Sam, Dean, and Gabriel sat on a bed as they watched Castiel repair the damage that had been done to the room. As the last splinter was replaced on the door, Dean stood and approached Castiel.

'Are you sure you should be doing magic-magic?' Dean asked as he came up beside Castiel and examined the door. He let out a low whistle, impressed with Castiel's work. The door looked as if nothing had happened.

'It's all right,' Castiel replied. 'Ruby knows where we are, so we aren't exactly giving away our position. She'll be busy preparing for the next time. I would say that we have at least a day to work on our own plan.'

Dean ran his hand through his hair and shifted uncomfortably. 'That's not enough time,' he muttered.

'You're doing better than I could have ever imagined,' Castiel said as he turned to face his witch. 'You have power, talent…imagination… All you need to learn is control.'

'You should probably start practicing,' Sam said. He nodded to Gabriel and stood. 'I'll see if I can't dig up any information on Ruby.'

As Sam left the room, Gabriel lingered behind. 'Uh, Cas? Do you… You wouldn't happen to know of any way to guarantee that Sam would end up in my head if he decided to dreamwalk again, would you?'

Castiel sighed and walked over to the nightstand between the two beds and picked up the notepad and pen that laid there. 'Yes, but… It will require him to use magic. Where will he get the energy?' he asked as he scribbled a symbol and a short set of words.

Gabriel shrugged and pulled a pair of C batteries from his pocket. 'I figured we could try the battery route again.'

Castiel nodded and tore of the top sheet of paper from the pad. 'Have him draw the sigil on both of your foreheads. It doesn't need to be blood. A pen will work just fine. When he manages to tap into some power, have him recite the spell then kiss your sigil,' he explained.

'Hey, lucky you,' Dean said as he passed by. 'You get a kiss outta the deal.'

Gabriel grinned stupidly as he left the room.

Castiel turned to watch Dean change clothes and quickly looked away when Dean glanced over his shoulder at him. He didn't understand the jealousy that Dean felt for Sam and Gabriel. If his witch wanted the same thing, then why didn't he do something about it? Or at least say something? With a sigh he set to work on undressing. When he pulled off his undershirt, an interested spark slammed into him through his connection with Dean.

It was the same feeling he felt before. The lust…the need… Jerkily, he began undoing his pants and licked his lips self-consciously. He let his pants pool around his legs on the floor and gave an experimental stretch, raising his arms above his head and arching his back. The feeling intensified and Castiel couldn't stop the small gasp that escaped his lips. Embarrassment seared into him, and the bathroom door slammed shut.

Castiel peeked over his shoulder, finding himself alone in the room. With a sigh, he shucked off his underwear and slipped into one of the beds. He moaned quietly as a mix of desire and annoyance drifted along the connection. He turned onto his back and closed his eyes. If he could just fall asleep, he wouldn't have to deal with the mixed emotions.

.-.-.-.-.

The moment Dean shut the door, he leaned against it and exhaled loudly. What was he supposed to do? Castiel was amazingly hot, and the way he moved… He would have thought it was on purpose, but all he could glean from his familiar was curiosity. And, at that moment, a hint of frustration.

'Fuck you,' Dean muttered under his breath as he turned on the shower. As he waited for the water temperature to adjust, he couldn't help but feel annoyed with both himself and Castiel. He sighed as stepped into the shower. He was already half-hard from watching Castiel strip and desperately wanted to jerk off. But how could he take care of himself without sending all his feelings to his familiar?

As he soaped up, he wondered if he could try creating a barrier. Something that would let Castiel know that he was still there, but wouldn't let him 'hear' what he was doing. 'Like a window,' Dean muttered to himself. Castiel would still be able to see him through their connection, but all communication would be silenced.

'You're more than welcome to try,' Castiel's voice echoed in Dean's head.

Dean stiffened, hyper aware of his surroundings.

'You were…thinking about your…window idea rather loudly,' Castiel's voice explained. 'I would encourage you to try, but… Why do you require the privacy?'

Dean ducked his head under the stream of water, closing his eyes. He tried to explain how he wanted to jerk off without a familiar in his head. He laughed at Castiel's embarrassment and stuttered apologies.

After a moment of silence, Dean stood straight and tried to imagine everything that went into creating a window. He could feel a tug at his core and a light tingling running up his spine as he thought about the wall that would surround the window. He had installed a window before, so he ran through the motions in his head. Then, he added a second pane. Just in case.

He opened his eyes and looked around. He had no idea of whether or not it had worked, so he hopped out of the shower and opened the door to the bedroom a crack. 'Hey, did it…uh…' He trailed off as he caught Castiel's wide-eyed expression and swallowed as his eyes traveled down.

The blankets were pooled around Castiel's hips, and his hands were lightly clasped on his lap. He nodded at Dean and offered a small smile. 'I can still feel you, but I can't sense what's going on,' he replied.

Dean nodded and shut the door. As he stepped back into the shower, he let himself relax with a long sigh. With Castiel's appearance still fresh in his mind, it was hard to keep his thoughts away from wondering what it would be like to hold Castiel in his arms. He already had an idea of what Castiel sounded like.

.-.-.-.-.

Castiel sighed happily when the door shut. Dean's spell might not have required much magic, but it was complicated enough to make up for it. And with their bond strengthened, Castiel could feel every little intricacy that Dean had unwittingly woven into the spell.

He eyed the door for a moment before letting himself go. If his witch was busy pleasuring himself, then he was permitted to thoroughly enjoy Dean's magic as it coursed through him.

.-.-.-.-.

Gabriel entered the room he was sharing with Sam to find his witch shirtless and rummaging through a bag. Through their bond, he could feel that Sam was searching for something. Something to help with more searching… 'Adapter,' he said when his eyes fell on the closed laptop resting on one of the beds. 'Front pocket under the candy corn.'

Sam frowned as he retrieved the power cable. 'Why…?'

Gabriel waved the paper he carried and laughed. 'Uh…well… I wanted to know if licking it would be the same as sticking a fork in a socket,' he replied.

'Are you okay?!' Sam asked as he came up to Gabriel. He cupped Gabriel's face and didn't miss it when Gabriel leaned into the touch. 'Did it hurt? Can you get hurt?'

'I'm fine. Really. I was just curious.'

'Curious about being electrocuted…' Sam dropped his hands and shook his head.

'Yeah. Fork has a lot more bite!' Gabriel's smile faded at Sam's concerned stare. 'I promise I'm okay.'

Sam reluctantly nodded and looked down at the paper that Gabriel held. 'What's that?'

'Oh! This,' Gabriel said as he held the paper out to Sam, 'will help with your wandering habit. If you dreamwalk, you'll end up in my dreams. A lot safer than ending up in some stranger's dreams. Or, God forbid, Ruby's.'

'Sure. How's it work?'

Gabriel held up an eyeliner pencil. 'Draw the symbol on our foreheads, then recite the spell. It'll last until you wipe it off,' he explained.

Sam took the pencil and looked at the neatly drawn sigil and precise script on the piece of paper. 'May as well get it out of the way,' he muttered. He took the paper and headed to the bathroom. 'At least it should be easy to draw…'

He started with a circle and worked his way from the bottom and around, pausing every now and again to remind himself to draw in reverse. When he finished, he turned to face Gabriel with an uncertain smile. 'Well?'

'Looks good. Now, me!' Gabriel closed his eyes as Sam traced the sigil onto his forehead, carefully taking his time.

'So…where am I going to get the power to do this?' Sam asked as he put the finishing touches on the sigil.

Gabriel pulled the pair of batteries from his pocket and offered them to Sam. 'Figured we try this again,' he replied. He dropped them when Sam leaned down and kissed him. 'S-Sam?' His voice wavered as he spoke.

'Or…we could try this out,' Sam said before kissing his way down to Gabriel's neck.

'Oh! Uh…are you…sure?' Gabriel asked. He bit his tongue and rolled his eyes. 'Of course you're sure… Why the sudden change in—oh! Oh, yeah… Right there… You kinda blew me off earlier.'

Sam laughed into Gabriel's neck. 'Jumping me before I get a chance to relax isn't the best way to…lure me in,' he said as he guided Gabriel to the empty bed.

The backs of Gabriel's knees hit the edge of the bed and he half-fell. He stared up Sam, his witch towering over him. He smirked and scooted back as Sam crawled onto the bed and cornered him against the headboard. He could feel excitement and a small amount of uncertainty coming from Sam. He pushed forward and caught Sam's lips with his own as he eased his shirt off.

'Probably a bad time to ask…but how does this work, exactly?' Sam asked breathlessly as Gabriel tugged on his belt.

'Just let it happen,' Gabriel replied. He nipped at Sam's neck as he managed to undo the belt buckle. 'Your body and magic will know what to do.'

'More foolproof than the—ah!—the batteries?' Sam groaned at the release of pressure as Gabriel unzipped his jeans.

Gabriel nodded and palmed Sam's erection, a thin layer of plaid fabric separating them. 'Definitely. And, it's more fun!' He gasped as Sam pushed him back down and pulled his legs up. His thighs pressed tight against Sam's hips, and he moaned loudly as Sam ground against him.

'Definitely more fun,' Sam agreed. He paused as he felt a tingling sensation settle over him.

Gabriel pulled Sam down and kissed him. 'Don't stop,' he quietly urged. 'It's normal. You're…oh…accepting the… Ah! C-charge! Keep mmm!'

Sam tugged on Gabriel's pants, and the familiar squirmed to help remove them. 'Commando, huh?' he asked with a grin. He let Gabriel sit up and pull at his own jeans, feeling his desire intensify with every second and every inch of skin that Gabriel exposed and kissed. 'I feel… Oh… I want this, but…even more than before…'

'My fault,' Gabriel sang as he fully removed Sam's jeans. 'Our connection… Both want it… Really…really want…need…'

'Don't move. I'll grab some…' He was about to pull away when he could feel the reassuring sense that everything he needed was right there. He looked down at Gabriel questioningly.

Gabriel lightly crossed his arms above his head as he lay back down. 'No need. I come pre-lubed.'

'…What?'

Gabriel sighed and hooked his legs back around Sam's hips. 'One of the perks of being a familiar,' he explained. 'I can make my own clothes…create my own furniture…lube myself…'

'That's…useful,' Sam replied. 'Weird. But useful.'

'You'll have to stretch me, though. Thought you might enjoy doing that yourself.'

'What about—'

Gabriel snapped his fingers and a condom packet dropped on his chest. 'I'm clean, but if it makes you feel better, there ya' go.'

.-.-.-.-.

Dean dried off and pulled on a pair of sweat pants. How was he going to explain what he was feeling to Castiel after he broke down the barrier? Maybe he should talk to him first. If neither could read the other's thoughts, then they would at least be on even ground. He opened the door and stepped into the bedroom. And immediately wanted to run right back into the shower and pick up where he left off.

In the center of the bed was Castiel, moaning softly and writhing. He had managed to kick the blanket down to his knees, and Dean had an eyeful of Castiel's half-erect cock.

'Er…C-Cas?'

Castiel turned onto his side and lazily looked at Dean. 'Mmm…your magic feels nice,' he said in a dreamy voice.

'Magic… Oh!' Dean closed his eyes and concentrated on throwing open his constructed window. The moment he felt the walls come down and his connection with Castiel flair up, Castiel gasped and groaned louder than before. He opened his eyes to find Castiel's back arched and his mouth open in a silent scream. He bit his lip as his breath caught at the sight.

'More!'Castiel begged. The wonderful feeling of want and need was back. All directed at him. 'Please…Dean…' He spread his legs and the feeling became stronger.

'Fuck.' Dean turned his back on Castiel and tried to calm himself. Behind him, Castiel's moans and cries for more became more and more desperate.

'Dean? Dean, please? I..I want… I need it… Please! Give me more?'

'I can't,' Dean replied shaking his head. 'I wouldn't know where to start, and I don't think… This isn't right!' He looked over his should, and a strangled noise caught at the back of his throat.

'Please?' Castiel asked sweetly as he stroked his cock, not breaking eye contact with Dean. 'I'll be good… You can do whatever you like with me.'

Dean turned and moved towards Castiel. He stopped himself and raised his hands in front of himself. 'No. No, I…I can't. I… Fuck. I want to,' he said, and Castiel's smile widened. 'Damn sure you know I want to. But I… You're not thinking straight!'

'I'm your familiar. It's what I'm for. You're supposed to take advantage of what I have to offer,' Castiel said as he sat up. He ran his hands over his chest and moaned as Dean's lust enveloped him. 'Don't you want what I have to offer?'

'Let's talk about this when you're not high on magic, okay?'

Castiel whine pathetically. 'Dean…I want!'

'Castiel, no,' Dean said sternly. He put everything he had into feeling calm and in control, hoping it would help Castiel.

Castiel pouted and let himself fall back onto the bed. He stared at the ceiling as waves of calmness washed over him. He blinked slowly and curled on his side, facing away from Dean and blushing brightly. 'I…I-I'm sorry,' he mumbled. He curled tighter when he heard Dean come closer. 'I thought I could…enjoy your magic without restraint.'

Dean laughed softly as he sat on the edge of the bed. 'Right. Me jerkin' off in the shower…you jerkin' off out here. Guess I just finished first.'

'I'm sorry,' Castiel repeated. He chewed on his lip as he stared ahead. It would seem that his witch was still unaware of just what he was begging for.

'No, it's okay,' Dean assured. 'Do uh… Do you need to…take care of yourself?'

Castiel looked over his shoulder in confusion. 'I don't understand.'

'You want some privacy, so you can get off?'

'Get off? Get off the bed? I'm embarrassed, not shy.'

Dean pinched the bridge of his nose and shut his eyes. 'Do you want to have an orgasm?' he asked in annoyance.

'Oh! N-no. I'm quite fine, thank you. I think. Um…I don't know!' Castiel said, turning his face away from Dean again as he felt his cheeks heat up.

'You've never…'

'What?! No! I mean, yes!' Castiel sat up and pulled the sheets onto his lap as he hunched over, staring helplessly at Dean. 'Yes, I've… I was quite thorough in the exploration of my vessel in the beginning,' he quietly explained. 'I know what…how… My body is quite responsive to external stimuli.'

'I bet. Anything else I should know?' Dean asked, his mind staring to drift where he didn't want it going.

Castiel stared at Dean. He caught the occasional thought. Muted feelings of the lust and need he felt before. His eyes narrowed minutely. Without giving into Dean's magic, he could control himself much better. So he could tease Dean a little. 'I am…flexible?' he offered. 'More so than the average human male.'

'Good to know,' Dean replied in a choked voice.

'I've upset you,' Castiel said, not letting his expression betray his thoughts.

Through their bond, Dean could feel nothing but honesty. And hints of mischief. He let out a short laugh and shook his head. 'No. I'm just…thrown off. You're…you're something else, Cas.'
