"Awesome," he answered back, glad Sam had enjoyed it. He'd always presumed Sam was the quiet stoic type who would fuck you within an inch of your life. He'd always felt a little bad for the girls that Sam slept with, because he'd seen his brother naked before and, well, damn. Now he understood the fire Sam had in him at these kinds of times. It was definitely a turn on.
Looking at the mark, Dean chuckled a bit. "Don't worry about it. You've bitten me plenty of times, dude." He'd dealt with Sam's biting stage as a child. He'd only been six when Sam started that, but he got bitten more than their dad did, because he was always holding onto Sam. "Besides, this time was kinda hot."
He nodded, finally stepping back into the water and rolling his shoulders, not willing to admit he was a bit dizzy, instead just scrubbing at his skin. "I'm fine, I'll just sleep late tomorrow."
