Wearing a sleeveless white t-shirt, and grey trousers designed to cling nice and tight, he gets a thorough hose down from an off screen companion. Soon the garments are absolutely saturated and are clinging to his body.
Needless to say, the top becomes see-through too and we see his proud nipples standing out.
His face, hair, torso, crotch and legs... they all get a prolonged soaking. Eventually he decides to remove his soaked top, trousers and pants.
When the hose stops briefly he thinks he has had a reprieve... but then a bucket of water is poured over him from above. Then the white briefs get a thorough soaking from the hose... and still his shower continues.
Then Will gets the shampoo / shower gel and shampoos his hair and soaps up his body, before the hose washes him clean.
Finally after a long showering, Will's drenching is finally over.
