You've been fairly certain your partner can carry the eggs, so after a final scavenging of the area for some kind of hide to keep you warm, she seems to agree its best to get moving now. Whatever hide she found is ragged from her having to rip it off with her teeth, and is draped awkwardly across her; you're not sure if its supposed to be a skirt or what, since you're still exposed to the elements yourself... Its also not been tanned properly, since your partner hasn't found anything to boil it... But it will do.
You think the girl inside the dick is laughing at you, as you can hear her mental voice coming from her. She hasn't really said much since you met, but you haven't exactly had much to say either... but you're fairly certain she can hear you.
"So... How did you end up in this situation?" you try to ask, trying to send your thoughts to her, "I kind of got here because of some kind of arcade cabinet… I kind of entered in the dino pussy thing as a joke."
There's a moment of silence on her end before she responds. "There was... Kind of an app game... I though it would spit out some kind of romantic novel, so I put in what I thought would be kinkiest."
You end up laughing at this, causing contractions through your body making you leak a bit with arousal.
"So... Is this anything like you imagined?" you ask.
You see them twitch their tip out of the sheathe a little and back, and you get this sense from you that she wants you to think its a shrug. "Well, our meeting was cool... But... Its the time we're not mating that things get kind of boring... And for all I know, we might be stuck like this until we die... Maybe longer, assuming 'permanent' means forever."
You see the legs of the partner your attached to moving around, as if she's gathering a few things. She's left a hunk of half eaten meat on a frond of some kind, and given you've started to get the sense of how she's positioned, you think she's scooping up the eggs into her mouth. You've heard once that crocodiles and alligators sometimes do this as well.
After a bit, you're facing the frond again, and you see she's tied up the frond a bit. You get this sense from her she wants you to figure out how she's going to carry it.
"Um... you think your partner can help us carry the meat?" you ask the girl dick
The male rex soon moves over and picks up the makeshift bag of meat, and slips it under the hide your partner threw over herself. After he moves back a little to tie up the hide under her tail. Your partner then gets the idea and ties up the front end. After she tests it at bit, you can feel her making you flushed, though it seems to be more in thanks to the other rex than for you.
"Thanks" you offer to the girl dick. And you soon hear your partner trying to imitate the sound of the word, probably to thank the male rex, coming out as something like a couple of high pitched croaks. Not exactly a sound you expect to come out of a 15 foot tall monster.
"We headed somewhere?" the girl dick says.
"South mostly, in the short term until we get somewhere warmer, since I think it might be years before the Ice Age is completely here... In the long term... I'm not sure, that probably depends what continent we're on, but whatever's closest to the equator," you say.
"If this world is anything like pre-historic Earth... We're on a continent that's basically western America... We could probably reach Mexico," she says. Its a moment later that her partner picks out a log from the fire that was keeping your cave warm, and holds it in his mouth like a torch. "I think my guy should take point, I see forward, and I'm guessing you give your girl some eyes in her backside, so you'll know if we're being snuck up on."
"Lead the way," you offer.

After a few days of travel, things settle into somewhat of a routine for your partners. Early morning travel as the sun rises, some lunch and then scavenging, mostly finding already dead dinosaurs that your partner seems pretty content with eating (which the girl inside the male rex's dick assures you is normal, t-rexes probably were scavengers, kind of like giant vultures)… And in the afternoon you searched for shelter. Every so often you'd notice them stop to move the fire into another log, probably since its easier than restarting the fire from scratch.
They take to sleeping together to share warmth, which you're not sure if it would be as effective as it would be with humans; given that on one hand if they're cold blooded they won't produce much heat of their own, but given that they're so big they should make some heat, and it might be more making sure whatever heat they loose stays between each other.
Then again, as they sleep together like that, they do line you and dick girl up so she can plug herself inside you. You're not completely horny as you were after you last laid eggs, but getting to be in close contact with one who knows what you're going through is nice.
As weird as it is to sleep when you don't have eyes to close, you do wind up having some odd dreams, perhaps sparked by the sleeping sexual fantasies of your own partner... One that you can't seem to get out of your head is one where your human body is resting on top of the lower half of a female t-rex, and you see what can only imagine is the upper half of dick girl's original form, a pair of bouncy looking breasts on an otherwise petite frame; all perched upon the lower half of her partner, thick dick bouncing and erect with every movement.
She holds you down as she spears you with it, and after a moment of savouring the fact you can feel your legs kicking as she teases you, and your back arching, you see the t rex you're attached to standing above you wearing a maid outfit with some crotch less panties and a grater belt holding up a pair of stockings... She lowers herself down on you, and you feel yourself fusing once more with her vagina; your ass fussing with hers, as do your legs, and you're left with the most you can do being to shake your ass at the dick girl and dance around. She doesn't waste time after her dick has slipped out of you before you're seeing her kiss your vaginal lips, and soon, before your eyes, you see her head starting to turn once more into the shape of a dick, and soon, the feeling begins to drain from your legs, and she slips inside you.
… Its shortly after this that you wake up filled with the lingering sensation of orgasm, sopping wet, and feeling like the dick girl inside you has had a similar dream.
It leads to some interesting conversations at least.

About a month after you departed together, you can hear the male t-rex ahead stopping, as if taking a look around.
"I think there's a rain forest ahead, the humidity is going to be a bit annoying, but it should be fairly warm for some time," dick girl says.
Your partner by this point has been eating a lot lately as the food has gotten less scarce, and you find she's gathered a lot of pelts over your trip, it now feels a bit shy of a sauna under her tail. You can feel bloated, all the way in the back of yourself, as a new clutch of eggs is almost ready. You can still only control the vagina you're inside, an the rest of her reproductive tract you guess, but you have been starting to feel sensation from across her belly and her ass and thighs lately. You wonder if you'll eventually get to feel all her senses, even if she's still the one in control... But as you feel another contraction strikes you deep in the back of your 'throat', you can't really stop to think that far.
"Just find us somewhere to lay these eggs, I'm amazed the last clutch could wait through the journey without hatching, but I can't exactly hold the eggs inside me in much longer," you say.
"Wait, I think I can see... There are other dinosaurs crossing this cliff up to this area... I think they're carrying a lot of stuff like we are... I don't think there's other t-rex with them though" she says.
You think about this for a moment. "If our partners can restrain themselves around them, then maybe later we can follow at a safe distance. Best case, they're helpful, worst case... We can scavenge off them if something else kills them. But for now... I guess we should make a nest a fair bit further... We don't want them to try and steal our eggs."
The dick girl giggles. "You've gotten quite fond of these eggs haven't you?"
You feel yourself get flushed with arousal; but you urge your partner to continue on... You've got a family to take care of.
