A/N I finally finished writing this chapter! Hurray! Sorry it took so long.

I was going to end this chapter differently, but it was getting too long, so I cut it short, and I'll continue in the next chapter.

I got the idea of the first part of this chapter from watching SG1 episode 8x06 "Avatar" with the simulation game, and after watching the movie X-men 3, also having a simulation type room for the same purposes. So I wanted to fit that in to the story somehow, hope it worked.

WARNING! The second half of this chapter is rated M+ for being very steamy and sexy; it's a little more explicit than what I wrote in the last chapter, but not too much more. I hope I don't offend anybody by what I wrote. (I've read "worse" but I'm still new at writing scenes like that, so for me it feels very HOT, and I actually enjoyed writing it, so I might write more like that in future chapters.) WARNING!

Well that's it I guess, hope you enjoy this chapter!

… they both knew what this meant to them and in their silence they agreed to try it out, it would be tough to keep it secret, and the more they would be together, the more they would have to hide, more to keep secret behind closed doors and "in the room", but they were both determined to try.

Chapter 4 - Say no more

It had been almost a month since their shower encounter and Jack was hoping that it would be easier to deal with his feelings, now that he experienced being with Sam, twice, but he couldn't have been more further from the truth. Instead of it being easier like he thought, it was all the more difficult for him, because he knew now exactly what he was missing when they weren't together (which was more often than not), he wanted her even more, and Sam was feeling the exact same thing, every time she looked at him her mind would flash back to an intimate moment between them, be it a hug, a kiss or something more, just one look and all her "suppressed" feelings would come floating to the top, they were in dangerous waters.

Keeping it secret was the real hard part, they had a few close encounters like last week for instance when SG1 were testing out the new holographic simulation room.

Flashback

Major Carter was showing General Hammond, along with SG1 and a few more team leaders who tagged along, the new Holographic Simulation Room that the SGC had developed and worked on for a while, and was now about to be tested for the first time. Everyone was listening to Carter's explanations about it; Col O'Neill was doing his best to pay attention as well.

"The Simulation roomcreates artificial environments. It's basically an enclosed room in which objects and people are simulated by a combination of replicated matter, tractor beams, and shaped force fields onto which holographic images are projected. Sounds and smells are simulated by speakers and fragranced fluid atomizers. This room was created initially for training or recreational purposes. The feel of a large environment is simulated by suspending the participants on force fields which move with their feet, keeping them from reaching the walls of the room..."

"Kind'a like a giant treadmill…" Jack offered, hoping to simplify it for himself more than for others.

"Yes Sir, Exactly like a virtual treadmill." Sam answered with a smile at his attempt to understand her words. Jack smiled smugly to himself that he actually got it right this time, as Carter continued with the details.

"Matter created in the simulation room requires the holographic emitters to remain stable and will quickly disintegrate if it is removed from the Simulation Room without a mobile emitter to sustain it…"

"Does it have any drawbacks that you know about Major?" General Hammond cut in.

"Well Sir, We haven't tested all of its attributes yet, so far it seems safe enough, although Dr. Fraiser did warn me of one negative aspect that came to her mind Sir, she said that some users may develop an addiction to the Simulation room, leading to them spending unhealthy amounts of time there. But that's something we can easily observe and monitor to make sure it doesn't happen, Sir."

"Very well Major, SG1 will be the first to test it, Col. you begin in 1 hour."

"Yes Sir" Jack replied.

One hour later

SG1 stepped through the Stargate cautiously, holding their weapons at the ready, waiting for something unexpected to happen. The planet had a very rocky terrain, large boulders were scattered around the area, Col. O'Neill signaled to his team to find cover, Daniel and Teal'c each found a big rock to conceal themselves with, Carter decided to join the Col. Behind the same rock, unconsciously wanting to be near him.

They all stood still for a while, listening for any sound they might hear; O'Neill popped his head from around the big boulder, looking around, trying to spot an enemy and before he knew what happened they were under attack from blast weapons by a troop of Jaffa.

SG1 did what they did best, fighting and staying alive. It involved a lot of rolling on the ground, advancing on the enemy, and shooting almost anything in sight. Amidst all the fighting, O'Neill suddenly stopped dead in his tracks as he looked up into the sky, he noticed 3 Goa'uld ships coming at him and his team, blowing up almost everything in their path, O'Neill looked around, Daniel and Teal'c were behind safe cover, for now, and then he noticed Carter, she was standing right in the middle of the battle field concentrating on shooting down two Jaffa who were advancing on her that she didn't notice the ships, he had to think fast.

O'Neill ran over as fast as his legs would carry him, he had to get to her before the ships did, he came from behind her, shooting at the jaffa as he ran, when he was close enough, he leapt in the air grabbing Carter from behind, they rolled together until they were safely hidden, before she knew what happened, she heard a loud explosion, the place where she stood just moments ago was a giant ball of fire and Jack had her pinned to the ground behind a giant boulder.

His body was covering hers protectively, shielding her from any danger around, they were both breathing heavily, and not only from the adrenaline. He looked into her eyes with real concern for her safety he wanted to yell at her for being so careless in the field but he was just so relieved she was ok he just wanted to hold her close to him and feel her body pressed against his, to reassure himself that she was really ok. He was overcome with emotion, and Sam sensed it as she looked into his brown eyes, they knew it was bad news. They both wanted to stay in each others arms like that for ever, but they both knew that if they didn't move soon, they were risking giving too much away, and they didn't want that to happen either, so Jack reluctantly moved off of her, got to his knees, and helped her up to the same position, they were still under fire, and so they had to stay hidden.

After that incident Jack kept a close watch on Carter, without being too obvious about it, the team finished the mission successfully after 3 long hours.

They all sat with General Hammond to discuss the virtual mission, no one seemed to notice what really went on behind that boulder, Sam and Jack were both grateful for it and hoped that it would stay that way, they gave each other a knowing look to show how they felt, and Sam smiled to herself, God how much she loved that man, but they had to be more careful.

S&JS&JS&JS&JS&JS&JS&J

A week went by since the virtual mission and no one the wiser about what happened there, Sam and Jack didn't get much time to talk about it and Sam was hoping that she gets a few moments alone with Jack off world so they could discuss it, after all, keeping their relationship a secret although being very exciting on one hand, on the other hand it was still risky and they could and up being in a lot of trouble if they got caught.

SG1 were now standing in the embarkation room geared up and ready to leave on their next mission.

"SG1 you have a go" Hammond announced.

Jack gave a little salute and they all walked up the ramp and through the Stargate.

This mission wasn't dangerous; in fact it was just a simple archeological expedition that Daniel was looking forward to be apart of. They reached their destination after a 2 hour hike, it was late afternoon and Daniel was deep in thought trying to decipher what the symbols in the temple meant, usually Sam would be looking around as well for any science related objects she could find, but not today. She was too busy trying to get Jack's attention, hoping to get him alone so they could "talk" about their situation, or more likely do other things that she really wanted to do with him, she felt like they hadn't been together for years, even though they had been together perhaps a month ago but for her it felt like years, however she was either being to subtle for him, or he was avoiding her on purpose, she wasn't sure which, nevertheless that didn't stop her from trying harder.

"Sir…" she began.

"Carter, why don't you start setting up camp? Teal'c and I will search the perimeter." Jack wanted to get out of there as soon as possible, being around her wasn't getting any easier for him, he wanted to spend some alone time with her, it had been almost a month since they were together, properly, although to him it felt like years, but he was really doing her a favor by staying away or more likely for himself, he wanted to prove to himself he could still be a good commanding officer when in the field, looking out for all his teammates, but apparently the only way he could do that was by staying away from Carter, or he would lose that battle for sure, so as Jack and Teal'c began to walk out of the temple, Sam had to think quickly.

"Sir!" she called out to him before she even knew what she was going to say. He's not getting away that easy, she thought to herself.

"Carter" he turned to face her, trying not to look nervous.

"Ermm…" think Sam, think "wouldn't it be faster if all three of us set up camp? Then we could search the area more thoroughly together…Sir" she smiled, hoping she wasn't sounding too desperate, but she had to try.

"Yes Carter, but someone has to keep an eye on Daniel while we're not here." Jack hoped she was reading between the lines of his statement, she had other plans it seemed.

"But Sir…" she was about to protest before Jack cut her off.

"Don't argue with me Carter, I told you to set up camp, that's an order!" Jack raised his voice just enough to let her know he was being serious.

Sam looked at him disappointedly, but she got the message loud and clear.

She gave a small sigh. "Yes sir."

She would have to try again later, after all they were going to be here for quite some time, a few days to say the least, she would get him eventually.

As evening closed in, Sam did the required tasks to prepare camp, while keeping an eye on Daniel at the same time. Just as she was finishing up Jack and Teal'c got back from their patrol.

"Good job Carter" Jack smiled at her, letting her know that all was ok between them.

"Thank you Sir." She smiled back at him "did you find anything?" she asked casually.

"No, the place looks pretty much deserted." Jack replied. "Teal'c why don't you go check on Daniel, see how he's getting along?" Jack said without breaking eye contact with Carter, he was losing the battle, and he knew it, seeing her after that long walk, looking so beautiful to him with the sun turning her hair into gold, triggered something in him he could no longer suppress. Teal'c raised his eyebrows at the two of them, but said nothing as he walked away to do as he was told. As soon as Teal'c entered the temple Sam and Jack wasted no time. They closed the gap between them faster than a lighting bolt, their lips crashing against each other in a passionate kiss, Jack's hands came up to hold her face, while she wrapped her arms around his neck pulling him impossibly closer. The kiss was electric; it was like they were merged into a single, blazing fountain of heat and desire that was bursting at the seams. Their lips parted, only to take a breath, at that moment their eyes locked, his dark brown eyes pierced her crystal blue's after taking a few more shallow breaths the need to feel her pressed against him was undeniable. Capturing her mouth in another sizzling kiss, he took great pleasure in the sensation of her soft curves pushing urgently against his chest as he pulled her closer to him.

They were about to take things to the next level when Jack's military training instincts kicked in, he sensed someone's approach, and very reluctantly yet swiftly moved away from Sam, she was left standing there out of breath, as if she came back from a running marathon, her heart was pounding wildly, as Teal'c walked out of the temple towards them. Jack casually walked over to his pack as if occupied with looking for something, keeping his face as neutral as possible. After a few minutes of Teal'c staring at them both, Sam got her bearings together and walked quickly past Teal'c, and disappeared into the temple.

Now that was a little too close for comfort Sam and Jack both thought at the same time.

Later that night, Teal'c was sitting by a tree, doing his Kel'no'reem and Sam was getting a fire going while Jack was in the temple having an argument with Daniel.

"Jack come on; just let me finish this…" Daniel protested.

"Daniel, it'll all be waiting for you here tomorrow, now get some sleep."

"But Jack…"

"Daniel"

"Jack"

"I'm' not gonna ask you again Daniel, move it, now" Jack was getting impatient. And Daniel felt it, so he gave up.

"Alright, alright…I'm going…" Daniel said defensively. As he got up and walked out of the temple, Jack was right behind him.

They all sat around the camp fire, eating their meals, while Daniel was rambling on about what he'd found so far, Sam was interested in what he had to say, Jack was just staring at her, he couldn't wait to get her in to their tent.

"Teal'c, you take first watch. I'm gonna get some shut eye." Jack announced. "And you two should do the same" he looked pointedly at Daniel and Sam, lingering a little longer on Sam before disappearing into the tent.

Jack got into his sleeping bag, lay down, and waited. He could hear Daniel and Sam still talking in hushed voices but he was sure Sam would be in there with him in no time, however after twenty minutes of waiting Jack was getting a little impatient, and tired. 'What's taking her so long?' He thought to himself.

After about an hour of waiting, Jack finally heard them say goodnight, and Sam walked into the tent.

"Sir" Sam whispered. "Are you awake?" Jack wanted to get back at her for making him wait so long that he childishly pretended, for now, to be asleep.

"Sir" Sam tried again, but Jack didn't move an inch. Convinced that Jack was really asleep, feeling a little disappointed, not knowing that Jack was actually staring at her body from half opened eyes. She got into her sleeping bag, next to Jack, and closed her eyes, when she felt someone grabbing her from behind.

"Gotch'ya" Jack whispered in her ear.

"Jack!" Sam gasped "I thought you were asleep" she said in a whisper.

Jack was holding her close with her back to his chest and his arm draped around her middle, his face buried in her hair. She could feel him breathing down her neck. It felt so good.

"I almost was asleep thanks to you…what took you so long?" Jack asked her still keeping his voice down.

"It's called tactics Sir" she whispered back "if I came in right after you it would have looked suspicious, besides I was actually interested in what Daniel had to say, did you know that the symbols in the temple are from…" Jack put his hand across her mouth like a gag, shutting her up, he would have used a kiss instead but she was facing the other way.

"Great thinking on your strategy plans; I'm not interested in hearing the rest…" Jack explained as he removed his hand from her mouth and moving down her back. Sam felt his hands handling her sleeping bag zipper, and heard it slowly unzipping and she bit her lower lip in anticipation for what was to come.

Once the zipper was open he snuggled up behind her, and turned her around to face him. They looked into each others eyes for a few minutes.

"God, I missed you Sam" Jack informed her before he closed the distance between them and brushed his lips against hers softly. Sam responded immediately by rapping her arms around his neck and pulling him in closer as the kiss deepened and became more urgent, in moments, her body was pressed against the soft cotton of his t-shirt, and her mouth was molded intimately to his.

"Are you sure we should be doing this?" Sam asked out of breath, still kissing him fervently.

"Why not?" Jack asked equally out of breath, his lips still pressed against hers.

"Because of Daniel and Teal'c being so close outside…" Sam trailed off as Jack pulled away from her slightly to look at her. And surprised her when he smiled at what she had just said.

"Well, I'll just have to make sure you keep your voice down then, wont I?" Jack wiggled his eyebrows suggestively, and Sam couldn't help but giggle.
"Carter what did I tell you about giggling…" and before she could answer Jack once again captured her lips with his in an even more frantic kiss than before. With that out of her mind, she instinctively tugged at his shirt, pulling it free from his pants. Catching on to her intention, he maneuvered himself just enough to lift his upper body off the floor raised his arms and swiftly removed the garment, and wasted no time in doing the same with hers. The temperature in the small tent seemed to shoot up a few thousand degrees as the soft, smooth skin of her torso met the rough, coarse texture of his. Their lips still fused together frantically, tongues meeting with a wave of desire washing over them both. As they lost themselves in their own soft moans of passion and pleasure. It felt so good to hold her in his arms after such a long involuntary break from each other, feeling her soft smooth skin under his rough hands, and he could tell she was feeling the same, as her hands traveled from the back of his neck down his back. Sam wanted to feel him all at once, her hands couldn't move fast enough, she ran her hands back up to his shoulders and around to his hair clad chest, from there she was already out of control wanting to feel him inside of her and so she moved her hands down his chest southwards, and rested on his belt, fumbling under the covers of the sleeping bag to unclasp his buckle, and just as she got to his pants zipper, his hands flew down to grab her wrists, and stopped her from going any further. Their lips parted once more as they locked eyes, Sam was looking a little confused, both still breathing heavily.

"Sorry…I gotta pee" jack panted and looked apologetic; Sam relaxed and couldn't help but giggle at his statement, relieved that it wasn't anything serious. Jack released her wrists and began to get up; Sam pulled him down on her for one last kiss, which lasted longer than just a few seconds until their lips parted.

"Hold that thought" Jack told her in a rather raspy voice, and then he got up, and left the warm confines of the tent. He stood right outside for a moment, smiling to himself, and how lucky he was when Daniel caught him off guard.

"Jack, what are you doing?"

Jack was going to ask Daniel the same question, but felt it would sound too defensive so he went for the truth instead. "Daniel, I'm gonna take a leak…" Jack hoped he sounded casual.

"Did you hear anything out of the ordinary before?" Daniel inquired.

"When?"

"Just before?"

"No."

"Mmm…I thought I heard…noises or something like that, you didn't hear anything?"

Jack was getting a little anxious at Daniel's probing questions, once again Sam had been right about what they were doing and where, yet he tried to hide his uneasiness by looking sleepy and disoriented.

"Is everything alright?"

"What? No, I didn't hear anything, you must have been dreaming…or perhaps there are wild animals wandering around." Daniel half accepting jack's answer suddenly noticed jack's bare chest.

"What happened to your shirt?"

"I was…hot"

"It's actually quite cold out tonight"

"Well…my…body temperature is higher than yours, what can I say." Jack was hoping to end this very strange and awkward conversation, and not only because he had to pee. They looked at each other quizzically, Daniel not quite sure what to make of it all.

"I'm…gonna…go now…" jack said hesitantly, and when Daniel didn't say anything, Jack walked away from camp, and Daniel, to find a tree he could hide behind.

A few minutes later Jack returned, to his relief, Daniel was nowhere to be seen, he could see Teal'c at the far edge of camp, still keeping watch over them. Jack looked at his watch, and smiled to himself at the knowledge that he still had a few hours to "sleep" before it was his turn to take over from Teal'c, and with that he strode into the tent to finish what he started. To his surprise Sam was sitting up in her sleeping bag, with her shirt back on.

"I thought I told you to hold that thought…that thought did NOT include you wearing a shirt…or anything for that matter." Jack stated, still standing, looking down at her.

"Jack, we need to talk"

"Oh, no you don't…" he said as he sat down beside her. Sam looked at him with pleading eyes, but Jack only had one thing on his mind, and nothing was going to distract him from it. He leaned in closer to her, his hands cupping her face and started kissing her soft lips, hoping he could get her back to the state she was in before he left; she tried to protest at first. "Jack…" she managed to mumble in between kisses, but he wasn't giving up that easily. He moved from her lips to her jaw, and from there he moved down to her neck, kissing her more and more urgently with every movement, she tilted her head back in pleasure giving him more access to her neck but she is just as stubborn as he is, and although it was very hard to ignore what he was doing to her, she tried to focus on what she wanted to talk about. "I heard your…conversation…with Daniel…" she managed to say in between breaths. But Jack was ignoring her he leaned in even further while supporting her back and pushing her down gently, affectively trapping her between her sleeping back and his body. His hands snaked under her shirt, Sam gasped with pleasure while Jack was caressing the smooth skin of her belly and up to her soft full breasts, still kissing her all over. He pressed his weight down on her, grinding their hips together, she could feel his arousal pressing against her lower belly, if she was going to win this battle of wills she had to do something now, or it will be too late. By now he was sucking on her nipple and moving his hands down to remove her pants when she decided to act.

"Jack…wait" She struggled to catch her breath while pushing at his chest with her hands. He stopped what he was doing, and looked down at her with frustration. "What?" he asked her with a hint of irritation in his voice, still breathing heavily. She was going to say they need to talk once more, except she had already lost her battle, her body had won and she wanted him so badly right now that nothing else mattered so instead she replied "promise me we'll talk before we go to sleep tonight." Her tone sounding desperate, Jack nodded "fine…I promise" and with that Jack grabbed her wrists which were still pressed against his chest and held them up on either side of her head and lowers his head to continue where he left off, taking a nipple in his mouth, grinning against her as she arched against him moaning with pleasure, he released his grip on her wrists and moved his hands to work on her pants, it didn't take him long to remove them from her, leaving her naked body exposed only to him, She was gasping, bracing herself for what was to come next, and Jack felt a bolt of lust go through him. With one hand he was fingering her warm and moist center, making sure she was ready for him, and with the other he was quickly undoing his belt and freeing himself from the confines of his pants, He hadn't even gotten his pants all the way off, just pushed them and his boxers down so he could get inside her. She wasn't sure how he did it, but in the next moment he had thrust into her fast and hard and they both groaned with pleasure, he stilled for a moment, afraid of ending it too soon. By now Jack knew how to please her, there was sill much for both to learn, but one thing he did know was that she liked it slow, right now it was the hardest thing for him to do, he had to fight his own basic physical urges to do that, but he was determined to draw it out as much as his body would allow, for her, so after composing himself he started to move inside her, slowly at first, and she met each thrust eagerly, enjoying every second, all the while Jack was keeping her mouth as busy and occupied as possible, to keep her moans from being overheard…
