“O-okay S-sonic, I’m ready for you to…(she tries to keep from vomiting, while saying these next words) f-fuck me...with that huge...delicious dick of yours. (She collects herself, before she continues reciting her lines.) H-hurry up and shove it inside of me.” Sonia finishes, Sonic is harder than he's ever been in his life. With no sense of well being for his “partner,” he scurries between her legs, and haphazardly inserts himself. Sonia clenches her whole body, as in true virgin fashion, Sonic humps his sister as fast as he can, with zero finesse. She could feel his slimy cock relentlessly attacking her inner walls, and as much as she wanted it to stop, she knew that there was only one way it was going to end, which scared her even more. “FUCK! You feel so amazing Sonia! I could do this all day!” Sonic said, while feverishly thrusting his hips, and groping his sister's breasts. Sonia did her best to fight back her tears, as well as distance herself mentally from what was happening...but it was of little use. “You can if you want to sweetie. Sonia is yours now after all...well, maybe not quite yet.” Aleena baited her son. “Huh, why not?!” “It’s quite simple sweetie, to make a girl truly yours...all you need do is cum inside of them.” Sonia could feel her heart sink, remembering how this nightmare began, and how it is now reaching its inevitable conclusion.


   The day prior, Aleena knocked on her daughter’s door, and upon hearing the signal to come in, she entered. “What’s up Mom?” Sonia said brightly. “I have something important I need to discuss with you.” A little taken aback at her abruptness, Sonia responds “Alright, what is it?” Aleena sighs “It’s about your brother Sonic, he's having a very rough time right now.” Sonia puts a hand to her mouth “Oh no, what's happening?! Is he alright?! What's wrong?!” “He’s fine dear, it's just a little sickness of the heart. He can't seem to find himself a suitable mate.” *Whew* “Don’t scare me like that Mom, I thought he was dying or something!” she laughs in relief. “So let me guess, you were wondering if I could introduce him to one of my girlfriends, right? I do have one in mind, that's assuming she's still single that is, but I’ll giver her a c-” Aleena cuts her short “That won't be necessary dear. I've already found him the perfect match.” Sonia looks surprised “Oh, well don't leave me in suspense, who is this lucky lady.” Aleena smiles warmly “Why, I thought it would be obvious by now, it's you.” Sonia pauses for a moment, confirming to herself that she had heard her mother correctly. “Hahaha Mom, quit being weird and get serious, who is she?” Aleena sits next to Sonia, on her bed, and takes both of her daughter’s hands between her own. “Believe me, I am quite serious. This is a very important responsibility, I want you to bed your brother, and see to it that his every desire be fulfilled, as well become his betrothed.” She says this all, with the same motherly smile she always bestows upon her children. 


   Sonia is in utter shock, she's horrified by the words coming out of her mother's mouth, and praying that this was all some kind of sick joke...but as the conversation went on, it became very clear that this was no laughing matter. “YOU’RE OUT OF YOUR MIND IF YOU THINK I'D EVER DO SOMETHING SO DISGUSTING! GET OUT OF MY ROOM, NOW!” Aleena chuckles to herself “Sweetheart, you don't seem to understand, I'm not asking you to do this, I'm telling you.” “Absolutely not! Sonic would say the same thing, this is insane!” Aleena smirks “Are you so sure about that? Have you noticed that any of your undergarments have gone missing? It's because he’s been taking them...to masturbate with.” “You’re lying!” Sonia shouts, but she admits to herself that it would explain the missing bras and panties. “Am I? Let me tell you, he also spies on you while you bath. He's “accidentally” walked in on you far more than usual, am I correct?” “N-no…” “What he does at night is by far my favorite. While you sleep, he caresses your supple breasts, as well as gently rubs the head of his penis against your lips.” “SHUT UP! I’M NOT GOING TO LISTEN TO THIS ANYMORE, AND I WON'T BE A PART OF YOUR SICK PERVERSIONS!”  Aleena glares at Sonia with an icy focus. “While you are free to decline, I would advise against doing so. You see, if you refuse, you will be thrown into the streets, with naught even the clothes on your back. I will disown you, you will be stripped of your title as princess, and you will be exiled from my kingdom.” Faced with the threat of her life being destroyed, Sonia solemnly admitted defeat and accepted her mother's terms. Aleena went on to lay out specific instructions on how to treat, and what to say to her brother, the following day. They went over everything a multitude of times, pushing into the early hours of the morning. 


   “You, mean all I gotta do is dump a load inside her, and then I can do this for as long as I want?!” Aleena nods in response. “Well then get ready sis, cause I'm getting close!” Sonia was pushed to her breaking point. She may have agreed to this, under duress, but with the heinous act looming mere moments away, she could not bring herself to stand (or perhaps lay in this instance) idly by. “Sonic wait!” Sonia pushes a hand against his chest, and the other against the bed. “What? Why?” “Because I don't want this! I never did! Mom went nuts and forced me to do this! Please, you're my brother, just stop this insanity now!” Just then, Aleena grabbed Sonia by her wrists, and pinned her to the bed, she stares Sonic in the face. “Mom...is that true?” Doing her best to talk over Sonia’s screaming, she replies “I'll explain everything in just a moment dear, but first I need you to hold her arms down like mommy's doing!” Sonic obeys, and Aleena swiftly takes the opportunity to cover her daughter’s mouth. “There, that's better. Sonic, I need you to listen to everything I have to say…...Yes, it's true, I did force your sister to do this with you-but, I only did that because I knew she would enjoy herself at the other end. (Sonia struggles violently at hearing this.) That is, only if you do what I tell you, and make her yours by finishing inside. I promise, after that, this will all be water under the bridge, and she will gladly ride your cock as much as you want, all of her own free will. Just let it go inside.” 


   Sonic is hesitant, he wants to badly, but looking at the panic and tears in his sister's eyes has him conflicted. Aleena can see his indecisiveness clearly, and decides to try to tip the scales in her favor. She leans close and whispers into his ear “Come now, you’ve wanted this for so long. You had no problem cumming in her panties. At the end of the day, is it really that different? I know, why don't you give her a long, passionate kiss, while you cum? Trust me, women love it when men do that!” “O-okay.” Sonic quietly agrees. Aleena uncovers Sonia’s mouth, but quickly uses one hand to squeeze her cheeks together, preventing her from speaking, and puckering her lips. “Go on son, kiss your sister.” Sonic cannot fight his lust, he slowly leans over, and awkwardly attaches his lips to his sister's. “That’s it, there you go. She's going to fight you, so take it as a challenge. Keep your dick inside her, and don't break the kiss.” Sonic's thrusting resumes, at the other end of the bodies, he deepens the kiss, sticking his tongue wherever he can inside her mouth. Sonia tries desperately to move her hips away, but Sonic’s dick stays firmly planted inside of her. “You’re doing it Sonic, she’ll be yours in no time at all. I know you must be close, give her everything you've got, the let it all go!” Sonic was humping her like mad, the pressure inside of him was all but ready to pop. At last, a spark ignited inside of Sonic's balls, lighting the canon that was his penis. Forcing himself flat against Sonia's squirming pelvis, he erupted, firing off a devastating blast of semen, the likes of which she had never experienced before. His twitching member would not stop, Sonia let out a moan of despair into Sonic's mouth, but the reverberations were so pleasurable, it only caused him to spray more of his seed. The sticky white fluid oozed out the sides of her pussy, causing a large pool of cum to form between their legs. 


   Sonia stopped moving, and Sonic pulled his face away from hers, leaving a sloppy trail of saliva behind. “Yes! That was stupendous! You did marvelously my son! You've impregnated her for sure!” “Wait, you wanted me to get her pregnant?” “Well of course, I want to be a grandmother, and this way, we can keep our royal blood pure in all of your heirs!” “Oh...I guess that makes sense. Huh, Sonia looks kinda tired.” Sonia had passed out from the shock, as well as the overwhelming amount to semen inside of her. “Oh dear, she doesn't look like she's ready for another round yet, but you definitely are, aren't you Sonic?” He nods “Sweetheart, what if I said that you could do what you did with Sonia, with me as well?” Sonic pops his dick out of Sonia’s pussy, causing more globs of cum to roll out of her. “Really?! You’d let me fuck you too Mom?!” “Absolutely, but only if you promise to cum inside of me as well.” “Yeah, of course! Cumming inside feel amazing, I'm going to do it every time, with you and Sonia!” Aleena undoes her dress and stands naked before her son. Sonic rushes over to her and frantically shoves his dick inside her. “Good, now fuck me as fast as you can. Mommy wants that cum, now!” Just as she demanded, Sonic thrusts wildly, trying as hard as he can to cum fast for his impatient parent. “Faster sweetie, faster! You need to fill Mommy up with all of your hot semen!” Once again, the floodgates are opened, Sonic shoots another load deep inside of his Mother's pussy, the feeling just as sublime as with his sister. “Very good baby! Your Mommy will be sure to get pregnant with this! Oh my, but you're still hard? I think your sister has rested long enough, go and play with her.” Sonic follows his mother's orders, shaking Sonia by the shoulders to wake her up. Just as she starts to stir, Sonic takes to sucking on her nipples, and rubbing his cock against her entrance. 


   Now awakened, Sonia finds herself a shell of the girl she was before. Her spirit is broken, as her brother fondles her, she has neither the strength nor the will to fend him off. The only option left available to her...is to submit. Day after day, Sonic impales his own sister on his cock, each time loading her up with his thick spunk. Be it in her mouth, on her face, or in her pussy, the result is always the same, Sonic will fuck her until he can fuck no more. Twice a week, his mother will join him, lending her willing cunt to his needy cock. As the months go by, the mother and daughter's bellies grow. “Brother, will you fuck me now?” Sonia sits on her knees, her stomach bursting at the seams with her brother’s children, she will be having twins very soon. This does not stop her from begging for his penis. “You’ve finally finished with mother, so please can it be my turn now?!” Aleena lays on her side, her pussy spewing out her son’s semen. Sonic stands up and looks down at Sonia. “Only if you say it.” He smacks her face with his dick. “I love your cock!” He smacks her again. “I live for your cock!” He smacks her one last time. “The only thing I love more than your cock, is your cum!” He points his dick directly at her face. She takes the hint and begins to suck. “Alright, you win, but only because you're such a good sister Sonia.”


   Meanwhile, at Shadow’s house, Manic and Shadow sit in beanbag chairs, smoking weed and getting high as fuck. “I just don't get it bro, why does my Mom keep kicking me outta the house?! It's a good thing you let me crash here, or I don't know what I'd do man.” “Yeahuh, now bend over.” “Aww come on Shadow, this game always makes my butt hurt. Can’t we do something else for at least one night?” Shadow cracks a whip “If you wanna stay here, we do this every night, thems the rules.” Manic takes another hit and sighs “Alright, fair is fair broham, pound away.” Shadow reels back “The safe word is rutabaga.”
