Step Secretary

As he wound his fingers through my hair, I moaned for him, turning to press against his chest. “Big brother…”

Then I stopped, my cheeks turning even redder as I realized what I’d said. “Um…”

I was worried he would stop, too. But Jacob only cupped my face in his hands, looking into my eyes as he traced my lower lip with his thumb.

“Say it again,” he whispered. “Call me your big brother.”

I felt a flood of desire between my legs and squirmed, whimpering as my robe fell down around my waist. Was he really turned on by me calling him that?

The truth was that I was, too. It was dirty and wrong, and something our parents never would have abided. That just made me want to do it all the more. For once, I wanted to be the bad girl they made me out to be.

“Kiss me, big brother,” I whispered, and Jacob obliged, kissing me again as he pulled me up into his lap.

I straddled his hips, wrapped my arms around his neck, and slipped my tongue between his lips, gliding it along his own. I shivered at the realization that I was tasting my stepbrother, but it was so good that I couldn’t stop. I could feel his body pressing hard against mine, could feel the heat between his legs grow to match my own, and as I grinded against him, I heard him moan my name.

“Amber…”

I sank to my knees, opened up his pants, and dragged them down around his thighs until my stepbrother’s cock sprung out. It was hard and thick, bigger than anything I’d seen on a man before. He wasn’t a boy anymore… My stepbrother was a man.

I didn’t even give myself time to stop and think about what I was doing. I looked up into Jacob’s eyes and leaned forward, pressing my breasts against his thighs as I took his dick into my mouth.

He moaned again, and the sound filled me with lust, spurring me on to take more and more of his length between my lips. I laved my tongue along his tip, swirling and twirling, coaxing warm beads of precum to leak out. I closed my eyes. He tasted absolutely sinful.

I understood now why Jacob looked at me the way he did, why he seemed so sad when he said he wished we’d have met some other way. He wanted me, not as a sister, but as a lover. But why couldn’t I be both?

Jacob gripped my hair, pulling it away from my face as he began to thrust into my mouth, his gaze fixated on his long shaft slipping in and out of my full, wet lips. I relished each motion of his hips, lapping at him hungrily, trying to draw him deeper and deeper down my throat.

Soon I felt him throbbing, his shaft swelling inside my mouth, and with a soft grunt he pulled away, only a thin thread of my saliva connecting us.

“Come here,” he said, and I obeyed, returning to my big brother’s lap where I pushed aside my panties to sit down hard and fast on his aching cock.

I threw my head back in bliss as he penetrated me, gasping and raking my nails along his biceps. He cradled me against him, pushing his girth past my tight hole and into the depths of my needy cunt. I knew he was in for a surprise. I’d had a boyfriend back at home, and we’d fooled around, but I’d never let anyone do this… I kept telling myself I was saving my virginity for the right man. I never thought it would be my stepbrother…

“Amber… Oh God…” he whispered as his cock pressed up against my hymen. There was no denying it now. He knew I was giving him my innocence, and it brought a fire out in his eyes unlike anything I had ever seen.

“Take me, big brother. Claim me…”

He pulled my downward, his huge cock tearing through the thin barrier and stretching me beyond anything I could have imagined. When I finally made contact with his balls, he grabbed my hips tighter still, urging me to move, to take him again and again into my tight channel.

“Be as loud as you want to, baby sister,” he told me, watching my tits bounce. “Mom and Dad can’t hear us now.”

I moaned for him, realizing he was right—there was no reason to hold back my pleasure. I began to bounce, working myself up and down his meaty cock, letting it stretch me wide as I fucked my stepbrother for the first, but not the last time. Hints of pain mingled with incredible pleasure. I knew now that I could never give this up, that we were meant to be together in more ways than one. We just fit so perfectly, my tightness around his thick shaft. I’d never known ecstasy or happiness like I did with him.

Some of my fondest memories were of my stepbrother, of his smile, his tenderness, his charm. And now he was below me, panting and squirming, caressing my tight, firm body as I used it to bring him the same warmth and comfort he’d always brought me.

“Fuck, big brother,” I squealed, reaching down to rub the swollen bud between my thighs. “I can’t take it anymore. I’ve gotta cum…”

Jacob growled, holding me steady as he fucked me from below, pistoning in and out of my cunt as I rubbed and stroked it. He got so much deeper inside of me than I could have imagined, and in only a few moments, I was cumming around him, bursting with the rapture he had brought me.

I wailed his name, my walls clenching hard and rhythmically around his cock, milking him for that sweet cum I’d had only a taste of on my knees before. Jacob grunted in reply, bucking his hips with reckless abandon, his strangled sounds becoming even more strained as his dick filled with the seed I knew would soon come pouring into me. In an instant, I realized that I hadn’t given him a chance to wear a condom. He was going to cum inside me, and the thought of it drove me absolutely wild.

“Yes, big brother!” I cried for him. “Cum in me. Cum in your little sister!”

“Amber,” he snarled, burying his face in my neck. “Oh—fuck!”

And then he too was bursting, spilling inside of me, his warm, wet lust spurting deep inside my cunt. I bounced a little for him, begging him for more, wanting to feel my brother fill me up to the very brim and come spilling out over my thighs. I wanted to drip with him.

“Please,” I begged him, “don’t stop…”

But he couldn’t keep cumming in me forever, and after a few moments of primal bliss, he finally settled, holding me against his body as his chest heaved. I buried my face in his hair, shivering as I thought of what we’d just done and where we might go from here.

This was all happening so fast. I’d only just moved out of our parents’ home and into his after years of very little contact between us. Our relationship had been strange already, and now we’d only added another layer of complexity to it with our apparently mutual lust.

What would Jacob say when he recovered? Would he hate me? Would he throw me out?

I stiffened, worry flooding my veins. But then my stepbrother looked up at me, a heavy sigh passing his lips as he slowly, mischievously grinned.

“Wow,” he said. “Just… wow.”

Then he kissed me on my lips. It was just as passionate and breathtaking as our first had been. I melted into him, purring as he laid me on the couch and drew me against his half-naked body, allowing me to nestle into the hollow of his throat as he added:

“I think I’m going to like having you live with me, sis.”

I laughed, hiding my face in his chest as he lovingly stroked my hair. “I think I’m going to like it, too,” I told him. “As long as you keep doing this, that is.”

Jacob tilted my chin up, forcing me to look up at him as he smirked. “I don’t think I can stop, even if I wanted to,” he told me, pressing his lips to mine once again.

I smiled as I surrendered to his kiss, knowing that once and for all, I had finally found the place I could call home.

Forever…
