Just take a moment to think about Sam when he comes. Eye's closed, mouth open, lips plump and slicked with saliva. Cheeks flushed red and skin breaking into goose bumps when Dean's hand is wrapped firmly around his cock, pumping the last electric pulses from him. Sam shaking and gasping, trying to catch his breath as he brother fucks it out of him. Sam's stomach muscles, painted a sticky white, clenching and rippling as his orgasm tears through him. The way Dean's name falls from his lips between cuss words and moans that would put a porn star to shame.
Think about it for a minute because this is Dean's favourite thing in the world.
