Sam knew how to deal with is father. Or at least that's what he told himself. He could deal with the lingering looks, and the subtle touches. He could even deal with the sick games, or as his father said "training". Dean didn't know his younger brothers training was different, that instead of makeshift shooting ranges it was see how long he could handle standing outside in the cold, naked, before he broke and begged to come inside. Sometimes John would refuse him when he begged, but when he didn't it was almost worse.
"You're not going to get warm unless you sleep in my bed tonight, son" His father would say.
"It's okay."
"That was an order, Sam."
Sometimes Sam wouldn't be allowed to put his clothes back on and the only way he could get warm was to snuggle closer to his father. Then John would drape his hand over Sam's small, shivering, bare, body and pretend this wasn't at all what he planned, and that he didn't enjoy every second of it.
Sam only pretended he knew how to deal with his father, and pretending wasn't going to work for much longer.
Sorry this is short. It's only part 1 of chapter one, and is really more like a glorified summary. I'll have part 2 of chapter one posted later tonight (probably).
