I'm a 22 year old woman in my third year university and I get turned on listening to my roomate (male) fuck his girlfriend. They do it often and the walls don't absorb any of the sound. It's like if I'm in the room next to them.

I like to pull down my panties and masturbate while listening to both of them. I get turned on when she is over and wait anxiously for them to brush their teeth and head to bed.
