Lucas was a Lucario at Pokemon University, a private school where only males were allowed to attend. School had just resumed after summer vacation, and it was now Lucas’s senior year. He had taken the swimming class elective this year, as he had every other year, if only so he could gaze at the well-hung jocks, naked in the locker room after class. One jock in particular had caught his eye this year, a senior Zoroark by the name of Adam. At the beginning of their freshman year, Lucas remembered Adam’s dick being no bigger than his own average six incher, and he really never thought anything of him. That all changed when he came back as a sophomore, and his penis seemed to have grown by a full two inches, becoming eight inches in length. Now that the Zoroark was a senior, his shaft had grown yet another inch, reaching nine inches in total, and thickening up to match.

While Adam’s manhood sprouted, the Lucario’s own cock hadn’t grown a bit since his freshman year, remaining at a paltry six inches. Some part of Lucas didn’t mind though, instead he felt aroused whenever he watched the well-endowed jocks in the locker room. Often times he couldn’t help but get a boner after class, and his big-dicked classmates would tease him, and call him names. Almost every day he heard them talk about Little Lucas getting another hard-on from seeing a real man’s penis, and their words only made his shaft harden even more. Today was no different, with swimming class having just ended, and all the Pokemon having stripped off their swimsuits in the steamy locker room. The Lucario was sitting on the bench in front of his locker, his swimming trunks still on, but with a clear bulge sticking out from them where his hardening cock rested.

Lucas was in a daze, glancing back and forth at several of his classmates, their dicks bobbing around as they walked along. Suddenly a voice knocked the Lucario out of his trance. “Hey, Lucas.” Lucas’s eyes shot up, and his paws covered his crotch, or at least attempted to cover the obvious tent in his trunks. “Oh, A-Adam! Hey, uh… w-what is it?” The Zoroark jock now stood before Lucas, his big shaft hanging just below the Lucario’s nose, making the latter’s eyes drift down unintentionally. “You’ve been checking me out a lot this year, haven’t you?” Lucas blushed, and quickly looked up. “Oh, w-well I uh… I mean-“ Adam cut him off. “It’s no secret you’re always checking everybody out, Little Lucas. I know you like my dick, and you like how it’s bigger than yours, so don’t give me a raft of shit. You can’t fool me, bitch.” The Lucario flinched, averting his eyes. “Well… y-yeah… I do…”

Lucas gasped as he felt the gentle touch of Adam’s clawed paws upon his face, forcing him to turn his gaze back up to the Zoroark’s eyes. “Listen Lucas… I have to ask you something…” The Lucario nodded as Adam released his head. “S-Sure, uh… what is it?” The Zoroark smirked. “You like how big my penis is now, but what if I told you that you could watch it grow even bigger before your very eyes? Wouldn’t you enjoy that?” Lucas gulped. “I uh… I mean yeah… h-hell yeah I would… but that’s not possible… right?” Adam grinned, and pulled a phallus shaped idol out from behind his back, holding it in front of the Lucario. “Oh it’s possible with this thing. You see each year I can use it one time to suck out the manhood from another Pokemon, and give it to myself, making my shaft larger every time. For each inch I drain, an inch is added to my cock, and I’ve managed to add three since I came to university.”

“I was hoping you’d be willing to… you know, donate an inch or two of yourself to me, since you obviously can’t get enough of my big fat cock.” Lucas couldn’t believe what he was hearing. “Y-You can what?! So that’s why you’ve gotten bigger every year?” Adam nodded. “That’s right, Little Lucas… now why don’t you take your trunks off so we can get started? I’m getting hard just thinking about this shit.” Surely enough, the Zoroark’s nine inch pole was beginning to harden, growing ever closer to Lucas’s snout as it rose slowly up. The Lucario stuttered. “B-But you said it drains the other Pokemon’s manhood… doesn’t that mean I’d get smaller if I did this with you?” Adam growled, shoving Lucas down onto his back upon the bench, and grabbed his trunks by the bottom practically tearing them free from his body, and allowing the Lucario’s hard-on to bounce free. “Just shut up, and enjoy what you're about to do for me, bitch! I need this a hell of a lot more than you ever will anyway!”

Lucas cringed as the Zoroark yelled at him. He should’ve tried to run away, or yell for help, but he just couldn’t bring himself to. Some part of him loved being treated this way, and for Adam to approach him like this was almost some sort of fantasy. The Zoroark straddled the bench, sitting himself down upon the Lucario’s thighs, and letting his heavy nine inch penis rest down upon Lucas’s own smaller six inch shaft. Only now did Lucas realize that Adam’s balls were easily twice the size of his own, as he could feel their weight pushing down upon his sac, causing a bead of pre to form at the tip of the Lucario’s cock. Lucas winced as the Zoroark reached the phallus shaped idol out to him as he glared down from above, the fluorescent lights casting a dark shadow over Adam’s form, making him look menacing. “Hold onto this with both hands, and don’t you fucking let go of it until I tell you to, understand?!”

The Lucario gingerly took the idol into his paws, holding it against his chest as he felt a strange tingling sensation build up in his penis, while Adam grinned widely. “Good bitch… now just relax, and stare at my cock like you’d do anyway. Let that thing work its magic, and give me some of your manhood.” Before long, the tingling sensation became a pleasurable one, eliciting a moan from Lucas as he felt Adam’s dick throb atop his own, thickening ever so slightly, while it grew a little longer, and the Zoroark’s balls became a little bigger. As much as Adam’s package had grown, surely enough, Lucas could see, and feel his own endowments shrink. It was only a bit at first, but he was quickly overcome with another pleasurable pulse as Adam’s shaft swelled a second time, and his own prick shriveled.

The Lucario stared in awe as the Zoroark’s dick and ballsac throbbed, and expanded bit by bit, while his own penis and balls diminished slowly but surely, until it was clear that an entire inch of his manhood had been drained from him, and fed to Adam’s heavy shaft. The Zoroark laughed as Lucas continued to stare at the sight before him, completely in shock. “You really can’t get enough of my cock, can you Lucas? I’d say it must be at least ten inches now, don’t you think? That leaves you with what, five inches? That’s pretty small, but I think you could stand to give me some more… what do you think?” The Lucario hardly heard Adam’s words, instead focusing his attention on the weighty shaft, and sac pressing down against his increasingly meager package. Lucas didn’t bother responding, instead he only moaned when another wave of pleasure hit him as the Zoroark’s cock expanded once more, leeching a bit more manhood from him, and fattening itself in the process.

Every throb, every pulse of Adam’s knotted shaft saw it grow thicker, and longer, his balls becoming bigger, and heavier. All the while the Lucario’s penis only shrunk more, looking less than average, as his sac appeared to grow less virile by the second, getting smothered under the Zoroark’s swelling orbs. Adam sighed deeply as he smiled down at Lucas, reaching out his paw to caress his cheek. “Look at me now, Little Lucas… heheh, of course you already are. I’d say I’m a good eleven inches long thanks to you… and just look at my nuts. I wonder how big my load will be now, hmm? A hell of a lot bigger than yours, that’s for sure, just look at you. You’re hardly even four inches long now… what a pathetic bitch!” The Lucario flinched, but never took his eyes off of the growing phallus before him, seeming to be transfixed upon it.

Releasing Lucas’s cheek, Adam sat back, and groaned as his penis enlarged yet again, the idol in the Lucario’s paws feeding more manhood into the Zoroark, who consumed it all too willingly. “Ah, f-fuck yeah… You know, most Pokemon would’ve made a big scene by now, and I would’ve had to bail before I got in trouble… but not you, huh?” Adam reached down to pet Lucas’s head as the Zoroark’s shaft grew thicker, and longer bit by bit, his balls becoming fatter, and heavier all the while. The Lucario remained silent, save for the occasional moan as his prick shrunk slowly shorter, and thinner, his nuts becoming shriveled, and barely productive. As Adam’s cock grew to a full foot long, with thickness to match, it now completely obscured Lucas’s little prick from view, along with what little was left of his sac that was being utterly crushed underneath the weight of the Zoroark’s swollen, cum bloated orbs.

Releasing the Lucario’s head, Adam smiled softly down at him, seemingly satisfied. “You know, I’ve always wanted a twelve inch dick, and now thanks to you, I finally have one. Fuck, in three years I didn’t grow this much, you know? Just look at my fucking nuts! I could burst an extra large condom with these babies, no doubt!” The Zoroark’s smile faded as he looked menacingly down at Lucas who seemed to have no will to stop him from taking everything he had. “But just look at you now… you’re what? Three measly inches? That’s hardly even a prick… and what are those, your balls? You couldn’t get someone pregnant even if you tried! What a fucking little bitch! But you’re not done yet, are you…? You’d like to see me get even bigger, wouldn’t you Little Lucas…? Isn’t that right?” The Lucario breathed heavily, realizing he had been in a trance for quite some time, but he also realized Adam was right. He didn’t care if he even had a dick after this, so long as the Zoroark’s phallus kept growing, he’d keep watching it grow, over and over again. “Y-Yes… I-I… don’t want to stop… I don’t care… this is… a-amazing…”

Adam laughed cruelly as he felt his massive package expand once more, leeching the manhood from Lucas without abandon, making his already pathetic cock and sac shrink further while the Zoroark’s phallus grew past twelve inches, swelling thicker with every heartbeat, his fat balls sucking the seed from the ones underneath them, becoming heavier, and larger still. The Lucario cried out as he felt himself climax under the weight of Adam’s huge package, releasing a pathetic single shot of cum that was all his shriveled balls could manage. Lucas panted as he felt another surge of pleasure, and the Zoroark’s giant manhood began to swell again, but he gasped in surprise as the idol was forcefully pulled from his paws by none other than Adam himself. “Alright Lucas, that’s enough for today… I don’t want you bitching at me later because I took your whole dick, and you wanted to have kids or some shit. Of course everyone knows you're gay, but whatever…”

The Lucario shook his head, and tried to reach for the idol, but Adam held it away from him. “W-Wait! Why did you stop? You said you could only use it once a year so-“ The Zoroark cut him off. “Look bitch, if you still want me to take your whole cock next year, then I’ll suck you dry, okay? Next year! Just be happy you got to make my big dick even bigger for you to gawk at every day, you fucking queer prick!” Lucas whimpered as Adam stood up, and got off the bench, grabbing the Lucario by the shoulders, he sat him up as Lucas looked like he could cry. The Zoroark cringed at the Lucario’s expression, and reached behind his back to grab a piece of paper with a number written on it. “Hey, don’t you fucking cry on me now. Here, take this… It’s uh… my number.”

Lucas looked surprised, but took the paper into his paw. Adam leaned down to surprise the Lucario even more, forcing a deep kiss onto him that saw the former’s tongue snake its way into the latter’s mouth. Lucas’s eyes went wide at first, but became sleepy as he went limp in the Zoroark’s steamy embrace. A string of saliva remained between their lips as they parted their kiss, leaving the Lucario breathless. Turning himself around, and walking slowly away, Adam glanced back over his shoulder. “Give me a call sometime alright? I’ll take good care of you Lucas… you can bet on it baby… heh… and thanks…” With that, the Zoroark waved before going back to his own locker. “See you tomorrow, bitch.”

The Lucario just sat there in shock, looking down at the paper in his paws. “Did he just… a-ask me out?” Looking a bit farther down, Lucas gasped at the poor state of his manhood that had deflated incredibly from their exchange. “Oh f-fuck… what the hell did I do…? I guess… there’s no going back now…” The Lucario gulped, and reached for his trunks. Somehow he knew this year was going to be much longer than any of the others he’d been through. The name Little Lucas was more accurate than ever, but then again, the thought of coming to swimming class tomorrow still turned him on. The difference between him and the jocks had grown considerably, and so would the pleasure he got from seeing how much bigger they were than him.
