The failsafe gets triggered

She scowled at me, staring with murderous rage. I suspected from her expression she was thinking about me dying quite horribly. What happened next confirmed it, though.

Her jaw dropped in sudden surprise and her blue eyes went wide. She shuddered violently then looked around in confusion as if she was lots.

"Candi needs to suck a dick..." she said just barely above a whisper.

"What was that you said just now Candi?" I asked.

"Candi needs to suck a dick!" she said with more confidence, a bright blush appearing on her pale cheeks.

"But I thought you didn't want to be called Candi," I pointed out. "And I never thought you were the sort of woman who gives head."

"Candi NEEDS to suck a DICK!" she explained, her lips pouting, trembling all over with the irresistible need thinking about killing me had triggered.

"Well, maybe if you said please I might let you suck mine," I conceded.

"CandiNeedsToSuckADick! CandiNeedsToSuckADick! CandiNeedsToSuckADick! CandiNeedsToSuckADick!" she exclaimed.

"Oh, that's right," I said. "I guess you can't really say please or anything else until you take care of your little obsession. Tell you what, as long as you say thank you when you're done, we'll call it good."

"CandiNeedsToSuckADick!" she agreed.

I grinned wickedly and removed my pants. Her eyes went immediately to my crotch and since I was enjoying playing with her more than a little, she gasped and shuddered in delight at what she found there. I was well on my way to fully erect.

"Candi needs to suck a dick..." she said reverently.

"Then get on your knees and suck it, Candi!" I encouraged.

She sank to her knees and walked on them over to where I sat. Her eyes and mind were filled with nothing but cock. She literally couldn't think of anything else. And it would remain so until she either swallowed cum or I gave her a safe word that only I knew. If she wanted to ask someone to kill me there was no way she would get the request out. Her chosen assassin probably wouldn't mind much if he were male though.

As she took me in her mouth I growled in satisfaction. Cynthia's ministrations that morning had been heavenly, but having Ms. Sorenson kneeling before me obsessed with sucking me off to the exclusion of all other thoughts was one hell of a turn on. Of course, she didn't even realize it was me she was sucking off. Hell, she didn't even realize it was her. She was a mindless cock sucking machine. There is something to be said for single-minded determination, though. The bitch gave great head. Even having been sucked off by her daughter earlier that morning, I could only hold on a few minutes before I exploded into her mouth.

With the taste of cum, the second phase of her programing kicked in. Her eyes went wide. She smiled around my cock. She giggled. It was an odd but not unpleasant feeling with me still in her mouth. She giggled again. She slipped my prick out of her mouth. She giggled manically.

"Candi's such a slut!" she announced proudly as her left hand found her crotch and her right hand found her right tit. "Candi's such a SLUT!"

She started masturbating vigorously, giggling like a loon and calling out "Candi's such a slut!" every few seconds. By the time her pronunciation had degenerated to "Cana susa sluth!" I knew my step mother was about to come back with a bang.

She squealed out as she was hit with a tremendous orgasm that came to her along with her original personality and thinking ability. Of course, riding a wave of that much pleasure meant she wasn't thinking much, but my programing wasn't stopping her from doing it. The twist of horror and ecstasy on her face told me I had got the balance just right.

She sprawled on the floor, gasping and shuddering, long after the orgasm should have passed.

"How about that 'thank you'" I asked.
