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 rather barren, only one or two kids around at most. That was fine with Nathan though. He much preferred using his imagination, making epic stories in his head and acting 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 couple years 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. As Nathan rounded a corner he was hit hard in the chest. He landed on his back with the wind knocked out of him. As he was trying to catch his breath Steven scurried over to him and roughly pulled the pup's shirt off. He stuffed the cloth in the boys mouth and tied it behind his head, effectively gagging the winded little mouse. The feline grips onto the boy's ankles and roughly pulls him further into the play area, stopping at a clear dome facing a large window out into the parking lot. Tears stream down Nathan's cheeks as he sobs into the cloth in his mouth. 

As the feline let's go of his ankles he tries to crawl away, but he's stopped in his tracks when Steven sinks his claws into the cubs back. The poor mouse squeals into his gag, hardly a sound makes it past. 

"Get back over here." Steven says, raking his sharp claws down the boy's back, making his white fur turn pink as a small amount of blood seeps from the lacerations.

The mouse cub stops resisting and goes mostly limp, silently sobbing. He is pulled back to the plastic dome and positioned on his hands and knees, facing out to the nearly empty parking lot. Steven yanks at the cubs pants and underwear, not bothering open them. In one movement the boy's rear end is exposed. Nathan is shocked at the sudden change of pace. Only his family had seen him in such a state, and now this bully has exposed him, in a public place no less. His crying only grows worse, a constant stream of salty tears run down his cheeks as he looks out onto the empty tarmac, hoping someone will see him, hoping someone will save him.

The larger boy grips onto the mouse's tail and lifts it roughly. Steven knows he could probably get himself inside the cubs without any prep, but that'd be quite the hassle. Especially the blood. He bends down and quickly begins licking at the boys pucker. Nathan is appalled that someone would do such a gross thing to him.

Nate's father gets done reading his newspaper and takes an earbud out and listens for any signs of something bad happening to his son. Silence. He assumes that the pup was just playing quietly like he normally does. He soon takes out his phone and begins watching a TV show, oblivious to what's happening to his son.

Steven thrusts his tounge into the boy's rear end, spreading his saliva as deep as he can. The attention Nathan's backdoor is getting causes his groin to stir, the poor cub's getting hard. Pre-cum beads at his tip. After he's done lubricating Steven pulls away and pulls down his pants. He grabs hold of his cock and takes aim. In one thrust the battered little mouse is impaled on his barbed member. He screams into the makeshift gag, just enough noise escapes to rev up the sadistic cat even more. The squeaks of pain are music to his ears. 

Steven yanks his cock out and thrusts back in to the hilt. As his thrusts grow firmer and faster his work gets easier, although not because the cub is relaxing. As Steven looks down his member has become a dark shade of red. His little toy has started bleeding. 

"Shit, was hoping this wouldn't happen." Steven says, not disappointed or sorry, just annoyed. "Guess there's no point in stopping now."

The feline doesn't let up, in fact, he starts thrusting even harder than before. Every time he gets thrusted into Nathan feels a jolt of pain and pleasure. Apparently he's a natural born buttslut if he can take this much pain and still be rock hard. Eventually it gets too much and his little balls quake as he shoots his load all over the floor, and Steven could tell what happened.

"Did you really just cum, you little slut? Guess I shouldn't feel so bad about breaking you in this hard." He says. "Well, I'll be there soon too, just you wait."

The spasms of the mouse's tight ass massage Steven's kitty cock. After one great thrust he explodes and hot cum flows. Excess leaks around his rod, his batter turned pink by the cubs blood. He pulls out and sprays his last few shots on the boys ass and back. Blood and cum drips from Nathan's battered ass, it drips down to his emptied balls.

"That was a nice lay, bitch. Maybe I'll see you next week." Steven says as he tucks his softening penis into his pants.

The mouse curls up into a ball and sobs silently as Steven quickly scales out of the play set and puts his shoes back on and leaves. Nathan's dad didn't even know he was there at all.
