(Isabella's pov)
We lay tangled in my messy sheets, bodies glistening with sweat, the room heavy with the scent of s*x and our mingled breaths. My heart hammered wildly as Jack’s hands continued roaming my curves — possessive, tender, and hungry all at once.
The emotional weight of what we were doing pressed down on me: the guilt of betraying our family by f*****g my stepbrother, the terrifying realization that I was falling deeply in love with him, and the shameless, burning lust that made my freshly-f****d p***y throb and leak with need for more.
“I still need you so badly,” I whispered against his lips, my voice husky and desperate. “I don’t want tonight to end. I want you to use me, Jack. Make me your dirty little stepsister slut.”
Jack’s deep blue eyes burned into mine, filled with the same chaotic storm — love, guilt, and raw desire.
“f**k, Izzy… I’m falling in love with you. This is so f*****g wrong. You’re my stepsister, but I can’t stop craving your tight, dripping cunt. Tell me exactly what filthy things you want your stepbrother to do to you tonight.”
Heat flooded my face, but the words poured out. “I want you to watch me finger my own p***y first. Then I want you to f**k me senseless with your big c**k. I have a vibrator in my nightstand drawer… use it on my c**t while you pound my cunt.”
Jack’s thick c**k twitched visibly at my vulgar request. “You filthy, perfect girl. Get the vibrator right now, then spread those legs wide and show your stepbrother how you play with that slutty little cunt when you think about me.”
I quickly retrieved my small pink vibrator and handed it to him. Then I lay back on the bed, spreading my thighs obscenely wide, my soaked, puffy p***y completely exposed. My fingers slid down to my dripping folds.
“Like this?” I asked breathlessly, circling my swollen c**t before pushing two fingers deep inside my greedy hole with a wet squelch.
“f**k yes,” Jack groaned, slowly stroking his hard c**k as he watched intently. “Finger that p***y deeper, baby. Stretch it open for me. Show me how wet and sloppy you get thinking about your stepbrother’s thick d**k ruining you.”
I pumped my fingers faster, moaning loudly as obscene wet sounds filled the room. “I always think about your c**k when I do this,” I confessed shamelessly. “I imagine you f*****g me hard, filling me up, making me scream. Oh god, Jack… I’m so f*****g wet for you right now. My p***y is dripping.”
He turned on the vibrator and pressed the buzzing tip firmly against my sensitive c**t while I kept finger-f*****g myself. The intense vibrations made my hips buck wildly. “That’s it, you dirty little stepsister w***e,” he growled. “f**k your fingers while I vibrate your swollen c**t. Look how your cunt is gushing all over the sheets like a desperate slut.”
The combination of his vulgar words, my own thrusting fingers, and the relentless toy pushed me toward the edge at lightning speed. The tension coiled tighter and tighter in my belly. “I’m going to come so hard,” I whimpered. “Watch me come for you, Jack. Watch your stepsister’s p***y explode.”
“Come hard, baby. Squirt on your fingers for your stepbrother. Let me see that greedy cunt gush like the filthy girl you are,” he commanded, pressing the vibrator harder against my c**t.
I exploded with a loud, broken cry, my walls clenching violently around my fingers as a powerful orgasm ripped through me. Juices gushed out, soaking my hand and the sheets. Jack watched with dark, hungry eyes, then pulled my hand away and sucked my glistening fingers clean, moaning at the taste. “Mmm, you taste so f*****g good. Such a sweet, slutty cunt.”
He handed me the vibrator. “Keep it pressed on your c**t, baby. Don’t you dare move it.” Then he lined up his thick c**k and thrust into my soaked p***y in one powerful, deep stroke.
“Oh fuuuuuck!” I screamed, my back arching. “Your c**k is so big! It’s stretching my tight cunt so good! f**k me, Jack! Destroy my p***y!”
He pounded me mercilessly, his hips slamming against mine with wet, obscene slaps. “Take that d**k, Izzy. Your stepbrother is destroying your little cunt. You love it, don’t you? Say it like the dirty girl you are.”
“Yes! I love your big c**k f*****g my p***y!” I moaned loudly, holding the vibrator firmly on my c**t. “Harder! Ruin me! Make me your dirty stepsister slut! Pound my cunt!”
Jack f****d me relentlessly, the vibrator making every brutal thrust feel electric and overwhelming. “Your cunt is gripping me so tight,” he groaned. “So wet and hot and perfect. I’m falling so f*****g hard for you, even though this is so wrong. I can’t stop wanting to breed this pussy.”
His raw confession, mixed with the filthy pounding and the buzzing toy, pushed me over the edge again. “I’m coming! I’m coming so hard on your c**k!” I screamed as another powerful orgasm tore through me, my walls milking him tightly.
Jack thrust deep and groaned loudly. “I’m gonna fill this p***y up.” He came hard, his c**k pulsing inside the condom as he held me tight, both of us shaking.
We stayed locked together afterward, kissing tenderly through the aftershocks. The emotions hit us both hard — love, guilt, satisfaction, and the terrifying knowledge that we were completely addicted.
“I don’t regret any of this,” he whispered, stroking my hair gently. “You’re worth all the risk in the world to me.”
“I’m yours,” I replied softly, snuggling into his chest. “And I still want so much more of you tonight.”
Jack kissed my forehead with a wicked, loving smile. “Good. Because we’re far from finished, baby.
