Two youngish goats walked into the reception area for a movie theater, the older one taking his pre-teen brother out for "Red Rockets in Space" , both were dressed in rather plain clothes with jeans. "I want the biggest soda bro!" the smaller one pouted , the old goat scowling slightly but going ahead and buying his precious bro the largest one. "Your going to be pissing the whole movie ya know?" he ruffled the younger boy's hair as they went and sat down near the middle row. The room was surprisingly fairly empty, not that odd for an early morning, the older bro had skipped out on school to take his little bro out to see his movie. 

They sat down, watching semi-regularly as they waited for all the shill ads to play out before the proper movie out, Ziek the younger goat was already sucking down his soda and cramming popcorn into his mouth, with the older goat Aaron smoking a blunt and checking his phone. The older goat grinned occasionally as he browsed his phone, reflecting on the pictures of his bro he had taken before with the younger goat in various compromising situations. A few of the photos even had Ziek as a cute little naked toddler, the poor goat being cursed to regress in age when he got embarrassed, it was a struggle to keep him above teenage years with how often the goat popped boners in front of others. 
Finally the movie had started, Ziek's eyes were glued to the screen, his popcorn already halfway done and his drink starting to get low. Ziek was already shifting occasionally in his seat, an obvious sign that before long the goat would need to go pee. Aaron was almost nodding off, occasionally rubbing the bulge in his jeans as he scrolled through his pictures. Before long Ziek was whining, holding the front of his pants, Aaron meanwhile had unzipped his jeans and was fishing his steadily stiffening cock out of his pants and eventually turned to his little brother "Heey Ziek, need ya to take care of this'' he smiled and Ziek shuffled in his seat "Big brooo I gotta potty....." he stammered out. Aaron for his part frowned "Don't you want to repay me for taking ya out to this movie? I know you have been wanting to see it all month" he murmur'd under his breath but still hearable for Ziek ``Guess next time we won't skip school".
Ziek shook his head quickly, desperate to piss but also not wanting to make his big bro mad "O-okay bro...just promise you'll cum quick!" he softly bleated, with the older brother just smiling and nodding. Ziek took a paw off his crotch and started rubbing his older bro's huge cock, his paw trying it's best to get his older bro off before the inevitable happened. 

"Better use both yer paws or your gonna be here all day" the older goat moved the younger's paws from his pants and placed them both on the older boy's cock. Ziek whimpered and held his legs tight, crisscrossing the best he could even as he focused on making his bro cum. His paws deftly worked the shaft, quickly getting it slick as Ziek measured how much he could focus on Aaron's cock without pissing his pants. Sadly this was in in vain as slowly but surely Ziek's tinier sheath spurted a couple shots of piddle into his briefs, only a little at first but soon the metaphorical dam in his pants begun leaking and soon burst. "N-noooooo!!" Ziek whimpered as his pants flooded with warm piss, quickly soaking right through his tighty whity briefs and through the jeans on his bottom and into the seat below and pooling down onto the floor. Ziek for his part couldn’t hide his emotions and started to cry as he desperately put his paws back on his pants, trying to plug the dam back up, but there was no stopping it now. The older goat laughed slightly and rubbed his erection as he watched his little brother "Should've listened to me ya little runt" . The goat shifted as he realized his pants were getting looser even as he tinkled in them, and his shirt got smaller as held up his soaked paws to look at them, they were shrinking too and Ziek realized he was about to be a lot smaller. "B-bro, I wanna go to the bathroom now!" he whined as he held his arms up, a habit he knew that would get his bro to help him and hold him. The goat kept crying as he shrunk down to toddler age with his tiny little penis pissing onto his shirt now, the goat rubbing his eyes with paws, even if he knew the pee would sting his eyes. "Oh, alright little guy, even if yer kinda too young for a bathroom" he grinned and grabbed the little goat by his arms and whisked him away to the bathroom, a few patron watching the half naked goat in his brother's arms and just assumed a baby had a accident and assumed the older goat's undone pants were for other reasons, when they got into the bathroom, Aaron took his little bro into one of the bigger stalls and sat down with the little goat 

Aaron smiled at his little brother, a bit of deviousness in his eyes as he pulled the soaked clothes off of Ziek leaving him as nekkid as the day he was born and his tiny little bits on display for his loving brother. "You're my perfect little boy" he said, picking up the tiny goat and putting him smack down between his chest and throbbing cock, wiping away the boy's tears as he presented his dick to his bro, his favorite toy. Ziek cheered up slowly as his tiny paws wrapped around the huge cock in front of him, jacking off the older goat. "Yeaah, good bro" he rubs and pets his little bro as he keeps going, his paws quickly getting slick with pre, his older brother's fat nuts produced plenty for him. Aaron bleated and moaned as his bro, his breaths becoming quick and heavy as Ziek get going faster and faster on his dick, his unwieldy little paws and shorts arms making it difficult, but Ziek wanted to make his big bro happy.
 
Ziek whimpers as he feels himself start to tinkle all over his big bro’s dick, the toddler unable to control his piddle any longer, but this only turned on his older brother even more who couldn't control himself any longer. He pressed his little bro tightly against his cock as he bleated loudly as his throbbing cock added to the wetness between the brothers as he started cumming, shooting thick cum all over his little bro and the older boy himself. Until Ziek was covered in goat cum and Aaron was very well spent. Aaron yawned and turned Ziek around and held him close to his warm musky chest "Love you Ziek" he held the goat tight as Ziek put his thumb in his mouth and started sucking, snuggling his bro as they held each other.
