I had originally planned 'On the Beach' to be a one-shot, but since I got good reviews and requests for more, I figured 'why the hell not?', so here I go!

This one I actually got from another John/Cortana smut fic that, strangely enough, was never finished, and I haven't been able to find again. Nonetheless, I have made a couple of changes, and put my own spin on it. Hope you like it.

In the Hog

There were many reasons why Cortana felt being an actual human had an advantage over being a simple AI. One of them included the wider variety of sensations that could be felt, such as the clean, crisp air and the wind rushing through her hair as the Warthog raced across the flat terrain.

Still, as impressive as all that was, it was not quite as appealing as the man sitting in the driver seat. Glancing out of the corner of her eye, Cortana ran her blue gaze over John's impressive form. His pose as he handled the Hog was one that was both focused and yet casual. He was capable of great strength and violence, but also of tenderness and care, and more than a fair share of passion.

Cortana knew that last part all too well, given the events that had started just a week prior.

Since the end of the Covenant War, UNSC scientists had developed and perfected a technology that allowed them to transfer the consciousness of an Artificial Intelligence into the mind of a cloned human body, thus saving them from the terrors of rampancy. Cortana had undergone this process, allowing her to start a new life as a walking, talking, living, and breathing human being.

But that had not been enough to prepare her for the sudden onslaught of intense desire and sexual attraction she had felt towards the Master Chief. Not knowing how to deal with such feelings, the former AI had buried herself in other pursuits, and that particular day, had decided to go to a secluded spot in the sand dunes for a little nude sunbathing. Closing her eyes, she had sat back and let the rays wash over her naked form, while trying to push her worries out of her mind.

But then fate, coincidence, or whatever had decided to intervene. It just so happened that the Master Chief himself, John, had been running along the beach, and on the way back to the nearby base, he had unintentionally stumbled upon Cortana. The sight of her perfect nude form had been too much for the biochemically-augmented super-soldier, and he had approached her. The two had traded a few salacious words, and then made love for the first time right there on the beach.

Afterwards, the two had parted ways, but not before Cortana had promised John that she would pay him a visit later that night. That particular visit had, not surprisingly, resulted in them having sex again. Twice. In the week since then, they had made love every day, and every other moment when they were in close proximity with each other, it was a serious test of willpower for both of them to keep their hands off each other.

It definitely made for an interesting experience for both of them.

Right now, though, Cortana was just enjoying their current journey. The two of them had received orders that they were being temporarily reassigned to a nearby base in order to give them assistance in setting up shop. Since the end of the war, the UNSC had been struggling to rebuild, and thus they needed some experienced individuals to help guide the newer ones. John and Cortana had both qualified as experienced, and so they had been selected to help the new guys, whereas the other Spartans would remain at the other outpost for the time being.

Both of them, however, were simply relieved that they were not being split up, since at this point they could not get enough of each other.

"So what exactly will they be wanting you to do at this other base?" Cortana asked conversationally.

John kept his eyes focused on the road, but nonetheless kept his tone casual. "Apparently, they have gotten in a few more recruits, and most of them are a little wet behind the ears, so they need someone like me to whip them into shape."

Cortana scoffed. "You know, given the fact that our overall population is only a fraction of what it was at the start of the war, I'm surprised that more people are not focusing on rebuilding or seeking careers in professions that will help out in that area. No, we're still seeing large numbers of people joining the military. Don't they realise that the war is over now?"

John shrugged. "Even in peacetime, there still needs to be a strong military to maintain it. Besides, lots of people are still afraid that another enemy is going to attack us and they want to be prepared. To be honest, I don't really care. I'm just doing my job."

Cortana snorted derisively. John knew that she meant no offence towards him; it was just her typical stubborn attitude, and that was one of the reasons he loved her so much. Changing topics, he asked her, "So what are you doing?"

Cortana rolled her electric blue eyes. "What do you think? They tried to install a computer network, and some asinine morons totally screwed it up, so they need me to go and fix it up for them." She sighed. "These idiots think that once they get a diploma, they become undisputed experts in their chosen field and know absolutely everything!" She paused, and noticed a slight tremor in John's figure that originated from his gut; a sign that he was laughing. "Do you find this funny, John?"

John cleared his throat. "No," he replied tightly. But the sign of a repressed grin on his face indicated that he was definitely lying.

Letting out a frustrated sigh, Cortana rolled her head back. "Why do I put up with you?" she groaned.

"Because we love each other, and I know how to show that in the physical sense," John replied casually.

Pausing, Cortana looked back at the Spartan. "Very good answer," she replied with a smile, and leaned back into a relaxed position.

The base that they were meant to report into was about an hour and a half drive away from the one that the two of them had originally been stationed at, and so earlier in the day, they had loaded their equipment on to the Warthog that had been assigned to them. John had climbed into the driver seat, while Cortana hopped into the passenger one, and they had headed off.

They had been driving for almost an hour now, and the journey had taken them along a long stretch of highway that went through small plains and hills. It amazed and pleased them both to see that although Earth had been ravaged in the last few months of the war, it still managed to recover.

For the most part, Cortana had simply sat back and enjoyed the scenery. But John's casual answer had gotten her mind on to other things.

Most of the time, Cortana would wear her UNSC officer's uniform; specifically the newer version that included a zip which ran down the front. Her particular one was fitted to her curvaceous figure, and this caused more than a few of the males at the base (and even a few female ones, actually) to look at her and feel extremely jealous of John. However, given the fact that he was a Spartan, a war hero, and someone who could probably kill them with a flick of his wrist, they chose to keep their distance. Still, it did serve the purpose of getting a response from John, so Cortana was not complaining.

Nonchalantly, she reached up and slowly pulled down the front zip until it was at her belly button, then stretched her arms backwards, thrusting her ample chest out and also pulling the fabric back a little. As she had been prone to doing lately, she was not wearing a bra, so this provided an amazing view of her cleavage.

This was a blatant attempt by Cortana to get a response from John. He was occupied with driving, but he was someone who could direct part of his attention elsewhere while doing this; a skill he had developed and honed during combat, as he was often required to drive and shoot at the same time. A sideways glance and the very subtle change in his demeanour told Cortana that she had definitely succeeded in eliciting in getting a response from him.

Playing it cool, John casually and suggestively asked, "Enjoying the breeze, Cortana?"

The former AI smiled playfully. "As a matter of fact, I am." As much as she enjoyed the physical aspect of their intimacy, she would be lying if she said that she did not like the banter that they shared. If nothing else, it made it so much more fun.

Cortana placed her hand on John's knee. "I'm just being reminded that it's moments like these that I am intensely glad that they found a way to turn an AI into a human." As she said this, she slowly slid her hand along John's muscular leg. "After all, things are… much more… enjoyable this way." Her hand stopped at the end of his leg, and slipped downward into his crotch, coming to rest upon the hardness there. "Wouldn't you agree, my dear Spartan?"

Inhaling sharply, John asked, "They would not mind if we were a little bit late at the base, would they?"

"Oh, I don't know for sure, but I do know that I would not mind at all."

"I was hoping you would say that." With that, John decelerated the Warthog and pulled off the road, heading into a spot between two hills and then driving around the back of one of them. Though only small, they were more than enough to provide adequate cover. Perfect.

Pulling the Hog to a stop in a perfect handbrake spin that most stunt drivers would be jealous of, John turned off the motor and pulled his seat back as far as it would go, so as to allow Cortana some room. At the same moment, Cortana pushed herself out of her chair and climbed over to John, straddling him and assaulting his chapped lips with passionate kisses. Their movements seemed almost choreographed, and yet there was only pure emotion behind them.

Moving down from Cortana's mouth, John placed heavy kisses down her neck. He stopped for a moment as she reached down and pulled his T-shirt up and over his head, tossing it on the passenger seat. Leaning forward, he resumed his passionate assault on her neck, gradually making his way down to her tantalising cleavage.

Cortana lay back and moaned softly in ecstasy as John's mouth and tongue began their ministrations on her tender flesh. She reached down and pulled the zip of her top down the rest of the way, then pulled the garment off her shoulders and tossed it onto the passenger seat with his T-shirt. John immediately began running his hands over her firm and ample breasts, squeezing them gently and lightly pinching the nipples. After this, he leaned forward again to lick and suck on her breasts. As he did this, Cortana ran her hands over his muscular shoulders, neck and back.

After a while, John reached down to Cortana's waist. First squeezing her ass cheeks through her tight pants, he then hooked his thumbs in the band of them and started pulling them down. Manoeuvring her body, Cortana was able to pull her pants down and off her legs. It did not surprise John in the slightest that she was not wearing any panties. In fact, it seemed as though she hardly ever wore any underwear. Not that he was complaining, of course. Far from it.

After Cortana had been divested of her pants, she set about removing John's as well. Pulling them down, his erect manhood sprung into view, causing the former AI to feel a spike of excitement. Tossing both of their pants onto the passenger seat with the rest of their garments.

John leaned back and watched Cortana position her amazing body directly over his. The two of them locked eyes, and they never broke contact as she slowly eased herself downward, impaling herself on his hardness. Cortana took a moment to savour the pleasure that rippled through her, then slowly started rocking her hips.

Running his hands along her smooth legs, John reached around and gripped Cortana's ass cheeks again, urging her in deeper. Spurred on, the former AI started bouncing up and down in the Spartan's lap, her moans increasing in volume and frequency. Moving his hands upwards, John placed them on either side of the waist, supporting her body, and at the same time, he began to thrust upwards.

Cortana threw her head back and her breasts bounced with their motion. She began moaning and panting his name, further encouraging him in his thrusts. As he matched her movements, John felt himself becoming completely enraptured by the sheer sight of the beautiful woman; how amazing she was, and how perfectly their bodies responded to each other. A growing sensation of pleasure told him that he was getting close to his climax, and he fought to keep it down as long as he could. He wanted, no needed, to make this perfect for her.

Her head still thrown back in pure ecstasy, Cortana continued her movements on the Spartan's manhood. Her moans became increasingly louder, and she felt her own well of pleasure building up inside her. Bringing her head back down, she fixed her electric blue gaze on John's. His own eyes told her that he was reaching climax as well. Neither of them said anything; it was like their actions spoke for them. It was time to bring this to its end.

John and Cortana sped up their movements; him thrusting upwards, and her downwards, driving him inside her as deep as he could go, pushing each other to the brink, and reaching their climaxes almost as one.

Cortana had her orgasm less than a second before John, and the pair cried out their shared ecstasy into the empty air of the surrounding plains, knowing that nobody could hear them, but not caring if they did. She slumped against her lover, her head resting on his shoulder, feeling utterly spent by the whole ordeal. Himself also expended, John simply sat there, clutching her to him as close as he could.

Neither one of them knew how long they sat there, practically moulded together as one in the afterglow of their passion, with him still inside her. It could have only been a few minutes, or even as long as an hour. Time seemed to hold no serious meaning for them, as long as they had each other.

When John and Cortana finally arrived at the base, the commanders were understandably curious as to why they were a little bit late. The couple simply replied that they had taken an 'unexpected detour'.

Okay, this one is much shorter than the beach one, and I don't think it is as good in terms of quality, but I hope it passes. I will try to do more if I can.
