I'm 18.. This is what I discovered while on vacation.
I found out the joys that a hot tub can bring when we were on vacation and my whole family had been in the hot tub but they decided they were done. I decided to stay a little longer. I naturally started messing around... and one thing led to another and I was erect and horny.
I had used a showerhead before on my manhood but never anything as strong as a hot tub jet. I decided to give it a try.
WOW! It was intense. Way too intense actually. I didn't realize how strong it was and put my manhood way to close. As soon as I figured out the optimal distance I was in heaven. I probably came in less than a minute.
Since then I have used every opportunity I can to use hot tub jets to masturbate with. I've also used pool jets in a pool late at night! With people in it! I just go up against the side and act like I'm relaxing.
I love the feeling it makes and to this day I've never had a more intense orgasm! (And I've tried many many things.)
It's just my luck that my parents are buying a new hot tub next week... I can't wait to try it out.
