Website to upload audio files that can't be downloaded/expire

Hey everyone.

Is anyone aware of a hosting site where I can upload audio files, preferably wavs but mp3’s will do, where they cannot be downloaded/stored by the listener? The ability to have the files “expire” or self-delete after a set number of listens would also be really helpful. This would allow for better control of works in progress not ending up running freely around the web. I’m shy like that!
