Just completed a 4 day camping/fishing trip and had the pleasure of sharing a dinghy (small tin boat) with 3 other guys who I only just know (my mate was in another boat).
Opposite me sat probably the fitter of the 3 boys I was sharing fishing space with and it became apparent pretty quickly that under his loose leg shorts he was wearing loose boxers - and by apparent I mean i was sitting opposite him and had an easy view (given his shorts had ridden up also) of his sack hanging lazily to one side of his shorts. If it had been a sunnier day I might have said anything, given they were open to rays of sunshine but with the low UV rating I simply enjoyed the view. I was hoping desperately to see more, waiting patiently for him to move around a bit so I could see up the other leg. Patience being a virtue I was happy to hold on to and was thoroughly rewarded for my efforts when he did move (albeit about 2 hours later) and I got the pleasure of seeing a juicy thick shaft and shiny cut head resting down the leg of his shorts. I didn't get too many peeks at this sight but enjoyed them while I did. Plenty of sack sightings though which I was just as grateful for...
