I'm certain I saw this on YouTube once (although obviously not the full length video!).

It was of a 'schoolgirl' stepping in to a pool fully clothed, with a large rucksack on. She then started undressing in the pool, eventually getting down to her underwear before YouTube's rules meant whoever uploaded it cut it off.

If anybody recognises that and can find the YouTube video I'll be happy. If anybody can point me to the full video, I'll be even happier

Thanks.

Did you mean this one
