How about trying..

Dr Keller,

As you know I am working on a project involving the studies of lesbian relationships in 18th century Japan. I would love to include both the poetry of Hashi Hitmoi and some prints by various artist of the period but I am not able to locate this items except by going online and doing searches that will invariably lead to the viewing of many sites that go against State Law ***.**. By receiving your written permission I am aloud under the provisions of that law to view those sites on my office computer.

I have attached the appropriate paper work and would appreciate you help in completing it at your earliest convenience.

Thank you,
Me

Now since this person is your university supervisor and already presumably works in the same field as you, know the basics of what you are working on and likely has very similar beliefs on the topic (or you wouldn't be there). It should be no problem to get a timely approval.
