Dean smirked right back at him and nudged him with his knee, deciding he really liked Sam like this. He was bossy on the best of days, they both told each other what to do, snapped and argued and were generally bullies to each other like brothers were supposed to be, but that tone definitely did things to him.
"You wouldn't dare," he hummed out, scraping his fingertips against Sam's shoulder. "Bitch." He had to add it, even if it had been years since they'd had that exchange. A low groan came from his throat as Sam took him in like that and then, god damn, that hand on his leg. He sank back, one hand dragging through his own hair, and he tried to keep his hips still.
