First try

I was a fairly normal person, as I saw it. I loved my family, loved my wife (but after years of marriage might not necessarily say I was still 'in love' with her), I had a job I was ok with. I had been a reasonably faithful husband (In the course of a twenty year marriage, I had twice had sex with a prostitute, but I considered that well within the bounds of normal faithfulness. It was in both cases rather unsatisfying, so I hadn't bothered after the second time). That is not to say that I was without my fantasies. I had the usual dreams of beautiful and submissive young women living only to fulfill my every desire, the occasional (suppressed) fantasies about my daughter since she turned 18, about some of my wife's friends or my female coworkers. Sometimes these dreams might be accompanied by masturbation, other times they might accompany sex with my wife (although that itself had become increasingly rare), but of course that was a far as they got.

My wife is a delightful person, but is somewhat repressed sexually. I've given up trying to get her to experiment (hence the two experiments with prostitutes, but when that wasn't the kind of mind blowing thing you see in porn, I figured there was no point in taking further risk).

But now... with money apparently not a problem (not that I was particularity poor before, but there is a big mental line between 'has enough' and 'can have infinite'), my thoughts turned to sex. Could I work this so I could have all the sex I ever wanted, without screwing up my marriage?

Actually one last thought on money, because that pile was in my way. "Instead of this, can you just make it so there would always be enough money in my pocket or on my card to pay for what I wanted?" I asked?

'Yes,' was the only reply. I noticed the money was still on the couch, and was about to ask about that, when it vanished as suddenly as it appeared. 'I am adapting to anticipate your questions and needs,' the voice added, preempting my asking.

I was thinking about asking for a gorgeous 18-year-old to play with, when suddenly there was one on the couch next to me. She had on a tube top, displaying a gorgeous flat belly and an egregious amount of cleavage, and a tight miniskirt that put her panties on full display. Her blonde hair was lose and flowing, just as I had imagined. She squirmed in the seat, then stood up and stretched languorously, running her hands over her body in a way obviously meant to entice me, emphasizing her breasts and making sure to run her hands over her mound in such a way I could make it out quite clearly through her very shear panties.

This was too crazy. I just had an idle thought and suddenly a person was there who hadn't been before. I wished she wasn't there. Just as suddenly, she wasn't.

"Power," I said quickly, deciding I should have name for addressing this thing. "Please, from now on, wait until I've thought things through and made a definite decision before you do anything, okay? I don't want everything I think of for a second coming true. All I need to have is a nightmare and suddenly there are all kinds of monsters running around."

"Of course," Power replied. His voice sounded more definite and normal, less game show and more butler now. He also sounded slightly hurt.

"I appreciate the girl," I said, trying to assuage his feelings (I wasn't sure he had them, but it can't hurt to not have the thing that can make anything happen be mad at you). "I just wasn't expecting that."

On second thought: "I want you to anticipate emergencies. Like if I were about to be in a car accident, or someone wanted to hurt me, take care of the situation before it can happen. But otherwise let me think about it."

"Of course sir," he answered, sounding a bit mollified, now with a distinct 'stereotypical butler British accent'.

I thought about the girl again. She was exactly my conception of the perfect teen. Perfect body, at least, since I hadn't given her time to speak.

"Was she real?" I asked. This brought up all kinds of moral quandaries.

'It depends on master's definition of 'real',' Power answered. 'She was physically identical to a human being, she was capable of feelings and thoughts based on your ideals, although I had not given her many beyond standing and posing as you had not yet thought how she should act, but she did not exist before I created her for you. She had no past beyond that which I could have created for her, and she ceased to exist once you asked me to remove her.'

So she didn't really exist. I wasn't sure I liked the idea. Clearly she had been created to have sex with me (certainly that had been what I was thinking of). Although some benefits were readily apparent: it bypassed any moral qualms I had about taking advantage of someone against their will, since a created person would be perfectly willing (because they were made to be so), and they could be exactly what I wanted. I decided to suspend judgment until I had tried it.

"What about real people? Actual people who exist, with their own thoughts, lives, and stuff?" I asked.

'What about them?' Power replied evenly. My implication clearly had not gotten across.

It was embarrassing, but I realized I would need to get used to being explicit. You don't want to be vague with something that could do anything. "I mean, if I want to have you bring a real woman here and have her have sex with me, can I?"

'Of course.' Power replied.
