Sasuke, by a lot

As the towels come off, Naruko eagerly looks to her brother first and feels herself going wet with anticipation at what she sees. Naruto's is 10-inches long and roughly 3 inches around, though she's sucked enough cock to know it'll be at least a foot long when he gets hard. She then turns to Sasuke and her jaws drops as drool starts to form in her mouth. While Naruto's cock is above average, Sasuke manages to blow him out of the water with his cock being 16 inches long and 7 to 8 inches around. Naruto is similiarly gobsmacked to see exactly how outclassed he is while Sasuke just gives a smug grin. "Well it looks like we have a winner. " Naruko stated before smiling and taking a sultry tone. "Now how about claiming your prize."
