Mark got home panting heavily it was to hot outside for fur. Closing the door behind him he closed his eyes and shifted back into his normal self, he laid down on his bed still sporting a massive erection his balls aching for relief. He started playing with himself moaning softly. He stuck his tongue out licking his lips as he edged himself squeezing and twisting his hand around his sensitive intact glans “ fuck I wanna jerk off with you I'm so fucking horny” Mark nodded and released his penis and sat up. Making a face like he was blowing up a balloon he closed his eyes and exhaled.
Jacob was released from Marks mouth growing rapidly returning to his body but still covered in his brothers drool. Mark stopped blowing as Jacob detached and flop onto the bed a raging erection between his legs “h-holy fuck!! That was so cool you really need to try!” He used some of the drool covering his body and started masturbating “ I'm so fucking pent up”. They masturbated together lost in their own pleasure grunting and groning softly a teenage musk filling the room. They ejaculated simultaneously aiming their penises at each other “ cum fight!” they covered each other in copious amounts of cum soaking into the sheets and mattress. Laying down together with a wet slap they cuddled and kissed.” So you want me to be your tongue? Or maybe something else” he played with Jacobs penis holding it loosely. Jacob shrugged “ it's your choice bro”. The boys snuggled and kissed before falling asleep.
They woke up later that night and snuck into the kitchen for a snack, going back to their room with a box of cookies they flopped together on the bed “ let's be little again” Mark suggested Jacob nodded and they closed their eyes and regressed into twin 7 year olds. Giggling softly they sat down on the floor naked and munched away on the cookies, bellies full they started playing with the toys scattered around the room pushing the trucks around making engine noises the boys played for hours until predictably they needed to go pee.
Dashing off to the bathroom together they gathered around the training urinal that they had begged their parents to keep. Grabbing their penises the boys peed together holding hands and giggling almost missing the urinal in their youthful excitement. With empty bladders and a little urinal full of pee the boys took turns dipping their toes in the warm yellow liquid. “ Awww it's getting cold” Mark splashed his toes around “ I wish we had more” both boys smiled and faced the bathtub closing their eyes.
The bathtub rapidly filled full of pee, the semi bitter tang filled the room and both Jacob and Mark jumped with delight before climbing inside the liquid level even with their chins. They splashed around laughing and trying to dunk each other in the warm yellow liquid, they had made sure their parents wouldn't notice anything especially the smell. They continued to play for hours adding and subtracting as needed until daylight appeard in the window. “ Crap we need to go to shool, they got out and dried off “ let's stay little! I wanna go back to elementary school I'm tired of highschool stuff”
Back in their bedroom they got dressed and went to breakfast. “ Morning boys how did you sleep?” they sat down with bowls of cereal and started eating, showing each other the chewed up messes in their mouths when Mom wasn't looking “ we slept good mom do we have to go to shool”?.
“ Of course you do honey you need to get all smart”
They finished breakfast in silence “ ok you two go brush your teeth and hurry up!” They went upstairs and brushed each other's teeth bubble gum pink toothpaste drooling streaming from their mouths. Clean teeth and faces the boys reluctantly went to the car dragging their backpack. It was a quiet ride to school with Mark and Jacob continuing to make faces at each other as they began to accept that they were really kids again. Mom dropped them off at the turn around leaving them to play with their friends before school.
They found Nathen and joined him on the play structure swinging from the monkey bars and sliding down the bumpy slide they enjoyed the wonders of youth until the bell rang. The boys went inside and found their desks. Class was fun for a change they had a really good teacher and of course Mark and Jacob were the best students in the class even if they were cheating slightly. Lunch time rolled around and after eating PB&j the boys ran out to the playground desperately in need of releasing their boundless energy.
They ran across the field racing each other to the play structure and finding a hiding spot to catch their breath “ I love being little again!”
“ Yeah we just need to be careful not to forget we're supposed to be older”. They played around running and chasing the other boys from the class until they couldn't. Going to the class room they stopped by the boys bathroom and picked out a urinal. As he was peeing Mark turned to face Jacob casually peeing on the floor “ I wanna be a urinal!”. Jacob faced his brother joining him in peeing on the floor “ a urinal? Can we even do that?”
“ You where my tongue for a entire day I'm certain we can do anything” he emphasized anything “ just think about boys peeing on you all day just think of the penises! You'll get to see all the penises, I'll try it tonight with our urinal just in case so you can change me back”. Mark and Jacob washed their hands and went back to the classroom for the rest of the day.
The boys got home and immediately went to their bathroom standing in front of the plastic urinal shaped like a frog with it's mouth open a flaccid rubber tongue sticking out to collect accidents and large eyes on top for decoration.” So you really wanna be a urinal” Mark nodded and rubbed his brothers prepubescent penis through his shorts “ yeah I do”. He closed his eyes and concentrated making sure he was able to remain conscious. His naked body started shrinking and molding into the tough green plastic his mouth stretching out and his tongue growing larger, his eyes moved to the top of his head and became rigid as he finished his transformation. Jacob put his hand on former brother and was relieved to be able to hear his voice “ this is so weird! Hurry up and pee I'm super thirsty” his voice was slightly muffled as Jacob pulled down his pants and undies little kid style and aimed into the urinal.
The sound of water on plastic reverberated in the bathroom as Jacob filled his urinal brothers mouth the yellowish liquid flowing down the back of the urinal in pooling in the collection bottle. Jacob continued to pee and pee smirking as the bottle quickly overflowed and his pee started filling the base getting closer to the lips, putting his hand on the plastic he started talking to Mark “ having fun yet” he heard Mark's voice in his head “ yessss yesss OMG I can't wait to try it with the urinals at school” Jacob finished up and stood in the bathroom half naked talking to Mark “ want me to empty you?”
“ It's actually fine I just feel like I'm full in a good way can you try rubbing my tongue?”. Jacob knelt down and started playing with the flaccid rubber tongue hearing Mark's soft moans “ can you taste anything with this”
“ Yes I can” Jacob started kissing the rubber tongue his face inches away from the gallon of pee. He stopped quickly and pulled up his pants “ mom and dad are home, I'll be back after dinner and don't worry I'll drink plenty of water” turning off the lights he closed the door and skipped down the hall where his parents greeted their only child.
Mark sat silently in the darkened bathroom his plastic belly full of pee his rubber tongue still damp with saliva. It was weird not having to breath or be able to move. He could feel the pee cooling inside his reservoir the smell of it was making him excited but unfortunately the urinal didn't have a penis for Jacob to play with when he got back. As darkness set outside the window Mark waited patiently now filled with cold smelly pee when the door opened and dad entered “ what is that smell?” He came over to the urinal and inspected it “ I've told him that he can keep this silly thing if he empties it!”. He picked up Mark and carried him carefully to get toilet and opened the drain squeezing and twisting Mark's penis as he did. Mark felt the pee emptying from his body as Dad held him over the toilet, he put the empty urinal down with a dull thunk and stood there “ fuck it” he unzipped his pants and pulled out his thick cock and aimed at the target printed on the back. A solid stream of pee splashed loudly against the hallow plastic and into the reservoir, Mark tasted his dads pee as he peed unaware into his other sons gaping plastic maw “ I can see why he likes this thing” business completely he shook his penis off sending drops across the bathroom and put his penis away and left the bathroom.
Jacob came in a little while later and stripped naked quickly and hurried over to Mark while clutching his crotch “ gotta go gotta go gotta go right now, I drank lots of water at dinner bro just for you” he stood in front of me urinal dancing from foot to foot before releasing his stream. Hot clear and slightly salty Jacobs pee arced into Marks awaiting maw. The young boys pee mixed with their dad's and started to overflow again this time going over the plastic edge and spilling into the tile “ yesss victory” he placed his hand on the plastic “ bro Dad emptied me and then peed in me I saw his penis! It's way thicker than ours are” Jacob giggled and played around with his aim but keeping it within the plastic maw “ he told me he emptied my urinal what was it like?” His stream slowly stopped and he sat down on the floor leaning against Mark “ it felt super good my penis is the drain thing” Jacob shifted slightly and grabbed the drain plug “ oh you mean this?” he played with the drain stroking the short plastic pipe before standing up and struggling to carry the overflowing urinal to the shower “ time to play”.
Jacob opened the drain sticking his fingers under the stream of urine as Mark was emptied again, oh it's still warm” with pee covered hands he started playing with the drain spout again rubbing it slowly and poking a small childs finger inside. Mark moaned softly as Jacob teased him” please I can't cum” Jacob licked the back of the urinal “ I know neither can I my balls haven't dropped yet” he fondled his brothers plastic penis while playing with his own penis. As much as he tried he just couldn't get hard and ended up tugging and squeezing his flaccid penis gently pulling his foreskin down. He gave up and got up walking over to the bathtub and turned the water on “ wanna change back” he put his hand on his brother and nodded stepping back. Mark closed his eyes in his mind and concentrated, a green tinted boy started peeling away from the urinal his plastic skin softening into soft flesh with a gasp he started breathing again as he fully separated from the plastic he stumbled across the bathroom floor looking back at the urinal and smiled “ that was cool I'd definitely do it again but at school” the boys climbed into the bathtub and washed each other before drying off and brushing their teeth and getting dressed in matching paw patrol underoos and pajamas, climbing into separate beds for the time being they allowed their parents to tuck them in. “ Did you boys remember to empty your urinal” Jacob nodded “ we emptied it mommy it's all clean” the kissed them both before turning off the lights and closing the door.
The boys waited until Mom and Dad went to bed before Jacob joined his brother on the upper bunk “ what should we be next? I definitely like being little even though our penises don't work” Jacob kissed Mark and humped against him “ yeah not being able to get erections it kinda frustrating but being little again is awesome”. The boys kissed and fondled themselves before breaking away from the kiss but keeping their hands in their underwear. “So what should we try next? Another body part? Something else intimate? Both boys yawned and struggled to stay awake “ we'll….think.of.something” Mark fell asleep followed shortly by Jacob.
