Fighting his anxiety, Timmy walked up to the dinky looking house, double checking the address his friend gave him. The 14 year old mouse had never been to this neighborhood which was considered unsavory by the standards of his quaint little town. Which kind of made sense, considering why he was here. It was a fairly well-kept secret among the boys in his school that the girl who lived here had a thing for young teens, and for 40$ she would make your dreams come true. 
With that in mind, he put on a brave front and rang the doorbell. The wait seemed to last forever, until the wooden door swung inward, revealing a young lynx girl wearing a t-shirt and little else standing beside the second cage-like door. The shirt was of some band Timmy never heard of and was probably meant for a rhino since it came halfway down the feline's thighs and the neck hole was so large it hung off one shoulder. Still, it managed to expose a good deal of her figure, showing her patterned tan fur and the cream-colored expanse trailing down from her chin and presumably ending somewhere further down.
"Can I help you kid?"
The question snapped Timmy back to reality and he blushed, realizing he was staring. Looking up at her face he noticed a small smirk curving her lips, the feline apparently satisfied at having caught him staring as her eyes sized him up. He thought she had a very pretty face, with a mop of shaggy teal hair between two long, heavily pierced ears, the tips ending in pointy tufts of black fur. She also had three piercings in one eyebrow, and a ring through the middle of her bottom lip and a leather collar with a paw print medallion on it.
"I... uhh that is my friend Andy told me to come here and... I mean, he told me that you and him..."
"Tell you what, you wanna finish that sentence inside? I'm kinda underdressed here." Suzy said leading the nervous kid inside and closing the doors behind them. The kid went silent as he took in the child-inappropriate room. A gory hack & slash game was on pause on the TV, it's soundtrack still blaring through the speakers. A console controller was on the coffee table, along with a small bong and several half empty liquor bottles. The walls were covered in music posters as well as prints that ranged from suggestive to lewd. Suzy supposed it wasn't a conventional boudoir, but then again she wasn't a conventional girl. She watched the boy take it all in, until his eyes settled on the large Rottweiler that had trotted into the living room, no doubt wanting to see what the commotion was about.
"Don't worry, that's just Brutus. Here, let him sniff your hand." She said and the boy extended his arm, trying not to show just how scared he was. Brutus just gave his hand a few good sniffs and started to pant happily, extending his head towards his mistress who obliged him by scratching behind his ear.
"See, he likes you! That's good, 'cause I only hang out with boy's he likes. He's my big, strong bodyguard and he's an excellent judge of character." She said, noting that the boy felt more at ease now, having apparently passed some test.
Truth is, the rottie liked anyone Suzy liked. And Suzy liked boys like Timmy. And she seemed to have a steady supply, ever since one kid from Timmy's school came to her house trying to score some weed. Deciding that the kid was too young for pot, she sent him off with a blowjob instead, and told him that if he ever wanted something more to show up Monday evening with 40$. He did, and even though Suzy swore him to secrecy she wasn't surprised to find more shy, horny boys beating a path to her door. Which was fine by her. Mondays were her night off at the bar where she worked, and her roommate and frequent fuckbuddy always spent Monday and Tuesday with her boyfriend. That left her alone with Brutus, which neither of them minded. Before the boys came along she would usually spend her time off on all fours letting the Rottweiler fuck her brains out. Since the dog missed their special private time she made it up to him a few months back. She and Jane had gotten high and were fooling around when she called Brutus over and let him eat her out. After seeing the lynx cum around the Rottie's huge tongue the doe decided to let him taste her as well, but drew the line at letting Brutus fuck her, reasoning that she wasn't really cheating on Darren unless she was taking someone else's dick. Despite that twisted logic she seemed to have no problem jilling off while the dog mounted Suzy. Well, if things don't work out with Darren, maybe I'll get her a collar of her own. Still, first things first...
"So, what's your name kid?" she asked, plopping down on the couch and patting the space next to her.
"Uh, Timmy." He said, sitting down.
"Well Timmy, I'm Suzy, and contrary to what you may have heard I don't bite. So there's no need to be so nervous."
"Oh, sorry. I guess I'm just kinda shy..." Timmy trailed off watching Brutus who'd curled up by their feet.
"Ah, well I know a cure for that!" Suzy exclaimed, grabbing a bottle of Jack and taking a good swig. Before Timmy knew what was going on, she'd grabbed him by the back of his head and pressed her lips to his. The mouse felt a stream of liquor enter his mouth. Suzy broke the kiss and Timmy gulped the scotch down, trying not to cough and sputter.
"There ya go, stud! Feelin' more relaxed now?"
"I think so..." Timmy replied in a daze. He'd never had hard liquor and both the booze and the kiss had left him a bit lightheaded.
"So Timmy... ever have sex with a girl before?"
"Uh, no. I had a girlfriend but we never... took it that far."
"U-huh. Was she a mouse like you?"
"Yeah."
And probably just as shy and nervous. "Ever see a girl naked?"
"Uh, no." Timmy said, blushing at the lynx's questions.
"Well, then that's a good place to start!" Suzy said, pulling her shirt off and revealing she wasn't wearing anything underneath, not counting a conebell piercing in each nipple and a stud in her bellybutton. She rested her arms on the back of the couch and leaned back, letting Timmy get a good view. Her breasts were only B-cups, but looked bigger on the short, slim feline. Timmy took in the sight of her perky mounds, his eyes moving down along the expanse of creamy fur, over her trim belly and slim waist right between the lynx's legs, where the cream gave way to pink. Suzy smiled, her eyes locked on the bulge growing in the boy's pants.
"I think you might be more comfortable if you took your clothes off, cutie." she said, drawing Timmy's attention to her face, and then to what she was looking at.
All nonchalance forgotten, the mouse boy rushed to get naked. Suzy was grinning as she played with a nipple piercing with one hand, her other one rubbing gently between her legs, which guaranteed Timmy's eyes weren't on the task at hand. After an unimpressive striptease, the lynx once again patted the spot next to her.
"Now come sit next to me. And feel free to touch anything you like."
Timmy tentatively raised his hands and cupped the feline's perky breasts. Suzy thrust her chest out and relaxed into his touch, gasping slightly as the boy gently flicked her piercings. Good instincts, kid! While Timmy's eyes were glued firmly to her boobs, she reached out between his legs to see what she could look forward to. Not bad, she decided. The kid was about 6" and already hard as a rock. It wasn't exactly what she was used to, but it would suffice. She gave his shaft a few more rubs and squeezes before she decided foreplay was over. She had plans for this kid and they went beyond a simple hand job. And it's not like it takes a lot to get me wet...
She threw her arms around Timmy's neck and drew him into a deep kiss. While the kid was still getting his bearings, she plopped back, laying on her back on the couch with the startled mouse boy now on top of her. Getting over the surprise of being dragged down, Timmy positioned himself between the feline's legs, freezing in place when he felt his tip nudge against something warm and wet. Suzy gave the kid a few moments to say goodbye to his virginity before giving him her best "Fuck me!" look. It proved to be all the mouse boy could take and he drove himself inside with a gasp almost as girly as her own.
Suzy gave the kid some time to adjust to the new sensations, nibbling on his ear lightly as her hands explored his body. After a while they settled on the boy's butt, each grasping a cheek. Suzy had plans for the kid and he would need to get used to attention being paid to his bottom.
"C'mon lover, give me all you got!" she husked into his ear.
Even though he admitted he was a virgin, Timmy was determined not to look like some clueless kid and started humping as hard as he could into the gorgeous feline underneath him. She seemed to enjoy it, moaning into his ear as her hands grasped his butt, pushing him in with each stroke. The whole thing felt better than he ever imagined - her warmth, her smell, the sounds she was making and the amazing sensation of her pussy squeezing around his shaft. Her preoccupation with his rear end seemed a bit strange, but he didn't want to say anything. For all he knew, that was normal, and it wasn't actually unpleasant.
Suzy found herself enjoying the boys amateur but spirited thrusting, and even though the sounds she was making weren't faked, they were slightly exaggerated. Still, they served their purpose and spurred the mouse boy on, making him grunt and pant as he pistoned in and out of her wet snatch. She slipped one hand to her pussy, giving her slit a few strokes, but more importantly getting her fingers wet. She nuzzled the boy's neck as one hand spread his cheeks apart. Her slicked finger touched the mouse's pucker for an instant before slipping in. As expected, the kid was somewhat startled by having his ass invaded, but Suzy was ready for this.
"Mmmm, don't stop! Fuck me!" she said in a needy, desperate voice that would make a porn star blush.
Timmy wasn't sure what to do - on one hand the finger slipping further inside him was uncomfortable and embarrassing, but the feline writhing under him while he pumped his shaft in and out of her slick cunny was too good to pass up. He decided to ignore the digit that was now thrusting in and out of his virgin button and thrust as hard as he could into the lynx girl, trying to recover some masculinity.
Well, this is a good sign Suzy thought as she continued to violate the boy's pucker. It seemed the more she pumped him the more he pumped her. She was pleasantly surprised at the mouse's stamina, and as his young cock pistoned in and out of her soaked pussy her moans were becoming less and less fake. Brutus also seemed to notice the change, and hopped up on the couch excitedly. It was exactly what Suzy had been waiting for. She withdrew her finger from Timmy's pucker, one hand still gripping a cheek while the other grabbed his tail and held it out of the way. The dog had now straddled the boy, and before the mouse could react Suzy locked her lips on his. The dog was now humping at the air, trying to get into position when Suzy braced her feet on the couch and lifted her crotch, serving up the boy's backside to the humping canine.
She saw the boy's eyes open with surprise when he felt the dog's tip poking at his button, and then stretch open even further as the Rottweiler drove his cock inside him. He screamed into their kiss as the canine began to hump the mouse's no longer virgin ass, not even noticing the lynx's pussy clenching around his own shaft as Suzy came at the sight of the mouse being mounted.
"Aaaaah! W-what..." Timmy broke the kiss and tried to form the words while Brutus was pounding his behind.
"*huff* Well, you didn't expect him to just lie there while someone screwed his bitch, did you?" Suzy asked with a sinister smirk.
"Y-you mean... you...?"
"That's right. Collared and knotted! Speaking of which, you might want to relax. He's not getting off until he's filled you up!"
Timmy buried his face in the feline's neck to hide his embarrassment. Suzy's finger hadn't felt bad, but didn't come close to preparing him for the dog's rod. The thick red shaft drilling into him felt painful at first, but as Brutus began to fill the mouse's hole with pre and Timmy tried his best to relax the sensations became more uncomfortable than painful. His pucker still hurt, stretched taught around the red monster buried inside him, but the canine cock seemed to reach parts inside him that Suzy's finger didn't. And every time it hit that spot inside him, his cock twitched and he felt Suzy's pussy clench around him. After a while, his pained grunts seemed to turn into embarrassingly feminine squeaks as Brutus bred his behind, panting happily above him. He felt Suzy lift his face up and kiss him deeply and hungrily, obviously turned on by the mouse's predicament.
"Now c'mon lover, you've got a bitch of your own to breed!" she said teasingly, smiling at the dazed expression on the boy's face. Still, it seemed to work, the mouse making fast, shallow thrusts into her while the dog continued to violate his backside. The room was filled with the sounds of their fucking, the mouse boy's pucker now almost as wet as Suzy's snatch.
Timmy's cheeks were now burning more than his bottom was. He tried to focus on Suzy as much as possible, on her breasts squished against his chest, her breath tickling him as she nibbled on his collarbone, and her warm folds wrapped around his shaft. The other sensations were far too embarrassing. The pain had faded, and Timmy was surprised and ashamed of the pleasure he was feeling from the Rottweiler's vigorous mating. He could feel the dog's growing knot bump against his opening on every thrust, and the dog's large sack smack his own smaller one, ready to fill him up at any moment. To make things worse, every time he pulled out of Suzy, he thrust back into the dog's humping, which made him feel like... well, a bitch.
The sight of the boy above her, biting his lip as she screwed his eyes shut, was almost enough to make Suzy cum again. Still, she knew she needed to keep it together for a little while longer. While she nuzzled the mouse's neck, her hands traveled down his sides and back to his butt. She kneaded and groped the boy's cheeks to try to get him to relax, feeling the dog's pelvis smack into him on every thrust. After a minute or so Timmy seemed to relax a bit, and Suzy was ready to take advantage. She timed it carefully and spread the mouse's cheeks wide apart just before the dog humped into him, allowing Brutus to bury his knot in the boy's ass.
Timmy had gotten used to the felines hands on his rump and was surprised when he felt himself stretched wide open, and even more surprised when the dog's knot popped past his ring. His instinct to clench came too late and only served to trap the massive organ deep inside him. The tip of the cock now seemed to press right against that special spot, and as he felt the knot balloon up and the dog's thrusts slow, he drove himself as deep as he could into the lynx, grunting as he squirted his seed inside her. Her pussy clenched around his cock as she came, while his own ring clenched around the beast buried in his rump. As he came down from his orgasm, Timmy became aware of a warm sensation in his rear, as the dog started to pump his seed inside his newest bitch.
Suzy basked in the sight of the deflowered mouse, nuzzling his ears as he let out weak little gasps every time the dog spurted inside him. Not wanting Brutus to feel left out, she scratched him behind his ears while the canine lovingly licked his mistress' face. After a few minutes like that, she felt Timmy start to get hard again inside her, and she ground her hips against his crotch, making the sensitive mouse squeak. About five minutes later, Brutus started to tug his shaft out, and she felt Timmy give a week spurt inside her as the dog's knot slipped out of him, followed by the rest of the canine's cock, as well as what seemed like a pint of cum. The kid collapsed on top of her and she let him lay there for a bit, while her fingers probed around his stretched pucker, still leaking the dog's seed. 
Once Timmy got his strength back she helped him clean up. After the mouse got dressed, she noticed his hand reaching into his pocket.
"Keep it, kid."
"But, I thought..."
"Well, I don't feel right charging anything if I had a good time. And watching Brutus pump your rump definitely qualifies!" she said with a wink.
"Uhm, thanks?"
"You're welcome kid. And don't be a stranger!" she said as she saw him out. Suzy was glad that after all she did to the mouse, she could still make him blush.
