I shuffled naked in the shackles my owner had me in as he moved me from my small private room back to his main dungeon where Pet was kept captive. It was degrading and very effective I knew as it set borders on my behavior and expectations. It was only the third day here for me and already I’d been conditioned not to speak out of turn or try to communicate with Pet in anyway. He’d lashed these desires out of me, and I respected him for it. Not the way I and my sisters had done it; crude almost, but as every bit effective I was now convinced. He knew the secret; never give in!
I stared at Pet as he chained my ankle to the wall and removed my shackles; my heart leaped out to her. She was sitting on the edge of the king-sized bed, bent over so far that her hair splayed out on the floor between her feet as did her arms and legs. I knew the posture and I now felt fear and apprehension as either he’d been taught such by my sisters on how to hypnotize Pet like this, or he had enough knowledge to do it himself. Either way I was fucked I feared.
We all used the techniques hypnosis provided, learned in the many psych labs we’d all taken at the university. Unethically, it could be used for domination purposes, and that’s exactly what we’d used it for on Pet. There’d been no expectation of ethical behavior on anyone’s part, including Pet’s; just a tool to reach an end. We reached that end after months, mostly by my efforts to confuse and plant false memories as our enthusiastic guinea pig let us run wild. But now I was the guinea pig.
“Sit in the chair,” Ted said calmly, referring to the simply wooden chair I’d been tied to before. “When your eyelids get heavy, let them close...”
Fuck, I told myself with a slight pout on my face, suspecting now that Ted was gloating a little, but I dare not confirm this by looking directly up at him. Even when alone in my cell, I’d mostly kept my gaze down toward the floor now. A sudden disembodied voice startled me!
“I’ll take it from here if you want,” came Sherel’s voice from the big screen TV. Ted nodded his consent and so Sherel began the simple routine to put me under. We all had routinely hypnotized each other to help prepare for exams and the like, so this was not unusual. I preferred other roommates to do this as Sherel had a mischievous dyke streak to her. “ ... don’t resist Mandy ... calm yourself ... this is inevitable, you know that...”
I knew, I told myself as I tried not to listen, but Ted’s slight pacing in front of me was a constant reminder that failure to comply would be met with harsh treatment. Maybe that treatment would be preferred, I told myself as Sherel droned on. I could fake my reactions; make a mockery of this attempt, I boasted to myself. Her voice was nothing!
I woke up; not startled but just aware enough to know I’d been hypnotized as I was slumped in the chair, and all was quiet. Pet was still bent over, deeply asleep as before and there was now a different scene being shown on the big screen, with Sherel being absent from it now. A black guy was fucking a tightly bound Pet in the scene, her being spread wide by straps running across the bed. This was my first knowledge of others being involved in Pet’s descent into male ownership. This was a BBC event I realized now, and it worried me greatly.
“Ohhh, your tight little bitch...” the black man with heavy looking balls exclaimed as he railed my Pet’s pussy relentlessly. I tried frantically to recall what I’d heard and what I’d agreed to while in a trance, knowing now I’d been commanded to forget things; all things. I’d obeyed of course, being a good semi-voluntary subject. His black cock was enormous it seemed to me as I started to sweat; bigger than even my master’s. My lesbian pussy had been greatly stretched over the years I knew, and so had Pet’s, but I suspected now hers was tightening, conforming as it were to BBC’s as well as big white cock. Mine would do the same I hoped. Was this desire a posthypnotic suggestion?
Ted stepped up in front me, blocking my view of the TV as the scene played on. “You will desire this,” he told me in no uncertain terms. Like a robot, I heard myself quickly reply, “Yes master!” It had begun, I informed myself as he reached out slowly to force my eyelids down. When I came out of a trance again the scene was over and he was noisily face-fucking Pet who was obviously still under.
“Ughhh ... whewww ... what is it that you desire,” he turned to ask me with wild eyes as he thrust in and out of Pet’s throat. There were no chocking sounds at the moment, which mystified me at first, until I concluded the deep trance Pet was in was accommodating this face-fuck.
“I want to be as good as her, master,” I replied in a pleading voice, which was true as it had to be this way. Fucking Sherel knew all the switches to throw and I’d found them all for her! True, I had to agree to them, else they wouldn’t work well, but that seemed a forgone conclusion now. My begging voice proved that to me.
“You are not on the pill—does this concern you, my bitch?” he asked as he held Pet’s head in both hands, doing long slow thrusts into her mouth now, up to the balls.
“No, master,” I blurted out, “Not if this pleases you!” The words were hollow I tried to convince myself, but my growing arousal at this fact was not. Sherel had prepped me well and I knew why. Agreeing to be like Pet meant this behavior had to be real and I appeared to already be past the point of desired return.
“It does please me ... come sit beside her,” he commanded, causing me to rush over and sit on the edge of the bed. His strong hands then closed my eyes again, but I soon awoke unwillingly with his big cock fucking my face. I tried to go under again and wasn’t sure he noticed. I prayed he didn’t as I did my best not to choke.
“Accckkkk ... accckkkk...”
The light was blinding and in a spectrum that at first confused me as I squinted against the flood lights. I was spread-eagle in a hallway of grey concrete, just wide enough to accommodate my form. They were tanning lights, I realized after a time, and every part of me was exposed, even my shaven pussy lips. Some memories began to return now, informing me that I had cooperated in this odd bondage that was clearly meant to tan my skin to the extreme. I worried a little about skin damage now.
The lights suddenly turned off at some point, causing me to attempt to look around for signs of my owner but the cord bound to my hair prevented me from turning my head very far. It was a timer that had turned off the lights, I concluded, leaving me almost in total darkness now in this seemingly damp corner of the dungeon. It was warm enough here, I told myself as I did my best to relax, thankful now that at least I hadn’t been forced to squat. That kind of training had become excruciating.
Pet could do the Asian squat continuously now for perhaps an hour without complaint or signs of pain. I could barely do ten minutes, and what’s more, balancing myself while my hands were bound high up behind my back was still impossible for me. When made to squat, I was allowed to lean my forehead against the cement wall of my chamber to keep myself from toppling over, but knew that privilege would soon be taken away. Pet looked so damn sexy when she squatted, and I prayed I did as well.
Another incidental torture was from the belt I’d been given to help loosen up my shoulders. I was trained now to buckle it to one of my wrists as I squatted, so I could pull on the belt as it hung over my shoulder, effectively forcing my bound wrist painful high up between my shoulder blades. It was prep for bondage, I knew, and I regretted not thinking of this when I’d trained Pet so long ago. I suspected now that I wasn’t going to be allowed much strength training as taught muscles could interfere with flexibility.
Again, the tanning lights came on! Obviously, I was going to be here for some time and try as I could, I just couldn’t hang my head in defeat due to the cord pulling up on my hair. I wanted his touch and attention so bad, even while not getting anything from Pet. Hanging like I was, it would be so easy for him to come up behind me and mount me proper. Not a lesbian mount! Fuck that!
Eventually, I felt his cock take its place within me; I shed tears in ecstasy.
