1. Masturbate, and cum into a sock. Save for later.
2. Masturbate again later into the same sock.
3. As you cum the second time, enjoy the refreshing coolness of your previous cum on your cock.
*Repeat steps 2 and 3 as many times as desired.
Thus is the Cool Cock Sock.
This move is useful for long porn-viewing sessions, when multiple masturbations are necessary.
Person 2: "Damn man, your cock must be sore!"
Person 1: "Nah man, I used a Cool Cock Sock, I feel great!"
