A Ghost hand
Your hand is asleep, but you’re still trying to jerk off. It feels like a stranger is doing it for you and judging your life choices.
I tried to finish my homework, but my hand was asleep and I was too tired to stop jerking off.
He said he was doing it for me, but I was just doing it for the vibes.
My hand was asleep, but my brain was alive and having a party.
