Naruto assumed a thinking posture while he tried to decide what to do. He was certainly dense, but years of leading had sharpened his analytical mind immensely. So he had a bigger cock, and everyone else treated like it was normal, even though he was aware of any changes. He needed to try to figure this out more.
"AGH!" He ruffled his shorter hair in frustration, hands feeling the soft but spiky ruffles of his hair. It wasn't getting hard to focus because of the sheer amount of cock he was currently having to deal with. He was already larger than anyone he could physically imagine, minus an Akimichi of course. (Hey, he studied under the Pervy Sage after all!)
He sighed in frustration. How was he gonna deal with this without worrying Hinata. "I need to figure out how to deal with this..." Naruto muttered, making her not worry the top of his priorities. But to do that, he needed to get back to his office and start looking into it! He pumped his fist, fire burning in his eyes to figure this out, imagining himself like that Sheruroku detective fellow Sakura enjoyed reading.
But of course, his mind started wandering back to Hinata's touch, and of course, "Ah shit!" He cussed, feeling his hard-on once again starting to slap against his abs. "Agh! I don't have time for this!" shouted Naruto, even as he slapped his right hand away which was reaching towards it. "No! Bad hand!"
*squeak*
"I need to get that thing oiled." Naruto muttered as his head popped out, looking both ways to make sure no one was looking. Once he saw the coast was clear, he walked out, his clothes heavily tented, his crotch bulging from the pair of basketball sized orbs hanging from his groin, while his shirt had a very obvious tube running up it, pinning his cock against his abs.
Every movement left him twitching, his head rubbing against his bare chest as he gradually felt himself heating up, drool starting to leak out of the side of his mouth as the sensation drove him crazy. He snuck into his room as fast as he could, his face flushing from the extended contact as he felt his body heating up... and heating up?!
"Ungh... fu-fuuuucckkkk...." He moaned, more and more sweat rolling off of his brow as he felt that heat concentrating. "Shi-shiiiitttt.... it's getting bigger!" He reached down as his hand reached down to grip the expanding tube under his shirt. It wasn't all that was growing too, as the groan of his pants reached his ears, the gurgle of cum rumbling from his balls as they continued to expand.
With a rumble, they continued to expand, their tan color starting to show through the gaps in the stitching as they were forced apart. Up above, his cock was inching slowly upwards, teasingly moving past his abs, to the gap between his pecs. It was only getting thicker too as Naruto felt his pulse quicken, blood flowing as the veins on it stuck out. With multiple pings, he felt the buttons starting to ping off his shirt while the head popped out of his shirt, rubbing teasingly against his chin. It was too much for him as he started slurping it, tasting his delicious seed, something he hadn't done in a while.
"OOhhh, *slurp* Oh FUuucckk, Bi-biiiggggerrr! MOOoorrrre!" He gasped, slurping cups of his seed down, enjoying the sweet and salty taste, reminiscent of ramen. He teased his head, licking the inside of his slit, the unique sensation just enough to put him over the edge. "I'mm CUMMMMINNGGG- BLERGH!" his shout was interrupted as the first cum shot burst out, his shaft expanding from the rush of cum bursting open his shirt.
Gasping, the next couple of shirts splatter over his face, and with a wet squelch, his cock shot forward, spurts of white Uzumaki seed shooting out to soak his carpet, blasting out of his 36 inch tube, just high enough to be level with his mouth.
Eventually his release died down, leaving him panting, his massive log softening as it hung down between his legs, reaching at least past his knees, held up by a pair of watermelons. He breathed heavily, breath somewhat fogging up even as he looked at his mess, half of his floor covered ankle deep in his cum. There's no way anyone couldn't not notice that.
"Oh Naruto-kun, breakfast is ready!" Hinata popped in, Naruto going deer in the headlights as she saw the mess. "Aw, if you were going to have some fun, you should've invited me dear!" Naruto was looking slack-jawed at his wife, even his mind having trouble wrapping around this situation. "I know it's hard when you're about three feet long, but don't worry, I'll get it cleaned up soon!" And her door shut.
Naruto's eye twitched. There was no way whatever this... thing that was going on, there was no way it was that perfect, right? Surely there must be something, a loophole or a side effect? Or maybe it really is that perfect...
