The air in their apartment smelled of popcorn and lazy Sunday afternoons. Jill was sprawled on the worn corduroy sofa, one pigtail tucked behind her ear, scrolling idly through her phone. Across from her, Sarah sat cross-legged on the floor, a tablet balanced on her knees, her bright red hair a vibrant splash against the beige rug.
“Oh my god, Jill, look at this!” Sarah’s voice was a sudden exclamation, shattering the quiet. She thrust the tablet toward her sister.
Jill didn’t even look up. “If it’s another video of a kitten trying to fit into a teacup, I’ve seen it.”
“No, it’s better! It’s a new shop. On Oak Street. Right near us!”
“A shop.” Jill’s tone was flat. “Fascinating.”
“Not just a shop,” Sarah insisted, scrambling onto the sofa, jostling Jill. She pointed at the screen. “Look. ‘Esoterica Arcana.’ It says they’ve got crystals, tarot, incense ... and ‘unconventional implements for personal exploration.’ That sounds so cool!”
Jill finally glanced over. The website was a deep purple, with swirling silver fonts. It looked like every other vaguely mystical boutique that popped up in their artsy neighborhood. “It sounds like they sell overpriced rocks and bad incense.”
“You are such a cynic!” Sarah pouted, her lower lip jutting out. At eighteen, she still had a knack for making that expression devastatingly effective. “Come with me. Please? I don’t want to go alone. It might be weird.”
“It will be weird. That’s a guarantee.” Jill sighed, setting her phone down. She looked at her younger sister—the wide, eager green eyes, the spray of freckles across her nose that seemed to dance when she got excited. Sarah was her opposite in so many ways: boundless enthusiasm to Jill’s guarded skepticism, a bubbly openness to Jill’s more reserved nature. And yet, they were inseparable. “Fine. But if someone tries to read my aura or sell me a ‘blessed’ paperweight, I’m leaving.”
Sarah squealed, launching herself at Jill for a quick, tight hug. “You’re the best! Get your shoes on!”
Oak Street was a narrow, tree-lined avenue dotted with quirky boutiques and coffee shops. Esoterica Arcana was nestled between a vintage record store and a vegan bakery. The storefront was understated: a simple black door with a silver handle, and a single, elegantly lettered sign in the window. No garish displays, no neon ‘OPEN’ sign. It felt ... quiet.
Sarah pushed the door open, a little bell tinkling softly above them.
The inside was a stark contrast to the bright afternoon. It was dim, illuminated by the warm glow of dozens of salt lamps and flickering candles in glass jars. The air was thick with a complex scent—sandalwood and patchouli, yes, but underneath it was something else, something earthy and slightly sweet, like petrichor and dried herbs. Soft, ambient music, all humming tones and distant chimes, floated through the space.
“Whoa,” Sarah whispered, her eyes wide.
“Told you it’d be weird,” Jill murmured back, but even she had to admit there was an intriguing atmosphere. It felt less like a shop and more like a library of oddities.
The space was deep, with high shelves lining the walls, crammed with books whose spines bore strange symbols. Glass cases displayed glittering geodes, polished skulls of small animals, and intricately carved wooden boxes. In the center of the room, a large, round table held a magnificent crystal ball on a stand of wrought iron.
There was no one at the small counter near the back. The place seemed empty.
“Hello?” Sarah called out, her voice echoing slightly.
A curtain behind the counter parted, and a woman emerged. She was older, perhaps in her sixties, with a cloud of silver hair and eyes so pale blue they were almost grey. She wore a simple black dress and a necklace of what looked like bone fragments. She smiled, but it didn’t quite reach her eyes.
“Welcome,” she said, her voice a smooth, low rasp. “First time visitors?”
“Yes!” Sarah chirped, stepping forward. “We saw your website. Your shop is amazing.”
“Thank you. My name is Elara. Please, browse. The sections are ... categorized by purpose.” She gestured a slender hand toward the back of the store. “Manifestation and meditation tools are to the left. Divination and communication to the right. And in the rear...” Her pale eyes flickered between the two sisters, a knowing glint in them. “The rear is for more ... tactile explorations.”
Sarah was already moving, drawn like a moth to the strange light. Jill followed more slowly, her fingers trailing over the spine of a leather-bound book titled On the Sympathetic Vibrations of Flesh and Spirit.
They wandered past shelves of polished wands, bowls of strange resins, and jars filled with colored sands. The ‘tactile explorations’ section was separated from the rest of the shop by a heavy velvet curtain of deep crimson. Sarah didn’t hesitate, pushing it aside.
This area was smaller, more intimate. The lighting was even lower, coming from a single violet-tinted lamp on a low table. The shelves here held fewer, but more peculiar items. There were phallic-shaped stones of rose quartz, smooth and cool to the touch. There were strange leather harnesses with delicate chains. And then, on the bottom shelf of a central display case, they saw them.
Jill stopped short.
They were in small, clear glass terrariums, about the size of a shoebox. Each contained a bed of soft moss and a few smooth stones. And in each one, nestled in the moss, was a ... creature.
It was the only word for it. They were small, perhaps six to eight inches long from what appeared to be a rounded, bulbous base to the tip of their longest appendage. Their bodies were a deep, iridescent indigo, shimmering with hints of violet and black under the strange light. They had no discernible face, no eyes, just a smooth, rounded ‘head’ area. From their main body sprouted several slender, prehensile tendrils. These tendrils moved slowly, sinuously, coiling and uncoiling with a life of their own. They were translucent at the tips, fading into the darker color of the body, and they pulsed with a faint, internal bioluminescence—a soft, slow rhythm like a heartbeat made of light.
Sarah crouched down, her face almost pressed to the glass. “What are they?”
A small, elegantly printed card stood in front of each terrarium.
‘Euphoria-Symbiont, Model ES-7. A bio-familiar, specially bred and bonded for intimate somatic resonance. Provides unparalleled, adaptive pleasure stimulus through empathic tactile interface. Responsive to user’s bio-rhythms and emotional state. Self-cleaning, low-maintenance. Satisfaction guaranteed.’
Below the description was a price that made Jill’s eyes water.
“They’re ... sex toys,” Jill said, her voice hushed with a mix of disbelief and a strange, creeping fascination.
“They’re magical sex toys,” Sarah breathed, her eyes shining. “Look, Jill! They’re moving. They’re alive.”
One of the creatures, as if sensing their attention, uncoiled a tendril and pressed it against the glass directly where Sarah’s finger was. The tip was a delicate, almost flower-like bloom of finer filaments. It left a faint, moist-looking spot on the glass.
“It’s so ... beautiful,” Sarah whispered.
“It’s a tentacle monster in a box, Sarah.”
“It’s not a monster,” Sarah argued, standing up and turning to her sister. Her cheeks were flushed. “It’s a bio-familiar. It’s trained! For pleasure! Don’t you think that’s incredible?”
Jill felt a heat rise in her own cheeks. She crossed her arms over her small chest. “I think it’s insane. And gross. And probably illegal in several states.”
Sarah’s expression shifted from wonder to stubborn determination. Jill knew that look. It was the look that had gotten them both thrown out of a karaoke bar after Sarah tried to climb on stage, and the look that had convinced Jill to get matching (tiny, discreet) tattoos on their ankles.
“I’m getting one,” Sarah declared.
“You are not.”
“I am! I have birthday money saved up. This is way better than a new pair of boots.” Sarah’s gaze was locked on the creature. Its tendrils were undulating in a slow, mesmerizing wave.
Jill grabbed her sister’s arm. “Sarah, be serious. You can’t just buy a ... a living thing ... for that. It’s weird. It’s ... what would you even do with it?”
Sarah turned to her, her green eyes wide and utterly earnest. “What do you think you do with it? The card says ‘intimate somatic resonance.’ It’s for pleasure, Jill. Real, amazing, magical pleasure. Don’t tell me you’ve never been curious about ... more.”
Jill’s mouth went dry. Of course she’d been curious. She was twenty-one, with a fiery streak and a body that felt constantly alive with unused energy. But her explorations had been private, mundane—battery-operated and discreet. The idea of something living, something that responded ... it sent a jolt through her, a cocktail of revulsion and a deep, secret thrill.
“It’s different,” was all she could manage.
“That’s the point!” Sarah said, her voice dropping to an excited whisper. “Come on, Jill. Don’t you ever get tired of the same old thing? Don’t you ever want to feel something you’ve never felt before? Something ... unreal?”
Before Jill could answer, Elara’s smooth voice came from behind the curtain. “They are quite sensitive. They can feel your anticipation from here.”
