Becky giggled and reached out to pat his arm.   "It's ok, Chuck."   She looked up at the clock, then turned to Robbie and leaned in close, and whispered in his ear, "Hey, Robs... while Martin's busy with your dad, think you might wanna play with me for a bit?"

Robbie squeaked at the suggestion, and looked from Chuck to Becky.   "We can't do it here!" he whispered back.   "And I don't wanna leave Chuck alone."

"He's not alone, he's got your sister," Becky whispered.

The fox shrugged.   "I guess," he whispered, then looked over at Chuck.   "Hey, Chuck.   Uh... mind if Becky and I sneak off to my room for a bit?"

Chuck's ears perked up as he looked at the fox.   "I-I guess... w-w-whatcha gonna do?"

"Yiff," Becky said, winking at the border collie.

The pup's cheeks flushed at the word.   "Oh... o-ok..."

"Aww!   No fair!" Ellie said.   "You guys get to yiff, and Martin's prolly yiffing daddy, and I'm left alone!"

"You won't be alone, Chuck will be with you!" Becky said.

"But I can't yiff HIM!" Ellie protested, not noticing as the pup tried to sink deeper into the chair, his face becoming a deeper red.   "He doesn't like yiffing!"

Robbie sighed.   "Tell you what.   I'll yiff you tonight after my friends go home.   Deal?"

"Deal!" Ellie said, giggling in triumph.

Becky grinned and grabbed Robbie's paw, dragging him at full speed out of the den, leaving Chuck and Ellie alone.

They were barely half-way up the stairs before Becky started groping Robbie.

"You really can't wait, can you?" Robbie whispered as they made their way to his bedroom.

Becky giggled and batted her eyes at the fox.   "Can you blame me?"

The fox shrugged, and gasped as Becky pulled him in for a kiss.   His back collided with his bedroom door, and his arms flew instinctively around the rabbit, holding her close as her tongue sought entrance into his muzzle.

Locked at the lips, the fox relied on his knowledge of his room's geography to guide them over to the bed.   When he got there, he broke the kiss, and sat down on his bed, pushing himself back a bit as Becky grinned at him.

"So, uh... whatcha wanna do?" Robbie asked.

"Oh, I figured I'd start like this," Becky said, starting to lift up her shirt.

Robbie watched as the rabbit pulled her shirt up slowly, revealing greater and greater portions of her back.   As she got it to her armpits, he noted the straps of her bra.

"Didn't know you wore those," Robbie said.

Becky grinned and took a step back.   "Well, why don't you see if you can get it off me?"

"I can try," Robbie said, letting out a little squeak as Becky sat down on his knee.   He reached up, looking at the band, and slipped his fingers up under the band.

"Oh, you silly boy," Becky said, giggling a bit.   "There are straps back there you need to undo."

"Oh!" Robbie said, blushing as he withdrew his fingers.   He leaned in a little closer, and spied the little hooks and eyes against the black fabric.   "Sorry, they're a little, uh... hard to spot."   A few fumbling seconds later, and the bra was loose.

"Good boy," Becky said as she stood up, holding the bra against her budding breasts as the straps fell loosely to her sides.   "Guess you earned this," she said as she turned around, and slowly pulled her bra down, revealing her full chest to the fox.

Robbie chuckled as she pulled off her bra, and grabbed at his own chest.   "Think yurs are almost as big as mine!"

Becky giggled and threw her bra at the fox's head.   "Weirdo!" she said, turning around and shaking her rear at him.

The fox chuckled and grabbed Becky's cotton tail, giving it a little squeeze.   "Cute tail, though!"

The rabbit squeaked and jumped at the feel of the fox's paw on her tail.   "I guess... yours is much nicer, though.   So floofy!"   She turned around and pounced the fox, reaching behind him to grab his own tail.

Robbie giggled a bit, swishing his tail about as the rabbit tried to grab it.   The game only lasted a few seconds, though, before Becky pressed her lips to Robbie's, her paws slipping up under his shirt.

"No, mine are bigger," Becky whispered as she groped Robbie's chest.

The fox blushed and licked Becky's nose, and raised his arms as the rabbit pulled his shirt off.

"Much better," Becky whispered as she tossed Robbie's shirt aside   "Now, where were we?"   She straightened up and took a step back, then turned around again, bending over and displaying her rear to the fox.

Slowly, she began to pull her skirt down, revealing her forest green panties to the fox for the second time that day.

"You're really enjoying this, aren't you?" Robbie said.

Becky grinned as she got her skirt to her ankles, and turned to face the fox, kicking off the garment as she did.   "Why don't you tell me?" she said as she grabbed his paw and slipped it down into her panties.

Robbie gasped as the rabbit put his paw against her crotch.   He could feel how moist she had gotten already, and couldn't help but to dive his fingers in.   For a few moment, Becky allowed this, before she stepped back and pulled her panties down.

"Now to get you undressed," she whispered as she knelt down in front of the fox.

Robbie watched as Becky unbuttoned and unzipped his shorts, and started to pull them down.   "There's no way I'm your first," he said.

Becky giggled and stuck her tongue out at the fox as she pulled his shorts down.   "Robs... I have an older sister and an older brother.   They sometimes brought boyfriends and girlfriends home.   Thin walls, and I share a bedroom with my sister.   I picked up a few things," she said with a wink.   "The internet's pretty neat, too."

Robbie's eyes widened at that last one.   "You look at porn on the internet?"

The rabbit grinned as she stood up, and pressed a finger to the fox's muzzle.   "My little secret," she whispered as she groped Robbie through his briefs.   "Mmmm... someone's got a stiffy..."

Robbie blushed a bit, wiggling his hips as Becky fondled his erection through his undies.   "Well, what did you expect?"

Becky just giggled and started to pull the fox's underwear down, watching as his cock sprang to attention as she freed it from its cotton prison.   "Just glad I can turn you on," she said, wrapping a paw around Robbie's shaft.

The fox murred softly as the rabbit started to stroke him.   "I guess," he said, reaching down and rubbing Becky's shoulders.

The rabbit grinned up at him, then looked down at his cock.   "Yours is so different from my brothers'," she whispered.

Robbie shrugged.   "Never seen a rabbit penis, so I dunno," he said.

Becky giggled.   "Come to my house sometime.   Chances are one of my brothers will run around naked before you leave."   She looked at the fox's penis for a little longer, then leaned in and licked the tip.

Robbie gasped as he felt the rabbit start to lick his shaft.   He watched her for a few seconds, then patted the back of her head.   "It, uh... feels nicer if you put it all the way in your mouth," he said.

Becky nodded, and moved her muzzle down, taking the first inch of the fox's cock into her maw.   She flicked her tongue along the underside of his shaft as she lowered her muzzle a little, taking in another, her teeth just touching his shaft.

"C-careful of your teeth," Robbie hissed, shutting his eyes and trying to relax as the rabbit took him deeper into his muzzle.   He knew it'd be a tall order with her species' rather prominent buck teeth, and hoped that she could work around them.

It took her a few seconds, but the rabbit managed to get her teeth out of the way, and pushed her muzzle down further, taking in more of the fox's length.   She had to admit, she wasn't quite prepared for the reality of having a penis in her mouth, regardless of what her sister had told her, or what she had gathered from her reading on the net.   It wasn't unpleasant, at least.   Unique was probably the best way to describe it.

Above her, Robbie relaxed as Becky worked her muzzle along his shaft.   For some reason, her buck teeth scared him more than Martin's sharper ones.   At the very least, it was clear that this, at least, was something completely new to her.   "Try sucking it a bit," Robbie said, rubbing her ears.

Becky flicked her tail a bit as she started to suck on the fox's length, her tongue starting to work around it.   The feel of his warm flesh in her muzzle was starting to grow on her -- until a burst of pre hit the top of her mouth.

Almost immediately, the rabbit recoiled, caught completely off-guard by the sudden squirt in her mouth.   "What was THAT?!" she asked, rolling her tongue around her mouth and spitting into her paws.

"S-sorry," Robbie said.   "Sometimes I, uh... squirt a little bit before I cum..."

Becky nodded, grabbing a tissue from the box on the table to spit into.   "Ugh... if that's what your cum tastes like, I dunno if I'd want THAT in my mouth."

"It's not that bad," Robbie muttered, but shrugged.

Becky stood up, then sat down on the bed next to Robbie.   "So, uh... wanna try me now?"

Robbie shrugged, and pushed himself up onto the bed as Becky climbed up fully, spreading her legs and laying her head on one of the fox's pillows.   A few moments later, the fox found himself kneeling between the rabbit's legs, leaning in to get his first good look at a girl's privates.   "Umm... what do I do?"

Becky giggled and spread her lips a bit, presenting herself to the fox.   "Well, you can start by licking inside... and you could try to lick my clit, too."

"Your what?" Robbie asked.

Becky giggled again, blushing a bit.   "Don't you know a girl's parts?"

"N-not really," Robbie admitted, blushing himself.   "I mean, my mom's told me about them, but I don't really know where any of them are..."

Becky rolled her eyes, then flicked a finger across the nub of her clit.   "This here's my clit.   It feels really nice when you rub that.   That's what you gotta know for now.   And, uh... I guess we girls get wet... I didn't like your, uh... stuff, so if you don't like mine, it's ok."

Robbie nodded, and leaned in close, inhaling the rabbit's scent.   Slowly, he leaned in closer, and gave a quick, tentative lick to her inner lips, getting a taste of her juices.   The flavor was hard to describe, though it wasn't unpleasant.   He licked again, taking longer this time, to really get a taste for the girl, his ears flicking as he heard her moan softly.

The fox kept this up for a few more seconds, getting a good taste of the girl, before moving up, flicking his tongue against the little nub at the top of Becky's vagina.   This garnered a much stronger reaction, the rabbit's body involuntarily shivering as she moaned.   A grin spread across the fox's muzzle as he repeated this action, his paws resting on the girl's hips as he teased her.

"N-not so much," Becky gasped, pushing the fox's head down a bit.   "That's too much," she panted, shivering a bit at the overstimulation.

Robbie nodded and went to work again, slower this time, swirling his tongue around as well as over the little nub, getting a feel for the rabbit's privates.   Much as he hated to admit it to himself, he was starting to really like playing with pussy.

Another minute passed before Becky interrupted the fox again, pulling his muzzle back.   "Robbie... I need you inside me," she whispered.

The fox chuckled a bit and nodded, crawling up on top of her and lining up his nearly-forgotten erection with Becky's moist entrance.   "Let's do this," he whispered, smiling down at the rabbit as he grabbed the base of his cock, guiding it into her entrance.

Both cubs gasped as the fox sank into the rabbit.   As he hilted inside her, Robbie wrapped both his paws around the rabbit, hugging tight and nuzzling her cheek.

"Oh, Robbie," Becky whispered.   "You feel so good inside me."

Robbie moaned softly and kissed her cheek, and whispered back, "You feel really nice."

A moment passed as the two cubs merely revelled in the warm feelings emanating from their groins.   Until nature took over, and the fox's hips began moving of their own accord, the boy working into a slow, gentle rhythm thrusting into the rabbit girl beneath him.

Becky moaned softly as Robbie began humping her, and she wrapped her legs around his as best she could, her paws roaming over his back as she held him close.   "Fast as you can," she whispered.

Robbie squeezed his eyes shut and nodded, starting to pant as he worked up his pace, eager to please the rabbit beneath him.   Soon, both cubs were panting as Robbie thrusted hard and faster into the girl, a thin sheen of sweat working over their bodies as the boy's balls slapped against the rabbit's nethers.

It wasn't long before Robbie felt his climax approaching.  Something about Becky had that effect on him.  Whether it was how long they'd known each other, or maybe that the fox really did have feelings for her, he couldn't be sure.  What was absolutely certain, though, was that she felt awesome inside.

A gasp escaped the fox's muzzle as he felt the rabbit's paws grab his butt.  He flexed his cheeks in her paws, thrusting a little faster into her as he felt her slip a finger down to touch his tailhole.

"Mmmm... you like it when I touch you here?" Becky whispered.

Robbie could only nod, words failing him as he felt the rabbit's digit starting to press inward.  The development was unexpected, but not something the fox could object to.

Both cubs gasped when Robbie's knot popped into Becky's pussy.  Neither cub had noticed it until Robbie tried to pull back and found himself stuck inside.  Becky grinned at the fox, and used his now immobile state to press down hard against his tailhole, her finger pushing into the fox's rear with relative ease.

As Becky's finger pressed into Robbie's prostate, the fox lost it.  He moaned out, trembling atop the rabbit as his cock twitched, filling her with his seed.

The fox's orgasm pushed Becky over the edge, the rabbit moaning herself as she hugged Robbie tight, holding onto him for dear life as her orgasm rushed through her body.

For a few long, blissful moments, the two cubs shook as their climaxes overwhelmed them.  All too soon they returned to earth, Robbie rolling onto his side and pulling Becky along with him, the rabbit's finger still buried in his tailhole.

"H-how... did you know... about that?" Robbie whispered as he felt Becky's finger withdraw from his rear.

Becky giggled softly and licked the fox's nose.  "Porn... read that... guys have a spot in there... that makes 'em feel good... guess I found it, huh?"

Robbie could only nod, and gave Becky another little squeeze as he licked her muzzle, earning another round of giggles from her.

For a few minutes, the two lay together, eyes shut, arms and legs tangled, crotches linked by the fox's knot.  After the exertion of their mating, cuddling in the afterglow was a welcome reprieve, almost more fulfilling to the two cubs then the act that had preceded it.  Soft gasps escaped their muzzles as, with a soft pop, Robbie's knot slipped from the rabbit's pussy.

As soon as he was free, Robbie got up, and gently pushed Becky onto her back as he climbed in between her legs.

"Robbie, what are yo-OH!"  Becky's question was cut off as she felt the fox's tongue against her slit.  She grabbed his head and pressed him down into her crotch, his nose grinding against her clit as his tongue worked deep into her folds, finding his seed within her.

The fox kept this up for a minute, then pulled his head back, grinning at the rabbit.  "I think you taste better mixed with me," he whispered.

Becky giggled and grabbed a pillow, tossing it at the fox.  "Robbie!  Eeeeww!"

Robbie laughed as the pillow hit him square on the muzzle.  "Hey!  You don't know what I taste like!" he said.

The rabbit grinned and dipped a couple of fingers into her cunny, then withdrew them, taking them right to her muzzle.  "I think I got a bit," she said, and stuck them in her muzzle, suckling the juices from them.  Her face screwed up a bit as she pulled them out.  "Huh... I'll have to try it fresh... don't really like it mixed with mine."

The fox shrugged as he put his pillow back on his bed, and laid back down next to Becky.  "Umm... have you tried yours before?  Ya know, your, uh..."  He reached down and ran his finger around the rabbit's pussy.

Becky nodded.  "Yeah, I've tried it a couple times.  It's alright, I guess," she said, giving a little shrug.  She giggled a bit as she looked at Robbie.  "Your fur's all matted around your muzzle."

"Totally your fault," Robbie said, sticking his tongue out at her.  "For being so wet!"

Becky giggled and grabbed the pillow she was using, and bopped Robbie over the head with it.  "Oh, you!  Let's go clean up and get back downstairs."

Robbie chuckled and nodded, slipping out of bed.  "Sounds good.  Hope Chuck wasn't too bored without us!"

The two quickly pulled their clothes back on, Robbie making a pitstop in the bathroom to wipe down his muzzle, and the two cubs went back downstairs, paw in paw.

As they passed the kitchen, Robbie poked his head in.  His mother was at the stove with a pan laid out.  "Whatcha makin', mom?"

Terry smiled at the two cubs.  "I figured I'd make a lasagna for dinner tonight.  Cheese ok for you, Becky?"

Becky giggled and grinned.  "That sounds great!" she said.

"Excellent!" Terry said.  "I'll have a meat sauce on the side for the carnivores, and I'll leave it out of the lasagna for you."

"Neat!  Thanks, Mrs. Langley!" Becky said.

"It's no trouble at all," she said.  "It won't be ready for a while yet, so you two may as well go play some games."

"Oh, we will!" Robbie said, grabbing Becky's paw and leading her back to the den.

When they arrived, they found Ellie and Chuck still sitting together on the recliner, watching a cartoon.  They seemed to be sitting a little closer together.

"Hey, Chuck, Ellie," Robbie said as he sat down.  "Didja miss us?"

Ellie giggled and stuck her tongue out at her brother.  "Nuh uh!  Chuck's awesome!"

"You two been watching cartoons this whole time?" Becky asked as she sat down next to Robbie, pulling him in close to her.

The two smaller cubs exchanged glances, then looked at the rabbit and fox.  "Yup!" Ellie said, giggling a bit as she felt Chuck sink into the chair a bit.

Robbie shrugged and grabbed his controller.  "Wanna play another game now that we're back?"

Ellie grinned and grabbed her controller back up.  "You know it!"

Becky grabbed a controller for herself and handed Chuck the last one as Robbie set up a game.  Soon, they were all laughing as they got into their racing game.  As they finished the first lap, Martin returned.

"Took yur spot," Becky said as the wolf came in.  "Hope you don't mind."

"No biggie," Martin said as he flopped down on the couch.  "Hey, Ellie, Robbie?"

Robbie paused their game, and the two foxes looked at the wolf.  "Yeah, Martin?" Robbie said.

Martin grinned at the two foxes.  "I fucked your dad!"

Ellie giggled wildly at that, then leapt up and ran from the room.  "DADDY!!!  Me next me next!" she cried as she ran upstairs.

Robbie groaned and rolled his eyes.  "My family is so weird..."

"But awesome!" Becky added.

Martin grinned and grabbed her controller, then flopped down on the couch next to Robbie.  "Well, if she's not gonna finish this race, guess I'll have to wipe the floor with you guys.  Let's do it!"

*	*	*	*	*	*	*	*	*	*	*	*	

A few hours later, Becky, Martin, and Chuck went home.  Robbie saw his friends off, then went back to the den where his sister was waiting for him.

"Hey, big bro," Ellie said, grinning at her brother.

"So, I guess I owe you something, huh?" Robbie said, letting out a little sigh as he flopped down on the couch.

Ellie giggled.  "I guess.  But not right now.  Let's just watch some TV."

Robbie raised an eyebrow, then shrugged and settled down on the couch.  As he picked up the remote and started channel surfing, Ellie got up from the recliner and sat down next to Robbie, snuggling up to him.  The fox shrugged and put an arm around his sister, holding her close as he flipped through stations.  "How's this one?" he asked as he stopped on a sitcom.

"That'll do," Ellie said as she laid her head against her brother's chest.

Robbie nodded and put the remote aside, settling into the couch with his sister.  "What a day, huh sis?"

Ellie didn't reply.  When the fox looked down, he saw that his sister had fallen asleep.

"Figures," Robbie whispered, and glanced at the door, then gave Ellie a quick kiss on her forehead.  "Ah, well."  As he lost himself in the tv show, a smile crept across his muzzle as a thought ran unbidden through his mind: 'girls.  I'll never understand 'em.'
