Sonic and Amy were walking at the park one day morning. They had been dating for nearly three months and well, it's unlikely for the pair to actually become a couple. It was a fine breezy morning where the birds are chirping, trees are swaying and no mad scientist to ruin the day.

On these days however, those weren't the happy ones for someone else.

The only one who couldn't accept their relationship was no other than his few seconds old fraternal twin sister, Saphira. She was the first to know about the relationship because Sonic told her everything during one of their talks together. She was shocked but she quickly hid it and tried to smile so that she won't upset him. The truth though, she was the one who is upset.

Saphie developed a childish crush ever since they were still kids. Surely it's odd how someone of flesh and blood would like their own sibling but for her, this is her true feelings for him. He was the one who protected her, took care of her, taught her the good and bad and even spent his sorrow to get her back when Sally exiled her to stay away from him. On that day, Saphie realized that it was more than just a crush now. It's her falling in love to him and the desire to be with him as a single soul. How she waited for so long to admit it but now.... It's too late.

Right now, she was behind a huge acacia tree, watching them from a distance. The blue and pin hedgehogs laughed together and would occasionally kiss each other affectionately. This broke the twin sister's heart further as she restrained herself to jump in there and separate them. Oh how she wished she would, but no. It's not right. Incest is a sin, she heard from others before.

"It... It doesn't matter anyway... As long as he is...happy..." Saphie swallowed her sobs and quickly head home to not disturb them. "I'm...just his sister..." She stumbled to find anything sharp, a pair of scissors or a craving knife, then went into the bathroom and aimed the sharp blade to glide lightly against her arms, whimpering and hissing as it cut through her skin.

"Why... Why does this hurt so much...."

(Listen to the song Serine By Sele P featuring Kagamine Rin. If you don't understand it, it's something like 'walking in the rain of eternal sadness, knowing that the one you loved won't love you back, thus drowned you while you try to move on.')
~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Sonic began to notice the sudden changing of things since he passed three months of his relationship with Amy. Every morning, he started to see his twin wearing long sleeved clothing despite the warm weather. When he goes to fight bad guys, she stayed at home because of 'errands' (She went to writing or drawing as a part time job). When he sometimes buys her favorite food, she declined the offer by saying she's full or not hungry. The worst of all, he always notice her getting paler and paler, and even took daily medication for some reason.

"Did you try bringing her to her favorite places?" Tails asked him one day while working on his X-Tornado. "I tried but she still didn't want to come out! I don't know what's going on." Sonic held his head in despair. "This is... This is something that I do not know between you two. You guys were the closest to each other!" The kitsune noted that. "Yeah... We were that close." Sonic looked at the sky in deep thought.

He cared for her ever since the two were separated from their mother. He remembered the time she nearly pushed him into the lagoon for fun, having races with each other, goofing off, fighting bad guys and protecting each other's backs. He also recalled the time when he got killed by Mephiles, and the first thing he felt was her tiny form, hidden beneath his quills, holding onto him like nothing else matters for her as long as he stays with her. He loved those times until he started to think that his relationship kept him too busy to have some bonding time with her.

His phone suddenly rang and he answered the call. "Hello?" "Hey Sonic! It's Amy." His girlfriend spoke at the other end of the line. "Um... I'm currently having a really busy schedule here so um... I can't be at the date we've arranged earlier. I'm sorry!" "Nah it's okay Ames! We'll arrange that at another time. Go do your business there!" "Oh thank you! Bye then, Sonikku!" She then ended the call. "Well, I guess that leaves me free time to talk to my sis." Sonic sighed as he puts his phone away.

"I'll get going, Tails. It's getting dark now." Sonic said to him. "Oh okay. See you later then!" Tails waved to him as the blue hero sped off.

Once he got home, the first thing he did was calling his sister. "Yo sis! I'm back!" No answer. "Where is she...? Saph!" He continued to call her. Then suddenly, he saw a trail of light coming from the bathroom door. He peeked inside then nearly gasped at the sight. He saw Saphie lying on the floor, with a razor on one hand and a pool of blood under her recently slashed left wrist. "Sis!!" He stormed in and swiftly picked up his bleeding twin, before shuffling around to patch up her cuts. 'Please don't die.... Please no...' He shut his eyes tightly and tried to shake off the nightmare of the situation.

....................................................
"Ngh..." Saphie slowly opened her eyes and was quite surprise to be not in the bathroom on the cold tiled floor but in their bedroom in the arms of someone. And that someone was a crying Sonic. She listened to his sobbing as his tears fell down on her face.

"S-Sonic....?" Saphie hoarsely whispered to him. "S-Saph....! You're awake!" He exclaimed and wiped his eyes before yelling at her. "W-Why were you cutting yourself?! Are you crazy?!" He glared at her in anger and sorrow. "I-I...." She couldn't answer him. Not like this.

"I what?! Tell me why, sis! Why?!" "I-It's because I LOVE YOU, Sonic!" She couldn't bear all this anymore. "W-What...?" He was taken aback by her reply. "I... I was in love with you, okay?! And well, you never love me back! I was about to confess these...feelings of mine to you someday, but A-Amy got you first! S-So tried to move on by being your nice sister at that point, but it was hard! So I cut myself to forget this aching pain in my heart! To move on the fact that you two were in a relationship! There! I said it, Sonic! You happy?!" At this, her voice got tired and all she can do now is weep, her head throbbing a little from crying too much and from blood loss. Sonic, astonished by this, remained speechless by her confession. "Just ....just forget it, bro.... I'll... I'll just go away then if you don't need me...I mean...what's the point of staying here anyway...." Saphie whispered and sighed, looking at her bandaged arms and hands.

"Sis.. No, please don't...do this..." Now it was Sonic's turn to cry as he held onto her frail figure, letting himself cry in her shoulder like before. "I'm so sorry.... I put you this way... I was a fool, a greater fool of my own. I thought... I thought I found real love from Amy but now... I just can't stand the fact to... Lose you like this... I'm so very sorry..." Saphie was surprised but she gently hugged him back and wept softly, while trying to comfort the blue hero that he really is. "I... Need you so much.. It hurts, blueberry..." "I know... I'll make it up to you. I promise." They slowly let go of each other and his vital emerald eyes met with her vivid sapphire gaze. He then tenderly caressed her cheek, which she purred at the warm gesture, and leaned his face close to hers before his lips were pressed against her own in a gentle kiss.

It lasted for a few minutes before the two felt desperate and started to kiss each other passionately, wanting to fill the hunger and desire in between them, mostly her own desires. Sonic nibbled on her lower lip, which she granted access to her mouth, and then darted his tongue to her sweet wet cavern, exploring the insides. The two played and fought for dominance as the male twin striped off his sister's clothing, their gloves and shoes. Being the mischievous one of the two, Saphie lets go of the kiss to attack on Sonic's neck.

"Aah!" He gasped when she licked , bit and suck on his neck, easily finding his weak spot. He decided to return the favor by biting and sucking on her ears. "Mmh!" She moaned while sucking on his neck, making her tail wag excitedly.

"Sonic?" She the stopped to look at him. "Yes Saph?" He also stopped too. "I-I started to realize before that I like blood play so please...?" She held up one of her arms that had been partially exposed by the loose bandages. "Hmm..." He tilted his head then started to gently lick on one of the cuts. "Amhn..~" She blushed and bit her lip when he did. He gained a bit of confidence as he licked on the cuts sensually, sending shivers of pleasure down her spine. "Oh g-god..." She moaned softly when Sonic kissed her wounded arm then to her small chest, which he doesn't mind as he groped some areas. She gasped and moaned as he suck on those areas before kissing to her waist.

"W-Wait..." She held his arms to stop him. "I wanted to try something." Sonic tilted his head in confusion but that vanished as he felt her pulling his rod out. "S-Saph!" He moaned out as she stroked his cock curiously, and rubbing the slit with her thumb. It twitched in her warm hand as she moved it up and down. "You're a healthy one too...~" She purred while continuing her actions. "I wonder if Ames did this to ya before..." As she spoke, she bent down and licked it gently, making him bite his lip. A few more generous licks then she took it into her mouth.

"Aahgn~!" He groaned and held her head as she started to suck him off like an ice pop, bobbing her head while doing so. She let out a him of triumph, which send vibrations on his cock. "Oh f-fuck...! Saph.... If ya gonna...continue like this...!" Sonic panted as he spoke while begging for her to stop, but she had no intention to stop and sucked faster until she heard him yell. "C-Cumming~! Ngh~!" He ejaculated into her mouth, which surprise her but she took it all in before letting go.

"Jeez... Did ya swallow all of it?!" He blushed while looking at her. "You tasted good, bro. I'm really happy." She smiled and wagged her tail. He blushed further then chuckled as he laid her on the bed. "Alright you little slut, let's do more ~" He then moved his hand down to her wet pussy, whereas she gasped as he rubbed her folds.

"Mmph~! Ngah Sonikkun~!" Saphie blushed and moaned when one of his fingers slid and invaded her insides. "Y'know, I never had this with Ames, so considered yourself lucky that we will lose our first time~" Sonic smirked eagerly and continued to thrust more of his fingers in her. "Aah~ Ooh~! S-So- Umph~!" She moaned loudly and arched her back as he hit her g-spot. Knowing this, he started to thrust his fingers there.

"Aangh~! Sonic, I can't.. Take it...~!" Saphie moaned out loud while writhing in ectasy. He suddenly removed his fingers out of her, which she whined at the loss of the feeling but then her breath hitched as she felt something else going to enter her. "I-I'll be gentle I promise..." Sonic panted and he slowly slid the head of his cock first.

"Haangh~!" Saphie bit her lip and gripped the sheets as he entered her little by little. Once he was fully in her, she gave him the go signal to start moving. Sonic nodded and began to thrust in her.

"Aah~! Haah~!" She let out moans of pleasure at each thrust and hugged his back tightly, sinking her fingers in. He groaned and huffed while thrusting her, while moaning her name occasionally. "F-Faster~! A-ah harder~!" She begged in a very lustful manner, in which he obliged and did as he told her. She threw her head back and moaned louder before gaspig and held his shoulders. "Mmngh~! T-There again ~!" He smirked seductively and adjusted his thrusts to hit that spot over and over. "Like this, my Raspberry~?" "Ahn fuck yes~!"

This continued on until Sonic felt himself going to release. "S-Saph I'm.... Very close~!" "Haah~! Me too ~!" The two held onto each other tightly until they let out a scream of a moan and eventually came, his fluids going inside her while her own soaked his throbbing member. They let out shaky breaths and panted as Sonic laid next to Saphie, pulling her close to him. She blushed when she felt his cock still inside her. "I wanna... stay like this, if ya don't mind.." He kissed her ear gently. "I don't mind at all." She purred and snuggled close to him.

"Love ya Saph." He petted her head as he cuddled her. "Love ya too, Sonic." She smiled at him and curled up into a ball and fell asleep, now contented that they are a whole again.

--End--

Bonus:

A week later~

"Yo Sonic?" Saphie peeked at the room to see him. "Yeah?" Sonic got out, fresh from the shower, while drying his quills. "Remember last week when you said we'll lose our 'first times'?" She told him while tilting her head a little. "Err.... Y-Yeah why?" He blushed lightly when she let that subject get out from her head. "Well... I had morning sickness last Tuesday and went to see the doctor this morning." "Wait y-you did?" He blinked in shock. "Yeah... She told me that I am positively pregnant." She did an awkward hand gesture, but her smile seems innocent and happy. "W-What?!" Sonic then fell down on the bed.

Saphie giggled a bit. "That's why you need to use protection if you want to do it so desperately." She then sat down to work on her new manga series and a poetry book. "So... What will be the baby's name then...?" Sonic groaned quietly. "Ohoho it's not BABY. It's BABIES!" She clapped her hands with glee. "Say whaaaat?!" He exclaimed.

'I got a lot of explaining to do very soon....' Sonic sighed while thinking how to explain this to his friends, mother and two siblings.

----Good Ending----
