"Haha, don't mention it dad." You chuckle, continuing to knead his fat rolls, before moving downwards, your chubby paws caressing his enormous thighs, and eventually his own big feet, digging your thumbs into his soles, which provokes a moan from the old lion. "Thanks boy, my paws were--URRRRP--achin' from the walk here." You bury your nose in one of your father's large, dirty, furry feet and take a deep sniff. "Mmmph, smells like it dad." The stench would cause a lesser man to faint, but to you it's a smell you now find oh so familiar. As you continue to rub his big feet, you can't help but bury your muzzle into them, dragging your tongue along his sole and slobbering on his toes, making him weakly chuckle as he scratches his hefty belly. "Fuck that's good, son."
As he shakes his gut, you can see his fat belly rise, fupa visible between his legs, and your hunger increases. Raising up his meaty thighs once more, you bury your face in your father's sweaty, musky fat pad as he farts. "Ugh, you're so sweet to me." You dad praises as you start to root around inside, tongue coaxing out his fat-buried dick and sucking on it. You can taste his sweat and smegma, it's such a deliciously potent thing, something irresistible that reminds you of how your father was once king of your pride.
You dad's heavy chest rises and falls as he moans in ecstasy, passing more foul-smelling gas that does nothing to deter you. If anything it makes your own cock harder, rutting against your own fat folds as you grab the old lion's hips, sucking more aggressively, the weight of his enormous gut covering your mane. He groans, panting as you service him, gently petting your arms as your pace quickens, your freehand reaching below your own stomach to paw at your pre-leaking dick, the craving overwhelming.
"Fuck, fuck--!!!" He groans in bliss, "I'm--I'm cumming!" He snarls and thrusts into you, and you can feel his cock start shooting off. Slimy, salty jizz fills your leonine mouth, a delightful taste. You go cross-eyed in sheer pleasure yourself, orgasming too. Suddenly another flavor and texture fills your mouth, the more fluidic taste of piss is pouring from your father's cockhead. "Fuck, s-sorry..." He moans, his grin suggesting he wasn't at all, "I-I couldn't hold it..." You gulp it down, your dick still twitching as it cums, jizz and urine dribbling down your multiple chins and your father's fat pad.
Once the stream dies down, you remove your face, splattered in your dad's sticky fluids, and look up at the former king, who smiles down on you proudly, "That's my boy." He chuckles, petting you, as you confidently swallow, before licking your own jizz off your fingers. It all tasted so wonderful, it didn't even phase you that a normal human might find this slovenly behavior disgusting. This was just totally normal behavior for you now.
