Shower Head

In the shower, if I decide to masturbate, before I even touch my penis I love to get the shower head, turn it onto a lukewarm setting and very slowly move the jet from my anus up towards my balls. I hold my balls up a little when I do this, to expose the perineum. As I move it over my perineum the feeling is overwhelming. I then carry on over my balls and right up to my glans. I then go back to my perineum/balls area and move the shower head up and down and in circles. It's sensational. As I'm doing this I begin to wank with my other hand, very slowly. As I'm so turned on by this point I feel my orgasm approaching very quickly. I try not to go too fast as I reach climax, to really stretch it out.
