Ear Wank
When you’re jacking off in a house full of people, you get super sensitive ears so you can hear if someone is coming to bother you.
I was jacking off and my ears went into overdrive when my brother came in and I had to hide my phone behind my back.
I was jacking off and heard my dad’s footsteps from the hallway and I had to shut my laptop in a flash.
My ears were so tuned in during my jacking off session that I heard my sister’s whisper from the other room.
