Animalia
Aaron Hotchner X BAU G.N. Reader
Warning: sexual tension...
Like a dog, you shook your whole body as soon as you entered the HQ. It was raining dogs and cats for days. Even with an umbrella, your body was wet from the heavy rain. As you entered the bullpen, you saw your friends gathered around Emily’s desk as always. Whenever they were not doing reports, they were always brewing something. You made a little crease between your brows.
“It’s heavy raining, and how come you guys are already here?” You put your bag down and rub your hair with a towel. Thank goodness you always have your travel bag with you.
“Because I got this!” Emily showed you an ominous purple liquid in a flask.
“A poison?” You raised your brows.
“Better than that,” JJ grinned. “It’s a potion that makes you sprout random animal ears and a tail if they have any.”
“It’s been viral on the net.” Emily's smile grew broader, and you had a bad feeling about that.
“We gonna prank one among Hotch, Rossi and Strauss,” Morgan said.
“You’re out of your minds, people. Hotch, Rossi? Sure I understand. But Strauss? Am not gonna take part in this.” You didn’t have a death wish. Strauss? Seriously, Strauss?
“Oh, no, you’re in this,” Garcia showed you a tablet screen with ladders. On top of the ladders, you saw your name and the others.
“Each one of us chooses a ladder. One of the ladders will say, ‘You won,’ which means you’re going to prank one of them.” Reid nodded.
“I didn’t say anything,” you said drily.
“You’re automatically on this, Ace newbie,” Garcia winked.
“C’mon, choose the ladder,” Morgan urged you as he pushed your chair.
“Everyone’s already chosen? How can I know this isn’t a trap?” You squinted your eyes suspiciously.
“Of course, we’re gonna choose at the same time.”
It was definitely a trap. You knew it. But there was no evidence that they cheated on you. You groaned as you held the flask. You knew they wanted you to prank on Strauss. You could read that wish in their eyes so badly. No way you were going to go through that.
Your inside was boiling like the coffee you just made for your boss. You chose to prank on Hotch because he seemed to be like you. Well, he liked all of his teams, but you felt he was a bit protective of you, and you appreciated that. The coffee reminded you of the colour of his eyes. Under your friends’ watch, you poured the purple liquid into the coffee. According to Emily, it was okay and wouldn’t harm Hotch one bit except that you will earn scolding from your lovely boss. As you finished the coffee, you made a face to your friends after seeing lights in the Hotch’s office. Your friends gave you thumbs up with giddy faces.
Hotch replied ‘enter’ as you knocked on the door lightly. He looked at me quietly, waiting for me to talk.
“I got your coffee.”
Hotch raised his brows but thanked you nonetheless. You put the cup down on his desk and looked at him expectantly. Without a word, he took a sip and put down the cup.
“It’s good. I’ll finish it later.” He noticed your face crumble a bit. He looked over the window, and your friends quickly pretended they were working. “It’s a prank?” You hesitantly nodded. “They want me to drink this, whatever it is.”
“Yesh…,” you mumbled and started to fidget with your hands.
Hotch hummed and stood up, the coffee cup in his hand. Then, he held his cup lightly to show your friends who blinked at Hotch. You stared at your leader, who started to drink the coffee and soon blinded the window.
“I will forgive you,” Hotch smiled. But you felt a chill at that smile. It made him a predator. You unconsciously took a step backward when Hotch locked the office. “I know what you put in my coffee, F/N.”
What the fuck? They told you its purpose was to transform human parts into animals. But this? He was acting a bit strangely.
“Sit, F/N,” he simply commanded, but you couldn’t disobey the authoritative voice he was giving.
You just sat there and watched him pacing his office. Several times, he brushed his hair and face.
“You know, F/N,” he started to talk after a while, his back to me, “that thing also brings out animal instinct which I can hardly control.”
You could only blink at Hotch. When he turned, you saw two pointy ears on his unruly hair. It really worked! As he smiled at you, you didn’t miss the sharp teeth that looked like a canine’s. He slowly walked up to you, and you saw a large grey fluffy tail on his back. As your attention was focused on the tail, he stood before you. He slowly bent over you and inhaled your scent, sending light electricity all over your body. His hands gently pressed on your arms and slowly moved upward to your shoulders.
“Am I scaring you, F/N?” He whispered, but there was a low growl echoing from his throat.
Your throat only bobbed, your voice lost the way. His fingers, with his nails gotten long like claws, twisted your shirt lightly.
“Hotch…” You gulped, feeling like sweating as your body shuddered in the mix of excitement and worry.
He growled, and he lightly nipped your ear. “Aaron,” his voice echoed in your ear.
“Aaron," you murmured. Your heart was racing faster than anytime before. His usual stoic face was plastered with a large grin. His usual brown orbs were specked with yellow stars, a storm of lust and desire mingled together. His breath tickled your skin as he trailed down your neck. Aaron gently kissed your neck as his hands slithered inside your pants. His ears twitched, and the tail wagged from excitement. Your hands were trying to unbutton his shirt, but he tightly grabbed your hands to stop you. Aaron Hotchner wanted to dominate you, and he wanted you to be submissive and obedient. You whined in disappointment, but his grin only got larger.
His lips lightly pressed yours to swallow your moans as his hands were roaming between your thighs. His hand stopped, and he pulled away from you. In chagrin, you looked at him, and you found that the yellow specks and lust were no longer in his eyes. His ears twitched again as he licked his lips.
“Sadly, we need to stop.” He paused and watched you pout. “If you want to, we can still continue our exploration at my home tonight?”
You vigorously nodded, excitement building inside you once again. He smiled as your eyes darted to his ears and tail. He kneeled in front of you and put his head on your knees like a big dog. With Aaron’s encouragement, you scratched his soft ears. He closed his eyes, his tail wagging happily.
He jumped and growled at the door bearing his teeth with a sudden knock. He really did look like a dog or a wolf. You quickly schooled your expression and adjusted your ruffled clothes. Aaron crossed his arms, clearly mad from being interrupted.
“Could you open the door,” he asked you gently despite how irritated he looked.
You only nodded and opened the door, finding Rossi standing there with raised brows.
“I see Hotch didn’t like the surprise.”
You only shrugged, not knowing how to respond.
“Indeed, I am.” Aaron huffed. “Did you take part in this, Dave?”
“I just got here.” The older man rolled his eyes, gesturing you two his very wet coat. “But I see the wolf suits you, Aaron.” Then he left, leaving the door open so the team could see Aaron’s ears. Your friends quickly adverted their eyes as Aaron glared at them, but you saw their laugh-holding faces. You thought about giving them the finger, but Aaron lightly pushed you and closed the door.
“We’ll surprise them later when they let their guards down. In the meantime,” he pulled you to your arms. “I’ll gladly enjoy your company if you let me.”
“At your home?”
“At my home.” He grinned, and you mirrored him.
Later, much later, you and Aaron ordered each other the same potion and had quite fun.
