Dean will fuck sampala and when Sam's reversed he'll make an excuse that it's technically the impala and NOT incest (Sam's tired of his shit)
Dean could not be blamed for this, he really couldn’t. It was no secret to Sam that Dean liked to have sex or jerk off in the Impala, hell Sammy was the college boy between them and Dean was pretty sure he had figured out years earlier that Dean sometimes got a little hot and heavy because of the car. So yeah, the point stands - Dean could not be blamed for this. Dean would have fucked his girl anyway, maybe rub himself against the sturdy leather of her back seat or maybe the steering wheel where the parts intersected and he could fit perfectly rub against the curved corner or maybe he’d kneel in the wheelwell again and -
Dean shook his head, trying to remember what he had been doing before he got distracted. Right, yeah, Sam being the Impala while Dean had opened the glove compartment just enough fuck inside, the soft plastic cradling his- and shit, he did it again.
He groaned loudly and threw his head back in frustration. Damnit, now he was definitely a little hard and Sam was still wearing that expression that said ‘I am pissed and disgusted but I won’t say anything and just be a little bitch’.
“Dean-” Sam finally said after another few minutes of awkward silence while Dean tried to think of anything but his Baby that sat in the unpaved parking lot out in front of the motel room.
“Shut up, it had nothing to do with you, Sam,” Dean immediately butted in.
“I didn’t even say anything y-,” Sam grumbled but got cut off again.
“It was just because of her, you know she gets me a little worked up, nothing to do with you,” Dean said and pushed away from the table they had just eaten their lunch at.
“Stop thinking so highly of yourself, dude, had nothing to do with you.” Dean just glared at him again before getting up. “I’m just gonna clean her, don’t know what residue you left behind.”
“Residue?” Sam spluttered, sounding indignant and Dean chuckled.
“Don’t forget to clean the glove compartment,” Sam yelled after him just before the door to the motel room fell closed, making Dean grumble.
