More changes...

Addie awoke to the sound of her mother groaning softly. She was shuffling in her sleep and muttering half spoken syllables to herself. Her tossing and turning preventing Addie's own rest, but seeming oddly cute despite the newfound twist in their relationship.

Assuming she must be having some strange dream, the son turned daughter gently wrapped her arms around her mother's back to calm her. Monica's breathing steadied from the contact, and for a few minutes the two regained their peace.

However, moments later, Addie, still half-lucid from her recent stirring, noticed a change in the grip around her mother's waist. The subtle contractions of her breathing pulling her arms ever further apart. Thinking that Monica must be having another nightmare, Addie opened her eyes once more. But, upon doing so, found her just as soundly asleep as she had left her moments ago.

Squinting in the dark, Addie noticed that something else was amiss, her mother looked off in a way that initially confused her. Nonetheless it eventually hit her, Monica was growing! Addie frantically shook her awake.

"Mom, something's happening! Get up, get up right now!" Addie exclaimed.

"Honey, calm down, you already told me about it, let's get back to bed I'm exhausted..."

"No, not that! Something else, come on come on!"

"Fine fine" Monica yawned. Stretching slightly as she shuffled herself off the bed.

When Monica's feet hit the floor her eyes went wide, she realized instantly what was amiss. She was definitely taller than she once was.

Never before was she able to reach the floor with the flats of her feet while seated there, but now she was tall enough that this happened easily. Her legs were flush with the right angle of the mattress' edge as she sat there in stupefaction. But it didn't stop, soon her knees seemed to be rising slowly upwards as she felt her bones creaking and straining uncomfortably.

Monica shot up and walked towards the light switch, flicking it on as she continued to change. Her growth fortunately slowing and petering out moments later. Addie watched in awe, her mother now towered above even her former height as a man, but for some odd reason she still had the same proportions she had before. She hadn't merely gotten taller, she had become bigger all around, reaching a height of around seven feet while retaining her form and figure.

Monica was panting after the ordeal, and trudged back over to the bed to plop herself down. After falling face-first and turning her head towards her daughter she let out a deep sigh of relief.

Monica muttered, "I'm glad it stopped there, any larger and I might have trouble fitting through doorways."

"I'm more concerned with you fitting somewhere else. Mind if I take a peek?" Addie inquired, blushing slightly and gesturing downwards.

"Hah, I figured you'd ask as much. How could I deny my cock obsessed daughter. Let's have a look." said Monica flipping herself over.

Her cock was already starting to get hard, the effect of her daughter's presence not dampening in the slightest, but despite the semi-hard state, the formerly huge member was evidently much larger than before, having gained size in tandem with her body.

"God, I can't wait to test this out, let's see what you look like at full mast." giggled Addie, shuffling in between her mother's legs and tasting her new and improved prize.

She littered the massive shaft with little pecks, feeling its growing heat and the steady tightening of the soft skin as her mother bit her lip and gripped the edge of the bed. Addie wrapped her tiny hands around the base of the shaft as she continued her ministrations, squeezing the powerful organ tightly and watching it bulge outwards as she traced its underside with an extended lick. The cock now so long her tongue became dry before she managed to reach the head. Licking her lips she then kissed the tip deeply and intimately. Getting what she could fit of the head inside of her mouth and circling her tongue slowly around it. The spongy flesh proved an excellent kisser, gently pushing back against her tongue in time with the steady thump of her amazonian mother's heartbeat. The monstrous organ fattened and rose in response to its expert handling, and started supporting itself with its own turgidity. The steely shaft now pushing aside the dainty fingers that had dared to squeeze it before.

"Wow, you're amazing! This has to be the biggest cock in the world, it's barely human." Addie exclaimed, shifting back slightly to get a better look.

"I wished you would have phrased that differently dear, but thanks. Do you think it will fit?" Monica inquired.

"It will either fit or I'll make it fit. There's no way I'm not having this in me every single day, it's too perfect."

With that Addie knelt between her mother's legs at the edge of the bed, not wanting to neglect her mother's balls. The orbs, like the rest of her body, had increased in size to match her new stature. Formerly the size of large eggs, now they were more like baseballs. Addie reached out and gently cupped one in her hands, testing its weight and squeezing it tenderly. They were unreal, each could barely be gripped in a single palm and weighed a few pounds. Addie silently wondered how much her mother could cum, but quickly stopped daydreaming and got back to her task. Releasing the sensitive sphere from her loving grip she leaned forward and began to suck at Monica's new and improved pouch. Pulling the hairless skin with the light suction of her lips as she licked and polished the virile spheres worshipfully. From this angle smell of strawberries and spice hit her nostrils, and her head went cloudy with lust as she assaulted her mother's nethers with affection.

Above her, Monica still lied on the bed staring up at the ceiling as her dutiful daughter visited wonders upon her newly enlarged form. She was biting the knuckle of one hand and gripping the sheets with the other, moaning involuntarily every few moments. From this angle she couldn't even see what was happening below, and therefore missed that her transformations were not nearly done, only feeling an oddly strong tightness in her erection.

Her cock throbbed angrily, as if furious to be ignored. The shaft became reddened and its veins bulged wildly as the tip leaked copious precum down the titanic spire; eventually wetting Addie's hair and causing a nut-stifled giggle, but never distracting her from sucking. Up above, Monica's cock began lurching left and right with each throb, the frightening vascularity and blush dampening slightly with each lurch. The cock was growing and swaying up and up with each beat, as if housing a creature wriggling upwards for room. Eventually this process came to an end, and Monica's cock stood straight up, now even more massive than before.

Addie, despite enjoying herself thoroughly, finally released her mother's balls from her lips and fell backwards clumsily, surprised again at her mother's transformation. But before she could speak, Monica interrupted her.

"That was amazing dear, but please get back for a second, I don't feel right."

Monica stood up from the bed and stumbled towards the center of the room, the same strange pain in her bones returning to her. The tightness from her cock appeared as well but this time all over her body. She closed her eyes and grunted as she balled her fists and leaned against the wall for support. From the sidelines a stunned Addie knelt and observed the strangest sight she'd ever seen.

Monica again grew taller, but this time her body grew all over. Her muscles bulged and swelled and creased. Becoming rippled and dense and ballooning monstrously. Her form became that of a hulking ten foot tall bodybuilder, and grew further still. Her cock and balls exploded outwards, becoming cartoonish in size. Her nuts the size of pumpkins and her shaft, a grown man. Monica's groans and pants stopped as she turned around, the ground creaking from her steps, but she didn't meet her daughter's frightened gaze. To Addie's sight, the grotesque titan before her seemed ****, looking past her with half lidded eyes.

Then even faster than she had changed before, the process seemed to reverse. A deep thump was heard, and her form shrank inwards.

THUMP. Again her flesh retreated, her height and musculature returning to human record if not its norm.

THUMP. She looked toned but no longer masculine, her height just a bit taller than before this newest development.

THUMP. And it was over.

Whereas Monica was beautiful before, now she was otherworldy. She had not simply aged back a few years, she had become something else. The skin of a genetically blessed teen, with curves that tread the line between a professional dancer and her matronly former self. Glowing with unnatural vitality and beauty, she now stood just under seven feet tall, and began walking towards her gobsmacked daughter. She moved with a sort of poised deliberate languidness, like chilled smoke, and yet with each step the floor still creaked underfoot.

Addie, absolutely speechless at what she had witnessed, still couldn't crush old habits. Her eyes trailed downwards towards her mother's package. There she was greeted with a sight that flushed her mind with a confused onslaught of emotions. Her pussy gushed like a fountain as she shuffled backwards, unsure of what would come next.

From her mother's groin hung an absolute monster of a penis. A fifteen inch fist-thick flaccid cock draped over nuts the size of grapefruits swung low and heavy between her mothers legs. Her steps so gentle and fluid it never quite slapped them, instead teetering hypnotically before Addie as she sat against the wall leaking puddles onto the floor.

When her mother finally reached her, a long silence hung in the air. Addie, relieved that her mother seemed conscious, broke it by saying,

"Mom are you ok? What even happened, did that hurt? That was beyond intense!"

"Relax Addie, I'm fine. More than fine actually. I feel incredible." Monica chimed, her voice even sweeter and more reassuring than usual.

Despite this, Addie couldn't help but stay uneasy. More than assured of her mother's health, now she was less than sure of her own. Her mother, instead of helping her up, had placed her hand on the wall above her. Addie, looking upwards at her mother's beaming face, laughed uneasily as Monica's frame now trapped her below. The wall cracked slightly around her mother's palm, and drew Addie's attention sharply behind her. But before Addie could wrap her head around the situation, she was smacked in the face by a "drop" of precum more than twice the size of any man's load.

Above Addie's head, her mother's cock proudly lanced forward, now twenty inches in length. And drooling its frightening eagerness all over itself.

"Uh... mom, what were you planning on doing with that?" Asked Addie, pointing meekly at the pulsing appendage.

With the same eerily unbroken smile Monica responded,

"Oh that's obvious dear, I was just going to..."
