Rin's Blue eyes fluttered open as the sun poked through the curtains of his room. He reached around for his feline friend next to him but Kuro must have been out and about again, for he wasn't next to Rin. The half demon sighed, last night was nothing but lust and Rin felt guilty for leading his friend on, he wanted to explain himself. 'I wonder where he went off to?' Rin thought shielding his eyes from the bright morning light.

"He went out with Aniki today." A familiar voice rang out through the room and it made Rin's heart flutter. His blue eyes peered over to where the voice had come and sure enough there sat Amaimon on Rin's desk. "Good morning." He said cheerily when he jumped off the desk to plant a peck of a kiss on Rin's forehead.

"Nii-san!.." Rin blushed and looked away, he felt different in front of Amaimon, his body felt hot his tongue felt tied and he could feel the blush on his cheeks. 'Da' fuck is wrong with me?' He thought his eyes looking over his big brother who sat next to him smiling, lollipop in hand.

"Ne, Rin do you want one?" Amaimon pointed to the purple lollipop. "It's really good, do you like grape?" He smiled as sweetly as a child, and it made Rin's heart beat pick up and he could knew Amaimon was able hear it.

"Y...yea, I'll take one." Rin stuttered taking the matching purple sucker, looking anywhere but his brother's piercing green eyes. 'I'm still fucking naked man! I wanna put some clothes on already.' Rin thought blush tinting his cheeks as he covered himself with the duvet of his bed. He took the lollipop in his mouth, Amaimon watching intently.

"Don't worry about being naked." The earth King said. " I don't mind, plus I've seen all there is to see." Amaimon teased answering his little brother's thoughts which shocked the latter slightly. "What?...did you think only you could hear other demon's thoughts?" Amaimon teased when he noticed Rin's reaction.

"Oh...OH! Well I mind being naked all the time especially around you. You might rape me again." Rin pushed Amaimon off his bed and stood holding the blanket up around him. Amaimon just laughed at him his lollipop only a stick now.

"Please, I 'raped' you little brother. Ahahha come on it's not rape if you liked it." The Earth King teased throwing the stick of his sucker in the trash. Rin ignored him and pulled on a fresh pair of boxers and a fresh T-shirt.

"What did you want anyway Nii-san?" The bluenette asked his hand on his hip the other pointing the sucker at Amaimon with his tail twitching behind him. Amaimon looked him up and down and licked his lips. Rin looked so deliciously cute

"Ne ototo, can I have some more candy?" The green haired demon asked a devious smirk playing across his lips.

Rin raised an eyebrow, why was he asking permission? Rin looked away from Amaimon's relentless gaze. "Do whatever you want, it's not like I care." Rin crossed his arms trying to play it cool, but something felt different between him and Amaimon.

Rin was too lost in his thoughts with his guard down completely exposed much too lost in thought to notice the demon king's advances. "ITADAKIMASU!" Amaimon yelled as he pulled Rin's dark locks to tilt his head back and took a deep bite in the crook of the teen's neck.

Rin let out a gasp of air when Amaimon's fangs penetrated his pale skin, the blood flowed out of the wound down into his brother. Amaimon let out a slight moan as the sweet red covered his taste buds.

'He tastes so fucking good. Not just better than candy, he's better than anything.' The demon King thought.

"R…really? I taste good?" Rin asked holding onto his brother's green hair. Amaimon released the half demons neck and licked up as much as he could before the wound closed up completely. Amaimon gazed at his brother a smile on his face.

"You taste so good it almost makes me wanna suck you dry," The demon king chuckled at his double meaning, "but I'm no vampire." Rin just blushed and looked at his feet. For some reason he was happy he could make his Nii-san like that. Amaimon pulled Rin closer to him, his hands cupped the latter's face a mere inch from his own. "Do you want to taste it Rin?"

Rin immediately dove into the chance to kiss is Nii-san again, he darted his tongue into the wet cavern of his mouth where both appendages danced their sinful tango once again. Rin didn't bother putting up a fight for dominance this time he just went with the flow. 'Nii-san, it does taste good but I liked the taste of you better.' The half demon teen smiled into the kiss and bit on his brother's thin bottom lip letting blood mix with their saliva.

"Rin…let me have more candy too." Amaimon pleaded when they parted. Rin just smiled his eyes truly befitting of a demon, for once his sweet blue eyes held a tint an evil. That inherited red pupil of his father.

"If you want more you have to convince me how much you want it." A true demon was emerging in Rin as a devious plan was concocted. "Beg for me Amaimon." He whispered into Amaimon's pointed ear, his big blue eyes no longer looked sweet and cute to the elder demon; they had made a drastic change. The clear blue seemed more intimidating, sexy, and handsome

"P…please Rin please." Amaimon stuttered his cheeks tinted pink as he looked at his younger brother. He felt so small at that moment as though he stood right in front of his father. Rin smirked and shook a finger at his Nii-san.

"No no no Amaimon, don't beg with words. If you really want to curve your addiction to my blood, then show me how much you want it with your body." Rin pulled his brother closer by his ridiculous tie, he grazed over the latter's lips with is tongue slowly teasing him and finally crushing their lips together.

"Ahmm…" The elder demon moaned, he felt so powerless he couldn't do anything but let Rin's tongue explore him. Amaimon wrapped his hands around his little brother's neck and pulled them deeper into the kiss. Rin's flames flared around them again no need for kurikara to be opened as their passion over flowed.

Rin bit his own tongue to mix his blood into the kiss; it was Amaimon's reward for being such a good Nii-san. Amaimon's eyes widened once the taste of Rin's blood danced on his tongue.

It was exactly what he needed to snap him back from his powerless growled pinning Rin to the wall opposite them, he deepening the kiss. He was going to have to punish Rin for trespassing on the grounds of dominance wouldn't he.
