A Lucario with a bit of a cocklust problem.

It was only meant to be a one time thing. Something to help with my growth into becoming my Master's greatest pokemon, but it became too much for me. He can never know that I failed him…

"Hah… hah… hah… M-Master… Mmm… Harder…" I pant lustfully on the bed. I am laying on my side with my left leg held up by my Master, his big meaty cock thrusting in and out of my needy hole.

It was mid spring and mating season was in full swing. It was my first season and it was awful. My whole body felt like it was on fire and any touch made my spine shiver. Master knew just from looking at me that I was suffering.

And he took pity on me.

I whine as he hilts me as deep as he could, his entire cock making my insides bulge. I never felt so full and so good in my life, I need to have more. "Master! Fuck me!" I cry out, squeezing down on his cock when he tries to pull it out.

I whimper when he fully pulls out, his warm cock resting on my taint and lightly pushing against the back of my sack. "P-Put it back in… Please…"

"Lucario." He says, turning my snout to face him. I couldn't help but blush when I saw him from behind me. I never noticed just how handsome he is until now.

"This is only going to be a one time thing..." He says, petting my head before carefully realigning his shaft to my achy tailhole. "No one can know about this…" He grips my own knotty cock, the red meat already dripping my cum from all the wonderful orgasms he brought me.

"Alright?"

My mind is clouded with lust, but I simply nod my head. My tongue lolls out of my maw as his cock pushes back inside me, I bring a paw back to grab onto his head and pull it towards mine. It sent fireworks off in my head when I locked lips with that handsome man and he begins to unload his human seed in me.

It was greatest feeling ever to be filled with his cum, watching my tummy swell with his liquid love. I don't ever want this to end…

It's been years since he helped me with my problem, but he made it worse in the end.

Master is asleep on his couch, taking a quick nap from his long hours at work. His sleeping form musky with the smell of his sweat just makes him all the more attractive. I crawl up to the front of the couch and undress his lower regions, fishing for that succulent dick hiding in his layers of cloth.

Pulling that thick meat out, I can't help but drool at the throbbing mass. I nuzzle and lick at the length, still smelling my scent on him from last night… and the night before that… and the night before that.

I have to bring a paw to my own cock and grip my fat knot, squeezing it in sync with my kisses and suckles on Master's tip.

I moan, bringing my mouth further down upon his meat, swallowing it all into my throat. It hurts a little feeling my neck bulge like this, but it's so worth it to get master's essence.

A squeeze on my knot and a suck on his cock, it repeats like clockwork as I please his body to help douse that burning fire of lust that was never extinguished all those years ago.

Master groans to my left, his cock throbbing in my throat as his tip swells up. I clench my eyes shut as I let him pump my stomach with his cum, keeping myself latched onto him to get every single drop of that sweet cum.

My tummy feels so full, but it's so worth it. I squeeze my knot one last time before pulling off Master's cock, watching the saliva slick shaft droop and slowly shrink to its flaccid size. I wipe my maw of any drool and put his dick back into its cloth prison, kissing it one more time before sealing it inside.

Master is none the wiser as he stretches his leg before turning onto his side. I chuckle at his cute shuffles before leaving him to rest for the coming night…

"Come on Lucario, it's time for bed!" Master yells for me from his bedroom.

"I'll be there! Give me a sec." I tell him, swirling a paw digit in my ass to help spread the lube around. I bite my lower lip as I force myself to not get aroused from this. I pull my paw out with a wet Shlick, my ass gaping a little before closing up slowly.

I let out a sigh and a shiver, my body is finally ready for tonight. "I'm coming Master~" I say in a lewd tone, walking in a skip like fashion to the bedroom.

I open the bedroom door and see Master in his bed, a blanket left open for me to slide into, and eventually for Master to slide into me.

I climb onto the bed, crawling inside the blanket and snuggling up him. He holds me close to him and scratches behind my ears, relaxing his grip and slowly falling asleep.

Now I wait, gently caressing his inner thigh and slowly snaking my paw to his boxers. Master snores beside me, completely oblivious to his single cover of modesty being pulled down his legs.

I lick my lips in anticipation as I feel for his thick meat, gripping it in my paw and stroking it to life. Every pulse it makes, it grows bigger in length and girth. Soon, it's at full mast and it looks beautiful. I kick the blanket off to give me some space to please my Master. I straddle his lap and continue to stroke his fat length, letting my own smaller cock rest against his.

"Such a big cock…" I say, lifting myself up and over his length. "Let's get you inside…"

I bite my lower lip as I press his thick head against my loose pucker, the lube inside and outside helping me get that beast inside me. "Hmm… Get in me…" I moan, feeling the head finally slip in.

Inch after inch, it stretches my innards to make room for itself. My normally taut abs has a lovely phallic lump bulging out and traveling up as more of his meat enters me.

I have to stop once I get to the hilt, shuddering and panting from the near orgasm. "Master… Hah… Such a big boy…"

I bring a shaky paw to his chest, holding myself up so I don't risk waking him up. I whine as his cock pulses against my prostate.

"F-f-fuck…" I whine, my legs twitching as my red rocket spills pre onto master like a hose that isn't shut all the way.

I trace small circles on Master's chest as my body's insides loosens up, enjoying smoothness of his skin instead of the usual furry mess of other Pokémon. "Quite the h-hunk you are… A-and you're all mine…" I say as I caress the formed bulge in my abdomin.

I lean backwards and grab hold of Master's shins, levering myself in a better and more flexible position. Thrusting upwards, my cock flops onto my stomach as Master's length slips out to the thick tip. My tongue lolls out of my mouth as I hilt him back inside, my cock slapping his stomach and his dick bulging out of my tummy.

"So… sexy…" I say to myself, grinding his lap and rotating the lump around with my ass. I grin, this feeling never getting old as I piston myself on his lap.

Master stirs under me in his sleep, his arms stretching and legs kicking to keep the blood flow going. I sit still as he does this, not wanting to risk him waking up and finding himself balls deep in me. I watch him shift and shuffle before he finally settles down; his body going lax under me and back to drooling on his pillow.

I caress his chest and lean down to lick his neck. "Good boy…" I say, right before bouncing my rear on his cock again.

I moan when the pleasure comes back tenfold and ravage my innards, making me whine and squeal in delight from the prostate poking.

I shudder when my cock begins to dribble cum on Master's stomach, leaving a sticky mess of my orgasm. "Mmm, first one of the night. Let's see how much more you can milk from me Master." I moan, leaning down on him and grinning at his sexual prowess.

I ride master's length for hours during the night, stopping only when I cum or when his dick is throbbing close to orgasm. I edge his cock so much, I want him to build up his orgasm until it's too much.

And when Master's cock can't take anymore, he unloads his potent seed inside me. It takes all my willpower to not scream as my ass is filled beyond capacity. My tummy swells up until it's round and smooth like a volleyball. "Good boy…"

And despite all my fun, the best part of the night is winding down, cuddling Master after the intense rut. Hugging his strong body and knowing that I have him all to myself.

And that I can do the same tomorrow and the day after that… and the day after that…

You awake feeling sore… As per usual. Lucario seems occupied with cuddling you, though a certain rhythmic squeezing on your shaft tells you another story.

You groan as you hold Lucario close to you and remove the blanket, seeing the mess he left from his nightly debauchery. "This is gonna be a long bath." You say, sitting up and carefully lifting your sleeping Lucario with you.

You reach under him and remove your shaft from his used ass, blobs of cum dribbling out of his ass from being kept inside over night.

"Maybe I should've taken you to the breeders all those years ago." You say with a chuckle, petting his head before carrying him to the bathroom.
