's fault, who, on the occasion of Sam's birthday, (in)directly asked for it.
Why Sammy Is Hot
Sam Winchester is really hot for many reasons. One reason is his voice. Remember the classic dialogue "Bitch, Jerk"? Remember how he drew his voice up saying J..erk. That sort of intonation? Hot. Deep voice. Hot voice. Layered voice. Voice to hear panting above you sighing your name kind of voice.
Sam Winchester is really hot for many reasons. One reason is the way he smiles with dimples and eyes. That sort of sunshine spreading over a feline face and green sparkling in mirth and the way it makes you want to join in the happiness (and lick those dimples.)
Sam Winchester is really hot for many reasons. One reason is for being a giant freak. Well, freak is not really the word. Nor Sasquatch. Actually the word we are looking for is Apollo. Or hunk. Or posterchild for physical perfection. Or dream material. Or dreamboat. Those are the words we are looking for. Even when he's making himself unobtrusive, his hands are there. His muscles are there. His "whoa look it's not a skyscraper, it's Sam!" body is there.
Sam Winchester is really hot for many reasons. One reason is that he wears Evil well. It spreads through him and wears those muscles with pride. Moves them with purpose and weight. Brings forth animalistic movements, like a giant smooth feline through a jungle. And that deep throat laugh tied to a chair doesn't hurt either.
Sam Winchester is really hot for many reasons. One reason is that he wears Good well. As well as self flagelation. He carries the burden of the whole world on him, not realizing that Dean is right there with him. He tries to do what's right, tries to believe in something shinier, better, brighter...and is true to everything he wants to be. Even when he ends up crying. And boy, does that make us want to hug him more, or what?
Sam Winchester is really hot for many reasons. One reason is that he has more layers than people can see. Like, maybe he's the quiet college boy, trying to make it easier on everyone, but in bed? He ain't submissive, nuh-uh. He's got his own personal shadowed areas no one knows about, that makes the shiny of him even brighter.
Sam Winchester is really hot for many reasons. One reason is that he is part of the Winchester ka-tet, no matter how far. He took out two SWAT guys in seconds, in minimalist fluid moves. He would die for his brother. He loves his father. Misses his mother. Will always think of his loves. ESP? Sure. But he doesn't need that. Sam (and Dean Winchester) could move the world just by force of will-and heart.
There are many more reasons why Sam Winchester is so hot (like genes from the aforementioned Winchester gene pool). But these are the ones that I deem as the most important.
(I might have gotten a bit carried away.) But hey, happy birthday, Sam(my) even belated. :)
