As far as Penny's babysitters went, Rufus was an outlier. Usually they were eighteen to mid-twenties, and that was simply the typical age for a babysitter as far as Mr. and Mrs. Mardas were concerned. Rufus came to them recommended as a charming and responsible babysitter who happened to be a forty-year-old bachelor. So far, they liked him a lot. More importantly, so did Penny.

He and Penny got along while her parents were still around. She showed him her bedroom and he thought all the posters of singers and bands tacked up on the walls were awesome. He saw the video game console in the living room and threatened to teach a thing or two in a popular mascot-based fighting game. Mr. and Mrs. Mardas left with smiles on their faces, confident that their little angel was in good hands.

"Right. Yeah. Half sausage, half pepperoni, all mushroom. Thanks." Rufus set the phone back in its cradle, turned, looked at the pink birthday cake on the table. It was half-eaten already, its cheerful if not crookedly-written message - HAPPY 11th BIRTHDAY PENNY - mostly illegible now. Colorful butterflies in mid-flutter dotted the cake - sweet crunchy candies, not icing. Rufus started to lift up the clear plastic bowl set as a makeshift lid over it when a paw touched his hip. He looked down to see Penny and smiled.

"You're gonna spoil your appetite," the girl teased. She grinned up at him.

"When you get to be as old as me, you can do what you want," Rufus replied with a wink. "And what I want is to eat a slice of this pink cake." He winked and added, "Happy late birthday, by the way."

Without hesitation, in fact so suddenly that the quip seemed rehearsed, Penny asked, "How about you eat my pink slice instead?"

Rufus dropped the lid and stared at Penny, mind reeling with disbelief [i](no way she said that no way no how)[/i] and wild attempts at rationalization. The tall kangaroo looked down at her, a crooked smile on his handsome graying snout. There was just no way he had heard what he thought he heard.

"Say again, honey?" Rufus affably asked her.

"My pink slice," Penny affirmed, her smile innocent and girlish. She pulled up her skirt. No panties. "Or instead of eating me, you can fuck me and call it my birthday present."

Rufus stared at her. He had fucked more women than he could count, fucked horses on four legs and other barnyard critters, but never a little girl. "Let's just-," he found himself unable to look away from her young cunt, stared at it the way he tended to stare at accidents on the road, "let's just put the brakes on that. I don't know what stuff you kids are into these days but when [i]I[/i] was growing up, pedophiles went to prison."

"Oh, they still do," Penny said dryly. She let her skirt drop, closed the gap, grabbed for Rufus. Her paws felt underneath his shorts and for a few long seconds, Rufus let her touch him. He only pulled away when her fingers brushed his scrotum and it dawned on him that he was enjoying her attention.

"Penny!" he cried. "Behave yourself!"

"What?" Penny asked, her smile innocent, practiced so very well. "Were your balls [i]on top[/i] of your dick? That's weird."

"It's a marsupial trait, including us kangaroos. The scrotum is-," Rufus found himself explaining it again; he was used to going through it with women who had never seen it before. "You're a little kid!" he bleated. "And I'm a-, I'm an adult."

Penny snickered. "Oh [i]ga-a-awd,[/i] sometimes this is fun, but right now? Right now I just want some [i]dick.[/i] So just fuck me, and I won't tell my parents you fucked me anyway."

A cold lump formed in Rufus' throat. He swallowed hard. "You wouldn't do that," he weakly protested.

"Nah. I really wouldn't. But come on! Just fuck me. You're, like, the fourth guy this week to put it inside me." She bent herself over the table, pulled up the skirt. "Come on. Don't make me beg. Just fuck me, old man."

"Old man," Rufus scoffed. Just on principle he wanted to fuck her now, show her what a so-called old man could really do. In a much baser part of his brain he just wanted to fuck her, period. Pedophile thoughts were not new to him; he had simply never acted on the impulses in all his years of babysitting. Rufus pointedly ignored the fact that all it took was offering herself for him to be a pedophile. He just thought about the time he'd fucked a horse; [i]might as well get my dick wet if she's up for it.[/i] His shorts grew tight as the possibilities filled his mind, fears and pleasures running together like one primal instinct until he couldn't separate the two. A shudder passed through his aged body.

"All right. I'll fuck you," the kangaroo conceded. He unzipped his shorts, slid them down, boxers too. He caught Penny looking back at his groin, studying his strange prehensile penis. This brought a grin to Rufus' lips. The placement of marsupial testicles was always the first thing remarked upon, the strangeness of the kangaroo penis second. "Never seen a kangaroo cock before?" he coyly asked.

"Nuh-uh," the girl admitted without pause. "It's all [i]wiggly.[/i] That's weird."

The kangaroo patted her hips. He brought his cock to the lips of her pussy. Young and snug, its tight lips were a fine use of the tapered shape of his penis. He said as he pressed against her, "You'll like it. Everybody likes it once they give it a chance."

Penny grinned. "That's what I say to all the guys I talk into fucking me."

Rufus grumbled. He rubbed his wriggling, writhing cock against the lips of her freshly eleven-year-old sex, ground it broadside between the lips with their thin fur and warm embrace. Beneath him Penny cooed and Rufus was flush with some masculinity - a bit of power snatched back from the domineering girl.

"C'mon, Rufus, stick it in," Penny urged. "Or are you scared?"

The kangaroo fixed her with a smile. "That kind of talk might work on the young bucks. Me, kid, I think with my big head too."

Penny smiled back. She effortlessly ruined him: "Yet you're about to fuck a little girl. Score one for the little head."

Rufus did not believe himself to be a world-class wit, but he thought he could outsmart a child at least. Now he was beginning to feel like the idiot coyote chasing the clever roadrunner. "Shush," he grunted to her as he pushed into her young vulva. The tight, wet pink inside was like a sleeve of velvet. Both babysitter and his charge crooned with pleasure, Penny more noisily than Rufus.

"Mm, good god," breathed Rufus, paws molesting the girl's hips. "Might be the tightest girl I've ever had."

She tittered. One leg flamingoed off the floor, the toes curling. "I bet I'm the tightest pussy ever for a lot of guys."

Rufus was blushing. His hips moved with slow care. He could be energetic, his legs could help him fuck like a piece of industrial equipment with a pecker attached, but Penny was so small and delicate.

Like she could read the kangaroo's thoughts (or perhaps, Rufus acknowledged later, she was just used to men treating her like she was a porcelain doll), Penny deadpanned, "You can go a [i]little[/i] faster than that. Not my first time getting crammed."

"Right. Yeah, sorry," Rufus murmured, and he suffered some honest-to-god embarrassment. Of course Penny was used to being railed - and wasn't he a fool for thinking otherwise? So he put himself into a quicker gear, started to use some of the power in his vaunted legs. His muscular tail swished, swayed. He wasn't about to tripod on it, he didn't think little miss Mardas could take that kind of a pounding, but he gave it to her harder, faster, fucking her like he'd fucked more than a few virgins in his lifetime.

"Ooh, damn, yeah! Rufus, that's it," Penny whined. Her foot fell back to the floor. She held primly to the counter, pink-glossed claws glinting like gems under the bluish florescent glow. "Mmm, that's the [i]shit,[/i] and that weird dick of yours feels good."

Rufus was smiling, grinning really. Another convert to the wonders of kangaroo meat, and this one was starting off young. His paws slid up her body, over flanks, against the grain of fur. He asked her quietly, "Want me to touch those little tits? I do love me some nipples."

"Nipples are all I have," Penny teased. She pushed herself off the counter, stood proudly with legs straight and back inclined, her entire body angled stiffly like a boomerang.

The kangaroo's paws crept under her shirt. Fingers felt across her nipples, little pink buds under creamy tan fur. He couldn't detect even a hint of a breast; if not for the pussy wrapped around his member, he might as well have been fingering a boy.

"Mosquito bites," Rufus tutted as he pinched the nipples. He tuned the stiff nubs and playfully remarked, "Come on, I can't get any stations to come in."

"Shut up," Penny giggled. "Shut u-u-up, you old nerd."

Rufus smiled. He kept going, kept fucking, kept twiddling. The girl writhed for him, cooed, moaned like the preteen whore she was. Vaginal secretions oozed around his penis and pressed into his fur, left him hot and sticky as if he were a pastry.

"Mm, mm-mm, god," Rufus cooed. He leaned back on his tail and let it rock his hips into her. The small round curve of her butt wobbled as he struck it; her butt was the only thing halfway girly about her otherwise boyish body. He thought of a MILF of a bear he used to spend his days with and wondered if Penny Mardas would one day blossom into a plump mama bear too. Selfishly, he hoped not. He hoped Penny would be so fuckably young for all time.

Penny huffed for Rufus. She was pawing at the counter, every breath heavy and hot. "Ah-, hah, god, that feels so good," she puffed. "Gonna-, gonna cum if you keep fuckin' me..."

"Yeah, cum for me, little girl," Rufus growled, his voice full of the adult seduction he used on his adult partners. With Penny it came as naturally as breathing. A child she may have been but she fucked like an adult. His paws felt around to her hips, held them fast, pulled her back into his augmented thrusts. "You're gonna make this old fart cum too. I'm gonna fill ya right up, you [i]fine[/i] little hussy."

The girl giggled. "I'm a hussy now? Cool."

[i]First girl I fucked who thought being a hussy was cool. Little brat probably doesn't know what it means.[/i]

Rufus hunkered down over Penny, took his tail out of the equation and let his legs do all the lifting again. He was old and tiring out, but he still had the energy to rail a girl half [i](not even - a quarter!)[/i] his age. "Gawd, gonna cum, gonna cum so hard," Rufus panted, rutting her, smashing her like he'd done to so many women before, like he'd fucked the horses and goats of his younger, more outrageous days. A hole was a hole whether it was on a MILF or a mare or a preteen; Rufus was just happy to have someplace hot and nasty to stick his seed.

The girl came with a yowling cry. She shrieked, whimpered, moaned to Rufus that she was cumming, that it felt so fucking amazing and god he was amazing - old or not, he was fucking amazing. Hearing it from a little girl was just fine to Rufus, it buoyed his self-esteem just as much as if one of his peers had cried it while digging her claws into the flesh of his back. He was fucking amazing - that was for goddamn true.

"Yes ma'am, oh yes [i]ma'am,"[/i] grunted Rufus, throwing himself into the spasmodically clenching girl, ramming his wriggling meat into her unbearably snug box. Wetness loped out of her, ran out like someone had punctured a bottle of honey. It rolled down the floor in heavy, slow strands. Its slippery presence made the sex noisy; wet spurts of sound belched into the room as Rufus smacked his hips into her again and again.

Rufus came with the fanfare: "Ooh, god [i]damn!"[/i] He tossed back his head and groaned as he ejected the contents of his nuts into her pert young twat. Thick marsupial seed, fertile and hot for her infertile young muff. Penny moaned for him, cooed for him, told him again how fucking amazing he was. Rufus didn't mind the potty mouth, not when what the girl was speaking gospel.

"Christ, Penny, really?"

Rufus' felt as if a cold hand had gripped his testicles. He hunched over Penny as if to hide her from sight, the baser parts of his brain rushing into an idiot fight-or-flight response at odds with his rational mind which said [i]well I'm fucked now, but maybe if I hold really still...[/i]

A tall, buff brown bear who was obviously related to Penny lifted the bowl off the cake and cut out a slice. Rufus looked at him. He was paralyzed in fear. His erection wilted away to nothing, loins still pointlessly mashed into Penny's rump.

"This old fuck?" asked the big bear.

"Oh, fuck off, Eric," Penny growled.

Eric did fuck off after taking his slice of cake and replacing the bowl. He called over his shoulder, "Figured you could do better than some old pedo."

When Eric was out of sight, Rufus hissed in a needless whisper, "I almost had a heart attack!"

Penny giggled. Cunt dribbling the kangaroo's mess, skirt hanging over her indecency, she lifted off the bowl and dipped her finger into the frosting.

"At least if you would've died, you would've had the best sex ever first."

Rufus backed away from Penny, nearly tripped over his lowered shorts and boxers. He fell back onto the Mardas' sofa and trembled. It was the kind of devastated fear he'd exhibited only once (now twice) in his adult life. When he was nineteen he came within inches of plowing his motorcycle into the side of a UPS van. After he'd brought the bike under control - leaving a snaking stripe of rubber in his wake - he pulled over to the side of the road and sobbed with relief.

Then as now, he trembled like a diabetic on the verge of shock, heart thrumming like a trapped hummingbird, breathing shallow. The coppery flavor of adrenaline stung the back of his throat.

[i]Gawd,[/i] thought Rufus, his mind a jumble and the panic of being busted only just beginning to wear thin. He eyed the little girl, eyed the semen oozing down her thigh and spattering onto the tile as she licked her fingers clean of frosting. [i]Little minx probably ain't lying... I ain't the first fool to put it in her. Not this week. Probably not even today. That girl's a goddamn professional at this.[/i]

She looked back at him and smiled. How could she look so sugary-sweet when she'd just been in the throes of a climax with someone four times her age? Because she was a sociopath. Some kind of vulgar little monster in child form. It was the only explanation that made sense. Rufus remembered being eleven; he was barely even masturbating then, just rubbing himself and marveling at how funny girls made him feel.

Penny cut a slice of cake, brought it over to Rufus and offered it to him with a fork and a smile. When he took it into his quivering paws, she dipped down and kissed his cheek.

"Wanna fuck me again after the pizza gets here?"

Rufus blushed. He busied himself with the cake though the bloody taste of adrenaline left it tasting foul - it was like orange juice after brushing your teeth.

The kangaroo knew he couldn't resist her. He just nodded. He nodded, and he knew that he'd babysit Penny Mardas again. No doubt about that.
