- Heidi -

I ride the raptor for a little while, getting more confident in it and just enjoying the sensational experience. Then I slow it down and jump easily down to walk over to my boyfriend on unsteady legs. This is turning into the best day I've had for a long time. For my whole life, even. Only one thing could make it better.

“You,” I say and tap Dar'ax's chest with my index finger, “are the best man in the universe. And you,” I tap him again for good measure, “are going to fuck me so good and hard right now.”

I unceremoniously grab his cock under his loinkilt and immediately feel it growing fast in my hand.

He grins. “Heidi like riding?”

I jerk his alien cock very slowly as it stiffens quickly, feeling the heat gather even faster in my pussy. “Yes. Like riding very much. Riding rekh, much fun. Riding Dar'ax, more fun. Now Dar'ax ride Heidi. Is funnest. Dar'ax like.”

I pull my dress off, seriously considering just getting rid of it for good since lately I seem to undress more often than a Barbie doll in a kindergarten.

Dar'ax quickly discards his loincloth, and his fully hard manhood stands skywards and slaps once against his hard abdomen when it's let out of the garment.

I see no reason to be coy, and none of us need any more warming up. I kneel in front of him and take his cock into my mouth as far as I can get it, wetting it along the exotic shaft with all its features and just sucking him off as well as I know how from the first moment.

I've never minded doing that for a guy I liked, but this is at another level. Not only does he make the most appreciative noises anyone could ask for, he also deserves this more than any guy I've met before.

My tongue slides along his length and explores the many ridges and bulbs and everything, and there's a hungry feeling in my pussy at the memory of what all that feels like inside it.

But it's not like I want him to come like this.

I slide it out and kiss the tip, enjoying the glassy and slightly disbelieving look in his eyes, as if he's not quite sure he's not dreaming this whole thing.

Well, let's see if this will convince him.

I turn around, spread my knees far apart on the soft grass and get on all fours in front of him, presenting all my charms to this outrageously hot and great alien caveman. I turn my head and see his astonished face.

“Now Dar'ax ride Heidi,” I say in a voice that's hoarse with arousal.

I know he can't have experienced this before, and he probably hasn't even known it was a thing. But I guess he lets his instincts guide him, because he calmly kneels behind me and places the tip of his cock at my dripping wet entrance. I'm so horny it's all I can to not back up and impale myself on it to get it inside me right fucking now.

But his urgency is clearly just as great, because he applies a little pressure and pushes easily into me. Half of it I'm sure is my needy pussy just sucking it in, because I've never in my life been this insanely horny. I almost come from the feeling of his outlandish cock pushing its way into me. Again my pussy has to stretch to accommodate the alien invader, but that little burn is just a part of being fucked by Dar'ax, and I already love it more than I ever thought I could. From the first thrust into my sex, my whole body knows it's him and nobody else can ever compare.

In a flash I realize that Dar'ax is the last and only man I'll ever fuck. The thought sends a new wave of heat through me, as well as relief that I won't have to kiss any frogs ever again. This man fucking owns me now. This caveman.

“Fuck meee!” I yell deliriously as he thrusts into me again, and I arch my back to present all of me to him as blatantly as I can, lowering my head to rest on my arms in full female submission. I love the feeling of being this exposed for him, sensing his acceptance and arousal in each hard thrust into my red-hot center, a center that he has claimed once and for all.

His sensational cock fills me up again and again, and once more it all melts together in a blur of hot sparks and a sizzling feeling of something big and explosive building up deep in me.

My pussy squelches wildly, shamelessly wet, and I'm moaning and groaning and whimpering and squealing with each thrust, holding back even less than last night. I never want to hold back with this man. He fills me so perfectly, like he was made especially for me. Made to precise measure.

He fucks me so calmly and deeply you'd think he never did anything else. But this must be his first time fucking a girl doggy style, so he has to be the most gifted natural talent there has ever been. Again my pelvis is all liquid heat, and again he's churning up some kind of high explosive down there that he'll set off when he's good and ready.

Stars, he's taking to this like a fish to water. He's totally in charge, playing my body like an instrument he masters perfectly. And it responds to him like crazy.

Sure, some of it is that I'm really turned on and that I really want him to be good and I take everything in the best possible way. But it's mostly him. Somehow he knows exactly what he's doing.

He has me by the hips and uses them as handles, holding me tight and pulling me onto his alien cock just the way he likes it. It makes me feel even better – he's thinking of his own pleasure, too, not just satisfying me. Gods, he's magnificent.

He increases the speed and fucks me harder and faster, and I respond with thin whimpers that turn me on completely, and I'm on the verge of orgasming even before I feel the vibrations at my clit when his second cock comes into play.

So I just go with the flow and scream out my climax and my happiness that I've found a man who can fuck me so well, in addition to all the other things he does.

And this time I guess he was on the brink himself, because he squeezes my hips hard in his hand and grunts and roars as his cock swells and shoots its juice in me in hard, hot spurts. That confirmation that I turn him on just as much as he does me takes me even higher, and I revel in the blissful feeling of the two of us just being one like this.

“I love you!” I scream out into the world, because the time for caution is behind us and now I want it out there.

I'm much less scared of the raptor now, and Dar'ax shows me how to feed it berries through the openings between its frighteningly big and sharp teeth.

“I name him Fluffy,” I state and push a berry between its teeth. “Because he not fluffy at all.”

“She,” Dar'ax says and gently tends to the hole where the control stick enters the dino's body. “It can be hard to tell, but the males usually have spikes on their heads. This one doesn't.”

Fluffy moves her teeth and I yank my fingers away from her mouth. It looks like a pretty effective meat grinder. “Ah. Fluffy the girl rekh. Did Dar'ax old tribe ride much on Bigs?”

He laughs drily. “We never rode on Bigs in the old days. Nobody else does either, as far as I know.”

“You say you first to ride on Bigs?”

He shrugs. “I had to think of a way to defeat the Nusin. I was alone, and I had nothing at all to lose. If I died, then that seemed no great loss to me. I had heard of tribesmen sitting on certain Smalls and traveling on them, and I tried that. But it never worked to my satisfaction. So I started trying with Bigs instead. First the large ones. I tried bobonts first, and if I could climb up on one that was going in the right direction, it could save me time. But I could never control them. They're too big. I tried others, too. Controlling them was always hard. Bigs don't care what happens to their outsides, because their skin is thick. But I remembered some of the cave paintings in the old village. Paintings of Bigs would often depict men riding on them and a certain point on the side of the Big was always specially marked. It made sense to me to try that. Getting inside the Big, where they're more sensitive. I tried many times, and sometimes it worked. Mostly it didn't.” He smiles and holds up his hand where there's a long, white scar.

“A Big gave you that?”

“A rekh. The first rekh I rode. The first Big I could control. And then I knew that I could use a Big to get revenge on the Nusin. On a Big I can travel faster.”

I push the last berry in between Fluffy's teeth and wipe my juice-stained hands on the grass. “And did you?”

“Sometimes. The Nusin don't have a village now. They abandoned ours when they had eaten all the stored foods. They're wandering raiders. You saw what they did to that other village. I will sometimes come across small bands of them, and I challenge them. But most of them are still wandering around the jungle. Killing and plundering.”

Fluffy stands there, breathing slowly. She's none the worse for wear, it seems to me.

I point to the little hole in her side where the control stick goes in. It looks very clean, and there's no blood or other fluids leaking out. “You think she's in pain?”

Dar'ax checks the opening again. “I worried in the beginning. Causing pain to these majestic and divine creatures seems wrong. I wouldn't want that. They're more sensitive on the inside, but I don't think there's pain. When a Big gets used to the stick, it reacts calmly to it. It doesn't actually enter their depths. There's mostly empty space where it goes in.”

I stroke my hand over Fluffy's rough side. I won't keep her for too long. As soon as I get back to the girls, I'll remove the stick and let her go wherever she wants.

Dar'ax stands with his hands on his hips and makes the sound he uses when he calls Gerk to him. I guess we'll be moving on.

We walk over to the shade and sit down beside a bush with berries that aren't quite as sour as the ones we fed to Fluffy.

I sit close to him and place my hand casually on his knee. “You still want revenge on Nusin?”

“I'm the last and only. My tribe must be avenged. I must restore my honor, so the Ancestors will smile upon me.”

He says it evenly, as if he's just explaining to me something obvious. It's going to be tough to change his mind about this. But I'll try my best.

“Mmm. I think you have much honor. Not necessary get revenge. Nusin dying. No Lifegivers. No women. Only plunder and dishonor. Dar'ax forget, join new tribe.”

He looks away to the horizon. “It's shameful to be the last and only. Only I survived the raid.”

“Yes. Only you. And you honor your shaman by not dying. You follow his wish. He give you sword, so you survive. He want you survive.”

“Survive to avenge him later.”

“Deh,” I state with conviction. “Survive to meet Heidi, join my tribe. Your shaman knew many things. Future also.”

He gives me a very yellow glance, and then he's quiet for a long time.

I let him ponder it. I have no idea why his shaman did what he did. Probably he was just a really good guy who realized that Dar'ax was young and strong and had a chance to make it. That revenge thing was useful for Dar'ax before, just to keep himself going in a deadly environment and to have a purpose. But now I don't think he needs it anymore.

Sure, I'm biased as hell here. I really want him to come with me back to the girls and join our tribe. And then I'll take him back to Earth with me. One day.

The ground shakes, and then Gerk comes out of the jungle with one half of a sophiasaurus dangling from his mouth, dripping with blood.

I get to my feet. “Disturbed him in the middle his lunch.”

Dar'ax gets his mysterious bag from the branch it's hanging from. “He eats lunch all the time. He can eat while walking.”

Fluffy recoils from the approaching dino. I'm guessing they're not natural friends.

I point to her. “We bring?”

Dar'ax helps me climb up on Gerk. “She'll follow for a while. You gave her berries.”

Ah. I'll take his word for it.

He goes and takes the ropes off Fluffy's muzzle, so that she can open her deadly gape fully. Then he turns his back to the terrible raptor and climbs up behind me.

And then we're riding the freaking T. Rex again, sitting about as high at the treetops. And sure enough, Fluffy is waddling after us. I guess those sour berries must be some kind of delicacy for her kind. Probably a rare treat, too – it's not like she can just go and pick berries with those big, clawed forelimbs she has.

The wind is in my face, Gerk is moving calmly under us and I'm in the company of the man I love. Yep, I feel really good today. So good, in fact, that ...

I half-turn and give Dar'ax a look I think he must understand, ending up at his loincloth. And yep, there's a twitch in his bulge. He must be thinking the same thing.

I flick the back of my dress up and get on my hands and knees, presenting myself to Dar'ax as lewdly as I can.

He calmly kneels down too, without making Gerk slow down. Then he grabs my hip and penetrates me in one slow, superbly confident thrust. My pussy adjusts to his alien cock again, and then the caveman is fucking me on top of his freaking T. Rex. It's such an unreal, raw and primal experience that I'm orgasming after two thrusts. If you could somehow distil sex down to its very essence, then this is it.

And now I know it for sure: I've never been happier.
