I couldn’t believe how fucking hot my sister is. She’s absolutely stunning—long toned legs, smooth golden skin that glows, a tiny waist that curves out into the most perfect plump heart-shaped ass, and full perky tits that bounce teasingly with every move. Her face is pure sex: big sparkling eyes, soft pouty lips, and that sweet flirty smile she gives me that makes my cock twitch instantly. She knows she’s gorgeous, and the way she carries herself in those tiny outfits drives me wild with perverted thoughts.I waited until she stepped out of the shower and left the bathroom, then slipped inside like the depraved brother I am. The moment the door clicked shut, I spotted her old crusted thong crumpled on the wet tile floor, the crotch panel still molded perfectly into the shape of her juicy cunt. Thick, pearly-white creamy discharge had dried into glossy streaks and flaky patches, tracing every soft fold and puffy lip, with a deeper sticky spot right where her clit had rubbed all day. The fabric held the exact imprint of her pretty pussy like a filthy cast of her wetness.My cock was already throbbing hard. I snatched up the thong and shoved the crusted crotch straight into my face, burying my nose deep in the molded shape. I inhaled greedily, letting that warm, sweet, tangy scent of her wet cunt flood my lungs—rich feminine musk mixed with creamy girl-juice. “Fuck yes… smell your hot sister’s pretty pussy,” I groaned, dragging my tongue slowly across the dried crust, tasting the faint salty-sweet flavor while picturing her perfect body spread open for me.The scent was so intoxicating that I couldn’t stop there. I pulled my aching cock out and started stroking furiously while keeping the thong pressed to my face. It only took a minute before I was panting, balls tightening. I aimed the head of my dick right at her toothbrush sitting on the counter and blew a thick, heavy load all over the bristles—ropes of warm cum splattering and coating them completely, mixing with the leftover toothpaste. Some even dripped down the handle. I milked out every drop, making sure her toothbrush was thoroughly creamed with my load.Heart pounding with how fucked up this was, I quickly wiped the excess off my hand, stuffed the thong back onto the floor exactly where I found it, and slipped out of the bathroom, closing the door behind me. Her cunt stench was still thick and warm in my nose, clinging to my face like a dirty secret.The second I stepped into the hallway, I bumped straight into her.She was standing right there, fresh from the shower, drying her long wet hair with a towel. She wore nothing but a tiny pair of tight booty shorts that rode high on her smooth thighs and barely covered the bottom curve of her perfect ass. Her perky tits jiggled under a loose tank top, nipples faintly visible through the thin fabric. She looked so fucking sexy and casual.She smiled at me with that sweet, everyday sisterly smile, still rubbing the towel through her hair. “Hey bro,” she said in her normal, cheerful voice, exactly like she always talks to me. “You okay? You look a little flushed.”Her big sparkling eyes locked on mine while the heavy stench of her own crusted cunt was still burning deep in my nose, mixing with the memory of my cum on her toothbrush. I could still taste her dried pussy cream on my lips from licking the thong.“Yeah… I’m good,” I mumbled, trying not to stare at how those tiny booty shorts hugged her plump pussy mound.She tilted her head cutely, still smiling. “What’s for dinner tonight? I’m starving.” Her voice stayed so sweet and normal, completely unaware (or pretending to be) while my face reeked of her wet cunt and her toothbrush sat there covered in my fresh load mixed with her own dried discharge.Before I could answer, she gave me a little wave and headed back toward the bathroom. “I’ll be quick—I just need to brush my teeth before bed.”I froze in the hallway, cock still half-hard, as she disappeared inside and closed the door. A minute later I heard the faucet running, then the soft brushing sounds. She was brushing her teeth with my cum smeared all over the bristles, probably tasting the salty mix blended with whatever was left of her own crusted pussy juice from the thong I’d rubbed on it earlier. The thought made my stomach twist with perverted shame and lust.A few minutes later she came out, lips shiny, still in those tiny booty shorts and tank top. She walked right up to me, smiling brightly as she flipped her now-dry hair over her shoulder. “Goodnight, bro,” she said in that same sweet, casual voice, leaning in just a little so her perky tits brushed close. “Sleep well. See you in the morning.”
