Chapter 10

Spencer had been surprised at how satisfying it was to be with Aaron and Jack. The little boy was amazingly fun. He also had the ability to get under Aaron's skin in a way that no unsub ever could.

"But daddy, I wanted pancakes for dinner."

"I made spaghetti and meat balls. That's what we're having."

"I don't like spaghetti! I hate it. I want pancakes."

"You know the rules Jack. You have to take a no thank you bite. If you still don't like it, you can have cheerios. I'm not making two dinners."

Spencer wanted to chuckle but thought better of it.

On Sunday night, Haley came and picked Jack up. At least she was civil to Spencer. Spencer had been surprised at how sad he was to see Jack go.

He didn't mind having some more alone time with his mate however.

"Jack really is amazing."

"I'm glad you think so too. He's the one thing that made me glad I married Haley. The rest was a huge mistake."

"That's in the past now. Don't beat yourself up," Spencer said as he leaned in to capture Aaron's lips with his own. Tongues joined as Spencer tasted his mate; his arms snaked around Aaron's neck. He started disrobing Aaron. They were still in the living room, and Spencer had a plan.

He pulled Aaron around to the back of the sofa, pleased that his mate followed his lead. He grabbed some lube he kept stashed and then before Aaron could say anything spun him around.

"Put your hands on the back of the sofa."

As Aaron complied, Spencer nudged his legs apart. He heard the breath catch in Aaron's throat. He slicked up his fingers, the scent that Spencer was coming to associate with Aaron's arousal wafted up from his mate with increasing strength.

He ran his finger down Aaron's crease, teasing the sensitive pucker.

"Unh."

Encouraged by the fluttering under his finger, he pushed in slowly, starting to stretch his lover. He watched Aaron's head fall forward as his back arched and he pressed back until Spencer finger entered him.

Soon his finger was moving easily in and out of the tight passage, so he added another, scissoring them to stretch his mate. One more finger, and Spencer watched as Aaron started thrusting back onto him. He removed his fingers and reveled in the whimper that escaped from Aaron.

"I got you," he said as he undid his pants letting them pool around his ankles before stepping out. He tossed his shirt aside. He coated his hard cock with lube and then lined up with Aaron's hole, thrusting in steadily.

"Oh God."

Spencer smiled; he loved the sounds Aaron uttered as they made love. He gave Aaron a moment to adjust to the stretch and then started a slow thrust and withdraw.

"More…"

Spencer picked up the pace, and thrust harder, his arm wrapped around Aaron's chest. He brushed his fingertips over one nipple than the other as he switched angles.

"Yes."

Mission accomplished; prostate located. Spencer, careful to maintain that angle, started pounding into Aaron as his hand slid down to grab Aaron's cock.

He started a tactical mission of twin assaults of thrusting and pulling. He could feel Aaron tensing around him as Aaron shot, his orgasm screaming out of him.

A few more quick jabs into Aaron's swirling passage and Spencer went over the edge, filling his mate.

Spencer leaned over Aaron's back, just holding him while he took deep breaths to calm his breathing to a normal cadence.

The weekend passed too quickly for Spencer's taste. For once, he was truly enjoying being outside of work. But Monday came, as it often does.

It was hard to concentrate at work. Spencer kept remembering little things Jack said that made him smile. At other times, he would think about the amazing sex; his lips would part in anticipation.

"What's going on pretty boy?" Morgan asked.

"What?"

"Reid, you were a million miles away. What's going on?"

"Just thinking."

"That looked like more than thinking. Did something happen this weekend?"

"Uh…no just a quiet weekend."

Morgan was unconvinced. Ever since the case, Reid had been distracted and acting strangely. It worried Morgan. He knew he shouldn't be so suspicious. Reid would tell me if something was wrong, right? But he knew that Reid was all too good at keeping secrets. Dilaudid, headaches, the list was long, and Morgan was worried.

Instead of going home at the end of the day, he waited in his car for Reid to leave. He was shocked when he left the building with Hotch, and they got in Hotch's car together. This just ratcheted his concern up a notch. Hotch hadn't exactly been forthcoming either. Morgan still wasn't satisfied with his explanations about their last case.

He waited for the car to pull out of the lot and then started his own, following at a discreet distance.

When Hotch pulled into his driveway, Morgan parked across the street and watched as his co-worker went into the house. Why would Reid be going to Hotch's house?

He saw the two agents enter the living room and was unprepared for what happened next. Hotch grabbed Reid in a passionate embrace. Morgan's hand was halfway to the handle on his door. He was prepared to go beat the shit out of Hotch. What the fuck was the man doing messing with an innocent like Reid?

But then he saw Reid push Hotch back onto the couch and climb on top of him straddling his lap. Hotch wasn't forcing this, Reid was initiating it. He shook himself, trying to wrap his brain around what he saw. Hotch and Reid were having an affair? Wasn't Hotch straight?

He watched for a bit longer and then realized that no matter what was going on, he wasn't going to stick around and watch his colleagues have sex. He started his car and drove away. He did the only thing he could think of: pulling out his phone and calling Garcia.
