Mark woke up first and casually played with Jacobs slobbery tongue as he slept with his mouth open, Mark felt himself getting erect under the sheets as he rubbed his fingers along his brother's tongue. Using his other paw he started stroking his penis coxing it from his sheath. Jacob woke up suddenly with a small yelp Mark was still holding his tongue and quickly let go “ sorry bro I couldn't help it” he opened his mouth and offered his own tongue but the boys were interrupted by their mom “ guys it's breakfast time!” Jacob quickly grabbed his brother's tongue and licked it. “ I'll play with it when you get back” Mark nodded, unable to speak while his brother held his tongue.
After breakfast the boys got ready for school looking forward to going to daycare afterwards. Mark and Jacob could hardly concentrate on school as they thought of all the fun things they were going to do with Noah and Kody. Finally after what felt like forever the bell rang and they ran out to the bus almost tripping over themselves. They settled down on the bus sitting in the back so they could plan” so I wanna be his underwear for 24 hours and then change back but I don't wanna end up at his house with his laundry” The boys rubbed their bulges through their pants “ I know! I'll change into a random pair of underwear and you trade him! That way he brings them back tomorrow” Jacob nodded." Sounds like a good idea bro just make sure you change into something cute”. They continued to play with themselves getting stiff and squirting in their underwear.” Change into mine and I'll trade him” Mark grinned and closed his eyes as he shrank down his fur becoming a spider man printed fabric his mouth the little flap in front. Jacob quickly grabbed his former brother and stuffed him in his backpack.
Mark was stuffed into darkness feeling himself being wadded up. Jacob rode the rest of the way occasionally rubbing his crotch. The bus arrived and Jacob grabbed his backpack and ran inside searching for Noah. He found him playing inside with some trucks and quickly joined him “ hi” Noah looked up and smiled showing off his sharp teeth “ wanna play?”
“ Sure”
The boys played together pushing the trucks around until Noah looked at Jacob “ let's go potty” the boys entered the bathroom and shared a urinal in the corner. Both boys pulled their pants and underwear down completely as they aimed into the porcelain urinal “ wanna trade underwear? Just until tomorrow yours are really cool but I have Spider-Man ones” Noah peed while examining the offered undies " ok Jacob smiled and started peeing giggling as he crossed streams “ just make sure you bring them back or I'll get in trouble. After peeing the two traded undies.
Mark felt himself being pulled up the boy's slim legs and around his waist, the feeling of the boy's sheath and balls being cradled in his fabric body was intense beyond measure. He felt the young panther's balls resting where his lower jaw would be and his sheath brushing against the roof of his mouth, he could taste the drops of pee that he hadn't shaken off. Darkness enveloped him as Noah pulled up his pants and went back to playing with Jacob. As they played Noah's penis started peeking out of his sheath and rubbing against his underwear, he used his paw to adjust everything, smearing his glans across Mark's mouth.
A few hours later the boys went to the bathroom again, harsh light flooded Mark's view as Noah pulled his pants down, keeping his underwear up and tugging his flaccid penis out of the flap, with his penis now hanging out of what should be Mark mouth he started peeing while playing with himself. Mark watched the yellow stream flowing from the flaccid cock protruding from his mouth. He could see the urinal and his brother peeing as well. “ How do you like my undies?” Noah looked down “ I like them! Spider-Man is my favorite one” Jacob wagged his tail and started playing with his penis as it got stiff in his paws “ do you squirt?” Noah looked at Jacob and then his penis “ what's wrong with your penis?! It's all weird looking”. Jacob showed Noah his penis “ yours doesn't get stiff?”
Noah knelt down and closely examined Jacobs penis “ you can touch it”. Noah didn't hesitate; he wrapped his paw around the boy's shaft and held it “ it's really warm!”
“Can I touch yours? I wanna see it get stiff like mine”. Noah nodded and Jacob started playing with the boy's soft penis.
“ What do you mean by squirt?”. Noah asked as he played with Jacobs penis “ I squirt stuff when I play with it”
Noah tugged and squeezed Jacob's penis “ can you show me?” Jacob nodded and kept playing with Noah's penis “ I'll show you with your penis, look your starting to get stiff”. Noah looked at his own penis “ wow! That feels weird”, the boys kept playing with each other's penises uninterrupted standing next to a urinal full of pee.
Mark watched everything from his viewpoint. He saw Noah's penis stiffen up and eventually point straight up” that's so cool! It feels really weird” Jacob released Noah's penis and gently pulled his own from Noah's grip” if you like that just wait until I teach you how to squirt, it works better if your penis is slippery I use drool” he opened his mouth and slobbered over his penis while Noah watched his bright green eyes wide “ that's icky” he did the same spitting on the floor and his underwear first “ whoops”. After getting themselves sufficiently lubed Jacob wrapped his paw around his own penis “ now just start stroking it rubbing the tip causes you to squirt faster so be careful”. The masterbated together panting lightly, their tongues hanging out their soft moans echoing off the tile.
Noah suddenly jerked, his slim body twisting as he gripped his penis tighter his breathing increased and he trembled as he squirted for the first time, clear whitish fluid spurted from his penis aching across the gap and splattering on Jacobs borrowed undies “ s-sorry!” Noah gasped still gripping his penis staring at it in awe” Jacob grunted as he climaxed squirting his own load across Noah's undies covering his brother's fabric face. The boys stood together panting and giggling softly still holding their penises “ you squirted so much more” Jacob looked at the attractive young panther” the more times you do it the more you squirt, just gotta wait for it to recharge an older boy showed me”. After catching their breath the two cleaned up washing their paws and left the bathroom trying not to look to guilty.
Mark felt Noah walking around each step causing his balls to bounce and his sheath to sway rubbing gently against his fabric. He could taste his brother's cum mixed with Noah's. He needed release and he needed it now but that wasn't going to happen he would spend the next 24 hours pressed against Noah's penis and there was nothing he could do about it.
Noah got home and went to his bedroom, getting undressed for bath time he hid the undies under his pillow. Mark felt himself wadded up and stuffed under Noah's pillow while he bathed. A short while later he could hear him getting ready for dinner. It felt like forever until he heard the door open and close followed by a paw grabbing him. “ Why did he want to trade undies?” He sniffed the underwear pressing the soft fabric against his nose unaware that he was pressing Mark's face against his. Noah's paw slipped down and started squeezing his sheath teasing his penis out eager to repeat his earlier experience. Wrapping his paw around his hardening shaft he started stroking quickly, stopping to spit into his paw and returning his attention to his penis. He stroked himself while sniffing the underwear, he opened his mouth and started licking the underwear before nomming on it. For at least the second time in his life Mark found himself in another boy's mouth. He loved it the warmth, the wetness feeling Noah's sharp teeth biting down on his fabric body but causing nothing but pleasure.
Noah tugged and squeezed his penis breathing heavily through his nose while he chewed on the underwear. Pleasure filled his young body and for the second time in his life he climaxed. A creamy white liquid spurted from his penis surprising him causing him to let go. His penis now free spurted his load out across his sheets and stomach before stopping. Noah laid flat on his back his mouth agape as the pleasure ebbed away. Noah caught his breath and sat up still holding the underwear in his mouth, he watched his penis slowly soften and slip back into his sheath. He took the underwear out of his mouth and put them on giggling at the feeling of the warm wet fabric. He licked his cum from the sheets before flopping back down and covering himself with his blankets. Mark was again enveloped in darkness as Noah fell asleep.
