SD Boy, being filmed in San Diego, features a lot of hot military studs because of the proximity of the Marine and Naval bases close by. Their latest video featuring two real life Marine brothers jerking off is so fucking hot, you will be grabbing your cock and pumping one out before you know it. Preston Phillips and Justin Phillips, known in their Marine barracks as the Preston Bros, are more than just brothers, they are best friends. There is only one year in between the two brothers and they have done everything together their whole life, including joining the Marines. When one of them thought it would be fun to do a jerk off video to earn some extra cash, the other one wanted to do it as well. Justin and Preston are not shy in front of each other. They have had many threesomes together so they are completely comfortable jerking off and playing with their big Marine cocks in front of each other. They start their jerkoff video when the cameraman puts in some straight porn for them to watch. The brothers take off their clothes and sit on the couch and start working on their cocks. They comment to each other about the girls in the video playing and their jerk off techniques. When they are both fully erect, they compare their cocks to see whose is bigger. They are both about the same size, but Justin's cock is a little wider. They both put some lube on their cocks and begin stroking harder and harder. They make a bet that the first person to shoot first has to buy the beer later. They both continue to stroke faster and faster. Justin shoots his load first, and his cum shots go all the way to his neck and cover his chest. Preston follows shortly after squirting thick chunks of cum all over his stomach. Both of these Marine studs are hot and it's even hotter watching them knowing they are real Marine brothers! Don't miss them.
