Spencer Reid One-Shots

Attempted secrecy

SUMMARY:
Derek Morgan warned his adoptive sister, Y/N, that she was only at the BAU to do a job, not fool around with any of his co-workers. Unfortunately, she tends not to do what she's told to when it comes to her brother.

——————————

Y/N
You currently sat directly on your boyfriend, Spencer Reid's, lap, enjoying the quiet groans escaping his mouth as you teased him by rolling your hips over his (clothed) growing bulge while your co-workers slept in rooms close by. The more you teased him, the more you remembered a conversation you and your adoptive brother - Derek Morgan - had 2 months ago.

You and your brother, Derek, worked for the FBI. He was part of the BAU, while you were part of Counter-Intelligence. According to a lot of people, you were basically Counter-Intelligence's version of JJ at the BAU.

Now, it was your first day. You walked with Derek, heading straight for the big glass doors separating the BAU bullpen from the foyer outside.

"Woah, woah. Pump your breaks, little lady. Where do you think you're going?" Derek stopped you from moving further.

"Uh, work? I don't want to be late on my first day." You chuckled.

"Get your butt back here." He gestured for you to com back to him, which if you didn't, meant he'd come to you.

"Now, you need to understand something, Y/N. You're here to work. You're covering as the BAU's communications liaison until JJ gets back from her maternity leave, okay?" Derek reminded you.

"I know." You nodded.

"You need to promise me that you'll avoid fooling around with any of the team. More for your sake than theirs." Derek warned.

"I'm not 16 anymore, Derek. You can't scare me into not sleeping with someone." You rolled your eyes.

"Promise me, Y/N. You'll focus on work." Derek insisted.

"Fine. I promise." You scoffed, turning on your boot heel to move away.

If Derek had caught you right at this moment, he would've been pissed, as not only did you fool around with one of his co-workers, but you started dating him as well. You and Spencer had known each other for 2 months, and had been dating for 1 month. It started 3 weeks after you joined the BAU. Garcia insisted on a night out, truth or dare was played and as a dare, you kissed Spencer in front of Derek. He didn't seem upset by it, knowing that it would be a one time thing, and you were drunk when it happened. Well, he was wrong. You were tipsy, not drunk, which meant that a lot of the previous night slowly came back to you. It was during those memory flashes that you remembered kissing Spencer and how good it felt. That kiss unknowingly sparked your romantic interest toward Spencer and - lucky for you - he felt the same way. That's how, on the first day of your 2nd month with the BAU, he secretly asked you out on a date. He wasn't aware of your promise made to Derek, he merely wanted to keep his developing relationship with you a secret for himself.

"You're so fucking beautiful and you're all mine." Spencer moaned quietly as you placed kisses all over his neck, eventually finding his pulse point, which made him twitch underneath you.

"Fucking tease." He chuckled.

"You know, I'm technically breaking a promise I made to Derek. I promised him 2 months ago that I'd focus on working, and I wouldn't fool around with any of our co-workers." You pulled away from Spencer, rubbing your thumb gently over his bottom lip without tearing your eyes from his.

"Well, what Derek doesn't know won't hurt him." Spencer laughed as he attempted to flip you over, but a knock on the hotel room door sent both of you into immediate panic.

"Who is it?" Spencer called out, while you quickly got off him and smirked at his bulge.

"It's Derek. I need to tell you something." Derek explained before he started to open the door. You raced to the small closet near the bed and shut the door, slowing your breathing down.

For the next 30 minutes, Derek and Spencer sat on his bed, Derek explaining his concerns with the case, while Spencer tried to ignore his painful bulge, and you tried to keep as quiet as you possibly could. After a while, he left the hotel room, leaving you and Spencer alone again.

"And I thought you were the chatty one." You smirked at Spencer, who gestured to his bulge that hadn't disappeared.

"Care to help me with this?" He asked, a pained look on his face.

"Of course, baby." You nodded with a smile, removing your pants while Spencer started undoing his belt. Wanting some privacy, Spencer pulled you on top of him before grabbing the comforter, draping it over both of you, so only your top halves would be exposed.

"Kid, I forgot to ask you some- WHAT THE HELL!" The sound of Derek's voice scared both you and Spencer. He sat up slightly and you turned your head, seeing the anger radiating from Derek's face as he stood near the wall opposite the bed. How neither you nor Spencer heard the door open was unknown.
