The bigger, the better
But not obese girls

Girls with vulvas big enough that I can imagine they have really puffy lips that can hide a relatively smaller penis within their slits. Naked slits are good too, if you've got them.

I've got a handful to dump, but I'm hoping a specific image will show up here: She's sitting in a window sill with a skirt, legs toward the camera, calves higher up. She's got brown hair (short, I think), and her panties make a bulging mound between her thighs. It's an old favorite that I always have trouble hunting down whenever my collection gets wiped.

> tl;dr - please post the short-haired girl with the big vulva sitting in the window.
