I have a crazy fantasy: You have a hole in your jeans ass and your buddy's hand is dripping with slime in your hole and you enjoy it very much. Your cock spits explosively in your tight jeans
his shoes are great; the look like they keep water inside for a long time; get wet in the morning and still squelch in the evening, what's not to like?
This is better than washing the car. The strong water jet is better than jerking off and will quickly make you cum in your jeans. I have experience with this
