Toddler me on a road trip, strapped tightly into my car seat in the middle of the back seat. My diaper is full to bursting, so much so that chunks of mess are blowing out from the front. I'm giggling and smearing it around my belly and blue stripe on my nose, also popping a few nuggets in my muzzle to snack on while I watch bluey on the headrest screen.

Eventually big burly wolf dad reaches the truck stop and hauls me, car seat and all, out of the pickup and into one of the family rest rooms along with the diaper bag. He puts my seat on the floor while he lays an oversized puppy pad on the foldout changing table. Then he unsnaps me from the seat, grabs me under the arms, and plops me onto the table with a squish. 

He unceremoniously rips my diaper tabs off and hucks my footpaws in the air while sliding the disaster of a diaper out from under me. He then flips it over and plops the messiest part of the seat right onto my muzzle to let me have a delicious chunky meal, giving it a squeeze around my muzzle and perky ears.

Munching away happily, I feel my footpaws hucked up again and my butt dragged right to the edge of the changing table; the mucky mat sticking to my blowout-messy back. I hear a zip and some rusting, then feel the tip of Dad's enormous cock pressing against my already sloppy tailhole as I continue chomping.

With little ceremony, I feel his paws grip my shoulders and jam me down onto his massively burly cock, quickly jackhammering into my butt over and over with reckless abandon as he growls deeply. I can feel the huge shaft forcibly shoving aside my insides as my belly swells several inches with each thrust. My tiny peepee strains against the itty-bitty cage it's locked into; the integrated cath tickling my bladder and prostate with every slam as I gleefully swallow down a particularly big log. 

It doesn't take long before I feel Papa's knot stretching my hole even wider, his growls getting deeper and his thrusts even more fervent. Suddenly his melon-sized knot pops inside me and I feel his belly fur squelch against my filthy butt. He howls loudly as my whole body bounces up and down on the table, my belly swelling like a balloon from the combination of the extra length, huge knot, and the overwhelming amount of cum filling my insides to bursting.

I feel a burp and a sniffle hit me, a bit of his cum dribbling from my nose again, the same way it always does when daddy pounds me silly. My little cage is dribbling too, but it can't be seen through all the muck coating my lower half. I can also smell a little bit of sweet acrid twinge of skunk spray from my barely functional anal glands; a vestige of my great grandfather's lineage, no doubt  triggered by my dad's massive knot popping into me.

Papa prefers these truck stops on long road trips because of the shower stalls right inside the family restrooms. After he picks himself up off me and the changing table, he simply leans back and I lift completely off the table; still solidly locked on his knot. He turns around and peels the mat and husk of a diaper off of me, grabbing a half-roll of quarters from the front pocket of the bag on the counter. He then bounce-marches his cock and me over to the shower and begins popping in quarters to rinse us off.

About halfway though the shower I finally slide off his knot with a gush, and after being set down on the gooey tile floor, I start scrubbing the bubbles into my fur to at least temporarily get the brown out.

After a lot of cleanup, fresh padding on both Dad and I, and an extensive wiping down of the car seat, I'm being hauled back out to the pickup; most of my stink now gone from him leaving the windows partially open. As he winks back to the lusty-eyed attendant and straps me in again, we pull away and get back on the road. 

My diaper already squelching in the back from all the leaking cum, ten minutes later I see Dad catch my eye in the mirror, then he grins and grunts, the cabin immediately filling with a different, more earthy deep stink than my own. He winks at me and I whine in excitement as he says in a low rasp, "dinner will be all ready for you when we get home, kiddo."
