Watching My Sister Vibrate Her Clit

My sister used to listen to music with headphones quite often. She is three years older than me.

Whenever my parents were out for the night she would listen and also use my parents massager on her pussy at the same time right through her PJ's while I was there. Being young I had no idea what she was doing nor why she would make such funny faces like she was in pain.

A few years later I figured it out when I too tried the massager on my penis. By that time I was right into my cock and ejaculating as much as I could. WOW what a great feeling this little machine would give. I would sneak it away every chance I got and it would give me an orgasm within about 30 seconds.

I'm sure my sister had about 500 orgasms over the time we were home alone. She would vibrate her clit for about an hour each time then stop just before my parents came home.
