You leave the house together and start long boarding down the street. You're shoes and the glue are chaffing your feet but besides for that, you're a natural on the board. You intuitively know how to balance and lean to make the board obey your commands. Benji pushes his board faster and you move to match his speed down towards the park. Once you get there you spend a few hours practicing tricks, talking about different girls and their boobs, boasting about what you'd like to do to them if you had the chance. The day passes quickly and the conversations are easy. Despite this you can't get past the niggling feeling in the back of your head that something isn't right. Benji isn't your friend, he's your.... b, best friend? Late in the afternoon Benji announces that your heading back to his house for lunch and you obey. Isn't Benji great, he's always looking out for you.
You get back to Benji's place make some sandwiches and grab some chips before heading into his room. Benji's room is the coolest, he even has a laptop! Wait that's not Benji's laptop, its its, I can't remember. You eat your food in silence. Benji grabs the laptop, "wanna watch some porn?" He asks with a devilish grin. You nod your head, swallowing the last bit of sandwich.
He opens the screen, and there already some loaded up, two big boobed blondes are making out and feeling each other up. You watch intently, "whoa that's awesome" you stammer. You can feel your prick stiffen as you hit full mast. You look over and Benji has his hands in his pants stroking himself. He looks over at you before undoing the button of shorts, looking back at the screen, and pulling out his boner. You quickly follow his lead. You glance over at Benji's cock, it's about 4" long and has a marble size sack underneath it. Something is tellin you not to look, you shouldn't look at your brothers penis, but he's not your brother he's your best friend. You examine your piece, you're about 6" and have two grape size nuts in a generous sack. "I'm bigger" you say absent mindedly without even thinking of how Benji would take it. Benji turned beat red and said "it's not the size of the boat it's the motion of the ocean." You're confused, "you're a boat in the ocean?" You ask. At that moment Benji shot his small load all over his Lower abs, you finish a few moments after, turned on by the sight of your br..best friend finishing.
