Scamming The Besotted Billionaire

[Ava] "You're a much better f**k than your prude of a sister, you drunk slut," a familiar voice tore through my apartment, moments after my arrival. At least I thought it was a familiar voice. My fiancé's voice. I shook my head. I was wrong. Just like every other time. Of course I was. "f**k, aah, yes," Aria moaned as I made my way through the one bedroom I shared with my fiancé, Jason. "For f**k's sake, Aria," I muttered under my breath with a sigh. "f*****g boundaries. Stop making me part of your f****d up s****l fantasies," I groaned. Supermodel Aria Monroe was my twin sister. I loved her to death, but she was also a slut. No two ways about it. Her recent rise to B-list model status made the situation worse. Being in her life and looking exactly like her was my curse. This was made worse by her creepy kink of men berating me while praising her in bed. The worst part? She was probably f*****g some loser who couldn't spell his own name right. In my and Jason's bed. While pretending he was Jason. It just gave me the ick. "Pulling this s**t in my apartment is a new low, even for you Aria—" I was trying to yell through the bedroom door, but she bested me, her howling drowning me out. That was the f*****g last straw. I was throwing her ass and her loser hook up out, dead of the night or not. "Yes, Jason, yes. f**k me like you f**k your fiancé. My sister. f**k my p***y like it's Ava's. God that's good," Aria continued to moan as I turned the doorknob, buzzing with the anticipation of calling her out for the umpteenth time. I couldn't take it anymore. Paranoia set in. She was officially not allowed around Jason unless I was present because f**k, she was a freak. Once the door opened, my heart stopped, then plummeted into my stomach. The breath caught in my throat. All I wanted to do was drop into a heap and cry forever. Because how f*****g could they? Some part of me always wondered. Was it possible that Jason was f*****g my sister behind my back? So why was I still shocked by what I saw? Too stunned for words, my eyes instantly squeezed shut. Every single time I heard her calling out my fiancé's name in an alleyway or the back of a car seat with her legs spread I told myself it was just a fantasy. My train wreck sister was just expressing her f****d up fascination with my life and the stability I had achieved. Coveting it. I was a logical person. Becoming a lawyer made it an occupational hazard. My mind would never believe unless it had proof. So I forced my eyes open and made myself look. It was not my mind playing tricks. There my doppelganger was, bouncing and down my fiancé's d**k. I felt so stupid. Humiliated. Defeated. Of course they were f*****g each other. They spent more time together than Jason and I did these days. How many times did he f**k her? How f*****g long? My whole life. Aria and I shared everything, even on occasion her career, but that wasn't enough. She had to have everything I did. Including, apparently, my fiancé's d**k stuffed into her p***y. "f**k me like I'm my sister. Just like you f**k her. Damn it, taking things from the pushover is fun," Aria said, a sickening giggle tumbling from her lips. "She would probably have given you to me if I asked, but taking you is so much better." "f*****g w***e. Is this what all my sacrifices to keep your career alive are to you? A joke? Am I a f*****g joke?" I hissed under my breath, my hands turning into fists at my sides, while my blood boiled. No matter how much of a needy, flaky slut she was, I always helped out by taking Aria's place when she was too black out drunk to show up for work. I did it because I thought sisterhood meant something to her. Clearly I was mistaken. Never in my wildest dreams would I have seen this coming. Fuck the f*****g tears filling up my eyes, making me wonder if somehow I could have done something to prevent this. Did I not do enough for her? Did I hurt her somehow? Why could she never just be happy for me? Not one, but the two single most important people in my life, were actively in the process of hurting me. Breaking my trust. The man I gave my heart, innocence and greater part of my twenties to, was f*****g another woman. One I cared about. Couldn't get rid of. He f*****g knew that. He didn't even have decency to f**k her somewhere else. I am standing right in front of you while you f**k her, I wanted to scream, but words failed me. It was like they couldn't see me. Like I might as well not exist. Still I couldn't look away as they pissed away my faith in them for a f**k. Jason spoke and the betrayal hit me all over again, like seeing them go at it was fresh information. "I always wanted to f**k you both, but she's too stiff to agree to a threesome," Jason mused, slapping Aria's ass as she went to town on his d**k. She giggled in between pants like riding my fiancé in my bed was the funniest thing in the world. IN. MY. f*****g. BED. "What the f**k do you need her for? I'm a lot more fun, aren't I? She doesn't know how to take care of a man's d**k. We should have started f*****g in your bed years ago. This s**t is so f*****g hot," a giddy, out of breath, Aria squealed with glee. "She takes care of our bills and does your job more often than you. So keep your w***e mouth shut and your slutty legs open. f*****g traitorous, sexy b***h," Jason panted, humping up into Aria like he hadn't gotten laid in months, a satisfied groan erupting from him. He was red in the face and sweating like a pig. f*****g asshole. Where was all that effort and consideration when he was in bed with me? "Ssssssshhhhh. We won't say a word. Just keep f*****g me behind her back. Little miss perfect is so busy saving the world she will never even notice," Aria cooed, another string of giggles pouring out of her as her back arched. She exaggerated her enjoyment, then cried out, "Cuming. I'm cuming. I'm cuming." Definitely a fake orgasm. f**k knew in that moment, just for a second, I pitied her (and me) for being hard up for Jason's puny d**k.
