The call came just as Sophie was lounging on her couch, coffee cup balanced in one hand, her birthday playlist humming low from the kitchen speaker.
“Miss Sophie? This is Daniel from the front desk,” the concierge’s voice carried its usual polite crispness. “We’ve just received a ... very large delivery for you. Shall I bring it up?”
Her brow furrowed. “How large are we talking?”
“Well,” he chuckled, “large enough that I’ll need the two-wheel dolly. Should I?”
Sophie’s curiosity flared instantly. “Yes, please. Send it up.”
Minutes later came the knock. She padded barefoot to the door, tugging her silky robe tighter. When she opened it, she blinked. Daniel stood there, wrangling a towering cardboard box strapped to his dolly.
The thing was enormous—easily six feet tall, maybe thirty inches square, the brown surface unmarked except for black stencilling: GAN2025, PHUK Enterprises, Beijing China.
Daniel grinned. “Happy birthday, Miss Sophie. Where should I put it?”
“Uh ... right in the middle, I guess.” She stepped aside, watching him wheel it into her condo’s airy living room. The late-morning sun caught the pale gold in her hair and spilled across the box like a spotlight.
Once Daniel left, Sophie circled her new mystery. Her fingers skimmed the plain cardboard, searching for a seam or flap. Halfway around, she spotted it—a tiny red string set into one edge, about waist height. Next to it, neat Chinese characters marched down the side.
She grinned at her own cleverness, snatching up her phone and opening her translate app. Holding the camera steady, she waited as the text resolved into English:
“To open, pull red string and stand back.”
A laugh bubbled from her lips. “Well, that’s dramatic.”
She gave the string a firm tug. At first, nothing happened—then a soft hiss, followed by a faint mechanical click. An opening appeared along the box’s front panel, and something slid out.
An envelope.
It was heavier than it looked. Inside, she found a chunky black remote bristling with buttons and an instruction booklet the size of a paperback.
Settling onto the couch, she began to read.
“Congratulations, you are the proud owner of the GAN2025, the latest in adult entertainment. GAN (Goes All Night) is the most realistic multi-function sex toy ever invented. It will provide hours of pleasure to the discerning owner. Our breakthrough manufacturing process has created the most lifelike body parts and skin ever found on an adult toy. “ Turning the page, Sophie reads further, “The GAN2025 is equipped to operate in multiple modes. It comes equipped with a variable-length tongue, adjustable by using the handy remote. It is able to provide oral and anal services to whatever depth you desire. The male member is also adjustable in length using the remote to fill every need. In addition, the mouth is equipped with suction ability to achieve maximum oral stimulation for the owners. (Note: Care must be taken by male owners when using this function) For our dominant female owners and our male owners, the GAN2025 is capable of receiving any length anally up to 12 inches.”
By the second page, her cheeks were warm. She curled a leg under herself, robe loosening slightly at the thigh.
She bit her lip, flicking to the final page. A QR code.
Without hesitation, she scanned it.
The box gave a low hum. Panels slid apart, revealing ... him.
Sophie’s breath caught.
He was impossibly perfect—tall, blond, blue-eyed, sculpted like he’d been carved out of sunlight and sin. Broad shoulders, hard chest, taut abs, and between his muscular thighs ... God. Even soft, he looked dangerous.
Her robe slipped further as her thighs pressed together. She reached for the remote, thumb finding the Power button.
A soft whir rose from inside him. His eyes opened—clear, crystalline blue—and locked on hers.
In a voice that dripped heat straight down her spine, he said,
“Happy birthday, Sophie. How many orgasms may I give you today?”
Sophie didn’t answer his question right away.
She just stood there for a heartbeat, eyes locked on his, robe hanging loosely from her shoulders, the faintest smirk curving her lips.
Then, without a word, she stepped forward and reached for his hand.
Warm. Shockingly warm.
The synthetic skin felt almost too real—smooth over firm muscle, his fingers curling gently around hers the moment she made contact.
“Come with me,” she murmured.
He followed without hesitation, the faint hum of hidden servos barely audible over the muffled music from the living room. The tall, perfect stranger moved with fluid precision, his steps matching hers exactly as she led him down the short hall toward her bedroom.
The door swung open with a push of her hip. Sunlight poured across her queen-sized bed, spilling over the pale sheets and scattering across the floorboards. The air held the faint scent of her perfume—vanilla and something floral—wrapped around them like an invitation.
Sophie guided him to the edge of the bed, studying his face as if waiting for some imperfection to reveal itself. There was none. The symmetry of his jaw, the impossible clarity of his eyes, the slight rise and fall of his chest—all maddeningly, achingly human.
Her gaze drifted down, lingering on the heavy, lifelike weight between his thighs. She could almost feel herself getting wetter just looking.
“You’re very ... impressive,” she said, her voice playful but threaded with real desire.
“Thank you, Sophie,” he replied in that deep, rich tone. “Would you like me to demonstrate my capabilities?”
Instead of answering, she released his hand and stepped back. Her robe slipped off one shoulder, revealing smooth caramel skin and the delicate curve of her collarbone. She watched his gaze follow, that hint of a smile never leaving his lips.
“Not yet,” she said. “I want to take my time with you.”
She circled him like she had the box earlier, fingertips grazing his skin as she tested the feel of his chest, the ridges of his abs, the hard slope of his back. Every inch felt hot to the touch, textured just like living flesh.
When she moved back in front of him, she picked up the remote from her nightstand.
Her thumb slid over the buttons, finding one labelled Extend.
She pressed it.
The change was immediate—his cock thickening and lengthening in a smooth, hypnotic motion until it hung heavy and full between his thighs.
Her lips parted.
“Oh ... we’re going to have fun.”
He didn’t blink. “How shall I begin?”
Sophie smiled, stepping closer until her breasts brushed his chest. “On your knees,” she whispered. “Show me what that tongue can do.”
The robot sank to his knees at the edge of her bed, eyes locked on hers, waiting for command.
Sophie perched on the mattress, remote in hand, her robe pooling around her hips. Her skin tingled everywhere—anticipation as thick as the sunlight spilling in through the window.
She found the button labelled Tongue and pressed it once.
His mouth opened. A smooth, pink tongue extended just a little—normal length at first. She tilted her head, curious, then pressed Extend.
It slid farther out ... then farther still. Six inches. Eight. Ten. The movement was so precise it almost looked unreal, until she reached down and brushed her fingertips over it. Warm. Wet. Just rough enough.
Her thighs shifted apart without thinking. “Let’s see how good you really are.”
He leaned in, the tip of his tongue dragging slowly up her inner thigh before gliding toward the soft, aching heat between her legs. Sophie gasped at the first swipe over her clit—firm enough to be felt, gentle enough to tease.
She tapped the Speed button, watching his tongue flick faster, curling and flattening as it worked her. Her hips twitched, breath catching with each pass.
Another button—Mode. The rhythm changed, side-to-side licks that made her toes curl. She guided him closer, and his tongue slipped lower, teasing her entrance, then deeper still.
“Oh ... fuck...”
One more press of Extend and she felt it—long, slow, sinuous strokes reaching inside her in ways no human tongue could. She let herself sink back onto her elbows, eyes fluttering closed.
Then his tongue retreated, tracing a slick path lower. She startled slightly when it circled her tightest spot, warm and insistent.
“Mmm ... bold,” she breathed.
The tip pressed gently, teasing, before slipping just inside. Not enough to hurt—just enough to make her gasp and shiver. It explored her there in slow spirals, alternating between her ass and pussy until she was trembling.
She pulled his face up slightly, thumbing the Suction button. The moment his lips sealed over her clit, she knew—oh, this was different. Stronger. More focused. Better than her Rose by a mile.
“Oh my god...” Her voice cracked as the suction pulsed, drawing every nerve tight. His tongue danced around the sensitive bundle while his fingers—she hadn’t even noticed them moving—slid inside her, curling perfectly against that spot that made her knees want to give out.
Another hand—warm, steady—spread her open, and one slick finger teased her asshole in lazy circles before pressing lightly. The double sensation hit her like a lightning strike.
Her breath came in ragged bursts. The suction grew stronger, the fingers inside her pumping harder, that teasing finger outside slipping deeper in time with each stroke.
“Ohhh ... yes ... don’t stop—”
Her body arched, pleasure crashing over her in hot, uncontrollable waves. She cried out, hips jerking, hands gripping his hairless head as the suction and fingers kept working her through every pulse and spasm.
Only when her legs trembled so hard she nearly fell sideways did he ease back, suction fading, tongue withdrawing, fingers sliding free.
Sophie lay panting, chest rising and falling, robe open and forgotten, every nerve still humming.
She grinned down at him, breathless. “Happy birthday to me.”
Sophie lay there for a moment, letting her heartbeat slow, still feeling little aftershocks run through her. The remote was still in her hand, its glossy buttons catching the light. Her gaze drifted to him—kneeling patiently at the side of the bed, face calm, eyes alert, as though nothing had just happened except the thing he was built for.
“Well,” she murmured, stretching like a cat, “let’s see what else you’ve got.”
She sat up, letting the robe slip completely off her shoulders, and thumbed the Length control for his cock. The change was instant—smooth, almost hypnotic, as he swelled from his natural size to something thicker, longer, stopping at an impressive eight inches. Her hand curled around it—warm, firm, perfect.
“Not bad...” She smirked, then pressed the Suction button again, this time setting it to Low. He leaned forward, lips closing gently over her nipple. The sensation was delicate at first, then teasingly rhythmic, his mouth tugging and releasing just enough to make her breath hitch. She guided his head to her other breast, shivering when he switched without losing that steady, pulsing draw.
