I knew I shouldn’t keep porn on my laptop, but one afternoon after college classes, I walked into my room and caught my younger brother Jake—freshly 18 and home from his first semester—watching a hardcore video of a hot blonde getting railed. He was already rock-hard, tenting his shorts like crazy. He heard my footsteps, spun around, and froze when he saw me leaning against the doorframe.
“So… you into that?” I asked, smirking, eyes dropping to the obvious bulge.
He blushed hard but didn’t back down. “Yeah… and you do too, apparently.”
I stepped closer, dropping my gaze to his crotch again. “Looks like it.”
He swallowed. “Who’s the girl in the video?”
I glanced at the screen—her riding reverse, moaning like crazy. “Just some chick getting pounded. Ever wonder what it feels like?”
Jake’s eyes widened. “You… you ever…?”
“Not yet,” I said softly, kneeling in front of him. “But I’ve thought about it. A lot.”
Before he could overthink, I tugged his shorts down. His cock sprang free—thick, veiny, perfect. I wrapped my lips around the head, tasting him for the first time. He groaned, hand gently resting on my head as I took him deeper, sucking slow and wet, tongue swirling around the shaft. I looked up at him, eyes locked, moaning around his length like the filthy big sister I suddenly wanted to be.
He didn’t last long. I felt him throb, then explode—hot spurts hitting the back of my throat. I swallowed every drop, milking him until he was spent, then licked him clean with a wicked smile.
“Fuck… that was insane,” he panted, still dazed.
I stood, wiping my lips. “You liked your big sister sucking you off?”
He nodded, breathing hard. “Can we… do more?”
I grinned. “Wait here.”
I slipped into Mom’s room, grabbed her sexiest black lace lingerie set—thong, push-up bra that made my tits look even bigger—and a short black skirt. Quick makeup: red lips, mascara, a little blush. I looked in the mirror—damn, I looked like a pornstar version of myself. I let my hair down loose and walked back in.
Jake’s jaw dropped. “Holy shit, Emily… you’re fucking gorgeous.”
He pulled me close, kissing me hungrily, hands roaming my ass, sliding under the skirt to squeeze. His fingers found my thong soaked already. He kissed down my neck, nibbling my ear, whispering, “I want to fuck you so bad, sis.”
I turned him around, bent him over the desk, yanked his shorts down again. I spread his cheeks, teased his hole with my tongue, then slid two wet fingers inside. He moaned loud, pushing back.
“You’ve played with toys before, huh?” I teased.
“Yeah… but never the real thing,” he admitted, voice shaking with need.
I lubed my fingers more, worked three in, stretching him slow. Then I stood behind him, rubbed my dripping pussy against his ass, teasing.
“Beg for your big sister’s cock—wait, no… beg for your big sister to fuck you,” I whispered.
“Please, Emily… fuck me. I need it.”
I slid two fingers back in while stroking his cock from behind, edging him. Then I couldn’t wait anymore. I pushed him onto the bed on all fours, climbed behind, and guided my strap-on (I’d grabbed Mom’s favorite toy from her drawer) right to his hole.
I pushed in slow—inch by inch—until I was buried deep. He gasped, gripping the sheets. “Oh fuck… yes, sis… fuck your little brother.”
I started thrusting—slow at first, then harder, slapping his ass with every stroke. “You like your big sister owning your tight hole?”
“Yes! Fuck me harder!”
I grabbed his hips, pounded deep, my tits bouncing in the bra. He jerked himself furiously, moaning like a slut. I felt him clench around the toy, then he exploded—cum shooting across the sheets. I kept fucking him through it, riding the high until I came too, grinding against him, clit throbbing.
We collapsed together, sweaty, panting.
“Best secret ever,” he whispered.
I kissed his neck. “Round two after dinner?”
He grinned. “Fuck yes, sis.”
