Yukio's frown deepened as he noticed another glare from his brother. All night Rin has been giving him dirty looks behind his back and they had barely shared two words. His brother's lips had been stiffly pursed since he got home and only replied in short clipped tones.

Yukio turned back his covers and cast one more worried glance to his brother, who was curled up under the covers, before he turned off the lights and climbed into bed as well. He turned restlessly long after his brother started snoring, your words prodding at his mind and keeping him awake. He looked across the room to his drooling brother again and asked himself for the millionth time 'Why is he mad at me?'

Last he saw his brother he was bouncing with happiness as he left the class room with you.

…

You. His eyes narrowed. That was it, you did something.

Suddenly, there was a weight on his waist. His eyes flashed up to meet yours for a split second before he reached for his gun on the bedside table. You just barely caught his hand before he grabbed it, and with demonic strength you pinned his hands on either side of his head.

He grunted and fought back, squirming beneath you, trying to kick and thrash his way to freedom. After much struggling to no avail he fell still, both of you lightly panting from the struggle.

You smirk down at him, pulling his wrists farther up and holding them with one hand while the other slipped under your skirt. Yukio's eyes blew wide when your had reappeared holding a pair of handcuffs, his fight came back full force.

You scowled as he started to squirm under you again and press your lips hard to his, effectively stilling his struggles. You pulled away with the click of the handcuffs. Yukio looked up and cursed to see his hands cuffed to the headboard.

"Now was that so hard? ~" you nearly purred, torso pressed against his.

He glared down at your playful smirk. "What do you want?"

You straightened up and gave him a shrug. "I'm a Succubus; I come to men in their sleep to corrupt them." You leaned back down and twined your fingers in his hair with a dark look. "And you, Yukio, are just too deliciously pure for me to pass up."

He ground his teeth and made you reel back when he opened it again. "That's why I say to you, run from sexual si-"

Pain blossomed across your body, like being stabbed by millions of needles as he spoke from one of your fatal verses. You quickly slapped a hand over his mouth, body trembling slightly as you tried to regain your composure with ragged breaths.

"Yukio," You growled at him. "I have a gag, now if you don't want me to use it, I suggest you don't pull that shit again."

He looked at you with a sense of smugness that made your glare darken. His look lessened when a wicked smirk curled onto your lips. "If that's the game you want to play, then so be it." You placed a manicured finger to his forehead and gave him your most demonic smirk as your voice came out enchantingly melodic. "Achat, Shtayim, Shalosh."

There was a small flash of purple light and suddenly Yukio's body felt like it was on fire. It felt as though flames were licking at his skin, but not flames of pain, no, flames of lust. Suddenly all his senses were hyper aware, he could feel every caress of the blankets, the delicious pressure of your hips resting against his, the way your torso melded to his.

Without even knowing it, he let out a groan, need for you taking over his mind completely. He strained against the cuffs in attempt to touch you. You chuckle at his sudden change, his face was flushed and beaded with sweat and his breathing came out in desperate pants as he shifted under you to cause more friction.

You felt a firm lump press against your lower stomach and chuckled again, meeting his angry eyes. "Someone changed their mind fast."

"W-what did you do?" he gasped when your tong laved against his skin before nipping at his ear lobe.

"I didn't do anything, Yukio." You whispered hotly in his ear. "I just released all your suppressed lust, every dirty thought and every erotic urge."

You ground your hips into his and he released a low groan, moving his hips in response without thinking about it.

"Shh," You hissed against his lips as they tried to mold to yours. "You don't want to wake Rin."

His stomach sunk. Rin, he well knew that Rin was head over heels for you, if he saw him with the girl he loved…

The guilt in his heart vanished when you pressed your lips to his. He eagerly kissed back, despite his mind telling him he shouldn't. He opened his mouth with a light moan as you slipped your tongue into his mouth, playing erotically with his own. His body burned hotter with pleasure, he needed you like he has never needed anything before. He bucked his hips into yours and you pulled lightly at his hair before pulling away to 'tsk' at him.

You brought your lips to his throat, hands undoing the buttons on his night shirt. His breathing was ragged, the occasional moan slipping out as you nipped and sucked at his jugular, pulling his shirt away from his chest. His hips bucked again when you raked your nails up his chest before lightly rubbing on the way back down. You smirked up devilishly at him as your lips began to kiss farther down.

You nipped at his collar bone before giving it a soothing lick. His breath hitched in his throat, this was pure torture. A jolt went straight to his groin when you sucked at the red mark, setting up for a future hickey. His hands balled into fists as you alternated between searing kisses and jolting nips, your hands rubbing at his sides.

Your lips burned deliciously against his pecs as you licked your way towards a nipple.

"Nnnn…" He stifled a moan when you nipped at the rosy bud, giving it a laving lick. His back arched for you as pleasure hummed from your delicious torture.

He panted as your mouth trailed down past his belly button to nip at his abs, pressure building in his groin. You chuckled, "Look at this, an exorcist giving into a devil."

You sucked at the skin at the waist band of his pants before straightening up to look him in the eye. A devious hand moved down to slip into his briefs, lightly gripping his pulsing erection. He let out a drawn out stifled groan, hips bucking desperately.

You pumped him once and he writhed with smoldering bliss. "I though I was a monster." You teased giving him another pump, his glare melted into a look of bliss at the movement of your hand. "What happened to all that bitterness, Yukio~"

His body jolted with every slow, torturous pump of your hands. He had his head thrown back in ecstasy, hips bucking into your touch of their own will as your mocking words rang in his ears.

"Isn't this wrong Yukio?"

He felt you pull his pants and underwear from his hips, even the brush of the fabric arousing his frenzied body more.

"Isn't it wrong for a holy servant to fuck a demon of hell?"

His back arched sharply when he felt your slick heat rub up his hot, aching member. You ground in to him, tingles of pleasure racing up your spine as his hard arousal rubbed at your core.

Your lips tilted in a condescending smirk as you leaned forward, rubbing your almost bare chest against his, tail whipping excitedly. You looked at him with lidded, smug eyes as he sent you a half hearted glare. "Tell me, are you a virgin, Yukio?"

He gritted his teeth and said nothing. You gripped his member again giving him a hard squeeze that sent his body jolting. "Tell me, Yukio."

"Y-yes." He panted out with flushed cheeks.

You chuckled and he bit his lip to stop the groan when you rubbed his tip against your wet core. "Not anymore."

And you went down on him, sheathing him inside of you. You moaned lightly at the sensation, humming contently as you felt his body go rigid beneath you.

Yukio's mind went bland and his eyes rolled back in his head from the ecstasy. The groan lodged in his throat, you were so tight, you hugged him like a hot leather glove, making his senses go wild. And then when you move, oh god, when you moved. He bit his lip again to keep from crying out and tasted blood. Pleasure raced up his spine and he could only shudder at the intense feeling as you rocked on top of him, your own light feminine moans mixing with his stifled groans.

You smirked down at him, his eyes tightly closed and a fine pink flush on his cheeks as all he could do was whimper and moan. You rose up until only the tip remained inside before dropping down. He jolted upwards with a deep groan and bucked his hips up to meet yours as you continued the movement, your inner walls grinding heatedly against his member, hugging it so tightly he swore he was going insane.

You picked up the pace, tail swishing and hands bracing against his chest as you became for frantic. You leaned down, still riding him to mesh your lips with his, tongues entangling erotically.

He thrust up into you with reckless abandon, breath ragged and body burning with need for release into your velvet heat. You sucked at his neck and whispered hotly to him. "Don't you like this? You could have this whenever you want if you just give yourself to me."

You dropped down and gyrated your hips, causing you two to share a mutual moan of pleasure and you felt him practically melt beneath you.

"Give up the order for me, Yukio." He moaned as you rode him faster, back arching. "Follow me to Gehena." He could hardly take it, he was so close, the pressure rising higher and higher, ready to burst. "Become my fallen angel."

Your speed reached that of inhuman, as you rocked on him wildly, the pressure in your own gut building as you drew impossibly close. Then finally Yukio's body hit its limit and he snapped, arching hard he bucked his hips one more time into you, spilling his seed deep inside you. You moaned at the sensation of his essence coating your insides and came undone as well, riding out your orgasm, continuing to buck onto him, prolonging both your and his orgasm.

You stilled on him as you both basked in the after glow.

He watched as you raised yourself off of him, white liquid, his white liquid drip heavily down your thigh. You moved up to rest on his waist and he could feel your still pulsing core on his abdomen as you leaned down.

"Think about it, Yukio."

And, with a quick peck on the lips, you counted to three in Hebrew once more and he felt his eyes grow heavy. The last thing he saw was your eyes flickering with demonic madness.
