By default you can't. However, Azure websites now support running on a Virtual Network, so (in theory) you should be able to create a vnet and place both your SQL Server vm and the Azure Website on that vnet. That should enable you to connect to the db using the internal (vnet) ip address of the vm. I haven't tried this tho, so no guarantees.
