The physical feeling (numb) associated with denying the passage of blood to both hands and ultimately losing feeling, followed by the act of masturbation.

Very similar to the stranger but with both hands.
Last week I was in a meeting so boring I sat on both hands and gave myself numbners, then felt sorry for myself I couldn't leave the room.

When you sit on your hand so long it goes numb and you jerk off with it so it feels like its not your hand.
Mark sits on his hand for over an hour while watching porn to really get the numbners going.
