Loved this site for ages, keep it up.
When I was a young teenager in Melbourne we had one of those metre deep corrugated aluminium sided pools with a blue plastic liner in. Being a bit older than the other kids I used to get time alone to play when the others were called in for baths etc. I found that if I dragged myself around by my hands with my arms straight and my legs out behind me, my nylon speedo's covered cock would slide along the plastic liner on the bottom of the pool, and it was a wonderfully teasing sensation as I would glide around for ages almost in a trance, and that gorgeous feeling increased until I thought I was going to burst, and then I'd shudder and fill the front of my speedo's with cum and collapse against the side of the pool panting.
Luckily we had an outdoor toilet at the back of the garage and I would disappear inside and rinse my bathers and marvel at the wonders of the world that was I growing into. I found out around the same time that the hose we left in the pool to keep it topped up could be used to great effect and felt nice if I directed a fine spray on the underside of my cock. I was mucking around with the hose one day though and slid it over my speedo's, big surprise when a stream of cold water shot up my bum, the hose wasn't on very hard, it must have just been the right angle I guess. It produced a nice erection, so back to the outside toilet I went, I don't often get the time or opportunity to indulge myself but I do love to feel the liquid slowly running into me and the lovely full feeling that an amount of warm water gives.
