Kelli knew it would be close. She could feel herself building toward a climax, but she didn't want to have one in front of the Park Ranger. That would be far too embarrassing. Even having it before would be bad, because one look at her would give the whole thing away. Somehow, she had to delay it. By whatever means possible. She tried thinking of other things; of movies, songs and even multiplication tables. But no matter what, the buzzing in her pussy intruded upon her thoughts. She could feel the sweat breaking out on her brow, the trail of moisture staining the back of her sweater. Finally, finally, they arrived at the guard shack. To her consternation, there was another car in line ahead of her. Who would be going to the Park on a day like this?

She pressed her legs together, then pressed her hands into her lap, as if she could will the sensations to cease. When they pulled up at the guard shack, she endeavored to keep her gaze away from the man. Surely he'd recognize what was going on. Surely he'd get a whiff of her and understand the reason for her discomfort. She gritted her teeth. She couldn't hold out much longer. Her pussy, her ass, her entire nether regions felt like they were on fire. The sensations arced like lightning to her nipples, and made her toes tingle as if they were encased in ice. She fought to keep her breathing even, though she wanted to pant like a dog in heat. As if to prolong her torture, deliberately she was sure, Jack began to discuss the merits of a seasonal versus daily pass. She could feel the Ranger's eyes upon her, taking in her anxious state. Could he tell that she was already close to the edge of a massive orgasm? Or did he just think she was excited by some sort of sexual stimulation to come? She could sense his gaze returning to her again and again, focusing on her ill-concealed cleavage and the flushed flesh beneath her thin sweater.

The effort to contain herself now consumed every iota of her being. If she softened just a bit, just a little bit, she'd embarrass herself with a screaming, yowling orgasm right in front of this stranger. She'd yank back her skirt and smash the buzzing egg hard against her stiff little clit, not caring in the least how much of her private parts this amused stranger might see.

With a jovial wave of his hand, Jack finally drove through the check-point. They passed through the partially filled parking lot, and then finally onto a winding road, which ran for several miles to the bike trail head. As soon as the tires hit the gravel of this new road, Kelli let herself go. "Oh, God. Oh God. Oh God," she panted, the buzzing, the heat, the lightning strikes all building to a blinding crescendo. She couldn't take it any longer and reached between her legs to press the egg directly against her clit, without even looking at Jack for his permission. That did the trick. The pressure exploded inside her, vented in a violent scream of anguish. Her legs contracted around the egg, adding more fuel to the fire. Her arms and legs spasmed, and her juices dribbled from between her twitching pussy lips. She desperately wanted to have something more substantial filling the void between her legs. If she could gather the strength, she would mount Jack's thick cock right there in the car. Even that thought fueled her carnal desire, sending even more waves of pleasure coursing through her. She could sense Jack's amused grin beside her, but couldn't give it more than a single thought. Her body was finally released from the insistent buzzing. She could only concentrate on the pleasure.

At the end of the path, Jack led her down one of the many hiking trails, then split off to hike cross-country. After 20 minutes of hard walking they were well and truly off the beaten path, though Kelli imagined that they might be just steps from one of the other trails. It was hard to get her bearings in the sun dappled forest. Choosing a tree at random, Jack ordered her to stand with her back next to it. Reaching into his bag of tricks, he pulled out a coil of white rope, which he used to tie her hands to the trunk, stretching her arms well above her head. He left her legs completely unbound, and Kelli didn't have to guess why.

Without pause, he reached back into his bag and pulled out a pair of scissors. She could only grimace as he bent and began cutting her skirt from the hem to the waist, again and again, until the material hung down in ragged strips. Then, after kneading her breasts through the sweater, he pulled it taut and cut out some quick holes, so that when he released the fabric it outlined her tits, leaving each breast bare and fully exposed. With a malicious grin, he stepped back and began taking pictures of her distressful situation. Bound by the rules of their game, she couldn't ask why he wanted so many pictures like this, and so her imagination began to run wild. Maybe they were just for his private collection. Maybe he was trading them with another couple without her knowledge. Maybe he was even posting them on the Internet!

She couldn't believe that she'd failed to wonder about it before. He'd taken hundreds of pictures of her over the last two weeks. And dozens of movies! What if they weren't just stored on the computer at home? What if he was posting her picture for anybody to see? What if her neighbors had seen pictures of her bending over to suck him, or were to see her tied submissively to this tree? Would Jack do that to her?

She suddenly got goose bumps thinking about a man, a faceless stranger, fantasizing about her in this position. He'd find her whimpering, tightly bound to the tree, her tits exposed, her skirt in tatters, completely defenseless and at his mercy. He'd look around for her man and find no one. Was she part of a bondage game? A kidnapping victim? A wife being punished? A play toy for a militia member? A birthday gift for a hiker who would be coming along soon? He'd inspect her from all sides, noticing the fullness of her tits, the curve of her ass, the bare slit so tantalizingly close. He could ask her why she was here, but that would mean lifting the gag from her mouth. Or he could remain ignorant of her plight and simply take what she represented. A helpless piece of ass. A chance to fuck and run.

She could picture the man in his office, her helpless form blazing from his computer screen, begging to be used and abused. She could see the man sitting there, his hand deep in his pants, stroking his cock, while he imagined what he'd do to her if he were ever lucky enough to come upon such a creature in the forest. How he'd caress her full, inviting tits, or maybe cruelly squeeze and twist them, not needing to worry about the consequences. How he'd run his hand down between her melons, down over her fluttering stomach, down to her vulnerable crevice, where he could pleasure or pain her, as his mood dictated. Would he simply unleash his cock and stab it into her right away, or would he get more pleasure in torturing her, cutting a switch from a tree to crop her ass? Would he want to bind her more tightly to the tree, or use the scissors on the ground to remove larger and larger patches of her clothing? She could see the man in his office, creating his fantasies based on her helpless, half-nude form bound to a tree, and imagine his hand speedily stroking his cock, even as he pretended that it's deeply embedded in her cunt. She could picture more men, before more computers, each beating off to a different image of her with her legs splayed and body nude, their cum drenching their pants and shorts and hands and chairs, leaving her image as cum-drenched and completely in their control. Would Jack put her on display like that? It wouldn't bother her if he did.
