Inside of a lavish castle, a seemingly depressed Sonic the Hedgehog sits slumped over on a bench. His mother, Queen Aleena, saunters over to him. “What has you so glum my dear? It's a beautiful day, you should be out enjoying the world, hopefully finding me a daughter in law.” she says with a wink. Sonic glances over to her, but quickly returns to staring out into space. “That’s exactly the problem though mom.” Aleena looks at him questioningly “I’m not sure I understand, what do you mean?” Sonic begins to blush “Well...I mean...I can't...you know. (He sighs) I can't get a girlfriend…” he says quietly. Aleena chuckles “Oh dear me, I’m sorry son, but I’m having a little trouble believing you. You're such a handsome young man, what girl in her right mind would pass on you?” Sonic snaps back “It’s not funny mom! I just want a pretty girl, but none of them like me!” In Aleena’s peripheral vision, she notices Sonic's sister Sonia, walking into the kitchen. She suddenly gets a wicked idea. Smiling to herself, she turns back to her son to respond. “Oh sweetheart, that's simply not true, I know for a fact there is a very pretty girl that likes you.” Sonic perks up and excitedly says “What? Really?! Who is it?!” 


  Aleena scoots over and gestures over to the kitchen. Sonic looks confused, but stares into the kitchen nonetheless. When he sees no one else but Sonia, he turns back to his mother, with an annoyed expression. “Mom, my sister does not count. You know that's not what I’m talking about.” Aleena smiles at him, with devious intent just behind her eyes. “But isn't it though? Think for a moment, Sonia is very close to you, she has a lovely personality, she is absolutely gorgeous, and she definitely likes you.” Sonic blushes slightly “Yeah, but she's just my sister, it's different.” In a seductive tone, she replies “It doesn't have to be though.” Sonic is a bit startled by this “...Okay, I’m not following you.” She places a hand on his shoulder “ It's very simple, just think of your sister like any other girl.” Sonic looks at her wide eyed “...You...you can do that?” “Take a look at her my son. She is a very attractive girl, isn't she? (Sonic nods) Doesn’t it make you feel good, when you stare at her? (Again Sonic nods) Then it can't be wrong if that is what your feelings tell you.” Sonic stands up “Thanks mom, uhh... I've gotta go!” 


   Sonic races off upstairs. Aleena looks back over to Sonia “Now what to do about you?” she says with a smirk. Upstairs, Sonic has collected all of the pictures he could find of Sonia. After placing them in his room, he checks to make sure Sonia is still downstairs. Once he's confirmed this, he makes a beeline for her room. Inside, he grabs hold of the handle of her dresser, but freezes in place. His heart pounds rapidly inside of him, while staring intently at the chest of drawers. Finally mustering up the courage, he opens it. There he finds his prize, stacks of his sister's panties and bras. He quickly grabs one of each, and rushes out, back to his bedroom. After a few minutes, Sonic is in the middle of furiously masturbating, with the underwear he had stolen, while flipping through pictures of his sister. After reaching his limit, he cums all over her bra and panties. The next couple of weeks were difficult for Sonic. He desperately wanted to confess his feelings for his sister, but he could not find the strength to do so. Instead, he longed for her in secret, spying on her. Sonia was not careful with her privacy, in the castle she would often leave the bathroom door unlocked, sonic took full advantage of this. 


When she would take showers, he would crack the door open and jack off to the outline of her nude figure, behind the fogged over glass door. After she was done, he would “accidentally” walk in on her drying off. The first time she was already covered by towels, but the second time he caught a glimpse of her breasts, before she could cover them. When she slept, Sonic would sneak into her room and fondle her gently. Lightly touching her boobs, and rubbing his cock tip against her face. This kept Sonic's lust at bay, but it wasn't enough to satisfy him, that would soon change however. Sonic came home to what seemed to be an empty castle, it was intensely quiet, and Sonic didn't know anything about anyone leaving. He headed towards his room to lie down for a bit. Upon opening the door, Sonic was surprised to find his mother and sister sitting on his bed. “Mom, Sonia? What are you doing in here?” Aleena looked over to Sonia “Why don't you tell him dear.”  Sonia blushed and slowly rose to her feet. “Sonic...I, well mom...umm...she told me that you were...having some trouble...finding a girlfriend. She also said that...it would...make more sense for us to…” Sonia walked towards him “For us to what?” She got up close and put her hands on his shoulders. After a moment of avoiding eye contact, she quickly pulls her brother in for a kiss. 


   Sonic couldn't believe it, the sweet embrace of his sister was everything he had imagined and more. Sonia pulls away “You understand now, right? (Sonic nods) Fine, then go sit on the bed” Sonia says briskly. Sonic does as he is told, and sits next to his mother. Sonia’s blush deepens, as she looks to her mother “Mom, do you really have to be here?!” “Of course I do dear, I need to make sure you two are safe. Now get a move on young lady.” Sonia shuts her eyes tightly, and looks very flustered. After a moment of hesitation, she pulls off her shirt, exposing her bare chest. Sonic eyes are glued to her plump and perky boobs. “Please continue Sonia.” Aleena prods. Sonia fidgets with the sides of her shorts, finally pulling them down in a swift motion, revealing that she was not wearing any panties either. Sonic cannot contain himself, his erection bursts forth, surprising everyone. Sonia whispers to herself “Oh God. Oh God! This is so fucked up, that's my brother’s dick!” Aleena tears her eyes away from her son's enlarged member, and looks to Sonia once more “Well?” Sonia is startled, snapping back to reality, she realizes that this situation is all too real. Sonia slowly lowers herself, kneeling in front of Sonic. “...Would...would it be alright if I...s-sucked your…(Aleena glares at her daughter, Sonia takes note) cock?” Sonic is a bit too overzealous “YES! YES, PLEASE!” Sonia takes hold of her brother's penis, hiding her disgust, she shoves as much as she can inside her wet cavern.


   Sonic is blown away by the feeling, grabbing onto her head, he pushes in deeper. Sonia doesn't know what to do, Sonic takes control and brutally fucks her throat, muffling her screams. With a grunt, Sonic pops, releasing his spunk. “Oh God, oh God, oh God! Ugh it's so thick, and it's like there's no end to it. Why does it have to taste so awful?!” Sonia's mind was racing, her brother had ejaculated inside of her mouth, and she had no idea how to deal with that fact. He was about to pull out, when Aleen quickly put a hand under Sonia’s chin. Sonic removed his penis “Now sweetheart, you mustn't waste a wonderful offering such as that. Now I want you to show it to him.” Aleena released her grip, and Sonia opened her mouth, showing her brother the load he gave her. “Looking good sis...really good.” Sonic stares lustfully at her, Sonia shuts her eyes again. “Alright honey, I think he’s gotten a good look, now swallow it.” Sonia knew this was coming, but that didn’t make it any better, she closed her mouth and braced herself. She tilted her head back and gulped, to her shock and horror, there was still more. Forcing the rest of the viscous semen down her throat, in a second gulp, finally puts an end to the first of her many trials. She panted heavily from the exhaustion. “Sonic dear, please bring your sister over to the bed.” “Sure thing Mom.” Sonic grabbed Sonia(by the pussy? Ugh I feel awful for even writing that.)’s arm and pulled her towards the bed, she reluctantly lied down on it. “Sonia, remember what we discussed. It's time for you to be the loving sister I know you are, and help your brother in his time of need.” Aleena stared unflinchingly at her daughter, that look signified to Sonia that there truly was no escape from this.
