I apologize for leaving you guys hanging for a whole week. School's a bitch. But thankfully I have two more weeks left.

Just to let you know the line where Dean says "I love it when they clean up after themselves" is a line I took from a Charmed episode so unfortunately that is the whole line I don't own in this whole story.

Enjoy and please review. Tell me what you like, don't like and anything in between.

Chapter 15

Sam realized that he was getting weaker by the minute. He thought he would just lie on the bed and take a nap, but he could barely move. It was as if all his energy was depleted. What is wrong with me? It hurts to move. Sam decided to try and stand and slowly walk to the bed. As he tried to stand, the chair fell from behind him and he felt his legs give out. He tried to catch himself by gripping the table but his arms didn't seem to work right and he ended slipping and fell on the floor.

Dean bolted awake at the noise, "Sammy?"

Sam was sitting on the floor looking stunned. Seriously, what the hell is wrong with me? I feel so entirely weak.

"Sammy, you okay? What happened?"

"I-I don't know. I was t-trying to walk to the bed because I felt weak b-but I fell."

"You want some help?"

Sam nodded and Dean walked over and attempted to help Sam to his feet but Sam wasn't budging.

"Sammy, you're gonna have to help me a little."

"I can't. I can't seem to move my body. I am so weak."

What the hell? "What do you mean?"

"I-I-I can't seem to m-m-move. I f-feel like I have no energy," Sam said weakly.

"Alright Sasquatch, I'm gonna lift you. You ready?" Dean asked as he placed a hand underneath Sam's legs and another around his back.

Sam nodded and Dean lifted him and placed Sam on the bed. Sam arched into Dean so that his chest was rubbing against Dean's.

"Sammy, stop."

Sam shook his head, "Can't. Need you, Dean. I need to fuck you so bad," he said lifting his hips trying to rub his cock against Dean's.

Dean moaned as Sam's cock touched his, "Sammy, baby, come on. We can't do this. Not with how weak you are. You just need rest."

Sam shook his head again, "Don't need rest. Need to fuck. Need it like my life depended on it," he teased.

"Dude, you are too weak. There is no way you can fuck anything."

"So fuck me. Please, Dean. I need it," Sam whined.

Dean sighed. He needed Sam to rest so they can try and figure out how to destroy this Wanyudo and then deal with Damien.

"Baby, we can't. Just try to rest."

Sam shook his head and tried to arch his back to Dean's body, but couldn't so he settled for running his hand on Dean's cock. Dean hissed.

"Don't…don't understand, but…" Sam panted.

"…But what?"

"I need it. Please?"

Dean sighed but eventually nodded, "Okay."

Dean made quick work ridding Sam of his clothes and then took his sweet time removing his own clothing. After tossing the last bit of his clothing off, he lay on top of Sam and grinded his hips against his. Sam moaned and tried to wrap his legs around Dean's waist. He whimpered when he couldn't so Dean helped.

"Better?" he asked as he grinded his hips again.

Sam nodded. Sam tried to match Dean's thrusts but couldn't really do it and whined.

"Relax, baby, let me take care of everything," Dean soothed.

Sam nodded as Dean kissed him. After a few minutes, Dean stopped grinding his hips and moved Sam's legs from around his waist. He laid Sam's legs back down on the bed and moved down to take Sam in his mouth, but Sam gripped his hair and stopped him.

"What's wrong, Sammy?"

Sam shook his head, "Enough foreplay. Need you inside now."

Dean smirked and continued to move down on Sam bypassing his aching, seeping cock and stopped at the entrance to his entrance. Gripping Sam's legs and spreading them wider, Dean moved in between and thrust his tongue inside Sam's entrance causing Sam to involuntarily buck and moan.

"Fuck, Dean!"

Dean continued to thrust and penetrate Sam with his tongue for a few minutes. After a few minutes, Dean stopped and reached for the lube. Slicking up two of his fingers, he thrust them inside scissoring and aiming for Sam's prostate.

"Shit! Dean, come on," Sam begged as he bucked.

Dean removed his fingers and slicked up his aching cock and slipped easily inside. Sam winced at the force of it and Dean sat still.

"You okay, baby boy?"

"Yeah, just fucking move already."

Dean obliged and moved slowly aiming for Sam's prostate again.

"Oh, God! Fuck, faster, Dean."

Dean picked up the speed and was surprised when Sam started matching his thrusts.

"Fuck, Dean, go faster and harder," Sam panted.

Dean shook his head as he gripped Sam's hips and thrust, "Not trying to hurt you," he panted.

"Go. Faster." Sam growled.

Dean sighed and increased the speed again. He thrust hard into him that the bed slammed against the wall. Dean reached in between them and gripped Sam's seeping cock and began to jerk it in time to his thrusts.

"Oh, God! Dean… gonna…come."

"Yeah?" Dean panted

Sam moaned.

"Come hard for me, baby. I wanna hear you scream."

Dean thrust hard into Sam and he felt Sam tense. Sam soon came hard screaming Dean's name and spilling all over their chests. Dean thrust into Sam once more before he came moaning Sam's name.

"Feel better?" Dean panted slowly pulling out of Sam.

Sam nodded moaning at the loss. Dean chuckled and pulled Sam closer.

"Rest, baby."

Sam let his eyes droop shut and soon he was sleep. Dean smiled at his brother and let his mind wander. He wanted to know why Sam was so weak earlier. He noticed that sometime during sex, Sam seemed stronger. Could it be the sex? Could sex have something to do with why Sam is the way he is? Dean wondered. He shook his head and drifted off to sleep.

Sam woke the next morning feeling stronger. He opened his eyes and realized that he was alone in the bed. Jackknifing to a sitting position he wondered where Dean was. Just then he heard the shower and calmed down. Dean emerged outta the bathroom several minutes later.

"Morning, Sammy."

"Morning, Dean," Sam replied and swung himself over the side of the bed.

"Whoa, take it easy, Sammy."

"I'm fine, Dean."

"You sure?"

Sam nodded, "Yeah, I'm gonna take a shower."

Dean nodded, "Okay. I'm gonna run to the diner and get some breakfast."

Sam waved as he went into the bathroom. In the shower, Sam let his mind wander about yesterday. I don't get it, why was I so weak? I mean I understand that I was weak from the demon attack, but I shouldn't have been that weak. What the hell is happening to me? And how come I feel better after having sex? Maybe Dean was right, I'm a sex junkie.

Sam shut of the shower and toweled off and wrapped the towel around his waist and exited the bathroom to find Dean sitting on the edge of the bed on the phone. He quickly got dressed and went to sit next to Dean just as he hung up the phone.

"Who was that?"

"Bobby. We were talking about the Wanyudo. He said the only time that we'd be able to see the thing is sunset. Right before the sky get's dark."

"Great, so what do we do in the meantime?"

"Eat."

Sam grinned and followed Dean to the table.

"Sammy, you sure you're okay? I mean you seemed pretty weak last night."

Sam nodded, "I'm fine, Dean. I don't know what happened."

Dean shrugged, "I think I'm beginning to understand."

"What, that I'm addicted to sex?"

Dean laughed, "No, although I know you're addicted to sex, but that's not what's going on."

"Then what, Dean? I'm worried."

"Yesterday, when we were attacked by those demons. You used a lot of your power which sapped your energy. Thus this left you so weak. This wasn't the first time you used your powers and got weak. What I am guessing is that the more you use your powers you become weak, and sex seems to replenish that energy. Although I don't understand how because it usually saps a person's energy."

"So basically, I need sex to replenish my energy?"

Dean nodded.

"When did you get so smart?" Sam teased.

"Hey, I didn't get my GED for nothing," Dean smiled.

After they finished eating, Sam discarded their containers and climbed back on Dean's lap.

"So we have a whole day to kill. Whaddaya want to do?"

Dean shrugged, "I don't know, but I do know that we need to get the supplies we need to kill this Wanyudo."

Sam nodded, "Right, all we have the holy water. We need a stake and a bucket of acid."

"So let's get going."

Sam pouted, "You wanna go now?"

"Yeah, why, you have something better in mind?"

Sam arched his eyebrow, "Hell, yeah," he said and kissed Dean deeply.

"Dean, look out!" Sam screamed from across the park.

"What, it's just a freaking wheel. It can't hurt me."

Just then the Wanyudo shot fire out of his mouth that Dean dodged at the last minute.

"Right, it can't hurt you," Sam growled.

"What the hell are we supposed to do if we can't get near it?"

"Stop it."

"No shit, Sherlock. How?"

"No, Dean. Stop it. Use your powers," Sam said and breaking out into a run as the Wanyudo headed his way.

Dean followed and put out his hand to telekinetically stop the Wanyudo. The Wanyudo stopped in mid-roll. Sam threw his stake at the creature piercing it right into the mouth. Dean continued using his powers and poured the acid/holy water mix on the creature and then let go. The Wanyudo sizzled and burst into flames and then disappeared.

"Love it when they clean up after themselves," Dean smirked.

Sam laughed and ran towards Dean.

"You okay, Sammy?"

Sam nodded.

"Good, let's get outta here."
