X Reunion (Cosmo The Seedrian)

"You're probably very confused," Cosmo said softly, her voice like a gentle breeze carrying hints of distant stars. Tails stared, dumbfounded—not just by her sudden appearance, but by a beauty that hit him like a cosmic wave: porcelain skin glowing with faint bioluminescence, eyes like deep emeralds holding secrets of galaxies, her lithe form draped in vine-like tendrils that accentuated every curve. It was bizarre—every fiber of his being urged him to close the distance, to taste her lips, yet she was a stranger. What madness was this, from any realm or dimension? "Allow me," she murmured, a delicate flower blooming in her palm. Its petals unfurled with a sweet, intoxicating nectar scent that enveloped him, sharp and floral, flooding his senses. Tails clutched his head, knees buckling as he collapsed onto his back, the world spinning.

As he lay there, a torrent of "memories" crashed over him—not his own, but vivid as lived: meeting Cosmo amid the chaos of the Metarex war, her gentle hand in his as they soared through starfields, laughter echoing in stolen moments between battles. Falling for her slowly, her soft fur brushing his during quiet nights on the Blue Typhoon, sharing dreams under alien skies—the warmth of her body curled against him, her scent like fresh rain on blooming flora. Comforting whispers after close calls, her tears on his cheek when Shadow nearly ended him trying to shield her. Then the heartbreak: her sacrifice, body dissolving into light to save the universe, forcing him to fire the shot that sealed her fate. All that remained was the potted plant, a fragile echo of her essence, which he'd nurtured in silent grief.

Tails bolted upright in bed, heart pounding, spotting a tray beside him: herbal medicine and steaming tea, its aroma earthy and calming. He sipped slowly, the warm liquid easing the ache in his temples. "What... did you do?" he asked Cosmo, who perched on the bed's edge, her presence both ethereal and grounding. "I know those aren't my memories—I'd remember someone as vital as you." Silence stretched, heavy with unspoken wonder. "Is it weird that I'm... still overjoyed to see you, Cosmo? Those flashes weren't mine, but my soul's singing. Feels right, somehow." He paused, rubbing his forehead. "Also, notes on the X-Tornado? Why haven't I built that yet?"

Cosmo met his gaze, taking his hand in hers—her touch cool yet electric, fingers intertwining naturally as he squeezed back. A small smile softened her features. "You've figured it out: you're not my Tails. Long ago, in my universe, we shared a bond I longed to last forever. Different species, different worlds, but we clicked—understood each other's quiet fears and joys like no one else." She glanced at their joined hands, thumb tracing his knuckles. "But after I sacrificed myself to ensure that universe's future, dissolving into energy... what lingered was this plant form." Pause hung, thick with sorrow. "My Tails couldn't bear seeing it; the pain was a bullet to the chest. He learned it could sustain me, but reblooming needed something rare—a perfect convergence. Devastated, he shipped me across dimensions to another you, hoping I'd find new life. I don't blame him; revival was impossible there." Her eyes lifted to this Tails, shimmering with gratitude. "But you... you made it happen."

"How?" Tails whispered, the pieces clicking despite the surrealness—he'd seen stranger in his adventures. "What makes me special that another Tails couldn't trigger this?" Cosmo's smile bloomed soft as she pressed her palm to his chest, right over his racing heart; warmth spread from her touch, like sunlight through leaves. "What?"

"Your heart," she chuckled lightly, though her eyes held depth. "Cheesy, right? But my essence sensed your loneliness—no true love to fill it. I couldn't let another Tails ache like that. Plus, your world's air is purer than my dimension's polluted skies; it nourished me easier." She lingered, hand flat against him. "I've been watching you for ages, feeling your joys and doubts."

Tails flushed neon red. "Wait—how long exactly?"

Cosmo laughed, a melodic sound that eased the tension. "Long enough to see you evolve: Sonic's eager sidekick to a standalone hero, battling identity woes, then embracing your playboy phase." Her chuckle deepened, eyes twinkling. "I've caught some fascinating shows, to put it mildly." Tails buried his face in his hands, mortified, but she gently lifted his chin, her fingers grazing under his jaw— a feather-light trace that sent unexpected shivers down his spine, stirring heat low in his belly. "I won't pretend I'm not intrigued by the pleasures you've shared with others."

"But you didn't bloom just for that, did you?" Tails ventured, catching her drift, his pulse quickening at the implication.

Cosmo nodded, cheeks tinting a soft pink. "Yes and no. I need you to send me back—to my dimension, my Tails. No offense; you're kind, but you're not him." Tails nodded slowly, understanding the ache of lost love all too well. "However," she continued, blush deepening as her hand slid to his inner thigh, fingers pressing with deliberate warmth that made his breath hitch, "I wasn't fibbing about my curiosity. When I reunite, I want it explosive—the ultimate love. But first..." Her smile shifted mischievous, eyes locking with heated promise. "Care to satisfy it? My rule: no vaginal penetration—that's for him. Everything else... yours to explore." Her touch inched higher, possessive and inviting. "Interested?"

"You're... stunning," Tails admitted quietly, voice husky, "and damn persuasive." Her hand ventured boldly up his thigh, nails grazing through fur, igniting sparks that drowned any lingering morals. "Fine," he smirked, desire winning out. "I'll get you primed to blow his mind." Cosmo pounced then, pinning him to the bed with surprising strength, her body warm and yielding against his, lips hovering close as the air crackled with promise. Tails knew—this was about to be unforgettable.
