Exhibitionist Opportunity! Any Ideas?

I'm housesitting for family friends while they are in Italy for a month and a half. They share a garden with another friend of theirs that I have never met before (she's in her mid 50's) and I was told she would be coming by from time to time to tend to it. Three days ago I was sunbathing naked in the back yard and she stopped by to do garden stuff. I actually didnt notice her at all and only found out she was here when she walked right up to me and introduced herself. She was incredibly friendly and waved it off when I tried to apologize for being naked and then after a short conversation she said "It was nice meeting you... all of you!" then she went back to gardening.
She's coming back to work on the garden again today and it is the perfect opportunity for some exhibitionism. I'm going to read naked out on the patio where she has to walk by to get to the garden but that is all that I have planned so far.
Does anyone have any other exhibitionist ideas I could try to make the most of this opportunity!?
