Nibbling fish? (Fun, weird)

The three of you yelp as the restraining machines of the medical bays whirl to life around you! Your arms are pulled higher behind your backs forcing you to bend forward on your knees. Your hair is pulled roughly behind you causing you to look forward at each other. Your sister concubines look so ****. The restraining contraption pulls your arms high behind your backs. Tess' B-cups hang below her. You and Areli thrust your A-cups out with less effect.

The machines whirl and maneuver two bowl shaped containers beneath each breast. They are clear, brightly lit, and filled with fluid. Inside you can see small fish swimming. You catch looks of puzzlement from your sisters. You share in their confusion. Two tiny fish slowly swim in circles within each of the containers below Tess. Five swim within each container beneath you and Areli.

"Hey huns!!!!" Nurse Kelsey's voice cuts in via speaker, "We were able to get these Sakana o kajiru from the neighboring Shigaraki kingdom..."

At hearing your native tongue your heart floods with emotion. Shigaraki was your homeland. These Sakana o kajiru were gifts from your father to your new Master. Sakana o kajiru roughly translates to Nibbling fish.

"... they are the cutest aren't they, huns?" Nurse Kelsey continues, "These little cuties have a bioengineered toxin that causes breast tissue to replicate. Properly applied it should cause your breast tissue to divide and grow. You'll get more nerves, milk lobules, fat and even stronger cooper's ligaments. All things considered you should have some great big tits!"

Tess begins to thrash in fear at the word toxin.

zzzzzzzzzzzzZZZzZZZZZZZZZZZ... Crackle!

Her clitoral augment stops vibrating and sends a punishing shock through her pussy. She spasms for a few moments before relaxing into her restraints. The buzzing resumes between her legs matching your own vibrating torment.

"Now now!" Nurse Kelsey chastises, "Don't struggle. It shouldn't hurt too much. Mostly tickle!"

Tess' big brown eyes look around at the gloom beyond the spotlights shining down on the three of you. She pleads wordlessly into her ball gag, but she does not struggle after her punishment.

The Machines holding the three of you whirl too life and all of your breasts are dipped into the containers!
