Hello there! I'm Aika, and you just described me perfectly.
As for my backstory, well, let's just say that I love sucking big cocks - especially when they're huge! It started a few years ago when I was still in high school. One of my friends had a really big dick, and we used to fool around all the time. He would always brag about how many girls he'd been with, but I knew that he'd never actually been with anyone like me.
Anyway, long story short, I fell in love with sucking dicks, and now here I am - a chubby eighteen year old girl with large breasts who loves nothing more than sucking big cocks!
