My First Time on a Family Vacation

It began in the summer when I was 14 and like other years my parents, my younger brother and myself would embark on a summer vacation to usually the east coast shore line somewhere.
This years trip was no different and it would take us around 12 hours by car to get to our destination to a new beach resort in a popular tourist area.
Our first full day there we were tired of driving and decided to spend the day at the beach and around the pool area so most the day was spent with the parents sitting in lounges while my brother and I played in the pool or the ocean. It was decided that late afternoon we would take turns returning to the room to shower and get dressed to go out to eat that evening.
When it was my turn to get cleaned up I went up with mom and did just that. Once I was in the shower my attention quickly was drawn to the shower head that I noticed was on a hose and soon realized it was a hand held shower massage device that I'd never seen before.
It wasn't long after playing with the different settings I found the one I liked best and continued washing my hair and rinsing off with this modern marvel until I was about finished and then totally by accident pointed it between my legs, instantly I felt a rush charge through my entire body.
At 14 my sexual experience was little more than touching myself a few times but never really seen the attraction even though I had probably had heard of masturbation by then I thought it was something guys did but certainly not good girls.
After feeling the first rush I really wasn't sure what I just felt and had to do it again...and then again..and again...until finally I left it pointed up between my legs.
I remember holding the shower between my legs with one hand and with the other hand holding on to a towel bar while the sensations got stronger and stronger and then feeling as if I needed to pee until I was having a full blown orgasm (my first). My knees were buckling, my hands were shaking as I tried my best to continue standing as well as keeping quiet.
And just as it all subsided I heard a knock on the door and my moms voice asking if I was OK and that she still needed to get in there.
I quickly hung up my new friend, toweled off and left the bathroom with probably a dead giveaway look on my face.
That evening we were all sitting at the restaurant and talking about what we liked best so far about this resort and after the others contributed my mom (looking straight at me) says how she loves the shower massage. I think I passed my coke through my nose and turned beet red.
