Geeker - "Oh man, Noah, I cant wait to try the ice cream you dinos have in Dinopolus!
Noah looks over his shoulder at Geeker, hesitantly regretting this decision to bring him to Dinopolus.
Noah- "Look, Geeker, this isn’t a vacation.  You need to stop talking about ice cream and focus on what I’ve told you.
Geeker perks up and quickly responds to Noah
Geeker - "I am to act like a dinosaur while in Dinopolus!  Don't do anything weird or suspicious!
Noah sighs. "This can't possibly end well...

Page 2:
Geeker bumps into Noah’s ass because he isn’t paying attention to where he is walking.  
Noah stops walking looks over his shoulder and glares at Geeker
Geeker- "Sorry Noah, I’m not used to walking with this new dinosaur body… whoa… Noah, are you a girl?"
Noah - "Watch where you’re… what...?
Geeker stares at Noah’s butt, he has a butt hole which Geeker already knows what that is.  But he has a slit right below that.  There is no cock, no balls....just a slit
Geeker- " Noah, where is your penis?   You look like a girl from down here ...

Page 3:
Noah growls a little "I’m not a girl.  Dinosaurs have everything hidden… Why are we talking about this?
Geeker groans a little as he sniffs at Noah’s  back half.  His dinosaur body is experiencing something new he has never felt before.  
Geeker lets out a moan and grinds his face against Noah’s ass, sniffing his slit and asshole
Noah turns around and stares at Geeker 
Noah- "	Geeker, seriously this is not the time for this!  If we don’t get you to Dinopolus and hide you from Molock...
Geeker cuts off Noah "Hey Noah, my penis slid out.
Geeker points down at his cock

Page 4:
Noah sighs " Geeker, we can't have you walking around with your dick hanging out. I know we dinos don't wear a lot of clothes but this is just too much. 
Geeker walks towards Noah looking a little dazed and lust filled
Geeker " Noah, can I smell you again?   I think it will help me fit in with dinos better ....
Noah  rolls his eyes "No it won't, but I can’t have you walking around like this so let me show you how all this stuff works."
Geeker vigorously nods in agreement and excitement as Noah walks over to him and leans Geeker down on his back
Noah "Okay, Geeker. This is your penis, it comes out of your slit when you are aroused.  " 

Page 5: 
Noah grabs Geeker’s cock and slides up it with his hand, pooling all the pre he has been drooling so far.   
Noah " Jesus Geeker....you are really horny"
Geeker just nods as his face blushes and he closes his eyes
Noah "This is what we dinos call a tailhole " 
Noah pokes and prods at Geeker’s tailhole.   Geeker squirms and kicks his legs around as Noah starts to finger him
Noah " Looks like the dino version of you likes anal… Heh, this aint my first time playing with another male, so you’re in luck."

Page 6:
Noah stands up over Geeker.  
Geeker opens his eyes, still trying to process all the new feelings he is experiencing.    
Noah turns around and leans over...his ass on full display for Geeker.  Noah’s cock is partly hanging out but not fully erect
Geeker looks up as Noah starts to talk 
Noah " Okay Geeker, show me what I’ve just taught you...
Geeker quickly jumps up, being only half Noah's size in this dinosaur form he finds his face level with Noah’s tailhole and slit
Geeker " This is your slit and it’s where your cock hides. 

Page 7: 
Geeker begins to fondle the bigger dinosaur.  Noah lets out a long deep purr and Nods at Geeker
Noah "Yep. Keep going.   What else did I tell you?"
Geeker sniffs the cock long and deep as it starts to fully come to life
Geeker "You smell good, Noah!  It’s making me feel so warm inside!"
Noah " Focus, Geeker!  We gotta get ya used to this so you don’t wander around with a hard on around all the other dinos!"
Geeker stops his sniffing and looks up at the tailhole 
Geeker " This is what you dinos call a tailhole. "

Page 8 :
Geeker spreads the tailhole open with his little paws and starts at the flesh.  (Dont make Noah's tailhole gaping, do something more along the lines of folds of flesh inside.   Like Geeker isnt strong enough to pull it open all the way and see a tunnel yet Ex:https://static1.e621.net/data/e9/b4/e9b42d4e69c608b1ffeb402fa26bd1c7.jpg )
Geeker cant stand just looking anymore and plunges into that tailhole face first.   
Make page 8 rimming from this point on, lots of close ups and geeker just grinding his face into that butt :P  

Page 9:
Noah Shudders and braces himself as best he can while Geeker goes to town on his ass.  
Noah " Damn, Geeker....You are a natural at this!"
Geeker doesn't bother responding, other then he starts to hump his hips through Noah's spread legs.  His little cock throbbing and getting ready to fire
Noah looks down and can see Geeker’s cock piston in and out between his legs.  
As Noah is about to ask Geeker if he is close to cumming Geeker throws his head back from Noah's tailhole and roars as cum erupts from his cock

Page 10:
this page is gonna be Geeker cum shot as Noah stands over him.   
While Geeker cums he transforms into the next dinosaur on the size chart from the refs you made.  Not sure how you wanna handle the transformation...the Show is all over the place whenever he does it so I leave that up to you to figure out :)

Page 11:  
Geeker now having just finished his orgasm and transformed into a bigger dinosaur looks up at Noah panting
Noah looks down over the bigger Geeker dinosaur
Noah " Oh shit, you changed.   Are you ok, Geeker?"
Geeker through panting says "Noah, I spurt white goo everywhere… Oh man, I’m bigger now.  "
Looking over his new dino body Geeker admires all the changes, especially how much bigger his cock has become * as well as changed shape*
Noah "Well, you may be bigger, but you’re still not as big as I am. "
Noah leans down and sits fully on Geeker’s face

Page 12:  
Geeker doesn’t get a chance to say anything else before being buried in Noahs big ass
Noah " Time for you to help get me off, Geeker. Looks like that show you put on has me all riled up."
Noah grabs his now fully erect massive cock and starts to masturbate while he rides Geekers Face
Geeker just moans and goes to town really getting deep into Noah’s ass

Page 13:
Noah is now all sweaty ( I know dinos dont sweat, but still....its hot) as he vigorusly masturbates
Noah " That's it, Geeker, you're doing great.  Keep going!"
Geekers now longer tongue is able to reach much further into Noah.  He can easily get deep enough to hit his Prostate
While all this is going on Geeker’s new bigger cock is mushed up between Noah’s legs and grinding against the lower part of Noah’s cock
Geeker is close to a second Orgasm

Page 14:
Noah is getting close when he notices Geeker is about to cum again
Noah " Come on Geeker, I’m almost there. Just a bit further..."
But before Noah can cum, Geeker starts to gyrate his hips again and begins to orgasm
Mountains of cum erupt all over noahs lower stomach and cock

Page 15:
Noah stops masturbating as geeker leans his head back and stops rimming him
Noah "Damn it, Geeker, I was so close..." he says as he slowly slides off Geeker and looks up
Geeker is now the next bigger dinosaur in the chart.  He is a little bigger then Noah at this point
Geeker "I changed again...."
Noah just marvels at Geeker and his new bigger form.
Noah " Yeah, you did. Looks like you might be big enough for something else.”

Page 16:
Noah walks around to Geeker’s haunches and looks over at Geeker’s face
Noah " Geeker, bend over and lift up your tail.   We’re gonna try some good old fashioned dino butt sex."
Geeker " Won't it hurt Noah ?  I have never done something like that before"
Noah " Don’t worry, Geeker. You’re big enough now that it should feel great for both of us"
Noah rubs Geekers now bigger haunches and starts to rim Geekers big hole

Page 17:
This page is all rimming shots of Noah rimming Geekers big dino hole.  Have fun with this page and try lots of intersting angles

Page 18: 
Geeker is in love with the feeling of noah's tongue all over his tailhole but suddenly NOah stops
Noah pulls back and admires his work, Geekers ass is drenched in spit
Noah slaps geekers flank and starts to pull it down a bit, his cock lining up with Geekers tailhole
Geeker gulps with nervesness and closes his eyes
Noah slides his dick in slowly, the big tailhole opening enough to just engulf Noahs cock

Page 19:
Noah shudders as he fully slips his cock into Geeker
Noah "Are you alright over there, Geeker...?"
Geeker just nods and says "It hurts a little, but it also feels good."
Noah "Good, ‘cause here we go."
Noah starts to thrust into Geeker
Geeker blushes hard and covers his snout with his paws as Noah goes to town on his ass

Page 20:
As Noah plows Geekers ass he starts to have trouble keeping his footing.  
Geeker is all sweaty at this point, as is Noah
Both are panting and close to orgasm, but Noah decides its time to change positions
Noah " Geeker, I want you to roll over and lie on your back for me."
Geeker opens his eyes and looks over his shoulder at noah with a nod

Page 21:
Geeker shifts his big body over on to his back, his big cock slapping against his stomach/chest
Noah walks up over Geekers tail and aligns his hips with geekers tailhole again
Noah makes eye contact with Geeker and says " So, Geeker, do you like being a dino?"
And as Geeker is about to answer, Noah slides his cock deep into Geeker again
Geeker throws his head back and clenches his teeth in pleasure

Page 22:
Noah pounds over and over at Geekers ass.  His cock pistoning back and forth
As Noah fucks Geeker he realizes that Geekers cock is hard as a rock, slapping between their two bodies
Noah leans down and starts to lick Geekers shaft
Geeker squirms again as he is overstimulated

Page 23:
Noah knows this time he is gonna cum and thrusts even faster
Geeker groans out " ...Noah...I'm..gonna cum.."
Noah " Me too, Geeker, just hold on!"
Noah grips as tight as he can to Geekers body as he cums in Geeker’s ass.  Geekers cock is trapped between them and flares open almost like a horse cock as he spews cum all over his own face

Page24:
Geeker and Noah orgasming hard and long
Noah starts to pull out of Geeker when suddenly Geeker starts to transform again
Noah flops off of geeker, his dick floping around as he falls into a puddle of both thier cum
Looking up at Geeker, he has now changed into the godzilla looking form and is much bigger then Noah
Noah " This can't possibly be good!!!"

Page 25:
Noah is laying on his back jerking off his dick, clearly drenched in sex fluids all the while Geeker is squating over Noah.  His tailhole smothering Noah
Make this page lots of close ups and different angle panels of Noah making out with Geekers enormous anus.  
Geeker is Hard as a rock but hasnt cum yet....
The comic ends here with a blurb  from Geeker saying "I’m sure I’ll shrink back down when I cum this time, Noah."
