Throughout the day I visited Ella in her cage every hour, as I had told her I would. With every visit she became a little more agitated as I entered the library, both anticipating and dreading the arousal and denial to come. On each visit she became inflamed quicker and more intensely, so that of necessity each visit became shorter: I had no intention of spoiling my pleasure by giving her an accidental orgasm. On some visits I would use my fingers to manipulate her, putting three or sometimes four fingers inside her while massaging her clit with my thumb until I felt her body begin to tremble with approaching orgasm, when I would stop immediately; on other visits I would just rub her clit while moving her buttplug in and out, in and out. Such was the level of her arousal that even such simple anal manipulation was enough to bring her to the point of coming, but again I stopped well short of allowing her to achieve climax.
By the early afternoon my own arousal was such that I brought her out of her cage, made her kneel before me as I sat in a hard-backed chair, and tit-fucked her. I would have loved to fuck her arse, but worried that it would give her too much stimulation. As it was, I took a tube of lubricant with me on that visit, a riding crop and nipple clamps joined by a chain.
I uncuffed her hands and instructed her to push her tits together; then I clamped her nipples, drizzled the valley between her tits with lubricant and pushed my cock between them.
"Jerk your tits up and down around my shaft until I come," I told her, and she instantly obeyed without question, like the well-trained slave she was, the chain of the nipples clamps jangling and clinking. After a few minutes, for extra stimulation, I removed her ballgag.
"Stick your tongue out and lick the tip of my cock." A short while later; "Now suck the head of my cock. Wrap your lips around it and use your tongue also." Now the suction from her mouth was on and around my glans, her eager tongue was flicking all around it, and her tits were still working up and down the shaft. Her nipples looked sore and swollen from the pegs they had endured earlier, and now the vicious tight clamps. Too bad. I leaned over, and casually smacked her left buttock hard with the riding crop.
"Faster," I instructed, and she did as she was told. If her arms were getting tired she didn't show it - or perhaps she knew that any failure to please would result in ten or twenty strokes of the cane, and that would hurt a lot more for a lot longer than tired arms. Also, of course, any failure in her duty would have extended her period of orgasm denial even longer: as it was she had not been allowed to come for five days, and although this was nowhere near the record - currently seven weeks - I could tell that she was growing desperate for release.
As I felt about to come, I stood from the chair. "Use your right hand to jerk me off into your mouth." Her left hand went behind her back, its default position when not being used, and her right hand slid rapidly up and down my glistening, lubricated shaft. She opened her mouth and put out her tongue, and I erupted in long streams of ejaculate into her mouth, over her tongue and chin, breathing hard. Without needing to be told she swallowed it all down like the good slave she was.
"All of it," I said, and she scooped up with her fingers what had splashed onto her chin, sucked her fingers, and swallowed that too.
"Suck me clean," I instructed again, as I had that morning, and she obeyed, taking my softening cock into her mouth and gently sucking it until there was no race of semen left.
I replaced the ballgag once more: "Now back in your cage."
An hour later I was back again, probing with my fingers, stroking with my thumb...
