"Mmmm Rin!"

Rin was biting harshly at her neck as Yukio watched; getting a little worried that Rin was beginning to lose control but was snapped out of it when Shiemi grabbed him by the tie yanking him down to her. He studied her face for a while. It was flushed like the pink rose and her eyes were squeezed shut in pain and pleasure.

Shiemi pov

Oh my goodness what is happening! How did I end up like this? She peaked an eye open to take a look at the sight before her. Rin was viciously attacking her neck and Yukio was just starring at her with what she presumed to be lust. She really feels like a virgin right now...well because she is. She'd never even kissed a boy before and to know that her first kiss was with two attractive boys at the same time was mind blowing.

She squeaked when Yukio reached out a hand and began to squeeze at her large soft breast. It was like nothing she'd ever felt before. She still couldn't get over the initial embarrassment of enjoying such sinful things. She wasn't very religious but this... fucking with satan's sons and loving every second of it was pretty bad in her book.

"Yukio..."

His eyes widened at her for once calling him his given name.

She couldn't help the sudden urge to inhale deeply in the crook of Rin's neck. The scent was addicting. She was hit with a foreign ache in between her legs.

"R-Rin!" She looked like she was going to cry. She felt herself become very warm in between her legs.

/. reg. pov

Yukio's brain played back what the clown demon had said to him before after seeing how Shiemi reacted to Rin's scent.

"How in the world would we win over such conservative people?"

"Rin's scent is very alluring at the moment so that wont be a problem. Did you notice any resistance from Shima or Amaimon?"

Rin kept kissing her as he slid a hand around behind her to loosen the knot on her kimono. Yukio was surprised when the innocent blonde began to grind against Rin as she clung to Yukio's tie. She had a pained expression and the sadistic side of Yukio found it hot. He went to remove his glasses so they wouldn't get damaged but a small hand stopped him.

"No. Don't. I like them."

Shiemi said in between pants. Shit I really did give her a glasses fetish.

"Uh Rin!"

Yukio looked down to see Rin's hand disappear in between the blonde's legs and start moving vigorously. He couldn't see Rin's face, that was buried in her neck as he laid on top of her but he knew that if he could he'd be smirking with fangs bared.

Yukio was starting to feel a little left out. If it wasn't for him they'd never be with her like this right now.

The exorcist made Rin halt his ministrations when he realized something was wrong. Too many clothes.

He began to undress Rin quickly. He started at the shirt and worked his way to the belt and the black jeans. Shiemi just watched, her large chest moving up and down as she panted from the sight of the twins undressing each other. She caught the boy's attention when she nervously slid her hand down between her legs into her thin pink underwear. The way her loose Kimono fell off her shoulders, and her large breast that were just barely covered, her blonde hair a bit messy gave her an unusually naughty look. Yukio just gaped and Rin let out a low growl as his eyes flickered a bit.

Rin removed her hand and replaced it with his own. Yukio just watched her face twist into a silent scream when Rin's hand slowly slid over the wet lips of her heat. He sucked on her ear while he played with her. When she let out a surprised squeak. He knew Rin had rubbed up against her clit. She looked so shocked and it was obvious that she had no idea what that was. She began frantically thrusting and grinding upward trying to get Rin's retreating hand back where it was.

Rin backed off to let Yukio have some fun with their new toy. Yukio lowered his head just at her underwear and started to breath hotly on her. Rin smirked knowing Yukio's technique for teasing. It always drove him wild.

"Y-Yukio... please."

Oh god. Here goes the sadist. Rin thought.

"Beg me some more."

Rin watched in amusement. It surprised him how Yukio was so commanding during sex.

The exorcist put his hand lightly over the hem of her underwear.

"P-Please! Yuki-chan!"

She blushed furiously at the whiny tone of her voice.

He finally pulled off her underwear and put his mouth to her sensitive parts. Rin's mouth watered at the sight. He reached around and grabbed his twin's erection while he pleasured the blonde girl. She made cute moans and sighs when Yukio stuck his tongue in her. She was so wet and warm. She was beginning to tighten signaling her release but he pulled away and gave her one of his sadistic smiles she'd never witnessed. She was panting like crazy and needed to feel release.

Yukio turned to Rin and thought they should give her a bit of a show since she seemed to have twincest fantasies as well.

They began to kiss sloppily as they pumped each other's erections. Rin felt himself getting close so stopped him. He was getting impatient.

He whispered something in his twin's ear and Shiemi stared at them with interest wondering what was said. Before she got to ask Rin laid down on his back with his legs spread wide. Yukio got in between Rin legs, wrapping them around his waist. Shiemi squeaked when Rin grabbed her small but curvy, mostly naked body. He sat her on his torso and smiled wickedly at her and she shivered. Yukio came close from behind her and started to blow softly in her ear.

"Yuki-chan!"

The teacher began to grope her large breast and played with the pert pink nipples. While Yukio distracted her Rin slid his fingers inside of her and began stretching her roughly.

While Yukio played with her he inched his way inside of Rin without stretching him because they'd already done this several times. The demon removed his fingers from her heat as she mewled softly looking completely drunk and high. Yukio knew Rin's scent was getting stronger the more aroused the demon got.

Finally Rin slowly began to slide her hips down on him. Her big green eyes were lusty and shining with want.

She gaspe once he was all the way in. Yukio licked the shell of her ear, beginning to rock into Rin, causing her to also rock against Rin. The tension and pressure Rin felt was amazing, being filled in the back and wrapped around in hot wet heat was causing his eyes to flicker. Red. Blue. Red. Blue.

No. Not again.

He fought against it as he softly grabbed Shiemi's hips and began to rock her a little faster. His eyes were squeezed shut and he was taking deep breathes to calm himself.

The other twin was lost in his own world as he rocked into Rin and groped Shiemi's breast as their speed increased. He moaned softly and grabbed a hand full of blonde hair. Shiemi whined and writhed in pleasure. But Rin did not.

Yukio went a little faster and turned Shiemi's head to kiss her too lost in the ecstasy he was feeling. Shiemi moaned loud as she began to grind faster on Rin. One of her hands went to that sensitive button from before. Yukio panted in immense pleasure. Finally he looked down with half lidded eyes to see how his twin was doing.

The exorcist snapped out of it as he examined his brother. Rin looked like he was in absolute agony and Yukio couldn't figure out why. Shiemi continued to kiss him but they were lost and placed on his chin as he down at his brother. Shiemi was oblivious too lost in bliss. Yukio's face twisted in concern. Rin's hold on Shiemi's hips were extremely tight and almost digging into her but the blonde didn't notice.

Before Yukio could question him Rin let out a borderline scary growl and began to thrust wildly into her and rock against Yukio like an animal. He looked feral, like he had absolutely no control. Yukio let out a cry of pain when Rin clawed at his chest leaving a red angry look. Rin's eye shot open and Yukio gasped. The irises were completely red and his flaming horns were present. Shiemi screamed in pleasured pain as she felt herself clenching around Rin signaling her release. Yukio could only stare until Rin viciously glared at him forcing him to continue fucking him. They all were rocking fast as their releases were approaching fast. Yukio's eyes shut tight as he felt Rin become tighter around him.

Shiemi let out a cry as she screamed to the ceiling.

"Rin! Yuki-chan!"

Yukio uncharacteristically screamed as he came inside Rin who just growled with gritted teeth when he shot his cum inside Shiemi.

Yukio panted then he felt a sudden weight on his chest when Shiemi collapsed on him. He felt a surge of horror wash over him when Shiemi had angry red lines on her hips that weren't exactly gases but would definitely be bruises tomorrow. He looked at Rin and was shocked when he saw that his eyes were completely normal but his face was one of terror and his eyes were watering. Yukio pulled Shiemi off of him and went down to comfort Rin. The demon wouldn't look him in the eyes. He just sat there shaking and then he took a look at Shiemi's wounds and he let out a soft sob that broke Yukio's heart.
