The first time you came

Does a female's first orgasm count? If so, here's my tawdry little tale...

I was twelve, about three months from becoming a genuine certified teenager, when I had my first orgasm. I guess I should admit that voyeurism played a part, since I was spying on two other girls and the brother of one of them at "THE" moment.
My mother had asked me to go check on a neighbor's house that we were looking after while that family was out of town to attend a relative's wedding. I hopped on my bike and pedaled over, collected the mail, and decided to water some rose bushes and other stuff while I was there. I knew those folks kept their hoses and sprinklers in a shed in the back so I made my way around the side of the house to fetch what I needed.
When I entered the back yard I noticed that there were bicycles leaning against the back fence. I approached the shed quietly and as I got close I heard giggling. There was a small closet-like addition to the shed and I eased the door open, shut it behind me, and peered through a small opening in the wall that separated the closet from the rest of the shed.
To my amazement I saw the boy lying on the workbench, pants off, his stiff penis being stroked by the other girl while his sister played with his balls...WOW! His penis wasn't very big, now that I look back and having seen the "real thing"...an adult male's penis.
I can't remember if he actually came and if he did it was a subdued event, but after I'd tugged my shorts down and rubbed my clitty for maybe five minutes I surely did. It was both pleasurable beyond anything I'd ever experienced and a bit frightening too. Somehow I suppressed any little outcries and was able to make myself presentable and sneak out. My hand was soaked and I had to settle for an old rag to tidy up my pussy and thighs.
I came back later and watered the roses. The trio that has so entertained me was gone, of course, and I entered the shed, pulled down my shorts and panties, and was about to go for #2 but I was afraid someone might catch me at it. I settled for another try late that night, in the safety of my own bed.
