You are gagged and stimulated.

BUZZZZZZZZZZZZZZZZZZZZZ!

The three of you yelp as your clitoral augments are activated at a high setting without warning. You moan helplessly unable to ease the intense buzzing within your clits. You have only been just secured in this **** position but your arms already ache. Your shoulders blades protest at how your arms are locked high behind your back.

Nurse Kelsey shoves her hand down the front of the small strip of your thong covering your womanhood. She quickly begins to stroke your buzzing clit and between your pussy folds. She continues, "Now, hun, the procedure sure is simple. We are going to go ahead and use our cloning technology to cause your breasts to rapidly grow! With a little supplemental hormonal and electrical stimulation, we are going to cause the cells of your breast to replicate. We'll carefully monitor and increase the amount of fat cells and mammary gland lobes to make sure you get a nice, even, perky set of tits! You'll even be able to produce more milk when pregnant!"

Nurse Kelsey briefly stops her fingering motion and pulls out a ball gag, "That's a good girl," she coos at you soothingly. She slides the ball gag under your panty and slides it up and down your pussy lips several times. She withdrawals the ball gag and holds it up to your face so you can see it is thoroughly coated with the juices of your arousal. Submissively, you open your mouth and accept the intrusion. A salty explosion hits your taste buds. She expertly closes the clasp of the ball gag behind you head and begins fingering your clit again. You try to focus on her words.

"We find a few orgasms prior to the procedure help the subjects relax," she further explains. "It also gets your nipples nice and hard! that's critical for the procedure!"

You nod appreciatively back at her and savor the flavor of your own sex filling your mouth. You look over at your trapped sisters and watch them suffering under the buzzing clitoris stimulation. Drool escapes around their ball gags that have been stuffed within their pouting mouths. Both Tess and Areli grind their hips in futility either trying to increase or hide from the vibrating sensation. Neither can be accomplished. Their breasts are vulnerably thrust out in front of them with their stiff nipples poking out from their peaks.

"Begin the next operation!" you hear the voice of the doctor cut across the large room. Immediately, nurse Kelsey and the other nurses and technicians leave the medical bays and disappear into the gloom beyond the spot light.

You look at your sister slaves one last time. You know that after this moment your bodies - no, your lives - will be changed forever!

Tess' eyes dart around in terror. Her whimpers are muffled behind her gag. Tears stream from her big brown eyes smearing her mascara down the sides of her face. The machine grips her long brown hair harshly forcing her to look straight ahead at you. Her toned muscles strain within the restraints. her B-cup breasts jiggle as she struggles and sobs within her ball gag.

She's weak, you think. She is only facing a two size increase. A B-cup to a D-cup!

You steal a look at Areli. She will be facing a much more **** change. Like you, her small A-cup breasts will be forever changed! The two of you will have the cells within your tits cloned and divided, increasing your mammary glands and fatty tissue beyond the limit of your small bodies. The results are sure to please your master... you have always fantasized about larger breasts, but F-cups will look comical on your petite frames.
