I still feel the ground shaking under me when I think about that night.

The big quake hit at dusk, rattling our old family house until pictures fell and the lights went out. My brother Jake and I were the only ones home, both of us twenty-three and stuck together while our parents were out of town. After the initial panic we checked the place for damage, then settled in the living room with flashlights and a bottle of whiskey to calm our nerves. The aftershocks kept coming, each one a low rumble that made the floor tremble and our hearts race. One hit hard around midnight and threw us against each other on the couch. Jake’s arm went around me to steady us both, but he didn’t let go. His hand stayed on my waist, fingers pressing through my thin tank top, and suddenly the air changed.
“Fuck, that one was close,” he muttered, voice low and rough. I could smell the whiskey on his breath and feel the heat of his body. My nipples tightened against the fabric, and I knew he noticed because his eyes dropped straight to my chest. Instead of pulling away I leaned in, pressing my tits against him. “Don’t stop,” I whispered. That was all it took. His mouth crashed onto mine, tongue pushing deep while his hands yanked my top up and off. He squeezed my bare breasts hard, thumbs rubbing my stiff nipples until I moaned into his kiss.
We tore at each other’s clothes right there on the couch. Jake’s cock sprang out thick and already leaking when I shoved his jeans down. I wrapped my fingers around it, stroking the hot length while he kicked his pants away. “Suck it,” he growled. I dropped to my knees between his legs and took him into my mouth, lips stretching around the head. I bobbed fast, getting him sloppy wet, saliva dripping down his shaft onto his balls. He grabbed my hair and fucked my throat, hips jerking every time another aftershock rolled through the house and made everything vibrate.
“Get up here and ride me,” he ordered. I climbed onto his lap, straddling his thighs. My pussy was dripping, and I sank down on his cock in one smooth motion, taking every inch until my ass met his lap. We both groaned loud. I started bouncing, tits jiggling in his face while he sucked on my nipples and slapped my ass. The couch creaked with every thrust. Each aftershock made my cunt clench tighter around him, the shaking adding this wild extra friction that had me soaking his balls.
Jake flipped me onto my back without pulling out. He hooked my legs over his shoulders and pounded me deep, the head of his cock hitting that spot inside that made me see stars. “You like your brother’s dick, don’t you?” he snarled, fucking me harder. I nodded, whimpering yes, yes, fuck me. He reached down and rubbed my clit in tight circles until I came hard, pussy pulsing and squirting around him. The aftershock that hit right then felt like it was coming from inside my body.
He pulled out, flipped me onto my stomach, and hauled my hips up. He slammed back in from behind, gripping my ass cheeks and spreading them so he could watch his cock disappear into my wet hole. “Gonna fill you up,” he panted. I pushed back against him, begging for it. When he came he buried himself to the hilt, flooding my cunt with thick ropes of cum that leaked out around his shaft. We stayed locked together through one last trembling aftershock, both of us breathing like we’d run miles.
Afterward we didn’t talk much. We just stayed tangled on the ruined couch, his cum still dripping from me, the house finally still. The forbidden heat between us felt bigger than the quake itself. We knew it wouldn’t be the last time.
