"Oh posh," declared Susan. "My girl can handle anything." She pushed the dildo especially deep, causing Innocence to yelp as fresh pain shot through her belly.
"How did it make you feel to know that his wife was watching you make love to her husband on the stage? Susan continued.
"It was very embarrassing, Mistress. But I did not really consider it making love. He was being forced to fuck me. But I was still embarrassed. His wife must have been horrified to see her husband fucking another woman."
"She didn't seem too horrified," replied Dr. Grimm. "I had her sitting in my lap and she climaxed twice during the auction. Once was when Tom was fucking you."
"Wow," gasped Innocence. "I'm surprised."
"You see, little one? You are not alone. Others find comfort in surrendering themselves to others. You have many slave sisters out there. And brothers, too."
Susan realized she needed to make modifications in the office. Currently, the only way to monitor Cency's sensors was to be at her computer at her desk. She made a mental note to put another monitor near the chair where much of the research was done. She could put it on the counter behind the chair so she could see it but her favorite research subject could not. She needed to have a way of getting Cency close to climax but to know when to back off before climax.
"Do you remember the last thing that the auctioneer did before you were sold, little one?"
"No, Mistress. Wait!!! Yes, Mistress. He made me cum?"
Susan reached for the table behind Innocence and picked up the cane. "Yes, girl," she said as she showed Innocence the cruel instrument. "He made you cum with this. And now I will too."
"Mistress, Mistress, Mistress!!!" cried out Innocence. "No!!! Wait!!! Please!!!"
Susan saw the look of panic in the girl's face. She couldn't wait to see what the sensors were recording. The dildo kept moving in and out of the girl's sex as she raised the cane. Cency's eyes were opened wide in horror. She struggled in her bindings but could not escape from the inevitable punishment she was about to endure.
THWACK!!! Dr. Grim brought the cane down swiftly across the upper swells of Cency's breasts. The auctioneer had struck the girl across the nipples and Susan would have preferred to duplicate his actions. But the nipples were currently clamped with the sensors. She could not afford to disturb them.
Cency cried out from the pain as it felt like her breasts were being sliced off of her chest. Her body tensed and then convulsed as the orgasm swept through her body. Susan kept moving the dildo in and out, letting it bang against the girl's cervix with each plunge. Innocence gasped with each stroke and her orgasm continued to mount.
Eventually, Susan slowed the dildo and then pulled it out of her research subject. "Remarkable," she uttered.
She could not wait to get back to her desk to see the data. She looked down and kissed Innocence on the lips, hearing the girl moan into the kiss. She traced her finger along the angry red line that now adorned the girl's chest, causing Innocence to shudder again. She smiled and then kissed her pet again.
After Innocence recovered, Susan spoke again. "I have good news, pet. We have more field research on Saturday night."
Innocence tensed at the news. "Oh no! You aren't going to sell me again are you, Mistress?"
"I might," smiled Susan. "We'll have to see. But remember that it's my decision; not yours. I own this delicious little body."
Chapter 20
"It's really remarkable," said Dr. Grimm as she was sitting in Richard's office. "Her arousal readings went off the chart and she climaxed as soon as the cane came struck her breasts. With most people, the readings would have gone way down with the blow."
"Hmmm," said Dr. Blackwell as he rubbed his chin. "That is surprising. But how do you know that it would go down in most people?"
"Anecdotal evidence is all I have," replied Susan. "But I have seen women lose their arousal when pain is applied. I have seen men lose their erections from a whipping or paddling. I'm not sure that any studies have been done but I'm sure that arousal is usually reduced from pain."
"Maybe that's something that you should study," offered Richard. "Some solid academic work on the topic would be very enlightening."
That night, Susan designed a research project to examine the influence of pain on arousal. It would initially just be a small sample of five females and five males. She was sure she would get volunteers from the university once she posted the notice.
Cency's eyes were wide the next day as she read the research plan. "Dr. Grimm… I mean Mistress. Who in their right mind would volunteer for this? I mean who would willingly accept pain?"
"Well, dear," replied Susan. "They won't exactly be volunteers. There will be a small stipend for each of them. And a lot of people will do things that they don't want to for money. Plus they won't see the entire research plan. All that they will know is that we are doing arousal research."
"Wow!" said Innocence. "I sure hope it's a big stipend. When do we start the study?"
"Hopefully in two weeks," Susan said. "I'll post the notice today. We can screen candidates next week and begin the following week."
"She's brilliant," Richard smiled brightly that evening over dinner with Innocence. "I love her research design. Her screening tool is very well thought out. And her method of arousing the subject is sure fire and economical."
"She didn't tell me how she planned to screen candidates."
"It's pretty simple. No virgins and nobody who has been into the domination and submission scene." Richard laughed. "Poor Katy. She won't be able to earn a few bucks on this one."
"Oh, that makes sense," nodded Innocence. "And how is she going to arouse them?"
"With you, pet," he grinned. "Or more accurately, with your lips and tongue."
"Oh god," groaned Innocence. She wondered if any other doctoral students ever had to go through the indignities that her research was dragging her through.
On Saturday night, Susan walked into the ballroom for the latest gathering of the domination and submission crowd. Richard decided that he should attend but when Susan called to make the reservations for the three of them, she learned that they would need an additional sub. Married couples could share a sub but unmarried couples each needed their own. Richard talked to Kaitlin and she agreed to go as the second sub. So now, Katy was tethered to Susan and Richard held Cency's leash. Dr. Grimm would have preferred to have Innocence so she could always be near for the purposes of the research project. But she also recognized that it would be awkward for a nearly naked Katy to be led around by her father.
Richard was certainly getting an eye full. Kaitlin was dressed in an outfit that was identical to Cency's. Both wore the sheer pantaloons and the tiny cropped vests. This was more of his daughter than he had ever seen and he marveled at how mature and magnificent her body was. And both girls soon became the center of attention in the big ballroom.
Displays lined the wall where stalls were filled with vendors offering bondage equipment and gear. They wandered down the row of little shops, looking at all of the merchandise. Innocence was the least interested in the goods. To her, they all just represented new ways of tormenting her.
Kaitlin was the most interested and she had to examine every device and machine that they encountered. "How do these work?" she asked, holding up two odd looking objects.
"Here," replied the woman at the stall. "I'll show you." Then she turned to Susan who was holding Kaitlin's leash. "May I?"
