Biochemical Convergence
Jill and Mitch decided to actively study the mechanisms that the medallion used. Even though it defied physical reality, or man's current understanding of reality, Jill wanted to study it logically. To start, she decided to research any physiological effects it had on the human body. She approached a biochemistry major acquaintance of hers for ideas.
Karen was a senior honors student in biochemistry working on two minors, psychology and mathematics. She had offers to attend graduate school a several universities, although she was considering med school. She was working on campus in one of the labs, working in animal models of endocrine effects of stimulant drugs. She spent her lab hours drugging mice, metering their food, weighing them, observing their behaviour, that sort of thing. Boring stuff really, unless you are into that kind of thing.
Jill asked her to lunch one day to probe her for ideas, "I was wondering if you knew anything about human hormones and their possible effects on other individuals."
"You mean like pheromones?"
"Ya, that's the word I meant. Is there any research on how one individual can induce significant changes in those around them."
Karen got excited. She loved talking about this stuff. So often people got sidetracked by her looks and expected her to only care about simpler things. They'd see her big tits and assume she was a bimbo. "Well, there are certainly strong effects known in lower animals. Queen bees developing from regular worker eggs by being fed royal jelly. Male flies swarming around an egg laying female. A hundred snakes in a writhing ball having group sex. The effects get less and less defined as you go up the tree of life. In humans there are only tiny effects demonstrated, mostly limited to preferences and feelings. There are no studies showing anything as complex as overt behavioural changes."
The bait was being taken. Jill began to reel her in, "My boyfriend says he 'has this effect' on people. Girls especially, says he can control girls. I'm sure it's juvenile boasting. I was wondering if you could devise some experiment that I could pull on him. Something that would prove to him that he's full of shit. In a joking way."
"You want to pull a prank? Oh, that would be funny. Count me in. We would have to set it up so it seems like a casual, chance happening."
They arranged to meet at the student center cafeteria the next day. Karen would be at a table and Jill would bring Mitch by to show off his 'tricks'. Karen would play along, long enough to pull off a good joke.

Karen picked out a table near the west windows, one easily seen from the main entrance. As agreed, she was wearing something a bit sexy, revealing, just for fun. It was Friday afternoon. She'd go out to party after this prank was complete. She waved across the dining hall, making sure they saw her. She sized up Mitch and liked what she saw; tall, blond hair, blue eyes, the same blue as Jill's, fit and muscular looking, symmetrical facial features.
The joke wasn't on Mitch, though. It was a trap for Karen. Jill had picked her out as an excellent next slave for her owner; smart, attractive, healthy. And holy shit, what a body! Mitch didn't need any help picking out his slaves. He let Jill make the choice because he wanted to see how far Jill's ownership link would go. Would she make a choice with his interests in mind? Or would she let some vestige of her own preferences show?
They sat down with Karen and exchanged pleasant introductions. Mitch allowed himself to leer at Karen. She was absolutely stunning. Lush brunette hair, fetching eyes, delicate nose, straight teeth. She was sitting down so he could not fully evaluate her figure. The low cut blouse showed off a well developed cleavage, though.
Mitch was definitely pleased, "Well done, Jill. I knew you'd pick well, but this one's fucking awesome! Karen I'm going to enjoy taking you home and fucking your brains out."
Karen had been expecting a bit more banter. Mitch had gotten rude and crude right off the bat. Disturbed by his obscene comments she was about to call the whole thing off when Mitch continued.
"Ypi̱réti̱s (Servant). Stand up so I can see your body better."
Karen decided she would play along. She stood and did a slow pirouette. She knew she had an outstanding figure, blessed by birth and honed by regular hours in the gym. Large tits, flat strong stomach, rounded ass, long muscular legs made longer by high heels. She preferred to be appreciated for her brains. But it wouldn't hurt to show off a little for Jill's boyfriend. She felt her skin flush warm and her pussy swell, thinking, 'This kind of fun, showing off for this guy. Let's see how far this can go.'
Mitch had decided he would keep Karen in servant mode before fully enslaving her. However, he found himself having less and less patience for gender games. It seemed too much like seduction to him, a game he never had much luck at, "You look great Karen. You need to fully understand the predicament you find yourself in. Go to the ladies room, choose a stall, and take all your clothes off. Everything except your heels. No matter who else is there, step out to a mirror and take a long look at yourself. Cup your breasts and turn around. Look at yourself for a full minute. Admire the body I will be fucking tonight. Put your clothes back on but leave your bra and panties off. Carry them back here to the table... Go!"
Karen did exactly as instructed, amazed that she could not stop herself, amazed at how calmly obedient she was being. There was one other woman in the restroom. While Karen stood looking over her own spectacular figure, turning to the side to get a profile of her ass, the other woman flushed and left her stall. She stopped in her tracks when she saw a naked woman, obviously checking herself out. The other woman skipped washing her hands and left in a hurry.
When Karen returned to the table, undies in hand, she was no longer thinking that Mitch was boasting. "What did you just do? how did you do that? I couldn't help but do exactly what you told me! It should have been embarrassing. Instead, that was fun!"
"Put your panties on the table and sit down, Karen. For now, I have taken control of you. As to how I do it, we're not completely sure, Jill and I. We want you to use your lab skills and education to see if you can figure out what is happening. One thing you can count on, I will be fucking you tonight. You and Jill both, I'll fuck both of you and you will fuck both of us. You are sexy, I want you, that's all the justification I need."
"I don't want you to abandon your car here at campus, so go home to shower and shave, redo your makeup, then pack a few things for the weekend. Bring your bathroom gear and any other personal items you need. You won't need to pack any extra clothing other that what you arrive in. You are to meet at my apartment in three hours. Spend any extra time before leaving on your bed with a hand mirror watching yourself masturbate. Just before you leave dress in the shortest mini skirt you own and your highest heels. No panties, no stockings or jewelry. Show up on my doorstep nearly naked and ready to fuck."
With that, Mitch stood to leave. Jill quickly wrote down their address for Karen and hurried to catch up with Mitch.

Karen calmly did as instructed. Masturbating for an hour and a half was neither boring nor tiresome. She had developed sexually long before her parents had allowed her to date. She had learned to masturbate early on and self-pleasured nearly daily during her entire development into a woman. She dressed, adding a skimpy bikini top to the mix. It felt fairly wicked driving to Mitch's in her tiny mini skirt without panties. She continued to reflect on how Mitch had been so blunt on his intentions, how cooperative she was being, and how she wasn't angry at Jill for setting her up like this. Following his orders seemed as natural as breathing air. Disobedience was impossible to even consider. Right before knocking on their door, she reached up her skirt, slipping her middle two fingers in to make sure she was complying with his instructions, recalling them from memory, "Show up on my doorstep nearly naked and ready to fuck." Yes, very ready to fuck. Now for the nearly naked part. She untied the bikini top, pulled it off, and knocked on the door.
Jill answered in the nude. Karen didn't have to ask why. Her hair was a wreck. She was drenched in sweat. And her labia were swollen and pink from rigorous sex. Jill led her to the couch where Mitch was waiting, erect. Without saying a word, he held up a hand, motioning for for her pause and present her figure for inspection. She stood proud and upright, pulling her shoulders back. Her eyes twinkled and her wide smile showed off her perfect teeth. The middle finger on her right hand found her clitoris and stroked softly, slowly.
Mitch leered at her from head to foot, pleased with what he saw. His gaze lingered on her spectacular tits, her nice round ass minimally covered with a tiny skirt, and her curvy legs made to seem longer on high heels. Karen had chosen a tight fitting spandex skirt in bright red. It hugged and accented her awesome ass. The hemline had worked its way up her hips which exposed her lower lips to causal view. He signaled his approval by waving her to take up residence on his lap. Karen straddled him and settled her weight down as Jill guided his cock. No foreplay, no verbal banter, not even a hint of hesitation from Karen.
