Impersonations. Ch 11 LAST

The next day in cram class Rin just sat staring at Yukio, not really listening just amiring his hotness. He smiled to himself. Yukio was his. All his and he didn't have to hide it anymore. Yukio would frown at him every now and then, knowing the dirty thoughts going in the demons head.

When Yukio walked by Rin's desk as he lectured, he tripped. Everyone stared stunned. He regained his composure and looked down to see what got in his way and saw Rin's sheathed sword. He looked down at Rin who was smiling childishly waiting for the scolding but it never came. Yukio invaded his personal space. The class had been sensing something between the two but they didn't know if it was negative or positive.

Yukio grabbed Rin's face in his palm and pushed him and his chair, flying backwards and hitting the floor. Everyone was still silent. Suddenly there was a snicker that turned in to full blown laughter from Rin. Yukio just stood there until he felt his lips curve upward a bit and started to laugh. He helped Rin up and stared into his eyes for a second before going back to teaching. Everyone was stunned as well as confused. No shouting? No reprimanding Rin's childish behavior? And where had Yukio's seriousness gone? They all wondered but decided it was actually sort of... cute in a twinny sort of way.

Rin stared at Yukio's back as he worked, except it wasn't a glare like before. It was a hungry look. The younger had been working for hours or at least that's what it felt like to Rin. He sighed. He was so damn bored! And here they were lovers in an abandoned dorm with a very very willing Rin in peace and quiet but noooo this kid wants to study.

Seriously.

Rin got up and went over to his twin's desk and watched him for a while. Yukio's back and his broad shoulders were driving Rin crazy. He reached around and lifted up Yukio's shirt, kissing his neck as he stroked his abs like so many times before. Rin was stunned when Yukio flinched away from him and continued to work.

"What's wrong four eyes?"

"What are you doing?"

"What do you think I'm doing~" Rin stroked his back softly and his hand went lower and lower to Yukio's ass before his hand was grabbed.

"One track mind much?"

Rin just pouted and for once purposefully tried to play up to the cute kitten look, wagging his tail side to side. Yukio was focused on the tail for a while. His eyes following it's movements back and forth until he snapped out of it.

"One track mind? What does that mean?"

Yukio mentally face-palmed. He really didn't want to have to explain this now.

"It means that you only want one thing... sex."

"Really?" Rin looked thoughtful for several minutes. Yukio stifled a giggle, knowing it takes Rin's brain longer than necessary to process things. Yukio was shocked when Rin was suddenly in his lap.

"Rin I was busy!"

"I don't care! Make time for me!"

"God you're needy."

Rin scowled and began to kiss him. Rin opened his mouth, wanting Yukio's tongue inside. They stopped for a moment to remove each other's shirts. Rin smirked when Yukio began to pant like the last time. Here he was denying him at first and he's always the one to get hotter first. But they say the serious shy ones are wild in bed and Rin truly agreed with that statement. Yukio wasn't shy at all. Rin pressed harder into his lap and removed his glasses.

"Mmm..."

"I thought you were busy?"

"Shut the fuck up uke." He replied coldly.

Rin was pissed and also turned on by his attitude. Yukio rarely used profanity but it sent shivers down Rin's spine because Yukio came off as such a goody goody sometimes. Rin shut his eyes tight and moaned when he felt lips on his nipple. Damn. Rin felt Yukio's wet muscle massage his nipple till it was hard and moved to the next one.

"Mmmm Yukio..."

Rin began to grind on Yukio in the seat and they felt each other's erections.

"Y-Yukio!"

"Nii san..."

Yukio pushed Rin up to remove his pants. He wanted to go all the way this time.

He stuck his fingers in Rin's mouth without warning him.

"Suck."

Rin just obeyed. Yukio couldn't help but think how cute Rin looked sucking sloppily on his fingers. Yukio shimmied out of his pants and underwear, shuddering t how hard he was. He wanted Rin so badly. He pulled his hand away feeling Rin's adorable fangs for a second.

Rin gasped when he felt something wet and warm on his entrance.

"Y-Yukio..."

"Do you wanna stop kitten?"

Rin shuddered when he called him that. It was apparently his new pet name. When they were alone Yukio did alternate between Nii san and 'Kitten.'

"No. Keep going four eyes before I change my mind."

Yukio sighed. Rin was stiil Rin.

Yukio stuck a finger in and Rin gasped in pain at first but as Yukio added another he could tell he was getting closer to that spot.

"Yu...ki...OHHH MY GOD!"

"There?" Yukio smirked.

"Yes THERE!"

Rin began to thrust fast down on the three fingers and it was hurting Yukio's hand to he grabbed his hip to stop him and pulled out his fingers. Rin whined at the feeling of being empty.

"Just get in already!"

"Alright relax."

Yukio got a tight grip on Rin's tail and the demon moaned loudly in desperation. Yukio finally positioned himself and started to slowly slide in. When he saw Rin wince he did one quick hard thrust and hit his prostate immediately.

"Yukio! Go! Faster!"

Yukio began to thrust pinning Rin up against the desk. The desk was shaking like crazy at the activity going on atop.

"Nii san!"

Yukio bit his lip when he felt Rin's tail slip out of his hand and stroked his balls. He went even harder and shut his eyes feeling an overwhelming pleasure.

"Oh Yukio! I'm..."

"I know me too."

They were panting heavily and sweating. Rin just stared up into his face and grabbed his head smashing their faces together in a quick kiss. This made Yukio open his eyes. They connected as they felt the rush of orgasm fall over them.

"Nii san!"

"Yukio!"

Rin came all over their stomachs and Yukio inside Rin. They smiled at each other as Yukio rested his head on Rin's forehead.

"I love you Nii san."

Rin just kissed him as a response and then his eyes shut.

"Nii san?"

He smiled when he head quiet snoring. He carried Rin back to his bed and covered the both of them.

I love you sooo much Rin.

Funny Alternate Ending (has nothing to do with real plot of story Just Mephisto fun) ;p

Yukio reached for his glasses on his nightstand. That's strange? My hand looks smaller. He started walking toward the bathroom as he stretched. As he made his way to the bathroom he realized that his pajama pants were hanging slightly looser and so was his t shirt. He stepped inside the bathroom and went straight to the sink as he bent down to rinse his face after he removed his glasses again. He felt something tickling his shoulders and waist. He dried his face and put his glasses back on before wiping the dirt off of them. He looked in the mirror.

He froze. He looked at his face. He had his moles and green-aqua eyes but his features were softer. He looked down. He had a petite frame, with large breast and hips. His hair was jet black and down to his waist. His were lips slightly plumper and pinker.

"Oh my god."

Just then he heard the door open. Rin walked in or at least he thought it was Rin. He had the same petite frame with large breast accept slightly shorter. He had the same black hair, down to his waist, except it had the blue hue, and it was in one of those emo hair cuts with the bump at the choppy top and thick bangs. His hair also had little electric blue streaks. No moles but slightly pinker and plumper lips like Yukio's.

But he was oblivious as he walked right passed Yukio rubbing his eyes and he noticed he had brows and longer lashes. Yukio's jaw dropped.

"Morning Yukio." He said as he went up to the mirror and opened his eyes. Yukio covered his ears waiting for the scream that came.

"AAAHHHH! I'M A GIRL!"

"Rin-"

"I HAVE... Tits." At this Rin calmed down. He slowly rose his hands and held them. Yukio rolled his eyes. Rin began to grope his breasts and became entertained with that as he left the room. Whoa Yukio's kinda hot as a girl and so am I. Rin thought as he grinned.

Yukio clenched his fists in fury.

"MEPHISTO!"
