They fell into a routine after that. Dean usually woke up to find Sam trying to get the covers off or already latched on and sucking. Sometimes he'd beg for a lunchtime snack, and very few times did Dean refuse. At night, Sam didn't even have dinner anymore, only Dean would eat and then he'd nurse Sam before they went to bed.
Dean was taking a shower when Cas came. Stepping out of the shower, he almost slipped and fell right back in. "Dammit, Cas!"
"Hello, Dean. Where is your brother?"
"Out, gone to get beer. Why?"
"I was simply curious. Dean, I am aware of your… condition."
Dean stopped while he shifted through his drawers and heat rose to his cheeks. Did Cas know that Sam…?
"I can fix it; it must be terribly uncomfortable for you to lactate with no release. I am sorry I could not come earlier."
Dean let out a breath before his mind went into panic again. Did he want the curse gone? At first it hurt like hell, but now it wasn't so bad. And Sam loved it, how could he take that away? And how was he to tell Cas no? He would want to know why, and telling him his little brother liked to drink from him wasn't as normal as he would have liked.
"Uh Cas, I uh, really have somewhere to be. Come back later or something, we could… fix it then."
"Where do you have to go?"
The angel's eyes narrowed at him, but he nodded. "Goodbye, Dean."
There was the flutter of wings and Dean let out a breath, running his hands over his face. What was he supposed to do?
Sam came back later with lunch and they ate their sandwiches in silence, Dean musing and Sam too focused on eating. He crumpled up his wrapper and looked over at Dean, who raised an eyebrow at him.
"Please?"
Dean rolled his eyes, even though he loved it, and took off his shirt. He got off the chair and sat on the table, spreading his legs. Sam came over, pulling up the chair and leaning forward eagerly. He rubbed his nipple a bit, getting a few small drops out, before sealing his lips around it and drawing in.
His older brother groaned softly as he felt the pressure give and milk began flowing out, into Sam's hot, eager mouth. Sam gripped the back of Dean's knees and pulled him closer, wrapping his arms around his waist and pressing as close as he could, drinking hungrily. Then Dean remembered what happened earlier.
"Sammy…"
"Hmm?" Sam answered without once stopping his drinking.
"C-Cas came by, earlier. He said that… that he knows about the curse."
"What?" Dean's nipple fell from Sam's mouth and his brother looked up at him, eyes wide. "Does he know that we… that I…?"
Dean shook his head, breathing heavily from the loss of Sam's mouth. Milk dribbled from his nipple, drops running down his stomach. "He said that he could take it away. Get rid of it."
Sam licked the drops of milk that escaped, eyes still on Dean, a churning in his stomach. "What did you say?" he asked, nervously. He wouldn't ask Dean to keep the curse; it was his body after all, but his milk… Sam hungered for it, day and night.
"I told him to come by later and we'll see about it then," he answered, a hand going to the back of Sam's head.
"Huh." Sam lapped up the last drops of milk on Dean's stomach before taking the nipple back into his mouth and sucking, emptying his pecs. Sam sat back, stomach full, and remained between Dean's legs, looking at him anxiously.
"Are you gonna let him take it away?" he asked, trying not to sound like he wanted Dean to keep it and failing miserably.
"Do you want me to?"
Sam's mouth opened and shut. "Dean, I can't… I can't tell you. It's your body, you're the cursed one, I can't say," he protested, even though he knew they both knew his answer. Dean put a hand on his cheeks, rubbing his thumb on Sam's skin gently.
"Sammy, it only hurt when they were too full. You're taking care of that for me, so I don't have a problem. But it's up to you, if you don't want anymore, I'll get rid of it. Do you, Sam?"
Sam's eyes went dark with hunger. "Yes," he choked out, hoarsely. "Yes Dean, more than anything."
Dean tousled Sam's hair. "Then I'll keep it," he said, taking it shirt and putting it back on. Sam lunged forward, grabbing Dean's middle and laying his head against his chest.
"Thanks, Dean," he mumbled.
"Nothin' big," he replied, squeezing Sam's shoulder.
They checked out of the motel that afternoon and drove to the bunker, Dean making for the kitchen the second he walked in.
"What do you want, Sammy? Ribs? Steak? Burgers? Lasagna? Spaghetti? I'm sick of all this diner food, dinner is all me."
"No surprise from any other night," Sam said, grinning and licking his lips.
"Yeah well, I've got to tough it through all that fast food."
"Sure, I could hear your groans of sorrow as you put down that bacon cheeseburger last night. And we don't have any of the things you just listed, by the way."
"Then go get them, Sasquatch."
"Why can't you?" Sam asked, catching the keys Dean threw at him anyway.
His older brother narrowed his eyes at him. "Because I feed your freakishly tall ass, so you owe me."
Sam mumbled something below his breath but walked out, returning with several bags. Dean rummaged through, making a happy noise when he found Sam got all the ingredients for each dish he called out. Sam packed things away while Dean put on the grill pan and began making ribs.
Sam came up behind Dean as he mixed a barbeque sauce, wrapping his arms around his brother's waist. His hand came up on Dean's chest and he cupped one of Dean's swollen, warm pecs, rubbing his hand over it. Dean groaned softly, eyes almost fluttering shut.
"You know you're not getting any until after dinner," he said, trying to sound stern.
"Doesn't mean I can't feel them," Sam murmured back, rubbing his large hand over Dean's chest. His breath hitched as Sam gently pressed his left pec and he felt a drop of milk dribble out, staining his shirt.
"Sammy, I'll burn the ribs if you keep that up, and I'll cut out all the burnt parts and make you eat them if that happens."
Sam reluctantly released his brother and sat at the counter, waiting as Dean slathered the ribs in barbeque sauce and set them on two plates, pushing one across to Sam.
"Dean, I don't want so much," Sam protested, looking at the gigantic half Dean had given him, which was definitely bigger than what he was eating.
"You're kidding, you could finish that in no time," Dean said around a mouthful of meat, barbeque sauce on his lips.
"I could, but then I can't save room for what I really want," Sam stated, grinning wolfishly at Dean.
He shook his head at him. "You and that damn milk, startin' to wonder how you survived without it." He reached over and slammed a knife between Sam's rack of ribs, stabbing one piece into his own plate. Dean and Sam ate in comfortable silence, Dean clearing his plate in the same amount of time as Sam.
"I'll take them," Sam offered, reaching over and collecting Dean's empty plate, going towards the kitchen. Dean grunted, standing up. "My room when you're done."
Dean went into his bedroom, laying down on the bed. Sam came in a moment after, and Dean was pretty sure the plates were still in the sink. Nevertheless, he opened his arms to Sammy. "Come over here."
Sam walked over to him and Dean pulled him down across his lap, the bed big enough that Sam could lie on it horizontally without any part of him hanging off (a miracle, if you asked Dean).
His little brother licked his lips unconsciously and Dean reached over to unbutton his shirt. "Can I do it?" Sam asked, eyes flickering up at Dean's face. He raised an eyebrow, but let his hand fall.
Sam rubbed one hand over Dean's pec, pressing gently where his nipple was. Dean's head lolled back, landing against the headboard. Sam inched up and mouthed Dean's nipple through the fabric, soaking it in saliva. Dean felt himself begin to give and milk eased out, a wet patch appearing on his shirt.
His baby brother leaned forward and licked the patch, tasting the milk, before unbuttoning Dean's shirt and rubbing his hand over the lactating nipple, rubbing the milk into his skin. Dean closed his eyes, sighing. "Sammy…"
Then Sam latched on, gently tugging the nipple between his teeth and flicking his tongue over the end. Milk oozed through slowly before Sam started to suck harder, drawing the milk out. A steady stream flowed out and Sam lapped it up hungrily, moaning around his brother's nipple.
Dean cradled Sam's head, supporting him so his neck wouldn't begin to hurt. Sam relaxed, completely at ease now, and sucked as though he had all the time in the world, savouring every mouthful of the sweet, warm liquid.
His older brother brushed hair away from his face, watching as Sam suckled. His eyes were closed and his throat pulsed as he sucked, he was completely relaxed.
"So pretty like this, Sammy," Dean murmured, watching his little brother.
Sam hummed, a small smile tugging at his lips.
Dean cradled Sam tightly, watching as he nursed from him. A sucking sound filled the room, constant and sure. Suddenly, there was a flutter of wings and Dean looked up to see Castiel standing there, face neutral, as usual, but slightly confused when he saw Sam and Dean. Dean tensed, forgetting about telling Cas to come back later.
Sam, feeling his brother change, pulled away and turned his head to see Castiel, watching them. He jumped and began to pull away, mouth already beginning to stammer excuses, but Dean held him in place. He looked at Dean in confusion and slight panic.
Dean turned his eyes away from the angel, placing a hand on the side of Sam's head and speaking to him. "Don't you worry, alright Sammy? You just keep drinking, you didn't have much for dinner. Go on, I'll take care of this. Just ignore it."
Sam bit his lip, uncertain, but Dean's hand went to the back of his head, pulling him back to his chest ever so gently and Sam wrapped his lips around Dean's nipple, sucking slowly and unsure, but as the milk covered his tongue again, he forget everything but Dean and the milk and began to drink hungrily.
Dean looked up at Cas, swallowing hard. "I uh… I don't want you to remove the curse," he said, probably a bit unnecessarily.
"Dean, this is not natural," Castiel said, his eyes glued to where Sam was.
"I know that Cas, but he… he needs it, alright? He's taking care of me and I'm taking care of him. So just… leave it?"
"I could get rid of the curse Dean, and this is unnatural. Sam is grown, and men are not meant to breastfeed," Castiel said, his face unchanging.
Dean opened his mouth to reply, but at that point Sam whimpered and he looked down. Sam was pawing at the other half of his shirt, trying to get to the other nipple. Only then did Dean realize his pec was empty and he hurriedly pushed off the rest of his shirt.
"Easy, Sammy," he soothed, shifting Sam across so he could reach. Sam began sucking and his whimpers stopped as he concentrated on the task at hand.
"Cas… look, I'm fine, alright? I'm fine with the curse. Don't take it away, I'm good," Dean said firmly, holding Sam tightly as he fed.
Castiel blinked but his shoulders dropped by a fraction and Dean knew Cas wouldn't push. The angel walked over to the side of the bed, watching as Sam suckled, oblivious to anything else.
"The milk will do him well," he said finally. "It will make him even stronger. But you must make sure he doesn't try to substitute all his meals with it, he needs proper food."
"Yeah, I know Cas, don't worry," Dean said, a little miffed by the thought Castiel thought him so stupid. Sam groaned softly and they both turned back to him, even though he paid them no mind, intent on Dean's milk.
It was then Dean felt a blush red a beetroot rising up his neck when it hit him that Castiel was watching him nurse his baby brother. Sam didn't care, as long as he got his mouthful of milk he was dead to the world, but Dean looked back at Cas awkwardly.
"Am I making you uncomfortable?"
Dean's blush deepened more. "Yeah Cas, you are."
"I will leave you two then. Goodbye, Dean," Castiel said. He touched Sam on the head since he knew the younger Winchester wouldn't hear a single word spoken to him at that moment and flew away.
A relieved breath whooshed out of Dean and he sighed, turning his full attention back to Sam, who continued pulling on Dean's nipple. His older brother combed back his hair and leaned back, closing his eyes and letting himself enjoy the feel of Sam suckling on his nipple.
Soon the last drops were milked out and Sam released him, laying in Dean's arms and licking his lips. Dean smiled down at his brother. "Had a good dinner?"
He nodded happily. "What'd Cas say?"
"Said we seemed okay, so he'd leave it," Dean answered. Sam's eyes lit up and beamed at Dean.
"Really?"
"Really. Now get some sleep," Dean said, not moving his arms from Sam. His little brother snuggled into his chest and shut his eyes, letting himself fall asleep to the beating of Dean's heart.
