How about a sort of a Groundhog Day file ...

If it is cloudy (no sun, no shadow) your cock is strongly, uncontrollably erect.
If it is sunny (shadows can be cast) your cock is 'scared', stays incredibly limp, and retreats wilted into your body.

I totally thought you meant the movie. Which would be an awesome experience.

Ive thought about the Groundhog Day as a trance for quite a while and would definetly like to experience some of this while under.
