"Oh god," groaned Innocence. She could feel the fat object lodged in her sex and shook her head in disbelief that all of this was happening to her.
"The next one does the same thing as the last one. We'll always use just one or the other but we might as well calibrate them both at the same time." Susan then turned a crank and Cency's legs separated further and lifted.
Innocence yelped again as she felt another hard object pressing against her little sphincter. "Oh god, no not there!"
"Relax dear," commented Dr. Grimm. "I lubricated it. And it's much narrower than the other one." She pushed and was met with some initial resistance. But quickly, the little sphincter yielded and the cylinder was pushed into Cency's rectum.
"Oh god," Innocence groaned again. She could feel every inch of the tube's invasion of her body and again she shook her head in disbelief. Finally, it was fully lodged inside of her and the professor gave the student's breast another reassuring squeeze.
"One last sensor and then we're done," said Susan. "This one might sting a little."
Cency's eyes flew wide open again as she felt Dr. Grimm's fingers at her sex again. She looked down across her body in horror as she saw the professor gripping her clit and tugging on it. "Dr. Grimm!!!"
"Just a second," Susan replied. Then she produced a clamp identical to the ones that were punishing the girl's nipples. She flicked the vulnerable clit several times and then attached the clamp to the tender little bud, causing Innocence to howl in pain.
"There we go," said Dr. Grimm, looking up at Innocence again. "What was it you wanted to say?"
"Oh god," groaned Innocence. "Ohmigod!!!"
"Well, you just lie there until you remember," Susan said. "We'll start to take the readings and do the calculations. Try to relax and, whatever you do, don't move. We are taking these readings at rest."
Innocence groaned again. How could she relax? She had three burning points of pain. And she felt her pussy and ass stuffed full. Then she felt the professor tugging on her pubic hair.
"This might have to go. Let's see if it interferes with the sensors first, though." Susan was resting her hand on Cency's belly, rubbing in slow circles until she slid her hand down to stroke her fingers across the girl's pubic hair. "Let me go check the data."
Dr. Grimm returned to her desk and busied herself at the computer. Innocence watched her type a few things on the keyboard and then check her monitor again. This was repeated about a dozen times and then the professor stood up again.
"Okay, the sensors we will be using are calibrated now. Let me just take off the taped ones." She started pulling off the little pieces of tape and setting them on the table that was beside Cency's chair.
"Couldn't you remove the other ones instead?" asked Innocence. "Especially the ones inside of me?"
"Oh, no," responded the professor. "Those are the most important ones. You'll always be wearing at least one of those each time we go into the field. Not only do they monitor your body but they're also the wireless receiver for these." She illustrated what ‘these' were by flicking one of the red balls attached to Cency's nipples, causing Innocence to howl as fresh pain shot through her body.
After Innocence had lain in the chair for an hour, she was told to stand in the center of the room. Susan admired the beautiful body for another full hour and made notes on ways she would explore and enjoy it. Then she had Innocence get dressed and go on about her day. She went about her normal day with the three clamps and two plugs in place and returned at the end of the day to have them removed.
Chapter 13
"Brilliant!" admired Richard when she described the events of the day to her husband over dinner. "She's such a genius when it comes to her research. I never would have thought about the embedded wireless receiver."
"It was pretty embarrassing," admitted Innocence. "And she says I'll always be wearing one of them for the field research."
"Brilliant," Richard replied. What he didn't say was why he thought it was brilliant. But he realized that having two different plugs would allow Susan to make either Cency's ass or her pussy available for play at the domination and submission events. And she would still be able to collect her data.
He had been in meetings all day so he had not had a chance to watch the "research preparation." Tomorrow, he would watch the live feed of his colleague molesting and toying with his wife.
The following day found a naked Innocence in the chair again with her feet in the stirrups. Her nipples and clit were once again clamped and her pussy and ass were stuffed with the two devices. After the hour of taking readings at rest, Susan walked to the chair and removed the clamp on the girl's clit.
"We're going to have to get rid of this little bush, Cency. It's interfering with some of the sensors." That was a lie but she knew that Innocence would never realize it. The truth was that she just wanted a sleeker and more erotic looking slavegirl to enjoy and to display at the events.
She produced the shaving cream and slowly rubbed it into the little patch of hair, letting her fingers glide lower to travel over the slick petals. Then she picked up the razor and scraped it over the girl's mound over and over again until it was completely denuded. She wiped off the remaining foam and then returned to her computer.
"Oh, we have some slight arousal measurements," said Dr. Grimm as she returned to Cency's side. In truth, there were significant arousal indications showing on the screen. "I want to get a full arousal measurement so we can continue to calibrate the devices."
"Full arousal?" asked Innocence. "How do we do that?"
"Leave it to me, dear," said the professor. "I'll do all of the work on this one. You just try to concentrate."
Innocence gasped as she watched the professor reach between her thighs and then groaned as Susan's fingers found Cency's clit. Innocence closed her eyes in shame as the fingers stroked her so intimately.
Susan was loving the sight before her. The naked girl was blushing beautifully. Her body kept tensing as the fingers explored and experimented, causing the delicious breasts to quiver and quake. Soon, the belly was quivering also and, within a couple of minutes of play, the beautiful slavegirl was climaxing. It was the perfect orgasm as far as Susan was concerned.
"Oh god," stammered Innocence after she recovered. "I'm so sorry. I can't believe that just happened."
"It happened because I made it happen, girl," replied Dr. Grimm. "It was necessary to continue to calibrate the instruments."
Innocence blushed at being called girl. She probably would have expected that during the field phase of the research when she was in role as a submissive, but not in the hallowed halls of academia. Maybe she should say something about it to the professor so that she didn't make that mistake again.
Dr. Grimm was at her desk, pecking away at her computer and checking her monitor. Frequently, she entered a few more keystrokes and then would return to the chair that held Innocence.
"I made a few adjustments," Susan announced. "We need to do it again to check the calibration."
Innocence gasped. "Again? Again what? Another orgasm?"
"Exactly," nodded Dr. Grimm. "I'll do all of the work again. Just lie back and try not to get distracted."
"Ohmigod!!!" groaned Innocence as she saw the professor's hand returning between her thighs.
Dr. Grimm stroked the satiny, wet folds several times, enjoying the feel of the girl. She couldn't believe that Richard had volunteered his wife for this particular research project. Surely he must know that Innocence would be treated as a slave by her. And surely he must recognize that Innocence would be used sexually by her and by others who she designated. What husband would permit that?
