I hoped we would pretend last night never happened… But I guess my big bro cannot get enough of my tight teen pussy.
Mom stood in the doorway, her face pale as a ghost, eyes locked on us—me impaled on my brother’s massive cock, his cum flooding my pussy right in front of her. I could feel it gushing out, hot and sticky, mixing with my own juices as it dripped down my thighs. My body still shook from the orgasm, walls clenching around his throbbing shaft, but horror hit me like ice water. What the fuck? Our mom, witnessing her son breeding his little sister. I froze, heart pounding, Sam’s dick still buried deep, twitching inside me.
I didn’t know what to do—scream? Cry? But my mind raced, and the sleepwalking lie popped out. ‘Mom, he… he’s sleepwalking,’ I stammered, voice shaky, pushing at Sam’s chest like I could make it true. ‘He thinks I’m Amber. I couldn’t wake him up. Please, just… go.’ My cheeks burned, pussy still stuffed full, his cum leaking as I shifted.
Sam blinked, playing it perfect—his eyes glazing over like he was lost in a dream. He stared at me, confused, murmuring softly, ‘Amber, you’re so beautiful… thank you.’ Then he pulled out with a wet squelch, my sore pussy gaping, cum pouring onto the sheets. He staggered off the bed, dick swinging heavy and slick between his legs, not even glancing at Mom as he shuffled past her out the door, butt naked.
Mom’s mouth hung open, but she didn’t say a word—just turned and left, closing the door quietly like she’d seen a nightmare she wanted to forget. I curled up, sobbing into my pillow, the ache between my legs a constant reminder of my brother’s huge cock stretching me, the taboo cum sloshing inside. How could she ignore that? But she did, and the house went silent.
The next morning, everything felt wrong. Amber showed up to hang out, all bubbly and clueless, plopping on the couch with Mom watching some show. Sam and I avoided eye contact at breakfast, my pussy still tender from last night, a dull throb every time I sat. I excused myself to the bathroom for skincare, locking the door out of habit, splashing water on my face, trying to scrub away the guilt and the weird heat lingering low in my belly.
The lock clicked—wait, no. Sam pushed in, tall and muscular, filling the small space. He locked it behind him, eyes dark. ‘Amber’s watching TV downstairs. Told her I’d be right back.’ His voice was low, rough, like he hadn’t slept.
‘Sam, what—’ I started, but he stepped closer, towering over my petite frame.
‘I’m so sorry about last night, sis. I can’t believe it happened. You’re my baby sister—15, innocent. I was out of my mind.’ He pulled me into a hug, his strong arms crushing me against his chest, head dipping to my neck.
I hugged back, forgiving because it was him, my big bro. ‘It’s not your fault. Sleepwalking… it’s okay.’ But his hands lingered, sliding down my back, gripping my ass through my thin dress. He inhaled deep, lips brushing my skin. ‘You smell so good,’ he murmured, kissing my neck softly at first.
‘Sam, stop—we can’t.’ I tried pulling away, heart racing, but something snapped in him. His grip turned iron, yanking my dress up and over my head in one rough pull, exposing my small tits and the tiny panties underneath. ‘No!’ I gasped, but he ripped the fabric aside, shreds falling to the tile.
He lifted me like I weighed nothing, slamming my back against the cool wall, my legs wrapping instinctively around his waist. His pants were already down—his huge cock sprang free, thick and veiny, slapping against my bare pussy. ‘Fuck, sis, I haven’t stopped thinking about your tight little pussy all night,’ he groaned, thrusting up hard. The head split my lips, burying deep in one brutal shove, stretching my sore walls again.
‘Ah! Sam, no—our parents are next door, Amber’s right downstairs!’ I sobbed, nails digging into his shoulders, the pain mixing with that forbidden spark. But he just pounded harder, balls slapping my ass, grunting like an animal. ‘That’s what makes it so fucking hot,’ he rasped, pinning my hips, railing me against the wall. My petite body jolted with each slam, tits bouncing, pussy clenching despite the tears.
‘I’m only 15, bro—too young for your big dick!’ I whimpered, but he growled, dropping me suddenly to the floor. He grabbed my ankles, folding my legs up over my head, my ass lifted off the tile, pussy exposed and dripping. He plunged back in, deeper now, the angle battering my cervix. ‘That’s right, my baby sis—15 and taking your brother’s cock like a slut. Your tight underage pussy was made for me. So wet, squeezing me so good. Fuck, I love how you fight it but cream all over my dick.’
His words burned, filthy and sweet, making my body betray me—juices slicking his shaft as he hammered down, the wet smacks echoing off the tiles. I bit my lip to stifle moans, scared we’d get caught, but the risk twisted hotter in my gut.
Then—knock knock. ‘Sam? You okay in there?’ Amber’s voice, right outside the door.
We both froze, his cock buried to the hilt, my pussy fluttering around him. His eyes dropped to where we joined, watching my lips grip his thickness. He slapped a hand over my mouth, hard, muffling my gasp. ‘Yeah, babe—just finishing up. Be right out,’ he called, voice steady, but he started fucking me slow, grinding deep.
I whimpered into his palm, eyes wide, but he just smirked, thrusting lazily. ‘Shh, sis—the fact she’s right outside, listening? So fucking hot. My girlfriend waiting while I breed my little sister’s cunt.’ Amber asked something about the TV show, her voice muffled through the wood.
Sam’s eyes rolled back, control snapping. He fucked me like a beast, hand clamping tighter, pounding my folded body into the floor. The angle hit every spot, my pussy spasming, tears streaming as pleasure built against my will. ‘Almost done, Amber— you can start the next episode,’ he grunted to her, but to me, in a whisper, ‘Take it, sis—milk my cock while she waits.’
I came hard, sobbing into his hand, walls convulsing, but he didn’t stop—thrusting wild, talking casual to her about the show. ‘Fuck, yessss—’ he hissed low, swelling inside me. Hot cum erupted, flooding my pussy in thick spurts, filling me up as Amber laughed outside, clueless. He kept pumping, emptying every drop, my body shaking under him, the door still locked between us and the world.
