Chapter 3

Dean leant back against the wall, closing his eyes as the bathroom steamed up so much he could barely see. He heard the shower turn off and opened his eyes only to jump at finding Sam right in front of him. He gasped, heart racing from the shock and Sam cocked his head to one side, staring down at him.

"Make some noise Sammy." Dean grumbled and Sam knelt.
"Sam?" Dean called, getting a little nervous. He stared at Sam's wet, naked body, taking in all the familiar scars in the paler skin and tried to fight down the flash of lust at the sight. Sam sniffed the air and Dean squirmed, knowing Sam had smelt that. He was getting scared, why wasn't Sam answering him? Sam leant forward, nuzzling his thigh and Dean gasped, eyes wide.
"Sammy say something!" Dean demanded, voice rising in pitch slightly. Sam kept nuzzling at him, moving up to nuzzle Dean's throat, his hands pinning Dean down by his thighs. When Sam licked the vein Dean's heart rate skyrocketed. Dean was about to yell for Bobby when Sam's mouth sealed over his, his tongue flicking out to trace Dean's lips. When Dean gasped again Sam's tongue slipped into his mouth to start mapping it before tangling with Dean's, coaxing Dean into responding. Sam moved, straddling Dean's waist without breaking the kiss and Dean's hands moved to wrap around the wet body. Dean pulled back, panting for air and Sam let him, running his hands over Dean's clothed body.
"Sam please, talk to me. What…."

"Dean." Sam whispered before claiming his mouth again. He slipped cold hands under Dean's shirt, feeling the goosebumps form at his touch even as Dean moaned. Sam could smell the lust, arousal and confusion wafting off of Dean and it was driving him crazy. He wanted Dean, wanted him to be his and he could feel that Dean wanted him too. His hands went to Dean's jeans, palming the obvious tent in the material and Dean bucked up in reaction. Sam went to open Dean's belt but then Dean's hands were grabbing at his even as Dean forced his head away.

"Sam stop!" He almost yelled and Sam paused, confused. Dean relaxed a bit when Sam stopped, he didn't want to have to yell and then have Bobby barge in and see them like that.
"Sam calm down, what's going on in that head of yours?" Dean panted and Sam smiled at him, thankfully without his vampiric teeth showing.

"You want me, can smell it. Please Dean." Sam murmured and Dean swallowed.

"Sammy…..you're my brother." Dean argued weakly and Sam just looked at him.

"Vampire." Sam argued back, leaning in to suck at Dean's throat again. Dena started to give in only to jump as the door was banged on.

"You staying in there forever?" Bobby called through it and Dean went bright red.

"Come on Sam, Bobby's waiting and I need dinner." Dean told him and Sam sighed but got off him, kissing him softly. Sam grabbed his clothes and started getting dressed while Dean focused on tyring to calm his body down. They left the bathroom and Sam walked over to the window to peer out, smiling at the lack of sunlight. Dean sat at the table and grabbed a sandwich out of the bag of food they'd gotten while trying to figure out where Sam was. It wasn't the freshest but it was food. Once he was done eating Sam walked over and dropped onto his lap, cuddling in and Dean could feel Bobby staring at them.
"Sam…."

"You ate." Sam answered, kissing Dean's throat.

"What the hell?" Bobby demanded and Sam looked over at him.

"What?" Sam asked in confusion and it hit Dean that Sam may still be Sammy in some ways but he was also a vampire now. Sam went back to kissing and licking him and Dean fought not to moan.

"Sammy stop, we can't." Dean gasped out and Sam leant back, frowning.

"Why not?"

"Sam think really hard okay? Come on kiddo, think human not vampire." Dean urged and Sam's frown deepened as he tried to figure out why Dean was denying what they both wanted.

"Don't understand." Sam mumbled, hiding his face in Dean's chest and Dean hugged him, rubbing Sam's back.

"It's okay Sammy, I know." Dean whispered, looking at Bobby with pained eyes. Bobby nodded sadly; he'd been expecting it unlike Dean who'd thought Sam hadn't changed at all other than being overprotective to the extreme. Vampires didn't think or see things the same way as humans did. Seeing the way Sam was clinging to Dean it made sense Sam had always loved his brother but for a vampire that love wouldn't have the same boundaries and a vampire would see nothing wrong with having sex in front of its nest.

"Sam Dean is your brother, you know that right?" Bobby asked gently and Sam looked over at him, nodding slowly.
"Brothers don't…..they love each other but not like that. And you don't try to have sex with other people in the room." Bobby explained and Sam frowned in confusion. It seemed the more time that passed the more of Sam's human understanding slipped away. Dean sighed and pulled Sam close, petting his hair and Sam purred.

"It's okay Sam, I know its confusing kiddo but we're human remember." Dean told him and Sam nodded.

"Want you." Sam whispered and Dean swallowed. Yes he loved Sam and yes the kid was highly attractive but could he have sex with him? Vampires mated for life after all. But it would help tie Sam to them more firmly. Dean looked at Bobby, his decision made and Bobby's eyes widened before he nodded and stood.
"Bobby? Where are you going?" Sam demanded and Bobby sighed.

"Just into the bathroom Sam. I won't watch you two. The bathroom's safe, you have to come through here to get in there." Bobby assured him and Sam nodded. Bobby grabbed the laptop and retreated.

Sam turned to look back at Dean and Dean smiled at him, nudging at Sam so they could get up and then he led Sam to the bed Sam used. He sat down and pulled Sam back into his lap. Sam smiled and leant in to kiss him, Dean returning it with equal passion. Sam began tugging at his clothes so Dean yanked his shirt off, figuring Sam might just rip it off if he didn't. Sam yanked his own off as well and Dean raised his hands to Sam's chest, hesitantly touching the cold skin. Sam gasped and pressed closer, obviously loving the heat of Dean's own skin.

"Dean more." Sam murmured so Dean lay back, pulling Sam down with him so that Sam was laying against his chest, fighting the urge to shiver at Sam's coldness. Sam's hands roved over his chest and Dean moaned, returning the touch. This time Dean didn't stop him when Sam reached for Dean's belt and Sam smiled widely.
"Love you Dean." Sam whispered as he unzipped Dean's jeans. Dean reached up to cup Sam's face.

"I love you Sammy." Dean whispered and Sam leant in to kiss him again. Dean lifted his hips so Sam could pull his jeans and underwear down, leaving him fully naked beneath Sam who still had sweatpants on. Dean put his hands on Sam's hips and Sam lifted up off him enough for Dean to shove them down. Once he'd kicked them off he lowered himself down, letting their bodies fully touch for the first time and they both gasped at feeling a body so different in temperature to their own. Sam practically melted into the heat of Dean's body even as Dean fought not to shiver at Sam's coldness. To distract himself Dean claimed Sam's mouth in a gentle kiss, running his hands up and down Sam's back. Sam moaned and began shifting his hips against Dean, making them both moan. Dean's hands went to Sam's hips, guiding his rhythm and Sam broke the kiss to nuzzle and nip at Dean's throat with his blunt human teeth. Sam began moving down Dean's body, kissing, nipping and sucking at his skin and Dean let him, lost in the sensation of Sam's cold skin on his hot. So when a cold mouth enveloped him it was too much. Dean lay on the bed, panting, as Sam came back up to kiss him again and Dean could taste himself in Sam's mouth. The only thought that made it into his mind was that thankfully Sam's teeth hadn't dropped during that. Sam rubbed himself against Dean so Dean reached down with a hand to help him and soon Sam was slumped bonelessly over him. Dean wrapped his arms around him, hugging him and kissing the top of his head.
"Good?" He asked and smiled as Sam nodded before looking up.

"More?" Sam asked and Dean hesitated. Getting each other off was one thing but what Sam wanted?

"Sam can we wait, please?" He asked and Sam looked at him curiously so Dean put his hand against Sam's cheek and Sam rubbed his face against Dean's hand.

"Why?" Sam asked and Dean sighed.

"This is easier for you Sammy. But I'm still human and this is a big change. I need time to adjust." Dean admitted and Sam frowned.

"You don't want me?" Sam asked and Dean hugged him tighter.

"I do Sammy, always. Love you. Please. And not with Bobby just a thin door away. I want it to be…special." Dean told him and while it was true he didn't want Bobby to be able to hear them going that far he'd never been one to need sex to be special before. But with Sam? If they were going to do that then it had to be special because Dean knew Sam would not allow him to be with anyone else after.

"Okay." Sam finally said and Dean relaxed, kissing him softly.

"Thanks."

Bobby relaxed when the noises stopped. Being able to hear those two doing that was not his idea of fun but he'd do what it took to help Sam stay with them, as long as Sam didn't want to do that with him. He just hoped Dean knew what he was getting into or else things could end up going very bad.
