Mortimer and Jeremey had a lot in common. They grew up in the same neighborhood, both were fruit bats, and they shared the same birth month though in different years. They also had a lot of differences; Mortimer was reserved, anxious, thoughtful, inquizitive, inventive. Jeremy was outgoing, confident, self centered, and well, he at least had a passing grade in school. Jeremey was a year older, and made sure to remind Mortimer any time he could. It was all in good fun, as the two were best friends since before they could remember. 

Jeremy and Mortimer were headed to the town park. They had a smaller park in their community, but this was a better one with fields for sports and a large nature trail. It even had a small concession stand, though the prices were a bit jacked up. The two had hit a convenience store on the way, grabbing their favorite slushie beverages with the money they received from their recent birthdays. Both of them were born on the same month, with Jeremy being a year older. Only a few days ago Jeremy had his 14th birthday party, however he and Mortimer liked to get together to celebrate their shared birth month in a smaller celebration, just the two of them.

They were dressed in usual bat clothes. A top that was open on the sides for their wing membranes, with string at the bottom that tied to their lower clothing. Both boys wore something similar to kilts, but much lighter and airier. This made gliding a bit easier, especially for newbies to flying like themselves. They just referred to them as bat-skirts since the bat name was hard to pronounce.

As they walked down the street, Mortimer wondered what Jeremy had planned as these outings usually ended up with some kind of mischief. He kept quiet, straw in his mouth as he sipped the mango flavored slush. Jeremy did enough talking for the both of them.

“I was flying around the other day, and I think I found a great hiding spot in the forest around here. The grass is tall and I don’t think there’s a trail leading to it. Fliers only.”

Mortimer retorted, “You know you’re not supposed to fly outside of the community. It’s dangerous with power lines and getting lost. What if you tear a wing?”

“Oh it’s not a big deal, I was only flying a little. And look”, Jeremy says as he sweeps his wing across the entrance of the park, “No power lines at the park. It’s all underground like at home.”

Bat’s tended to live in smaller communities on the side of town, separate from the rest of the population. As the only mammal with wings and flight, they had things a little bit different at home. Bats had only migrated to this part of the world in recent generations, and there was still a bit of adjusting needing to be done. Everyone was treated equally on the surface, but infrastructure-wise things could be difficult for a bat over here.

Mortimer sighed in defeat. It wasn’t that he couldn’t debate this, it was that Jeremy would never give a fair debate. “Just promise we’re only flying a little, to the spot. Please”, he whined.

“Just to the spot, and back of course. Now hurry up and finish your slushie so we can fly.”

Mortimer nodded and sipped a little faster, only a little as he didn’t want the dreaded brain freeze. They still had a little bit more walking, going across the main field of the park to the head of the trails. By the time they reached the other side, both of their plastic cups were empty. They discarded them in the bins nearby and prepped for flight.

Being young and inexperienced, they both made sure they had a lot of room to gain height. Their wings were still developing, and not as strong as they could be. Their wings were an extension from their arms, a membrane extending down their sides. Their ‘hands’ had 3 free digits, with the other two extending to form more of their wing. Outstretched, their hands extended to the usual length of mammals with wings continuing a foot further.

A running start and a few flaps were all they needed to get off the ground. Mortimer followed Jeremy, careful not to follow too close. He looked down at the trees below anxiously, all those branches would be terrible for his wings should he fall. His mind clouded with visions of pierced wings.

“Watch out!”

Mortimer swooped to the side, barely avoiding Jeremy who had stalled midair. He nearly began to barrel but corrected himself and pulled back up to Jeremy.

Jeremy paid no mind to Mortimer’s near miss. “See the bend in the river? There’s a clearing under the trees there, you have to fly low near the water to get under. Just dive for speed and glide when you’re close to the water.”

“A dive?! You didn’t say anything—“

Too late. Jeremy had already wrapped his wings around himself, plummeting headfirst towards the river. As he got close he spread his wings in an instant and rotated horizontally to glide right above the water. Moments later he disappeared under the leaves of the forest.

Mortimer stared in disbelief. This was definitely against the rules for young bats. But he couldn’t just leave, Jeremy planned this for them. He took a deep breath, closed his wings, and fell like a rock. It wasn’t until falling for several seconds he realized his eyes were closed, and that wasn’t going to end well. He opened his eyes, the river growing in size at an alarming rate. He opened his wings and began to rotate but he was too late. The claws of his feet hit the water, causing drag. He began to slow. Panicking he flapped his wings, but he was so close his wingtips were grazing the surface. With the shore coming up he was much too low to safely swoop up above the ground.

Mortimer closed his eyes and wrapped his wings around his body, diving into the water. Everything was cold and dark, up and down were just mere ideas. ‘Wait, my eyes are closed.’ He opened his eyes and quickly oriented himself, his rear end touching the bottom of the river as his head emerged from the surface. A quick look around found him just at the shore. A few more feet and he would’ve dive bombed the ground.

Jeremey rushed over, wading through the water and crouching next to Mortimer. “Are you okay? You took dive a little too far.” He pat his friend on the back, Mortimer coughing out some water. 

Cough cough, “I almost died! Do you think I’m okay?!” 
“Sure. Not a scratch.”

Mortimer stood up, water dripping from every inch of his body and soaked clothes. “And my clothes are all wet. I can’t fly now.” He walked over to dry land, spreading his wings to check for damage. After finding no holes, he closed them around his body and shivered. “And I’m cold”, he whined. 

Jeremy wrapped a wing around his friend, “You’re such a baby. I guess a year makes all the difference.” The older bat was enjoying this a little, it was fun to tease Mortimer over little things. 

Mortimer pulled away as he began to sniffle, walking to a large tree and facing it. “You’re so mean. I wanna go home.”

“Well you can’t, not until your clothes dry. My clothes are a bit wet too. We have to hang out for a bit.” Jeremy walked around Mortimer, getting to the tree he was facing. A grin spread across his face as he plucked a low branch. “You know, your clothes would dry quicker if you hung them on a branch.”

“You’re just saying that to trick me. You can’t fool me again.” Mortimer shivered again as a cool breeze from the river blew past. 

Jeremy put a wing around the smaller bat again, “I won’t steal your clothes this time. I promise.” 
This time Mortimer didn’t pull away. “Promise promise?”
“Super duper promise. I won’t touch them.”
“…Fine. But you gotta stand somewhere else until they dry.” Mortimer began untying his shirt from his skirt. 
“Sure. I’ll stay all the way ovee—“ Jeremy ran to a tree across the clearing, “—eeer here.”

Satisfied with the distance, the younger bat slipped off his shirt and hung it on the tree. His slim boyish body not yet going through ‘the phases’ as his parents said it. He unclipped the buttons on his skirt, sliding it off his waist and placing it on a second branch. His slim body continued downwards, accented by a round tush under his red boxer briefs. The wet undies clung to his skin and fur, showing the shape of his butt rather prominently. When he turned around Jeremy was staring at his loins, which the wet undies also clung to. 

Mortimer brought a wing in front of himself quickly. “Don’t be weird like last time. I’m not taking these off, either. So don’t ask.”

Jeremy was quick to reply with his sly voice, “I wasn’t doing anything weird. We’re both boys— I mean guys. You’d dry faster if you—“

“Not happening. Now if you stop being weird we can still play.” Mortimer looked around the woods, through the dense trees. Around the clearing was tall grass, making the only clear way here to be from the river. As he looked around he dropped his wing. 

Jeremy walked over, but not too close to the tree Mortimer’s clothes were on. “Yeah. Let’s play. Hmm…” He slapped the younger bat’s arm and ran away. “Tag, you’re it.” He ran to a rather thick tree, a large maple, and around it. 

Mortimer spun around, reaching out at the fleeing bat but missing. “No fair, you didn’t give me a chance.” He ran after Jeremy to the large tree, standing on one side with Jeremy on the other. Each one waiting for the other bat to make a move. Mortimer walked around the trunk but as he caught a glimpse of bat, so did Jeremy, and he ran away. No matter which way Mortimer went, he couldn’t get around quick enough. 

The younger bat thought for a bit, looking at the huge tree. ‘If I can’t go through or around, what about over?’ He gripped the trunk with his claws and pulled himself up, and while bats were known for their flying, they also were decent climbers. He climbed into the branches and peered down at his friend, who was busy looking around the tree instead of up. 

Jeremy was getting worried, wondering why his friend wasn’t coming around the tree anymore. He slowly began to walk around the trunk, “Morti? Are you done?” As he walked around half the tree his voice suddenly gained a quiver. “Morti?! Where are you?” He completed a lap around the tree, then turned around and ran around the other way. “Morti! This isn’t funny! Morti please come out. Morti?…”

Mortimer watched his confused friend from high above as he climbed under a branch. He climbed out several feet, hooked his feet around the branch, and right as Jeremy walked under him he swung down hanging by his feet. 

“BOO!” He yelled as his face swung right in front of Jeremy. 

Jeremy yelled and stumbled backwards, falling on his backside. Mortimer laughed, he got him good. 

Jeremy’s heart was pounding in his chest, his breathing heavy and his claws gripping the dirt. It took a few moments for the adrenaline to wear off. “That wasn’t funny. I thought you got lost or something.” He pushed himself from the ground, walking over to Mortimer hanging from the tree. They were about face to face. 

Mortimer was still laughing softly, unable to hide his huge smile. “That was hilarious. You were so scared. Hahaheeeeeee… ah. I feel better now.”

Jeremy crossed his arms, pouting silently. “You’re a butt, you know.” He tried to act all tough and somber but he couldn’t stay mad. His arms slowly uncrossed and his frown faded away, then he looked back up at his hanging friend. “I just thought… never mind.”

The hanging bat knew he meant well. “So what do you wanna play now?”

“We could splash our feet in the water, but we don’t want to get too wet or we’ll have to wait longer. We could draw in dirt…” Jeremy thought long and hard until his eyes lit up. “Let’s wrestle, like we did when we were pups. You’re already dressed for it.”

Of course Jeremy was referring to the wrestling they saw as TV as pups. The guys were dressed in just their underwear. Jeremy and Mortimer would undress to their briefs and wrestle like on TV. 

“Really?” Mortimer asked, letting out a sigh. “As long as you don’t pull my underwear like before.” He pulled himself up, grabbing the branch with his arms and flipping around before dropping to the ground. As he hit the ground, he felt a little jolt in his midsection. 

“It was on accident.” Jeremy rubbed the back of his head, looking away. 

Mortimer’s voice went flat, “It happened almost every time.”

“Fine. I won’t pull your underwear.” Jeremy undressed, tossing his clothes near the edge of the clearing.

Mortimer was watching, not intently staring at anything, and gasped when Jeremy pulled off his skirt. “Dude, leave your underwear on. I don’t wanna see that.” He looked away, finding the leaves on the trees suddenly very interesting.

Jeremy turned towards Mortimer and laughed, pulling the waistband of his black briefs. They blended in against his black fur. “I have underwear, it’s just hard to see.” He let go of his undies, causing them to make a snap against his waist.

Mortimer took another look, stepping closer. Sure enough, where he expected to see too much detail looked rather smooth. Impossible to make out any detail in the shade but he definitely wasn’t naked. 

“Dude. You look naked. It’s weird. You’re weird.”

“Whatever you say. If you’re too scared to wrestle just say ’chicken’.” Jeremy put his hands at his hips and flapped. 

“Never!” Mortimer lowered his stance like they did on TV. He stepped closer. “Fight me.”

Jeremy followed along, getting low and close. “On three… one… two… three!”

Mortimer was quick, extending his legs to launch himself forward. His head crashed right into Jeremy’s gut. Jeremy dug his claws into the dirt, while grabbing onto the younger bat’s head, pushing it to the side. As he tried to turn his claws were stuck in the dirt on a tree root, causing him to fall backwards and let go. Mortimer fell forward, landing on his hands and quickly turning back on all fours. He pushed himself up and ran at the fallen bat, jumping with his wings extended. Jeremy’s eyes went wide as the younger bat came at him, he braced his wings over his body.

Mortimer landed on top of the wing wrapped bat, his own wings on either side of the subdued bat. He pressed his body down, not allowing any sort of escape. “Do you give up?”

Jeremy wriggled around, trying to roll to the side. After several seconds of failing to make progress he lowered his wings from his face, which was only a few inches from his friend. They could feel each other’s heavy breathing. “Yeah. You win. Umm…” Jeremy pulled up his knees, followed by Mortimer rolling off to the side. They both sat up with Jeremy keeping his knees up and Mortimer sitting with his legs extended, leaning back on his hands.

“What’s up?” Mortimer continued, looking at his friend with concern. 
Jeremy looked down at the ground. “Oh nothing, “He paused for several seconds, “I just need a minute.”

Mortimer thought about it, ‘He’s usually very talkative, and doesn’t keep secrets.’
“You sure? You look sad, did I hurt you?”

“No!” Jeremy snapped back quickly, “Sorry. I just, it’s embarrassing.”

“Embarrassing for you? That’s new.” Mortimer stopped staring and looked at the canopy of leaves above them. “You can tell me anything, you’re my best friend you know.”

“I know but you said not to be weird and I’m actually trying.”

The two sat in silence for what seemed like a while, the breeze blowing from the river through their small clearing. Nothing but the sound of water flowing, the rustling of leaves in the breeze, and a few bugs. As Mortimer shifted his eyes to the flowing river he suddenly felt a strong urge to pee, which his body had mentioned before they wrestled. He pressed his legs together, shifting them up and down slowly. He opened his mouth to speak but Jeremy spoke first.

“Umm, I’ll tell you if you promise to not get weirded out.” Jeremy put his knees down and sat like his friend.

Mortimer paused, pressing his legs together. The feeling went away. He looked back at Jeremy. “I promise.”

Jeremy sighed, still unable to make eye contact with anything but the dirt. “When you were on top on me I uh, started feeling funny, and I uh…” His voice lowered to whisper, “I got a boner.” His cheeks gained the faintest hue of pink against his black fur.

Mortimer shifted for reasons other than embarrassment, his urge coming back stronger. He willed it to wait a little longer. “That’s okay. It happens I guess. Are you still…?” Mortimer’s eyes shifted downwards between Jeremy’s legs, the fabric was smooth with a small ambiguous bulge near the middle.

“Nah. It went away after a minute. Are you checking me out?” Jeremy had finally looked up from the dirt. 

It was Mortimer’s turn to blush, looking away. His urge to pee was getting worse and he reached down to press against his crotch. “Mmmf no. I was just curious. Sorry, I really gotta pee. Can we go back now?” He stood up in anticipation of leaving, having to lean over and give himself another reassuring grab. 

Jeremy stood up, and after hearing his friend’s need he found that he had to go a bit too. “Why? We can just go here. No one’s around.”

“You’re around, and you’ll peek.”

“Nu uh, and they look the same anyways.”

“See! You’ve peeked before.” Mortimer began to swing his hips, his pert butt pushed out as he bent over. He couldn’t keep a hand off his crotch either. “Mmm I really gotta pee.” He felt really full and the urge wouldn’t go away even as he kept hold of front. “I’m getting dressed and leaving.” He slowly walked over to the tree that held his clothes, rubbing an arm against them. They were just about dry.

He pulled his skirt from the branch, letting go of himself to pull it around his hips. It felt a bit tighter than before, and as he clasped it on the urge to pee suddenly spiked up. He danced in place and he retrieved his shirt, sliding it over his head and quickly wrapping the strings to his skirt.

Mortimer turned around to find Jeremy just pulling his shirt on as well. “Hurry please.” Jeremy was dressed and made his way to the center of the clearing. 

Jeremy tilted his head towards shore, “It’s a little tough with the low clearance.” He looked up and down the dancing younger bat in front of himself. “You sure you can fly like this? I wouldn’t want—“

“Yes! Let’s go.” Mortimer’s reserved nature was waning as a more pressing nature took hold. He gave himself one last reassuring squeeze, as he couldn’t hold himself if he wanted to fly. He ran towards the shore, flapping his wings gently. He couldn’t gain too much lift or he’d hit his head, but he needed to be airborne before he touched the water. He made a last second leap right at the shore, pulling himself up as hard as he could. The river was luckily long and clear above it, so he could take more time gaining height.

As he rose above the trees and went into a glide, he felt a tremble between his legs. His boyhood felt really tingly, and was tensing a bit. He also noticed a slight dampness in his undies. He didn’t want to think about it but taking off was a bit intense on the body. ‘It’s smooth gliding from here. No more leaks. No more leaks.’ 

A few minutes later Mortimer saw the edge of the treeline and the buildings in the park. He lowered his altitude until he was just above the grass in a small soccer field. He pulled himself back and landed on his feet with a thud.

PSSHH

He quickly grasped his crotch and bent over, stopping the leak. The landing was also tough, he remembered. Moments later another thud was heard, it was Jeremy. Mortimer was too busy holding himself to say anything. He looked up, not at his friend but for the nearest restroom. ‘Gotta pee gotta pee. Where is it?’ He scanned around and found a building near the edge of the field. Without another thought he began to walk over, keeping a hand on himself. 

His mind was cloudy, filled with all these uneasy feelings. He could feel his bladder was filled up, heavy above his crotch. It kept sending little waves, pushing towards the exit. He felt these weird spasms from his boyhood, as if it too was trying to refrain from the bladder’s desire to empty. He pushed it aside for a moment, looking up, the building was just a minute away. Just a minute until he could undo his skirt, pull down his undies, and…

A sudden wave of panic overwhelmed his thoughts, he felt a shift down below as the tension in his body lowered. He gripped himself tightly as he felt his insides spasm, like everything was being pressed over and over. He felt it pushing through his tubes, an inch every spasm. Closer and closer to the exit until— Mortimer’s eyes widened and he stopped moving.

PSSHH

He felt it flowing— no, spraying into his undies. He tensed his muscles but it barely slowed. He willed it to stop, and for what seemed like too long nothing responded. He couldn’t feel anything but the wetness spilling into his undies. It was only a few seconds though, and the flow slowed to a trickle then stopped. He felt the fullness of his bladder again, this time with soaked undies clinging to his fur and skin.

Mortimer knew he had peed himself, but didn’t want any more to happen. He took off, running towards the building. He kept one hand pressed against his wet crotch. The building was so close, just a few more seconds. As it got closer he could feel it again, a sudden lack of tension. A few seconds later the spasms began. Pump pump pumping liquid through his body. His boyhood tingling in ways he had never felt before. He was so close in multiple ways.

He ran around the side of the building, towards the door, grabbed the handle and— It wouldn’t budge. No turning, no pushing. A trickle entered his underwear and he squeezed his tip as he looked up at the door.

FIELD MAINTENANCE BUILDING A

“No, no…” He backed from the door just as Jeremy came around the corner. He felt the tension all slip away and with nothing left, he let go of himself and stared at the ground. “Jeremy… ahhh!” The sudden warmth in his undies made him gasp.

Jeremy looked at Mortimer standing there, then at the door. “Mortimer? We can go—“ He was interrupted by the sudden rushing of liquid into his friend’s underwear, making a rather loud splashing sound as it pooled in his undies before flowing down his legs. He followed the sound, not seeing much until a stream of liquid flowed down both of the younger  bat’s legs and onto the ground. Jeremy waited silently, watching the stream as it flowed into the ever growing puddle. 

Mortimer wasn’t sure how long he stood there, all he could feel was emptiness as the flow of warmth traveled down his legs. It was such a relief, he didn’t even care that he was completely peeing himself right now. Right in front of Jeremy too. He closed his eyes and took deep breaths, letting it all melt away. 

Jeremy put a hand on Mortimer’s shoulder, startling him. “I think you’re done peeing. Um, are you?”

Mortimer concentrated on the feeling down there and realized he couldn’t feel anymore pee flowing out of his boyhood. Not a sound to be heard either. “…Yeah. I’m done. I’m sorry.”

This surprised Jeremy, “Sorry for what? You couldn’t hold it. It’s not your fault.”

“I wet myself like a pup. I look stupid. I ruined our birthday.” Mortimer felt himself begin to choke up, tears welling in his eyes.

“You didn’t ruin anything. Things happen… I’m sorry, actually, for making you so uncomfortable you didn’t want to go in the woods.” Jeremy squirmed at the thought, backing away from Mortimer. “Actually, I kinda have to pee too. Do you mind if I…?”

Mortimer shook his head.

Jeremy went around the corner, finding a nice row of bushes. He undid the top part of his skirt and pulled down his waistband, freeing his length. He let out a content sigh as his water flowed freely into the bushes. Like Mortimer, there was a lot of liquid waiting to get out and it took a good minute for it all to flow into the bushes. Relieved, he put himself away and returned to his friend.

He found Mortimer bent over, hand under his skirt. He was about to ask when he saw red undies being pulled down his legs. They were much darker than earlier, absolutely soaked with pee. The younger bat stepped out of them and threw them in a trash bin. He didn’t notice Jeremy’s return until after.

“Uhh, I can explain.” 

“Mmhmm, no need. Though maybe I’ll join you~” Jeremy said playfully.

Mortimer replied in kind, “Don’t be weird, weirdo~”
