Chapter 1: The Perfect Popular Sister
Su Yuyan, 26 years old, was a top internet idol with millions of fans. She possessed a perfect face and an S-class devilish body — G-cup massive breasts, tiny waist, and a perky round ass.
She had an extreme brother complex toward her younger brother, Su Xiaoyu.
When Xiaoyu sadly told her he wanted to enter the city’s best elite high school, “Shengyao Academy,” but his grades weren’t good enough, Su Yuyan gently kissed his forehead and said:
“Don’t worry, Xiaoyu. Big sister is willing to do anything for you… even if it means using my body.”
That night, as she watched her brother sleeping, her eyes burned with obsessive love.
Chapter 2: The First Transaction (The Chairman)
Su Yuyan first contacted the chairman of Shengyao Academy — a 65-year-old bald, fat tycoon.
That night, in the presidential suite of a five-star hotel, she wore an extremely revealing black see-through lace lingerie set with garter belts and crotchless design. She knelt in front of the chairman and said seductively:
“As long as you can help my brother get accepted, tonight I am completely yours to play with.”
The chairman grinned lecherously and pulled out his short, thick, wrinkled cock. Su Yuyan suppressed her disgust, opened her glossy lips, and took it deep into her throat, sucking hard with wet, obscene sounds. The chairman grabbed her head and fucked her face roughly, drool and tears dripping onto her massive breasts.
“Not bad… The famous internet idol’s mouth sucks so well…”
He pinned her on the bed and thrust into her tight, wet pussy from behind, pounding her like a dog.
“Ah… so deep… Chairman’s cock is hitting my womb…”
Su Yuyan moaned loudly while secretly thinking of her brother. The chairman creampied her three times, filling her womb and mouth with thick, yellowish semen, and finally shot the last load all over her beautiful face.
The deal was done. The chairman promised to help.
Chapter 3: Gangbang Transaction with the Board Members
To make sure everything was secured, Su Yuyan proactively invited three board directors and the admissions director — four middle-aged men in total.
In the luxurious VIP room of a private club, wearing only a fiery red crotchless lingerie set, she knelt and said:
“Dear uncles… As long as you help my brother pass all the reviews, tonight you can play with me however you want… one by one or all together.”
The men swarmed her like hungry wolves.
One shoved his cock into her mouth, another slammed into her pussy from behind, while the other two groped and sucked her bouncing G-cup breasts, pinching her nipples hard.
“The famous idol’s slutty cunt is so tight… So many fans fantasize about you, yet here you are getting fucked by us old men…”
They took turns relentlessly. Some loved doggy style while pulling her long hair, some made her ride them, and some tit-fucked her massive breasts.
Su Yuyan was fucked to orgasm after orgasm, tears streaming down her face, but she still moaned sluttily:
“Uncles’ cocks are so thick… My slutty pussy is going to break… For my brother… please keep fucking me hard… Fill my womb…”
The four men creampied her a total of eight times. In the end, they spread her legs in an M-position and covered her swollen pussy, huge breasts, and pretty face with thick loads of cum. Su Yuyan lay in a pool of semen, her belly slightly swollen, her eyes glazed over.
Chapter 4: The Siscon Explosion After Returning Home
The night after the admission was approved.
After showering, Su Yuyan wore only a sheer white see-through nightgown and walked into her brother’s room.
She straddled the surprised Xiaoyu, pulled down his pants, and sat down hard on his young but rock-hard cock, taking him all the way inside.
“Ahhh—!!! Brother’s cock… so hot… so hard… It’s finally inside big sister’s pussy!”
Su Yuyan rode him like a madwoman, her massive breasts bouncing wildly as she slammed down again and again. The loud slapping sounds filled the room.
“Xiaoyu… Big sister did everything for you… I let several old men gangbang me… Their cum is still inside my womb… But the only cock I love is yours!”
The more she confessed the dirty details of her transactions, the more aroused she became. She came wave after wave, squirting all over her brother.
Xiaoyu, stimulated to the limit, grabbed her slim waist and thrust upward furiously, shooting his thick virgin load deep into his sister’s womb.
Su Yuyan orgasmed so hard her eyes rolled back. She hugged her brother tightly and whispered happily, “From now on… big sister belongs only to you… your personal siscon cum dump…”
Chapter 5: The Eternal Siscon Meat Slave Sister (Ending)
From that day forward, Su Yuyan completely surrendered.
During the day, she was still the elegant and popular internet idol. At night, she became her brother’s exclusive lewd sex slave.
Every night she would wear the sluttiest lingerie and beg to be fucked. She even started secretly letting her brother creampie her right before livestreams.
“Xiaoyu… Big sister only wants to be fucked by you for the rest of her life… For you, I’m willing to do anything…”
