Chapter 1

Derek was going to hell he knew it. It didn't matter how many unsubs he helped to put away, or how many lives he saved. He, Derek Anthony Morgan was going to hell. And why was he going to hell you ask? Because Derek Morgan was nothing more than a liar and a cheat.

"Derek, did you hear anything I said?"

Derek shook his head free of his thoughts, "I'm sorry, what?"

Penelope sighed, "I said that we're having a baby. Can you believe our dreams are finally all coming true?"

Derek smiled, "Yeah. This is great Baby girl."

Penelope beamed and kissed him before turning over and falling asleep. Once Derek was sure she was knocked out, he left the house heading for Spencer's.

Derek used his key to open the door and found Spencer pacing in his bathrobe.

"Hey, what's wrong?"

Spencer gasped, slightly startled, "I thought you weren't coming."

Derek kissed him, "Sorry."

Spencer, moaned, "Derek…"

"Shh, just…let me make you feel good."

Derek laid Spencer on the bed, kissing every bit of exposed flesh as he undressed him.

"God, you're so beautiful."

Spencer blushed. Derek chuckled as he reached for the lube and condoms. He frowned when Spencer tugged at his shirt.

"Off," Spencer panted.

Derek pulled his t-shirt off and went back to prepping him. He spread his legs and pushed two fingers inside making Spencer gasp.

"In a hurry tonight?" he grunted.

"I don't wanna chance it that Penelope wakes up and I'm not there."

Spencer just nodded and Derek said no more. He knew Spencer didn't like talking about Penelope especially while making love. It was long before Derek had three fingers inside and Spencer humping his fingers and whimpering. Derek removed his fingers, donned the condom, and pushed inside, stopping halfway.

"Oh God, oh God, so full," Spencer spoke his voice thick.

You say that all the time babe," Derek chuckled.

"Shut up and fuck me."

"As you wish."

Derek pulled out til only the tip was inside and slammed back into him.

"Aah!" Spencer screamed.

Derek kept that up for several moments making Spencer's body arch. Spencer moaned, wrapping his legs around Derek's waist drawing him deeper inside.

Derek settled for a few minutes causing Spencer to squirm. He chuckled before ploughing into his boyfriend. Usually Derek would have a mouthful of dirty speech but tonight he wasn't into it.

Spencer moaned against the hard thrusts, "Derek, touch me. So close."

Derek gripped his boyfriend's cock and stroked it. In time with his hard thrusts. Spencer arched his back and erupted with a loud cry of Derek's name. Derek was right behind him as he screamed Spencer's name. As per the norm, after Derek caught his breath, he pulled out, hand headed for the shower.

"Can't you stay for a little bit?" Spencer asked, sitting up as Derek returned to the room.

Derek sighed, "You know I can't. If Penelope wakes up and I'm not there…"

"I get it, but I really need to talk to you."

Derek kissed him, "Tomorrow. I promise."

Spencer sighed as he watched Derek leave.

The next morning found Spencer clinging to the toilet in the men's room. It wasn't fair, he sobbed. He sighed as he rinsed out his mouth. He didn't care what happened, he was telling Derek. He had just sat back down when Derek and Penelope appeared.

"What's going on?" he asked, noting that Derek wouldn't look at him.

Penelope beamed as she held Derek's hand, "We have something that we wanted to share with the whole team."

"Sorry Garcia, it's gonna have to wait," JJ said. "We got ourselves a bad one."

"Brace yourselves," she warned as she clicked the remote bringing up the pictures as the team filed into the conference room.

"Oh my god," Garcia gasped, turning away from the images of four charred women.

"Brenda Mackenzie, thirty-two; Heaven Daniels, nineteen; Jamie King, thirty-two; Alisa McDaniel, forty. All of the married with children. Each of them left home and found the next in the park within days from each other."

Derek whistled, "This is overkill. To burn a body from head to foot?"

Emily nodded, "It takes a lot of time to do that."

Spencer frowned, "He's targeting women who are married and that have children, why?"

"It's clear he has an issue with these types of women," Derek commented.

"Wheels up in thirty," Aaron spoke as he closed his file.

"Alright Garcia, what was your news?" Emily asked.

Garcia reached for her husband's hand as she placed a hand on her stomach, "We're having a baby."

Lots of squeals and congrats and pats on the back were issued. Spencer just sat in shock.

On the jet Spencer sat in the back with his thoughts. He had always had thought that maybe he and Derek had a chance but now… he sighed.

"Spence?"

Spencer looked up at JJ, "Yeah?"

"You okay?"

Spencer nodded, "Fine."

JJ frowned but nodded.

Things were so busy once the team landed that Spencer didn't have time to pull Derek aside. It wasn't until after the profile giving that Spencer had a chance.

"Derek, please, I need to talk with you. Its important and can't wait."

Derek frowned, "What is it Pretty boy?"

"Is there somewhere more private?" Spencer asked looking around.

Derek thought for a minute before he spoke, "Follow me."

Derek found them an empty room and ushered him before shutting the door. He immediately backed Spencer against it and kissed him.

Spencer moaned, "Derek, please."

"What do you need baby?"

Spencer stiffened and pushed Derek away making Derek frown, "I didn't ask you to come in here to fuck. I needed to talk to you."

Derek took a step back, "What is it?"

Spencer swallowed, "Derek, I'm…I'm pregnant."

Out of all the things that Derek expected for Spencer to say, that was nowhere on his list.

"Wait, what?"

Before Spencer could respond, there was a knock on the door. Emily stood outside.

"Hotch is looking for you two."

Derek sighed, "We'll talk later Pretty boy."
