Zen walked quietly behind his sister Ivi and her friend Limra, also a rat, on their way back from school.  They wore matching black skirts, tails held in a mirrored posture, demure, curled at the ankles to avoid dragging.  They were both freshman, three years above him, and ignored him like usual.  He didn't mind, and it wasn't a long walk home.  Despite knowing Limra for years, she lived a few houses down, Zen had always felt awkward around her, as he did with most people.

Limra's gray blouse somehow didn't show a wrinkle of wear and snugly fit her lean runner's body.  Unlike him and his sister's mottled blend of brown and gray, Limra had perfect snowy white fur.  

"No, more like-"  Limra paused, considering for a moment.  "Fesk."  Her tail twitched.

"Super lanky, weird gray patch on his face?"  Ivi asked.

"Not lanky."  Limra's hips took on a playful sway as she walked.  "Besides, he's a distance runner.  They're all about stamina."

Ivi snorted.  "Like you would know.  Why not ask him?"

"Nah.  Maybe if he came to me first.  I've caught him looking."  Limra all but danced along the sidewalk, her body graceful, every movement perfectly coordinated.  Zen couldn't even imagine having the confidence to walk with so much expression, the dip of her shoulders traveling through her lithe figure and down to the very tip of her tail, flicked to an unheard beat.  "I'm not in any rush.  I like having them look."  Limra turned turned her head, voice musical.  "What about you?"

Ivi blanched.  "Bunch of morons," she grumbled.

"You're not even a little interested?" Limra teased.

"If I could get a dick without the idiot attached to it, maybe."

Limra covered her mouth and laughed.  "So that's how you like it?  Fleeting, no strings attached?"

"More like disembodied.  Just a dick I can keep in the bottom drawer of my dresser."  The tip of Ivi's made a quick slash.

"They make those you know."  The two girls giggled, falling into silence for a time.

Zen pretended not to hear their conversation, though the uncomfortably warm blush in his cheeks wouldn't endure scrutiny.  He kept his eyes on the sidewalk in front of him to avoid staring at Limra's butt, the way her skirt flared out to emphasize her elegant stride.  Knowing his luck, he'd only end up tripping face first into her shapely read.  Not the worst way to die.

Limra leaned in conspiratorially towards Ivi to speak in a hushed whisper that nevertheless carried.  "What about him?"

Zen jerked to attention in time to see Limra tilt her head in his direction.  He stumbled, the burning in his cheeks spreading down into his stomach.  Someone like Limra couldn't possibly be interested in him.

"Ugh, what about him?"

Limra giggled.  "Have to chase away any girls?"

"Hah, as if."  Neither of the girls bothered to acknowledge him.  "He'll go do his homework like a good little rat, then play video games until our parents yell at him.  He has a sister and I still don't think he's ever spoken to a girl."

Limra's laugh was so pretty that it almost distracted him from the caustic heat melting through his gut.  They giggled far longer than was necessary.

"What are you up to tonight?" Limra asked.

"Nothing," Ivi muttered.  "Parents are out.  I'm stuck home."

"I'm going for a run.  You should come!"  Limra smacked the back of Ivi's thigh with her tail.  "Get you something to stare at."

"I get stared at plenty," Ivi grumbled.  "And I told you, parents won't let me out."

"Aww, sounds like you're a good little rat too."  Limra laughed, and only laughed harder when Ivi playfully smacked her on the arm.

Limra parted ways when the three of them reached their street.  Zen didn't take Limra's place beside Ivi, instead following meekly at her heels.  Their parents were already gone for the evening, the house quiet and empty.  Ivi headed into her room without a word, so Zen did the same, lowering his bag to the floor with a sigh and pulling out his homework.

It wasn't much, but he couldn't concentrate, the echoes of Limra's melodic laughter keeping him glancing over his shoulder.  Or he'd drift off, remembering how her skirt danced around her swaying hips, imagining her tail joining in the playful rhythm, lifting the hem of her skirt higher.

During one of these pleasant reveries, Ivi walked into his room.  Zen squeaked and nearly jumped out of his chair in surprise.

"Y-You're supposed to knock," he stammered, covertly huddling in on himself to conceal any indication of where his mind had been.

Ivi raised an eyebrow.  "Guilty of something?"  She had already changed into red and black cloth pants and a worn black band t-shirt, stylized band members clothed almost entirely in spiked bracelets and chokers.  The tip of her tail traced a constant lazy pattern above her ankles like an adder waiting to strike.  Zen envied her, that calm composure, the subtle smile that told him she had a quip ready for anything he might say.  She was the coolest person he knew.  An odd time to think that.

"No!" he said a little too quickly.  "It's just polite," he mumbled.

Ivi rolled her eyes and stalked closer, eyes taking in the open textbook on his desk.  "I wouldn't want anyone walking in on me doing homework at home either.  It would be less sad knowing you were in here jerking off."

Zen blushed but said nothing, tail curling around his ankle and wishing he could simply melt through the floor and out of existence.  What did Ivi want?  Most days she pretended he didn't exist.  They hadn't had a real conversation in weeks.  Ivi stood behind Zen's chair, and he hunched his shoulders, anxiety clawing down his spine as if she might hit him, not that she would.  His neck tensed from the effort of not turning around to look at her.

Ivi spoke in a casual, offhand tone to hide the bite of her words.  "I noticed you checking out Limra pretty hard today."

"What?  I wasn't!"  But the denial sounded feeble even to him.  The fangs sunk in, anxiety transmuted to dread with a single sentence.

Ivi bent forward, placing her hands on his shoulders, her snout right up against his ear.  "Don't worry.  I won't tell.  Though knowing her, she'd probably appreciate it."  One of her hands crept from its perch on his shoulder towards his chest, her voice saccharine.  "Do you like her?"

Zen squirmed in his seat, but Ivi's gentle touch held him straight-backed, heart racing.  "No!  I mean yes!  I mean I don't dislike her, just not like that, I do like her, like she's nice.  And stuff."  He forced his idiot mouth shut.

Ivi chuckled, a low, predatory sound.  "Is that what you were thinking of when you were staring at her ass?  How nice she is?"

Slender furless fingers circled the buttons on his school shirt one at a time, moving lower after each pass.  Ivi's' breath whispered softly in his ear.  A faint hint of her sweet citrus perfume scented the air around her.  She leaned forward slightly to continue down his belly, her small breasts cushioning the back of his head.

Zen panted, his small erection straining against its cloth prison.  His hands gripped the seat of his chair to keep from trembling and his mouth insistently refused to open.  No girl had ever touched him before.  He shouldn't feel pleasure from it.  Ivi was his sister.  He knew he shouldn't find her attractive, but he did, so unbearably attractive, now more than ever.

"You're shaking like a leaf," Ivi cooed in his ear, voice breathy.  "I bet you've never even kissed a girl."  She kissed his cheek, a small breath of mirth tickling his whiskers.  "Never hugged a girl?"  Her fingers reached the final button of Zen's shirt, just below his navel.  "Maybe I'll put in a good word with Limra.  I get the feeling she likes awkward guys."  She grinned.  "And she does have a nice ass, doesn't she?"

The backs of Ivi's fingers brushed the stiff bulge in Zen's pants while reaching for the button.  Zen whined.  He couldn't believe what was happening but desperately hoped it wasn't a dream.  Pleasure raced up his belly at the inadvertent touch.  The button of his pants popped open.  She was really doing it.  This was way to far to take a joke.

"Just keep thinking of her," Ivi whispered.  Her other hand curled forward to gently stroke his throat, forcing his chin up so that he couldn't see what the other was doing.  But he felt it.

Her palm rest atop his erection which leapt at the touch.  Adept fingers took his zipper, teasing it lower, letting him feel each minute clasp release, the pressure trapping his cock easing.  Pleasure danced in Zen's belly with all the passion of Limra's hips.

"I-Iv-"  Zen's throat tightened until he couldn't make a sound beyond muted minuscule squeaks.  Tiny claws scratched his pelvis, fingers slipping beneath the elastic band of his underwear.  An enormous transcendent weight pressed upon his chest, pressure building low in his belly, building until a white mist clouded the edges of his vision.  He couldn't contain something so immense, so inexorable.

Ivi's hand lifted Zen's underwear off his small tapered cock, thumb brushing through the short velvety skin surrounding his base.  But as soon as the cloth not longer trapped his slender pink shaft tight against his belly, he let out a high pitch whine and came before Ivi had the chance to touch him.

Zen's hips bucked, cock twitching freely.  A pleasure unlike anything he'd ever felt drove everything from his body - air, soul, and seed alike.  The final image of Limra's tail rising beneath her skirt mid sashay seared into his mind before the storm overcame him.  Two meager spurts of cloudy semen sprayed across his shirt and pants, his cock continuing to pulse but only dribbling a few drops of clear fluid.

Ivi snatched her hand away before he could get any on her.  She gazed down at him curiously, her fingers never quite reaching their intended goal.  The elastic waistband of Zen's underwear once more trapped his length uncomfortably, his exposed shaft even more sensitive after he'd cum.  Zen whimpered and awkwardly adjusted himself, panting hard, eyes lidded, exhausted.

"At least it's kind of cute I guess," Ivi muttered, searching her hand for any stray trace of Zen.  "But even for a virgin, that was quick."  She sighed and stood up, leaving Zen still half dazed in his chair.  "You owe me."

Zen lazed in the soft afterglow of the experience, mind peacefully blank in blissful silence, arms limp at his side.  It took enormous effort to sit up straight again, his calves aching.  Only then did he realize the open door to his room, his open fly, and the dark stains spreading across his school shirt and trousers.

A whine of dismay and snap of panic let him scramble to shut the door, one hand holding up his pants.  He needed to change anyway, but what did he do about the stains?  He couldn't leave them for his parents to find.  Despite the annoyed grumble he let out, he couldn't find regret anywhere in him.

What Ivi had done-  A warm glow of embarrassment burned in his cheeks.  He didn't even last long enough for her to get his dick out.  But he had been aroused long before Ivi interrupted, and he'd never done anything like that before.  Next time would be different.  There had to be a next time.
