Chapter 5

The group spent a full day at the Todoroki mansion as preparations were made for Rin, Wor and Kuro to depart. Licht's manager, Rosen Crantz, cleaned and bandaged the wound on Rin's thigh. The demon continued to struggle with his instincts and after the trying battle, it was becoming rapidly more difficult to contain himself around Wor. By the time the jet was ready to take them to the USA Rin was nearly bursting into flames every time he looked at the Servamp.

"Perhaps it would be best to sedate him? Just for the plane ride?" Crantz offered. Rin's instincts caused him to growl menacingly at the suggestion, but he grit his teeth and nodded, knowing it was the safest option.

Rin boarded the plane first, reluctantly following a nurse wearing a white lab coat. The nurse had him lay down on one of the plush leather couches and buckle himself in before she stuck a rather large needle into his neck and pressed the plunger. He was asleep in minutes and the nurse took a seat nearby as Wor boarded the plane.

The flight took roughly ten and a half hours and Rin had to be sedated a total of three times, due to his demon blood burning through the medicine so quickly. Wor stayed close, but found that he was quite bored without someone to talk to on the long flight. He managed to sleep for a few hours, but he spent the rest of the time lost in thought or chatting with the nurse.

World End knew that once the plane landed and they had made it to the house Licht was allowing them to use, he would have to make his final decision. Rin had reached the point where he either needed to go to Gehenna or risk killing 'everyone in a 50 mile radius' as he had said. Going to Gehenna was out, so Wor wasn't really left with many other options. He looked at his eve, sleeping peacefully thanks to the medicine, and smiled. With his mind made up, he waited for the plane to land.

When Rin woke, the first thing he noticed was a pounding headache. Upon opening his eyes he also realized that he was no longer on the plane. He was laying in a very large bed in an unfamiliar room. The gray comforter was pulled up to his chest, his arms resting lightly atop the blankets. He realized that the light that touched his skin was coming from a large window above the bed. Rin looked around at the rest of his surroundings.

There was a large dresser on the left side of the room. Immediately to the right of the dresser was a door that appeared to lead into a walk in closet. Straight out from the foot of the bed was a large television that was mounted to the wall. Looking to his right he saw two more doors. The one closest to him seemed to lead to a bathroom and he made his way toward it as he struggled out of bed.

The bathroom was quite a bit larger than he had been expecting. On the left side was a large vanity with two sinks and a mirror covering the entire wall above it. There was a spacious walk in shower to his right and dominating the corner of the room was a Jacuzzi tub large enough for at least three people. He walked to the toilet in the back left corner of the room to relieve himself. As he washed his hands he caught a glimpse of himself in the mirror and suddenly his instincts struck him like a bomb.

"World End," he growled seductively. His eyes flashed with the blue flames and he rubbed his hands on his jeans before stalking out of the bathroom in search of his mate. Moving to the second door he had noticed, he pulled it open and stepped into a long hallway. There were many doors lining the hallway and Rin clenched his fists, fighting to stay calm. Suddenly his sensitive ears picked up on the sound of a television coming from somewhere to his left.

Rin nearly ran down the hall, coming to a stop at the top of a staircase. The sound was definitely coming from downstairs and he took the steps two at a time. Finding himself on what appeared to be the main level, in the kitchen, he ran forward to throw open the only door he could see that didn't lead outside. He was in the dining room now and he growled again, growing agitated at not finding his mate.

Kuro's meowing startled Wor and he pulled his eyes away from the TV to look down at the Cat Sídhe. When the plane had landed and they had arrived at the mansion, the cat had chosen to follow Wor rather than remain in the bedroom where he had placed a sleeping Rin. Wor only wished he could understand Kuro. He furrowed his brows in confusion when the cat stopped meowing and made his way toward the balcony just off of the living room. As soon as Kuro left, Rin burst into the room.

"That's why he was meowing. Good morning sunshine!" Wor called out cheerfully. He turned his head away from the TV and his smile was replaced by a sexy smirk as his eyes met Rin's and he took in the demon's flashing eyes and trembling limbs.

Rin couldn't manage to spit out any words, but he needed to know that what was about to happen was wanted by the Servamp. Forcing himself not to tackle the man, he held eye contact and clenched his fists and jaw, breathing heavily through his nose. At Wor's smirk he nearly whined and the man seemed to finally take pity on him. Wor turned off the TV, setting the remote on the coffee table before pushing the table away from the couch. He then looked up at his eve and smirked again.

"Whatcha waiting for?"

Those few words were all it took. Rin finally let go of his careful control and launched himself at the man before him. Wor gasped as he found himself suddenly pinned to couch with Rin on top of him. The demon tore his shirt off, shredding the fabric, before crashing his lips against World End's. The Servamp quickly opened his mouth, welcoming Rin's tongue and returning the kiss with equal vigor.

There was only one thing that Wor fought to remember as he started to lose himself in the passion. During the flight, while Rin was unconscious, Wor had spoken to the nurse who was somewhat of a demon expert. She had explained that during a mating the demon's instincts would force him to try to dominate his mate. If Wor wanted to balance their relationship, especially considering Rin already held so much power as an eve, Wor would need to take over and dominate their first time.

Just as Rin shredded his own shirt, Wor grabbed his hips and flipped them, pinning Rin to the couch on his back. He pressed their lips together once again and thrust his hips against the younger man's. Rin moaned and reached up to wrap his arms around Wor's neck.

"Mmm, you gonna ride me?" Rin's eyes flashed again as he bit at Wor's neck.

"Ah..." Wor groaned at the sensation. "No, I'm gonna fuck you into this couch," he responded. Rin growled menacingly in response and attempted to flip them again, but to no avail. "You're mine," Wor growled before moving to suck on the flesh where Rin's neck met his shoulder. Wor's hands moved down to pull the demon's belt off before quickly using it to secure Rin's hands above his head.

Rin was lost completely in the sensations, sounds and taste of his mate. He knew that his instincts were causing him to growl and fight back, but everything Wor was saying only served to turn him on more. When Wor bound his hands he struggled fiercely, but the Servamp was quite a bit stronger than him and he was helpless as the man used his free hand to unbutton Rin's pants and yank them down along with his boxers. As his erection sprung free he gasped and bucked his hips, searching for any sort of friction.

"Fuck you're hot," Wor sighed as he began to run his hands over Rin's chest moving down toward his eve's cock. As he took the demon's length in one hand he moved his other down to probe at Rin's entrance. Rin snarled and continued to fight, struggling to regain dominance. Wor ignored this and spit onto his hand, slicking his fingers before sliding one inside of Rin.

"Ah," Rin hissed at the intrusion, his eyes clenching shut at the uncomfortable feeling.

"Shit you're tight. Is...is this your first time?" Rin gave a small laugh that quickly morphed into a growl.

"Shut up and fuck me!" Wor smirked at the response and added a second finger, working them to carefully stretch Rin. The demon continued to struggle, but he seemed to be accepting Wor's domination and the Servamp felt a surge of power and love at the realization. Crooking his fingers slightly, Wor struck Rin's prostate and the demon moaned, arching his back as he thrust himself down on Wor's hand. Once Wor had worked a third finger inside of him Rin growled again.

"Fuck me...now!" Rin cried.

Rin whimpered slightly when the fingers left him as Wor stood to rid himself of his pants and boxers. The Servamp then positioned himself between Rin's legs and spit onto his palm, slicking his rock hard length before lining himself up with the demon's entrance. Wor slowly pushed himself inside and felt Rin totally surrender to his control. Reaching up, he removed the belt from Rin's wrists before pulling out slightly to thrust back in, sheathing himself to the hilt.

"Yes! More," Rin begged before he reached up to pull Wor into another kiss, thrusting his tongue into Wor's mouth. This time Wor let Rin win the battle of dominance between their tongues as he continued to thrust into the extremely warm heat that gripped his length. Rin raked his nails over the Servamp's back drawing a groan from the older man.

World End had never had an issue with lasting long enough to satisfy his partners, but for some reason Rin was testing his will power. He reached down to grip Rin's length, stroking him quickly as his own thrusts became more forceful and erratic. Wor was reaching his limit, but was determined to last until Rin came. Sitting back on his heels, he lifted the demon's legs placing his ankles over his shoulders. This caused him to begin striking the younger man's prostate with every thrust and he quickened his hand's movements to match the thrusts.

Rin cried out Wor's name and threw his head back against the couch as his orgasm tore through him. With a few final thrusts he felt Wor follow as the Servamp released inside of him, crying out Rin's name and thrusting through his orgasm. Soon, he pulled out and collapsed on the couch beside Rin, wrapping an arm around his waist. When they could finally speak, Rin asked him a question.

"How did you know?"

"Hmm? Know what?" Wor asked as he opened his eyes and licked his lips.

"About the domination thing?" Rin blushed slightly and Wor smirked.

"The nurse on the airplane was kinda an expert. We talked."

"I see," Rin nodded as he stood from the couch. "Well, come on," he said as he began to walk back in the direction of the stairs, still completely naked.

"Where are we going?" Wor raised an eyebrow.

"Back to the bed. Don't think I'm anywhere near done with you," Rin's eyes flashed again as he glanced back at the Servamp. "I don't plan to let you walk again for roughly a week." Wor's heart nearly stopped as all blood fled south to his groin. He quickly jumped off the couch and followed Rin upstairs to the large bedroom, only pausing once in his walking as his eyes landed on Rin's tail, swishing agitatedly behind him.

Curiosity overcame him and Wor reached out to stroke the top of the tail as they neared the top of the steps. Rin froze and released a low, seductive growl. His eyes flashed once more as he glanced over his shoulder at Wor. The Servamp hadn't seemed to notice Rin's reaction as he continued to stroke the tail, marveling at how soft it was. His hand slowly worked it's way up to where the tail met Rin's flesh before he tugged gently on the appendage. Rin released a small moan.

"Kōzan. Bedroom. Now." Rin's voice made it clear that this was an order and Wor didn't hesitate, loving the sexy, dominating roll Rin was dropping into. This was one of Wor's kinks when it came to sex. Even though he knew that no one could ever over power him, strength wise at least, it was a major turn on to be ordered around in the bedroom. To let someone else take control and call all of the shots was hot as hell and he would make sure not to disappoint his eve...no, his mate.

"Get on your hands and knees in the center of the bed," Rin pointed as Wor entered the room. Wor licked his lips excitedly as he followed the younger man's orders. As soon as the door clicked shut behind them, Rin moved to kneel before Wor and the Servamp realized what he wanted.

"Would you like me to suck you...master?" His smirk was cut off as Rin pushed his already half-hard length against his lips. Wor eagerly opened his mouth, lapping at the slight remnants of cum from the earlier orgasm, before pulling the length into his mouth and sucking hard.

Rin panted and grasped Wor's hair, running his fingers through the white tresses as Wor continued to work his mouth and tongue over Rin's length. The demon's mind managed to register the fact that Wor's hair was quite soft before his thoughts were cut short as Wor deep throated him. His hips bucked involuntarily before he pulled on Wor's hair. The Servamp released him with a wet slurping sound and licked his lips as he smiled up at Rin.

"Turn around," Rin ordered and Wor quickly moved so that he was on his hands and knees with his ass facing Rin. The younger man copied Wor's earlier action and spit onto his hand to slick his finger before tracing it over Wor's entrance. The Servamp shuddered and groaned when the finger slipped inside of him. Rin's free hand moved between his legs to fondle his balls and he quickly added a second finger.

"This isn't my first time," Wor ground out between clenched teeth. "Please fuck me now, master!"

Rin chuckled before abruptly removing the fingers and spitting into his palm to slick his erection. He grabbed Wor's hips and lined himself up before immediately thrusting all the way in, burying himself in the tight heat and moaning loudly. Wor cried out and thrust his hips back, meeting Rin's every movement even as the demon began to move faster. Suddenly Rin slapped the Servamp's ass causing Wor to clench around him.

"Shit," Wor cursed as he felt his orgasm begin to draw near. Rin then gripped his hips, so tightly he was sure they would bruise, before beginning to pound into him mercilessly. As his prostate was struck repeatedly Wor cried out his orgasm, spilling onto the comforter beneath them just as he felt Rin bury himself deep inside as the demon cried out his own release.

When Wor's clenching walls had milked him dry, Rin slowly pulled out and they both collapsed on the bed, gasping for breath. As their breathing slowed Rin moved into Wor's arms, burying his face in the older man's neck as he wrapped himself around his mate. His eyelids felt heavy and he decided that they should take a nap.

"Don't you wanna get cleaned up before going back to sleep?" Wor smiled into Rin's hair as he spoke before pressing a kiss to his mate's head.

"Why?" Rin mumbled. "We're gonna get dirty again as soon as I wake up." If Rin hadn't sounded so sleepy with that statement it would have made Wor hard again in an instant. Instead he smirked and cuddled the demon closer, allowing him to get some rest.

"I love you, Rin," he murmured. Wor felt Rin's lips curl into a smile against his neck.

"I love you, too."
