Tentacles (aggressive)

A web of mechanical tentacles reach around from behind each of you. Each tentacle is capped with a large suction cup and snakes around your newly formed breasts searching for the nipples at their sensitive peaks. They latch forcibly causing all of you to scream into your gags! The insides of the cups are moist and form a tight suction around your sensitive buds. The three of you thrash within your restraints attempting to relieve the vacuum around your nipples. You look into the terrified eyes of the other girls sharing in their hopelessness. Tears stream down your faces.

"NIPPLE CAPTURE SUCCESSFUL. INITIATING STIMULATION" announces the familiar mechanical voice.

A mechanical roar emanating from a nearby pump masks the buzzing of your clitoral augments. Immediatly you feel the suction sensation increasing! Your little nipples are sucked deeper into the cup with an abrupt ****.

"Mrrmrrmrmrmmmmmmmmmmmmmmrmmrrmmph!" you moan into your ball gag.

The tentacles begin to move, pulling your swollen breasts by their nipples into constantly shifting directions. The new sore mammary flesh screams in protest within the painfully tight skin surrounding them. Your nipples strain as they bear the weight of your overfilled F-cups. Through your tears you can see your sister slaves suffering the same treatment. Tess' face is red with torment as her new D-cups are abused. Poor Areli appears to be suffering even worse as she adjusts to her own massive triple D's. She shakes within her restraints as another powerful orgasm overtakes her.

"CALIBRATION INITIATED. TESTING INITIAL SENSITIVITY."

The cups slowly spin back and forth causing your nipples to twist uncomfortably. The monitors at your stations immediately come alive displaying cross sections of your nipples and documenting various stats. Your own displays several hundred nerve endings operating within "normal" parameters. The three of your arousal levels progress as the tentacles continue to twist and manipulate you into higher and higher states of sensitivity.

"BASELINE ESTABLISHED. INITIATING NERVE CLUSTER CLONING."

Oh No. The three of you think.

Suddenly the tentacles go rigid and a deep light emits from the nipple cups. An energy field projects from the device into your trapped nipples. Your breath catches at the sensation and goosebumps cover your entire body. This unseen **** isn't painful but the sensation is intense enough to cause the heart beat of all three of you to skip at the same time.

On the screen you see the mapped network of nerve endings within each nipple begin to glow and divide. The number of nerve endings counted on the screen doubles! The tentacles twist uncomfortably causing you to stiffen at the situation. The number of nerve endings double again! Then again! Then Again!

"Mrrrrrrrrrrrrrrrrrrrrrghrrrrrrrrrrrghgrgh!" Areli growls. Drool escapes the gag and falls onto her brand new large breasts. You notice that her nipples are much puffier and larger than before within the translucent cups.

You fight against your restraints, painfully pulling against the robotic arm tugging at your hair, and attempt to look down at your own nipples. Yours have also grown in size to better fit your newly formed breasts! The monitor shows the number of nerve endings within them have increased to over a thousand.

I can't bare anymore!

The tentacles thrash and the cups light up again! Your nipples protest within their moist prisons as the number of nerve endings double again!

2,500 nerve count!

Tess snorts and sputters around her gag! More duplication occurs.

5,000 nerve count!

Areli's eyes roll back in her head. Her petite little body shakes as if rejecting the procedure. More duplication occurs.

10,000 nerve count!

The three of you shake in another powerful orgasm!

"SENSITIVITY INCREASE SUCCESSFUL!"
