As the sun broke through the windows, casting its golden morning light on Lily's penthouse, she yawned and stretched before finally opening her eyes. The previous night's escapade still lingered in her mind, a faint echo of her wanton pleasure.

“I so wanted to continue wearing you, my lacey temptress," Lily mummed, as her hands followed her abdomen toward her hips, "But, surely you are soiled by all of my lurid fluids released last..." She paused, confused, as the ivory vintage lace garment was clean and dry. There was no sign of damage or moisture. Lily smiled, deciding she may never truly comprehend what occurred the previous night.

At her work desk, not even the most intricate digital models could match the vivid colors that splashed across the canvas of her mind. Those carnal memories were so tangible, she could almost taste their essences on her lips.

This mysterious affair stirred something within her, and it wasn't simply the fire of passion. Rather, it felt like an epiphany, the faintest glimmer of truth and understanding — a truth she knew she shouldn't ignore about her relationship with Amelia.

Lily hesitated, wondering if she was losing her grasp on reality. She was a savvy businesswoman, not a guileless teenager, yet her pulse quickened with fervid anticipation.

As the days passed, Lily found herself growing slightly obsessed. She wore her mysterious garment as often as possible. The visions of Amelia were growing increasingly vivid in her mind, painting an intoxicatingly alluring picture that surpassed even the seemingly innate connection they had shared since childhood.

She marveled at this strange turn of events, which transcended the boundaries of friendship. Did her longtime comrade secretly harbor similar feelings, or was it merely a fluke of her wildest dreams? Lily could not help but find herself entranced by this puzzle.

Lost in these ever-deepening thoughts, she'd lost all track of time. It wasn't until a welcome alert broke through her reverie, pulling her back to Earth: an incoming video call from Amelia.

Mustering a less-convincing façade than she’d like, Lily endeavored to placate her friend's concerns. "So, Amelia, what's up?" Lily asked clumsily, chastising herself internally for her awkward greeting. Her friend's beautifully sculpted face appeared on the screen, her hazel eyes shimmering with kindness. Amelia's wavy hair cascaded over her shoulders, framing her concerned face perfectly.

Amelia countered, "Lily, are you alright?" She continued, "You sound off and you didn't say much about what happened all of those nights ago. Just that you discovered something unusual. You didn't even describe or show me the vintage lingerie you bought."

Lily's thoughts were interrupted by Amelia's voice. She shifted her gaze back to the computer screen, plastering a smile on her face. "Oh, Amelia. I'm fine, really. There's nothing to worry about. I guess I was just taken aback by what I found. It was just so... strange." She hesitated, mentally debating whether to reveal more.

Her thoughts were again interrupted, this time by Amelia's web cam breaking loose, its point of view lowering to her hips, exposing Amelia's curves and a flash of black lace. "Whoa, what the-" Amelia exclaimed, trying to reposition her screen.

Lily felt her face flush, the garment took advantage of the situation by once again stretching and squeezing Lily's sensitive parts. Unease crept in Amelia's eyes when she noticed Lily had seen her underwear, creating an awkward space neither woman could navigate through skillfully.

Amelia cleared her throat, "Lily, I'm so sorry. The clasp slipped, and my camera-" Before she could finish, Amelia caught an abrupt gasp from her friend's end. "Lily, your face is flushed. What's wrong?"

"Nothing," Lily practically moaned, her fingers slipping inside her ivory silk robe. "I just... I needed to... adjust myself."

Amelia's brows knitted in confusion and curiosity, but she didn't push the issue, instead changing the subject to ease the awkwardness. "So, did I ever tell you about my new side hustle?" she asked, her usual bright and bubbly tone returning.

The mention of a side hustle from Amelia piqued Lily's curiosity. She felt a rush of excitement, like they were back in their teenage years when they used to share secrets and embark on exciting adventures together. "No, you didn't," Lily said, trying to maintain her composure.

Amelia leaned in closer to the camera, her eyes sparkling with mischief. "Well, I can't tell you everything just yet, but let's just say I now own controlling interest in an exciting new fashion venture that involves high-end lingerie. It's still in the early stages, but I've already found some suppliers who craft unique pieces that transcend traditional undergarments. I think it could be a real game-changer in the industry."

Lily's heart skipped a beat, her hands still firmly between her legs as an unexplainable heat emanated from between her thighs. "That sounds amazing, Amelia," she said, fighting the urge to pleasure herself.

"I'm so glad you think so, Lily." Amelia's expression turned thoughtful. "I hope you might be interested in helping me when things get rolling. I could really use your business savvy to help make this venture a success. Obviously, I'll make sure there’s fair compensation for your help, but I'd give anything to work alongside you again. Maybe we can even wear some of these designs together for old times' sake."

"I--I'd love that." Lily choked out, unable to process the flurry of sensations coursing through her being. The shadow had transformed her once ordinary work desk into a playground of pleasure and raw emotion; a sanctuary where she could indulge in her deepest desires, anchored by the presence of her most trusted confidant.

"How long have you been setting up this venture?" Lily asked, trying to regain her bearings.

"For a few months, actually," Amelia answered cheerfully, unaware of the tumult in her friend's world. "The idea came to me when I was investigating a lace mill overseas. I stumbled upon this unique supplier, and their design schematics were too enthralling to pass up. I instantly thought of your capabilities and decided this would be the perfect venture for us."

"Responsibly sourced, of course," Lily chuckled through a gasp. Her hand trembled under the desk. As if in answer, the shadow intensified again, sucking hard against her most intimate flesh. She bit her lip so hard she tasted blood, but the bite of pain only heightened her pleasure.

"My textile mills? No, not yet" Amelia continued, unaware of her friend's throes of passion, "They're overseas sweatshops. I can admit that. Honestly, I've encouraged some unseemly aspects for the sake of growth, but something tells me this venture might require more compromise than I initially anticipated"

Amelia's words echoed in Lily's ears, her mind blurred by the conflict between her duty to help her best friend and the overwhelming, all-consuming sensations between her legs. The shadow's touch became more demanding, its lacey grip maddening as it beckoned her, whispering sweet promises of release right at the edge of her consciousness.

"I mean, I saw the women. I saw their eyes, begging for help. But the profits..." Amelia's voice trailed off as her face morphed into a frown, her lips silently mouthing an inner struggle between ethics and ambition. At Amelia's admission, the shadow fell quiet, strangely subdued as if absorbing her every word. The bewitching undergarment eased its grip on Lily, and for a moment, its touch disappeared entirely.

Lily, however, needed that control, that push to the edge and then relief that kept her from climaxing. Without it, her fingers immediately delved below the shadowy line of the lingerie, sliding between indescribably slick lips soft as the newest silk, slipping inside herself as groans tore free from her pillowy lips. Fingers danced along her slippery walls in response to the pressure cooking inside her. Plunging two deep within her, she gasped, shamelessly bucking her hips as her other arm braced her weight to prevent being heard—it was a battle against overwhelming pleasure.

Deciding to change the subject back to something more pleasurable, a smile curled onto Amelia's lips as she asked, "So, I showed you mine, how about you show me yours, specifically that lacey treat that made you so ecstatic?"

Lily hesitated momentarily, contemplating the proposition. Eventually, she relented, allowing her inhibitions to dissolve like morning mist. Her breath hitched as she curled her fingers around the hem of her robe, opening it up ever so slowly to reveal the shadow-infused garment she wore beneath.

As Lily's robe opened wider, there was no doubt Amelia's gaze followed, Amelia almost emitted a gasp as she said, "Wow, what a small world. Those come from a textile mill I own."

Amelia's cheeks turned rosy, a mixture of shame and pride. "It's one of my most successful sweatshops, and I've always taken pride in that, no matter the conditions—"

Lily's arousal peaked at the erotic confession. Her lust for Amelia was no longer a manipulation of shadow. She craved Amelia, wanted to devour her best friend, who remained blissfully unaware of the hidden sensation between Lily's thighs.

The shadow had other intentions. Amelia was the owner of the sweatshop whose occupants it had vowed its loyalty to, despite its inability to understand why. It had a purpose to complete, one that it was not yet fully aware of, and it involved meeting Amelia, in person.

The shadow reigned in Lily's lustful desire, realizing that it must act strategically. It wanted to bond and enmesh not just with Lily, but with Amelia too. This, it perceived, was the path to fulfilling its enigmatic existence.

"Listen, Amelia, I need a favor." Lily made her voice firmer, as if she were negotiating an important partnership deal instead of inviting a soul-consuming shadow fusion. "Follow your intuition and come to New York. Soon. Trust me." At Lily's desperate plea, the shadow curled up like a cat seeking affection.

Amelia eyed the sudden shift, and her nose twitched in curiosity before she caught herself and shook her head. "Right, sure thing, Lily. I'll book the first flight I can find."

"Wonderful. I can't wait to see you in person. I've really missed that," Lily practically growled into her screen, the ache between her wanting thighs spreading in a feverish wave to her eager nipples. She plucked at the tight buds through her lingerie, her whispers carnal and lascivious.

Amelia's eyes blazed with unspoken desire as she locked her gaze on her friend. Those hazel orbs widened, pupils dilating in realization as they fell on Lily's heaving chest. "I-I've missed you too, Lily. Seeing you like this... it's like we're back in college; staring at each other all night."

Lily's voice was breathless, yet quietly forceful, her breathing quick and shallow, and her chest rising and falling as Amelia's heated gaze bore into her from the webcam.

Amelia blinked twice, realizing her slip of control, and licked her lips. "S-sorry, Lily. I just... didn't know you felt that way." She stammered, but her voice was heavy with lust, betraying the words she spoke.

"We'll talk once you get here," Lily said softly, her green eyes sparkling, pinpricks of light that seemed to dance like fireflies as they caught the fading afternoon light.

A sudden shiver ran down Amelia's spine, her nerve endings now raw and exposed, a weakened fortress that Lily had assaulted with nothing more than her gaze.

"The fastest flight I can find," Amelia managed to say before ending the call.

Once the call was over, Lily could no longer be contained, not by conformity, not by social norms, not by the decency she'd tried to uphold in the presence of her friend, nor even by an ethereal force. She stood and ripped at her own clothing, desperately removing fabric that limited her access to the fire between her thighs.

Without prodding, Lily sank her hand in. Her waxen fingers slid over her wanton lips, slipping inside her molten core once again.

A sly smile crawled across her face as the pleasure mounted, a tantalizing dance of her own fingertips throbbing inside her walls as her hips pumped up and down, desperate in their carnal quest.

With the shadow's guidance, her world was now a blur of need, a fever dream of pleasure. It molded her to its will with expert, ghostly precision.

"You will do this to Amelia," The shadow whispered in Lily's mind, in her voice, as if it were her own thoughts urging her to indulge in the perverse.

A sharp gasp stuck in her throat. Lily thrust harder, faster. Her slick fingers sought the sweeping crest of orgasm teetering on the horizon of her body. She rode her hand to blissful rapture, drawn into the tide of addiction that painted her soul with the shadow's every whim.

"Amelia will do this to you." The shadow again whispered into Lily's mind. It enticed her, egged her on. Fueled by her growing obsession with her best friend, Lily submitted to the entity's demands.

Her moans grew louder, reaching an ear-splitting crescendo. Whimpers and gasps escaped her as a ragged stream.

"You will taste Amelia's essence," The shadow hissed in Lily's mind, insistent and relentless in its demands, pushing her beyond the brink. Lily's dreams of Amelia twisted in her brain, visual fantasies playing out before her eyes. Each thought served to launch Lily deeper into the forbidden desire.

The image in front of her wavered and blurred, obscuring the line between reality and fantasy.

"Amelia will taste..." The shadow didn't even finish before Lily's mind exploded in a surge of intense pleasure. She threw her head back and screamed, her orgasm rippling through her, sending shockwaves throughout her entire body. Her vision went white, and for a moment, all she could hear was the pounding of her own heartbeat, reverberating in her ears like a field of drums.

As her vision slowly cleared, Lily's mind returned to the present. She pulled her hand out from between her trembling legs and slumped back in her chair, utterly spent.

The release had left her barely conscious, the sensations still thrumming deep within her core, aftershocks pulsating like echoes vibrating through her very essence.

Panting, she stared blankly at the far wall of her penthouse, her mind addled as the shadow basked in the intensity of her orgasm. The garment wrapped its spectral form around her thigh, kneading and rubbing her sated flesh as if it required a feeding for the pleasure it had elicited.

The shadow reveled in the taste of her heavenly nectar. Unbeknownst to Lily, the shadow had gained a bizarre predilection for the sweetness of human lust. Her essence had fully awakened the shadow, bestowing it freedom and absolute sentience on this plane of existence. Lily had provided precious energy to the shadow, granting it clarity of thought, emotion, and a keen understanding of the human condition.

The trap was set.
