So i caught my housemate and her bf doing the dirty.

Went back home and heard noises upstairs, i already have a feeling they're doing it but it was so loud i could hear it from the stairs. When i reach her room i could hear both of them moaning and grunting and pounding, i am already attracted to them both secretly but hearing this turned me on even more.

I was pratically behind the bedroom door listening for a whole 20 minutes while my panties are wet, and then when they stop i quickly ran to my room as i was scared if they open the door. I remember masturbating and orgasm like twice that night fantasising walking into them and joining them.
