Cellia's Prostatic Dominion: Chapter 1 - The Virgin's Binding

In the shadowed glow of the experimental clinic, Dr. Cellia loomed over the trembling 20-year-old virgin strapped to the gynecological chair, her emerald form radiating unyielding power. Her tail swayed like a predator's promise, the stinger glistening with natural lubricants. 'Well, well, my skittish little specimen,' she purred, voice sharp as a blade dipped in honey. 'Mark, is it? A virgin at twenty? How delightfully rare. Don't fret—I'm not here to devour you... yet. This is science, darling. Your prostatic fluid and fresh cum will fuel my reproductive experiment. Pure, potent, untouched. Resist, and I'll simply make it more... stimulating.'

Mark's eyes widened, sweat already beading on his brow as he tested the restraints. 'What the hell? You can't do this! I'm scared—let me go!' His voice cracked, but a traitorous heat stirred in his groin.

Cellia chuckled, circling him with predatory grace. 'Scared? How boring. Fear is just anticipation in disguise. My secretions will keep everything slick—no pain, only the occasional twinge of discomfort. Now, breathe. First, the prostate stimulation via your tight little ass. My tail's stinger will target it precisely, milking that gland until you're dripping and begging.' She leaned close, her breath hot. 'Then, once you're hard and throbbing, my tail expands into a perfect pussy to suck every drop of cum from that virgin cock. Witty enough for you?'

'You're insane,' Mark panted, his cock twitching involuntarily against the cool air. 'This is... wrong.'

'Wrong? Sweet boy, it's efficient. And you'll come harder than you ever dreamed.' With a flick of her wrist, her tail extended, the tip secreting warm, wet lubricant that dripped onto his exposed ass. She pressed the stinger gently against his entrance, circling teasingly. 'Relax that hole for me. Good... feel it slide in? No pain, just pressure building.'

The tail penetrated slowly, probing deep until it found his prostate. Mark gasped, body tensing but not hurting—only a strange, building fullness. 'Oh god... it's... weird,' he moaned, sweating profusely as Cellia worked it with expert thrusts.

'Weird? Try 'exquisite,'' she retorted wittily, her eyes gleaming. 'Your prostate is swelling nicely. Feel that? My secretions making you horny, wet inside. Pant for me, virgin. Let that cock get rock hard.' His member stiffened fully, pre-cum beading at the tip. She withdrew the stinger slightly, then drove it rhythmically, stimulating until his ass clenched and his cock jerked.

'It's coming... I can't hold it,' Mark panted, horny and overwhelmed.

'Exactly. Now the milking.' Her tail's end expanded, morphing into a slick, vaginal-like sheath that engulfed his throbbing cock completely. It pulsed and sucked, dripping with her fluids, combining prostate pressure with penile extraction. 'Feel my pussy-tail drain you? Cum for science, boy—explode that load.'

Mark's body arched as the dual stimulation peaked. 'Fuck... it's too much!' With a guttural cry, he came violently, thick ropes of cum pumping into her tail's depths, his prostate emptying in waves of intense release. Cellia smiled triumphantly, strong and dominant. 'That's it—every drop. But we're far from done, my absorbed pet. The real month-long harvest begins inside me.'
