Title: You Can Do That

Pairing: Dean/Castiel

Rating: T (Maybe K+?)

Prompt: HS!AU Dean coming out for the first time while his boyfriend over for dinner

Notes: Unbeta'd. This is actually kind of based off my own coming out so I hope you enjoy!

"I can't do this," Dean said for the umpteenth time. Castiel sighed from where he was sitting at Dean's desk, trying in vain to finish his lab report for chemistry.

"So don't," Cas shrugged, wiping a hand down his face. He saved the document before closing his laptop. "If you don't want to come out, don't. I just suggest it because one of these days Sam or your parents are going to walk in on us having sex and out you that way, so," Castiel turned to face Dean, who was laying out on his bed, staring at the ceiling, "Might as well come out on your own terms."

Dean blew out a breath, sitting up. He leaned forward, pressing the palms of his hands in his eyes. "I don't – " He sighed, looking for the right words. "I want to, Cas, I really do, I mean I would love nothing more than able to hold your hand in front of them, to kiss you whenever I want but what if…" Dean trailed off, looking at Castiel with a lost expression.

"What if they reject you." Castiel finished, matching Dean's expression with his own understanding look.

Dean nodded, burying his head in his hands again. Castiel gave him a sad smile, getting up to sit beside Dean. The mattress dipped under Castiel's weight, and Dean looked up at him.

"Don't look so down," Castiel said, bumping shoulders with Dean. "My offer still stands, you know," Castiel finished, referring to his offer of having Dean stay with him if his parents ever kick him out.

"Yeah, like Michael will go for that," Dean scoffed, smile beginning to form on his lips. "He's already threatened to kill me for corrupting his baby brother's virtue."

Castiel out right laughed at that, body quaking. "Wait until we tell him that it was me who introduced all the kinks and who seduced you," Cas gasped out between laughs. Dean finally broke at that, leaning heavily against his boyfriend as he laughed.

"Kids! Dinner!" Mary called from downstairs. Dean stopped laughing, sighing again.

"Well, now or never, right?" Dean asked, tucking his face in Castiel's neck.

"Right," Cas answered, stroking a hand down his side.

"A kiss for luck?" Dean muttered against him.

Castiel nodded, cupping Dean's face before kissing him softly. He pulled back after a second, smiling, "Let's go get 'em."

"So, how's the folks?" Mary asked in Castiel's direction, taking a sip from her wine glass.

"They're good. Lucifer is being rebellious as always – got a new piercing. Michael had a field day with that one. Oh and Gabriel got a new job at some bakery in the city. I told him if he doesn't diet that job will have him turned into the size of a giant whale within a week," Castiel said with a laugh, blue eyes lighting up.

Dean smiled at him, falling into the familiarity of family dinners with his boyfriend. It always made his heart clench almost painfully in his chest from affection when he saw how easily Castiel fit into his life. Somehow – over the course of the ten years they'd known each other – he had carved himself a little niche in Dean's heart and life; it had gotten to the point where Dean didn't even feel whole without Castiel around and that scared him. But he's a Winchester – putting emotional freak outs on hold is his specialty.

"So, Sam, how is that lovely Jess we've been hearing all about?" Mary asked teasingly, taking a bite of pot roast.

Sam flushed scarlet, looking down at his plate. "She's good. She asked if I wanted to come over next week to study for out biology test."

"That's my boy," John called from the end of the table. Sam flushed again, scrapping up another bite.

Dean glanced over at Castiel, catching his eyes. Cas gave him a small nod, grasping his thigh under the table in support. Dean blew out a breath and then cleared his throat.

All eyes were on him and he felt his mouth go dry. He looked over at Castiel, Cas giving a tiny smile and another squeeze. "I, uh, have something to say."

His mom gave him a smile, gesturing with her had for him to go on. Dean took a deep breath, "I'm gay."

"God damn it!" John cursed from the end of the table. His mother fist pumped in the air, the other hand held out, palm up, towards his dad.

"You owe me fifty bucks!" She said gleefully.

Dean and Castiel blinked at each other in surprise. "Wait," Castiel said slowly, apparently piecing it together faster than Dean, "You betted on your child's sexuality?"

"Not exactly," John grumbled, fishing out his wallet from his back pocket.

"We betted on when he would come out," Mary said, smiling at both of them. "I said in high school probably a little after he got together with you," Mary pointed at Castiel. "But your father said not until collage."

"So wait," Dean called, "How do you know I'm dating Cas?"

Sam snorted from where he was seated next to Dean. "It's freaking obvious dude, and that was before we found the four empty bottles of lube after the weekend we left you guys alone."

Dean's mouth snapped shut from where he was about to protest, flushing along with Castiel.

"Sam!" Mary chastised, a fifty dollar bill fisted in her hand. Sam held up his hands in a peace making gesture, moving back to his food.

"So you guys knew." Dean summarized, lacing his fingers with Castiel's under the table.

"Pretty much," John said, having the presence of mind to at least look a little sheepish.

"Oh," Dean said, and Castiel could see the glint in Dean's eyes. "So I can do this now."

He grasped Castiel's neck, bringing Cas' face towards his and their lips met. Castiel threw his hands around Dean's neck, Dean's other hand fisting in Cas' hair. Castiel traced Dean's bottom lip, Dean's lips parting instantly, tongues dancing around in each other's mouth.

Someone cleared their throat after a few minutes, and they finally broke apart smiling at each other. Dan nipped Castiel's bottom lip one more time before facing his family.

"Yeah, you can do that," Mary said, smiling at the couple.
