Stepbrother Sex Novels & Stories

Adeline It was so fucking wrong. So wrong. Sleeping with my stepbrother. Aching for him to fuck me. Waiting for him to come home every night to take me. Fuck me so hard before filling me up with his thick hot cum. I was such a whore for my stepbrother and the thought alone made my thighs clench. It made me want to bounce on his cock right now while he fucks me raw. When we got home from one of our many family bonding times -- where we take pictures and send them to the parents, José pushed me into my bedroom, pressed me against the door, and ground his cock into me from behind.

"Late night at the mansion? Or did the 'Step-Sister' role turn out to be more work than you expected?" "I'm not in the mood, Sienna," I said, my voice flat. I jammed my English Lit textbook into my bag. "Oh, I bet you aren't. It’s hard work, isn’t it? Trying to fit into a world where you don’t have a receipt." She stepped closer, her voice dropping so only I could hear. "I saw the way you looked at Roman this morning. It was pathetic. You looked like a stray dog waiting for a scrap." I gripped the edge of my locker door until the metal bit into my palms. "He’s my step-brother, Sienna. We live in the same house. Of course I’m going to look at him."

His sculpted, tattooed body was still slightly damp from a recent workout, muscles flexing with each step. Our eyes locked across the foyer. Shock flashed across his handsome face, quickly replaced by raw, burning heat—the same heat from that wild night in Vegas. This was his house. His father was now my stepfather. Which made the man who had fucked me senseless in Vegas just one week ago… my new stepbrother.

Having sex with my stepbrother is something I never thought I’d do. Yet here I was, on Thanksgiving night in Grandma’s creaky old guest bed, legs spread obscenely wide while Marcus slammed his thick, veiny cock balls-deep into my dripping wet pussy. The wet, filthy slapping sounds of his heavy balls smacking my ass filled the small room, mixing with my muffled moans and his low, dirty growls.

It felt as though he had been possessed by a dark and dangerous demon, or was he always like this but didn't show it? “You haven't met him for the past few years, you don't expect him to be the same when you meet him again” A voice chipped into my head, I heaved a sigh and turned to the other side of the bed. My endless encounter with so many people who never cared for me and planned to use me has made me suspicious of my only brother. Although he was my stepbrother, he protected me like I was his blood sister back then. I could never forget his unwavering love towards me then.

It felt strangely unfair that the world could keep moving so normally while mine had flipped upside down in less than forty-eight hours. The weight of keeping it all inside felt too heavy to carry alone anymore. I let out a ragged breath and rubbed the back of my neck. "No. The stepfather is fine. He's actually an old neighbor from when I was a kid." I took a shaky breath, finally dropping the real news. "And apparently, I have a stepbrother now." Leo stopped chewing mid-bite. He blinked, swallowed hard, and nearly choked on his drink, slamming the plastic cup down onto the table.

“Then stop teasing and make me come already.” He dropped to his knees right there on the gym floor, yanking my shorts down. His mouth was on me in seconds. I threaded my fingers through his dark hair, trying not to cry out as he took me deep, throat working around me. The sight of my serious, bad-boy stepbrother on his knees for me was almost enough to finish me off. “Fuck, Liam… I’m close…”

He probably forgot because there's no way he'd just sleep with me if judging by what he has right now, he can get any girl he wants. "I didn't expect that we would meet again under these circumstances." Wow, how could he said that so casually? It's fine if he thinks it's just a one-night stand, but doesn't he feel awkward because we're about to become family? "I hope you don't say anything to our parents about what we did last night. Let's pretend that nothing ever happened between us. So let's forget the past and in the future we'll be a harmonious family, me as your stepsister and you as my stepbrother."

I exhaled slowly, pushing off the doorway, ready to lock myself in my room for the night, when a low chuckle stopped me. “You should have at least pretended to care,” Nathan’s voice drawled lazily from the couch. I turned my head, glaring at him. My stepbrother lounged with a cocky grin, his long legs spread out, an expensive whiskey glass in hand. He was everything I despised—rich, arrogant, and born with a silver spoon in his mouth. His dark hair was tousled, his sharp features unfairly attractive, and his eyes, a shade lighter than Ethan’s, danced with amusement.

but it left as quickly as it came. She parted her legs wide, exposing herself completely to me, to him. Her unshaved pussy glistened, already dripping. I could not believe what I was about to witness, a sexual act between my stepbrother and my sister. I pushed against the chair, tears slipping free from my eyes. I tried to scream, to cry for help, but it was all just jumbled nonsense against the damn tape. "You should not have been nosy, Sarah. You should not." He stood sideways, letting me watch as he unbuttoned his jeans, then unzipped slowly.
