Today was the day. I honestly couldn’t believe we’d made it. I know that it was Max and not me who took on this challenge but I somehow felt like it was my accomplishment as well. After all, I had to watch the girl I loved go from cute, to hot, to drop dead gorgeous and then all the way to become a goddess without being able to be with her in the way I so desired. As I was getting dressed I remembered the first night we spent together after she outgrew me.

She was only half an inch taller than me but that half inch made all the difference. That was also the first time she’d lifted me. We recreated the ever popular position where the larger person pins the smaller one to the wall while they make out. Of course usually it’s the guy and not the girl doing the pinning. At that point her breasts were so big that even when we were on level ground she had to lean forward, over her massive chest, to kiss me. 

Jasmine woke soon after I did. She knew what today was as well and seemed eager to head out. She measured herself to spare me the theatrics as we got ready. She, of course, had no clothes to wear and so instead co-opted my bedsheets. They were barely able to cover her rapidly growing assets. 

“7 foot 3.” She whispered down at me with a smile. I could believe it. I was staring straight ahead at her cute belly button. She spun me around and ushered me out the door. As I left I heard a loud *CRACK* and turned to see Jasmine wearing the door frame around her waist. The whole thing had gotten stuck on her ass and she was far too strong to notice the weak resistance it put up.

“Uh….oopsie?” She smiled guiltily down at me. I just sighed. 

“Don’t worry about it, we’ll replace it later.” She grinned and tore the frame in half to loosen it from her butt. Then the two of us went to find Max. 

We found her already outside doing some stretches. She was fully naked, not that I could blame her. Even with her deep pockets clothes her size were expensive and she probably didn’t want to get them dirty. Jenna stood beside her, less than half her height but still towering over us. She waved us over and sat on her knees to meet us halfway. 

“Hey Trev! Jas! You guys ready?” 

“Boy I hope so.” I said looking up at Max. I remembered what Jenna’s first orgasum was like. If Max’s was the same filling the quarry would be the least of our concerns. 

“What’s it like!” Jasmine asked excitedly. Jenna and I exchanged looks. Jasmine likely hadn’t even seen a normal man cum let alone a pent up futa.

“It’s….intense.” Jenna answered. “We’re probably gonna want to watch from a distance.” 

“Hey,” The booming voice of my girlfriend sounded from overhead. “I’m about ready, you guys wanna ride with me?” She was standing over us, her prominent ankle bone right at my eye level. 

“Can we!” Jasmine seemed to be vibrating in place in her excitement.

“Sure!” Max giggled and reached down to gently grip Jas and myself in each of her hands. She lifted us up to sit on her shoulders. “Hold on tight!” She said as she began walking. I gripped her hair and noticed that it was once again longer. Of course it was longer, at this size it would be longer than I was at almost any length. What I meant was it was longer in proportion. At the start of the month Max’s hair barely touched her shoulders, now it’s red tips fell down past her elbows. That probably made her hair over 15 feet long. 

As we walked Max’s cock swayed in front of us. We’d last measured it at just over 55 feet long. It looked far longer now. Max must have noticed me staring because she soon spoke.

“There’s gonna be a whole team waiting for us there, They’re gonna do one final round of measurements and then you are gonna get to work.” 

“Get….to work?” I said, perplexed. Max's smile widened. 

“How else do you think I’m gonna reach my climax? Besides, I want my first time to be with you.” Her first time? I guess it was but usually when girls said that they meant first time having sex, not “First time having your tiny boyfriend jerk off your 100 foot dick”. Nevertheless I was flattered and eager. 

We arrived much sooner than I expected. I guess when you’re walking stride is over 20 feet long you can get around pretty quick. Just as Max had said there was a team of General Trent’s soldiers waiting for us. 

“Agent Diana, Agent Xena.” Trent spoke through a megaphone. “We are prepared to take your final measurement. 

“Can we save it until after?” Max asked “I might grow a bit more in the process.” The General consulted with some men and women in lab coats.

“In that case we’ll do a before and after, is that acceptable?” Max nodded and stepped on the massive scale. There was a flurry of action around her feet while the numbers were calculated. 

“It appears you weigh 247 tons and stand 50 feet 10 inches tall.” Trent finally yelled up at Max. 247 tons, most of that probably came from her massive cock and balls at this point. Even so, it was astounding. “We can’t measure you’re, uh privates, since it seems to be longer than our scale.” Trent continued. 

“And how long is that?” Max asked innocently. 

“100 feet exactly.” 

“Oh my.” Max feigned embarrassment and placed a hand over her mouth. “I guess I’m just too big for the General’s little toys!”

As she prepared to do the dead Max placed Jasmine on the ground by the safety screens Trent had set up, despite her pleas to get a front row seat. I guess only I got that honor. Max positioned herself at the edge of the quarry. Her cock was more than half as long as the quarry was wide and so hung out near the opposite edge. 

“You ready? Little lover?” Max whispered as she placed me in the palm of her hand. I could only nod. “Good!” With that she lowered me down to place me on her stiff member. 

I stood shakily, her cock was far firmer than I’d anticipated and it felt almost as solid as concrete. I could feel her pulse through my bare feet as I walked down its length. Everything about it was massive. A vein thicker than my leg pumped her warm blood just past my footsteps as I approached the tip. I looked back at Max’s face, more than 100 feet away and nearly 30 feet above me. She smiled reassuringly as she placed her hands around the base of her cock and started slowly moving them back and forth. It took a measurable amount of time for the vibrations to reach me but when they did I was knocked on my ass. Max was already lost in her pleasure. 

I looked around frantically for something to do. Finally I settled on kissing and caressing the exposed tip of her cock. I knew it had an immediate effect as Max moaned in approval and I redoubled my efforts. I could feel her cock rapidly warming and pulsing beneath me. To my surprise I also noticed that it was actively growing, as it crept closer and closer to the other side of the quarry cliff. A massive stream of precum bubbled from the head and I made sure to keep my distance. I could hear it splash nearly 100 feet below me, already starting to fill the lake. It didn’t take long for Max to reach her limit. In one motion she angled her cock down into the quarry to prevent any cum from shooting out of its confines. I held on for dear life as she let out an earth shattering scream of pleasure. 

A thick white substance rocketed from her cock. It plowed into the lake below, already nearly twice as deep thanks to her precum. It burrowed into the stone bottom carving out another 15 feet of depth. Even though Max had pointed her dick downwards I suddenly had the unmistakable sensation of vertigo. I looked to the far cliff of the quarry and saw it sinking further and further below my sightline. I then looked up at Max’s face and saw it receding away. She was growing just as Jenna had. The skin of her cock spread out beneath me as it grew with her, and still she came. Rather than becoming depleted it looked as though her testicles were swelling even further. A horrible thought crossed my mind. What if she never stopped? What if she just kept cumming and growing forever? 

I wasn’t given any time to be anxious about the future though as the present demanded my immediate attention. My grip was loosening. As Max grew I had to continually adjust my position and soon it became too much. A single gasp escaped my mouth before I found myself falling. I mustn’t have been too high above the rising tide of Max’s cum as I only fell a few seconds before I was surrounded by her steaming semen. It was remarkably easy to keep my head above water, er cum, as long as I gave the fountain spewing from her dick a wide berth. The entire mass undulated and tossed me around. I noticed that the top of the cliff was rapidly approaching and with no end in sight the lake of cum quickly overflowed the quarry’s banks. The General and his men had already evacuated but Jenna was still standing there. She was gazing up in awe at Max’s growth even as he semen pooled around her ankles and continued to rise. 

Max’s body was eclipsing the sun from my position. Still she came. Soon even the tree tops were threatened and even Jenna found herself unable to touch the surface under the ocean of cum. Eventually though, the tsunami flowing from her titanic cock slowed. The last few hundred gallons fell in dribbles and drops. In the end Max had overfilled the quarry and her seed rose all the way to her own knees, though it was slowly falling as it spread out. Her cock, no longer hard, slowly shrank away and lowered. It was still long enough to rest on the ground from where she stood and was thicker than her legs. Even her balls reduced in size, though they were still about as large as they were this morning. But with Max’s new height, whatever that was they seemed much more manageable. 

I was still floating freely in her sea of cum and as she bent over to look for me I wondered if she’d even be able to see me. Luckily she could and she reached down to try and fish me out. She licked her index finger and gently placed it on my tiny body. She was able to pull me up and out to meet her gaze. She was gigantic. Her eyes alone looked larger than my body and I could tell her finger was easily more than twice my height. 

“Hey little lover, like what you see?” Her voice was soft and low, even so it was so loud it drowned out all else. Her full volume would probably kill me at this range. I smiled up at her and gave her a thumbs up. She grinned and then placed her finger to her lips, pinning me in a kiss.   

In the aftermath we determined the full extent of her growth, with the help of Trent’s team. It took some jerryrigging but we were able to figure it out. The final score is as follows:

Height: 250 feet 1 inch.

Weight: 21,234 tons

Penis Length: 98 feet soft, 302 feet erect.

Balls: 44 feet in diameter and 5,102 tons each. 

More than three quarters of her weight came from her cock and balls combined. She now stood as tall as the two story house she’d just built and I couldn’t even imagine the scale of the next one. But more than that, I was almost sad it was over. I guess a part of me wanted Max to just keep growing forever. But all things must come to an end. I may only have gotten to experience this once in my lifetime but I wouldn’t have wanted to do it with anyone else. I guess that marks the end of this diary, for now. I hope everyone who read this enjoyed it as much as I enjoyed experiencing it. Until next time!
