He stared down at Cas for several minutes, unable to figure what to do. he tried to move slowly, but the angel gripped his shirt tightly. Cas gave a small whimper each time Dean tried to pull away. when Dean finally gave up trying to escape, Cas nuzzled his head further into his chest.

dean laid there for several minutes before he eventually drifted off to sleep. when he had woken up, he noticed he had turned in his sleep. he was now face to face with a still sleeping Cas. their noses were practically touching, and he had his arm wrapped tightly around the angel. two thought flashed in Dean's head at that particular moment. one was that he was inches from the face of a male student. the second was the desire to stroke the angel's wings. since he was still half asleep his reasoning part of his brain wasn't operating properly. before he could contemplate his actions, he began softly stroking the angel's wings.

several things happened in that split second. one, a golden chain appeared around Castiel's neck. second Cas woke up in sudden realisation of what just happened. and third was Dean finding out Castiel's secret. they jumped out of the bed faster that a human could blink. cas was in tears by this point because he had finally found out that he was an omega angel.

"do you realise what you have just done," he cried as he grabbed the nearest thing to him and chucked it at dean. "there is a reason why it is forbidden to touch an angel's wings. to do so bounds you to them. what makes it worse is bounding with and omega makes the omega unable to resist the call or their alpha."

Dean stood there in shock, horror, and oddly desire. he stared at his hand, knowing that he just committed a dangerous act. he managed to dodge the thrown object, which was a very sharp pencil, and tried to apologise to Cas. he didn't mean for him to be accidentally bound to Cas. from what he knew of angel ways being bound was like a marriage sentence. one that couldn't be undone. he tried to move close to Cas, but instead, cas booked it out of their shared space.

cas ran as fast as he could. he wanted to get as far away from dean as possible. he had hoped that he could get away fast enough for the blind to be incompleted. though he knew the only way to fully complete the bounding was to mate before the omegas tattoos were completed. he glanced down at his hands and saw the tiny marking beginning to form on them. when the tattoo is done it would look like a golden roped knot with the name of their mate written in Enochian wrapped inside it. Cas was ashamed that he was an omega. he always assumed he was a beta. he knew that his brother thought he didn't know about the mating system between angel's. but he learned about it during a health course in school.

he was so caught up in his thoughts he didn't watch where he was going and bumped into someone. when he looked up to apologize, he saw that it was his brother. Gabriel was surprised to see his brother. he was even more surprised to see a gold chain around his first he thought it was just a normal chain, until he saw the look in his brothers eyes. it was the look of hurt, betrayal, anger, and confusion. then his brother spoke words he thought, no he hoped he'd never hear.

"why Gab, why didn't you tell me i was an omega?" Cas cried out.

" because little brother, i was hoping to spare you from the embarrassment. how did you find out?" Gabriel asked. but he had a feeling he already knew the answer. his little brother was mated to someone.

Cas explained to his brother what happened. how he had woken up in Dean Winchester's bed of all places. how Dean had been stroking his precious wings. then a moment later the golden chain of omegas appeared on his neck.

"oh, Cas i am so sorry. i should have told you sooner. i could have prevented this. i'm gonna kill that son of a bitch demon." Gab put his face in his hands. he felt like he betrayed his brother. his mother would be pissed if she were alive to find out he allowed Cas to be bound to a demon. he had failed in his promise to protect his brother. however there was a sliver of hope in his eyes. he knew that in order to complete the bond his brother needed to mate with dean. so he asked his brother, unable to hide the hope in his tone "did you...umm sleep with him?"

Cas looked disgustedly at his brother. he punched his brother in the chest. "what do you think you fucking dickface." he barked out, Gabriel shrugged. "of course i didn't fucking screw him. i'm not an idiot, i know that screwing him would complete the mating and the knot would be complete."

Gabriel sighed in relief. he then looked into his brother's eyes with a dead serious look. "look the next week is going to be difficult for you. you are going to become very..umm sexually attractive. you are going to emitt off a pheromone that attracts the alpha group. you are going to feel the urge to be close to Dean." Gabriel started. Castiel began to look like a deer in headlights.

"no. i can't. this can't be happening. i-i-i- no." he stuttered and tried to back away from his brother. but gabriel grabbed ahold of his shoulders tightly and continued what he was saying.

"listen Cas, i'm trying to save you from making a mistake and being bound to Dean forever. now you are going to feel drawn to Dean. but you have to try to fight it. if you don't you're going to end up sleeping with him. you have to try to stay away from Dean at all cost. the closer you are the faster the knot forms. you can sleep in my dorm for the next week. if you can manage to stay away from him for an entire week the knot will fade." Cas nodded numbly and let his brother drag him to his room.

Gabriel was rooming with a human jock boy. the human looked at Gabriel in confusion when he brought a boy into the room. then shrugged as gab said it was his brother and that he was staying with them for the next week. Cas was so stressed that he grew worn out and fell asleep as soon as his brother laid him down on the bed.
