The Metamorphosis of Shinobu Oshino

This story takes place during the second season of the Monogatari Series. It's my very first Fanfiction so please be gentle with me^^ It's gonna be very lemony so if you're offended by nudity etc. please don't read it :D I'd love to hear some reviews. [English isn't my native language so sorry for grammar fails :) ]

It wasn't the first time Shinobu saw Araragi Koyomi naked. Since she lived in his shadow to prevent her from dying, she was following him around everywhere. She was there when he was going to school, she was there when he visited Senjougahara, she was there when he talked to Hachikuji so she was also there when he was taking his baths. Normally she stayed in his shadow so the sun wouldn't harm her, but it was annoying and also kind of boring. Especially because he wouldn't buy her the donuts she wanted. It was exhausting. Everyday the same procedure. He got out of bed, got dressed, ate some breakfast, tried to avoid his sisters who were always trying to find out how far he got with Senjougahara and then went to school. On the way to school he often met Hachikuji, tried to grope her and complained about her saying his name wrong. When he arrived he tried to lead a conversation with class rep Hanekawa and then sitting there all day long waiting for it to be over. Shinobu wanted something to happen. Something that would blow away the boredom, but the days remained the same.

"Hey Master?" she carefully asked when they were sitting around in his room doing nothing again. "What is it Shinobu...?" he replied, looking a little bit tired. It was one of those hot days again, on which Shinobu would've been thrilled to just cover the sun with a towel so she wouldn't have to sneak around in the corners to avoid it. Araragi opened the window, so a slight breeze could come in, cooling them at least for a few degrees. "Could you do me a favor? I want some donuts...on the way home I saw that Mr. Donut has a special sale again today. 3 Donuts for the price of 2. I would really love to have some now. I guess it's been a couple of years since you last bought me donuts. You know me well enough. I normally wouldn't beg you for something but this heat and the boredom is killing me...I'm just asking for this one thing." Shinobu quietly said. Araragi could see a sweat drop running down her cheek. He followed its way down with his eyes, till it rested on her chin for a moment, dropping a few seconds later on her white skirt, leaving a small stain. Her big green eyes looked at him begging. "I bought you some last week. I told you I can't spend all my money for donuts, just that you are happy." She leaned her head on her hand and glanced at him through her fingers. He knew she was devastated. Shinobu looked like always but the bond that connected the both of them was so strong, that he knew exactly how she felt. He could see her emotions, like he could see her fluffy blonde hair and the pink ribbon on her skirt. He was used to it but the way she looked at him gave him goose bumps. Not that he was scared of her, he knew she wouldn't harm him. (Who would buy her donuts when he was dead?) But he pitied her a little. She never begged for anything and he couldn't bear her gaze on his face anymore. "Alright, alright...stop doing that you know I can't stand it when you do that. I'll buy you donuts... ." He saw a little smile flashing over her face and a small wave of happiness and the feeling of success flew through his body. It wasn't his own feelings. He knew he lost this mental battle...again. It was a trick Shinobu used, since she found out that Araragi was feeling extremely guilty when he denied her something and she was pretending to feel sad. The emotions he received felt so real that he couldn't see the difference and always gave in, so she wouldn't transpher her wrong feelings to him anymore. Actually he felt something behind those fake emotions...a weakness she tried to hide from him. It was exhaustion and the feeling of getting a flue. Araragi knew it was, because she didn't suck his blood for quite a while now. He was happy because it was always really painful for him, but he also knew that they couldn't procrastinate it much longer or else Shinobu would die. The vampire lady got up and put her extremely big sunhat on. She smirked at him and walked out of the door. He followed her a tad annoyed by her boldness but he also was happy that he could get out of the hot room and get a little movement.

Outside Shinobu walked in his shadow behind him. He still could feel her good mood and smiled. "Why didn't we take your bike, Master? It's much more comfortable than walking the whole way..." she complained. "I left it at the school. Some dude cut my tires. Don't you remember? You were with me when I saw it." The look on her face was pure surprise. She actually didn't remember, which was very unusual for her. Normally she remembered every moment connected to Koyomi. "Something wrong Shinobu?" Araragi asked with a confused look on his face. Shinobu tried to shake the weird sense off which was growing in her stomach and replied "Kukuku...Master of course everything is alright. The heat is just brutal that's all." Shinobu had a bad feeling. Since she was sucking only Araragis blood on a regular basis, she developed an odd fondness for him. It was a strange feeling for her, since she never experienced anything like this before. It was just terrible and she wanted it to disappear. In order to prevent it, she stopped sucking his blood a while back which lead to more often appearing memory gaps and faintness. Of course she didn't tell him. Why would she? She was the vampire queen, Shinobu Oshino Heart-under-blade, and he just a regular human. It was none of his business. Araragi wasn't suspecting anything of Shinobus feelings towards him and just kept walking in the direction of the Donut Shop as he suddenly recognized that Shinobu was falling behind him getting slower and slower. He slowed down as well and smiled at her. He knew how hard it must be for her to walk in a sun like that. To cheer her up, he took her hand and tried to provide her as much shadow as he could. She looked at him thankfully and they finished their way to Mr. Donut.

Araragi and Shinobu sat at a table in a corner which was as far away from the windows as possible, each on one site. The blonde vampire had a table of different flavored Donuts in front of her. She was devouring them one after another. A little bit of frosting still stuck to her upper lip. As she sat there waiting for the load of food to sink down she took a curl of her hair and played around with it. Araragi glanced at her silently, wondering what she was thinking about. She was a really pretty girl he realized. Although he liked girls with short hair, he thought by himself that this extremely blonde hair was kind of arousing. Having that in mind Shinobu placed her head on the table and dozed off. He caught himself studying her body from her tiny feet wandering up her petite legs. His gaze rested a while on her almost not visible breasts and ended at her pointy ears. She still lay with her head on the table not moving a millimeter. He poked her arm and felt how cold she was. Normally her arm was rather warm but even with the hot temperatures her skin felt like she was completely frosted. "Shinobu? Is everything okay?" Araragi asked concerned. She didn't answer. She heard his question but she was feeling so weak. She knew she needed to suck his blood but they were in the wrong place for such a thing and she also didn't want those feelings to come back. So she just grabbed his arm and glanced at him with moist eyes. His eyes widened and he stood up in an instant. He softly shook her but as she didn't react he also knew what he had to do. He lifted her in his arms and carried her outside. He ran almost the whole way back home where he sneaked in the bathroom trying not to alert his sisters. He locked the door and started undressing Shinobu. He placed her in the bathtub and filled it with warm water while rubbing her arms and her body softly with a flannel. He undressed himself and got in the bathtub as well. It wasn't a big deal as they were always taking a bath together. They were used to it and so they were once again together in the tub.

"Shinobu..." he said quietly as he pulled her closer so she could bite in the soft spot in his neck. "My Master..." she replied as she buried her sharp teeth in his neck starting to suck his blood out. He felt the pain and quivered but didn't say a word. He knew it would only take about a minute till she regained her 'health' so he endured it and closed his eyes.

As Shinobu was sucking his blood she felt that the odd feeling was coming back, but in her weak state she didn't mind it. Actually she enjoyed it and just couldn't let go of him. She sucked and sucked the warm, red juice out of his neck as she recognized what happened. She was sucking on that soft spot for several minutes without noticing it and so she was suddenly flooded by a too familiar sensation. Her body started to change. First slowly but gradually faster, she was growing, her hair got longer, her lineaments got harder and suddenly she was back in her old grown-up body in which she once made Araragi a vampire.

Araragi was concerned. Shinobu was usually done after a short time, but now she was still on his neck. He opened his eyes and saw sitting in front of him in the bathtub...a naked really attractive women with pointy ears, long blond hair and big, firm breasts with cute pink nipples on them. His eyes got big and he was completely speechless. This wasn't the Shinobu from a couple of minutes ago...this was the Shinobu who made him a vampire and fought against Yotsugi and Yozuru. Shinobu blushed and stared into his eyes. He recognized, that he got hard and tried to hide it by pushing his legs unobtrusively together. His face got really red and he felt a heat wave through his body.

Shinobu was a different person now. She was much stronger and mightier and, what she would have never expected, was extremely attracted to Araragi. She saw his broad shoulders and his flat abdomen and got really aroused by this look he presented her. The vampire was confused. "How can I be this excited by just some human?" she thought. But although they were in the water she felt how she got really wet. She wanted him. Right now. She couldn't explain those feelings but she knew that they were there. Shinobu looked down and saw Araragi crossing his legs. The bond which connected the two of them was so strong, that she could feel that he was really aroused by her naked body. It tangled her mind a bit but she understood him because of the strong connection. Araragi was still a little stunned by her amazing body so she took the opportunity and slowly let her hand wander up his leg to his, now almost fully erect penis.

Araragi sat there still a little confused, as he felt Shinobus hand wander up to his errection. He never had intercourse with Senjougahara and also never with any other girl, so he always had to take care of his 'problem' by himself. The last time he did it was before he turned into a vampire because he was too embarrassed to do it in the presence of Shinobu. So he was completely loaded and his cock was twitching with every centimeter Shinobus hand was moving upward. Finally she grabbed his member and slowly started stroking it up and down. He didn't resist at all. Her grip was hard but also very soft and gentle. He couldn't believe it. This hot girl was jerking him off while they were in the bathtub...

Shinobu had regained her full powers. She felt as good as never before and she felt even better while touching Araragi. This boy...this...human was turning her on so hard. She wanted him right now. The vampire lady leaned forward and stared into Koyomis eyes. Their lips touched.

It was the most gentle and soft kiss Araragi ever had experienced. Not even Senjougaharas kisses felt this good. It was like their lips melted and as he opened his mouth, her tongue entered it and searched for his. Their tongues merged to one and Araragi thought that he was about to come. Of course he was just extremely horny and through this surprise act by Shinobu the thrill was much bigger.

Shinobu wanted him. So bad. She wanted his dick and she would do anything to get it. She stopped kissing his mouth and focused on his neck again. A small stream of blood was flowing out of the wound on his neck, over his chest and down into the bathwater. Shinobu licked it clean and caressed his neck, kissing him on the wound and continuing on his chest. Her tongue wandered down his flat belly and finally reached his member.

Araragi was so excited. Shinobu actually licked his dick. She grabbed it again on the shaft and her tongue was playing with the head. She pulled down his foreskin and caressed his glans with her tongue making him moan louder than he wanted to. He was so loaded and still surprised by this sudden outbreak of Shinobus feelings. He moaned again as she gently bit his shaft and started sucking on his cock. Araragi completely sank into the rhythm of the up and down and slowly recognized the feeling that was building up when he was about to come.

Shinobus head was still underwater, sucking Araragis dick. She didn't care about the water since she couldn't drown. All she was thinking about, was that she soon would have his long rod inside of her.

Araragi was close to his limit. His right hand grabbed a load of Shinobus hair as his left hand stroke her shoulder. He felt a big pressure building up in his penis. The feeling grew stronger and stronger and as she was swallowing his cock as deep as she could, he felt that his dick was pumping his sperm upwards and suddenly it exploded in her mouth. She spilled some of the thick juice and it was floating to the surface. Shinobu swallowed the rest and so her head came out of the water. She smirked at Araragi, who had a still little confused, but horny, look on his face. He didn't really understand the situation. "What exactly was this for?" He asked. "Human...your blood is making my insides really hot. I can't hold back now. I need you...no...i WANT you inside of me!" Araragi was waiting a long time for this moment to happen. Not with Shinobu but to finally lose his virginity to someone. And Shinobu in her grown-up shape was just the hottest, sexiest person he had ever seen. He climed out of the bathtub and took her hand. She climbed out as well and followed him to the door. The boy opened it and glanced outside, looking for his sisters. Wet and naked as they were, they ran to his room. He closed and locked the door and studied her now fully visible body as she was standing completely naked in front of him. He walked up to her and their lips met again. His one hand now slowly wandered down to her vagina as his other hand groped her mounds and played with her sensitive nipple. She moaned in joy as two of his fingers entered her folds. Araragi never saw a vagina in real life, only on pictures so he tried to recall it. With the mental picture in mind his thumb caressed her clit as his index- and middlefinger entered her pussy deeply. He felt that she was extremely wet and that his member got erect again.

Shinobu recognized that Araragis dick grew to its full size, as he was fondling her breasts and her clit. She pulled him very close to herself and gave him a deep kiss while moaning quietly over the pleasure he gave her. She broke away from his grip and lay on his bed, spreading her legs revealing her pink, and now extremely wet, entrance. She took Araragis hand and pulled him very closely. She clearly could see that he was a little bit nervous. "Everything is alright" she said "I want it...now!"

He sank down to his knees and licked all the way over her thighs to her exposed pussy. He smelled the scent of her folds and got really aroused by that making his dick almost explode without her doing anything. He softly licked over the outsides of her pussy making her moan a little bit. Then his tongue circulated around her clit which was making her almost go completely wild. She moaned really loud as his tongue entered her folds and his hands still groped her firm mounds. He tasted her insides and Shinobu got completely crazy over it. She screamed in lust and grabbed his hair, trying not to lose her mind. "Please...my master...I want you in me...now...!" He stood up from his position, just about to thrust his member into her entrance as he paused. "Wait..Shinobu...we have no protection...what if I get you pregnant?" "Stupid human...I'm a vampire you forgot? I'm technically dead. I can't get pregnant. And now stop talking!" Araragi was calmed down by this statement and stroke her entrance with his erection. She buried her fingernails in his butt cheeks as she was once again almost going crazy about the sensation.Their bond was so strong that Araragi could feel Shinobus arousal and it was exactly the other way around, so both of them could feel the double sexual excitation.

He pressed his erection against her entrance, slowly entering her. She moaned really loud in lust so he pushed it all the way in. Shinobu screamed in surprise and tightened her legs making it really tight for Araragi. He felt her pulsing insides and his heart rate elevated as he thrusted faster and faster into her wet entrance. He never felt anything as good as this in his entire life. His hand still lay on her breasts so he started caressing her nipples again, when she was pulling him closer giving him a deep kiss. He felt like he almost melted while he pushed his dick further and further inside of her. He was just about to come as he stopped moving. He was scared that the pulsing of her pussy alone could make his dick explode so he didn't dare to move at all and instead sucked one of her pink nipples into his mouth. When he was sure that he was safe, he pulled his member out of her slimy entrance and lay next to her pulling her on top of him. They switched positions and now Shinobu sank down on his extremely hard penis, which once again entered her. Now she was the one determining the speed and she wanted it...hard. She moved her hips in circles and he tried to shove his dick completely inside of her, matching her rhythm. Her boobs bounced up and down as she was moving and she grabbed his shoulders that she didn't lose her balance. They were completely sunk in their movement as they both felt that they were close to coming again. Araragis dick got extremely hot and waves of pleasure flooded his body as did Shinobus. She had gone completely wild and was riding him really hard and fast. "Oh..my god...I'm about to come...!" He shouted. "Urgh..kuku...ku...me, too..." she moaned with her last remaining power as their bodies were completely filled with lust. Shinobus entrance tightened as she was twitching around on him and his dick started pumping again. He felt so hot and suddenly everything felt like fireworks. He completely exploded in lust and pleasure and his dick fired one shot after another inside of her wet twitching insides. Shinobu couldn't hold it all inside so the sperm flowed out of her covering his dick in hot juice.

Slowly they came back to their minds. Araragi realized that he was still inside of her and pulled out, which caused all the remaining sperm to flow out on the sheets. The sexy vampire lady and the hot boy calmed down and their breaths slowed down. "What did I do to deserve this?" he asked, still breathless. "Kukuku...you let me live in your shadow and you let me suck your blood...that's the least thing I can do" she said, as her body started to shrink to its previous size. "Also I'm very fond of you so...maybe we can repeat this." Shinobu now had returned to her original size. "Thanks to you I'm feeling finally complete again. It's been years since I felt something like this." "Sure...I really enjoyed it too. It was really...surprising but, oh my god, you are so damn attractive in your mighty form!" "Kukuku. It's your fault I look the way I do now. Just let me suck your blood a lot and I will be to your will and as hot as you never would have dreamed of." "Agreed." he answered, pulling her into a hug and giving her a kiss on the forehead.
