Naked in the garden

It's that time of year again, time for naked sunbathing in the garden!

Within an hour I caught my neighbour peering over the fence, which is odd as I know she's not 6'4" . Anyhow, she didn't move and the longer she watched, the more erect I got.

Here's the question... She was there for a good 10 mins, do you think she was having a play with herself? I'm also tempted to do the same for her but don't want to end up getting nicked!
