At twenty one years of age, Carla and Grace were in college, studying a combination of biology and electronics. Being way ahead of their class, the two females worked together in writing many research papers, showing the true mark of genius.

However, despite their brains, things didn’t always work out financially. Knowing they’ll land a secure position after graduation, they nevertheless needed money to pay their bills and rent, for both were leasing an apartment off campus.

By providing sexual favors for men, the two college girls solved their finical problems, functioning as professional dominatrixes. Having dominant personalities, this profession wasn’t just something they did for money, they simply loved to be in control. The idea and action of whipping a man would turn Carla and Grace on, with sexual excitement penetrating every aspect of their being. Making a man cry and beg for mercy was something both were good at. Acting as a bitch is a noble task, and they both knew every detail of the great art.

Each dominant mistress had a male friend whom she bossed around. Not having the intelligence of the two ladies, Max and Ralph nevertheless liked the women and looked up to them. Carla in particular loved to torment her boyfriend Max, dominating him sexually, striking him with the whip, and liking every minute of it. Going further with humiliation, Carla would tie him all up, light up a cigarette, and begin burning Max until he screamed and begged for mercy. The lowder he yelled, the greater her sexual desire to torture and cause pain. Truly, sexual sadism was one of her greatest talents.

Grace, on the other hand, was more into toilet humiliation, humiliating her boyfriend Ralph by having him lick her ass clean after she took a shit. After having her behind cleaned, the sadistic cunt would always turn around and spit into his face. Incapable of breaking the hypnotic hold she had over him, Ralph took it all without complaint.

Further, even when they weren’t out performing domination action for men who paid them, their attire was always of a fetish nature. The vixens always wore black leather knee-high stiletto boots which stimulated their sexual cravings, making them feel powerful. Also, under her regular clothes, each wore a black leather waist corset, liking the the tight and straight sensation it produced. If any one of the two received a call, she would immediately go right after class and perform the session. Having all of her equipment in the trunk of their car, each cruel bitch posessed a whip, long leather gloves, and a few other utensils used to torture and strike.

At times, the dominant women would bring their boyfriends to the apartment, making the males clean up the place. Everything had to be perfect. If an item was out of place, one or both of the ladies began striking the boys until they responded as the females desired.

Being as all may, Grace was already home early one Thursday afternoon when Carla entered the flat. Looking all excited, she yelled to Grace, “ I think I found something; I could be wrong, but I don’t think so!”

“ What is it?”, responded Grace.

Still excited, Carla said, “ Remember that project we were working on last week; the one where we tried to affect the growth of any living being; well it appears the experiments are yielding some results!”

Calmly, Grace inquired, “ What kind of results?”

“ It appears as if biological organisms can have their growth and development processes reversed.”

Becoming intensely interested, Grace ask, “ What about the speed this takes place?” “

“That’s the whole problem.”, Carla replied, “ The rate’s very slow; however, I think I can make it go faster in the next few months if I get your help.”

Quickly, Grace said, “ You’ve got it.”

Next, Carla suggested, “ Why don’t we return now to the university and look at what I’ve found.”

Leaving the apartment, both she devils went down to their car. Getting into the black mustang, they drove to the school. Parking the vehicle next to the science building, Carla turned off the ignition, and they both got out. Grace and her friend walked into the complex, entering the lab. Going straight to the spot where they had their own little experiment place, the two gothic dominas sat their asses down and studied the results. Carla showed Grace all she had seen earlier that afternoon. Intrigued, Grace said, “ Interesting, how do you suggest we go about increasing the rate of reduction?” After hearing many suggestions, Grace began adding points of her own. Working late into the night, it wasn’t until the small hours when the two evil ladies returned home.

Going back to the university the next morning, they sat through their regular classes. When the lectures were finished, the felines returned to the lab and continued working, again staying late into the night before driving back home.

As time continued, the dominatrixes spent more and more days of the week in the lab working away. Eventually spending almost every evening in the research room, the two women neglected their boyfriends, not speaking with the males for weeks.

With the passage of another month, the two finally got the process working, being able to reduce any living thing to a fraction of its original size in only a minute’s time. The result pleased the women greatly. In a few days, the two femme fatales perfected a shrink ray that emanated from a small pistol. In other words, they built a shrink gun. Pointing it at anyone and pulling the trigger, the females could now shrink any person to only a few inches in height! Obviously, this invention elated and stimulated the darker impulses within the two mistresses.

Taking the devise home, Carla then said to Grace, “ Well, let’s try it out on someone; just think of all the fun we’d get when torturing a three inch high man!”

Starting to smile wickedly, Grace replied, “ Yea, let’s shrink Max and Ralph!”

“Great idea.” responded Carla.

Next, reaching for the phone, Grace called Ralph. Hearing the phone ring at his place, Ralph answered, “ Hi, who is this?”

“ Hi, its me; sorry we couldn’t spend more time with you two guys, but we were very busy; how would you like to come over today with Max?”

Happily, Ralph responded, “ Yea, thanks; I’ll call Max and we’ll both be over.”

Giggling, Grace said to Carla, “ It worked; we’ll really have a great time this afternoon!”

With the phone hung up, the evil bitches removed all their clothes except for the boots and corsets.
