Bush Bridge occurs when a woman's pubic hair creates a bulge in her bikini or underwear. The pubic hair acts as a support structure creating a gap between her skin and fabric of her panties or swimwear . The bush bridge can be difficult to distinguish from a standard fat upper pussy area (fupa) but the visible texture of pubic hair through the fabric is the tell tale sign that you're seeing a bush bridge. Only certain fabrics and fits will create conditions in which bush bridge can exist, making it relatively rare.
Hey Mikey, look at the size of her bush bridge! She clearly doesn't trim that thing!
