I woke this morning to my phone buzzing on the bed beside me. I groggily unlocked it to find several texts from Jenna. 

-Hey can I come over?-

-U up?-

-I just need to get outta the house for a bit-

-I’m borrowing your car see u soon-

Immediately after reading the messages there was a knock on the door. Max groaned and rolled over, inadvertently sending me carrening off the bed. She didn’t seem to want to wake up just yet. I made a quick pit stop at my room to get dressed and then carefully made my way down the stairs. I was so small now that they nearly came halfway up my body. When I reached the door I realized that I couldn’t actually open it. The handles for the main door were 6 feet off the ground, well out of reach. So instead I opened the smaller door ment only for me. I peered around the front step until my eyes met with a pair of thick thighs. I really should start looking up first. 

“Trevor?” I looked up to see Jenna’s face far, far above me. “Hey, sorry for coming over so early, can I come in?” She looked tired and slightly upset. I noticed she was wearing what looked like toga made from bed sheets. 

“Yeah, sure. Uhm...I can’t exactly open the main door though so you’re gonna have to squeeze through here.” I motioned to the tiny doorway I’d opened. Jenna frowned and knelt down to get a better look. The door was exactly 5 feet high and less than 2 feet wide. Jenna was both significantly taller and wider than this so it was gonna be tough. I moved back to give her some space as she got down on her hands and knees to crawl through. She was able to angle her wide shoulders through without much trouble and her deceptively narrow waist was no problem at all. The real issue was her ass. My sister had always been kinda hot, as much as I tried not to acknowledge it, and most of this came from her large butt. Even before she started growing she was probably wider back there than I was, and now? Well now her overflowing ass was more than double the width of my tiny doorway. 

“I think I’m stuck, can you give me a push?” Jenna shouted over her shoulder. I hesitated, my hands hovering over the mountains of flesh before me. “Trevor?” She insisted. 

“Yeah, okay!” I yelled back and placed my hands on her rear. I pushed for all I was worth. My hands sunk into her soft skin before meeting a layer of firm muscle. No luck. I braced my shoulder against her and heaved as she strained on her end. It seemed futile, she was just too big! But then there was a groan, a creak and finally a SNAP and she lurched forwards. I would’ve fallen on my face but I ended up landing on the sheet she was wearing and got pulled through the door. 

“Phew! Thanks little bro!” Jenna stood, stretching her arms.

“Yeah no problem.” I said, dusting myself off. I looked back at the doorway to see the frame had blown out around where Jenna’s butt had stuck, leaving a comical imprint in the wood. 

“Ah, sorry about that. As you can see I’ve gotten really big, really fast. That’s actually kinda the reason I’m here….” She said sheepishly, twisting her hair between her fingers. 

“Come on,” I motioned to the kitchen. “You can tell me all about it over pancakes.” Jenna’s eyes lit up and she followed me happily. 

I, of course, was too small to actually use the kitchen but Jenna was just able to reach most of the countertop. For anything she couldn’t reach she’d simply lift me above her head to grab. After about 20 minutes we were sitting down with our pancakes. Jenna had a large stack of 5 while I had just the one. Even so she had forgotten how small I really was and had made me a huge pancake almost a foot and a half in diameter, just like hers. As we began eating she began talking. 

“So I’m really tall now, like really tall. I’m 6’8” according to the ruler in your room. I’ve talked to some other girls and they say that everyone grows differently. Some people have like a sine curve, some people are exponential and some people, like me, are linear. I’ve grown 6 inches a day since I started, 'cept for the first day I only grew 4.” I nodded silently, not wanting to interrupt. “Anyways, Dad’s been all over my back since you moved out. He keeps trying to hint that I should just cum and stop growing but he’s too afraid to actually come out and say it. But this morning I was looking for something to wear and he just barged into my room. You shoulda seen the look on his face! I don’t know how big his dick is but it has to be smaller than. And he couldn’t stop staring! Then he started yelling about how I should cover up and I told him if he wanted me to cover up he should buy me some new clothes. We argued for like half an hour before I just couldn’t take it anymore.” She paused to swallow the last of her pancakes, I still had more than ¾ of mine left and was already full. “I made sure to get real close to him, his head only comes up to, like, my shoulders now. I'm more than a foot taller than him and I think my tits nearly knocked him over. He tried to push me away but I couldn’t even feel it. He just ended up pushing himself back. That’s when I grabbed a sheet from my bed and came over here. So that was my morning, what about you?” She finished abruptly and placed her head on her hands, smiling sweetly over at me.

“My morning? Uh, this. It’s been this.” I gestured at her beaming face. “Are you sure you’re okay? Max can probably spot you some money for clothes if you need them and I think we have a guest room but you should probably try talking to Dad at some point.” I was trying to be reasonable without invalidating her feelings, I might be a midget but I was still her big brother. 

“Yeah,” Jenna sat back in her chair and sighed. “You’re right I know. It’s just so frustrating. Mom’s basically just been ignoring me and Dad’s been so insecure about the whole thing. Like somehow the fact that his daughter is a foot taller than him and has a bigger dick than he does makes him less of a man.”

“Don’t forget you’re way stronger than him too.” I pointed out, trying to make her feel better. It worked because Jenna grinned.

“Oh yeah, way stronger.” We both laughed. Then we set about cleaning up. I say we but Jenna did most of it. She placed me next to sink where I held a dish cloth as large as a bed sheet to dry the dishes. 

Just as we were finishing up we heard the staircase creak.

“That must be Max, finally awake.” I said, motining to Jenna to lift me off the counter and place me on the floor. Once down I ran to the stairs just in time to greet Max. 

“Hey babe, sleep well?” I teased.

“Wha? Oh, yeah I slept fine.” Max said, her voice bereft of emotion. She looked slightly sad from my low perspective. 

“Hey is everything alright?” I said gently moving closer. Max leaned over to lift me up. 

“Yeah, kinda.” She said, kissing me loosely. Just then Jenna came around the corner. 

“Hey Max, sorry for coming over unannounced I hope that’s okay?” Only in front of Max could a 6’8” amazon look like a child. 

“Yeah it’s fine.” Max said, once again monotone. 

“Hey, something must be up. Come on you can tell me.” I pleaded, I didn’t like seeing her like this. 

“Well….” Max avoided my gaze for a moment before continuing. “I’ve….stopped growing.” Both Jenna and I stood in silence for a few seconds at this news. 

“Stopped as in, completely?” I asked.

“I don’t know,” Max sighed. “All I know is that I’m the same height, weight and have the same size dick today as I did yesterday.” 

“Wait when did you measure?” I was even more confused now.

“Just after you woke up, there’s a scale and measure in the bathroom.” Ah that would explain it. I was too small to use her bathroom and so had never bothered entering it. Jenna stepped forward, eager to comfort Max.

“I’m sure it’s just temporary. I heard that some futa stop growing for a couple days and then BOOM they grow, like, a foot in one night.” She waved her arms to emphasize her words. Max perked up at this.

“Really? That can happen?” 

“Oh yeah! I heard this one girl was only like 6’2”, stopped growing for 3 days and then the next morning she was seven and half feet tall with a dick a foot longer than before!” Jenna continued. “Besides it’s probably just ‘cause it’s Friday the 13th, some kinda cosmic joke.” Max giggled at this comment.

“Maybe you’re right, either way I shouldn’t let it get me down, sorry guys.” I leaned in to kiss her large, warm cheek. 

“No need to apologize baby. And remember, you’ll always be an amazon to me! My perfect big tiddy goth girlfriend.” Max blushed at this, I could feel her cheek radiating heat as the blood rushed through.

“She’s more than an amazon just to you,” Jenna laughed. “She’s ,like, a full foot taller than any other futa I’ve ever met. And your dick is already the largest in the world right?” She motioned to Max’s semi-erect penis that was lifting her nightgown off her frame like an enormous, pulsing telephone pole. Max blushed even harder.

“Yeah I crossed that milestone ages ago.” Then she eyed Jenna curiously. “But what about you? You’ve grown pretty quickly too. How big are you now?” 

“‘I’m 6 foot 8!” Jenna said proudly, placing her hands on her hips heroically. Max smiled. 

“No I mean how big are you? Down there.” She pointed to Jenna’s crotch where sure enough a noticeable bulge was hiding amongst the folds of her toga. Jenna immediately blushed and looked away. 

“I….uh….I’m not sure? Pretty big. Bigger than my Dad at least.” She looked up at me hesitantly. I don’t know if I’ve just become more comfortable with this kinda thing over the past two weeks or what but I made a suggestion that I never would’ve thought I could.

“Why don’t we measure you? We have all the gear and I’m keeping track of Max already so we could just start including you.” 

“Are….are you sure that’s okay? I mean, you’re my brother?” Jenna seemed excited at the prospect but still weary. I shrugged nonchalantly and looked up at Max. 

“If it’s cool with you and Max, yeah why not?” Max nodded as well.

“Come to the basement, there’s a bit more space there than my bathroom.” She turned, still carrying me in her arms and Jenna followed. 

When we got to the basement Max brought us over to a measuring wall and stepped aside to let Jenna move forward. 

“We already know how tall you are but we might as well make it official.” Jenna stood with her back to the wall and looked up at Max. Max, instead of reading the measurement herself, handed me over to Jenna who held me in her arms like a mother holds her toddler. 

“Wow!” She remarked. “You’re so light Trev! It’s like holding a stuffed doll!” I smiled and looked over her shoulder.

“Yup. 6’8” even.” I confirmed. Jenna giggled and held me closer, placing her hand on the back of my head as she rocked back and forth. She stood like this for several moments, with Max presumably looking on. When she released me, her face flushed and hot, I saw that Max was indeed watching. She looked like she had just seen the world's cutest puppy howling for the first time. 

Next we moved on Jenna’s penis. She was a little nervous at first but once the toga was off and her cock started rising her nervousness was replaced with something else. Arousal probably. It was a bit impractical for me to measure her dick as it was well above my head while standing so instead Jenna kept me in her arms while Max knelt by her with the tape measure. She whistled loudly as she read out the number 

“16 inches, a foot and a half already! And you looked to be about 6 inches soft, you’re certainly no slouch!” She then reached one hand under Jenna’s cock to cup her balls. “And these things are easily grapefruit sized!” Jenna squealed lightly and bit her lower lip as Max fondled her balls. Max stood up and eyed Jenna from her lofty height. “If you keep growing like this I may have some competition.” Jenna recovered from her sexual haze and spoke in short breathy whispers. 

“Yeah well….I heard that….that the faster you grow initially….the harder it is to make it past the first week.” She was still holding me in her arms and had begun rubbing my back. I could feel her whole body shivering. 

“Where do you hear all this stuff?” I asked, hoping to distract her.

“The internet, there’s a bunch of forums for new futas that I follow.” I didn’t ask if she’d been following these threads since before she got infected or not. 

We moved on the scale. Max placed a hand in front of Jenna before she could step on. 

“You’re still carrying some extra weight there.” She pointed at me, still in Jenna’s tight embrace. “Why don’t we weigh him first then you can hold him while we do you.” Jenna nodded and gently let me down. I knew I’d shrunk a little further since yesterday. By my estimate I was around 3’2” now so it would be interesting to see what I weighed. The scale didn’t even seem to notice me. It was a heavy duty model, meant to withstand women Max’s size so it wasn’t all that surprising. Max placed one toe on the scale and it sprung to life. She winked at me as she removed her foot.           

“38 pounds.” I stated. It was kind of surreal, seeing such a small number associated with my weight. 

“My turn!” Jenna said and scooped me up into her arms once again. She skipped onto the scale. 

“241 pounds.” Max read out. “That makes you 203 on your own.” Jenna giggled. 

“It’s all gone to my T n’ A.” she bragged, cupping one of her large breasts in her hand. I hadn’t looked too closely at her chest before now but she certainly wasn’t lying. If her ass was big then her tits were equally impressive. Max chuckled and then pressed her chest together with her elbows. 

“I don’t know, you still look kinda scrawny to me!” She leaned forward placing her cleavage at Jenna’s eye level. The valley of titflesh was about as long as my entire body. Jenna must have noticed this as well as she lifted me up and placed me between Max’s boobs. My legs were swallowed by her breasts as she stood back up. She kept me steady with nothing but the pressure from her arms and the firmness of her tits. “Oh hello there~” She teased and puckered her lips as she raised her chest up to bring me closer. We kissed briefly and when we parted she was smiling again. The gloom she’d felt this morning after not growing at all was finally gone from her eyes. That was all I wanted. To see her eyes sparkle like twin stars when she looked into mine.
