A lot was going on at work. They were currently working on two different cases. In the local area. Hotch needed to split the team up. He had sent Rossi, Morgan, and Prentiss to work on one case. He, Reid, and JJ were working on the other.

Hotch and his group had finished their case. It was an open-and-shut case. Once they started to help local law enforcement it wasn't long before they had their unsub arrested and charged. Once they finished up Hotch told Red and JJ that they should step in and help Rossi's team. Their case wasn't as easy, and Rossi was happy to welcome the additional help. They had just come into the conference room where Rossi was watching a screen. Morgan and Prentiss were undercover as a couple at a local club trying to bust a drug trafficking ring. They were wearing cameras and mics so the team could see everything that was happening.

Morgan and Prentiss got into a sticky situation, and they had to get close and kiss to not blow their cover. Thankfully it worked and before long they had their case wrapped up too. When they got back to headquarters everyone started on the paperwork. JJ had seen Hotch's face when Morgan and Prentiss had to kiss. And she figured the two did not know that Hotch had seen it since he was working a different case. The squad room was empty except for JJ, Morgan, and Prentiss and JJ looked at the two of them.

"Look. I know it was undercover and you did what you had to do. And I don't think Hotch would say anything, but you should know. We finished our case before yours was finished and had come into the room to help Rossi and you two. Hotch… saw things." JJ said

"Did he say something?" Derek asked

"No. But his face did." JJ said

"I'll handle it," Emily said. She knew she hadn't done anything wrong. She had been doing her job and if the situation came up again she would do the same. But she knew that if the roles were reversed she might be a little jealous herself.

They finished up the paperwork and everyone headed out. Emily and Aaron were the last ones out and they both went out to their cars and drove home. They got home to an empty house. Aaron had texted Lorelai and asked her if she would take her siblings out so he and Emily could have a date night.

Lorelai didn't hesitate and she invited them over for movies and pizza with her and Spencer.

When they got inside and closed the door behind them Aaron locked it before turning to Emily and grabbing her wrists pinning them above her head against the side of the stairs.

"Do you know what seeing you kissing another man did to me?" He growled

She looked up at him. "I'm sorry sir. I know I'm yours."

He kissed her deeply. "Damn right." He said. Hotch had never known himself to be possessive. But he had never had to watch the person he was in love with kiss someone else. Regardless of if it was undercover. He broke the kiss and took her arm and led her to their bedroom closing the door behind him. "Strip." He ordered

Emily went with him. Her heart raced slightly with anticipation. When he closed the door and ordered her to strip she did so.

He watched her strip as he removed his suit jacket and threw it on the chair and removed his tie throwing it on the bed. They would need it in a bit. He unbuttoned his shirt and let it fall to the floor before he stared admiring his woman. Naked standing there waiting. He went over to her and pulled her into him. Kissing along her neck.

Emily tilted her head to give him more access. He moved towards the bed pulling her with him. "On all fours." He growled into her ear.

Emily quickly got on her hands and knees on the bed. Aaron swatted her ass.

Emily took a breath a small whimper escaping at the impact.

He removed his pants and underwear. He pulled her back a bit, so she was against the edge of the bed before he put himself inside her ass and thrusted hard.

She whimpered.

He looked down at her. "Safety check." He said after the first-time things got rough they had discussed safe words and limits and such. And when she whimpered he wanted to just be sure.

"Green." She said

Aaron continued thrusting hard. "You're mine." He growled. He swatted her ass hard watching the red handprint quickly fade away.

"Yes sir." She said

He came up her ass before pulling out and swatting her ass twice more. "I love seeing my handprint on your ass." He whispered into her ear.

She gasped when his hand connected with her butt harder than before. "I love your hand on my ass. No one else's." She said between breaths

"Stand." He ordered. "Hand behind your back."

Emily did as she was told. Aaron grabbed his tie from the bed and tied her hands behind her back.

He gently pushed her back onto the bed. He got on his knees and started to kiss down her body from her neck down to her vagina. He kissed it before licking inside slowly.

She moaned loudly when he worked his way down her body and inserted his tongue inside her. "Oh God sir." She said

Aaron took a breath and stopped licking and just blew inside her.

She moaned and lifted her hips begging for more. He pushed her hips down. "Keep your hips down." He ordered.

Emily nodded. "Yes sir."

He inserted two fingers and moved them in and around slowly.

She moaned loudly.

"Like that?" He asked

"Yes sir. You are so good at that." She said

He took his fingers out and started to kiss up her body to her neck. He nipped gently.

She whined a bit when he pulled his fingers out and moaned when he nipped at her neck.

He smirked a bit at the whine. He had her right where he wanted. Wanting him. He kissed back down her body and to her wet pussy. "You want more?" He asked

"Yes. Please sir," she begged.

He swatted her inner thigh and smirked. He inserted himself into her and thrusted slowly at first and picking up pace slowly. Till he was thrusting hard and fast.

They both reached climax together. Aaron moved so he was laying next to her. They both laid there catching their breaths.

Emily got her hands free as the tie had been done up loosely. She turned on her side facing him putting an arm over him and a head on his shoulder.

"You know that I would never have done that if it wasn't necessary right?" Emily asked

Aaron smiled. "Yes, I know. I was a bit jealous, yes, but I know undercover sometimes we have to do things we don't want to." He said

"Just using it as an excuse then?" She chuckled

"You love it." He said with a smirk

"Yes, I do." She admitted.

They stayed cuddled up to each other like that for a while before they got up and got dressed. They moved into the kitchen and started to pull leftovers out of the fridge to heat up and they talked and had dinner together.

Aaron pulled some ice cream out of the freezer and a couple of spoons and went over to the table and sat back down with Emily. They enjoyed their dessert and conversation before long heading back upstairs for a round two. They didn't get much time alone together and they were fully taking advantage of it tonight.
