I'm very quiet, but my sister is the wild one. She's the life of the party. Lately when my parents go on trips she's been bringing her bf over. They're usually respectful and aren't PDA, but he usually stays the night. My room is right next to hers. At night I can hear everything. My sister tries to be quiet but I can her her and her bf grunts and when she's having an orgasm she just let it out. I used to get annoyed and would put my headphones on and try to forget about it.

The last time it happened though, I'm not sure what got into me but I had to keep hearing it. Like I had my ear to the wall and kept listening. He has sex for so long and I was even touching myself to it. I don't know what's wrong with me but I hope I get to hear them again..
