I had an idea I would like to see used for a story .... basically a father works nights so on his days off he lays in bed awake at night watching porn while his wife sleeps. He always turns down the volume on his phone so he doesn't wake her up but he didn't realize that his phone was automatically connecting to his daughters Bluetooth headphones (she paired them once so they could hear some music while walking and he never unpaired them) Anyway....her daughter puts on her headphones and hears someone listening to Daddy daughter porn and realizes her dad is watching these videos I the next room. From there yada yada yada they hook up.
