It’s wrong. I know it is.

But every time I try to stop, he shows up at my door with that look in his eyes, and all my resistance melts away.

Tonight was no different.

I was lying in bed, restless and aching, when my bedroom door opened quietly. It was him — my step-brother, Alex. He didn’t say a word. He just closed the door behind him, locked it, and walked over to my bed like he owned it.

Like he owned me.

“You’ve been thinking about me again, haven’t you?” he murmured, his voice low and rough.

I didn’t answer. I didn’t need to. He could already see it in the way my breathing changed.

He pulled the covers off me slowly, his eyes roaming over my body. I was only wearing a thin tank top and panties. He hooked his fingers into the waistband and slid them down my legs without asking.

Then he spread my thighs wide.

He knew exactly what I needed.

No teasing. No slow build-up tonight. He buried his face between my legs and devoured me like a man starved. His tongue was relentless — licking, sucking, fucking me deep. I grabbed his hair, hips bucking against his mouth as pleasure shot through me.

“Fuck… Alex…” I moaned, trying to stay quiet.

He didn’t stop. He added two fingers, curling them perfectly against that spot he knew so well. My legs started shaking. He sucked my clit harder, and I came hard, biting my pillow to muffle my cries.

But he wasn’t done.

He climbed on top of me, pushed my legs back, and thrust into me in one smooth, deep stroke. I gasped at how full I felt. He fucked me hard and steady, eyes locked on mine the whole time.

“You’re mine,” he growled. “Say it.”

“I’m yours,” I whimpered, lost in the pleasure.

He pounded into me faster, deeper. The bed creaked under us. I came again, clenching around him so tightly that he groaned and filled me with his cum, collapsing on top of me.

We lay there tangled together, breathing hard, his cock still inside me.

He kissed my forehead softly and whispered, “Good girl.”

I know this is wrong. I know we shouldn’t keep doing this.

But when he touches me like that… when he takes control the way only he can…

I don’t want him to stop.
