Don't tell Zack, but when his buddy Derrick was staying over he crept into his office to stroke his cock to some hardcore porn and made a mess all over his desk! It's something Zack has done plenty of times himself of course, but he would have loved to have been there to compete with his buddy in a cum squirting challenge. I think we all know who would win that, but the mess horny Derrick squirts out over the desk is still impressive - and has us all making a mess too!
