"Ugh... stupid science," Riley muttered, rolling her eyes as she slammed her textbook shut.  Ordinarily, the weasel girl loved science, but all this weather crap was just booooring.  She stood up and stretched, then flopped down on her bed.  "Hmm..."

After a few moments, she stood up.  She needed to take her mind off her homework for a little while, and she knew just the thing to do it.  A grin spread across her face as she ran to her bedroom door, pausing to pick up her school skirt.  She'd shed her school uniform as soon as she'd gotten home, but if she knew her adopted dad, he'd get a kick out of her showing up wearing this!  She quickly pulled the skirt on, then ran down the hall to her parents' bedroom.

"Daaaaddyyyy!" she cried as she ran in.  The weasel girl slid to a halt, pouting as she saw the pink adult was sleeping.  "Oh, Daddy," she whispered, giggling to herself as she tip-toed toward the bed.  "I know how to wake him up..."

Riley climbed up onto the bed.  Her daddy was on his back, sleeping peacefully in the nude.  The cub stifled a giggle as she climbed into his lap, her paws bracing on either side of his chest as she rubbed her pussy against his sheath.  It wasn't long before his shaft slid free of its furry confines, stiffening as she rubbed her sex against it.

The squirrelfox stirred, his paws sliding down and rubbing the cub's legs.  "Mmm... feels like someone's horny," he muttered, his eyes still closed.

The weasel girl grinned and scooted forward, letting her sex slide across her daddy's shaft, coming to rest with his tip at her entrance.  "Don't you wanna see?" she asked.

With a small groan, Beau pushed himself up and opened his eyes.  "Oh my," he muttered, grinning as he slipped his paws up under her skirt.  "Someone knows how to tease daddy," he said, leaning in and giving her a kiss on the lips.

Riley grinned, her paws coming up to rest on her daddy's shoulders as they kissed.  She quickly pulled back from it as she eased her hips back, the weasel girl taking the adult's cock into her slickened sex with practiced ease.  "Mmhmm... I know how much you like it, Daddy," she whispered.

The adult returned her grin and laid back, bringing a thumb to her groin and rubbing against her clit as she started to ride him.  "Mmmmm... that's it, baby... good girl," he whispered.

"Well, well, what have we here?"

Beau chuckled as he looked toward the bedroom door, spying his sister standing there in the nude.  "Our little girl wanted some play time," he said, arching his back and moaning as she brought her hips down, taking him in right to the knot.

Riley giggled and looked at the female over her shoulder.  "Wanna join us, Mommy?" she asked, turning her attention back to her father as she rested her paws on his tummy for support.

Belle grinned and walked over to the closet, and pulled out a skirt of her own.  "Sure... just let me slip into this to tease my little brother..."

The male rolled his eyes, his paws moving back to Riley's hips to help guide the weasel girl as she bounced in his lap.  "Belle, for the last time, we--"

"I know, I know, 'We're twins, we were born on the same day,'" Belle said, cutting her brother off.  "And like I always remind you, I was born seven minutes earlier, so I'll always be the big sister, and I'll never let you forget that, little brother."

Beau sighed and rolled his eyes again, his ears flicking as he heard Riley giggling.  He locked eyes with his cub and gave her his best 'can you believe the shit I have to put up with?' look, which only got her giggling more.  If he didn't love these girls as much as he did...

Of course, Beau didn't have long to be annoyed with his sister.  Once she had her skirt on, she climbed up into the bed and straddled his face, her skirt barely reaching past her hips.  "Why don't you put that tongue of yours to good use?" Belle teased.

"You know me, sis," Beau said.  Without a moment's hesitation, he brought his muzzle up to his sister's sex and began to lick along her slit, giving her groin a tongue bath as he rolled his hips with Riley to thrust into the weasel's snug, velvety hole.

Belle let out a little moan, grinding her hips down into her brother's muzzle as she leaned forward, lying across her brother as though they were going to sixty-nine.  "Mmmmm... that's it," she muttered.  She grinned as she teased up the front of Riley's skirt with her nose, and looked down between the weasel girl's legs.  "Looks fun down here," she said as she leaned in and planted a kiss on Riley's groin, just above the connection between her cub and her brother.

As Belle's tongue took a more active role, Riley grabbed on to her mother's ears.  The weasel girl let out a soft moan as she felt the female squirrelfox's tongue teasing her clit.  Based on the way her tongue was moving, Riley guessed that Belle's tongue was giving Beau's knot a fair working, too, a suspicion confirmed by an extra loud moan from the male, muffled as it was with a mouthful of pussy.  A smile spread across the weasel girl's face as she did her best to angle each movement of her hips toward her mother's tongue.  These little family moments were always the best.

Beneath the two females, Beau was very much enjoying himself.  His paws slipped from Riley's hips as she established a steady rhythm bouncing in his lap, his fingers slipping up his sister's sides then around to her breasts.  Something about Belle's bosom just drew him in.  He grinned into her pussy as he felt her start.  She always jumped when he started to play with her breasts.  It was an expected reaction that nonetheless amused the male to no end, doubly so considering how few other females he'd so willingly fondle. 

"Ngh... Mommy," Riley gasped, tugging on the female squirrelfox's ears.

Belle grinned up at her daughter as she slipped her muzzle out from under her skirt, and pushed herself up, then wrapped her arms around the weasel girl as she pulled her in for a kiss.  Her brother's paws slipped from her bosom as she moved, and trailed down to rest on her hips as she pressed her lips to Riley's muzzle, her tongue slipping into the weasel's mouth as they shared a far more intimate moment than mothers and daughters should.

Riley gasped and giggled into the kiss, her arms wrapping around her mother's shoulders for support as the females kissed.  Her giggles only increased in intensity as the male below her started to buck his hips up, thrusting into her snug passage while the females were preoccupied.  Each upward thrust drove Beau deep into Riley's treasure, his knot teasing at her clit.  It was still definitely too big to fit inside, but that was just fine for both of them.  The feelings were more than pleasurable enough for both of them.

Without warning, Beau threw his head back, letting out a loud moan as he grabbed desperately for Riley's hips.  He pressed his own hips up, burying his shaft in the weasel as it twitched within her, spilling a few squirts of seed into her passage, his knot remaining pressed against her lips but not pushing in.  In a few glorious seconds, his balls emptied into that warm preteen passage, a bit of his seed dribbling out and running down his knot, pooling in his groin.

Above him, the two females broke their kiss, both giggling.  They knew what was up.  Belle looked down at her brother over her shoulder.  "Done already, Beau?" she asked.

"H-hardly," Beau replied, his paws reaching back to give his sister's rump a squeeze.  "Why don't you two switch places and I'll show you how ready I still am?"

The two females exchanged looks, and grinned.  This was going to be a fun evening.
