Taboo Sister Novels & Stories

The day I died was the same day as my twin sister’s birthday party. She was in tears and was wrapped up in my boyfriend’s arms. My mom was seething with anger and kept calling me over and over again. My brother was clearly upset and sent me a text saying, "You’re so selfish. You just can’t stand to see anyone else happy." Even my usually quiet dad was furious and said, "She’s nothing but an ungrateful brat." I touched my chest. Thankfully, it did not hurt anymore.

Aah!“ Jojo groans and pushes Finn away. Her eyes open wide as she looks at him. “Finn? What was that? You are my brother!“ Finn sighs, licking his lips and staring into his eyes. “Am I?“ He asks. He tries to hold himself back from pulling her in and kissing her again. Jojo blinks her eyes in confusion. She lifts her finger and touches her wet lips. “What? You have always been my brother, right? We... we can't do this.” Finn scoffs and leans closer to her again. “Stop being so naive, Jojo. Yes, you are my little sister. But you can be something else, can't you?“ “Something like?“ The more confused Jojo asks, looking into his eyes. But she shudders again. “Brother? Why are you looking at me like that?“ Finn chuckles and holds her chin. “Like what? Isn't it because I want to kiss you again?“ He asks and leans in for a kiss. “Um… Brother…” “Ssh!“ Just at the same time, the door is pushed open, and Vera walks in. Jojo quickly adjusts her clothes. “Your fiancee is here... I'll leave,” she says. But Finn pulls her into his arms and prevents her from leaving. “I want you to stay,” he says, looking up at Vera, whose eyes are teary. “What do you want, Vera?“

“Say it,” he growled, voice low and dangerous, his thick cock buried deep inside me, stretching me so full I could barely breathe. I was bent over the couch in nothing but my collar, thighs shaking, pussy dripping down his balls as he pounded into me without mercy. “I’m your little sister…” I gasped, voice breaking as another brutal thrust made me see stars. “And I belong to you.” Damien’s hand tightened around my throat from behind, pulling me back against his chest while he fucked me even harder. “Louder,” he demanded, biting my ear. “Tell me whose forbidden cunt this is while I breed you.” “It’s yours!” I cried, tears of overwhelming pleasure running down my face. “My step-brother’s pussy… please fill me up… breed your little sister!” He groaned like an animal and slammed into me one final time, flooding my womb with thick, hot cum as I screamed and came harder than I ever had in my life clenching around the cock I was never supposed to take. That was only the first night. ⚠️⚠️ TRIGGER WARNING ⚠️⚠️ This collection is not for the faint of heart.

My mother-in-law was somehow allergic to me. As long as I was in the house, her skin would break out in rashes, and she would struggle to breathe. The hospital could not find any specific allergen. They said it might be something to do with my scent. To give his mother some relief, my husband Keith asked me to stay in a hotel every weekend. I quietly packed away everything that was mine. I even stopped wearing my favorite perfume just so I could stay home for one extra day. However, her condition only grew worse. The days I was allowed to be home dropped from five days a week to three, and eventually to just one. I never complained. I only hoped she would get better soon. One day, I left work early to pick up a document from home. I heard laughter from inside the house. "Mom, your trick really works! Every time you cough, my brother kicks that woman out." It was Keith's god-sister Caroline, who had studied abroad. My mother-in-law laughed smugly. "Caroline, you're the best. You can cook, and you give great massages. You're nothing like that useless block of wood who's always in the way. "Keith, hurry up and marry Caroline already. Get rid of that woman!" Keith's voice was full of indulgence. "Mom, don't say things like that. Caroline, look at the perfume I bought you. You've worked hard lately." All strength left my body as I stood frozen at the door.

As the youngest daughter of the Costellos, I had always lived in my sister’s shadow. That was until five years ago, when she betrayed the family and ran off with a street thug. I took her place and completed the wedding with Elio Ross. Over the years, he loved and indulged me, but we never got a marriage license. He always said family matters kept him busy, and that, with or without it, I was his wife in his and the family’s eyes. I believed him. Until today… I watched as Elio walked out of the church with my sister Alyssa, who had been missing for five years, both of them wearing the family rings that symbolized their union. At the church entrance, three black SUVs opened their doors simultaneously, and my three brothers stepped out in tailored suits. “The ceremony’s done? We’ve already booked Antonio’s to celebrate Alyssa’s return.” They climbed into the cars, expressing their joy, while no one noticed my pale, shattered face across the street. Later that night, under the guise of apology, my sister let a venomous spider bite me. “A substitute is always a substitute. Now that I’m back, it’s time for you to die.” I screamed for help. However, my husband and my three brothers only rushed to hold my sister, who had pretended she had fallen, without a glance at me, writhing from the poison. They called in every specialist from the hospital, only to tend to my sister’s scraped knee. That was the moment my heart truly broke. After being dragged back from death’s door by the doctors, I made my decision. I picked up the phone and called the International Private Island Exchange. “That isolated, uninhabited island… I’ll take it.”

This isn’t a book. It’s a violation. Of your rules. Of your morals. Of the last line between want and ruin. These aren’t stories. They’re commands. Each page is a filthy little dare to spread wider, moan louder, and let go of every ounce of control you thought you had. Because once you start reading? You don’t stop. You can’t stop. This is where innocence gets devoured by the mouths it was told to avoid. Where best friends’ daddies, strict professors, and stepbrothers with no self-control break all the rules in your head—and then break you. They’re not gentle. They’re not careful. They’re not here for love. They want your breath caught in your throat. Your thighs shaking from how much you need it. Your body betraying every thought that says “no.” They’ll pin you down with a stare. Fuck your mind until it spirals. Make you beg without even touching you. You’ll gag on the tension. Cry from the pressure. Climax from the ache of what you’re not supposed to want. So keep your fingers ready. Keep the lights low. And baby? Be warned: You’re gonna need a towel by the end. Because this book doesn’t just seduce you. It owns you. Read it loud. Feel it deeper. And don’t you dare pretend you didn’t love every depraved second of it.
