New York Marathon
This event consists of ejaculation, twice in one session of masterbation. There are no breaks allowed and porn must be used to conquer this masterfull feat. It is named the New York Marathon because to accomplish this feat you need to have physical and mental endurance. Just like the Nike motto, JUST DO IT.
I got blue balled so bad that i had to do a New York Marathon to get all the cum out of me.
