"Hh... hh-h... hhHHHH..."
Dean cocks his head, shakes it and lets out a breath. He sniffles and then shrugs at Sam, half-apologetically. "So buch for that."
Sam slides a hand into his pocket and adjusts himself. "Hmmh." On the hood of the car he angles himself toward Dean until their knees are touching. He pulls out a tissue, drops his chin to his hand and waits.
Dean shields his eyes and glances up at him. "Wh... h-HH... hah-hhHHH... agh." He rubs his flushed nose and presses a knuckle into it. "Hrgh."
Sam squirms. A breeze scratches fallen leaves across the pavement, soothes his overheated face. "Can I...?"
Dean shivers, one hand hovering by his flaring nostrils. "Hh-hhg... HH-hhhhh." Squinty eyes take in Sam's face. "Yeah."
Sam smiles a tiny smile. He shifts so their hips are touching, then dips his face close to Dean's red nose and presses a soft kiss to it.
"HH-HHH-HH..." Sam leans back to observe. "Haggh. H-HHk... hhH-H... ugh." Dean pinches his nose, grinds his nostrils together and watches an eighteen wheeler roll past.
"Hey." Sam palms Dean's chilly hand. "Gently, man." He inhales the smell of distant woodsmoke and flutters his lips over the warm bridge of Dean's nose, the hollow of his eye, the curve of his nostril. All the while, his fingertip's ghosting over the rough rim of Dean's other nostril.
Dean's breath catches and Sam swallows. "Hhhh-hhh-HHH-HHHHH..." His eyebrows crumple, his nose wrinkling, chest heaving. Apple-red lips part wide. Sam remembers the tissue just in time.
"Hhh-HASHSZSHHZSHUH!"
