There was a point in my life when I had no idea how to make myself cum. Eighteen years, to be exact.

It wasn't that I didn't feel horny, god, I am the girl whose pussy juices soak her pants when she's too horny. But girl anatomy is a lot, ok? It's not so easy. Our heads have to be in it in order to ... you get the point.

Mix in my growing attraction to my father that I kept denying to myself, and boom. Virgin me was the pinnacle of sexual frustration.

Things between my brother and me started slowly. I mean, honestly, no sibling set is going to just immediately strip naked for the other. At least not in real life. And while I can admit feeling dirty thoughts about my dad, I hadn't really thought about my brother that way. I mean, sure, he was handsome... arguably, he was hot, but I hadn't ever felt that want for him. Not yet, anyway.

It all started the day I walked in on him with his phone in one hand, cock in the other, stroking intently to some girl he was sexting.

In our house, we split up the chores to avoid having to do the ones we hate. I opted to do all the laundry in exchange for never having to touch a dirty toilet or dishes.

So, when I had walked in on him, it was a complete accident because I was dropping off a bin of his laundry. Of course, I froze, eyes jumping between his cock, the girl fingering her pussy on his screen, and his beet-red face.

"What the fuck?!" he shouted at me.

As he yelled, a drop of precum drooled from the tip of his cock.

My clit ached automatically in response.

I didn't mean to feel that way, but wow, I wish I knew how to masturbate like that, you know?

Sure, I could get horny. My pussy had a habit of getting so wet it would soak through the fabric of my leggings. But for whatever reason, no matter how hard I tried, I just couldn't make myself cum.

So, I stood there, jealous, desperate, and unable to speak. I just stared at him until, finally, I dropped the basket to the floor and bolted, slamming his door shut and moving into my room beside his as my heart thudded in my chest.

Along with my racing heart, my pussy began to leak as it throbbed with need. I felt like a disgusting freak for being so turned on.

You shouldn't be turned on by your brother. You should not be thinking about tasting his big cock.

The thoughts raced and raced as I sat there on my bed. They only got more depraved when I heard his soft groans grow louder. I'd heard my brother cum enough times through our shared wall, and I knew when he was about to cum. I could always hear it—of course I could. He was just on the other side of the wall. Yes, in the past, I had always tried to ignore him, usually opting to put in my earbuds and drown out his ecstasy. But this time, I sat there and listened to him finish, feeling like the worst sister for being so instantly horny because of her brother.

After he finished, I was so jealous and bitter. I spent the remainder of the evening locked in my room trying to forget what happened. It didn't work, of course. Instead, that bitterness festered.

Cue the conversation that happened a few nights later when he ditched me mid-movie binge to go to his room. His excuse was that he was tired.

I snorted, knowing he was definitely not going to go to sleep. "Have fun jerking off."

He froze mid-stride behind the couch - I felt myself flush white-hot as I realized I'd said that out loud.

"What the fuck, Leah?" He gave me an incredulous look.

I didn't say anything. I felt as if I would die of humiliation as I turned my face back to the TV. My heart pounded heavily in my chest as I tried not to hyperventilate.

Why the fuck did I say that? Oh my god, I can't believe I fucking said that!

Of course, he wasn't going to let me get the last word. He couldn't just walk away and leave me to melt into the couch.

He scoffed, "Wow, okay, well maybe you need to rub one out too, Jesus fucking Christ." If hate were a tone, he had it mastered.

God, you’re such a fucking asshole, I thought at him.

He was the one who wanted to hang out and watch these movies! I could've gone out with friends, but he asked me to watch them with him. I was allowed to be annoyed that he was ditching me to go jerk off to some girl he barely knew.

"Yeah, well, if I could, I fucking would. Maybe you having to listen to me cum every day would make you feel as shitty as me." I spat.

Now it was his turn to turn a bright shade of red.

What the fuck... shut up and stop saying things!!

His brows knit together, looking just like Dad as they did. "Did you say if you could?"

Oh no... great now he's just going to torture me forever about never being able to cum. Great. Perfect. I'll just go ki--

"Leah?" He'd moved back to the couch and sat down. A serious expression replaced the annoyance on his face. "Are you saying you've never cum before?"

"Shut up." I spat, feeling the tears pricking at the corner of my eyes.

Dammit, why was I the person who cried when I was mad?

"There's no way... you have to masturbate? You're lying," he continued with a shake of his head.

"Yeah, well, I can't ever finish, ok? Are you fucking happy now?" I sobbed, finally meeting his eyes again.

But he wasn't teasing me. No, his expression was full of brotherly worry. As if whatever was wrong in my world, he'd find a way to correct it—apparently, even this issue.

He quizzed me then. The questions went on and on. Had I tried watching tutorials? Porn? Reading erotica? Fantasizing? Was I rubbing my clit or just putting my fingers inside my pussy?

We were both blushing at that last one. It was one thing to admit I watched porn or read smutty stories trying to get off. But telling him how I tried to get off... that was way, way too personal.

He tried to explain why he was asking that last question: "I just mean girls can't really cum if your clit’s not being worked over, you know-"

"Yeah, I fucking know." I blurted.

He nodded. Rubbed his face with both hands before pushing a sigh out of his lips. "Fuck." He chuffed out a humourless laugh.

"What about a guy touching you? Don't you cum then?" he asked softly, his lips pressed flat.

I couldn't meet his eyes. My brother, the sexually promiscuous golden boy who probably had a body count higher than the odometer in my car ... had a sister who may as well have been the virgin mother herself.

Something on my face gave it away. "You're a virgin?" He breathed this as a whisper as if it was something he never thought possible.

"Have you ever seen me with a guy?" I snapped, glaring at him and wrapping my arms around my knees on the couch.

He laughed out an awkward acknowledgment. No. He hadn't. I'd never been interested in boys during high school. Never had a boyfriend. I hadn't met anyone in college yet who I wanted to try to date, either.

Silence fell.

Awkward. Electrically charged silence fell between us. I think a century passed in that silence. But then...

"Leah..." The way he said my name made my breathing catch. "Do you trust me?"

There it was.

It was the moment in the movie you wait for - the moment everything changes. The decision to set the course for the ending.

Of course, I trusted him. Yeah, he was my annoying big brother, but other than Dad, he was the guy who would burn the world down to keep me safe and happy. It didn't matter that we had different moms and were technically only half-siblings - I was his little sister. And if there was a problem, he would find a solution.

So I said, “Yes.”

And with that, everything would change.

He led me to my room wordlessly.

If I'm honest, I knew what was about to happen. I think I'd decided I wanted it. That I didn't care if it was morally or socially wrong.

So, when he told me to get comfortable on my bed, I listened.

He told me he picked my room over his because I'd be the most comfortable there. He told me I needed to get naked.

I hesitated, terrified, knowing that if I stripped nude, there would be no going back. So, I compromised and took off everything except my bra and underwear.

Why did I listen then if I was so afraid?

Honestly, when I think back, I just remember that burning excitement in the pit of my stomach. It felt like I was lost in space. As if watching myself from far, far away. I wanted him to help me ... I wanted to cum. To finally feel release. I didn't want to turn nineteen and still not know what it felt like to have an orgasm.

In the heat of the moment, I didn't give a fuck about any possible consequences. I just wanted to trust him. I wanted him to help me cum.

He stripped too and sat in his boxers across from me. Our legs brushed, and a bolt of fire burned inside of me. I knew he felt it too because his cock hardened almost instantly in his shorts. He gripped it automatically, holding onto it and staring at me as if finally coming to the same conclusion I was.

This was happening. Neither of us was going to stop it.

He swallowed hard, and my pussy throbbed under my thong as I watched his Adam's apple bob. I wanted to run my tongue along his throat. To feel it bob under my tongue.

Chris instructed me to lie back comfortably against my pillows. To let my legs spread open.

He moved closer, shifting his legs under mine so we were semi-pretzelled together. He rested my legs on his, rubbing them, squeezing them...

God, his hands feel so warm.

"Show me how you touch yourself," he murmured.

I must have looked like I was about to protest because he added, "Do you want to stop?"

I knew he would. He’d stop and leave and probably never bring this up ever again. We didn't need to continue. The ball was in my court. He was saying, I want to do this, do you?

I shook my head. I wanted to keep going.

I moved my thong to the side and showed him how I'd rub the lips of my pussy up and down. Soaking them with my juices before tracing circles around my aching clit. I showed him how I would stick my fingers inside my pussy, trying to massage my G-spot.

He was watching intently as if studying for an exam. Absentmindedly stroking his cock through his shorts as he did. Watching him watch me had my cunt drippier than ever.

"Here," he shifted forward and grabbed the sides of my thong, gesturing for me to lift my ass so he could slip it off.

I followed the wordless instructions. Letting him see my bare and glistening wet pussy lips. I loved how he took in the sight of it. Then his eyes met mine as he reached forward and placed his thumb on my clit.

My body convulsed. He grinned dangerously.

"Good girl," he murmured. "You need to do these kinds of circles - even pressure - use your juice to lube up your fingers so it feels good."

I gasped and grabbed at his biceps. "Holy fuck." I groaned.

His fingers were sending wave after little wave of spasms through my body. I realized as he played with me that I hadn't been doing it right. My pressure was off—and I wasn't being consistent enough. I had never felt that way trying to make myself cum.

He smiled and went to shift back to let me try and continue on my own, but I gripped his arm tighter.

"No ... please..." I begged. His green eyes bore down into mine. "Please... Chris... I need..."

He swallowed hard again, "What do you need?" His voice was thick, with something that made me want to moan.

"I need to cum." I whined softly. "I need you to make me cum."

I swear I saw something primal take over his entire body. It didn't matter that we were family - that we were siblings. We were going to cross that line of no return. There was no going back.

He moved instantaneously. As he got onto his knees, he hooked an arm around my waist. I gasped out a moan as he all but threw me onto my back after he moved us to the end of the bed. I shifted up onto my elbows as he tore off his boxers, finally freeing his cock. It was so hard that it bobbed in the air space between us.

He stood at the end of the bed, looking like he wanted to ruin me.

“Take off your bra,” he demanded. The depth in his voice sent thrills through me.

I discarded my bra and we both drank in each other's bodies. Mine petite and slender, his broad and muscular. I reached for my breasts and squeezed my nipples instinctively. He bit his bottom lip with a wicked grin.

"If you don't tell me to stop right now." He moved forward, grabbing my hips and dragging me to the edge of the bed in front of his pelvis. "I will fuck you so hard you won't be able to walk to your lectures tomorrow."

I pinched my nipples harder and groaned. "Don't you dare fucking stop," I gasped.

A second later, he slammed his cock inside me.

My brain shattered.

I can't tell you if it was him or me who groaned like an animal. I can't remember anything but the ecstasy of feeling his cock stretch the muscles in my vagina and the thumb he had immediately used to put pressure on my throbbing clit.

It didn't hurt. Surprisingly. I was expecting pain, but it didn't come. I was too wet for there to be any pain.

There was just him, repeatedly thrusting into me. Slowly pulling out and then slamming back into me. Our bodies slapped together sharply, loudly. Too loudly. If our dad came home early from work, he would definitely hear the two of us getting lost in each other.

Chris grabbed one of my hands and forced my fingers on my own clit, ordering me to rub myself. Then he grabbed my legs and pushed them back so my knees were at my ears before stepping onto the bed. He lined up his cock as he half-squatted.

There was no more slow thrusting; he started fucking me hard. He buried his cock into me, slamming so hard his balls squished against me. I could barely keep up with rubbing my clit, the angle he was plowing me was so damn intense.

He moved, pressing against the underside of my knees, using my legs to hold himself at the perfect angle to plow my pussy. I couldn't help the groaning screams coming out of my throat.

"Oh God," I cried.

"Yeah?" he groaned a laugh. "You fucking like that, don't you?"

There was a growing tightening deep in my stomach. It tugged harder and harder as he fucked me harder and harder.

"Ye-yes, Oh my fucking god," My voice vibrated at a higher pitch than I thought possible.

He had a cocky smirk in his eyes, "My baby sister takes it like a good little slut," he praised.

"Mhm," I moaned.

"Fuck," he growled, hands tightening on my legs. "You so fucking tight."

"Yo-you feel huge," I whimpered.

He really did. It felt like he was ripping me in half, but in the best possible way.

Then it happened. A sharp urge twisted inside me, and I yelped. He took that as a good thing and chuckled as he panted above me.

"No, stop, I'm going to pee," I screamed, wiggling underneath him.

"No,” he growled, as he slowed to a stop. "That means you're going to cum, Leah."

I panted as I came down from the ledge. “It felt like I was going to pee, like a warm pressure.”

“Leah, you were about to fucking cum - you need to ride out that feeling.”

Chris pulled out of me with a pop and told me to move back farther on the bed. He moved on top of me, pressing the full weight of his body against mine. My sharp nipples grazed his chest and sent a shiver down my spine.

“What do you want, Lee?” he murmured, kissing my neck. "Do you want to stop?"

I ran my fingers through his hair, gripping it gently to bring his face just inches from mine.

"No..." I admitted.

His mouth found mine, enveloping mine with his. Our tongues danced—god, the taste of him was incredible. It felt like he was trying to suck my soul out of my mouth. And I was letting him.

Chris pulled away, and his hands pressed against my face, and he held my eyes with his. Our eyes were twins; pairs of warm, melted chocolate.

"Tell me what you want, Leah."

“I want you to fuck me until I cum.” I whispered.

His mouth met mine again, and I moaned into his mouth as he claimed every part of my body. Slowly, but deeply thrusting into me. Each slap of his pelvis against mine made me gasp against his mouth.

He pushed back onto his knees and grabbed my hips, angling myself so he could slide into me with ease. One hand held me in place by my hip, while the other moved to my clit. He started fucking me harder, never lifting his thumb off my clit as he did. The same pressure began to build up in me, and I covered my mouth to...
