What My Stepbrother Did When We Were Left Alone

The first week of April always brought that strange quiet to the house. My parents—in reality, my mother and Adrián’s father—took advantage of the Easter break to get away somewhere with a pretty name and a room with a jacuzzi. They’d been doing it ever since they got married, three years earlier. It was a habit I had learned to ignore the same way I ignored the hum of the heater or the creak of the third stair. Something that simply happened.

That Thursday afternoon, when I got home from work, I found the house silent. That was normal. What wasn’t normal was Adrián in the living room, sitting on the sofa with a book open on his lap, looking up at me as soon as my keys hit the lock.

“You’re back,” he said, closing the book slowly.

“What are you doing awake? It’s almost ten.”

“Waiting for you.”

I dropped my bag on the hall chair and looked at him. Adrián had that irritating habit of saying completely ambiguous things with total naturalness. Three years living under the same roof and I still couldn’t fully figure him out. He was four years older than me, worked in engineering from home, and had that only-child tendency to fill the space of any room without seeming to try. He rarely bothered me. That night I went on alert immediately, though I couldn’t have said why.

“For what?” I asked.

He got up from the sofa with a slowness I didn’t like. He crossed the living room until he was less than a meter from me, and then I saw what he’d been hiding behind his back. A rope. Fine, braided cotton, the color of dry sand.

My stomach tightened.

“Adrián,” I said, and my voice came out weaker than I’d intended.

“Relax,” he replied, with a smile that was anything but reassuring.

***

I should have said no. I should have grabbed my bag and called my mother. But the truth—the one it’s hardest for me to admit even now, weeks later—is that I didn’t do any of those things. I stayed still while Adrián came closer, and when he took my left wrist between his fingers with measured firmness, I only arched an eyebrow.

“What is this supposed to be?” I asked.

“A game,” he said. “If at any moment you want me to stop, I’m serious, all you have to do is say so.”

I looked him in the eyes. There was something there I hadn’t seen before, or maybe hadn’t wanted to see. Focus. Determination. And beneath all that, something warm that made me swallow and squeeze my thighs together without meaning to.

“This isn’t a normal game between stepsiblings,” I said.

“No,” he admitted. “It isn’t. I’ve spent three years thinking about how to pry your legs open, so no, it’s not a normal game.”

The sentence shot through me like a jolt. I felt my pussy go wet all at once, soaking my underwear before he’d even finished speaking. The rope was soft when he wound it around my wrists. A firm knot, not brutal. Done with practice, which raised a question I decided not to ask him yet. He led me down the hallway toward the stairs with a hand on my back, unhurried, as if we had all night. Which we did.

Adrián’s room smelled like him: wood, printed paper, and something warmer I couldn’t quite name. He made me sit on the edge of the bed and for a moment he simply watched me, standing in front of me with his arms crossed and a very clear bulge straining the fabric of his pants.

“You haven’t looked at me in months,” he said.

“I look at you every day,” I protested.

“You look at me. That’s not the same. Tonight you’re going to really look at me. You’re going to look at me while I fuck you.”

He was right, and we both knew it.

***

What happened in the minutes that followed was slow and deliberate, which is the worst kind of torture. Adrián tied the rope from my wrists to the headboard with a knot that would give if I pulled in the right direction—I checked immediately, almost without meaning to—but that I wasn’t going to loosen without his help. Then he stepped over to the desk and leaned against it, crossing his ankles, studying me from a distance.

“Are you scared?” he asked.

“No.”

“Should you be?”

I considered the question more than I wanted to admit.

“I don’t know yet,” I finally answered.

That made him smile. And that smile was the first time he seemed genuinely dangerous to me.

He came closer again. He started with the buttons on my shirt, one by one, taking as long as he wanted. His fingers didn’t tremble. Mine, with my hands tied above my head, did. Not from fear, or at least not only from fear. There was something else I still didn’t know how to classify: a kind of electric tension running through my arms and straight down to my pussy, which was already throbbing so hard I was sure he could notice.

When the shirt fell open, he let his eyes roam over what was underneath without any hurry. That silent inspection made the heat rise to my cheeks before anywhere else.

“You’re exactly how I imagined,” he said. “And I’m sure you’re already wet. Right?”

I didn’t answer. I didn’t need to. He slid a hand along the seam of my skirt, moved up the inside of my thigh, and pressed two fingers right against the fabric of my panties. I was drenched. Adrián let out a low, satisfied laugh.

“Soaked,” he said, almost to himself. “Soaked little stepbrother fucktoy.”

The word cut through me from top to bottom. I closed my eyes.

“How long have you been imagining it?” I asked, my voice hoarse.

“Since our parents got married.”

Three years, then. Three years of family meals, of watching TV together, of crossing paths in the bathroom in the mornings. Three years in which neither of us had said anything, and in which I had built a version of him that was clearly incomplete.

His hands at my waist brought me back to the present. He unclasped my bra with more skill than I’d expected, and when the garment was set aside, he bent his head toward my neck. His mouth was warm and moved without haste, tracing a slow line from just below my ear to my collarbone. A shiver ran down my back. He lowered his lips to my tits and sucked one nipple fully into his mouth, tugging it with his teeth until he tore a moan from me that I no longer bothered to swallow. He moved to the other, licking it slowly in circles, then bit that one too, harder this time.

“Fuck,” I gasped.

“That’s it,” he murmured against my skin. “I want to hear you say worse things tonight.”

I closed my eyes. This is wrong, I thought. And then I thought something else.

***

Adrián was methodical. Not in the cold sense of the word, but in the sense of someone who has thought about something a lot and wants to do it right from the start. Every caress had intent. Every pause was deliberate. When his lips went back to my tits, sucking and biting alternately, I had already stopped thinking about anything other than the next movement of his mouth.

He yanked my skirt off and my panties went after it, dragged down by his fingers with cruel calm. I was left naked, tied to the headboard, legs spread by instinct because there was no way to close them without looking even more ridiculous than I already felt. He was still dressed. That imbalance made me wetter still.

“Look at you,” he said. “All open for your stepbrother.”

“Shut up,” I whispered, with no conviction at all.

He knelt between my thighs and opened the lips of my pussy with his thumbs, looking at me as if he were studying a map. Then he lowered his face and licked from bottom to top in one long, slow stroke that ended on my clit. I arched my back off the bed as if I’d been shocked.

His hands learned quickly. They learned what made my fingers tense against the rope and what pulled that involuntary sound from me that I was embarrassed to hear myself make. And when he learned something, he repeated it patiently, never losing the thread. He sucked my clit, let it go, buried his tongue inside me, pulled it out, went back to my clit. He slid two fingers in and curled them upward, searching for the exact spot, and when he found it I knew because my cunt clenched around his fingers as if it had a will of its own.

“Stop,” I said at one point, when the heat between my thighs became impossible to ignore.

Adrián stopped at once, lifting his head. His chin was glossy.

“Do you want me to stop completely?”

“No,” I admitted, teeth clenched. “I want you to keep going. But more.”

“More how?”

“Harder. Deeper. I don’t know. Keep going.”

The curve of his mouth was the closest thing to victory I’ve ever seen on anyone.

“Not yet,” he said.

And he continued exactly as before.

His hands explored every part of me with deliberation. When he slid his fingers between my thighs again, I was already so tense that the slightest contact made my back arch off the bed. Adrián found the exact rhythm instinctively, alternating between direct pressure and brief relief, taking me to the edge and backing off just before I could cross it. He sucked, let go, fucked me with his fingers, stopped. I pulled on the rope until my wrists burned, and he watched me fight with myself with unbearable calm.

Once. Twice. Three times.

By the fourth I was begging, which I hated and couldn’t stop.

“Adrián, please,” I said, and his name sounded like a question and surrender at the same time. “Let me come. Let me come, fuck.”

“What do you want?”

“You know what.”

“Tell me.”

I’m not going to say it, I thought. And then I said it.

“Fuck me. Put your cock in and fuck me already.”

***

When he finally untied the knot from my wrists, he did it so he could reposition me with my hands free on his shoulders. It took me a moment to readjust to having my arms loose. They ached a little, though the knot had never been too tight. That detail—the precision of how much to tighten—told me something about him I wouldn’t have been able to articulate exactly.

He stripped fast, without ceremony. When he pulled his pants down, his cock sprang hard against his stomach, thick and already shining at the tip. My mouth watered. I reached out and wrapped my fingers around it, squeezing, and he let out a slow breath. I leaned forward and took him into my mouth as far as I could, sucking the tip first and then moving lower. Adrián grabbed my hair, not to force me, only to hold me, while I licked his whole cock from base to tip and took it back deep into my mouth. He tasted like salt and hot skin.

“Fuck, little sister,” he gasped. “You suck cock like a whore.”

I smiled with a mouthful of cock. I kept sucking until he pulled me away gently, yanking me back by the hair.

“Lie down,” he said. “Now.”

I obeyed. He opened my legs with his knees and set the tip of his cock against my pussy, rubbing it up and down over my lips without putting it in yet. I pushed my hips toward him, searching for it. Adrián laughed softly.

“Ask for it again.”

“Put it in me. Please. Adrián, put it in me now.”

The weight of him on top of me was different from how I’d imagined. Warmer, more real. When he entered me, he did it slowly, unhurried, giving me time for everything. I felt every centimeter slide in, my cunt stretching to fit him, until he was buried to the hilt. I moaned in a way I didn’t recognize. The room was almost dark, only the hallway light slipping in under the door. Enough to see his face.

“You’re so tight,” he murmured.

“Move,” I begged. “Move, fuck.”

He started fucking me with long, controlled thrusts, pulling almost all the way out before burying himself again. Every удар drew a gasp from me. I dug my nails into his back and he sped up, changing the angle, bracing one hand on the headboard to drive deeper. The bed started hitting the wall in a rhythm we didn’t bother to hide.

“Turn over,” he said suddenly, slipping out of me.

I did it without arguing. I got onto all fours and he positioned himself behind me, gripping my hips. He drove back in with one hard thrust and I cried out into the pillow. He fucked me hard, his right hand on my hip and his left squeezing my ass, spreading me apart as he sank in again and again. He dragged a finger wet with spit over my other hole, pressing without quite entering, and my cunt clenched around his cock in a way that made him growl.

“Ah, you like that,” he gasped. “You like it when I touch you there.”

I didn’t answer. No need. He was thrusting so hard I could only moan into the sheet, mouth open, saliva running down my chin. We found a rhythm quickly, as if our bodies had been anticipating this without either of us knowing. His hands guided without forcing. My forehead against the pillow. The sound of our breathing filled the room that smelled of wood and paper and sweat and sex and something new I was never going to be able to ignore again.

“Lie down again, on your back,” he said. “I want to see your face when you come.”

I turned over. Adrián drove in again, this time with one hand on my throat, squeezing just enough. The other dropped to my clit, rubbing circles in time with his thrusts. I felt the wave rise all at once, with no warning possible.

I came with a sound I hope I didn’t make, but clearly did, because Adrián buried his face in my hair and said something very low that I didn’t fully understand. My cunt pulsed around his cock in waves and he kept thrusting until he went rigid, drawing back at the last second. He pulled out and came across my stomach and tits in hot spurts that splashed all the way to my collarbone. I watched him do it, panting, hair stuck to my forehead and legs still trembling.

I didn’t ask him to repeat what he’d said. When he was done, we lay there without moving for a while, listening to the house. Adrián ran a finger through the semen dripping between my tits, gathered it, and put it on my lips. I opened my mouth and sucked it off without looking away.

Then he rolled to one side. I looked at my wrists—no marks, the knot had been exactly as firm as it needed to be—and then at him, eyes closed and breathing still a little unsteady.

“Our parents come back tomorrow,” I said.

“I know.”

“This is complicated.”

“I know,” he repeated. “Do you want to talk about it now?”

I considered the question longer than I’d expected.

“No,” I said at last.

Adrián nodded. He didn’t say anything else. I lay there staring at the ceiling for a while, listening to the silence of the house, thinking about everything I would need to think about later, when I had enough distance to do it with any clarity.

That distance took longer than I expected to arrive.

“Adrián,” I said, when the room was completely dark already.

“What?”

“The rope. Where did you get it?”

A long silence.

“From the drawer of my desk.”

“And you kept it there because...?”

“Yes,” he said. “For that.”

I couldn’t tell whether I found that terrifying or the exact opposite. Maybe both at once. Maybe that was exactly the problem: that I didn’t find it wrong at all, and that lack of guilt was what I really should have been worried about.

I’ll think about it tomorrow, I told myself. Tomorrow, when they’re here and everything goes back to normal, I’ll think about it.

I closed my eyes.

When my parents came back the next day, the table was set and the coffee was made. My mother asked me if I’d slept well over the break.

I told her yes.

Adrián, from the other end of the kitchen, looked at me for a second over the rim of his cup. He didn’t say anything. No need.
