I'm fully aware of the fact that this part is criminally short, but I'll update sooner and with a part two times longer.

Neither noticed the quickly diminishing distance between them, until they were sat next to each other, thighs touching.

Just then Daniel appeared, harried and anxious. "Jack!"

Jack tore his attention away from the alluring woman by his side to glare at the intruder. "What!"

"I just finished translating the stela at the stargate. We have to get off this planet quickly."

That caught Jack's attention. "What? Why?"

"This planet is being visited by couples incapable of conceiving and has been for thousands of years. If exposed to the air long enough the two are eventually overcome with desire for each other and have sex. It says it doesn't even matter if they are a couple, they just have to be a man and a woman and in each other's presence for long enough. Something on the planet must also help with fertility because the success rate is apparently 100 percent. Every couple who's come here and had sex has apparently gotten pregnant. The majority of the stela is like a guestbook, with signatures of couples who've come here and gotten pregnant. We have to leave before this happens to us." he concluded his ramblings, having gotten off-track by his discovery.

Daniel stopped for air and finally noticed the proximity of the two people sitting by the warm fire. Suspicion woke up only when he noticed the liquid hot and scorching gazes they were trading. "Jack, Major..." he started warily. ".. how long have you been sitting here together?"

"About 30 minutes, why?" answered Jack non-chalantly. Rachel nodded in agreement while secretly wanting the annoying weird man to go away so she could dedicate herself fully to the Alpha, to give herself to him, be claimed by him and marked by him as his. She'd never been like this before, never been wanton, never experienced such a hunger for a man, having been shy and reserved, especially around men, all her life.

Finally both abandoned their ruses of being interested in what Daniel had to say and turned to lock gazes, finding heat and primal want there. Before they knew it they were kissing. It was not a gentle kiss, but a mating of mouths, a passionate, hungry communion of tongues and clashing of teeth.

From somewhere far away they heard a gasp and then a voice yelling at them to stop. Jack tore his mouth away from the lovely and very willing woman, his mate, in his arms and growled at Daniel. "Go away, Danny boy!" Then quickly claimed her again.

But Daniel wasn't satisfied with that and tried to separate them physically, for the thousandth time ignoring Jack's warnings. Which finally used up Jack's patience and, pulling out his Zat, he shot Daniel once. The man fell to the floor and Jack looked at his mate with primal eyes.

For that was who she was now. His mate. He was the Alpha Male and she was his Alpha Female and he was going to mate with her and no-one will be able to stop them. By the time they'd be done she would be so thoroughly marked by him there would be no doubt as to whom she belonged. Marked by his scent and physically by his mark of claim.

Quickly making a decision he took her hand, pulled her up to her feet and then made his way swiftly away from the camp into the darkness. Rachel followed him eagerly, knowing what was to come and wanting it with this man, her mate, with everything in her, even the normal, not-primal, part of her.

After 45 minutes of running they found a cave and quickly headed inside. Once there they turned to each other and fiercely tore clothes off each other's bodies.

When he was inside her, moving powerfully and feeling her respond with fervor and desire, through the haze of lust and sex Jack remembered seeing Carter and Teal'c in this same situation and finally realized what had caused them to do this.

It wasn't that they'd been having a relationship or she was cheating on Pete.

It was just the planet.

Four hours later they'd climaxed three times already and were going for the fourth one when they accidentally heard voices from outside the cave. They stilled and went quiet, waiting until the voices went away. Then they started up again.
