Shari pulled her hand from her brother's cock.

Barry stood, his prick sticking from his shorts, quivering up and down. Janet saw his piss-hole drip.

Barry moved toward her.

"No," Janet moaned. "Please, don't… go away! Barry I'm your mother! Don't! Leave me alone, please! Oh, please, don't!"

But Janet didn't move, she stared at her son's cock as he approached her, her eyes filmed with desire.

Barry stood close to her now, and Shari had joined him. Shari lifted the book from Janet's lap, and Janet sat passively, waiting, knowing what was about to happen and that she was powerless to stop it.

"Let's look under her dress," Shari said. "Let's take a look at her cunt, Barry."

"Shari, don't, please!" Janet sobbed. Barry lifted his mother's dress high. Both Barry and Shari peeked, seeing her long legs, her panties. Janet pressed her thighs together, a feeble effort to conceal her cunt.

"Let's see her tits," Barry said.

"Yes, I wanna see how big her tits are!" Shari giggled, and her hands pulled their mother's sweater up to her chin.

Janet sat stiff, trembling. Her bra was filled tightly, but that didn't prevent Shari from shoving the cups upward, exposing her tits. Tears came into Janet's eyes, and she tried to keep them closed, to keep from staring at her son's cock. But she couldn't close them, couldn't stop looking at his hard-on. She heard her daughter and son gasp as they gazed at her revealed tits. She had full tits, round and firm, with stiff nipples. Her tits stood out proudly on her chest, succulent and satiny.

"Daddy said Mother loved to have her tits sucked," Barry said, his voice sounding awed. "Wanna try it, Shari? Wanna suck her tits?"

"Please," Janet cried softly, lifting her hands and cupping her naked tits. But Barry pulled her hands away. They had released her skirt, but the hem was high on her long, slim thighs, almost at her lap. When her son pulled her unresisting hands from her tits, she looked up at him, pleading in her wet eyes.
