Imagine: You are Sam and Dean's little sister and are dating Castiel. One day, Dean notices a hickey on your neck. 

SLIGHT SMUT WARNING

The first day you ever met Castiel was an unforgettable one. Your big brother Dean had just been resurrected from Hell from some unknown force, and he was on a mission to find out what that force was. He had found a summoning spell, and asked you and Bobby to help, so naturally, you did. 

The moment Castiel appeared, you fell for him. His powerfulness, his adorableness, his deep voice. You were completely captivated by everything about him. Of course, he didn't exactly feel the same way about you at first. 

But, you couldn't blame, he didn't even understand human emotions. He knew that he a special connection to you, he just believed that it was because you were siblings with Dean Winchester. In the years that followed, Dean and Castiel's friendship was rocky, but it wasn't Castiel's fault, it was Heaven. And finally, Castiel had had enough, and he rebelled. 

Castiel thought he was rebelling for the greater good, but in the end, he knew he was rebelling for you. It took him another couple of years, and a few more unfortunate mishaps for him to completely realize his feelings for you. And after, about another year to make a move.But, you didn't care, because when he made that move, it was completely worth the wait.

You had been in your room looking for a case on your computer when you heard a flutter of wings. Cas was standing there, holding a bouquet of roses, a box of chocolates, and every other cliche movie item. You stood up and walked over to him. "What is this, Cas?" you asked with a smile. 

"I don't know, exactly. This is what the internet told me to get to impress a girl," he replied. You let out a small laugh and asked, "And what girl would you be trying to impress?" "Isn't it obvious?...you," he responded, tilting his head to the side in the cute way he does. 

When you heard his words, your mouth dropped open a little. The answer was obvious, since there were no other girls there, but you never expected him to say the words you had been longing to hear for years.

"Me?" you asked, making sure you hadn't heard him wrong. He nodded his head a little sheepishly as he tried to hand you the stuff. A large grin spread across your face as you took the items from him and stared at him in amazement. Your stare made him blush a little and he looked down nervously. 

"Do you like it?" he asked. You nodded your head as you set the stuff down and walked closer to him. You could tell he was nervous, having no experience with anything like this. You didn't want to rush the angel into anything so you placed a sweet kiss on his cheek and told him, "I love it, Castiel."

Hearing you say his name made shivers run down his spine, and he grin in a shy and adorable way. The rest of the night was spent watching the cliche romance movies, at the request of Cas, so he knew how to treat you.

It had been a couple of months since that day, and you and Cas had gone pretty slow, because you didn't want to scare him away. Lately, he has gained a lot more confidence, however, and he has been trying a lot more things. 

You were in the living room of the Bunker, early in the morning, watching TV before your brothers woke up and took over it, when Castiel appeared. "Hey,"  you said, automatically smiling when you saw him. He smiled back, and sat down next to you as he replied, "Hello." "What's up?" you asked him. He took your hand and told you, "Come here, I want to try something."

He then stood up from the couch, pulling you up with him, and you curiously followed him. He led you to your room, and once both of you were inside the room, he shut the door. You raised an eyebrow at him, questioning what he was doing, but he didn't respond in words. Instead, he pulled you into a passionate kiss. 

You kissed back immediately, and he pulled you closer as you ran your fingers through his hair. When you both pulled away, he looked at you with so much love and lust, that you got butterflies in your stomach. You knew that Cas wasn't ready to go all of the way, but the look he gave you meant he was ready to go farther than he ever has before. He pulled you into another kiss, turning so that your back was facing the wall, before pushing you up against it.

He broke slightly from the kiss, biting your lip, before connecting your lips again. He ran his hands down your leg, and gave them a slight tap, telling you to jump. You got the message, and you jumped up, wrapping your legs around his waist. His hands grabbed your ass as he pushed you even further into the wall with his body. 

His lips then travelled down your jawline and down to your neck, and then down to your collar bone. This is where he sucked and nibbled, something you didn't even know he knew how to do. You moaned as he left his marks all over your neck. 

When he was done he connected his lips to yours and was going to continue when there was a knock on your door. "Hey, rise and shine, sleeping beauty," you heard Dean say through the door.

You quickly unwrapped your legs from Castiel and stood up straight, fixing your hair. You hadn't exactly told either of your brothers about your relationship with Cas. You see, they would totally freak out and be there overprotective selves, which you loved and hated them for. 

"No, just give me a second," you replied, as slight panic set in. "Okay, listen, Sam made us breakfast so just meet us down there when you're ready," he responded. "Okay," you told him. You heard his footsteps depart, and you looked back into your loving boyfriend's eyes. 

"I should go, before he comes back up," you said, sad that yours and Cas' moment got interrupted. Cas gave you a small smile and replied, "We'll continue this later then." You smiled and Cas pulled you into another kiss. "I love you, Y/N," he told you. "I love you too, Castiel," you replied. He smirked at you, before disappearing and you quickly fixed your appearance in the mirror, covering up the bruises that were already starting to form with your hair. 

You walked down the stairs and found your brothers sitting in the dining room, eating their breakfasts, and at the seat right next to Dean, there was a plate. You thanked Sam before sitting down and beginning to eat breakfast. 

You and your brothers had an interesting conversation about which monsters are hardest to kill, a typical topic for you and them to talk about -- monsters. During the conversation some of your hair had moved from the place you had perfectly set it in to hide your neck. Dean had only caught a glance, but that was enough for him.

"What's on your neck?" Dean asked in a serious tone, stopping yours and Sam's laughing right away. Your eyes widened as you quickly moved your hair into the place you had had it before. "Y/N, what's on your neck?" Dean repeated. 

You let out a sigh as you looked at your brothers. Dean was giving you a death glare, while Sam was staring intently while he took a drink of his water. "A hickey," you muttered, knowing you couldn't lie to them. Sam nearly spit out his water as those words left your mouth. "A hickey?! How the hell did you get a hickey?!" Dean asked. 

You didn't know if Cas was ready to tell them yet, so you replied, "A bar hook up." "We haven't been to any bars recently," Sam responded, now paying full attention. You shot him a glare before saying, "Fine, from my boyfriend." 

"Boyfriend??" Dean asked, looking between you and Sam in disbelief. "Who's your boyfriend?" Sam questioned. "Cas," you muttered, taking a drink of your water at the same time so they couldn't exactly hear you. 

"Who?" Sam asked. You cleared your throat, and placed your water down. "My boyfriend is Castiel," you stated clearly. Shock washed over both of their faces as Dean said, "Oh, hell no." He then stood up, looked towards the ceiling and yelled, "Castiel, get your feathery ass down here." 

Within moments, Cas had arrived. "Hello, Dean, Sam...Y/N," he said, giving you a small smile. "Oh no, don't you 'hello' us," Dean replied, walking towards him. "What's going on?" he asked, looking towards you. 

"He found out about us?" you told him. "He found out about us?!" Cas asked, looking terrified as he began backing away from Dean. "Damn straight I found out about the two of you. Here's a hint, next time you want to have a secret relationship with my sister, don't leave marks all over her neck. I can't believe this! My best friend and my sister!" Dean yelled at Cas who was continuing to back away. 

You looked over at Sam who was just watching the scene go down in amusement, and it couldn't help but make you chuckle a little bit. You stood up and walked over to Dean. "Dean, I'm sorry we didn't tell you, but before you make any decisions about our relationship, you should know that I am in love with him. There is no other man, or angel, who has made me happier," you told him.

"And I am completely in love with your sister, at least as far as I understand love to be, and it is true, she makes me very happy," Castiel told Dean. Dean looked between the two of you before stating, "Fine, but I don't want to see you too making out everywhere, and Baby is definitely off limits for that kind of stuff with you two."

Dean then walked off and Sam followed him, giving you guys some privacy. "Well, that went well," Cas said, walking closer to you. "Yeah, but at least we don't have to sneak around anymore," you told him. He smiled and pulled you into a kiss. 

"Ah, what did I just say?!" you heard Dean say as he suddenly entered the room. You and Cas broke apart, and he walked away again, muttering under his breath. You laughed at your older brother, before interlacing your fingers with Cas' and leading him to your room. 

"Come on, let's go finish what we started," you told him, making Cas smile as you opened the door to your room, and let him in, before shutting it again. It didn't open again for the rest of the night.
