Sarina Namiki - We Can Measure How Tiny Your Mouth Is With My Cock

I was the only one from my class who hadn't had a growth spurt in ... well, any part of my body. I was so worried! It wasn't just my height. My boobs were not as big as they should be, my legs were the shortest, and even my pussy was tiny. I kept measuring myself every day, but nothing was changing. That's when my stepdad suggested another way to measure things. He said I could measure my mouth with his cock. Turns out that my mouth got way bigger when his fat dick was inside! When he said he could also measure and stretch my vagina the same way, I couldn't wait.
