so embarassing

I'm a 17 year old girl with blonde hair, 5'6, 117 pounds and always horny. So the other night my parents and little sister were home and I was laying on the floor of my bedroom rubbing my clit getting wetter and wetter. Then, I took 2 of my fingers and started rubbing it faster, up and down and side to side. I knew I was going to orgasm soon, and when I orgasm, I always moan, I can't help it. So my little sister does karoke and has this wireless microphone. She had left it on and it was on the chair next to where I was lying. I felt the orgasm coming on, and then I had it. I began to moan feeling my cum leak out. What I didn't realize was that the microphone was sending my moans loudly from my room to the karoke thing downstairs. My little sister later told me that everyone in the house heard.
