"Sounds like you're at the peak of the food chain down here. Up there, they're all extinct, but many other wildlife exists.", Robert said, his eyes were a bit focused on Stormfire's backside which he couldn't ignore. Not that Susan would be too upset since she was catching glimpses of Thunderwolf's impressive manhood from her angle. Both of them were human after all and seeing others like them in that state certainly made them look, but they would never act; they were truly mates for only each other.

Stormfire hummed thoughtfully, "Due to the look of your clothes, I imagine that you've moved from hunting and foraging.".

"By quite a long time.", Robert answered. "It was millenniums ago that all of humanity was like you all. Some areas took longer to adapt than others though.", he admitted; feeling some slight shame with the past on that subject. Those who didn't adapt fast enough, were either wiped out or driven to the brink; like when America moved along through the continent and the Indian tribes that were in the way.

Susan soon squeezed his hand, "But over time, we had learned how to build communities that's far bigger than the span of your mountain. We have quite the number of hundreds, thousands, and more in several places, humans learning how to live with help from advanced tools which we call technology.".

"We have some things a bit similar to that too, in some ways, we invented quite a number of things to help us.", Stormfire explained.

"I could guess, since we saw those spears of yours that looked very nice; not primitive looking in the slightest.", Robert said.

"And as for our population, it's much bigger than you can probably guess.", Thunderwolf chuckled. Susan raised an eyebrow, "I was thinking like 50 people.".

Both of the natives laughed. "Not even close, Susan.", Stormfire told her. "It may be a population fraction of yours, but it's still a large fraction.", Thunderwolf said. Robert guessed, "100 people?".

"No, it's well over a thousand.", The tribe woman informed. Robert and Susan began to chuckle. "Oh, that's tiny compared to the surface, though I guess since everyone's about six feet in height in average; I guess it makes a bit more sense with the size of the surface for humanity to be over 7 billion.", Robert told the two.

Thunderwolf gasped, "What? That's incredible!", with Stormfire nodding in agreement, speechless for once.

"Yeah, it's a bit more disorganized and all though. Nations, cities, towns, and it's fairly rough at times since a lot of people don't like each other and history on the surface has had a lot of conflicts. It's not too bad these days, especially since the discovery of alien life... and it wasn't friendly.", Susan explained as the group kept moving, Susan and Robert taking in much of the sights along the way.

Robert nodded, "But we got rid of him because we needed to save Earth, but indirectly, thanks to him, the world is actually getting better and better, and we are helping it along with our friends. It's not as gorgeous as this place, but it's improving.".

"You certainly must have tales that the little ones would love, I'm sure.", Stormfire said as they came to a stop. "Susan, Robert, our tribe.", she smiled as she motioned her hand.

Susan and Robert's jaws dropped in amazement as before them, is a town of well-crafted buildings, looking like a mix of African and Hawaiian, and there, scattered throughout is the thousand people, not counting the royals behind them.

Most of them are nude, casually walking and cooking, with some of them in coitus publicly, and the elders wearing long robes, and the hunter groups modestly wearing armor with hints of underwear.

"Susan, I think we might have found Paradise.", Robert said as the two of them walked closer, taking off their clothes as to blend in, and besides, they're strangely comfortable here. "This place is just breathtaking, you two.".

Thunderwolf chuckled warmly, "Thank you, Robert. We have certainly worked hard, and here it is.", smiling lightly as he nodded to Stormfire, and she shifted slightly, taking a deep breath and gave out a rumbling roar. One of the guards on the border patrol heard her, and blew on his horn, sounding out the arrival of their leaders.

"You two walk around and see what you think about our tribe. We'll be consulting with the elders.", Stormfire said. "Also, don't be too alarmed with a few of the pregnant ones, you two. We had our mating ceremony some time ago; doesn't happen for hundreds of years.", Thunderwolf added.

Susan nodded, "We will. And okay.", before Thunderwolf and Stormfire left the couple to talk with the elders. Robert blinked in surprise, "Mating ceremony? Sounds serious.".

The two of them started to wander around, seeing what could be seen in the village before the two of them came to a sight of two males... both of whom were heavily pregnant and shared some female characteristics as well as their masculine ones.

"Sue, are those two...", Robert slowly spoke in wonder, drawling off. Susan nodded, "I think they are.", before waving lightly, "Excuse me, we couldn't help noticing, but are you two expecting?", grabbing the attention of the two nude men.

They both nodded. "Indeed. Our mates helped impregnant us along with the energy of the Eternal Glow.", One of them said. "And from the smell of it, I think your mate is expecting too.". Both of them widened their eyes upon hearing that.

Robert exhaled in shock, "I'm..p-pregnant? With child?", and Susan asked quickly, "How could you be sure?".

"We can smell the hormones coming from him.", one of the males smiled. Both of the couple were completely shocked as Robert looked over himself before Susan noticed something off about him behind his balls.

Susan blinked in surprise, and got down for a closer look, "Robert, you're having a vagina!". Robert quickly felt himself and discovered the new organ he was growing.

"Holy shit...", Robert muttered; though he surprisingly wasn't freaking out as much as he thought he was. In fact, he started to chuckle. Before Susan could ask, he smiled at her. "Well, I guess I'm taking the load off of you this time, Sue.".

Susan got up, smiling lightly, "Looks like I have to teach you how to handle yourself while you get heavy later, and maybe massage your back as well.", before looking at the nude men, "How long ago was this mating ceremony for you? And how has it come into your tribe?".

"The ceremony was only a few months ago. We do it every couple of centuries to replace those elders we lose who have lived for quite nearly a millennium.", one of the males answered.

Robert widened his eyes in amazement, "Wait, wait, hold on, you actually live for a thousand years?". The man nodded, "More or less, yes. Oh, where are my manners? I am Mudblaze.".

"And I'm Fogdawn.", The other one nodded. "We're to guess you're the two strangers that fell from the world above?".

"In a matter of speaking, yeah," Robert rubbed the back of his neck.

Mudblaze nodded with a smile, "Pleasure to meet you.", before a voice called out, "Dad, Dad!", and the quartet looked over to see two male teenagers coming up.

Mudblaze and Fogdawn smiled warmly, "Flamepaw and Rainpaw. What's going on?". The voice from before grinned, "Guess what, I asked Rainpaw to be my mate and he said yes!".

Susan have seen several nude kids and teenagers on the way here, and now since Susan saw the vagina in Robert, she could see the same thing behind one of the teenagers' balls.

Fogdawn nodded lightly, "I am very proud of you, Rainpaw. Have you two done anything yet?". Rainpaw shyly smiled, "Thanks, Poppa. And I gave permission for Flamepaw to eat me out for the first time, and it felt really good.".

Flamepaw nodded, "And I gave permission for Rainpaw to put my little boy in his mouth for the first time, and I loved it.".

Mudblaze smiled approvingly, "Excellent, but remember, you can't mate until you are 16. As long as you succeed at your solo hunt next year, you are allowed to fight other males and females to preserve your mateship with Rainpaw.".

The two teenagers nod, and Rainpaw smiled, "Poppa, Mom is looking for you. Breakfast is ready.".

Fogdawn chuckled, "We will be along, son. Go on, you two. And tell your mother that we are expecting guests...Unless you are full of your own breakfast, new friends?".

"I think we're probably going to eat with Thunderwolf and Stormcrow.", Robert explained. "They were currently talking to the elders and said we should look around.".

"I see. Well, if you get the chance, my mate and I would love for you to eat with us sometime soon.", Mudblaze said.

Susan nodded, "We will do that, Mudblaze.", and Mudblaze smiled, "Well met, new friends.", before leaving with Fogdawn and the two teenagers nearby.

Susan exhaled in amazement, "Okay, that definitely got me a few questions to ask Thunderwolf and Stormfire. And wow, gay teenagers...You think there's lesbians here too?".

"Possibly...", Robert said. "I mean, if the males can get pregnant, then females can probably do the same. This place feels so much more progressive than back home in some ways.", Robert admitted. "But it's nothing but pure love here, you can feel it. Almost a complete utopia." He then looked down to his belly where he could just make out that his pecs were looking just a few millimeters larger. "We're going to be parents again, love.".

Susan nodded in awe, "We sure are...Wow, and to think it's only a night and a morning so far down here...You know what? I think we can stay here a bit longer, and like we promised, we could get back home on the 3rd day...This is actually a vacation adventure combo.".

"Yeah.", Robert nodded as he kissed her cheek. "And if we can't find a way out, it shouldn't be too difficult for the others to find us; Phillippe and Esme know how to get in and will probably find the hole.". He then glanced around. "You know, if they do come... we might have two more giants in the family.", he chuckled. "If Tristan comes, he might become like us, and Phillippe could finally find his love down here.".

Susan smiled warmly, "Yeah, you're right.", before humming lightly, "Let's keep walking.". And so they started to walk once more, conversations all over the place, and to their surprise, there are also some places where nude people mate in public without shame.

Like right now, on a clearing with a fountain, Susan saw three different groups of nude people at it, one a lesbian couple, another one regular of a man and woman, and the third one, a polygamous trio of two men and one woman.

"They certainly are free with their love here.", Robert smiled as he placed his arms around Susan as they kept wandering around.

"Excuse me!", Robert and Susan turned before seeing a young beautiful girl who looked about Esme and Phillippe's age and was almost as tall as Robert approach them. She had long flowing white hair and quite a number of blue tattoos on her face and shoulders while dressed in more finer looking coverings; similar to the hunting party they first encountered. "The Chief and Chiefess, my parents, want to meet with you.", she informed.

Susan nodded, "We were starting to wonder if they got done talking with the elders. Let's go, then. I'm Susan and this is Robert.".

"Pleased to meet you.", Robert smiled as he held his hand out for her. "I'm Silvergrace.", she smiled as she led the two back to the main building.

Susan and Robert came into the main building and saw Thunderwolf and Stormfire sitting on cushions around a wooden table full of dark bronze utensils, and in the middle of the table laid a well-cooked dark stone bowl of velociraptor (fast-runner) stew.

Thunderwolf smiled warmly, "Ah, thank you, Silvergrace. You are going out now?". Silvergrace nodded, "Yes, Father. The hunting patrol reported a pair of injured longnecks, and they appointed me to be the leader for today.".

Stormfire nodded, "Hunt well, daughter, and be sure not to be too reckless. Longnecks might appear slow, but their tails can whup real good.".

Silvergrace smiled, "Thank you, Mother. Well met, Susan and Robert.". The young heiress left as Robert and Susan took a seat.

"Well, we discussed with the elders, and they see no reason why not to fully accept you two.", Thunderwolf smiled. "So, if you two had any fears of us turning on you or something, rest assured.".

"That was kinda buried in the back of our minds, but that's great to know.", Robert said as Stormfire started handing them their food.

"We don't know what you tend to eat up there since you mentioned your monsters are all gone, but you two look like you eat plenty of meat.", she said.

Susan chuckled warmly, "Oh, we certainly do, along with fruit and such to stay healthy. And now with Robert confirmed as pregnant, er, expecting our child, he will have need of more food, right, my love?".

Robert nodded as he blushed. "I see you two found out then.", Thunderwolf said. "We noticed before with you two in the lagoon, but didn't say anything. We thought you two may have known.".

"No, it's different for us.", Robert said. "We don't truly know for a few months if that's the case, and, without the Quantonium exposure, males on the surface can't get pregnant at all. That's why we were so surprised.".

Stormfire gasped in surprise, "Truly?". The couple nodded in confirmation. Thunderwolf chuckled softly, "Neither way, it's a great gift to have.".

Susan spoke, "Speaking of gifts, we met a family of sorts. We met Mudblaze and Fogdawn and their kids. Apparently, Rainpaw and Flamepaw are mates of sorts, but they can't mate until 16...And Rainpaw has a vagina like Robert and Mudblaze and Fogdawn...".

Thunderwolf smiled warmly, "Ah, Rainpaw has been born with it like many other children, thanks to having a father like Fogdawn, but there are cases where other males don't have it, like Flamepaw. It's like...a top and bottom for them. If Flamepaw retains his mateship with Rainpaw after earning his warrior name after his solo hunt, Flamepaw is top while Rainpaw is bottom.".

"Very interesting customs and society you have. Ours is quite different in ways but share some similarities.", Robert said.

"It would be very interesting to hear how different your world is from ours.", Stormfire sighed. "Sorry, just thinking about Silvergrace, our daughter is yet to find a mate. She just hasn't found what she tends to feel as 'the one'."

"Sounds like our Phillippe." Robert snickered.

Thunderwolf chuckles softly, "All the same, finding the one is quite strong down here. You see, at 16, every mate feels a strong urge to make love, and if they feel right doing it, they are soulmates. But for our daughter...", sighing sadly, "She is far past 16, and she is frustrated for she has tried to feel out any male's soul and sexual attributes, and she hasn't found her soulmate. And to make it worse, she is struggling to satisfy herself.".

Stormfire nodded, "There are rare cases like our daughter, and the previous cases reported that when an unmated person finds his or her soulmate, they are urged immediately to mate, no rules or laws at all.".

"I'm sure she'll find someone soon, I know of it.", Robert assured them. "Susan and I are true soulmates, but it took us way longer than Silvergrace has before we finally embraced, right, love?".

Susan nodded with a smile, "Indeed. You see, the surface world has a rule of mates consenting to their soulmates at 18 if they want to, but the urge is not there. It's more of a ceremony to be official mates, we call them weddings. And for us, we got married at 24, and we mated almost immediately afterwards.".

"Quite a bit of a journey it was though.", Robert said. "The first time we tried to get married, we got struck by the asteroid of Quantonium and ended up growing to our current heights. We did a do-over of the wedding a short time after once things relating to our growth calmed down. And as for much of the surface world, mates aren't as strong of a thing up there. Plenty of couples end up drifting apart sadly.". Robert took a drink of water that was placed for them. "Not even an hour and already this place feels so much more like home and feels better than the surface in many ways.", he admitted.

Thunderwolf hummed thoughtfully, "The Quantonium is quite powerful down here, but up there, without finding soulmates easily, a long way of several ground crusts blocks the Quantonium from reaching up there, or am I wrong about my theory?".

Robert shook his head, "It's buried too far down into the earth. Humans up above haven't come close to reaching the core.".

Susan raised her eyebrow, "Now that I think about it, perhaps this planet used to be much smaller long ago. The continental drift and all, that might be in fact due to the planet growing in size thanks to the Quantonium. The Eternal Glow, as you call it, more than likely came from a massive asteroid as well.".

"She's right. Ours came from space, the same could be said about yours. It clearly was never originally part of this planet to begin with.", Robert added.

Stormfire smiled lightly, "That could explain quite a lot about our stories and myths.". Susan then got another thought, "We saw lesbians. Is it similar to men getting pregnant?".

Thunderwolf nodded, "Whichever female is close to the ground at the time, she gets a manhood and 'balls', and when the moment's right, that female impregnates her mate. And of course, they take turns during mating ceremonies for the pregnancies. And as for threesome families, two of them can be bottom and get pregnant at the same time. And of course, regular couples like you take turns at getting pregnant and such.".

Robert looked curious, "How long do pregnancies last down here? Mudblaze and Fogdawn looks ready to pop, and Susan, when she was pregnant with our twins, she lasted about 7 months.".

"Ours tend to be more around three or four months; it might be due to the Eternal Glow as well with how fast we have ours. That and how sexual active the tribe can be even after pregnancy.", Stormfire explained.

"On average, most humans are 9 months. That's what Susan would've been originally had we still be normal.", Robert explained.

Susan stared at Robert with awe and before Robert would ask, she spoke, "I am actually a bit jealous. And the pains? Like a sore back and feet?", looking at Stormfire then.

"It is a bit of a burden to carry them; the pains and stress is a bit of an issue, but it's not too bad and is always worth it. Of course, I wouldn't really know.", Stormfire chuckled as she grabbed her mate's hand. "Thunderwolf was the one who carried our Silvergrace.", she smiled.

Robert smiled widely, "Wow...That must have been strange yet wonderful, then.".

"Certainly was." Thunderwolf said as the two tribe leaders began to eat. "Go on, enjoy." Robert glanced at Susan as they looked at their dinosaur meal. When in Rome, the two of them thought.

Susan and Robert began to eat, and Robert hummed in surprise, "That tastes like a mix between pork and chicken. And the veggies are good too.".

Susan grinned lightly, "And the spices are delicious. It's like subtle spicy in a way. I love it.", before looking at Thunderwolf, "So, how did you exactly gave birth? I mean, I understand you're doing it woman style, but I can't imagine little Silvergrace being slapped by your manhood in the face...", sheepishly chuckling.

"Well, word of advice, Robert, you're going to have to hold onto them when the baby starts coming, they tend to come out squirming a lot and you wouldn't want your balls or penis to get struck. Our babies are surprisingly strong.", Thunderwolf advised.

Robert nodded, "That is actually reasonable.", before thinking of something else, "How about the milk? I saw that Mudblaze and Fogdawn got breasts.".

"Yes, we too can produce milk from our breasts, it's a bit of a stronger and bitter taste compared to females though, but that's really the only difference.", Thunderwolf added.

"It's certainly quite a lot to take in, that's for sure.", Robert smiled as he grabbed Susan's hand. Susan nodded, "Sure is, but we're parents once again! Oh, I am so happy.".

Stormfire smiled warmly, "It warms my heart to see a wonderful mateship like yours. And oh, just you know, in very rare cases, when someone chooses to be pregnant the dinosaur way, they lay an egg/s.".

Both of them widened their eyes hearing that. It made sense when they thought about it, but it was still quite a shock.

"Boy, being in proximity to that Quantonium all the time really does things to the body.", Robert chuckled as he took another bite of his food.

Thunderwolf nodded, "Indeed, and we're all the grateful for it.". Susan chuckled lightly, "I bet.", before the door opened up, revealing another one of the people, nude like the group.

Stormfire looked at the man, "Ah, Driftclaw. Morning report, then?". Driftclaw nodded, "Yes, by your permission. I apologize for interrupting breakfast.".

Thunderwolf spoke, "Report, then.". Driftclaw smiled widely, "Two eggs has been laid by Flashbird and Rocklight, respectively, over by Oakwood Falls. And I have a message to pass from your nephew, Bushbear. He has given birth to a beautiful girl not an hour ago. He's considering in naming her Wolfpaw in honor of you, my chief.".

"I think we should leave early and attend to family matters.", Stormfire said as she finished her meal. "Robert, Susan, feel free to enjoy yourselves in our home until we return.". The two of them finished up their meal before leaving.

"Looks like I was right about several folks about to pop.", Robert said with a grin. Susan smiled with a chuckle, "Either way, I think I could get used to being nude all the time...They aren't certainly bothered about it.".

"I'm with you on that.", Robert chuckled as he rubbed her shoulders. "Of course, that might be a bit of an issue if Phillippe and Esme somehow end up down here.", he started to laugh.

Susan shrugged, "They got used to the times we were passionate at night and all. I am positively hopeful that they would get used to the situation down here...Stormfire says that we're free to enjoy ourselves...Are you thinking what I'm thinking?".

Robert chuckled as he rubbed his hands on her shoulders before giving her a kiss. "With how often you suggest, I'm starting to worry that I'm not satisfying you.", he joked.

Susan purred, "Oh, you are satisfying me just right. This place, this paradise, I feel like I can do anything down here. And I bet you are curious about your vagina, hmm?".

"Well, I wouldn't be honest if I said I wasn't at least interested to see how it feels.", he blushed. Susan smiled reassuringly, "Then it's time for me to do all the work, my prince.", pushing him gently down on the cushion, and reached out with a hand to tease Robert's entrance.

"Oh, God!", Robert moaned as he felt his new organ being teased. "Does it always feel this good when I do it to you?", he asked as his legs were almost on the verge of crossing just to keep her from touching due to how unfamiliar his body was to the new sensation.

Susan smiled wryly, "More or less, yeah.", before she moved her hand back and forth to fondle Robert's entrance faster.

"Oh, Susan, that feels amazing...", he moaned once more as he tried to keep still for her to let her have her fun. After all, it was only fair in all the years he had done the same to her.

Susan only smiled even bigger as she felt Robert's new juices, making him wet, and she then went to put a finger into the entrance, hearing Robert gasp, "Oh!", and Susan told him warmly, "You're feeling my finger, Robbie.".

"Holy shit, that feels amazing.", Robert muttered as he tightened his grip onto the cushion. "Please don't stop, Susan... in fact, try to get more in there, like when we first touched each other?".

Susan purred softly, "As you wish, my prince.", slowly adding one, and then two more fingers, touching Robert's walls with a motion of left and right like swinging, feeling them contract again and again.

"Don't push them too deep though.", Robert reminded her. "Last thing we want is for either one of us to hurt our little one or ones." He chuckled, "We don't really have any idea with these ones like we did with Phillippe and Esme.".

Susan nodded, "Fair enough, but it's feeling really good, hmm?", now turning to pumping her fingers back and half in, with her fingers curling slightly, not wanting to scratch Robert's vagina with her nails.

"It feels great.", Robert smiled at her as she kept on going. Robert soon reached around and started giving Susan's ass-cheeks a nice soft rubbing as she kept playing with him.

Susan then moved her thumb to tease the entrance as she continued pumping and Robert gasped loudly, "Oh, gods! Now that is getting me close to the edge!".

Robert bit his lip tight as he continued to feel awashed with pleasure each moment Susan continued to finger him. He was absolutely sure she was hitting the fabled g-spot as his pleasure sensors were almost to the point of being burnt out with how much use they were getting.

Susan could feel Robert getting really tight, and she purred loudly, "You really feel so tight, love.".

"Because you're so good at this, my queen.", Robert chuckled as he let out another loud moan. "Shit, I fear we're going to be so loud; the whole tribe will hear us."

Susan smirked, "They don't care. Remember the place we saw with people doing it in public, with that fountain?", while she pumped a tad faster, figuring that Robert is extremely close to the moment.

"That's true. Still why do I feel like we'd be much louder than all of them?", Robert laughed as he felt another wave hit him. "Fuck, Sue... I think... I think I'm getting close now!".

Susan grinned, "Scream for me, Robert.", teasing and pumping faster with her fingers & thumb.

"SUSAN!", He roared out as he finally reached his limit and orgsamed all over his wife's hand. He kept going for quite a bit after that to the point it had been almost a minute before he finally stopped.

Susan smiled softly, "Five stars for your first time, huh?", licking her fingers, noticing that Robert's juices is a tad sweeter, but spicier at the same time, different than his sperm.

Robert panted as he tried to catch his breath. "That... I really envy you, Sue, you were able to experience this all your life.", he chuckled.

Susan leaned down to kiss him, "And to think you got this for a few months, better make the best of it while we can, hmm?".

"I agree... but first...", Robert quickly leapt up and switched places with her. "Sorry, love, but I don't think it still was very fair that I got to experience pretty much all the pleasure. So how about we correct that?", he smirked as his erect cock was all ready to go and push itself into her. Susan grinned, "I'm already set. Take me, Robert.".

"Still any sign of them?", Phillippe asked as he came back down the stairs of the Holmes house. When three days had passed and Butterflyosaurus came back with neither Susan or Robert in tow; their children and close friends suspected that perhaps the two just lost track of time and the kids decided to head for the Rocky Mountain complex in order to get them back home. Of course, once they got inside, they found the place silent as they looked around. Now everyone who had come; the twins, Tristan, Link, B.O.B. and Doc were very fearful that something was wrong.

Esme shook her head, "Nothing. They're not in the kitchen or library...The last place left is the basement.".

"Well, come on then... I hope they're okay.", Phillippe led the way before finally turning the last corner that led down to the deeper part of the mountain before he came to a stop along with everyone else. Obviously, what could be seen was the large gaping hole in the center of the basement. Other than that, any signs of the couple were some articles of clothing that had been strung around in the room.

"That's a hole...", B.O.B. gave a slight wow as he saw it. "There's probably our answer then, the two of them clearly were having some fun before the floor came out under them.", Link theorized as he hopped over to Robert's watch that had been placed on a bookcase.

Dr. Cockroach peered over the edge of the hole, "Goodness, quite deep from the looks of it, I can't even make out anything on the other end...".

"Hello!", B.O.B. called out and only heard an echo. "Hey, there's someone down there!".

"B.O.B., that's your voice.", Tristan sighed. "So... Mama and Papa fell down this hole... is there any way we could get down and check?", Esme asked.

Link grinned lightly, "The same way they did, by falling. And face it, Bea can't fit in here.".
