Undercover (AmaiRin Oneshot)

Undercover

"Okay kids! This is, is. Uh, Amai," Mesphisto's glaringly pink suit rustled as he slapped the back of the short boy behind him, Amai, earning a slight flinch. "I just know you'll all get along~ toodles," with that the clown was gone in a plume of glittery pink smoke, leaving the small black haired boy stranded in front of the class.

"Introduce yourself, Amai," Yukio instructed the nervous teen, giving him a reassuring smile. Amai gave a small nod in reply and straightened his back slightly,

"I-I'm Amai, please take care of me," he looked up at the class and immediately made eye contact with the blue eyes of the teen sitting across from him, his own dark orbs widening at the clarity of the blue he stared into, a spark of familiarity igniting in both boys.

"Any questions?" Yukio asked the room of teens as a pregnant silence filled the room. A hand shot up from the back and Yukio gestured for Bon to speak,

"Why do you want to be an exorcist, I mean. No offence, but you seem pretty weak."

"Bon!" Yukio exclaimed, jolting up from his seat.

"I-it's fine, he's r-right," Amai interrupted the oncoming scolding. Bon wasn't wrong after all. Amai stood at a measly five foot, with silky black hair that covered his doe-like eyes, gleaming a deep obsidian, contrasting against his pale skin. His frame was by no means one of a fighter, the baggy uniform he wore did nothing but exaggerate his small figure.

"Um, m-my older brother asked me to j-join. So I d-did," his answer came out weaker than before only just above a whisper now. A second hand made itself known, Shima.

"What's your last name?" He asked, the question seemingly and normal. Amai paused as if he had to think about it before answering with a question of his own.

"Uhh, which one?" The pink haired teen stared at him, an eyebrow raised. Rin choked down a laugh at the oblivious nature of the 'black haired boy'.

"What do you mean, which one?" Shima added to the questioning. Amai's hands gripped the helm of his shirt tighter, hunching over slightly trying to make himself smaller.

"I-I-"

"Why don't you just go take a seat, there's one beside Rin," Yukio broke Amai's nervous stuttering, said boy, letting out a small sigh of relief and all but running to his seat. The lesson passed quickly and Rin found himself paying more attention to his new desk neighbor than what Yukio was teaching. From the way his eyelids drooped as the day went on to the small pouts he would get when the lead of his pencil broke and then to the look of mild panic as he couldn't find his sharpener.

"Here," Rin whispered, extending his hand to the boy a few inches from him, sharpener resting in his palm. He watched closely as Amai's face contorted into surprise before he gently took the sharpener from the half demon's hand, bowing his head as thanks. Had he not been watching as closely as he was he would have missed the small, angelic smile the small teen gave him followed by the subtle smirk as they met eyes again.

"Thank you," Amai whispered back, handing the sharpener back. Rin reached out and took it, making sure their hands 'accidentally' touched. His sharp blue eyes caught the pale red hue that spread on the presumably younger teen's face as he faced his workbook. Rin felt especially giddy. He wasn't oblivious as to what was going on here and looked forward to teasing the 'younger boy' that Mephisto had deposited onto his not so literal doorstep.

"Class dismissed," Yukio's voice broke the spawn of Satan from his haze, the bell ringing loudly only seconds after his brother's words. Rin stayed put, waiting for the others to leave before collecting his stuff.

"Rin, I have a mission today. I'll be back tomorrow around lunch time," The half demon turned to his brother, grinning.

"Okay, don't miss me too much while you're away," he teased, earning an eye roll from the younger twin.

"Try to not be late for school," with that the two separated and Rin headed back to the old boy's dormitory. A mop of black hair caught his attention from just ahead, Amai. He sped up his pace, reaching the shorter boy in no time.

"Hey, Amai," he called as he reached the teen. Amai spun around in surprise, and quickly tried to step back, startled by how close they were but tripped on his own feet in the process. In a sudden burst of motion, Rin stepped forward, one of his arms snaking around Amai's waist, the other holding the teen just below his ass. Rin could feel the boy's warmth through his clothes as well as something coiled around Amai's thigh. A familiar feeling to him.

"Mmh!" Amai's short gasp was muffled by Rin's shirt as breathed in mouthfuls of the half demon's scent. "S-sorry!" He whispered, pulling away from Rin who shook his head in response.

"Don't apologise, it was my fault for starling you," Rin exclaimed, not liking how Amai immediately apologised. The teen let out a confused mumble of agreement and the two stayed like that for a moment.

"I-um, you c-can let go," Amai whispered, his hands applying a slight pressure to Rin's chest, trying to create a little distance between them. Rin however didn't hear him, too focused on the thing that stayed coiled around Amai's thigh. He traced it gently with his index finger, all the way to Amai's lower back before the boy in his arms let out a strangled gasp and he let a grin cover his face. A tail, a tail much like his own which was similarly coiled around his own thigh. A sudden weight slumped against him as he felt Amai shake slightly in his arms.

"A-ah, I'm sorry!" Rin apologised and made a move to let go of the black haired teen.

"N-no, don't let go!" A small voice called to him from its place huddled in his chest. Amai's hands gripped Rin's shirt as tight as he could as his knees gave out. Rin hurriedly held him tighter, his hand that was placed on his thigh now held Amai's butt, hoisting him up so Rin carried him. Rin felt the tailed boy squirm against him, a light panting filled the half demon's ears as an intoxicating scent infiltrated his senses. "Ngh," Amai let out a small groan as Rin's hand instinctively gave his ass a squeeze.

"I-I, uh," Rin fell over his own words, he could feel his 'junior' starting to wake as the small teen in his arms grinded against him, pressing their bodies against each other. The half demon's mouth watered as he stared longingly at Amai's pale, untouched neck. He couldn't help but hold the teen tighter, slipping his hands under the boy's school shirt to touch his skin directly.

"Mmh!" Quiet moans rang out as Amai pressed his nose against Rin's collarbone, basking in his scent as the demon traced the base of his tail. A sudden moment of clarity broke Rin from his intoxicated state long enough for him to realize they were still outside. He swallowed the spit that had gathered and found the nearest door, slamming Amai against it. His eyes grew hazy again as he fumbled for his teleport key, the younger demon now dragging his tongue across Rin's neck. He put the key in, the two bursting through the doorway of the old boy's dormitory, falling to the floor in a heap. Amai's back arched up, pressing his body against Rin as the half demon ran his tongue against his warm skin, his leg moving to shut the door.

"I-I'm sorry," Rin whispered, grinding his bulge against Amai's, "but I can't stop." The bluish black haired teen's hand slipped down Amai's pants and rubbed the base of his tail, applying slight pressure as the younger quivered under him.

"God Damnit, Rin," Amai's voice came after a shallow moan but more confident than before, his tone changing completely as he took steadier advances, "you make these undercover missions hard." Amai's body morphed slightly, turning into a much more familiar form. The Earth Demon's clawed fingers dug into Rin's shirt, pulling it off in one swift motion.

"Not as hard as your dick, big brother," Rin spoke dirty words into Amaimon's ear.
