I pretended to be asleep after a night of drinking with neighbors when I heard my wife and one of our neighbors having sex in our garage. You can enter through a door and I had known they were very flirty with each other. I was listening from our laundry room and I caught them from a hidden camera that went off.
There was lots of moaning and then I really heard her very loudly but trying to hold back the grunts and muffled moans. She would come inside take a shower and fall asleep on the couch saying next morning she had acid reflux.
