Mr. Black made casual inquiries around the school, trying to find participants for his next experiment. He made note of who seemed interested in the subject of natural instinct, with emphasis on who he thought would be able to handle the sometimes intense experiences. How the participants handled the experience was sometimes a surprise though—certainly Mrs. Higgs from the library was a surprise, her animal side rearing up as she took four huge young cocks one sunny afternoon.
In the dining hall one day Mr. Black noticed someone new. Mrs. Gardener was a visiting nurse, working with the school's staff nurse for a few weeks to help out with some testing. He approached her with his usual questions and immediately offered her a chance to partake in one of his experiments.
"Natural instinct?" she asked. "You can't give me any more to go on than that?"
"I'm afraid not Nurse Gardener," Mr. Black said. "For the observations to be useful the subjects need to be unaware of what might happen."
"Very mysterious," Nurse Gardener said. "In school I enjoyed the science, so sure, I'm game."
"Excellent," Mr. Black said. "One o'clock on Friday then."
———————
Friday at five minutes after one Nurse Gardener was sitting opposite Mr. Black's desk signing the confidentiality agreement, along with an electrician from the school's maintenance staff named Mr. Wilks. His muscular, wide-shouldered body barely fit in the small chair, and the light streaming in the big windows glinted off his shaved head. He seemed to ooze testosterone from his smooth, dark brown skin.
"I've signed one as well, as you can see," Mr. Black said. "We shall all disrobe now, and Nurse Gardener, when we're ready I'll have you tie Mr. Wilks and me up on the floor over there."
"Whoa, whoa, wait a minute!" Nurse Gardener said. "Is this some kind of a joke?"
Mr. Wilks looked very unsure of the situation as well.
"I assure you Nurse Gardener, this is no joke," Mr. Black said. "You're free to leave at any time if you feel uncomfortable. You too Mr. Wilks. If you wish to get out of the restraints just say the word and I'll have Nurse Gardener release you."
As Mr. Black was talking he was removing his clothes and folding them over his desk chair. Nurse Gardener watched as his tall, well-toned ebony body revealed itself, and before she could gather her thoughts he was naked, his massive cock hanging flaccid between his legs.
Mr. Wilks had started on his shirt buttons, glancing at Nurse Gardener nervously as he took it off.
"Nurse Gardener, please tell me now if you're unwilling to go through with the experiment," Mr. Black said in his quietly booming voice.
"I'm tying
you
up, not the other way around, right?" she asked.
"That's correct Nurse Gardener," Mr. Black said. "You'll be in complete control."
"You know I'm married right," she said. "I got kids and grandchildren."
"Yes Nurse Gardener, that was part of our interview," he said.
"So what are you testing, my willpower or something?" she asked.
There's a recording machine running, and I'll be asking you a series of questions," he said
"Hmm. I guess...I can do it," she said. "This'll be an interesting one to tell my husband."
"I'm afraid you can't do that Nurse Gardener," he said. "The confidentiality agreement. No one can know anything about these experiments for as long as they're underway, and after they're complete there will be no names or descriptors associated with the published findings. Your participation here will be totally anonymous, like it never happened. Is that acceptable to you?"
Nurse Gardener was in deep thought. Of course Mr. Black's experiment had started the moment he mentioned the word 'disrobe'. The reaction of his subjects, and their questions, was all part of what he was studying. How would a 'person off the street' react to a potentially sexual situation? Would their animal instincts override their common sense, their sense of right and wrong? Their religion? Their upbringing? Was animal instinct enough to break a marriage vow, and what was the thought process behind it?
"Are we continuing Nurse Gardener?" Mr. Black asked.
"Yes," she said. "For the good of science I guess, right?"
She suddenly looked nervous and made no move to disrobe. Mr. Wilks continued his slow undressing and was soon down to his worn-out looking white briefs. There was a fairly massive bulge in the front of them, and when they came off Nurse Gardener was astonished to she it came from a penis that wasn't even hard.
"Nurse Gardener, as soon as you disrobe I'll have you tie us up," Mr. Black said. "I'll begin the questioning now. Describe your feelings please."
"My feelings?" she said as started to lift the hem of her top up, exposing her nearly flat belly. "What the fuck have I got myself into, that's one feeling."
She was wearing nurses scrubs—simple, thin cotton garments that were easily removed. The top went over her head and her short Raven hair settled in a shiny, slightly messed up mass. Her brown eyes flared nervously as she stood there in her nice looking everyday bra.
"What would my husband think of me tying up two naked black men, that's another feeling," she said. "For that matter, what do
I
