"Yes, yes!" Shari yelped, grinding her naked little ass instinctively. "Ooooo, Bobby, fuck me! Mom… Mom, this is so good, so wonderful! I love this, Mom!"

Joyce's eyes blazed hotly, seeing her son's cock fuck in and out of her daughter's grinding cunt. It was so lovely, so exciting. Her own pussy was bubbling hotly. She squirmed her ass on the couch, cooing softly as she watched her two young children fucking. Her tits became swollen, her nipples extremely hard and tight. As she watched them, seeing Shari's delicate cunt lips stretching about Bobby's cock, she began to fondle and caress her own tits, digging her fingers into her firm flesh. She was panting for breath, just as loudly as Bobby was. Shari was whimpering with pleasure, her chin against her chest as she arched her cunt up, trying to see her brother's throbbing cock slide in and out of her.

"Fuck her cunt, Bobby!" Joyce urged, her voice very husky with excitement. "Fuck her little pussy! Oh, God, that's so beautiful! Fuck her with your sweet cock, honey! Grind your ass against him. Shari! Wiggle your little ass, baby!"

"Ooooo, I am, I am!" Shari wailed as the burning ecstasy flowed through her. "Oh, I am, Mom! Faster, Bobby! Fuck me faster and faster and faster! Ohhhhh, I love fucking! I love it… love it… love it!"

"You like that cock in your cunt, Shari?" Joyce asked, clawing at her own tits brutally. "You like your brother's cock fucking you?"

"I love it, love it!" Shari yelped as she threw her ass up and down. "Oh, Mom… I love getting fucked!"

"Bobby," Joyce asked her son, her eyes blazing down as she watched his glistening hard cock fuck back and forth in Shari's pussy. "Do you like that cunt! Do you like your sister's hot, wet cunt!"

"Yes, Mom!" he shouted through gritted teeth. "Oh, damn yes!"
