-------------------------------
I awoke Monday morning feeling like the huge weight that had settled on me over the weekend was suddenly lifted. It was as if the cloud of nagging doubts that had been growing over the weeks since I took control of Adrienne were suddenly cleared away, and I was free to continue the use of my little slut completely unfettered by any long-term commitment on my part. She may not have preferred it that way, but if she was willing to just take whatever I gave her, who was I to argue?
I phoned Nikki to let her know I'd be in the office a little late and asked her to please inform Adrienne that I would have to reschedule our meeting to eleven o'clock. Five minutes later I got a text from Adrienne on my cell phone, "What meeting?" I sent back an ambiguous, "You'll see."
I called Adrienne's office just after leaving the local adult toyshop, where I'd stopped to pick up a gift for her, but Nikki answered, explaining that Adrienne was on a teleconference with a client. When I asked whether she'd be available for our rescheduled meeting, Nikki assured me that Adrienne would be free by then. But when I arrived at her office, Adrienne was still on the call, so I took a seat across from Nikki's desk, in the executive office waiting area.
"I'm sorry, Jason," Nikki apologized, "I really thought she'd wrap things up with the DyNet folks by now."
"No problem," I answered sincerely, "If you don't mind me waiting here for her to finish."
"Of course," she smiled. "Would you like me to let her know you're waiting?" It was a knowing smile, the kind of smile that says, "I know more than you think I know." And I wondered to myself if she'd begun to suspect something was going on between Adrienne and me. I thought we'd been very careful so far, but maybe I missed something. Or maybe Nikki was even sharper than I thought.
"No, that's OK. She's the boss. I can wait." I thought to myself, yeah right, at this moment she's the boss, but in a minute she's going to just be my little slut.
I flipped open my laptop as I waited and sent my slut an instant message: "I think Nikki might be onto us."
About fifteen seconds later she replied, "Sorry to keep you waiting, Sir. Big trouble with DyNet. Hopefully won't be long. Nikki - No problem."
"OK," I shot back.
I opened up a demographic analysis spreadsheet I'd been developing to pass the time. After a minute or so another message popped in from Adrienne, "Nikki knows everything. I told her this morning. It's all fine. I'll explain later."
A sudden panic shot through me as I pondered the implications that our secret was out. I was shocked, but also a little exhilarated that Nikki knew of our exploits. Everything? Really? Did she know that I was Adrienne's Master and she my sex slave? Did she know about all the exploits we'd shared in Adrienne's office, in the parking garage, in the third floor men's room? I caught Nikki looking at me several times, and wondered whether she was intrigued, offended or turned on by whatever she knew.
Just as I began entertaining a fleeting fantasy about having Nikki as my sex slave too, Adrienne's door opened and she stepped out looking extremely sexy in a short, tight black skirt and sleeveless blouse, both of which I had my hands inside of within seconds entering her office. We shared some intensely passionate kisses, with lots of frantic groping, before my curiosity about Nikki got the best of me.
"How'd she find out?" I asked, a little breathlessly.
"Can't I explain after I suck your cock, Sir?" Adrienne asked, as she eased down my zipper and slid her hand into my pants, squeezing my growing manhood. "I need your come, please!" She was practically begging.
"Sorry, my little slut, you'll just have to wait to have my come until I say it's time. Now, tell me about how Nikki discovered us."
Clearly disappointed and practically pouting, she released my cock and moved around behind her desk.
"Well, truthfully, she didn't discover us. I told her," she explained plainly.
"You what?" I was incredulous.
"Nikki has always known about my lovers, and she's been an essential ally in keeping my tracks covered, especially with my husband. She's set up meetings with them, made hotel reservations, bought gifts, made phone calls. She's really amazing."
"And she's never resented it or felt used?"
"Nikki and I have an understanding. Let's just say she is very well compensated for her services. We both appreciate the importance of what she does for me. She's never done anything to betray my trust or my confidence."
"But don't you think exposing an inter-office tryst is a lot riskier?" I asked bluntly.
"Frankly, Jason, if we're going to keep this up, we need her. And it was only a matter of time before she figured it out anyway. She's very sharp."
"I suppose you're right," I finally admitted.
"I'll prove it to you. Unlock the door," Adrienne said as she pressed her intercom button and summoned Nikki into her office.
Nikki entered, steno pad in hand, and I closed the door behind her.
"Jason's a little worried over what I told you about us this morning. Maybe you can help put his mind at ease."
"Yes, Mistress," Nikki answered. "As you wish."
I snapped my head around and stared at Adrienne, looking at her in disbelief and confusion over what I'd just heard. I stood speechless as Adrienne moved from behind her desk and walked over to Nikki, placed her hand on her shoulder, and guided her to her knees.
"Will you please lock the door, Sir?" Adrienne asked sweetly before turning back to the kneeling Nikki. "Do as I instructed you this morning, cunt."
"Yes, Mistress," Nikki demurred.
Slowly and deliberately Nikki unbuttoned her simple pink blouse and removed it, exposing a plain cotton bra. With her eyes fixed on the floor in front of her, she held out the blouse in front of her in her open palms.
"She wants you to take it," Adrienne told me. I walked over to Nikki and took the blouse from her hands and placed it on a nearby chair.
Next Nikki removed her bra, folded it, and held it out in the same fashion. I noticed, as I took the plain bra from her hands, that she had tiny barbells inserted into each of her pierced nipples.
"Tell him," Adrienne said sternly, slapping each of Nikki's breasts with her open hand such that they jiggled ferociously.
Nikki place her hands under her swaying breasts and spoke to me, though her eyes were still staring down at the floor. "These breasts belong to my Mistress. She chose to pierce them as a sign of her ownership of me. They are but symbols of that fact that my whole being was hers. She owned my body, as she did my mind and soul. I was her cunt and existed for her pleasure. My Mistress would like you to mark my breasts with your come, Sir, that you might claim me as yours and so you will believe in the sincerity of my obedience and my silence."
I looked at Adrienne and she nodded. "Nikki, or 'my cunt' as I call her, is yours to use as I am yours to use. She has been my sub, my slave, my cunt. Mark her and claim her as yours, Sir. I offer her to you. Take her, use her, enjoy her as you have me."
My head was swimming with a thousands thoughts and questions at once, but my body was immediately compelled to do as Adrienne had indicated. I took a step toward Nikki, and she reached up and unzipped my pants, skillfully working my cock free of my shorts. In seconds she had my manhood at complete attention, sucking me expertly, with eagerness and rapt attention.
"Don't feel the need to be delicate with the cunt. She likes it rough," Adrienne explained. "Don't you cunt?"
Nikki made half an attempt to nod and offered a meager, "uh-humph" in reply. In response I wrapped my fingers through the back of Nikki's silky black hair. I forced her face roughly onto my cock, but the hand she had wrapped around the base was limiting the depth of my penetration.
"Hands on those sweet tits, cunt," I barked out. "Pull those pretty piercings hard while I fuck your throat."
Her hands obediently went straight to cup her breasts with her thumb and index fingers pulling at the steel rods through each nipple. Immediately I started to fuck her throat harder and deeper, but Nikki never gagged or resisted in any way. Instead she eagerly opened her throat to my ardent invasion. I would have liked to toy with the cunt more, but the excitement of the unexpected scene was soon more than I could bear, and the point of no return was soon upon me.
I released her hair and ordered her to fuck me with her face and earn my come upon her. She responded by vigorously plunging her mouth up and down over my engorged manhood, no less so than when I'd been forcing my way in. I was astounded at the brutality she unleashed upon herself, including pulling harder on her nipples until they were extremely distended. In seconds my cock began to pulse, and the first jet of my hot jism spurted deeply into her throat. I quickly withdrew from her mouth and carefully aimed the subsequent flood toward her tits, which she kept stretched out before me by the nipples, as if offering me an eager receptacle. I emptied my balls all over them, moving back and forth, as huge streams of thick white goo dripped down the sides of each breast and between them.
I stepped back and observed Nikki, still kneeling obediently, still tugging on her nipples, waiting for her Mistress's next instruction, or mine, I wasn't sure.
Adrienne went to Nikki and took the spot before her where I had been standing. "My Master's come has marked and claimed you. You will obey him as you would me. You are his cunt now, and no longer mine. His pleasure, not mine, is your joy. He may have you at any time, and do with you as he wishes. He owns us both now. We are sisters in sexual slavery to him. Do you understand, cunt?"
"Yes, Mistress," Nikki replied. "I understand."
