Jacob and Mark walked out of their bedroom slightly awkwardly with their massive new equipment hanging between their legs. They had to learn how to walk again. They joined their parents in the living room “ how was your day, did you find anything cool at the mall?” The boys sat down trying to hide the bulges in their pants “ nothing interesting just walked around and tried to talk to some boys but nothing really interesting” their dad smiled “ no boyfriends yet? You two will get someone, trust me”. They watched TV with their parents for a while before dinner arrived.” Didn't feel like cooking tonight so we Dashed it, got our favorite Chinese food”.
After dinner the boys went back to their room and stripped down “ahh that's better damn nuts were getting pinched” Jacob fondled himself as his massive testicles shifted in their sack “ his horse cock emerged from his sheath dripping pre * that's so cool* Mark nodded and started playing with himself and soon the brothers were fully erect “ wanna suck each other or just masturbate “ Mark was staring at Jacob's horse cock” I'd love to have that in my mouth”. Jacob smiled and licked his lips” let's change back into anthros again “ the boys closed their eyes and soon became a horse and a dog” that's better now I have a bigger mouth”. The brothers laid down facing each other's penises and without hesitation started licking and slurping sloppily, soft moans filled the room as they tested out their new bodies. Drool and precum dripped from their mouths and pooled on the floor soaking into their fur as they lost themselves in their pleasure. With a grunt and a whinny Jacob climaxed shooting his massive load into his brother's muzzle, the K9 swallowed as much as he could but some still leaked out from around his lips and joined the growing puddle underneath the boys. The sensation of his brother's cum in his mouth was too much and he climaxed himself filling his brother's mouth with hot fresh doggy cum. The boys continued to empty their balls until they broke apart rolling onto their backs penises still fully erect as they panted heavily drooling cum and drool “ h-holy fuck” that was incredible!” Jacob could only nod in agreement” the boys slowly collected themselves and sat up watching their penises slowly deflate and return to their sheaths.
The cuddled in the puddle casually licking each other until Mark gently held his brother's tongue “ you remember that one story we read about, that one about playing inside someone's mouth?” He looked embarrassed, as embarrassed as a dog could look “ Jacob smiled and nodded , Mark let go of his tongue “ how do you wanna do it?” Jacob thought for minute “ how about I shrink down small like about the size of a lego figure and you let me inside your mouth” Mark agreed “ just one thing first” he closed his eyes and concentrated before opening them again “ made my mouth super clean for you see” he exhaled forcefully allowing his brother to smell his cinnamon fresh breath “ you can do anything you want except poop”. Jacob closed his eyes and started shrinking down smaller and smaller until he was no bigger than a lego figure, looking up at his brother towering over him he was slightly frightened as the horse lowered his hand and let him jump on.
Carefully raising his tiny brother Mark stopped in front of his mouth and smiled, parting his lips allowing his brother to see, listening carefully he heard him begging him to open up. He opened his mouth and stuck his tongue out until it was resting on his hand. He could feel his brother's light footsteps scamper the length of his tongue and he carefully closed his mouth. Jacob's paws sank into the soft flesh of his brother's tongue as he scampered inside gleefully, he looked around the large drippy mouth and sat down leaning against Mark's teeth. He took a moment to admire what was happening, he was inside his brother's mouth! His penis was now fully a slightly painfully erect and he couldn't stop himself from scooping up some saliva and using it as lube. He started masturbating, closing his eyes and moaning softly as his brother inhaled and exhaled his breath flowing around him. It didn't take long before he climaxed again shooting his load across his brother's tongue. Mark moved his tongue around pressing Jacob against the roof of his mouth as he swallowed the drool and cum that was pooling between his teeth, relaxing his tongue he opened his mouth slightly as Jacob explored carefully looking down his rippling throat he started peeing giggling as the stream disappeared into the darkness. Bladder and balls empty he climbed up and sat down on Mark's lips leaning against his front teeth.
Mark was standing in front of a mirror with his mouth wide open as he masturbated his massive horse penis ozzing pre, Jacob watched as his own penis grew stiff and he started playing with it. Mark was breathing heavily through his mouth and Jacob had to brace himself as he masturbated again. With a whinny and a gasp Mark climaxed, his thick cum splattered across the mirror as he emptied his balls for the third time. Jacob humped against his brother's lips and soon climaxed himself squirting his load across his brother's teeth. He climbed up on Mark's lips and got his brother's attention. Mark held his hand under his mouth and spit his brother out before carefully putting him on his semi erect penis “ damn you tasted good bro.” Sitting in a puddle of spit Jacob smiled and wagged his soggy tail before carefully climbing down and returning to his normal size” that incredible! You need to try it!”
Mark looked at his brother covered in his drool “ I'll do it just make your mouth really clean”. Jacob closed his eyes and soon opened his mouth showing off “ nice and clean and ready for a tiny horsy to play” Mark closed his eyes and shrank down before climbing up on his brother's paw” Jacob smiled and opened his mouth wide allowing his tongue to flop out sending drops of drool splattering everywhere. He raised his paw carefully and let Mark enter his gaping maw. Mark carefully walked across his brother's slippery slobbery tongue his hooves barley making a depression in the soft flesh, he ran a hand across the sharp k9s breathing heavily his penis fully erect and pointing straight out, he stopped at the back of Jacob's throat and held on to his teeth looking down into the darkness before looking up and seeing the rippled roof. Turning around he walked over and slipped in between his teeth and cheeks rubbing his erection against the wet surface moaning softly as he did. He humped against Jacobs cheeks as his brother's drool pooled at his feet, he could tell that Jacob was holding back from swallowing and he loved it. His hooves splashed as he humped faster and faster getting closer to climax. He whinnied and climaxed, squirting his thick creamy cum across his brother's teeth. He flopped down on Jacob's tongue panting and played with himself casually fondling his empty balls. Jacob opened his mouth, flooding it with light and allowing Mark to see. Jacob was holding his penis and playing with his balls while facing the cum splattered mirror, his tongue slid forward and Mark had to grab his teeth to stop himself from falling out. Jacob was panting heavily, his hot breath flowing in and out of his mouth as he brought himself closer to climax. He moaned loudly, vibrating Mark as he climaxed squirting loads of doggy cum over the mirror. He let go of his penis and reached into his mouth, Mark jumped into his hand and rode it out. After gently placing his little brother in the large puddle of cum Mark shrank down and joined him playing in the still warm cum.
