500 Days of Spencer.

Day (1)

Changes.

Morgan was beginning to worry. He couldn't help the butterflies that went through his stomach when Reid was near him. He couldn't control the mind numbing pleasure he got from listening to the other man ramble on about...anything really. And he just couldn't stop the smile that formed on his mouth when the other man walked in the front door of the BAU.

And god forbid the adorable genius do anything overly...well, adorable. Like blushing, attempting a joke, running a hand through his hair or awkwardly tripping over nothing. Morgan felt as though he couldn't control himself. Instead of feebly chuckling like the rest of the team, he couldn't prevent the bright grin that formed on his face and the laugh that escaped his lips.

Reid was just so utterly...perfect. And Morgan wanted to be around him all the time. He frightened himself with the things he imagined; holding hands, kissing, sharing ice cream, cuddling up on the couch... the possibilities were endless. Even just an extra few minutes with Spencer was like heaven to him. He got to see him smile, and ramble on about things that nobody else cared about, and they didn't listen to him. Only Derek did.

And so now, as he sat at his desk twirling a pen around in his fingers, bored out of his skull, all he could do was sneak glances across the room and hope the genius didn't notice. He traced his messy brown hair with his eyes, imagining running his hands through it. He watched in delight as the younger man sped through case files at lightning speed. And he couldn't help but stare as he bit his lip while jotting down notes.

"Hello there my chocolate god. Something on your mind?" Garcia said from behind his chair, scaring the absolute shit out of him. He visibly jumped, and she giggled.

"Jesus Christ. Baby Girl, warn me next time would you?" He said and spun his chair to see her perched on his desk, an amused grin on her face and an unmistakable light in her eyes.

"Wanna tell me anything important?" She asked him, just like she had yesterday, and the day before. He almost answered. But then once again, he lied instead.

"There's nothing new. What about you silly girl, how much did you buy at the mall this weekend?" He asked, knowing she would want to talk about all her amazing finds. He actually enjoyed listening to her talk about it.

"Enough that I had to call Kevin just so he could carry it all around with me. But you, Mr. I'm-going-to-change-the-subject, need to stop lying to me." She said, and he felt his heart rate speed up as he realised she was so on to him.

"Lying? I would never lie to you." He said with a smile, and bopped her on the nose with his pointer finger. She chuckled under her breath, but still looked determined.

"I see the way you look at him." She said suddenly, and Morgan felt the blush rise to his cheeks, barely visible, but definitely there. His stomach felt as though it might explode.

"Look at who?" He stammered, and this time she bopped him on the nose.

"Don't play dumb with me Derek." She taunted playfully, and he still attempted to play innocent, holding on to the last bit of his pride. She sighed annoyingly. "You like Reid, don't you?"

"Uh..." He stuttered, and she squealed, drawing attention to them. Morgan immediately looked at Reid, but the man was still busy doing whatever it was he was working on. When he looked back at Garcia, she looked like a kid in a candy shop.

"I knew it! Now I know you two aren't together, I mean, you would tell me if you were. So you're gonna go after him right?" She asked, speaking extremely quickly.

"I... I don't know Penelope, I mean, I'm still coming to terms with the fact that... I'm...I'm..." He explained, but didn't want to say it out loud.

"Gay? And in love with the finest man out there?" Garcia said with a smirk, and he looked up at her in amusement, but also respect.

"He... he is, isn't he?" Morgan asked feebly, and Penelope looked as though she might pass out with happiness.

"Of course! Now go get him tiger! It doesn't have to be today, but if you two haven't hooked up in a month, I'll kick your ass." She said with a smirk, and hopped of his desk. He stood to hug her, overwhelmingly happy to have her as his guiding light.

"Well I'm scared now." He flirted with a smirk, and she laughed.

"You should be." She said with a wink, and turned to go back to her lair. But before she could take more than two steps he grabbed her arm lightly.

She spun around and looked at him expectantly. He tried to say something, but nothing came out.

"No, Derek. It doesn't change my view of you at all. In fact, I couldn't be happier for you. So don't worry, your sexuality doesn't define you." She said with a small smile, and he sighed in relief.

"What would I do without you, goddess?" He asked, still holding her arm. Her eyes lit up with a sparkle.

"Probably die."

And so the story of Morgan and Reid begins.

A new chapter soon! Review! xxx
