so we were 5 people that night. me 25 m, my younger sister 23 f, her boyfriend 25, and her two close girl friends. we all went to club around 10.30 pm. music was blasting so loud the floor was shaking. we danced for like one hour straight, bodies all sweaty, everyone laughing and grinding a bit. but after that we were so tired. legs hurting, throat dry. so we found this corner booth with a long black table cloth that went almost to the floor. we sat down and ordered dinner and just started chatting normal stuff like work and movies.

my sister was wearing the tight black one piece dress. her body is 36c-30-34 and the dress was hugging every curve. neck was not too deep, just little cleavage showing. but the dress was short, when she sat the hem was barely covering her smooth thighs. skin still glowing from dancing, little sweat making her shine.

i was sitting right opposite to her and her bf. the two girls were next to me talking something. thats when i noticed. her bf hand went under the table cloth. at first it looked normal, just on her bare thigh. but slowly slowly his fingers moved up. inch by inch. my sister was a little tipsy, three drinks down, cheeks all pink, eyes little glassy. she didnt stop him. instead she shifted in her seat and opened her legs a bit more.
the table cloth hid everything. nobody else could see but i could.

i watched as he pushed her dress higher till it was bunched at her hips. his fingers playing with the edge of her small black lace panty. my sister breathing changed. she was still smiling and nodding to the girls but her chest going up and down fast. then she spread her legs wider, one knee even touched my leg under the table by mistake. she didnt pull back.
his hand went inside her panty.
i saw her body jerk a little when his fingers touched her bare pussy. she was already so wet. his fingers rubbing her soft lips in slow circles. her swollen clit was throbbing i could tell. she bit her lip hard trying to act normal. but her thighs were shaking. guilt hit me hard right then. god she is my own real sister. how can i sit here and watch this. this is so wrong. i should look away. i should feel disgusted. but my dick was already rock hard in my jeans, pushing against the zip. throbbing like crazy. i felt like a total pervert. what kind of brother gets turned on by his little sister getting fingered in public. shame was burning in my chest but i couldnt stop staring. i told myself just look away but my eyes stayed glued.

he slipped one finger inside her. i could imagine how tight and hot she felt. then second finger. he was curling them, rubbing that spot inside. my sister hips started moving tiny movements, grinding on his hand. her skin was so hot, flushed red. nipples hard and poking through the thin dress. pussy dripping so much his wrist was shiny when light hit it. i kept thinking this is my sister, blood related,and now im hard as fuck watching her pussy throb. guilt made it even worse, like the taboo was making me harder. i hated myself but i kept watching every second.

she was close. her legs shaking more. pussy clenching around his fingers. then it happened. she came hard. body tensed, thighs quivering, a tiny soft moan escaped but music covered it. her juices gushed on his hand. she tried so hard to keep face normal, laughing at something her friend said.

after few minutes he pulled hand out and wiped on her thigh like nothing. they both thought nobody noticed.

later when we reached, my sister face still bit red, hair messy. she looked straight at me and said soft, "he knew you were watching whole time. i scolded him so much in the cab. called him pervert for doing that in front of you."

she laughed little, shook her head, like she was embarrassed but also mature about it. then she gave me this long look, half shy half something else, and went to her room.

now its been days and i still cant forget. every night i remember her swollen wet pussy, the way she spread for him, the way she came so hard while pretending nothing. guilt is eating me. i feel ashamed, dirty, like im a bad brother. i keep asking myself why did i watch, why didnt i stop looking, why does remembering make me hard again. maybe the guilt makes it hotter, the forbidden part. i dont know. she handled it so mature, like its no big deal now. but for me its stuck in head. i feel guilty every time i get turned on thinking about it. but i still get turned on. its like a loop i cant break.
anyway thats the whole thing.
