Chapter 1

Maria's glossy red lips slide up and down your shaft with practiced precision, her blonde ponytail bobbing rhythmically as she works. Her perfectly sculpted D-cup breasts strain against the thin fabric of her low-cut blouse, nipples visibly hard through the material. She pulls back with a wet pop, a string of saliva connecting her plump lips to your glistening cock.

"Dr. Stern," she purrs, her hand still stroking you firmly, "I should remind you that Giorgia Valentini has been referred for an appointment with you." Maria's blue eyes look up at you with devoted adoration as she licks a drop of pre-cum from the tip. "Her file is on your desk. Quite the overachiever, that one."

You glance at the manila folder while Maria returns to her oral ministrations. The wet, slurping sounds fill your office as you flip through Giorgia's impressive academic record. Full-ride sports scholarship, dean's list every semester, captain of the women's volleyball team. The file includes a recent photograph - Giorgia is strikingly beautiful with athletic curves, olive skin, and determined eyes that speak of ambition and discipline.

"Her sister Isabella is the real genius though," Maria mumbles between strokes, her warm breath teasing your sensitive skin. "Physics prodigy, Rhodes scholar, multiple published papers as an undergraduate. No social life. Complete opposite of Giorgia in personality. I hear the Physics department is already readying a position for her even before she graduates." She takes you deep again, her throat constricting around you as she swallows.

The sisters intrigue you. Such accomplished young women, each exceptional in their own way - perfect candidates for your special brand of ‘guidance’. You imagine Giorgia's confident demeanor crumbling as a new bimbo persona takes hold, her athletic discipline giving way to vapid self-obsession. And Isabella - transforming that brilliant mind into something concerned only with pleasure and appearance. So delicious.

Maria moans around your cock as if sensing your darkening thoughts, the vibrations pushing you closer to climax.

You grip Maria's blonde ponytail tighter, guiding her rhythm. "Schedule Giorgia for later this week. I want to meet with Isabella first—tomorrow if possible."

Maria pulls back, a thin strand of saliva connecting her swollen lips to your cock. Her mascara has started to run slightly, giving her a deliciously debauched appearance.

Maria moans her pretty mouth around your length, the vibrations sending waves of pleasure through you. Her technique is flawless—a testament to your work. You feel her throat constrict as she takes you deeper, her nose pressing against your abdomen. The wet, obscene sounds of her efforts fill the office as you reach for the file again, studying the photographs more carefully. You look through the supplementary files. Isabella will make a perfect opening.

Your climax builds quickly under Maria's expert ministrations. You grip her head with both hands, holding her in place as you empty yourself down her throat. She swallows dutifully, not spilling a drop, her eyes watering slightly as she gasps for breath when you finally release her.

Maria wipes her mouth with the back of her hand and reaches for her phone, her breasts heaving as she catches her breath.

As Maria makes the call, putting on her professional secretary voice that betrays no hint of what she was doing moments ago, you lean back in your chair and begin formulating your approach. The athletic, disciplined Giorgia will require a different technique than her brilliant, introverted sister. You'll need to establish trust first, find their vulnerabilities, their desires, their fears.

Maria ends the call and turns to you, her lipstick smudged despite her attempts to fix it. "Will there be anything else, Dr. Stern?"

You smile, already imagining the sisters transformed, their exceptional minds and bodies reduced to vapid vessels for the personas you'll create. "That will be all for now, Maria. Send Isabella in as soon as she arrives tomorrow."
