For a monologue, what would be a creative way to portray a priest who lusts over a girl?

We have to write a monologue then present it in cl. I was igned to do Padre Salvi, from Jose Rizal's Noli me Tangere. He is a sickly priest who watches Maria Clara, a beautiful girl, take a bath. How can I portray him in the most creative way possible? Any thing is acceptable. Suggestions will be much appreciated!
