Lulu is a cute, lithe litte horse with a creamy white coat, and big, bright blue eyes. She, as does most horses, supports a long, bleach-blonde tail upon her hind end, though if she feels frightened, the small horse will sheild herself with it. It won't really do her much use, though it does make her feel safe, and that's all that matters.
She lives in the Evergreen Forest, her mother and father having been killed by monsters when she was a mere filly. She stayed in a bush until it got too small, and then she built herself a nest, just the right size for her to sleep in, with perhaps a bit of growing room.

The funny thing about Lulu, though, is that she can't remember how old she is. (You may decide her age.)

At some point, someone laid a curse upon her very being, causing her to sometimes lose control of herself when she's with another female, and as a result to her loss of control, her clit would turn into an actual horse-cock.
Lulu sometimes dreams about making the other females she meets pregnant, or being impregnated herself by a herm... She has a special liking for herms...
