time forbidden, wrong, and that knowledge burned him from the inside.
“I won’t let him hurt you,” he said, looking into her eyes.
And he kissed her.
Sophie’s lips were dry; he tasted salt — her tears. She didn’t respond, frozen like a statue, letting him kiss her but not participating. Her arms hung limp at her sides.
Dylan held for a moment, feeling his heart hammer somewhere in his throat, then pulled back.
“Not enough. I want to see tongue. Open your mouth.”
“You’re a monster,” Dylan spat, but obeyed, pressing his lips to hers again and parting them with his tongue.
This time her mouth opened — not in response but from shock — and his tongue slid inside, meeting hers. She made a muffled sound of protest, but he continued, driven by desperation and something else he refused to acknowledge. Her tongue was soft, warm, and he kissed her deeper, losing himself, drowning in the sensation.
Sophie sobbed into his mouth.
The creature watched. Its black eyes, pupil-less, absorbed every movement, every emotion playing across their faces.
And the horror wasn’t in what it threatened them with, but in how it did it. No malice, no lust, not even cruelty for cruelty’s sake — only attention. This was not how a predator watches its prey, but how a researcher watches a specimen under glass: calmly, precisely, head slightly tilted so as not to miss a reaction.
“Enough. For now.”
Dylan pulled away from his mother, breathing heavily. Sophie stood swaying, her lips swollen, her eyes red. She looked destroyed.
“Why?” he asked, turning to the alien. “Why are you doing this?”
The creature tilted its head to the side, and there was something almost human, almost mocking, in the gesture.
“Because I can. Because I want to understand. Where is the line beyond which you stop being people and become animals? I want to see that line. And you will help me.”
It turned and moved into the darkness of the corridor, gesturing for them to follow.
“We need to run,” Dylan whispered, taking his mother’s hand.
But tentacles had already coiled around their wrists, gently but insistently pulling them forward.
“Where, Dylan?” Sophie said with a bitter smile, wiping her tears with the back of her free hand. “Where is there to run?”
They walked. The corridor widened, and the walls slowly shifted their hue — the dull gray warming, flushing amber, then gold, and nearer the hall the gold thickened, darkened, swelled into crimson, as if the space itself were bracing for something. A vibration grew in the air — a low hum that penetrated the bones.
A new chamber opened ahead — larger, brighter, and at its center stood objects that sent a chill down Dylan’s spine. He caught a glimpse of the black sphere gliding after them, taking its place under the high ceiling of the new hall, rotating silently like an invisible eye.
Two chairs.
With straps.
And a rack of instruments, glinting in the dim light.
The chamber was larger than any room they had seen before, domed, with walls pulsing a dull crimson light, as if veins ran somewhere inside them. At the center, on a raised platform, stood two chairs of dark material, fitted with wide straps — for wrists, ankles, waist. To the side was a rack of instruments glinting in the half-light: clamps, rods, thin needles, vibrators of clearly alien design, coated in matte black.
The creature stopped between the chairs, its tentacles swaying lazily in the air. It turned its head to Dylan, then to Sophie.
“I want to see you completely. Without coverings. Without protection.”
Its voice was calm, thoughtful, almost benevolent — and that made it even more terrifying. It pointed one of its tentacles at the floor before it.
“Boy. Undress your mother. Every piece of fabric. I want to see her open up.”
Sophie’s breath caught. She shook her head, backing away, but the tentacle coiling menacingly before her made her freeze.
“Don’t you dare,” she breathed, looking at Dylan. “Please, don’t.”
Dylan stood with his fists clenched. He felt his nails digging into his palms, his heart pounding somewhere in his throat. Her plea cut like a knife, but the creature’s black eyes burned with expectation.
“Mom, if I don’t do this...”
“I know,” Sophie finished bitterly.
She closed her eyes, and another tear slid down her cheek. Then she straightened, lifted her chin, and stepped to the center of the chamber, closer to Dylan.
“Do it,” she said dryly, like a doctor giving an order for a procedure. “Just make it fast.”
Dylan approached. His fingers were still trembling. He started with her jeans — dark, snug-fitting. He undid the button, pulled the zipper down. The fabric loosened, and he knelt before her, drawing the jeans down over her hips. Dark pubic hair flashed above the edge of her panties before the jeans slid down to her ankles, revealing her moderately slender thighs and calves. Sophie stepped out of them and now stood in only her undergarments — a cream bra and black bikini briefs, which he knew would be the next thing ordered off.
“Continue,” the alien said.
Dylan rose. His hands moved to the clasp of her bra at her back. He unfastened it, and the straps slid down Sophie’s shoulders. She caught the cups with her hands, instinctively pressing them to her chest, but Dylan gently, almost pleadingly, touched her wrists.
“Mom, please...”
Sophie sobbed but released her fingers, and the bra fell at her feet. Her breasts came free — full, with large nipples, areolas of a perfect shape that emphasized their beauty; despite her age, her breasts still looked firm enough. She stood before him, half-naked, and Dylan felt the ground give way beneath him.
He knelt again. Now — her panties. He took hold of the elastic at the sides.
Dylan looked up, searching for his mother’s eyes. She wasn’t looking down; instead, she turned her gaze away.
Slowly, the fabric pulled downward. The dark triangle of hair was revealed gradually, until the cloth slid down her legs and fell to the floor.
Sophie stood completely naked.
Her skin was covered in goosebumps, her arms hung limply at her sides. She stared somewhere to the side, into emptiness, as if trying to dissociate from what was happening. The light played across her body, emphasizing curves, hollows, the cleft between her thighs.
“Look down,” the creature’s voice whispered. “Directly before you.”
Sophie tensed nervously, understanding where her son’s gaze would go.
Dylan shuddered. He was on his knees before his mother. His gaze dropped. Face to face with her exposed sex, covered by a neat triangle of hair, the outer lips just below — he swallowed. Her scent hit him like a heady cocktail.
The creature stepped toward them. One of its tentacles rose and stroked Sophie’s cheek, damply, greasily. She squeezed her eyes shut but didn’t pull away.
“Good, mother. Now your turn.”
Sophie opened her eyes. Confusion swam in them, then horror, as the meaning of the words reached her.
“What?”
“Undress your son. I want to see all of him.”
She froze. Her gaze darted between Dylan and the creature’s black silhouette.
“No, please,” she breathed. “It’s ... I can’t.”
“You can. And you will do it. Or I will do it — but in a different way. I swear, you won’t like it.”
The tentacle squeezed her throat, forcing her to step forward, almost right up against Dylan, who was still on his knees.
“Fine,” she breathed, trying to keep her voice steady. “Let go.”
“Stand up,” she said to her son.
Getting up was hard. His legs shook, his head spun from the scent of her body, from the proximity of her bare skin. But Sophie was already reaching for his T-shirt, grabbing the hem and lifting it up.
Dylan raised his arms to help, and the T-shirt flew aside. The air touched his skin, and he felt defenseless. Sophie looked at him with resolve but without any enthusiasm, and her hands were already on the belt of his jeans, unbuckling it, pulling the zipper down. She could already feel the pressure from inside.
The sound of the zipper parting in the silence seemed deafening.
She crouched before him, pulling his jeans and boxers down together. His cock sprang free — youthful, already fully hard, despite all the horror, treacherously erect.
Dylan squeezed his eyes shut in shame.
He hated his own body for this honesty. His mind screamed that everything in him was terror, protest, the need to protect; but his body answered with one short, shameful “want,” and there was nowhere to hide that want.
