Nathan was rather short, even for a mouse his age. Most of the other kids he met towered over him. He and his dad had a weekly tradition of sorts, every Saturday after they did some chores around the house they'd go to Nate's favorite fast food place. They'd get some food and after they ate Nathan would play in the play area. 

Often times the play area would be pretty barren, only one or two kids around at most. That was fine with Nathan though. He much preferred his imagination to other, real people. He'd make epic stories in his head and act them out in real life. Today was no different, when the little mouse came running into the enclosed play area there were no other kids to be seen. As soon as he got his shoes off he was already in the maze of tubes and slides.

As the mouse boy scampered about his father decided to put in a pair of earbuds and listen to some music whilst reading a newspaper. He didn't even notice when a new kid walked into the play area. 

Steven was much bigger than Nathan. Although that only made sense, he was a year older than the cub and he was naturally going to be taller since he was a cat. All that added up and he was at least 6 inches taller than the mouse boy. 

As soon as Steven heard Nathan running around up in the suspended tunnels he knew he had to go make a new friend. He slinked his way up the twists and turns of the play set, hardly making a sound. Moments later, Nathan turned around and was caught of guard by the midnight black feline before him. 

"Hey there! Nice to meet you, I'm Steven." The cat said cheerfully, holding out his hand, an invitation for the mouse boy to shake it.

"Wow, you surprised me! I didn't hear you come up." The mouse boy sheepishly said before reaching out and shaking the waiting hand. "I'm Nathan, people call me Nate though." 

"Nice to meet you, Nate." Steven said with a smile. "Wanna play a game?"

"Sure. What game?" Nate asked.

"How about... Tag?" Steven suggested.

The mouse boy nodded, "Okay, who goes first?"

"Uhh... You." The feline said, turning and crawling as fast as he could though the tight tunnels as soon as he finished the statement.

The two of them went back and forth chasing each other for a long while. At some point Nate's father finished his newspaper and took an earbud out, listening to the loud footsteps and laughing from the two boys. He was happy his son seemed to find a new friend. After he was satisfied that his little boy was alright he put his earbud back in and started watching a TV show.

The mouse boy came to a halt in front of a clear plastic dome facing a large window, he could see right out into the parking lot, and in theory, anyone could look up and see him.

"Hey, uhh could we maybe do something else for a bit?" He asked in-between deep pants.

"Sure, I know a game we could play..." Steven said. "But you wouldn't be able to tell anyone, not even your mom or dad."

"What kind of game?" The younger boy asked.

"I can show you, but you gotta promise not to tell anyone."

"Okay..."

"Pinky swear?" Steven held out his pinky.

"Pinky swear." Nate replied, wrapping his own finger around the other's. 

Their digits' embrace was comparable to a legal agreement in the younger boys eyes, and that's all Steven needed to play the "game" with him.

"Alright. First, I need you to pull down your pants and underwear." Steven explained.

"What? Here? Why?" Nate started questioning.

"Do you trust me?"

"I guess... But-"

"Then pull em' down. I promise you'll like this game." Steven cut him off mid-sentence. 

"Okay." Nate unsnapped and unzipped his jeans and shuffled both his pants and underwear down.

He reclined back against the clear dome and peered over his shoulder at the nearly empty parking lot. His mind was aflutter with nerves. Suddenly he felt something soft nudge his groin. He turned back and saw his feline friend had reached down and started to rub his sheath. He had never been touched down there before. He himself barely touched that spot, only to clean or to scratch an itch. Quickly his pink member began to pop out, summoned by the loving touches from the black feline.

"Oh gosh." Was all he could muster in response to the new forms of pleasure he was feeling.

As he finally grew to full mast Steven pulled his own pants down, his own barbed cock already erect. He scoots forward to position his barbed rod next to the mouse boy's. He wraps his hand around both members and begins rubbing. Squeaks and gasps dribble from the mouse's mouth. The two of them are squirting pre-cum, lubricating them and allowing Steven to jerk faster and faster. Nate's tail twitches and shakes involuntarily whilst Steven's swishes slowly, clearly he's more used to this kind of pleasure. The mouse cub begins feeling a fullness in his balls and tries to warn the other boy. 

"I think I'm going to-" 

His cum sprays upwards, soaking their cocks and coating the older boys hand. Steven stops his fervent wanking and brings his hand to his maw, slurping up the ivory fluid. He purrs quietly, enjoying the taste and the look on the boys face.

"Wanna try something else?" He says with a smirk.

"Uhh sure. Okay." Nate says, still in his post orgasm haze.

"Alright, just turn around." Steven instructs.

Nate slowly spins around, now facing out the window, he had completely forgotten he was in public, his face gets flush at the idea that someone could've seen him in this indecent state. Steven then grasps at the base of the boy's tail, lifting it and exposing his puckered hole. He dives in tounge first, dragging his rough tounge up and down the entrance. A surprised squeak is heard from Nate. His refractory period already past, his cock returns to it's full glory. Steven's free hand makes it's way to the anattended mouse meat, stroking up and down. The feline then thrusts his tounge inside the cubs backside, squirming back and forth.

After giving Nate's hole a good licking he pulls away and rubs his cock. Making sure the mouse's cum is evenly lubricating his rod. He then takes aim, positioning himself between the mouse's ass cheeks. He eases in gently, inch after inch reaches into the well lubed hole. Nate shudders at every minute movement. Soon Steven has hilted himself. He slowly pulls back out, the soft barbs scrape against the boys insides making him moan in pleasure. The cat boy stops when just the very tip of his cock is left inside the boy. He thrusts forward much faster than the first time. He then gets into a steady rhythm, in to the hilt, out to the tip. Soon his balls slap against the boys taint, making a quiet clapping sound. Nate's moans get louder and louder, he covers his mouth with his paw, embarassed to be doing such naughty things in public. He begins thinking of what someone might think if they saw him like this. Just as he really thinks about his situation the constant pressure on his prostate gets the better of him and he begins cumming for the second time, both today and in his life. Hot, sticky cum puddles below him on the tunnel floor, the hot cock thrusting into his ass keeps a constant stream of cum drizzling out. His ass constantly contracting in spasms also brings Steven over the edge. Cat cum floods the boys bowels, painting his insides as white as his fur. Steven grunts and purrs with satisfaction. Yanking his cock out he spews the last few shots onto the floor as he bends down and begins licking the cub's leaky backdoor, slurping at his own baby batter.

Once his pucker is properly cleaned the boys pull up their pants.

"Wow. Thank you for showing me that." Nate said.

"Yeah, it was pretty great wasn't it? " Steven said, tucking his softening penis away. "I gotta go right now but... Will you be here next Saturday?"

"Yeah, totally!" Nate said excitedly.

"Alright. See you then." Steven turned and slipped away down out of the playset.

As Nate watched his new friend leave, he was happy he would be seeing him again.
