Things had begun to get weird between the Winchester boys lately.

"Dean what's been with you man?" Sam asked with concern for his big brother.

Gripping tight to the steering wheel he tried to put on his best 'what ever do you mean' face as he glanced over at Sam.

"Whatcha mean Sammy?" he said as he turned back to the road and tried to focus on something else other than the intense pleasure coursing through his lower half at the moment.

There was no way in hell he was telling Sammy. Pursing his lips and pushing his hair to the side Sam stared at Dean. " I don't know Dean.. you just seem.. tense."

If that was a word for what Dean looked like nowadays. It happened randomly all the time now, Dean didn't realize that Sam had noticed but oh yeah Sam had noticed. It would be normal with Dean on the couch and then his breath would hitch and he'd hold his breath, white knuckling the cushions. He'd check to see if Sam saw and then hop up and excuse himself to the bathroom. With a forced chuckle Dean sped up trying his best to keep it together until they got to the motel.

" I dunno Sammy, end of the world'll do that to a guy"

Hesitantly Sam decided to leave it alone and watch the road because Dean was definitely speeding.

"What's the freakin rush Dean?"

" I. Need. To. Use. The. Bathroom." He ground out emphasizing each word.

"Dean what's-" "Shut up Sammy!, just don't ask!"

He knew he hurt Sams feelings but some things he needed to keep from his brother. Sam became very interested in the scenery and Dean didn't have to look to know he was sporting a Bitchface. The motel was up ahead and that didn't help relax anything. If anything it made the feelings worse. He had become better at lasting longer due to the frequency of this happening to him, which of course doesn't exactly make it better. It's just become quite the nuisance to out of the blue be forced into an orgasm.

His brow becoming sweaty as he tried his best to make it into the parking lot. Dean was near manic as he turned sharply into the parking lot. Putting his baby in park and then jumping out of the car and racing for their room.

Sam just sat outside dumbfounded. Did Dean just growl? He hadn't taken the keys or even bothered to close the door. "Somethin's not right" He said to himself. It was here in the car that Sam hatched a plan to see what was wrong with Dean. All he needed was his laptop and a certain download that was rather easy to get. Not wanting to go inside he hopped out, took Deans seat and decided to utilize the situation. Pulling out of the old motel parking lot and heading in search of some food.

Inside Dean was being overcome with pleasure seeming to spurt from all his limbs and run straight into his cock. " Oh god" he said gripping his aching dick. Shamelessly fondling himself through his jeans as he tried to get to the bathroom. "Fuck" he moaned out as he finally hit the bathroom door, Thankful for a door that locked him away from Sammy. He dashed across the small bathroom and turned on the shower as he continued to rub himself into oblivion. His jeans were too tight, everything was constricting him. He was burning up and he could feel his cock throbbing. His breath coming out in ragged moans. he began to remove his shirt. Exposing his well muscled abdomen now slick with a sheen of sweat. Tossing his shirt towards the sink he was so caught up in the ecstasy he didn't notice that the shirt was floating OVER the countertop before being quickly moved to the floor.

"oh god, uhhng" his breath hitched as a new wave of pleasure rushed over his body. Effectively weakening his knees and making his grip the wall in front of him. Legs shaking he attempted to unbutton his pants only to be hit with another unrelenting wave. "FUCK" he rasped out as he sat down on the toilet and fumbled with his zipper. Freeing his legs and taking the strain off his cock, He moaned lowly as the cold air hit his overheated body. His eyes rolling back as he freed his cock from the restraint of his boxers. Already slick with precum and harder than it was the last time he had an attack. Gripping himself tight he let his hand glide up and down his shaft, releasing moan after delicious moan as he tried to make himself cum. As turned on and ready as he was he should've came after first getting into the bathroom. He whimpered helplessly as he shamelessly pumped his cock harder and harder, His moans filled the tiny room along with the insistent smack of skin on skin. He was begging for it now, " Please" "oh god" "FUCK" Dean was basically fucking his hand now as he thrust upwards off his seat pleading between hitched breaths and moans. Then as if a grant of his request Dean felt himself about to release. Moaning louder at the approaching release he began to scream " oh god" " Oh yes. YES YES" His orgasm racking onto him as if every single pleasure receptor in his body had decided to have a party. His body hitching as he held his breath and came all over the wall in front of him, spurt after spurt of 100% Dean. His body finally able to come down He turned as he heard a slight noise but seeing nothing he lolled his head back against the wall completely spent. "fuck" he whispered under his breath as he bit his lip trying to get his breathing back to normal. "great, gotta clean up the mess now, Thanks." he said to no one as he wadded up the motel toilet paper to wipe the walls. Smirking to himself when he had to come back for more because there wasn't enough to clean the wall. When this was all done he stepped into the shower and relaxed as the water ran in rivulets down his sculpted body. Grabbing the shampoo and begginning to lather his scalp as he heard the front door to their room. Must be Sammy he thought to himself as he continued washing himself.

Sammy came into the room with a pizza and shakes to hear the shower running. "Perfect" he said with a smirk as he set his plan into the works.

I wonder what Sams Plan is? C: Review if you liked, this is my first supernatural fic.
