Her family makes her suck her brother's cock

Jenny's father and mother exchanged glances, nodded, and then looked at the alarmed teenager.

"You will suck your brother's cock RIGHT NOW," said her mother, "or you can forget about Cum Guzzlers --"

"Rum Guzzlers," corrected Jenny.

"Don't interrupt your mother!" said her father loudly. "And don't try to be funny. Rum Guzzlers? Ridiculous."

John still had his cock out and he was giving his sister a smirk. It had always been him getting in trouble growing up, Jenny always being the favorite. He was quite enjoying seeing her get talked to sternly by their parents.

"Go on," continued their mother. "I said suck his cock!"

Jenny's eyes welled with tears. She felt completely traumatized and didn't know how to get out of this insane situation.

"I'm warning you," said her father. "If you don't start blowing your brother, there's going to be some serious punishment."

Swallowing hard, Jenny blinked back tears and slowly lowered herself to her knees.

"That's better," said her mother in a warmer voice. "But unwrap your towel. Your brother wants to see your gorgeous tits and body while you suck him off, isn't that right, John?"

John nodded eagerly. He was dying to see his sister's big tits jiggling as he fucked her face deep and hard. He smiled wide as she reluctantly dropped the towel.

"Go on then, son," urged his father. "Once she gets a taste of your dick, she won't be able to stop. That's how your mother was when we were your age." He grinned at his wife and she winked at him. John didn't need to be told twice. As their parents watched approvingly, he pushed his cock in his sister's face.

The miserable teen opened her mouth. That was all that her brother was waiting for. He grabbed her hair, held it tight, and **** his dick inside his sister's lips. She gagged loudly as he shoved himself further, giving her the first experience of a cock roughly pushed into her throat. Jenny's eyes bulged and she made gurgling noises as John groaned.

"That's it, son," urged his father. "Give it to your sister good." He smiled at his wife. "Isn't it great to see how they've grown up."

"Oh, it is," she said, and she reached over to rub him through his pants. "Reminds me of when we first started dating."

Jenny's mind was already close to broken. Her brother was throatfucking her with increasingly hard strokes, at the urging of her parents, who were getting all nostalgic and romantic watching the sight. The poor teen couldn't handle what was going on. Her 18th birthday was supposed to be amazing. Instead, it was turning into a horrific nightmare.

"Oh, fuck yes," moaned her brother as he pleasured himself in his sister's wet throat. He held her hair in a tight grip, hammering away as he liked, using her face as his toy. He was so excited to get his first blowjob from his sister that he didn't last very long. A few more deep, rough strokes in her hot throat and then he pulled out and spurted himself in her face eagerly.
