Caught my little brother

A few days ago I caught my little brother jerking off to my private pictures and honestly my whole world flipped upside down. I was supposed to be out with my friends that afternoon but I felt kinda sick so I came home early. The house was super quiet, mom and dad were still at work, so I just wanted to go to my room and lay down. But when I walked past his door it was cracked open just enough for me to see inside and what I saw made me freeze right there in the hallway.

There he was, my little brother, sitting on the edge of his bed with his shorts all the way down to his ankles. His phone was in one hand and with the other he was stroking his cock really slow, like he was savoring it. I recognized the pictures on his screen right away — they were mine. The ones from last summer at the beach where I was wearing that tiny red bikini that barely covered anything. Some of them were the private ones I only sent to my ex, the ones where I was posing all sexy with my tits almost spilling out and my ass looking huge. He had them zoomed in and everything. His breathing was all heavy and I even heard him whisper my name like “Fuck… sis… you’re so fucking hot” while his hand moved up and down faster.

My heart started pounding so loud I thought he was gonna hear it through the door. I should’ve been mad, right? I should’ve burst in and screamed at him or told mom and dad what a perv he was. But instead I just stood there staring, my face getting hotter and hotter. Something weird happened in my body. My nipples got hard under my shirt and I felt this warm tingle between my legs. Seeing him like that, so desperate and horny for me… it turned me on. I got wet. Like, really wet. I squeezed my thighs together without thinking and kept watching him pump his hand, his cock all shiny from the lotion he was using.

I don’t know how long I stood there but eventually I couldn’t take it anymore. I pushed the door open and stepped inside. He jumped so hard he almost fell off the bed. His phone went flying, he tried to yank his shorts up but it was way too late. His cock was still rock hard, sticking straight up, and his face went bright red. He looked like he wanted the ground to swallow him.

“Sis! Oh shit… I… I can explain—” he stuttered, voice cracking like he was about to cry.

I closed the door behind me and locked it. My legs were shaking but I tried to sound calm. “So this is what you do when nobody’s home? You jerk off to your big sister’s pictures?”

He couldn’t even look at me. Just stared at the floor, hands trying to cover his lap. “Please don’t tell mom and dad… I’m so sorry, I know it’s messed up. I just… I can’t help it. You’re really pretty and those pictures… they drive me crazy.”

I walked closer until I was standing right in front of him. My panties were already soaked and I could feel my clit throbbing. The words came out before I could stop them. “If you like jerking off to me so much, then do it right now. No pictures. Let me watch you do it live while you look at the real thing.”

He stared at me with his mouth open. “What? You’re… you’re serious?”

I didn’t answer with words. I just grabbed the bottom of my t-shirt and pulled it over my head, letting my long hair fall down my back. Then I unhooked my bra and let my tits spill out. They’re pretty big and my nipples were already stiff. His eyes went straight to them and he swallowed hard. I pushed my shorts and panties down together and stepped out so I was completely naked in front of my own little brother. My pussy was shaved smooth and I knew he could see how wet I was because my thighs felt slippery.

I sat on the edge of his bed, only a foot away, and spread my legs just a little. “Go on,” I said, my voice shaky. “Stroke it for me. Show me exactly how you do it when you think about me.”

He hesitated for a couple seconds, then his hand wrapped around his cock again. It was thicker than I thought and the head was all swollen. He started stroking, slow at first, eyes locked on my tits then dropping down to my pussy. His breathing got faster right away. I watched him and bit my lip, my hand sliding between my own legs without thinking. I rubbed my clit in slow circles while he pumped faster.

“Faster,” I told him. “Yeah, just like that. You’ve been doing this a lot, haven’t you? Thinking about fucking your big sister?”

He nodded and groaned. “Every single day… I can’t stop. Your body is perfect… those tits… your ass in those tight shorts you wear around the house…”

Hearing him say that made me even wetter. I spread my legs wider and slipped a finger inside myself so he could see. He stroked faster, precum leaking from the tip. I reached over and pushed his hand away, wrapping my fingers around his cock myself. It was so hot and hard. I stroked him nice and slow, twisting at the head the way I thought guys liked. He moaned loud and his hips bucked.

But then I stopped. I pulled my hand back even though I was dying to keep going. My pussy was aching so bad but something in me said not yet. I stood up, still naked, and looked down at him. “If you want more… don’t do it alone next time. Come find me. But not today.”

I grabbed my clothes and left his room fast, my heart racing. I went straight to my room, locked the door, and fingered myself until I came so hard I had to bite my pillow so I wouldn’t scream. I came thinking about his cock in my hand.

The next few days were pure torture. Everything felt different. At breakfast he couldn’t look me in the eyes and I kept catching him staring at my tits when he thought I wasn’t looking. I started wearing shorter shorts and tighter tops around the house on purpose, no bra sometimes, just to see what he would do. Every time I walked past him in the hallway I could feel the tension, like the air was electric. One night I was in the kitchen getting water in just a tank top and panties and I felt him behind me. He was hard — I could see the bulge in his sweatpants. We didn’t say anything but I bent over a little more than I needed to while reaching for a glass. I was so wet I had to go back to my room and masturbate again.

We started texting a little. Stupid stuff at first, like “what time is mom coming home” but then it got flirty. He sent me a meme and I replied with a selfie in my bikini from the same photos he was jerking to. He just replied “fuck sis” with the fire emoji. I laughed but my pussy clenched. I was touching myself every night thinking about him, imagining what it would feel like to have him inside me. I felt guilty but I couldn’t stop. He was my little brother but he made me feel more wanted than any guy I’d ever been with.

Last night the tension finally snapped. Mom and dad were out for dinner and a movie so we had the house to ourselves for hours. I was in my room scrolling on my phone when I heard a soft knock. I knew it was him. My heart started racing again. I opened the door and there he was, looking nervous but determined.

“Sis… about the other day…” he started.

I didn’t let him finish. I grabbed his shirt and pulled him inside, closing and locking the door behind him. “I’ve been thinking about it every day since,” I whispered. “I want to see you jerk again… but this time I want more.”

I didn’t wait. I pulled my tank top off and my shorts and panties followed. I was naked in seconds. He stared at me like I was the only thing in the world. I pushed him onto my bed and climbed on top, straddling his lap. “Take your clothes off,” I told him. He stripped so fast it was almost funny.

His cock was already rock hard, even bigger than I remembered. I wrapped my hand around it and started stroking him again, slow and tight, just like before. He groaned and grabbed my tits, squeezing them while I pumped him. Precum was leaking everywhere. I leaned down and took him in my mouth. This time I didn’t stop at the head. I sucked him deep, bobbing my head, using my tongue all over the underside. He tasted salty and warm and I loved it. I gagged a little when he hit the back of my throat but I kept going, spit running down his shaft and over my chin. He had his hand in my hair, moaning my name over and over.

After a few minutes I was too horny to wait. My pussy was dripping onto his thigh. I climbed higher, straddled him properly and rubbed his cock up and down my soaked slit. “You want to fuck your big sister?” I asked, looking right into his eyes.

“Yes… please…” he begged.

I sank down slowly. Inch by inch his thick cock stretched me open until he was buried all the way inside me. We both moaned loud. I sat there for a second, feeling so full, his balls pressed against my ass. Then I started riding him. Up and down, rolling my hips, grinding my clit against him every time I came down. My tits were bouncing right in his face and he sucked on my nipples while I rode faster. The sound of my wet pussy slapping against him was so loud in my quiet room.

“Fuck me harder,” I gasped. “Your cock feels so good inside me…”

He grabbed my hips and started thrusting up to meet me. We were going fast now, both of us sweating and moaning. I could feel my orgasm building deep inside. My thighs started shaking.

“I’m gonna cum… oh god I’m cumming on your cock!” I cried out.

It hit me like a wave. My pussy squeezed him so tight and pleasure exploded through my whole body. I kept riding through it, moaning his name. That pushed him over the edge too. He grabbed my ass hard, pulled me down onto him and started cumming. I felt every hot spurt — thick ropes of his cum shooting deep inside my pussy, filling me up completely. He groaned loud and his whole body tensed under me as he emptied himself.

We stayed like that for a long time, me still sitting on his cock, both of us breathing hard and sweaty. His cum was leaking out around him and running down my thighs. I leaned down and kissed him softly on the lips, then on the forehead.

When I finally lifted off, a big glob of his cum dripped out of me onto his stomach. I looked at him and smiled even though I was still catching my breath.

“Next time you feel like jerking off to me… just come straight to my room. No more hiding.”

I don’t know what’s gonna happen now. It’s been a few days since I first caught him and last night changed everything. I know it’s wrong — he’s my little brother — but I can’t stop thinking about how full I felt with him inside me. My pussy is still sore and I can still feel his cum leaking out while I write this. I feel guilty but mostly I feel horny. I already want to do it again. Maybe even tonight when mom and dad go to sleep. I don’t know where this is going but right now I don’t care. It felt too good to stop.
