-MWM-
Gabriel sighed as he stepped out of the shower, having calmed down somewhat. He knew that he needed to have a serious talk with Castiel, and he'd put it off long enough. Too long, actually, given Castiel's attempt this morning. He quickly dried off, then realised that he'd stormed in here without actually grabbing any clothes.
Not looking forwards to being naked around his brother, even for a few minutes, he wrapped his towel firmly around his waist and stuck his head out of the door. There was no sign of Cas in his bedroom, so he quickly slipped out and started to get dressed. He couldn't hear movement in the rest of the apartment, and suddenly Gabriel started to worry. Looking at Castiel's track record of the last two years, he obviously didn't do well when things went wrong.
Pulling the nearest shirt over his head, Gabriel hurried out to the living room, only to find that all of Cas' stuff was gone.
"Shit!" He swore, kicking the couch. This wasn't meant to happen! He never meant to push Cas this far away. He had to find him.
Gabriel sat down and thought for a minute. Cas didn't know anyone in Los Angeles… or did he? He seemed to be getting pretty friendly with that chick at the party last night. Gabriel had seen them dancing together several times, if dancing was the right word for it. More like sex while clothed.
Having his first clue, Gabriel quickly pulled on his shoes, grabbed his keys and headed for Kali's. She might be a handsy bitch, but Kali was also fiercely protective of those she considered hers, and she'd never quite gotten over Gabriel.
Once there, he described the girl Cas had been with the previous night. Kali looked confused for a moment, then murderous.
"Katie! I'll kill her myself, I told her not to come here anymore."
"What do you mean?" Gabriel asked, a sinking feeling in his stomach.
"She's a pusher," Kali informed him, already flicking through her phone for Katie's number. "Goes around to parties, gives away samples of drugs, then sends people on to one of her dealers."
"Shit!" Gabriel swore again. "He's not even been clean a month! I thought he'd be okay here."
"I told her she's not welcome at my parties," Kali fumed. "I fucking told her to stay away!"
It took a few minutes, and several creative threats from Kali, mostly involving fire and certain body parts, before Katie told her where she'd sent Cas. Kali relayed the information to Gabriel, then continued to tear into her former friend. Gabriel didn't stick around to listen, instead heading out of the door. This was all his fault, he should have been keeping a closer watch on his little brother… he should have known not to trust anyone else with his safety or wellbeing.
He got to the park and didn't immediately see anything. There was a large clump of bushes near the back, though, which meant there was a fairly secluded area which would be perfect for a little inconspicuous dealing. Gabriel approached it, and arrived just in time to see a man with his cock down Castiel's throat.
Gabriel froze, unable to believe what he was seeing. Cas was apparently enjoying himself as the stranger thrust down his throat a few times, before coming in his mouth. Gabriel couldn't move as he watched Cas clean the man up and tuck him away, all the while being patted like a well-behaved dog. His stomach clenched - then he saw the man place something smaller in Cas' mouth, and heard the comment.
"Damn that was good, kid. You certainly deserved this. When you need another hit, come find me."
"You bastard!" Gabriel shouted and launched himself at the man. There was a brief scuffle, before the stranger managed to get away and took off at a run. Gabriel wanted to chase after him and beat him to a pulp, but Castiel was lying curled up on the ground, smiling as he ran his fingers through the dirt. He had the sudden urge to stick a finger in Cas' mouth and make him vomit up the drug, but given he'd just been deep-throating some random drug dealer, Gabriel didn't think a finger would really bother him.
He crouched down and gently tugged at Castiel until they were both standing again. Cas didn't offer any resistance, in fact he seemed happy to go along with it. When they were standing properly, Gabriel suddenly found that Castiel was clinging to him, nuzzling into his neck before attempting to kiss him.
"Cas, no, stop it. You've just had a stranger come in your mouth, I'm not kissing you." Gabriel managed to push him down, heart breaking a little as Cas didn't seem to register what was being said. "C'mon, let's get you home."
He kept a hold on Cas as they walked, having to take most of the younger boy's weight. Cas was laughing at something then, stumbling over his own feet, and Gabriel again had to stop Cas from kissing him. He wasn't sure what it was that Cas had taken, but whatever it was seemed to have taken away all his inhibitions at once.
It was slow going, getting him back home, especially when Cas wanted to get on his hands and knees in the middle of the road. Gabriel ended up practically dragging him the last block, and heaved a sigh of relief when they were inside the apartment building. Then he noticed that Cas was getting distressed, whimpering and shaking his head. His pupils were blown wide, and Gabriel wasn't sure if he was even seeing anything. So he did the only thing he could think of, and wrapped Castiel in his arms, holding him tight when they finally got into the elevator.
"Shhh, Cas, it's okay," he started whispering into Castiel's ear. "I'm here, everything's gonna be fine. I'll take care of you, like I always do. I'm not leaving you, not now and not ever. You don't need drugs to stop being lonely, I'll always be here. I promise."
He kept up the litany of soothing nonsense as they rode up to the correct floor, then managed to get Cas into the apartment. Castiel had closed his eyes by then, and Gabriel faced a constant struggle to keep him from falling over anything. He dumped Cas' bag near the couch without actually letting go of Castiel, then pulled him into the bathroom, all the while rubbing Castiel's back as gently as possible.
Gabriel quickly squirted some toothpaste onto a toothbrush and stood behind him to help clean Cas' mouth. He finally accepted how things were going to end up - he'd do whatever it took to stop Cas from doing this to himself again, even if it meant bedding his little brother - but refused to taste someone else in Cas. His heart dropped a little as Cas obviously started sucking on the toothbrush, clearly thinking it was something else. Then it seemed to click that he wasn't sucking someone's cock, and he started to fight against Gabriel.
"Hey, it's okay, it's just a toothbrush," Gabriel whispered. "It's okay, you know this, you know what's happening, some part of you does I know it." He wrapped his free arm around Castiel's torso to hold him still as he finished brushing Cas' teeth for him. Finally deeming the task finished, Gabriel pushed Cas forwards gently. He seemed to get the message and spat out the toothpaste from his mouth. Gabriel decided to try some more and fills his hand with water, tilting Cas back as he poured it in his mouth. Unfortunately Castiel didn't seem to recognise the action and started to choke. Gabriel quickly tilted him forwards again, and Cas spat everything out. Gabriel felt guilt wash over him as he saw that Cas was crying and shaking, obviously scared.
Gabriel turned his brother around and held him close. Castiel tried to burrow into him, getting as close as physically possible, sobbing in earnest now. Gabriel was starting to get scared, realising that he might have made things worse. He just didn't know what to do to make things better. He decided to go with something Cas had obviously wanted for a while, and pressed a gentle kiss to his mouth.
Castiel kissed back quickly, apparently recognising this. Gabriel couldn't stop the groan of arousal from escaping - now that he was actively participating, he could admit that Cas was good at this. He could feel himself start to get hard, holding a warm body close and being kissed so well. He shifted, trying to will himself down, only to find that Cas was already stiff and apparently willing something different.
He pulled back a bit, biting his own lip as Castiel whimpered at the loss. Gabriel quickly moved back again, wrapping an arm around him and pulling Cas towards the bedroom. Castiel whimpered again and shook his head, but Gabriel figured it would be best to sleep off the effects of the drug.
"Come on, I've got you," he started whispering again. "We're going to have a nice nap, curled up together. You want that, don't you? Want to just stay safe and quiet with me for a while." Once in the bedroom, he pushed Cas down gently to sit on the edge of the bed and started to undress him, still talking as it seemed to be doing the job of soothing the drug-addled teen. "Getting your shoes off now. Socks too - do you even own a matching pair?"
After that, Cas seemed to get the idea and tried to help, though his hands were struggling with the idea of coordination, and the fact that his eyes were still closed. Gabriel eventually managed to undress them both. Something was giving him the feeling that skin on skin would be a comfort to Castiel, so he went along with it. He pushed Cas down again, moving him so the they were lying curled up together, and pulled the blankets over them.
Castiel made a noise then, seemed to be trying to speak, but he couldn't form the words. It obviously distressed him even more, so Gabriel leaned in and kissed him again. It seemed to help, as did the hand he kept stroking up and down Castiel's back. He noticed that Cas was trying to rut against him, and stilled his hips forcefully. He pulled back and tried to talk to him again.
"Cas, listen, we'll talk about doing that when you're mind's clear again, but I can't… I can't do this with you like this. Just wait until you wake up, I promise we'll talk then. It's going to be okay. I'm gonna take care of you."
He kept up the stream of words, sometimes speaking absolute nonsense, until Castiel finally stilled and fell into a deep sleep.
-MWM-
Cas groaned as he woke, burrowing closer to the warm body next to him. He remembered taking his favourite pill, and then there had been shouting, and now he was naked in bed with someone. Someone definitely male, given the erection nestled between Cas' legs. He sleepily began moving his hips, running a hand down his partner's back towards his ass, before a voice stopped him.
"Cas, we really need to talk about this."
His eyes flew open as he recognised Gabriel's voice. He still didn't remember anything of what had happened whilst drugged out, but given that this time Gabriel wasn't shoving him away, he let himself feel hopeful. The erection he could still feel was also rather promising.
"Talk about what?" Cas finally remembered how to work his mouth.
"This," Gabriel repeated, grabbing Castiel's hand from where it was resting on his ass. "You going out and screwing people for drugs."
"Why would you care?" Cas glared, rapidly switching to the offensive. "Not like I'm getting anything from you."
"Cas…"
"No, Gabriel, listen to me," Castiel spoke over his brother. "Do you even know what at addict is? Cutting me off from everything and sticking me in a room by myself all day with nothing to occupy my mind isn't going to stop my cravings. It just makes it worse."
"I get it," Gabriel sighed, but Castiel shook his head.
"No, I don't think you do. It's not just drugs that I'm addicted to. It's also alcohol, and sex. And you just cut me off from everything, without thinking how it was going to affect me, and I can't deal with it! I know I'm screwed up, but this is the only way I know how to get by."
Gabriel surprised him then by reaching out and pulling him closer, so that Castiel's head was against Gabriel's chest. They stayed like that, Gabriel rubbing his brothers back for several minutes.
"We obviously need new house rules," Gabriel whispered into Cas' hair. "So. You can have alcohol here or at parties we go to, but I'll be monitoring how much you have. Have too much and I'll cut you off completely. Okay?"
Cas considered it, then nodded.
"I guess that's fair."
"Good. As for the drugs… I don't like them. Cas, you've spent most of today completely out of it, and I was terrified. You had no idea what was going on around you, you didn't know who I was but you tried to have sex with me anyway. I never want to see you like that again." He took a deep breath, continuing to hold Castiel close. "If I sleep with you willingly, will you promise not to take any more?"
"What?" Cas whispered, raising his head to look Gabriel in the eyes. Gabriel nodded, looking pained.
"Your choice. I'll give in, accept you in my bed whenever you want. But you so much as taste any illegal substance and I'll never touch you again. Is that clear?"
Castiel blinked, tilting his head to one side. He wanted Gabriel, yes, but… he could still feel the craving for all the pills and powders he'd sampled over the past year. Could he stick with it, if he gave up drugs for Gabriel?
"Will you…" Cas stopped, closing his eyes as he tried to put his thoughts in order. "I'll need help. I… I still want them. I don't know how to function without getting stoned every day…"
"I'll help," Gabriel nodded. "We'll find you a class or a job, something to keep you occupied. I promise, if you're going to try to stay clean, I won't abandon you."
Castiel nodded then, and lowered his head to properly kiss Gabriel. They kept it slow but deep for a while, before Castiel pulled back again.
"You mean it?" He whispered. "Do you really want this? You kept pushing me away, I don't want to do this if you don't really want me."
Gabriel grabbed Castiel's hand and moved it down to his groin, where his erection hadn't faded.
"Cas, you've been cropping up in my fantasies for a few years now. I just… I refused to have you in my bed if you weren't in your right mind."
"Okay then," Castiel smirked, and dove at Gabriel. He finally had permission to touch, and wasn't going to pass up the opportunity.
"Woah," Gabriel was surprised to find himself suddenly on his back, Castiel licking and biting at his throat. "Easy there, I'm not gonna disappear!"
"You might," Castiel whispered, barely loud enough to hear, and it made Gabriel's heart clench. His little brother really did have issues…
Cas continued his exploration, throwing the covers away and finally looking his fill. He was kneeling with Gabriel's legs between his, and noticed that Gabriel's cock was bigger than his own. He was looking forwards to finally having it inside him. First, though, a taste.
Gabriel let out a long, low groan as Castiel started trailing kisses down his chest. He'd always had a sensitive torso, and couldn't help the noises that Cas was drawing out of him. Not that he really wanted to stop them - if it helped to reassure Cas that he wanted this, that he wanted Cas, then he'd scream his lungs out.
Eventually Castiel move down and started lapping at his cock, holding the base and treating it like an ice cream cone. Gabriel had to close his eyes at that, knowing that he couldn't last long. He determinedly didn't think about how many people Cas had sucked off to get this good. Although one image did flash into his mind - it was what had first made him aware of his brother in a sexual sense.
It had been way back when Castiel was fifteen. Dean had been at their house, and Gabriel had gone to find them both to ease his boredom, when he'd heard a groan from Castiel's room.
Thinking that something was wrong, he'd peeked in through the barely-open door, and had nearly had a heart attack. Castiel had been on his knees in front of Dean, obviously sucking him. Dean had clearly enjoyed it, from the way his head was thrown back and eyes screwed shut. The youngest boy had eventually looked down, even as Cas was staring up cheekily.
"Shit Cas, haven't you ever heard of a gag reflex?"
Cas had hummed in response, and Dean had come, biting down on his lip to try and stay quiet.
The image of Cas on his knees had stayed with him for years, and Gabriel finally knew what it felt to have Castiel's mouth - and now throat, he'd managed to swallow the whole thing down - around his aching cock. He could feel Castiel rubbing himself against his leg, desperately trying to find friction for himself.
"Casssss…" Gabriel hissed, hips jerking up. Cas just blinked up at him, then started to move his head, swallowing and humming at intervals to bring him ever closer. It didn't take long, before Gabriel felt himself rapidly approaching his climax.
"Cas, I'm nearly there, I…"
Cas merely moved back down and swallowed one last time, drawing Gabriel over the edge. As he shouted Cas' name and arched his back, Gabriel felt Cas stiffen as well, swallowing on reflex as he came against Gabriel's leg.
Castiel collapsed in a boneless heap on top of Gabriel, ignoring the fact that he still had a cock in his mouth. In the end, Gabriel had to grab him by the arms and drag him up, arranging them curled up together again. If this was what it was going to be like keeping Cas off of drugs, Gabriel wasn't sure he was going to survive it.
