Once in the car, Jack set out for a small spring he'd found in his Hidden Places travel book. He figured it'd take about an hour's drive and a half-hour walk to reach their destination. Plenty of time to have a little travelling fun.

"How about a little driving game?" he asked, smiling at her puzzled look. Reaching over, he pulled the bottom of her dress up, pleased that she'd followed his directions and left her panties at home. With her slit suitably bare, he pulled out one of the toys from his bag and dropped it in her lap. "I think you know what to do with this." Fortunately, they were on a straightaway, and he was able to fully enjoy watching her slip the thick, knobby vibrator deep inside her cunt, leaving only a wire that led to the control pad in his lap.

"Here's how the game is going to work. It's a test of how observant you are. I'm going to ask you questions about things we see on the drive. This control has ten positions, going from a faint buzz to a pounding fuck. For every question you get right, we'll go down a step. For every question you get wrong, we'll go up a step. Along the way, we'll have some bonus questions, like Double Jeopardy. So you can win or lose more than one step at a time. Understand the rules? Good. Here's the first question. What's the address of the cabin?"

"Ummm. 2657?" Kelli guessed.

"Ummm. Wrong. It's 3636. That puts you at level one." He watched closely as she shifted in her seat, a faint humming eminating from between her legs. "Next question. What color was the mailbox?"

He could tell she was guessing again when she answered, "Black."

"Not so good. It's red. You really need to be more observant," he cautioned, thumbing the control up to number two. As the buzzing sound increased noticeably, he wondered what number ten would sound and feel like. A jackhammer, maybe?

Two wrong, a right, and a wrong answer later, the control sat on four, and Kelli reported that instead of buzzing, the vibrator was now pulsing inside her. Unfortunately for her, the road they now traveled had few features to test her powers of observation; just trees and more trees. Although it appeared that Kelli was enjoying the stimulation so far, he knew that after a while it would become more torture than pleasure. That's when she'd be begging for relief.

After missing questions on the color of a tractor and the kind of crop growing in a field, the whole front seat was thumping from the vibrations passing through her body. Time to make things a little more interesting. "OK, here's a special question for you. Get it right, and I'll turn the control down to four. Get it wrong, and I'll leave the control where it is, but add a special punishment to your plate. You get to decide. Do you want to answer this question or not?"

He watched her squirm in her seat as she considered. The vibrator had to be getting uncomfortable, especially since it was so far inside her; her clit wouldn't be getting any direct stimulation. But he'd left the alternative open, and she didn't know how far he would go in a car on the open road.

"I'll answer the question," she said, seeming to steel herself for the consequences.

"OK. The stranger who watched us this morning was carrying something. What was it?" He immediately began humming the teapot theme to Jeopardy, indicating that she had just 30 seconds to come up with an answer.

She took every second of it before offering, "A backpack?"

"Sorry, but you are wrong," he replied in his best Alex Trebeck voice. "The stranger who watched us fuck was carrying a walking stick. And now for your prize." He reached into the bag and pulled out two nipple clamps and two lengths of chain. "Attach these to each of your nipples, nice and tight. Now attach this chain to each clamp. Clip this longer chain to the one between your tits. And now I'll attach this to the steering wheel, like so." He looked with pride on his creation. Now, every time he turned the wheel, no matter how slightly, the chain would pull on one or both of her nips. And if he had to make a big turn, like the one he knew would be coming up, she'd have to lean against the wheel to avoid having her tits pulled off. He strummed the chain, watching her wince. With the double stimulation, she was definitely on the edge of orgasm. And he aimed to keep her there.

By the time they'd reached the trail to the spring, the controller had been amped up to 7, and his clamp system had twisted her nipples so much they were swollen. Yet despite all that stimulation, she still hadn't orgasmed. Or, at least, hadn't done so with the ferocity that Jack had been expecting. After carefully parking the car in the corner of the small lot, he turned to her and said simply, "Beg for it."

Nearly sobbing, her heartbreaking pleading shocked him, the words pouring from her in a torrent that almost matched the flood of juices coming from between her legs. Her promises to do anything he asked made him smile; of course she would. He shook his head in wonder at her passionate use of so-called "dirty words" that she wouldn't have been caught dead using just a few weeks ago. Only when she put some action to the promises, throwing herself on the floor of the car and kissing his shoes, did he allow himself to be moved by her pleas. Carefully removing the clamps, he ordered her onto his lap and bent to suckle each tortured tit, cranking up the controller as he moved from one breast to the other. Her moans gathering like storm clouds, she ground her ass into his lap, massaging his dick into a devestating state of hardness. At number nine the vibrator felt as though it were buzzing, rolling and shaking, all at the same time. With Kelli now panting like a long distance runner, eyes wild and hair plastered to her back, he fumbled for the control and finally brought the control to ten. A startlingly loud clacking filled the car as the vibrator literally pistoned deeper into her cunt, simulating exactly the way he would be fucking her if he could get his pants undone.
