Emily was feeling extremely hot. There was a beam of sunlight coming through the window falling straight on her face. She was lying on her side facing the source of heat and light. She turned on her back and felt the sheet which was covering her body slide of her. The air hit her chest, stomach. She opened her eyes slowly and saw that the white cover was still over her lower abdomen and legs. Closing her eyes again Emily left the feeling of contentment run through her. Nothing felt odd though there was surely something strange. She opened her eyes again and saw a room where she had awaken many times. She was naked but that had happened before as well, so it wasn't a concern either. But had she ever awoken in that room naked? Wait! She looked to the side and hello… Nice… There he was; lying on his back; the sheet was covering only his hip. She smiled and licked her lips. Looking up at his face Prentiss saw that he was still sleeping. Might as well enjoy the view before he wakes up… She sat in the bed abruptly; her expression thoughtful but there was a hint of a smile as well.

Reid opened his eyes at the movement. Finally Emily had woken up! He wasn't really sure what he should do after last night… Why had he let this happen? What was she doing now, just sitting there?... looking at his- Oh great! Now he was going to get hard again. He closed his eyes and took a deep breath, not that it would help anybody.

Prentiss looked up at his face once again; still sleeping - good. But what now? She let her gaze observe his body; his nakedness was making her think dirty. She wanted to reach down and touch him. Even though she had spent many nights with him, in his bed, in her bed; even though she had masturbated in front of him and she had waken up with his hardness between her legs and she had taken a shower with him, she still hadn't touched him with her hands, hadn't tasted him in her mouth; and she wanted that, really wanted that.

Reid reopened his eyes. Now what was she doing? Reaching towards his- ?

"Emily?" he pushed himself up on his hands.

"Spence, you're awake! I didn't mean to-" she babbled.

"It's OK." He told her, now in a sitting position.

"You are naked." She stated all of a sudden.

Reid frowned a bit in confusion, "You are too." He said while looking at her body.

"Yeah," she chuckled a little. "Um," she started.

"Shower?" he suggested.

"Shower. Good." Emily smiled sort of shyly and stood up; she found a towel and walked out of the bedroom. The bag she had brought last night was next to the front door. She grabbed it and walked to the bathroom.

Oh My God! She had sex with Dr. Spencer Reid! Oh. My God! And it was WOW! She wasn't feeling the insecurity from earlier. It didn't feel like a fuck for her and she really hoped it wasn't just a fuck for Reid too. He had run away from her apartment, he'd told her that they shouldn't do this, he had agreed to her request to stay with her for the night… she didn't really think the night would go like this.

Why had he walked away from her? That was stupid. God, for a genius Reid sometimes felt a bit dull. Emily would never be just a fuck for him, no matter how much he wanted sex. She is such a wonderful and beautiful and smart woman after all.

When Emily walked out of the bathroom and into the bedroom there was no tension between the two of them at all. She had smiled and sat next to Reid on the bed. He had reached to her and put his hand gently on her cheek pulling her to him and kissing her softly. Then she had proceeded clothing and he had gone to the bathroom for a shower.

After that they had breakfast and spent the day just like a normal couple: laughing and enjoying the company of each other.

On the next day before work they met up with Morgan to fill him in on what had happened between them. And Derek Morgan had been grinning like a teenage boy about to walk into a striptease club for the first time.

Once inside the bullpen the BAU members started their work. Reid was done with his report and went to see his friend in his office.

Morgan was still writing his report but dropped the pen as soon as Spence walked in.

"How's it going, Pretty Boy?" Derek smiled widely, "Prentiss was worth it, no?"

"This happens every time. I see a pretty girl and I want to make her mine." Reid told him.

"Those are lyrics from a song." Morgan frowned.

"What?" Reid asked confused.

"What are you boys talking about?" asked JJ who walked up to them from Garcia's office.

"Uh, nothing." Spence looked at the file in front of him even though it wasn't his and it was upside down as it was facing Morgan who was on the other side of the desk.

"Aaalright." JJ smiled, "Come on. Hotch wants us in the conference room." And with that JJ was out of sight.

"Ah, not again!" sighed the older man and walked from behind his desk and towards the door.

"Just to let you know," Reid started silently, "Emily is totally worth it!"

The two men walked into the conference room trying to suppress their laughter which Prentiss noticed and glared at them with half-closed eyes.

"Ok." Garcia started the briefing. "We've got a new case, not too icky but it still makes my blood run cold. Here are the victims: Jenna Smith, Sarah Jones and Amy Whitestone." The women appeared on the monitor behind her. "All three strangled to death while sexually abused." Garcia finished and sat on her chair.

"The victims were found in their homes. All three were living alone here in Virginia. There are no signs of struggle." Added Hotch.

"This means the women knew the killer and let him in." Morgan stated.

"And the pathologist has identified that the intercourse was by mutual consent." Said Penelope. That sort of shocked the profilers. "A-and their friends claim that none of them had an ongoing relationship."

"Why are they calling us so late?" Rossi asked.

"The local detective though he had things under control but after the third body he decided he needed help." Hotch explained.

Reid was looking at the files and clearly had something on his mind.

"What are you thinking, Spence?" asked JJ.

"What if the victims were into that kind of sexual behaviour? Breath control is very common nowadays between partners in all kinds of sexual relationship. The idea is to intentionally reduce the amount of oxygen to the brain during sexual stimulation in order to heighten the received pleasure from the orgasm. It's generally achieved by smothering or strangling by grabbing the neck of the partner. This also gives a great sense of control to the strangling partner and a mental release to the strangled partner." Reid explained.

"So are you saying that they might have wanted this initially as the unsub has earned their trust?" asked Prentiss.

"Not exactly. … I mean there's nothing that suggests otherwise but those kinds of relationships don't just happen. In most cases the partners have known each other for a long time and have absolute trust in one another."

"Reid is right. We need to look into the common acquaintances of the victims." Said Hotch.

"On it." Garcia started typing on her laptop.

"Look for anybody the three of them know." Added Rossi. Garcia nodded and kept typing.

"Prentiss, you and Morgan go look at the crime scenes. They're in a 2 hours' drive. Reid you start on the geographical profile, JJ – the parents of the victims are coming here. Dave, you and I will be helping Reid with the profile." Hotchner ordered.

Everybody nodded and started their respective jobs.
