That first night set the tone for the proceeding weeks, which were like a roller-coaster ride on a fast track through Sex World. Natasha's carnal athleticism continued to astound me, allowing us to fuck in positions that I never could have dreamed up. Her sexual appetites, having been switched on, seemed to be just as boundless as the rest of her physical energy, and my stunned dick had no problem getting hard again and again for a woman so beautiful and sexy. And unpredictable, especially for someone being controlled. Teasing me while I was on the phone with my mother that first night was merely her opening salvo. As she had admitted before, misbehaving made Natasha hot, and now her heat was blasting my way, often at the strangest times.

I got a sense of this the evening after we first fucked. I was all abuzz emotionally, trying to decide how aggressively I wanted to experiment with the crystal, because I had it in my possession now. There were times when I held it in my palm, sensing its ruby red power emanating into my flesh. Other times I was struck at how it looked like a hunk of costume jewelry as designed by Salvador Dali, its mismatched angles not quite adding up somehow. I really didn’t know what it was, but I needed to learn what it could do. Could I control only Natasha, or others, too?

At work that that day, my boss was a total jerk, creating unnecessary problems that slowed things down and kept us working until seven. I had the crystal in my pocket, and the thought surfaced that I might not have to put up with his shit — or anyone else’s shit — ever again.

I said something about my moral compass as I began to write these recollections, and this would have been a good time to take a good long look at the needle. Perhaps I would have seen it pointing south, or even down towards hell. Maybe I would have taken stock of my situation, and asked a whole string of questions that were never considered. The first: Why me? How did I come to possess the crystal after Natasha had kept the thing for years, apparently as a keepsake? And why had the magician parted with the gem in the first place? Had he died, or been killed? And how had Natasha ever been allowed to become involved with Lester Hart? Wouldn’t Anton have used the crystal’s power to keep her as his love slave, much as I was planning to do?

I should have put more thought into how far I really wanted to take things, assuming that the crystal’s powers were extensive. I’d heard the absolute power proverb, but at eighteen, did I have a real understanding of the concept of a slippery slope?

I definitely had a new awareness of Natasha’s slippery slit the evening after we first fucked, and I was probably thinking about it while driving to the mall after work to buy some jeans. I intended to head over to Natasha’s house from there, because Josh was still away, giving us the opportunity to go wild on each other again. I was dying to see what she would be like after a day of pining for my cock. Would she want to fuck me the instant I walked through her door, or would there be some semblance of relationship, with the fucking happening later?

I thought about these things while trying on jeans in a department store changing room. I slipped my old pants off to try on a new pair, and jumped when I saw the little door swinging open. There, her eyes lit with sexual fire, stood Natasha.

"Wha...?"

"Off with the jockeys, lover," she demanded, pushing me back into the cramped space.

"How the hell…"

"I've been following you for the past twenty minutes," she whispered. "Why did you work so late? I needed to fuck you! Now get naked for me and try not to make too much noise."

We both stripped down to nothing and fucked ourselves silly. Natasha used the narrow walls to advantage by bracing her legs against them, essentially doing a full split in mid-air, thereby holding her gleaming pussy at cock-level for my benefit. The strength necessary for her to maintain this position was mind-boggling, especially when I thrust into her at full speed. I remember leaning back, just to witness the rock-hard muscles of her thighs and calves bulging and tightening as I fucked her.

Just as we were nearing blast-off, a store clerk came into the area and asked whether I was having any trouble. We eased up to quiet our sloppy friction, and I called out that I was having trouble slipping out of a tight pair of jeans. I heard the clerk chuckle and leave. Maybe they knew what was going on or maybe not, but we surely would have been caught if Natasha's legs had been visible down below the three-quarter length door. The moment we were alone again, we cranked things into high gear and I filled her pussy with my spunk, unable to suppress a loud groan at the end.

Panting and still somewhat in shock at what we had done, I collapsed onto the little stall bench, and watched as Natasha gave me a show in the way she put her skirt and blouse back on. She left her panties off, and held them out to me.

“A souvenir,” she said. “I’ve been dripping into them all day, waiting for you to be free. I want you to have something with my scent on it for the times we can’t be together.”

And then she was gone. I sat there, deliriously happy, yet wondering: What had I created the night before? When I told her to have sex with me in ways that made her hot…

I got something to eat and then drove to her house. It was mostly dark by then, the sky above a clear greenish blue. Natasha’s car was there, but no lights lit her windows, which seemed strange. I quietly strolled around the side to her back yard, getting out my key as fireflies hovered and blinked all around.

I thought I heard someone call my name in a soft voice. I looked around and saw no one, but a few seconds later I heard it again.

"Back here, in the tree house," the voice said.

There was still enough light to see the way, and when I reached the bottom of the ladder, I called up in a whisper.

"Natasha?"

"Come up here, you fool."

I did.

I've learned since that you can ask any great chef what distinguishes a superb and memorable meal from something more ordinary, and they’ll all tell you two things: fresh ingredients and fine presentation. With Natasha Hart, the fresh ingredients were a given. I don't know what I expected to see when I went up the ladder, but it turned out that the woman certainly knew all about fine presentation, too. The two narrow mats I'd seen in the structure before had been replaced by a broad foam mattress of luxurious depth, the little fluorescent camping lantern supplanted by a series of votive candles. And Natasha herself — she had to know how devastating the effect was, with her svelte, astoundingly toned and voluptuous body tightly sheathed inside of a translucent body-stocking, every hard muscle and stunning curve perfectly accentuated in the low, flickering light.

She was lying there on her side, her head resting in the crook of a folded arm, and the look she gave me as I gazed into this den of seduction was almost enough in itself to make me blow my load. Her legs were drawn up into a slight curl, until she straightened them and lifted the upper one up high to the ceiling. I saw what she wanted me to see — the wide oval opening at the crotch of her garment, and her bare pussy, glistening in the candlelight.

"I knew you'd come," she purred. "I’d never have left that changing stall if I hadn’t known I’d get to fuck you again tonight.”

A lump formed in my throat while an even bigger one pushed at the front of my pants. The tightness of the body-stocking compressed her huge breasts together, creating the most astounding line of cleavage I'd ever seen. I felt a wave of desire flood my system, causing my legs to shake. I started to climb through the small door but she told me to stop.

"You can't just barge into a woman's private lair," she admonished me. "You have to offer something to gain my favor."

I was trying to think of a response when she took matters into her own hands.

"I know just what I want," she said.

Poised with my legs and feet inside the tree house and the rest of me from the waist up still out in the cool night air, she lowered my zipper and pulled my dick out.

"You wouldn't even believe how many times I've thought of seeing this again," she told me. "You have the most beautiful cock I've ever seen, Brian. I’ll never be able to get enough of it.”

She took me inside of her mouth then, and I could tell from the first swallow that this was going to be a seriously intense ride. There was a profound knowing in this mouth, a connection so right that it was as though my dick and Natasha's lips and tongue were transmitting instantaneous messages back and forth in the warm sea of her saliva. I held onto the log siding outside and felt her mouth wrap around about half of my length, and then she did... something...

Everything went all swishy as her mouth flooded with more saliva, and then her cheeks compressed the sides of my dick in a special way. Her cheeks? Why hadn't anybody else thought to use their cheeks like this on my rod? I moaned, way too loudly it seemed, even though no one else was out there. Natasha disengaged her mouth and then her head appeared at my belly, looking up.

"You liked that, didn't you?" Enthusiasm, pure enthusiasm on her face.

"Uh-huh."

"How about this?"

Her head dropped down and I felt her lips wrap around just the head of my dick. I almost let go, which might have been disastrous, when her mouth — her whole head, actually — cork-screwed around and around, back and forth in each direction. I was literally being mouth-screwed! Again I groaned, and I felt my cock twitch in her mouth. I was only seconds from exploding.

She suddenly let go and looked up at me again. "You really responded to that! I'm beginning to think that I should grant you full admission to my little abode, so that you don't end up crashing to the ground."

I was pulled in by my dick.

"Off with the pants and lie on your back," she directed. It occurred to me that I was getting the best of multiple fantasies in this situation. Natasha was firm and almost domineering, but only because her jets burned so hotly from my commands. Maybe what turns me on is completely fucked-up, but I was doubly-hard from the duplicitous levels of control and deception.

Once I was naked, she lay on top of me, the fine texture of her sheer garment causing her incredible body to slide over my skin with slippery dry friction. She teased my chest and stomach with her big tits before bringing her lips back to my towering cock.

"I want us to explore the things that really turn us on, Brian. I want us to learn together. But I need to know right now that you'll stick with it, that you'll keep coming back to me no matter what."

She licked the underside of my shaft, one long, luscious run of her tongue, before continuing. "Will you keep coming back?" Her lips opened wide and she took about a third of me into her mouth. Again I felt her cheeks collapse around me, and when she twisted her head it felt divine. She released me with a loud "thwop", then asked again, "Will you keep coming back?"

"Y...yes!" I answered.

"Are you sure?"

Back inside her lips I went, and she did this inch-worm kind of thing, closing and loosening the pressure of her mouth as she took me in bit by bit. It was simple but incredible, and when I was about half-engulfed, I cried out, "Ohhh, fuck!" because the sensations were becoming so intense. I felt like someone had hooked my dick up to an electric generator. A tingling went all over my body, making my fingers buzz with energy.

She released me quickly, a wicked twinkle in her eye. "Are you absolutely sure? Or do I have to convince you to come back?"

"I…"

"Tell me how much you want to fuck me."

"I'm dying to fuck you, Natasha."

"Tell me that you'll fuck me every time I need you. Promise me that you'll fuck me as hard as you can for as long as you can, no matter where we are. Promise me that."

"I promise."

"It might not be easy on you. You'll have be patient at times, especially when Josh is here. You'll have to let me find ways to make it possible. Can you do that? Can you let me find ways to fuck you whenever it’s possible?"

"No problem!"

"All right, then. I have something in mind that I haven't done in a long time. Let me see if I can remember how..."

As her mouth wrapped around my tool again, I had one question flood through my mind: How could that magician or even Lester Hart have let this woman slip out of their clutches? Somehow the magician had lost Natasha despite possessing the crystal, and her ex-husband had alienated his wife and run into the arms of some other girl! Were they insane?

If your life has been anything like mine, then perhaps you've seen how quickly rational thoughts can be swept away by a mouth so talented at oral sex that it should be marked with some kind of warning sign. Natasha swallowed a third of my big cock and swirled saliva all around it, then began to bob her head up and down. Her tongue danced against me inside, and I figured that giving hummers was all coming back to her quite nicely.

But she hadn't even gotten started. The first second or two that I felt my entire cock drawn down her throat, I couldn't believe that it was actually happening. I knew about deep-throating, but had thought it more of a sexual urban legend, or something that only professional porn stars could do. I was so shocked that I made some kind of wailing sound that must have sounded like an animal humping its mate out in the trees. Her head went up and down on me like no head had before, and I could feel the tip of my cock slipping along the back of her throat at the same time that my balls bumped into her chin on the full intake. She opened wide and swallowed them, too, and I just lost it completely, spewing in a sudden, almost violent explosion. I probably screamed, but I'm not sure, because it was like all of my other senses were momentarily wiped out of existence. There was nothing but her mouth and my spasming dick and the jolting electric pleasure, and I have to admit that in that moment it felt like nothing else was really very important in life.
