Aaron's definitely going to need a little help.

"Huh." Lily was right, Aaron had to admit. His cock was about two feet long, if not more, and his nuts had reached the size of basket balls, pulling on his scrotum with their considerable weight. Kneeling worked, but only because his balls and more than half of his dick rested on the floor. "Well, maybe I can..."

He could, but only just. Aaron took his enormous two-footer into both arms, hugging it against his body, the upper third flopping over his arms and hanging downwards, still drooling cum. Getting first one foot under him, then the other, Aaron managed to slowly rise to his feet - and realised the problem he now faced. His balls were heavy, yes, but the weight wasn't even the problem. Standing bowlegged, he managed to fit them between his knees, but walking with two gigantic orbs proved more than just difficult. Every time Aaron tried, he almost lost his balance due to the heavy, swinging scrotum.

"Okay, I thought these were impractically huge, but you're obviously worse off," Lily mused, jiggling one tit with each hand. The sight of quaking boobflesh made Aaron's mouth feel dry, a weak throb racing through his overly long pole.

"Y-Yeah, they seem hard on the back," he stammered, unable to take his eyes off Lily's enticingly wobbling chest.

"Funny enough, they aren't. My back muscles must have gotten an upgrade, or maybe I'll feel it later," the blonde replied, shrugging and letting her arms fall to her side, revealing her enormous, stiff nipples and giving Aaron another reason to stare.

"C'mon, stud boy, I'll give you a hand or two," Lily giggled after shaking her breasts from side to side, Aaron's eyes following their stiff tips' every move. Still giggling to herself, she stepped behind Aaron and cradled one of his nuts in each hand, lifting them behind Aaron with a surprisingly cute grunt.

"Wow, these are heavy!" The blonde sounded impressed. "Even though you just came so much!"

"Don't ask me how that works. With all this jizz around here, I should be dead!"

"I just more than doubled my cup size and you grew a cock like a tree trunk. Logic went out the window when we ate those candies, I'd say."

"You can say that again..."

"Alright, let's get cleaned up. Your cum feels awesome, but only if it's fresh, if I'm honest. The bathroom is upstairs."

With his huge balls now pressing into his ass cheeks, Aaron felt like he could try to walk again. With Lily directly behind him, he began slowly making his way to the stairs and then up and to the bathroom. They could hear some muffled cursing and banging noises from the room at the end of the hall, presumably James', but wordlessly agreed to ignore them. At first.

"Oh my fucking gaaAAWWWD," James suddenly yelled from his room, his voice rising in volume at the end - and in pitch. He sounded somewhere between terror and bliss.

"What the--" Aaron began, only to be interrupted by Lily.

"Oh shit, that sounded... come on, waddle over, we need to check on him!"

"But what--erk!"

Feeling himself steered by his nuts, Aaron had **** but lead the way towards James' room. As they neared it, they could hear loud panting and feminine moans. Was James actually...

"Is... is he watching porn? Should we really..."

"Maybe he is, but the scream sounded serious. Maybe he hurt himself. And even if he's just masturbating, he'll be so embarassed if we just barge in on him," Lily replied, a mischievous tinge to her voice.

"Not like I have much choice," Aaron groused, earning a playful squeeze on his nuts.

They quickly reached James' room, and Aaron let go of his giant schlong with one hand to push open the door. When the pair saw what was going on inside, their jaws dropped - as did Aaron's balls when Lily let go of them.

In the middle of his room, James was indeed masturbating. But not, as Aaron had expected, by jerking off; James no longer had the equipment. Instead, increasingly dainty fingers stirred up a sopping cunt, James' thumb pressing into what had to be a clit, wiggling it wildly. The other hand mashed, squeezed and pulled rapidly swelling breasts capped by stiff nipples, and his face... the person writhing in pleasure on the floor was barely recognizable as James anymore, and as they watched, the last resemblance melted away, James' full, pouty lips forming an 'O' of pure bliss. Big, expressive eyes were half-obscured by eyelids with long lashes, and his shaggy hair was rapidly lengthening into a magnificent mane of red curls. James' entire body was becoming shapelier, passing curvy and quickly approached voluptuous.

But not only his assets were growing - as Aaron and Lily kept staring wide-eyed at the furiously jilling redhead, they realized that his, or by now rather her, whole body was slowly getting bigger. Suddenly, James' whole body seized up, a powerful muscle spasm arching her back, locking her arms and making all movement impossible. Immediately, the growth sped up, Lily's step-sibling quickly gaining at least ten inches in height before the cramp ended and James could continue fingering her gushing honeypot and her growing slowed down.

"Oh fuck, fuck, fuck..." Lily cussed, hurrying over to her not-quite-anymore brother, kneeling down beside her. "James? Can you hear... are you alright?"

"Aaoooh, sooo goooood!" James moaned instead of answering, raising her expanding ass from the floor to get better access to her gushing slit. The breasts she was still relentlessly mauling had reached the size of cantaloupes by now. "I can't... I wanna... hnngh!"

Another cramp seized her, and again she grew, easily gaining a foot before the spasm let up.

"Oh god oh god oh god, what do we..." Lily wrung her hands, suddenly stopping and looking at Aaron. "Aaron, you... you need to fuck her."

Aaron wrenched his eyes away from the comparatively huge cunt dripping with liquid arousal and stared at the blonde.
