A/N Thank you everyone for your reviews and ideas! This idea I got from Nix1978 and I know some other's wanted me to show Emily's experience with women!

So yes, this might be a little different and it was really hard to write!

I also had a conversation between the girls in the beginning but somehow a part of the story disappeared and I couldn't remember what they talked about;)

I'm done rambling. Now please enjoy.

Chapter 4

It was Garcia who had decided that a girl's night out was fitting the evening after they had gotten back from the case. Earlier that day they had been doing paperwork and Hotch had told them to stay home tomorrow so they could get a day of rest.

The first round of drinks was on Garcia. She ordered a strawberry shot for each of them and they put it down quickly. The second one Emily decided to take and later by the fourth one they all started to get a little drunk.

Neither JJ or Garcia were single at the moment so they had no intention of getting the men's attention. Emily knew a couple of guys looked her way, but she wouldn't take them up on any offers because tonight she wanted to spend with her friends. Besides, if she would feel really horny later that night she could just pay Derek a visit. Even if she was still mad at him.

"Emily?" a voice she knew wasn't JJ or Garcia's said behind her, bringing her out of her thoughts.

She turned around and knew the shock on her face was showing miles away. And she was shocked. Never in a million years would she have thought she would meet her here.

"Amy? Is that really you?" Emily's jaw was still on the ground and she couldn't get it closed.

A full minute she was like that, eyes wide and mouth open, before she realized that she looked stupid and had to do something. She stood up and hugged the two years younger brunette and was happy to get the hug returned.

"Thought you would sit there staring at me for the rest of the night," Amy said, jokingly.

"I was just surprised, that's all. I mean I haven't seen you since college," Emily admitted. "Oh, this is Jennifer and Penelope."

She gestured to the women sitting next to her, who had been very curious to whom this mysterious brunette was.

"Nice to meet you guys," Amy said, giving them a smile before turning back to Emily. "Can I buy you a drink just to catch up on things?" She winked at Emily and a blush spread upon her cheeks, an effect this woman always had on her.

She looked to her friends as if to ask for permission and they immediately nodded their heads. Amy took the older woman too a booth not too far away from JJ and Garcia, but far enough to get some privacy.

JJ turned to Garcia as soon as they were out of earshot. "Oh my God! Did you see that?

"See what?" Garcia asked.

"Emily and Amy! I didn't know she was gay! Don't tell me you knew."
Garcia couldn't help but to burst out in laughter, "Emily is not gay! Not the least!"

"I'm not sure about that. Have you ever seen her in a relationship? This explains so much! The way she refused to call Rawson. Of course she wouldn't because he's not a woman!" JJ rambled on.

"How much have you had?" Garcia asked, gesturing to her glass. "There's no way she is gay. Maybe bisexual, but not gay, nuh uh."

JJ narrowed her eyes. "You know something." she stated more than asked.

"I don't know what you're talking about." Garcia turned towards the bar in a nonchalant manor.

"Yes you do! Come on spill it," JJ said, tugging on Garcia's arm to turn her around.

"Okay, but only because it's too good gossip to not spil," Garcia said, glancing at Emily. "My chocolate thunder and that Raven haired beauty over there have been doing the nasty."

JJ's eyes bulged out. "No way, they wouldn't do that. It would risk everything." she shook her head.

"Oh yes they would. I've seen proof of it too," Garcia smirked over her glass.

"What? You caught them?"

Garcia chuckled. "No," she said, putting her glass down and leaning in closer. "They did it in the gym and was worried about the surveillance."

JJ shook his head and brought her drink up to her lips. "No way. They would never do anything in the public like that. They..." JJ put the drink down as her eyes widened. "...did it on the jet! Oh my God!"

"What?" Garcia got curious.

"Emily felt bad after the case and both went into the bathroom. I don't know how long they'd been there before I woke up, but after they were there for ten minutes. Derek said he was comforting Emily and I believed him." She narrowed her eyes. "Those naughty..." She shook her head.

"Wow, first in the Gym and then on the jet. What's next? The bullpen?" Garcia took a sip of her drink.

"Unless they've already done that," JJ said, making Garcia almost spit out her drink.

JJ laughed loudly at her friend.

"What's so funny?" Came their friend's voice behind them.

JJ turned around quickly to see both Emily and Amy standing there, but this time she knew Emily was into guys. Too. "Oh, nothing at all. Garcia is just being Garcia."

"Hey!" Garcia said, slapping JJ playfully on the shoulder.

"That's a good thing," Emily assured the colorful blonde. "Anyways, me and Amy haven't seen each other in like fifteen years so we're gonna head home now if that's okay."

"Oh yeah, you do that," JJ said with a smirk. "See you on Wednesday."

"Yes, see you!" Emily hurriedly said, a little alarmed by the knowing smirk on JJ's face.

Did she know about Emily's college life? Did she know that she had dated Amy for more than a year? She knew something, that was for sure. Emily took Amy's hand and together they left through the crowd.

JJ turned to Garcia with the same smirk on her face. "She is definitely playing for both teams."

Amy's hands had been all over Emily on the way home in the cab and frankly, Emily had liked it. Her hands were pretty skilled which Emily learnt years ago and was finally able to relive for only one night, or two as she had promised. She had made sure this was only going to be sex and that there was no chance of them getting back together. Amy was fine with it. She was a full lesbian. Unlike Emily, she hadn't been with a man since they were together, and Emily hadn't been with a woman since.
She realized she'd missed it, especially now when Amy had her hand under Emily's dress, making sure Emily was getting wet. On the way back to her apartment Emily had texted Derek to come to her place and join her for her date with the hot tub on her roof.

She'd talked it over with Amy if he could join and she'd agreed with the condition that he couldn't fuck her and that she would have Emily to herself the next night. Emily quickly agreed to that condition. She knew what Amy thought of men and would rather drop dead than to let one of them penetrate her. With Emily's plot for revenge, Derek wouldn't do that anyways. He might not even fuck her either, but she doubted she could make that promise.

Arriving home, both girls ran up all sets of stairs to first Emily's apartment to get wine and three glasses. Emily locked the door behind her and together they walked up the last sets of stairs to the rooftop, passing the gym of the building and coming out in the cool air. To the left was a pool and to the right was the hot tub which she was sure no one would use this late. Amy was the first one to drop out of her dress, showing her perfectly full breasts and letting Emily know that the younger woman hadn't worn panties that evening. Emily admired her body before she pulled of her own dress, shimmied out of her panties and approached Amy.

Amy looked Emily up and down. "Damn, you look even better than I remember," Amy said, her eyes turning dark.

She took Emily's hand as they walked into the hot water. Emily turned it on and the bubbles started. Amy started kissing Emily, straddling her body so that Amy's clit rubbed against Emily's. Her tongue ran over the older woman's lips, happy when Emily opened them slightly and gave Amy permission to deepen the kiss.

"You're so beautiful," Amy panted.

Emily smiled against the younger woman's lips.

"God, you always knew how to get me off," Emily said, arching her back to get closer to her ex.

Amy moved her hand between their bodies and started stroking Emily who threw her head back.

"Oh God," she gasped. "As much as I want you to continue, Derek will arrive any minute now."

"So let him catch us in the act," Amy said with a smirk.
Emily giggled. "Just imagine his face."

"He would want to jump you and I wouldn't blame him." Amy said as she inserted two fingers, earning a deep moan from Emily.

"Seriously, we should stop. I promise we can continue this later. I need to continue this."

Amy pulled away. "As you wish, babe," she said and turned to pour the wine. "Hun, I think you forgot the wine opener."

"Really? And you don't happen to know how to open it without one? Like a party trick?"

Amy chuckled. "No, but I do have two legs and would be happy to get it."

Emily gave her a hard kiss. "You're an angel!" Amy got up from the hot tub and took Emily's keys. Emily couldn't help but let her eyes roam over the beautiful woman's body.

"Be right back," she said, grabbing a towel as she walked inside again.

Emily closed her eyes and leaned back, letting herself relax in the hot water.

"Can I join you?" Emily suddenly heard, making her jump out of her place.

Usually she wasn't this easily scared, but the added alcohol made her different. She wondered if she would even considered bringing Amy home if she hadn't been intoxicated. Probably.

"Be my guest," Emily said without opening her eyes.

She could hear the sound of clothes dropping to the floor and the water shifting around her. Emily smirked to herself, still with eyes closed and leaned back. She moved her hand slowly up her body and let out a soft moan to tease Derek.

"You're starting without me," he said and Emily could hear the pout.

She could feel him moving closer as he brushed against her thigh. For another minute she kept her eyes closed and let Derek touch her just a little, but when he came close to her center she moved away.

"Hey, what are you doing?" Derek almost whined.

Emily knew he was already turned on since his hard-on had pressed against her thigh.

Without answering she leaned back again and closed her eyes. Derek furrowed his eyebrows. This was a whole new level of weird. Why was she acting this way? What had he done? Wasn't she the one inviting him over?

"Em, talk to me?"

He almost sounded sincere, a tone Emily hadn't expected, but she didn't care.

"He's here!" another female voice startled Derek. He turned around and was met by the naked body of another brunette woman.

This time Emily opened her eyes and smiled widely. "Took you long enough, babe."

Babe? Derek looked between the two women and watched as the stranger walked into the hot tub and sat just next to Emily. Hadn't he had a dream like this once? Maybe a long time ago, but he knew two naked women alone with him in a hot tub was a dream come true.

This time Emily really looked at him with that dark look telling him exactly what she wanted, but he was surprised that instead of making a pass at him, she started kissing the other woman. The kiss wasn't just a small peck on the lips. No, they were deepening the kiss, tongues exploring each other's mouths, hands starting to roam the other one's body.

Derek's eyes had already widened at the sight. Never in his life had he imagined his colleague like this. Kissing and on her way to fucking another woman. In front of him too. In front of any man. And he was getting turned on so fucking much. His member was rock hard and he just wanted to join them right now, but he couldn't stop staring at them. They made no gesture of inviting him in either.

Emily shifted slightly and let the other woman straddle her. A load moan escaped Emily's lips and Derek's member twitched at the sound. Fuck this was sexy. But he needed release. Carefully, he scooted over towards the women, but as soon as he tried to touch Emily, he was pushes away.

"Stay back. You're just gonna watch," Emily panted.

What? As much as he loved this he couldn't just watch. He couldn't just watch this other woman pleasure Emily the way only he could before.

"But Em..."

"God, Amy," Emily's loud moan interrupted him as Amy inserted two fingers. "Mmm fuck me."

Derek saw the woman, he now knew as Amy, move her arm quickly back and forth and Emily moaned loudly.

Emily knew she was close. Her walls were already clenching around Amy's fingers. And she knew that after she did explode, Amy would begin round two and she was not going to say no to that.

Through half closed eyes she glanced to Derek who's eyes were dark in desire. She knew he had to work hard to hold back; she could tell by the way he was shifting in his seat. Emily smirked to herself. Yes, this would probably teach him to never mess with her again.

As soon as that thought had left her, Amy started pumping harder and circled her clit with the thumb until Emily finally was brought over the edge. Toes curling. Walls clenching. Fluids dripping out and mixing with the water. And a loud moan in ecstasy.

Derek watched his lover, if he could call her that at this moment, in amazement as she came. Man, that was hot. Almost as hot as making her come himself. But it didn't give him the same release. Sure, if he let go this hot tub would be mixed with his cum too, but that would be embarrassing. No, he couldn't let go until he was inside of Emily. Or Amy. Amy was fine too if that's what Emily wanted. Right now he wondered what Emily's plan was. Had she invited him in just to torture him or was he ever going to get the permission to... Oh fuck!

Amy patted for Emily to hop up and sit on the edge of the hot tub and Emily obliged, sending one look Derek's way at the same time.

Derek narrowed his eyes at her. He knew what this was. She's getting back at him for something. If only he could figure out what. A moan from Emily hindered him from delving more into those thoughts.

Amy was between Emily's legs circling Emily's clit with her tongue. Emily threw her head back, closing her legs to keep Amy's head in place and arching her back to get closer to the woman.

Amy moved her tongue between Emily's glistening folds and dipped inside as deep as she could get.

Amy had always been known to have a pretty long tongue and her most famous party trick was to touch her nose with her tongue. Or the trick Emily knew: making a woman come ten times during one night. If Emily would've let her that probably would've happened tonight too, but she knew she'd want Derek soon. Maybe tomorrow night as she had promised to be alone with Amy then.

Amy moved her hands to play with Emily's breasts, kneading them and pinching her hardened nipples at the same time as she sucked on Emily's folds and clit. Emily placed her hands on Amy's head and pushed her closer against her cunt.

Derek found himself wanting to watch closer. He'd never been that close to her cunt and boy did he want to taste it too. Slowly, he moved himself closer. He wouldn't touch her with the risk of being shoved away. Somehow it didn't feel wrong to get this close and look. That's what Emily wanted him to.

This time Emily didn't bother to look at Derek. She wanted to smirk at him, but what Amy was doing to his body made her lose all focus. Amy was fucking her with her tongue, going in and out at a fast pace as her nose brushed against Emily's clit. And Emily moaned. She just couldn't help all the sounds of pleasure that escaped her every time Amy entered her.

Derek gulped. No, he wouldn't be able to hold it in for much longer. If she didn't take care of him soon he would have to do it by himself.

"Fuck Amy! I'm gonna cum all over your face," Emily panted.

"Go ahead, babe, I've missed your juices," Amy said.

Derek's eyes widened. Missed? Had Emily been with this woman before? Had Emily been with a lot of women before? His mind kept wandering away, imagining Emily writhing under a bunch of other women who were all fucking her.

Derek shook his head to get the mental images out.

Emily's walls started clenching around Amy's tongue and Amy continued the exact same way until Emily reached her climax, throwing her head back and pushing Amy closer to make it last longer. And it did. By the time it was over, Emily was exhausted and ready to go to bed. Possibly with one hot hunk who sat close to Emily, staring at her in amazement.

"She's all yours," Amy suddenly said.

"What?" Derek asked glancing between the women.

"You can fuck her now," Amy said as if he was stupid.

This was the moment he had been waiting for, but suddenly it just all felt so... Wrong. Like Emily was just an object they could use. But she wasn't. She was so much more than that. So what should he do? He's cock was asking for him to do her, but his heart... Fuck! He was falling for her. Hard. Did he really have to choose this exact moment to realize that? Especially when it was pretty clear Emily didn't feel the same.

She looked already exhausted, but her legs were spread widely apart, inviting him in.

"What are you waiting for?" Amy asked, raising her eyebrows. "You're not man enough?"

Derek glared at the woman. God he hated her. Why would Emily ever be with her again? After a quick look at Emily, he might've understood why. The pleasure.

"Derek, I swear to God..." she panted as she looked at him. "Please, I need you."

Derek didn't need more encouragement. Hearing those words from Emily stirred something in him and he quickly lined up in front of her, brushing his stiff member over her entrance, only dipping inside with the head.

"Derek, just fuck me! Please just fuck me!" Emily started begging and Derek smirked.

He pulled Emily closer so that she was on the edge of falling into the hot water and without another warning he thrust into her, making Emily scream.

This time he didn't start slow. Instead he went quickly in and out, going deeper with every thrust.

They faintly heard Amy snorting behind them. "This is disgusting. I'm out of here."

The water shifted a little as the woman got out of the hot tub, but it was only to Derek and Emily's favor. Derek leaned into Emily and started kissing her, soon moving his mouth down her neck and to two full breasts that was waiting for his attention.

"Babe, I'm leaving now," Amy told Emily and gave her a kiss that Emily didn't care to return. "See you tomorrow."

"Uh huh," Emily moaned. "See you."

Derek pulled out almost completely before pounding into her again. He hit all the right spots every time and Emily let him know that.

Derek's hand moved around Emily's body to firmly grip her ass and pull her closer. Her legs was now on Derek's shoulders as he continued to ram into her.

Their climaxes started to build up. Or his had already been so close, but he'd tried his hardest to hold it back. He wanted to be drawn over the edge with the feeling of Emily's walls clenching around his cock and as they climaxed she would milk him of every single drop.

She was close now. The tickling feeling was nearing her stomach and her walls were making it harder for Derek to keep up the speed.

"Oh God!" Emily moaned as she got closer and closer to her climax.

Her third orgasm for the night finally exploded, taking Derek with her and letting both exhausted bodies sink into the water.

"Was that really necessary?" Derek asked as she held Emily and both had had time to catch their breaths.

"What?" Emily was confused.

"Amy," Derek looked at her and expected a smirk, but it never came.

"I used to date her back in college," Emily admitted instead. "I ran into her tonight and thought that she was the perfect revenge on you."

"Revenge for what?"

"Telling JJ I was crying. I know it sounds stupid, but I just hated when you made me sound so weak," Emily said truthfully.

"I'm sorry, Em. I didn't think it was that big of a deal," Derek said, placing a kiss on Emily's head. So what's the story about this chick anyways?"

Emily was quietly thinking of a good answer, but the ones she came up with, Derek wouldn't want to hear. And she wouldn't want to tell. "I'll save that story for another time. Right now we should get out of here and go to bed."

Emily pushed Derek away and got out of the water quickly so he wouldn't push the question further.

"Of course," Derek said and followed her up. "I don't think anyone would want to be in that hot tub until it's all clean water." Derek chuckled.

Emily smirked and glanced from the hot tub to Derek. "Eh, what they don't know won't kill them."

A/N That's it folks. I know Emily seems like a bitch and yes she might be when it comes to sex, in this story. There is a story behind it of course!

JJ knows the truth now which some people wanted. I think I will let her confront Emily in her own little way!

And Derek has started to develop feelings. That's nice. Maybe there will be something more than sex after all. Or what do you say? What do you want to see in the following chapters?

Please review! Even if you hated this chapter, tell me! I'm looking to improve:)
