Helping Tongue

Giving a small groan as she held up a hand in front of her squinting eyes, trying to block out the rays of sunshine flooding her bedroom, Kaysee flopped her head back onto her pillow, the Australian shepherd's blanket rolling off to the side to reveal her nude form. The woman preferred to sleep without any clothes, especially during the warm summer seasons, her puffy spade peeking out from between her thighs as she yawned and stretched. Glancing down to her side, the canine found her son still asleep, clinging to her side as he snored, equally as bare as his mother, his little sheath just barely poking through his thick crotch fur. Kaysee smirked softly as she poked her muzzle down next to the five year old boy's ear, whispering quietly while gently caressing his cheek, 
"Max… Maxie… time to wake up~" 
The young pup began to stir from his slumber, moaning as he buried his face against his mother's belly fluff, hugging her side. As much as Kaysee would've loved to watch the adorable cub all day long, a loud and audible grumble from her gut forced the Australian shepherd to hurry her son along slightly, gingerly prying his hands off of her so that she could get off of the bed, 
"Sorry honey, but cuddling is gonna have to wait a little bit, mommy really needs to go." 
The woman only meant it figuratively however, as she had absolutely no intention of going any further than a few steps away, rolling off of the bed and quickly stepping over to her cabinet, a slight grimace on her face as she felt her belly giving a needy pinch. Kaysee grabbed a towel from the cabinet, laying it down onto the bed before climbing back up, huffing gently as she squatted over the covering while Max turned to watch her with a smile, crawling closer to get a better angle. The dog didn't usually bother with the toilet when taking care of her business in the mornings, since she found her way to be quite a bit more enjoyable, and her son certainly didn't mind the show either. Shuffling right in front of his mother, pushing one of her knees out of the way slightly as she leaned back and lifted up her tail, Max watched with a captivated expression as she moaned and bit her bottom lip, laying her other hand down on her puffy spade as she relaxed. 

Sighing and thrusting her hips forwards, Kaysee gently rubbed the peak of her plump mound with her thumb, glancing her clit with the finger as she let out a tiny gasp, feeling her tailhole flexing open and closed in rhythm with her massage. She began to push, holding her breath and grunting as she began to feel the mass in her gut moving slightly, but not quite enough to reach the relief she'd been hoping for, staying in her with a tantalising sensation. Taking a break to breathe, the woman kept pushing and huffing, shifting around as she tried to find a good squatting position, unable to quite get her body properly relaxed for the unloading. Max noticed his mother's conundrum, getting a bright idea on how to help her, having gotten very adept at getting her relaxed, 
"I'll help you~!" 
The little Aussie plopped down onto his back before scooching underneath his squatting mom, grabbing onto her thighs as he settled into a comfy position, his nose almost pressed against her pucker while his maw hovered right over the woman's spade. Smirking at her son's good idea, as well as his eagerness, Kaysee hunched down over the cub's face, gently pressing her swollen pussy lips against his snout as she pet the boy, giving his sheath a few teasing fondles and gropes as she huffed at the feel of his breath against her wet mound, 
"Oh, you're so sweet, helping your mommy like this~" 

Getting into position underneath his mother, Max licked his lips before nuzzling his maw right up against her open, tracing her pillowy soft spade for a moment, following the contours of her pussy lips as she gasped softly, her legs tensing as she nearly lost her balance on the bed, having to lean on his chest with one hand as she moaned, 
"R… remember what I taught you a few weeks back?" 
"Mhm!" 
With his mouth preoccupied, the cub nodded and moved his tongue to the apex of his mom's mound, thinking back to the lessons she'd given him on how to properly eat out a lady. Sticking his tongue out, he lashed the tip of his agile tongue at her clit, massaging and rubbing it as Kaysee quivered from head to toe, panting heartily as her tail wagged, giving the boy some pets on his belly as she encouraged him further, 
"Oh, good boy, that's it! Just keep going, just like I taught you~!" 
The pup's eager lapping had a near immediate effect on Kaysee's body, a small blush appearing on her cheeks as she felt her tailhole relaxing, her bowels working to squeeze out the load waiting inside. Trying to steady her breathing, the Australian shepherd began to push once more, feeling the thick log inching closer and closer to her tailhole with every strained push, grunts mixing in with her moans as her son's tongue enveloped her clit, dancing between the hard nub and her inner folds. 

Pulling his mother down against his muzzle, Max watched as the Aussie's tailhole winked at him, flexing slightly wider with every push as she strained. The boy's tongue was deep in Kaysee's cunt as the very tip of the firm log began to poke out of her asshole, slowly growing out as she held her breath and grunted, gently rocking back and forth to rub her spade on her son's mouth as she moaned,
"D… don't stop~!" 
The boy had absolutely no intentions of stopping, digging deeper into his mom's dripping wet folds as he reached a hand up to her flank, grasping one of her ass cheeks and pulling them apart, wanting to get a better view of the show while also helping her out. Pushing harder and harder, having to occasionally stop to catch her breath in between, Kaysee gasped in bliss as the first nugget finally squeezed out of her donut, spreading her hole open before landing onto the towel with a thud, followed soon after by a second, slightly larger, chunk. Max intensified his lapping as soon as he saw the floodgates starting to open, almost shoving his entire muzzle into his mother's spade as he licked and kneaded at her clit with his fingers, getting her to writhe around on top of him as she reached her climax. Howling out loud in bliss, Kaysee's tailhole opened up to let out the largest log she'd had stuffed inside of her, shivering as it passed through her pucker, long enough to need two pushes to fully get it out. The thick log dangled from between her cheeks for a moment before splattering onto the towel, a handful of slightly smaller and softer pieces curling around it as she moaned, showering her son's face with her sweet sap. With her orgasm, and her dump, done, the panting canine looked down to see the impressively large pile of shit steaming on the towel, and the smiling Max laying next to it, cleaning his snout of her juices as she huffed with a deeply satisfied smirk, laying down next to him and giving the cub a kiss.
