Cyn had always been a bit of a wild child. Even as a young girl, she had an insatiable appetite for sex and a brazen, unapologetic attitude to match. As she grew into a woman, her proclivities only intensified. She devoured men like a succubus, leaving a trail of satisfied yet utterly broken souls in her wake.
But lately, something had changed within Cyn. She felt a strange new energy coursing through her body, an all-consuming lust that bordered on feral. And to her shock and amazement, she could feel something hardening between her thighs – an unmistakable bulge that grew bigger by the day.
Glancing down at the obscene tent in her panties, Cyn bit her lip to stifle a moan. She was growing a cock, just like a male demon incubus. The thought made her head swim with taboo possibilities.
That night, Cyn prowled her usual haunts in a tight black dress, her straining erection barely concealed. She needed a partner for her depraved experiment – someone discreet and willing to keep her dark secret.
Spotted a shapely young man alone at the bar, Cyn sauntered over with a beguiling smile. “Buy a lady a drink, handsome?” she purred, leaning in close.
The man blushed and stammered but ultimately agreed. As they raised their glasses, Cyn made sure to “accidentally” brush her hips against his. The man’s eyes widened as he felt the incredible girth of her demon cock press into his thigh.
“Care for a private room upstairs?” Cyn suggested with a wink. “I’ve got something special I want to show you.”
Barely able to speak, the man nodded vigorously and followed the sexy succubus up to the VIP area. As soon as the door closed, Cyn pushed him against the wall and captured his lips in a searing kiss.
She palmed his erection through his slacks as her tongue plundered his mouth. “I need you to promise,” she gasped, breaking away. “Promise not to tell anyone what we’re about to do.”
“Wh-what are we doing?” the man stammered, his voice gone breathy with lust.
Cyn only smiled. She reached down and yanked open his fly, freeing his straining cock. But then, in one smooth motion, she pulled aside her panties to reveal the massive, throbbing demon dick that strained up towards her belly.
The man’s jaw dropped as Cyn stroked her inhumanly large erection. “I’ve recently acquired a bit of a situation,” she explained, her voice a seductive purr. “No one must ever know. Can I trust you to keep my secret, darling? While I fuck this tight little pussy of yours with my huge new cock?”
“I… I promise,” the man babbled, his eyes never leaving the succubus’s enormous dick. “I won’t tell anyone, I swear! Just please, oh god, please fuck me!”
Cyn grinned, triumphant and aroused. She spun the man around and bent him over a chair, hiking up his pants legs. “Don’t worry, sweet thing,” she cooed as she lined up her demon cock. “I’ll be gentle… at first.”
Then with a powerful thrust of her hips, Cyn buried her massive, inhuman cock deep into the man’s virgin ass. He cried out at the sudden intrusion, clenching around her girth. “Oh fuck yes,” she groaned, starting to pump away. “I knew I chose the right slut to break in my new toy…!”
And so Cyn began to live out her filthy incubus fantasies in secret, using her irresistible charms to lure men into being her cock-testers. She never risked going too far, always stopping just shy of her climax to avoid leaving any incriminating evidence behind.
For Cyn was determined to keep her devilish secret safe – even if it meant holding back her own pleasure, night after night. Her new cock was her darkest treasure, to be enjoyed in private debauchery with the most trusted of her many partners.
