Stepbrother's Dangerous Obsession

I opened my eyes. My arousal shot straight through the roof. God, yes.

He was standing over the couch, his emerald stare blazing as he stroked his naked dick. I couldn't help but stare as it lay in his palm, thick, smooth, and fully erect, a drop of pre-cum beading at its pulsing head. Liam cursed. A torn look ravaged his shocked eyes, and I could tell he was trying to snap out of it. His biceps twitched as he tried to stop stroking, but it was in vain. He was a hundred eighty-five pounds of pure muscle, but he couldn't stop jerking off in front of me. It was such an unbelievable turn-on. He couldn't tell if I was awake or dreaming or if it was all a prank, but it didn't matter at this point because I had gotten him too hard not to get off. He needed desperately to cum.

And so did I.

"Liam, touch me," I begged softly, one hand reaching for him, the other still rubbing my clit. Liam's eyes were wild. He forced them away from me.

"Fuck." He winced as he stopped stroking. I could see him desperately fighting through his lustful haze. "What the fuck am I, holy fuck, I'm so sorry."

"Don't be. Liam, don't stop. Please. Let me help you come."

"Sash, I have no idea what's going – "

"Liam." I shut him up when I sat up on the couch, wrapping my fingers around his thick shaft. He stared down at me, every inch of his inked and muscled body in total awe, rendered useless by my hands.

"I'm here. I'm awake. I know what I want, and what I want is to make you come. Can I?"

His frantic eyes studied me, unable to process the moment. His smooth, gorgeous lips opened and closed several times before he found his words.

"Baby," he frowned so deeply, so handsomely. "This isn't supposed to be happening. I don't know what just came over me right now, but we can't."

"Answer me, Liam. Don't you want me to suck on your cock?" I gave his smooth tip a slow, full lick that made his head fall instantly back. A brutal groan dispelled from his lungs toward the ceiling.

"Fuck, do that one more time."

I did. Even slower this time, followed by a little suck.

"Fuck!" He growled, pulling my hair. "We can't do this, baby. We can't."

"Yes we can. You want this, I want this, and I want you to come down my throat, Liam. I want to swallow every drop."

"Baby," his protest cut off as I began sucking his flared tip like a lollipop, reveling in its thick, silky smoothness. His body caged around me.

"If you don't stop – "

"I don't want to," I whispered before dropping my mouth as far down as I could on his shaft. My cheeks hollowed as I sucked, giving my all with every tight, wet pull. Liam finally surrendered.

"Fuck, Sash."

He growled and fisted my hair with both hands, moving my head back and forth over his rock-hard length. He pumped his hips, thrusting into my mouth and forcing me to take as much of his steel cock as I could manage.

"Christ, baby, you're so fucking good," he rasped, driving himself in and out of me. My lips swelled numb within seconds. They stretched around him, hot, tingling, and happy to accommodate his girth.

"God fucking damn it, this is wrong," Liam hissed, stroking my hair and fucking between my lips before holding my full mouth suddenly still for a moment.

"Look at me, Sasha," he demanded, his head pulsing at the back of my throat as I looked up at him. I savored the sight of my stepbrother glaring down at me, his dick in my mouth and his hands tangled in my hair. I had waited ages for this moment, fantasized endlessly about it. I had been told by friends and frenemies alike that it would never happen. Not only was I Liam's stepsister, I wasn't the type he went for. I wasn't the type of dirty, sexy, bad girl that he needed. And they were right. I wasn't.

But I was for him.

"Listen to me." Liam rocked lightly, slowly into my mouth as he growled at me, a predator sedating his prey. He shook his head as he took me in, my mouth still sucking dutifully on his cock. "You were the only thing that was off-limits, Sash. It took everything in me to be just a good brother to you," he seethed, tightening his grip on my thick waves, his words sending the hottest thrill through my body. It rippled over every inch of my skin.

But what he said next surprised me. "You're gonna wish you never did this to me, babe," Liam whispered fiercely, dropping a hand to my neck and wrapping his fingers around my throat. "Now swallow when I cum in your mouth."

With that, his seed speared endlessly onto my tongue, seeping like a hot waterfall down my throat. I was barely touching myself anymore, but I shook to orgasm from merely watching Liam's gorgeous face contort. He gnawed his teeth as he flooded my mouth with his bitter pleasure, his grip tightening on my hair, on my throat. In that moment, it felt like I was his.

In every way, Liam owned me. Yet at the same time, it felt as if he were freeing me, giving me the escape I had wanted from the sweet little princess I was supposed to be for him. That poor, damaged little thing. I wanted her gone. I deserved pleasure too, and now, I was finally getting it.

"Good girl." Liam's eyes smoldered into me as I flashed him a peek of my clean tongue before running its tip along my parted lips, cleaning up the last few drops of his seed that had overflowed from my mouth. He watched every second of my display before shoving me back down on the couch, still possessed by rage and lust.

"Now you're going to come again for me, Sash. And this time, you're going to say my name."

He climbed on top of me and slid two fingers into my pussy, pumping with instant strength and speed that brought me quickly back to the edge. The second he sucked the tip of my breast into his mouth, I was unraveling. But it only got better.

With the heel of his palm pressed against my clit, a storm of sensation rocked my whole body. It was merciless, and suddenly I was screaming his name.

"Again," he growled.

"Liam! Oh God..."

Liam stared into my eyes as he watched me come and come down, fire flaming behind those pools of dark green. Withdrawing from my pussy, he slid his finger into my mouth. I was weak but sucked it dry, feeling the last bit of his cum drip onto my belly as my exhausted, deliriously pleasured body failed to stay awake.

The last thing I remembered before drifting into true slumber was Liam. He carried me into my room and tucked me into my bed.

I had the capacity to wonder what the hell he must be thinking before finally falling asleep.
