Oh man. I don’t think either of us were prepared for what today had in store. When I arrived to take Max’s measurements I initially thought that she must have grown nearly 4 inches in one day as her eyes were nearly level with my own. Turns out she was just wearing thick soled shoes. That wouldn’t be the only surprise in store for me today though. She was much more eager today and already had the measuring tape out and ready. As she stood against the wall she pulled me in so that our bodys were touching. Once again I was reminded of how much stronger she’d gotten in just a couple days. I could feel her breath on my neck as I looked for the measuring tape, she was clearly excited. I read out the measurement, 5’4”, two inches in one day. Max giggled with delight and planted a brief kiss on my lips before brushing past me and making her way to the bathroom scale. I turned slowly to get a good look at her.

Much like yesterday she seemed to have filled out. Gone was the petite stick figure of a girl, replaced by a blossoming young woman. Max let out a small “Ahem” and I realized she was waiting for me to come over and read out her weight. Apparently it was important that I be the one to do so. I hurried over and read out the number, 128 Lbs, She’d gained 13 pounds overnight. If this kept up she could outweigh me as early as tomorrow. 

“There’s one last thing before the good part.” Max whispered. She took my hands in hers and pressed them to her chest. “I went to get myself some new underwear today, guess how big?” Being at a loss for words was becoming a recurring theme with me. I hadn’t actually felt her breasts before today but I could tell she was much larger than when we started. 

“I-I dunno, D cup?” I managed to stammer out an answer. 

“Oooooh so close, 36DD.” Max trilled, stepping off the scale and closer towards me so that her enlarged bosom pressed against my chest. She was so close in fact that I could feel something else become enlarged against my leg. “We better hurry if we want to get measurement before I get fully hard.” Max giggled, stepping back and finally allowing me to breath. 

After taking a moment to collect myself I set about measuring Max’s penis. She barely managed to coax it down to a soft state after our little moment. I was shocked to find that while flaccid Max’s dick was larger than my own! It was an even 3 inches long, longer than mine by half an inch! Upon hearing this Max rapidly started to rise, clearly getting off on the idea of finally out matching me. Once she was rock hard I went back to get a second measurement. 7’5”, just one inch shy of my own erection. Max pouted slightly when she heard she wasn’t bigger than me but she quickly cheered up when I mentioned that by tomorrow she would easily eclipse me. 

Finally, we came to the arm wrestling match. I wasn’t sure what to expect. I won handily the day before, despite being caught off guard. But Max had been full of surprises today. As we sat down and gripped each other’s hands I noticed how much bigger She seemed over all. Just 3 inches in height and 24 Lbs made her seem like a completely different person. Her hands too felt massive compared to the first day. I then noticed her arms. She wasn’t quite what I would call “buff” but she was certainly well built for a girl, hell even for a boy her size. I was suddenly nervous about my chances. My apprehensions proved valid when we both started pulling. She was Strong! Not stronger than me yet, but boy she put up a fight. It was almost impossible to believe that just two days ago she couldn't even budge my arm. After a brief but intense battle I pushed her arm to the table and claimed victory, though probably for the last time. Max gave me a wink as she rubbed her bicep, then flexed for me. A pair of small, but defined bumps, rose on each arm. 

Oh man, I thought, I am in for it tomorrow!
