They were having a team night out and they couldn't have been more excited for it. It's been a rough couple of weeks and this was the time that everyone finally got to settle down. JJ looked around the team to see that everyone was having a great time. It was funny having Elle back and with Emily, what was even funnier was that they clicked as if they have been best friends for the longest time. If JJ had to guess she would think that they have been friends since they were kids, you could even say that they act like twins, thinking in the same way and having similar talents and yet they were complete opposites. Elle was fiery and angry in some ways where Emily was calm and diplomatic. JJ and Pen would joke about them being secret siblings and that they have not told the team about their shared birth parents. JJ looked at Hotch, who surprisingly admitted to have had some issues with his now ex-wife Hailey, was laughing at something Elle said. What was more surprising was that both Hotch and Hailey seemed to be in a better place now that they were apart. She grinned as she saw Hotch lean over and pluck Elle's olive from her drink and pop it in his mouth. JJ nearly burst out in laughter when she saw the glare that Elle gave Hotch. The whole team had had money on when Hotch and Elle would admit to wanting to be with each other. JJ had a feeling that it would take some prodding and teasing from everyone but that it would happen eventually whether they liked it or not. It turned out they were right with Gideon and Rossi splitting the pot.

JJ then took in stock the rest of the team. Emily and Spence was just the cutest thing, starting from the way they started dating all the way to how they were now. It seemed to happen yesterday when Emily had been shot by an unsub with a paintball gun. She went down quick and Spence went over screaming her name, promising he would never tease her about her romance novels again or say that he was ten times more intelligent than her (as true as it was) if she would open her beautiful eyes. To say that everyone was a little surprised was an understatement (though JJ had a sneaking suspicion that Gideon knew about Spence's feelings all along.) Emily's eyes popped open in surprise and just as Spence was about to lean in to give her mouth to mouth she popped up and kissed him. To say the scene was hysterical would bring JJ to tears again. Their first date was one for the ages when it came that Derek had to take Reid shopping to get something nice to wear and buy Emily a little gift. Spence was so nervous she thought the poor boy was going to die of a heart attack.

Gideon and Rossi were a trip. Arguing about one thing and the next. The rough agent and the grandfather of the BAU were two of the most comical members of the team. What made it worst was that they were serious 99% of the time. Often quiet and keeping to themselves it made them all wonder how they got along, but at the same time it wasn't hard to see that the two would compliment each other. Both tortured by the faces of the victims they lost and the loved ones of those victims. Gideon and Rossi weren't really for the public scene but the team knew that if they were able to get one to go that the one they got would force the other to tag along. It was really a silly thing but it added to the humor of this team, and in the line of work that they had, they needed all the humor that they can get.

JJ then stared at Pen who was cuddling with her main squeeze for the past year. Kevin Lynch was really a cute little thing. Praising his hacker goddess with every chance he got. JJ had to fight the smile that came to her face when she remembered Kevin challenging Derek to duel in order to win the hand of fair Penelope. Of course Kevin didn't need to trade blows with Derek, but it was hilarious to see Derek's face in utter confusion. JJ had to say that they were utterly adorable and she couldn't wait for the ring that has been weighing down his pocket to adorn her friend's finger. JJ grinned and sighed as she looked down to her finger. Will had asked her to marry him and naturally for her son's sake she said yes. Since then her relationship with Will has only deteriorated. They've been arguing and throwing things; Will leaves her place and doesn't come back for a night to even days. It was frustrating and what was even worst was that Henry was starting to notice the lack of his father's presence.

She turned her head from those thoughts and looked to the dance floor. And there in the middle of a group of beautiful women was Derek Morgan. His body was moving with the music and grinding on two or three different woman at the same time. It was like watching sex on the dance floor and JJ couldn't stop the wish of it being her moving her body against Derek's the way those other women did. She looked back at the group and realized that she was the odd one out and when she turned to look back at Derek it was like he knew what she was thinking and he nodded her over. She initially shook her head but in the end she lost out and walked out to the dance floor to join Morgan. She gasped as he yanked her hand to bring her closer to him and pulled against his body. She naturally gripped his shoulder while his hands went around her waist. Before she knew it, Derek and her were grinding to the beat of the music and JJ's thoughts went from the dark place they were in to a lighter one. She closed her eyes for a second and when she opened them she found the whole team around them dancing.

She looked back to Morgan and grinned before leaning down and whispering in her ear, "This is your chance for a night out after all the tough cases we just went through and your sitting at the table looking like a loner." JJ grinned at his comment and just shrugged trying to ignore the shiver that went down her spine from his touch. She felt her body being moved closer to him and she inwardly groaned at being so close to him. The music changed to "Rockin' that Thing" by The Dream and her and Morgan's bodies seemed to mold together. Moving to the rhythmic beat of the song, for the first time in a while JJ was having a good time with a man since Henry was born. It was unfortunate that it was with her partner Derek and not the father of her son, Will. Though if she really thought about it, grinding with Morgan could be considered a very fortunate situation for any warm-blooded woman. She turned to have her back pressed against Derek's chest. It was like their bodies fit lock and key. She shivered again when Derek leaned forward and whispered, "See, isn't this more fun?" JJ could only nod; afraid her voice would come out in a moan.

Before JJ realized it her and Morgan had been dancing for about an hour and she was beginning to feel flushed. As if reading her mind, Derek Morgan moved from behind her and pulled her to the table. He ordered the both of them some drinks and helped JJ into the booth before sliding in next to her. He leaned in close to her and said in her ear, "What's up with you tonight girl? You've been out of it. Is everything okay?"

JJ could only nod as once again Derek's voice had an effect on her body. "It's nothing Derek, I'm good. Just a little tired. You know that Henry can be a riot but I love my baby." She purposely left out any information on Will, hoping Derek wouldn't ask. When every one first met Will, they encouraged her to live her life with him, but as soon as Henry was born, things began to change. Will was pushing for her to go back home with him, to quit her job and be a stay at home mom, but she loved her job and the people she worked with and she knew that if she decided to leave, they would support her but she wanted to stay and that was what she was going to do. Since they had that argument, her and Will have been at ends and she had a feeling that their relationship would not last. The thing was Will was the father of her child and with the values she was raised with, she had to try and keep this family together.

"What about Will, isn't he helping you out?" Derek asked with concern coloring his voice. JJ inwardly groaned at the question and leaned her head back. She looked to Derek, begging with her eyes for him to let it go. Understanding her silent plea, he leaned over again and said, "I'll let this go for now, but we will talk about this some time." Derek winked at her and JJ sighed in relief. She leaned her head on his shoulder and closed her eyes, allowing the music to wash over her.

A Couple Hours Later:

The Pub was closing up and the team was the last to leave. They were fairly drunk and decided that they would double up in cabs. Spence was with Em, Hotch with Elle, Pen and Ryan, Gideon and Rossi, and that left JJ with Derek. JJ was laughing and giggling as she leaned heavily on the muscular Derek Morgan. She reveled in the feeling of his arms wrapped around her as they climbed into the back of a cab. They laughed and joked in the back of the cab as they headed to JJ's house. After the pulled up to the curb, JJ opened the door and climbed out. She turned to face Derek before he could close back the door and asked him something she would not ask him in her right mind, "Hey you want to come in?"

Derek hesitated, not sure if this would be a good idea, but the disgruntled cabby rushed his decision, "Either you get out of the car or you close the damn door and I take you where you're supposed to go!" Derek winced as he climbed out of the car and followed JJ to the front door.

Derek grabbed JJ's hand and pulled her back with worry in his eyes. "Isn't Will home?" JJ only shook her head, before grabbing his hand and leading him to the front door. She opened the door and led Derek into the house. Henry was with her mother, so he wasn't at the house. JJ continued to lead Derek to the end of the hallway, where her bedroom was. Derek pulled back from JJ again and stopped, "JJ, what's going on?"

"Shhh!" She giggled to him. She then yanked him again into her room. Derek followed her, shaking his head and chuckling. He gasped as JJ jerked him closer to her. He gave her a confused look, but JJ just playfully shook her head. Derek was strongly fighting the urge to kiss JJ, but with his judgment clouded by alcohol, Derek's body started moving before he could think to stop. Like a shock his lips connected with hers and he sighed in relief when she kissed him back. He knew it was wrong, they were drunk, they were in her bedroom, she had a child, and she had a fiancé. This was wrong, so wrong, but right now in this moment he didn't care and it felt so right.

Derek pulled out of the kiss and jerked himself away from JJ. "I'm so sorry JJ…" His words were cut off as JJ's lips reattached themselves to Derek's lips. Before he knew it, they fell to the bed and…

The Next Morning:

JJ woke to an arm wrapped around her and she paused thinking that it couldn't be Will holding her so securely. She turned and gasped as she saw Derek Morgan was the man holding her so tightly. She groaned thinking that her and Derek did something that they weren't supposed to, but as much as she thought about it, she couldn't muster any guilt. She felt warm and protected and very relaxed. It wasn't an ideal situation, but it just didn't seem that bad to her. Here she was in bed with one of her colleagues and she couldn't find one problem with it. Maybe because she has always wanted to sleep with Derek Morgan, who wouldn't, or maybe because as much as she did not want to think it, it felt right to have him here in bed with her; like he belonged. This was bad, so bad and what was worst was that she was making no effort to leave the bed at all. She just continued to snuggle in Derek's warmth for no apparent reason. She wished she remembered what happened last night, the only thing she knew was the ache in between her legs along with the continued hum her body felt from sleeping with Derek and that obviously signaled that her body enjoyed itself immensely. She started to giggle at her thoughts btu she froze when she heard Derek groan.

"JJ, you want to keep it down. Some of us are trying to sleep." JJ continued to hold her breath and she allowed Derek's words to sink into his subconscious. Finally Derek's eyes popped open and he gasped. JJ felt a little hurt as he jumped from the bed, but what did she expect, for him to be happy that he woke up in bed with his engaged partner. Nope. This was what she should've expected, but it didn't make it hurt any less. "JJ…" She jumped as she felt his hand on her shoulder, she turned to find him in the bed next to her again and sitting close to her as if waiting for something. As if waking up to your partner wasn't bad enough, the overwhelming urge to cry taking over you was just adding to her agony. JJ broke down and began to cry, feeling herself being pulled into the body of her partner turned lover for one night, Derek Morgan.
