Stepbrother Rules- 1

My phone rang while I was folding laundry. It was Mom.

“Baby, I got married today!” she squealed, sounding happier than I’d heard her in years. “Richard and I just did it at the courthouse. We’re flying to Bali tonight for our honeymoon, two whole weeks. Pack a bag and head over to the house. Your new stepbrother Jax is there. Be nice, okay? I love you!”

She hung up before I could respond. I stood there staring at my suitcase, completely stunned. Married? Just like that? I barely knew Richard existed two months ago. Now I had a stepdad and a stepbrother I’d never even met.

The next evening I drove up to the Voss mansion. The place was huge, all glass walls and sharp modern lines, sitting high on the hill with a view of the city lights. A maid let me in and showed me to the dining room.

That’s when I saw him. Jax was standing by the tall windows, looking out. When he turned around, my heart skipped. He was beautiful. Tall, broad-shouldered, with dark hair that fell just right and intense blue eyes that locked onto me. His black button-down was open at the collar, sleeves rolled up, showing tattoos running down his strong forearms. He had this quiet, confident energy that made the room feel smaller.

My stomach did a strange flip. A rush of heat hit me, did I celibate that long that seeing a hot guy made me horny. Snap out of it, this is your brother.

“Riley,” Richard said warmly, pulling me into a quick hug. “This is my son, Jax. Jax, meet your new little sister.”

Jax looked at me for a long second. His eyes moved over my body, but his face stayed completely calm, no smiles. Just a flat, polite nod.

“Hey,” he said. “Nice to meet you.”

That was it. He turned back to the window like I didn’t matter.

"What an asshole," I mumbled. "Rileyy.." mom warned me, I responded a smile that didn't reach my eyes.

Dinner was ordinary. Richard and Mom couldn’t stop smiling at each other. They talked about their trip, the food, how lucky they felt. Jax ate quietly, answering questions when asked but mostly staying silent. I tried talking to him, asking about his job, his hobbies, but he gave short answers and went back to his plate.

The only weird part was how touchy Mom and Richard got as the night went on. His hand kept disappearing under the table. Mom would giggle and bite her lip. At one point she leaned over and kissed his neck right there. The air felt thick. Jax and I both pretended not to notice. Our eyes met once. Something hot passed between us, then we both looked away fast.

After dessert, Richard stood up. “We should head to the airport. You two bond while we’re gone. The house is yours for two weeks. Maids will handle everything else.” I was a little confused, "I thought it was a vacation for the four of us, where are you two going?" "Your mom and I figured you and Jax should bond as siblings to reduce the awkwardness." Richard answered instead

Mom hugged me tight. “Be good, sweetie. Love you!”

And just like that, they were gone. The big house suddenly felt very quiet. I helped clear the last dishes. Jax carried some plates to the kitchen without saying a word, then disappeared upstairs.

That night I couldn’t sleep.

I tossed and turned in the guest room bed, the sheets feeling too warm against my skin. When I finally drifted off, I fell into a dream so vivid it felt real.

In the dream, I was back in the kitchen. Jax had me pinned against the marble counter, his big body pressed against mine. His hand slid up my thigh, pushing my dress higher. He ripped my thong aside and pushed two thick fingers deep inside me without warning.

“You’ve been teasing me all night,” dream-Jax growled in my ear, voice low and rough. His fingers curled perfectly, stroking that spot that made my knees weak. “Now you’re going to take what you started, little sis.”

I moaned loudly in the dream, gripping the counter as he finger-fucked me hard and fast. The wet sounds filled the kitchen. He bit my neck, then kissed me roughly, his tongue claiming my mouth while his fingers drove me closer and closer.

“You want your stepbrother’s cock, don’t you?” he whispered, adding a third finger, stretching me. “You want me to bend you over and ruin this tight little pussy right here where our parents just had dinner.”

I cummed hard in the dream, crying out his name as my body shook. But he didn’t stop. He pulled his fingers out, turned me around, and bent me over the counter. I felt the thick head of his cock press against my entrance, then he thrust in deep in one smooth stroke, filling me completely.

He fucked me hard, one hand fisting my hair, the other slapping my ass. “Say it,” he growled. “Tell me you belong to your stepbrother now.”

“I’m yours,” I moaned in the dream, pushing back against him. “Fuck me, Jax. Please—”

I woke up gasping, heart pounding, my panties completely soaked. My pussy was throbbing, aching with need. I lay there in the dark, breathing hard, embarrassed by how turned on I was.

It was just a dream. But it felt so real.

The next morning our parents had already left. A note on the fridge said they’d landed safely and hoped we were “getting to know each other.”

Jax was in the kitchen when I came downstairs, drinking coffee. He looked even better in the morning light, black t-shirt stretched across his chest, sweatpants hanging low on his hips.

“Morning,” I said, trying to sound normal.

He gave me a small nod. “Morning.”

The silence felt heavy. The big house was completely ours for two weeks. No parents. No rules except the ones we made.

I poured myself coffee and leaned against the counter, watching him. That urge from yesterday was still there, even stronger now after the dream.

How the hell was I supposed to survive fourteen days.
