Also note: There's some homophobic and racist language in here. I am not either of those things, I have never been, nor will I ever be. Hating someone for their race/sexuality/creed/whatever is wrong and incredibly stupid. Don't do it. That said, I apologize if the language offends anyone. I wrote it as part of the characters I created, and I would hope/imagine the real-life inspirations of these characters aren't this way, either.
Soapbox done, on with the story:
*****
"Frankie? I'm home!" Ariana Grande called out, stepping into the home she shared with her older half-brother. Dressed in a blouse, skirt, and flip-flops, the 21-year-old pop star had just come back from several business meetings she had had throughout the day. The meetings had gone well, but Ariana often found them tedious, particularly if the people involved were dry as dust. Today had been one of those days, and by the end of it Ariana couldn't wait to get home and spend time with her brother. She had already sent her entourage and bodyguards home for the evening, and her mother was dogsitting for the next few days, leaving the house entirely to the two of them.
Pausing to drop her things off in her living room, Ariana could hear the shower running upstairs. Smirking, she slipped off her flip-flops and padded barefoot up the stairs until she reached the bathroom. Pushing open the bathroom door, Ariana was greeted by the familiar sight of her nude half-brother, his back to her as he stood under the hot shower. Through the clear plastic shower curtain she could see that he was soaping himself up, working it into lather over his athletic frame. He bent over to work the soap over his legs, and Ariana couldn't help but lick her lips as she gazed shamelessly at his well-toned ass. She could feel herself getting hot, and not just from the heat of the shower.
Now Frankie was straightening up, still facing away from the door, and Ariana saw his right hand move towards the lower front of his body—he was giving his cock and balls a good, thorough wash. It was soon clear that this wasn't all that he was doing, as she saw his arm start moving back and forth and Ariana heard him grunt with pleasure. His head tilted back, and though she couldn't see them, she was sure his eyes were closed. Clearly Frankie was starting to jerk himself off to whatever homoerotic fantasy was playing out in his head.
Gingerly stepping into the bathroom and closing the door quietly, Ariana slowly moved over to the shower until she was standing right behind him, with only the shower curtain separating them. Ariana took hold of the edge of the curtain, waited a few moments to let Frankie get into a rhythm, and then yanked the shower curtain aside.
"Jesus!" Frankie spun around, soap and water spraying everywhere. Ariana giggled as he nearly lost his balance and fell on his ass. "Fuck, Ari, don't do that!"
"What's the matter, Frankie?" Ariana said in a playfully mocking voice. "Did I take you out of your fantasy of sucking Bieber's skinny little cock?"
"Fuck you, shrimp," Frankie responded, regaining his balance so he stood over his half-sister at his full height. "That little bitch's baby dick couldn't satisfy a stuffed animal." He had stopped masturbating, but made no attempt to cover himself, instead letting Ariana look at his naked, soaking body. Ariana's eyes were immediately drawn to her desired prize: Frankie's 10-inch long cock, over an inch thick in the middle and fatter at the base, with a bulbous head at the other end. Below it hung two heavy testicles the size of golf balls. Frankie kept his groin shaved so that his sexual equipment stood out clearly, and against his dancer's body frame it looked like a kielbasa sausage. Right now it was at full attention and Ariana could see pearly drops of precum in the piss-slit.
Being a devoted sister meant that Ariana loved her sibling for who he was, both inside and out. Being a dirty-minded slut meant that she especially loved his huge cock. Fortunately for her, Frankie was just as much of a pervert as she was, and even though he preferred men over women, he took exception to Ariana, who had an incredibly snug cunt and asshole and from certain angles (or if he was drunk enough) could pass for a twink with her five foot build, small A-cup tits, and slender hips. Besides, nothing turned the two on more than knowing that every time they fucked, sucked, or otherwise pleasured each other they were engaging in the extremely taboo act of incest.
"Well, something's got you all hot and bothered," Ariana teased with a wicked grin, folding her arms across her chest. "C'mon, 'fess up—what kinda fag fantasy were you jacking off to?" Ariana was by no means a homophobe, but she knew dirty and derogatory talk turned Frankie on sexually, just as it did with her.
Sure enough, Frankie resumed stroking himself leisurely, not taking his eyes off of Ariana's challenging ones. "Actually, I was thinking about you and Sean," he said. "Has he gotten you to lick his dirty black ass clean after he takes a shit?"
"Fuck you, asshole!" Ariana replied, but she was smiling, and gave him a light slap on his chest. "You just wish you were the one doing the licking instead of me."
"Damn right, I do," Frankie said, increasing his strokes a little bit. "I'd spit-shine that asshole before starting in on his nigger cock—I saw you two fucking the other day, and damn, he really is "big" Sean. Blew my load as soon as he did."
"I knew you were watching!" Ariana exclaimed, slapping his chest again. "You sick fuck, jacking off to your sister having sex!"
"And now you're watching me jack off in the shower," Frankie shot back. "So who's the sick fuck now?"
Both of them were breathing heavy now, and the air in the room was charged with wanton lust. The two siblings could sense it was about to happen and they locked eyes, waiting to see who would break first.
Ariana reacted a split-second before Frankie did, reaching up to undo her blouse and opening up the first button before Frankie grabbed her arm and pulled her under the steaming shower spray. She squealed, first at the sudden spray of water hitting her face, and then again when Frankie ripped the blouse open and off her shoulders, buttons scattering over the floor. Ariana wasn't wearing a bra and her tits were soaked in seconds. "Dammit, Frankie, that blouse was new!" Ariana started to protest before Frankie grabbed her small tits in two handfuls and pulled her close in a crushing, passionate kiss, shoving his tongue into her mouth.
Ariana responded with equal passion, her tongue meeting his in a frenzied, slippery dance, her hands reaching down to grasp his cock in both her small hands. She jerked his cock, running her hands up and down while squeezing it in particularly sensitive spots. The two siblings made out under the shower for a few minutes, water cascading over them, before Ariana, still locking lips with Frankie, bit down on his lower lip.
Frankie stiffened and tried to pull away but Ariana held his head in place, biting down harder and drawing blood. It was only when he began crushing her tits painfully in his hands that she let him go, and he pulled away, a trickle of blood running from his chewed lip. "Fuck, Ari, what the hell?" he demanded, spitting the blood onto the shower floor.
Ariana massaged her aching tits, though she had a predatory smile on her face. "That's what you get for ruining my new clothes," she said, referring to her torn blouse, which was now a soaking mess on the floor, and her skirt, which was still on her body but just as drenched.
Without warning Frankie let loose with a hard slap across Ariana's face, the sound of it loud even under the pounding water. Ariana's head whipped around, her drenched hair sending an arc of water flying, and she clutched the wall for support. "That's what YOU get for being a little cunt!" Frankie retorted.
Ariana turned back to face him, and Frankie could see that her lip was split open in a similar fashion to his, with blood running down her chin. She spat blood onto the floor and looked at her brother, breathing heavily, the perverse, predatory grin still on her face.
Without another word Ariana stripped off the ruined skirt and tossed it aside just as Frankie came forward and bodily pushed her up against the bathroom wall, her back on the wet tiles. He wasted no time in positioning his straining cock at the entrance to her cunt, and penetrated her with a single hard thrust, beginning to fuck her roughly like a wild animal.
