I am not sure whether I already contributed something about my very first listening event but is was definitely an exciting and intoxicating adventure. I was in my early years of my studies, probably 3-4th semester when I discovered a student girl in my dorm masturbating by rubbing her body on her blanket when she was lying on her stomach and watching TV. It was actually pure random that I noticed this when I was looking outside in the evening through the window of my student dorm and she had switched on the lights but obviously forgot to close the curtains, so one could see things quite clearly, but she was very silent (and the TV was running).
I described some more details already here:

Her masturbation session excited my interest a lot and I thought she will probably repeat it in the evenings of the following weekend, but this did not happen because her boyfriend gave her a visit over the weekend. I then came to the idea if she has her boyfriend visiting they will likely have sex, so I was lurking around from time to time following whats going on. At that time I was not aware whether one could listen something at all through the doors. When they went to bed on a Saturday evening between 10 and 11 pm, I became aware of some cuddling sounds, kisses and at a certain point in time I also identified something that sounded like he was removing her slip from her body. Few moments later I experienced my first listening event, very loud, very intensive and emotional, and with orgasms during sex for both of them (which did not happen later again, if you remember the Nina series)... I was really exited about this event and nearly became addicted to this kind of actions. Unfortunately it really took some time and several of those events (also from other students) until I came to the idea to try to record these adventures to keep them for later. This is the very first origin of the files I posted here collected in student dorms...
