I strongly suggest you read the earlier chapters of the series, as they provide important context about the characters and themes of the series.

With Lady Amber leading her by the hand over to her submissive client Nicole, Tara looked at me once again, with eyes begging me to rescue her. I knew I could not stop Lady Amber, or LA as I called her in my notes, given how I had submitted myself to her yesterday. I glanced away from Tara's terrified-looking eyes and busied myself in the notes on my laptop.
Tara started to say something to LA, but before she could get the first word out of her mouth, LA stopped and put a finger to her lips, mouthing a quiet, "Shh." Knowing that I would not protect her, and unable to resist herself, she gave in and allowed LA to continue to walk her over to her client. I looked up from my laptop screen, and when they reached the sofa, LA switched her hand from gripping Tara's to placing it gently on the back and guiding it to Nicole's wide ass. Still holding the back of it, she moved it along first one cheek, touching every square inch, and then the other. She repeated this, so that she had run her hand twice over each of Nicole's pink-marked hemispheres. She then lifted Tara's hand up and released it.
She walked to the front of the sofa where Nicole's head was, and reaching down, said, "Open." Nicole must have opened her mouth, as LA retrieved her panties and dropped them on the floor next to the sofa. "You're very well marked, my pet," LA said to Nicole. "Did the touching help soothe you?"
"Yes, Mistress Amber," the submissive responded, "thank you for easing my pain."
"Oh, it's not me you should be thanking," LA chuckled in response. "That was Tara who was helping soothe you."
I could not see the look on Nicole's face, with her head buried in the cushions of the sofa, but her body seemed to jerk in response to this news. "Yes, my little slut, Tara is participating in your debasement. Do you have a problem with that?"
"No, ma'am," she responded, without hesitation.
"Good, because you know when you are here for a session, I call all the shots and you'll do everything I say, won't you?"
"Yes, ma'am."
LA patted her gently on the head. "That's a good girl."
Tara again started to say something, and once again, LA put a finger to Tara's lips. She took Tara's hand, led her back to me, and bent down to quietly whisper in my ear - loud enough for Tara and me to hear, but not loud enough for Nicole to hear us. "I'd like you both to step outside with me for a minute."
I rose, placing my laptop on the chair, and joined LA and Tara as they headed for the door. LA did not say anything to her client, who I gathered was used to being left in the session room in the past while LA stepped out of the room.
We walked up the stairs, and LA closed the door behind us. LA asked Tara, "Are you interested in gaining some firsthand experience as part of your research, Tara?"
"I don't know," she responded, looking at me. "Would that be ethical?" she asked.
"Well, there is some tradition in psychology of participatory research," I responded. "It's somewhat rare, but not unheard of. I'm okay with it if you are."
Tara hesitated a few seconds before she said, "I was thinking about continuing this line of work in my own dissertation research, so maybe it would be helpful for me to get this kind of experience." Turning to me, she asked, "But shouldn't you be gaining this experience as well."
Before I could answer LA jumped in. "Oh, don't worry about her, Tara. She's older than you and I'm sure has had many more experiences than you have," she responded somewhat ambiguously, but with a sly smile on her lips.
I certainly didn't want this conversation to go any further, afraid that the topic of what LA did to me yesterday would come up, so I thought quickly on my feet and came up with another reason. "Besides, one of us needs to be taking notes, so I'll do that while you are participating."
With a shrug of her shoulders, Tara responded, "Alright, if you're both okay with it, I'm game. What do I need to do?"
"Great," LA said, clapping her hands. "You just follow my lead, and I'll guide you through everything. Do you promise to do that, and do everything I ask of you? I don't want to have any more interruptions in this session with Nicole."
Tara looked a little hesitant, but LA came over, put her arms around her and gave her a hug, patting the back of her head in a maternal fashion. "It will be just fine, sweetie, trust me - you'll enjoy it and I think you'll gain some great experience. You do trust me, don't you?" As she said this, she was looking over Tara's shoulder and right into my eyes, bringing back to me the memories of my session with LA yesterday. Another smile came to her lips, and she winked at me. I wasn't sure what she intended to do, but I felt that I could not call a halt to things at this point, and had to let her continue.
This must have been enough to convince Tara, because she pulled back, and said, "Okay, let's go." The three of us headed back down the stairs, LA first, followed by Tara, and then me. I went back to the chair, picked up my laptop, and sat down. Tara stood in the middle of the room, waiting her instructions.
"Okay, my pet, we're back after a little break. Are you ready to continue?"
"Yes, Mistress Amber," Nicole responded. She must have been very well trained by LA, as it appeared that she had not moved an inch during the time we were gone. She was still head down on the sofa, her large ass stuck up in the air and her large tits splayed out beneath her body, each nipple clamped with the chain running between the two.
LA walked back to the dresser, reached in to grab something, and headed back to the sofa. As she approached, I could see that she had in her hand what looked like a set of small balls that were centered on a thin, rigid plastic cord, along with a small bottle of something. I knew from my research that the balls were anal beads, as their size grew from small on one end to larger on the other. The largest appeared to be about the size of a ping pong ball, and just beyond that last bead the plastic cord ended in a large plastic ring about an inch and half in diameter. I surmised that the bottle in her other hand must have been some kind of lubricant. She handed both to Tara, who took them, and she returned to the dresser. She opened up a deep drawer at the bottom and took out a large towel. She came back to the sofa, and unfolding it, placed the towel between Nicole's spread legs so that it ran from about her knees up to where her breasts were flattened against the sofa cushion.
"Okay, slut, I'm going to be giving some instructions to Tara here, so she'll be participating in parts of the rest of the session." LA handed the bottle of lube to Tara. "Go ahead and drip some of this down her crack, sweetie." Tara looked a little surprised at this term of endearment, as was I, but she quickly took the lube, flipped open the top, and held it an inch or so above the top of Nicole's crack. She squeezed, and the liquid began to drip from the bottle, slowly at first, but with a slightly stronger stream as she applied more pressure. I watched the viscous liquid begin to run down her crack. It was quite thick, so it took a few seconds for it to reach her puckered asshole, pool there a bit, and then continue down past her perineum. A few drops stuck onto the bottom of Nicole's labia. Nicole's wide ass shook a little bit in reaction to this stimulation of her ass and labia. I could see her breathing was getting heavier, and took note of this on my laptop.
"That's enough," LA said, her voice waking me from my reverie. Tara recapped the lube, and put it on the coffee table next to where Nicole had put her clothes. "You want to make sure everything is well coated in there, so take your fingers and rub in the lube." Tara hesitated once again, I assume because she was unsure whether she could really do this. But she must have gotten her resolve up, because she took a finger and gently rubbed the lube around the crack. I could see everything very clearly, and it appeared that she was doing her best to avoid Nicole's rosebud and labia, however. When she finished, LA reached down, picked up Nicole's panties, and handed them to Tara with a smile. Tara took them, looking at LA quizzically. LA mimed wiping her hands, and Tara got it, and began using the panties to wipe the lube off of her hands. She placed the panties, now soaked with lube as well as Nicole's saliva and pussy juices, on the table.
LA took the anal beads and brushed them into Nicole's crack, running them up and down, and rotating them as she did so. I gathered that she was getting them lubed up as well. She then handed them by the ring to Tara. "Go ahead and begin guiding them in from the smallest bead first, sweetie."
Tara got closer to Nicole. She began to do what LA had commanded, but before she got the first bead near to Nicole's rosebud, she stopped. "I don't know if I can. . .," she started.
But before she could get anymore out, LA interrupted her. "Go ahead," she said in a stern, commanding voice. "You agreed to do everything I said, didn't you?" Tara meekly nodded her head up and down. "Besides, she's such a slut that she loves having things shoved up her ass." She patted Nicole's back a couple of times. "Don't you, my pet?"
