Emika is my best friend's younger sister, and I've known her since we were kids. But the Emika I met today after a long time wasn't the one I remembered. She seems to have grown quite a bit while I was away. She's now taller than me, and she's started wearing short skirts that end above the knee. Just a little movement and her panties are about to be seen... Whoa, I saw them just now... Light blue striped panties. There they are again! They have a little ribbon on them, so cute... The plump flesh of her pussy is just irresistible... Wait, is she purposely showing me her panties? Did she notice that I was peeking and breathing heavily in excitement? "You're getting horny just by looking at a younger girl's panties, huh~" She teases me with a smirk, and though it's pathetic, I just can't stop jerking off! I want to have some panty-sex with Emika-chan so much more!
