Run!

You cover your privates as best you can and run in the opposite direction, hoping whoever it is doesn't see you.

Your face feels hot, at first from the shame and embarrassment of the situation. But as you continue onward in this most natural state, your thoughts begin to shift, and the whole thing actually starts to feel kind of liberating.

The sun on your back, the air flowing over every inch of your body, and the feel of the grass and dirt under your feet (at least when you aren't stepping on a pebble or a prickly weed) all feels great, and soon you stop trying to cover up and simply accept this feeling of complete freedom.

Then the first tingles of arousal start to creep into your brain, both at the thought of doing something so naughty outside, and at the feeling of certain parts of your body that would normally remain concealed and restrained now jiggling and bouncing about for anyone see you.

You try to suppress your dirty thoughts and focus your mind elsewhere, when you notice something up ahead.
