Lost Soul: Chapter 1

Giggling echoed through the dark room as the sound of cloth rustled against each other. Two bodies moved about on the bed, stirring the bedsheets here and there. A small moan escaped from the smaller framed body that laid under the other. Another giggle escaped the smaller boy as he tilted his head, allowing access to his neck. The older boy leaned down, sucking desperately at the younger boy's neck, leaving love marks behind. "Ahhh...stop teasing me already," murmured the younger boy. A chuckle came from the older boy as he kissed down the younger boy's neck towards his collar bone and even lower. His mouth lingered over the harden nipple of the younger boy's. Slowly, his tongue slipped out, licking the nipple leisurely. A smirk played across his face as the younger boy mewled from below him, arching his back. The older boy brought one of his hands, placing them on the other bud, tweaking it and swirling around it, tracing small circles. He engulfed himself in the pleasure of listening to the younger boy's small pants and gasps that mixed in with his seductive moans. He let his free hand glide down the smaller boy's body and in between his legs. He grabbed hold of the younger boy's erection, grinning as he heard the younger boy moan loudly. "Un...Riku...hurry. Please..." begged the younger boy.

"Not yet Sora...I want to take this slowly," replied Riku, "I want this to be etched into my memory."

"Ah! But...but you...you can see tha-! Riku! Mmm!"

Riku chuckled as Sora bit his lower when his finger slid over his entrance. He traced small circles around it, watching as Sora writhed in ecstasy. Small pants became moans and pleas as Riku continued his motion. Bringing his mouth over to Sora's entrance, he made Sora raise his hips, sticking his tongue right into the entrance, enjoying the view as Sora spread his leg wider with his arms as his only support to hold him up. Sweat beaded down Riku's forehead as he thrust his tongue in and out. He was reaching his limit. Taking his tongue out, Riku cursed, "Fuck." He could hear Sora whimper as he pulled away. "Don't worry. I'm only beginning," whispered Riku huskily. Riku reached for the lube that was placed on the small table next to his bed. Squeezing a good amount, he rubbed it over his own needy length before he went back to Sora, who laid with his legs still spread widely. Smirking, Riku returned back to Sora, placing his harden member at the entrance of Sora. "Heh, you know what?" asked Riku.

"Mm?" came the muffled reply of Sora.

"You're right. I should hurry because right now, you're so irresistible."

Riku pushed into Sora, groaning as everything tightened around his member. Letting out a low moan, Riku began thrusting. Moans filled the room as Riku thrust faster, pumping Sora's member with each time. Gritting his teethes together, Riku lifted Sora's hips higher, allowing him better access. "Nngh, Riku...oooooh, it's....so good!" moaned out Sora, "Ahh! Right there! Riku...again!" Smiling, Riku aimed for Sora's prostrate, pounding into him over and over. "I...can't-! Riku, I'm coming!" exclaimed Sora as he shuddered and came. Riku continued to thrust into him until he too came inside Sora. Exhausted, they both laid on the bed, trying to catch their breath. Sora scooted closer to Riku, cuddling into his arms. "Mmm, are you off tomorrow?" asked Sora. Riku stroked Sora's head and shook his head, even though Sora probably couldn't see it in the dark. "No, I have to perform a surgery tomorrow. Someone's getting a heart transplant," muttered Riku.

"Oh...you know, I'm glad that you're a surgeon," said Sora.

"Why's that?"

"Because...you're saving lives."

"Not true. There are many that die during the process."

"Mmm, but I mean for all the ones that do make it. Their life can be changed because of that surgery."

"Not all surgeries are successful. There can be negative outcomes after a surgery."

"Why do you have to be so pessimistic?"

"I'm not being pessimistic, I'm only telling the truth."

Without even seeing, Riku could already tell that Sora was pouting. Chuckling, he leaned forward and placed a small chaste kiss on Sora's forhead. "Well, I guess I do save some lives," he said. He heard the small laughter of Sora's voice, making him smile. Yawning, Riku closed his eyes, succumbing to sleep.

The snap of the glove caught the attention of the other attendances. "Are you ready Dr. Riku?" asked one of the nurses. Riku have a curt nod and grabbed a silver scalpel. The operation was beginning and Riku was already getting anxious. He placed the scalpel onto the living body, excitement washing over him. He began cutting, enjoying every moment the scalpel seeped into the flesh. When he was done with the cutting, the surgery began. It was a slow process, but Riku was taking in the pleasure of seeing all the red and the beating organs. He gulped slowly, letting out a shaky sigh. The cover placed over his mouth and the small tinkering sounds of the others blocked out his shaky sigh along with his small groan. After a few hours, the surgery was over. Riku took off the mask, the gloves, and his over coat that was used during the surgery. He washed his hands with soap in warm water quickly and drying them before heading out of the room. "Dr. Riku? The family wants to speak with you," said one of the other surgeons that was working with him.

"I'll talk to them later. I have to run an errand very quickly," replied Riku as he rushed out of the door and heading towards the pharmaceutical area.

He stopped in his tracks when a familiar figure came into view. Smirking, he hid in an empty room and waited until the figure passed by before he grabbed him, dragging him into the empty room too. Shutting the door with a quiet thud, Riku pushed the other against the door. "So-ra," called out Riku. Laughing lightly, Sora wrapped his arms around Riku, kissing him. "Done with the surgery already?" he asked. Riku nodded as he leaned in again for another fiery kiss. "I want you right now," mumbled Riku.

"Right now? But I'm still in the middle of-"

Sora was stopped short when Riku kissed him again. His hands fumbled as he tugged as Sora's pants. Turning him around, Riku made Sora bend over as he took off his own pants. "Riku...people will hear," whispered Sora hoarsely.

"Then don't be so loud," he whispered back.

Riku could already see that Sora was hard. Smirking, he whispered into Sora's ear, "Such a naughty boy." Sora smiled and ran his tongue over his lips seductively. "Looks who's talking," he replied back. Laughing in a low voice, Riku thrust into Sora, shuddering as Sora moaned. While he was thrusting, his hands wrapped around Sora's hard length and pumped along with the thrusts. Muffled gasps and moans escaped from Sora's lips as Riku thrust harder. "Ungh...Riku....can't hold...much longer," said Sora in between pants. Riku gave one final thrust before he and Sora came together.

Riku was fixing his pants when Sora's question caught him off guard. "Why is it that every time you're done with a surgery, you always come looking for me all hard and needy?" asked Sora innocently, "You're such a horny pervert." Riku glanced over to Sora who was smirking at him. He shrugged nonchalantly and strolled over to where he was standing, kissing him before opening the door. He held it open for Sora and watched as Sora walked passed him. He gave a small slap to Sora's butt, chuckling as Sora jumped at his action before glaring at him. Once Sora was out of sight, Riku stepped out and tugged at the white overcoat he was wearing. He was actually quite confused himself why he always got aroused after finishing a surgery. Riku had always tried to ignore that question, but it never seemed to go away. It was always there at the back of his mind. Walking back to his station, he stretched, mumbling to himself, "Now then, what shall I do tonight?" A small evil grin played across his face and then disappeared quickly.

-----------------------------

Night had fallen, but it was brightly lit by the pale moon. Riku walked the quiet streets of the city before making turn into the red district. As he walked, a young boy caught his eyes and the boy knew he did. Smiling, the young boy walked over to Riku. "Hey there, do you have some time?" he asked seductively. Riku stared at the boy for a bit before nodding. The younger boy smirked and took hold of Riku's hand, leading him into an empty alley. Riku watched in silence as the boy got on his knees and stripped off his pants. The boy took Riku's flat member into his mouth, coaxing it alive. Riku moaned softly, clutching onto the hair of the younger boy. Scowling, he pulled the younger boy away by the hair and slammed him against the wall. "How about we try something...more erotic?" asked Riku huskily. The boy winced, but nodded, making Riku grin evilly. He pulled the boy's pants away before thrusting into him. The boy let out a scream, but he stopped it shortly with his hands as he clamped his mouth with them. Riku thrust at a fast pace, observing the boy as he moved up and down with his thrusts. "Hey, what's your name?" asked Riku as he continued his invasion into the younger boy's body.

"Ha-nnn...ah! Hay-ah! Hayner!" he said in between moans, "What's...yours?"

Riku smiled and reached into his pockets, grabbing a scalpel. "You don't need to know," whispered Riku as he pulled the boy away from the wall, "Because today is your last day." Hayner looked at him confusedly. Grinning, Riku raised his hand that has the scalpel into the air and brought it down, stabbing the boy in the back. The boy's mouth opened for an agonized scream, but Riku clamped it his hand own hands. Laughing evilly, Riku stabbed into the boy as he continued to thrust into him. He stabbed the boy on the chest and slid the scalpel down the flesh. Excited by the blood, Riku let out a low moan. "You're so good," he muttered out. Stabbing continuously, he started laughing crazily. Flesh ripped apart, revealing intestines. Blood soaked into his clothes and splattered against his face as he thrust and stabbed. After a few minutes, Riku gave a light shudder, coming inside the now dead young boy. Looking down that the ripped body, Riku let out a small laugh. His hand reached into the mutilated body grabbed the heart. He tugged at it, pulling it out and stared at it. "Here's your heart...oh and look, there's the kidney and then the liver," muttered Riku as he pulled the other organs out. He stopped in his excavation and leaned down, kissing Hayner on the lips. "You were a very good patient...Hay-ner," whispered Riku. Standing up, he grabbed his scalpel and left the alley, no one ever seeing his bloody covered body as he made his way home.

When Riku made it back to his home, he walked straight into the bathroom and stripped himself of the blood soaked clothes. He stepped into the shower, turning on the hot water and letting it run down his body. Scarlet water flushed away as the water splashed against his skin, warming him. Riku closed his eyes and sighed.

"Mommy?" called out a child who was only nine, "Why is daddy not moving?"

"Daddy is sleeping. He's going to sleep forever," replied the mother.

"Why?"

"Because Daddy was a very bad man."

"A bad man?"

"Yes...a very, very, very bad man. Daddy was going to leave mommy and you. He was going to run away with another man, so mommy decided that daddy and that man should go to sleep forever."

"But...how come they aren't sleeping on the bed? They're sleeping on the floor...I think daddy is hurt. He's bleeding mommy."

"He's not hurting. He was going to hurt us. Daddy...daddy is just sleeping. Now then, be a good boy and go to your room."

"Mommy, you're bleeding too."

"Mommy isn't bleeding. This isn't mommy's blood."

"Then whose is it?"

"That's a secret. Now go to your room like the good boy your are...Riku."

"Okay mommy!"

Riku's eyes fluttered open. He choked back a cry and fell onto his knees. The water pattered against his back as he gave out choked sobs.

"Mommy? Who is that man?"asked the boy.

"You don't need to know," replied the mother.

"Where's daddy?"

"Daddy is gone."

"Where did he go?"

"Away."

"With that man?"

"...Yes, with that man."

"Mommy? Why is that other man here?"

"Because mommy needs someone to support her and you."

"...But mommy, you make weird noises whenever he is here."

"I do? Well then, why don't you plug your ears with these?"

The mother handed ear plugs to the younger boy as she smiled. The boy took it from her and stared at it and then nodded, complying to her. The boy stuck them into his ears and went to his room to go to sleep. He didn't hear when the door opened and the man stood there in his door way. He didn't hear when the man walk over to his bed side or when the man whispered something into his ear, but he did feel the man caress his face and touch his hair. The boy woke up with the man lying on top of him and finding that he wasn't wearing any clothes anymore. The man grinned down at him started touching him. "Mommy! Mommy!" cried out the boy. He shut his eyes tightly as the man entered him, crying as the pain coursed through his small body. He didn't hear when his mother entered. He didn't hear when the knife came down and stabbed the man. He didn't hear the screams of the man or the wild laughter of his mother, but he did feel the cold touch of his mother and saw the crazed look in his mother's eyes. He saw the blood stained face of his mother and the dead body that laid on the floor. He stared at her with fear as she leaned over and unplugged his ear. He did hear though, the low tone of his mother's voice, "Don't worry Riku, mommy is here. Mommy won't let anyone touch you...because only mommy can touch you. Only mommy can do this...Don't worry Riku, mommy will make everything better." He let out a small cry as his own mother brought herself onto his erect length.

Riku leaned against the wall of the shower, water running down his face. His aqua eyes darkened into an emotionless look. Quietly he called out in quiet sobs, "No...no mommy. I don't want this. Please stop. I don't want to enter you...I don't want to..."
