Ear wanking
When a kid is wanking ears, they’re so focused on not getting caught they can hear the smallest noise, like the fridge humming or their little brother’s sneaker squeaking. It’s like they’re on high alert, waiting for their doom.
I was wanking ears so hard I heard my little brother’s sneaker squeak from the other side of the house.
My friend was wanking ears and got caught because he heard the door creak. He was so embarrassed.
I was wanking ears and heard my mom’s footsteps in the hallway. I had to zip up my pants before she came in.
