Reid looked up from his tablet and rubbed his eyes. He looked at his watch and was surprised to see that it was almost eight in the evening. He had become completely engrossed in the essay he was reading. He looked around and didn't see anyone else in the bullpen. Most of the lights were off, only those in the corridors and a dim light in his boss's office were left. He wasn't surprised, he surely was finishing some report.

He collected his things and got ready to leave. He had to hurry if he wanted to get on the last train and he still had to stop by the supermarket to buy some dinner. Before leaving, he glanced toward Hotch's office. He should go and tell him to go home already, he would have time tomorrow to continue with what he was doing. He put his backpack on his desk and went upstairs. Just before knocking on the door, he heard something like a growl. Had he fallen asleep and was snoring? He didn't want to bother him either. He knew how much Hotch needed to sleep with all the stress he was enduring. He glanced through the cracks in the blind, but what he saw blew his mind.

Hotch was sitting on the couch, his legs spread apart, his head slightly tilted back. He could only see the side of his face, with his eyes closed, frowning and breathing heavily, and he could also see how he was masturbating. The big shaft was emerging from his pants, and he rubbed it at a slow, steady pace with his right hand.

He couldn't believe what he was seeing, couldn't believe his boss was masturbating in the office. He could understand that it would be difficult to do it at home, but why did he even need to do it? There was a beautiful woman waiting for him at home. He knew that many Alphas couldn't be entirely satisfied with a beta partner, but masturbating wouldn't be a solution either.

His strong hand moved so slowly over the thick, hard dick. It seemed like a mortifying rhythm, he was doing it on purpose. Spencer felt his ass tingle. He should go, but he couldn't look away. It was so big, with swollen veins and the tip dripping, all dark and throbbing. It looked like that of a beast. If something like that pierced him, it would tear his insides apart, but surely he could never feel so full. He reached for his crotch and absently rubbed his erection through the fabric.

Hotch brought his free hand to his pants and began to massage his balls. His breathing grew husky, letting out a low, almost animal growl. The base of his cock began to swell. Spencer gulped. A few drops of slick stained his underwear. His legs shook, and he fell to his knees. He closed his eyes and pressed the bulge in his pants. The scent of the aroused Alpha was so intense that it covered every other smell in the bullpen. He felt like he was being enveloped by it. With Hotch's last guttural growl as he came, he too came into his pants unable to contain a soft moan.

He sat panting, his forehead pressed against the bottom window frame, slowly becoming aware of the uncomfortable dampness in his underwear. Still groggy from his orgasm, it took him a moment to react when Hotch left the office. Spencer stared at him stunned for a moment, his mouth open and his cheeks flushed, and then he lowered his head, pressing his lips nervously. There was no explanation for that. He was sure his boss could perfectly smell the arousal in him despite the suppressants.

"Get up," Hotch ordered.

Spencer gulped and stood up. He tried to hide with his hands the stain that was already noticeable on the front of his pants, although the one behind him embarrassed him the most. Hotch stepped aside and gestured for him to enter the office. Spencer obeyed, even though he just wanted to run away.

Hotch closed the door and walked over to him. He put an arm around his waist and pressed their bodies together. Hotch buried his face in his neck and Reid tilted his head immediately like an instinctive act, giving him space.

"Alph- Ho-Hotch?" he asked confused.

The Alpha took a deep breath and caressed his skin with his lips.

"You smell like paradise," his voice sounded husky and deep.

"What?"

Hotch pulled his face away from his neck and went up, kissing his ear and smelling his silky hair.

"By now the suppressants have almost worn off," he whispered. "You should be careful, if you go out like this you'll be a potential victim."

Spencer sighed feeling Hotch breath. His legs were shaking. He was so nervous, so shocked, so overwhelmed by the scent of the Alpha. What was happening? His boss had never behaved like that, never shown the slightest interest in him, or approached any other omega like that. He didn't seem his usual self at all, and Spencer didn't know how to act.

The Alpha slid a hand down his perfect ass and pressed between his buttocks. Spencer moaned and pushed his hips against Hotch. He could even hear the dampness of his slick, and it dripped even more.

"You're so wet for me. I'm honored, I've never seen you get like this."

The young man felt a vibration in Hotch's chest, a commanding growl, and he wanted with all his might to undress and present himself to the Alpha. It was difficult for him to resist despite the great self-control he had. He was right, he had never feel like that with any Alpha, although he was not surprised to have that reaction with his boss.

"Hotch, what are you- huh?!" He was startled when Hotch tugged at his pants, pulling his underwear down as well. Hotch turned him around and slid his erection between his legs. "Nnh! H-Hotch?"

He was beginning to worry. He wouldn't be thinking of having sex with him, would he? And how could he still be hard? Furthermore, the knot was still swollen. It was impossible for him to try to penetrate the omega with that.

"Easy, just hold on," Hotch whispered, wrapping an arm around his chest to keep the omega against him.

He began to move his hips, thrusting slowly between his legs. Now Spencer could really feel it, its hardness and warmth rubbing his balls, the knot slapping against his hole and his thighs, all coated in his own slick. He felt so good, in the Alpha's arms, against his broad chest, enveloped in his scent, feeling that his cock could lift him into the air on its own. He stopped thinking or just arousal rendered his mind useless. He clung to the arms that held him and began to moan, his hips moving to meet the Alpha's thrusts. He was hard again, but he didn't care about his cocklet, he just wanted to satisfy his ass, he wanted Hotch to enter him, to be filled, knotted and marked.

That didn't happen. Hotch hugged him tightly and came between his legs with a deep groan as he too came over the desk in front of them and squeezed his thighs in the most intense orgasm he had ever experienced. They stood still for a moment, regaining control of their bodies. Spencer could feel the hot cum from the Alpha sliding down his thighs along with his slick. It was an uncomfortable feeling, but he couldn't help but think that it must be inside him, impregnating him. His logical part didn't really want it, but his omega side craved it.

Hotch slowly released Reid's body, making sure he could stay upright, and pulled a box of tissues from his desk drawer. While the young man still remained stunned, his boss cleaned him up, trying to avoid staring at that delicious ass. Hotch pulled up his pants and arranged his clothes a little. He turned his back on him and began cleaning the desk.

"I'll drive you home," he said, without turning to look at him.

"Ah... N-no... I can go by..." No, he couldn't go by train by now, he had missed the last one, but he didn't want to go with his boss in the car at that moment.

"There are no more trains."

"I'll take a taxi," he replied.

"I can-"

"Thanks, but I'll take a taxi." He hurried out of the office, if Hotch insisted he would end up giving in.

In the everlasting hour-long drive, Spencer had time to collect his thoughts, to take in what had happened. He was mad at Hotch. He had never imagined that he was that kind of man, capable of cheating on his wife, of assaulting an omega, a teammate, and doing that to him without even asking him first. It is true that he had not refused at any time or tried to stop him, but perhaps he would have done it with a somewhat clearer mind, not right after he had masturbated. But he was not angry because Hotch had done it to him, but because he was capable of doing it. This was not the man he knew (or thought he knew) or the one he trusted to the point of putting his life in his hands or shooting someone for him. There had to be some reason for that, after so many years working together he couldn't know him so little. He wasn't sure if he could keep working with him if he lost all respect for him as a man, and that was what hurt him the most.

He could barely sleep. He couldn't get what had happened out of his head. He would sometimes get furious and walk around the apartment; other times his body began to heat up as he remembered the feeling of Hotch's body against his, of his dick thrusting against him, of his intense smell enveloping him... and he ended up under the cold water of the shower. It was almost mental torture.

"Hey, pretty boy, are you okay? You look awful," Morgan asked him when he got to work.

"I'm fine, I haven't slept much."

"Reading until dawn again?"

"Yeah..." Luckily, the double dose of suppressants kept others from sensing the smell of concern and anxiety he gave off.

"Spence, Hotch wants to see you," J.J. informed him as she left the office.

"Are you in trouble?" Morgan mocked.

Spencer didn't answer, he just shrugged and headed over to his boss' office after putting the backpack on his desk. He knocked on the door and walked in with his head down. He didn't want to look at him, at that moment he was in furious mode and he didn't know how much he could control himself if he looked him in the face.

"Sit down."

Reid obeyed and sat with his arms crossed in front of his chest in a defensive posture, still not looking at his face. Hotch got a little annoyed, but let it go.

"First of all I want to apologize for yesterday, I didn't want to make it so rude-"

"Why did you do it?!" he burst. "You are married and you are my boss. What the hell were you thinking? You didn't even look like yourself. Would you have stopped if I asked you to?"

"Reid-"

"And who's ever thought to masturbate in the office? Anyone could have caught you. What would you have done if it hadn't been me?"

"Reid."

His powerful tone left him speechless, the omega froze as if he had been physically immobilized. Spencer pursed his lips and huddled in his seat.

"I want to apologize for what happened yesterday, I didn't mean to do it that way. You can consider that I've been unfaithful to my wife if you want. And that she's had an affair for months doesn't justify it, but I've already contacted the lawyer to begin the divorce proceedings. Yesterday I wanted to talk to you about it, but... I got distracted. I can get an express divorce if I intend to mate with an omega and for that I need you to confirm it in the application."

"Do you want me to lie?" Spencer asked confused.

"Of course not," he replied with a frown. "I intend to mate with you when the divorce is official."

"Wh-wh-..." Spencer was completely stunned by everything he had said and the clinical tone in which he had said it, as if he was speaking nothing more than a routine procedure. "You haven't even asked me! And why me? I'm sure there'll be hundreds of omegas wanting to mate with an Alpha like you. And I don't want to mate just to make your divorce easier, it's too important to do it for something so trivial."

"I think you haven't understood me. I am not going to mate with you to get divorced, I am divorcing to mate with you. I wouldn't do it with anyone else. And I have not consulted you because I already know what your feelings are so I didn't consider it necessary."

"You already know...?" Impossible, impossible, impossible.

"Yes, I've seen you without suppressants enough times to know that you're in love with me, probably since you joined the BAU, and the feeling is mutual. I've considered divorce many times, but the situation has never been right and I felt that I had an obligation to Haley since she's the mother of my son, that I should try to make our marriage work. However, since that has not been possible, I find no reason not to take you as my omega once the divorce is effective."

He said it as if it were something logical and obvious, as if there was no option to reply. Reid was speechless, it was difficult for him to assimilate everything he had said, he felt as if Hotch had talked it in a foreign language, they were words without meaning. The only thing clear to him was that he was going to divorce Haley and that that bi- woman had been cheating on him. How was that even possible? She was married to a thoroughbred Alpha, the best man and father he had ever known. Even without the instincts of an omega, she must have been aware of the kind of husband she had. And she was capable of cheating on him? She had no forgiveness. The feeling is mutual. When that phrase made its way into his mind, everything else faded away. Was that what he thought it was?

"Are you in love with me?" he asked Hotch directly. He needed to clarify it immediately.

"I think that's what I said," he replied calmly.

"Ah... Ah…" He didn't know what to say, he felt his face start to turn red.

That couldn't be true, an Alpha like his boss would never be interested in an omega like him. He had so many other, much better options that it was ridiculous for the Alpha to fall in love with him. But despite all this, he was immeasurably happy. Hotch was right, it had been love at first sight, ever since Gideon introduced them. He smelled of books, fireplace and home, it was the most pleasant smell he had ever sensed. Now he was used to it, but at first his body wouldn't stop reacting.

"I'd like you to continue working here after we mate. I know you can do it, although I'll make sure I don't send you to dangerous places. However that's only your decision, I'll be fine if you stay at home looking after Jack or look for a more relaxed job."

Reid was barely able to understand him. He kept mulling over the fact that his boss was in love with him. Seriously?! And now that? What did he have to do? Hotch seemed to have it all planned, he just had to accept and even that Hotch already took for granted.

"Um... I..." He was completely blank, he didn't know what to do or what to say.

"Go back to the bullpen, after work we can talk more about this if you want. And I'd rather the others didn't know about it yet, although I'm not sure you can hide it."

Spencer stared at him for a moment. Hotch looked as calm and cold as ever, not even his scent seemed altered. It was hard to believe him because no one could remain so impassive while confessing to the person he loved and 'asking' him to be his omega. He got up from his chair and came out of the office almost like a zombie and sat at his table.

"Reid, are you okay?" Prentiss asked him.

He didn't even turn to look at her, he just nodded his head tightly.

"Hey, are you really okay?" Morgan came closer as well. "Has something happened with Hotch?"

"N-no, I'm fine," he replied, pulling out his tablet so he could pretend he was doing something.

His teammates looked at each other with a frown. Morgan didn't hesitate, he went directly to his boss' office.

"Hey, Hotch, did something happen with Reid? Is there a problem?"

"There is no problem."

"Seriously, what happened? Reid came out of your office acting weird."

"Derek, it's nothing you should know, at least for now. It's a personal matter, when I consider it appropriate I'll communicate it to the rest of the team. But you don't have to worry, nothing bad happens."

Morgan snorted. Telling him not to worry didn't help at all. A personal matter? What kind of affair could have left Reid in that state? Not convinced by his answer, Morgan left the office.

Shortly after that, an urgent case came to them so their much needed talk would have to wait and the omega couldn't clear things up yet. Reid tried to be professional and act as usual, but his teammates could tell that his behavior was somewhat strange, although they were all focused on the case and didn't say anything. Hotch treated him as always, another member of the Unit, except that he didn't let him go to the Unsub's arrest. He should have been upset, but he felt a little happy because he knew that Hotch wanted to protect him.

They didn't return to Quantico until the following day after two in the afternoon. They had barely put their things down on their respective desks when Haley walked into the office like a storm had struck.

"Where's that whore?!"
