I very much wish I grew up at a time where my phone could be used to record all the times I would listen to my parents having sex through the wall or on the other side of their closed door. Sometimes they would leave it ajar if it was late enough at night and they assumed I was long asleep. What they didn't know was that their squeaky bed would wake me up or I would be too excited to fall asleep in anticipation of hearing them so I could masturbate in time with my father's thrusting. If only smart phones were around in the late 80s and early 90s.
Now I'm the middle aged married man with children who creates the sex noises with my wife, recording many of them to listen back to during times I am alone and horny as well as sharing them with like minded folks here.
