Listening To My Upstairs Neighbor

This happened just this past Tuesday morning. I was awoken by the sound of the woman that lives above me having phone sex with her boyfriend. My girlfriend and I have heard her having sex before, in the bedroom, in the shower, in the hallway and my girlfriend thought she heard her masturbating months ago but that morning was the first time I had heard it for sure. The sound that I heard that woke me were these short but loud

'OH!'

'OH!'

'OH!'

'OH!'

'YEAHHHH'

In between the passionate moans I could heard what sounded like one of the rabbit-type vibrators, the ones with the plastics beads that move around the base. The vibration noise would get loud then soft then loud again over and over, so I can only assume that it was going in and out of her vagina. At this point I'm wide awake with my heart beating out of my chest, completely turned on by what I heard. I had just heard my very attraction neighbor make herself come! Needless to say, I'm dying to hear it again and it has becoming something I think about while masturbating.
