Bend over and Spill

Jack stared at his half-naked mother for a moment, taking in her figure as he thought over the consequences. Should he? Did he dare? Did he even care? Pussy - was pussy, his mother's, his sister's, his cousin's...

"Turn around and bend over," he commanded with a smirk. Without a word, she obeyed, presenting her posterior to her son, the white cotton edged with lacy frills stretched taut across her backside.

"Spread your legs a bit," Jack said. His mother widened her stance, giving him an eyeful of her puffy labia pressing against her panties.

"Okay," he began, "Now, run a finger over your pussy and don't stop until I tell you."

Silent, she complied, drawing a manicured finger up and down her nether lips, pressing the white cotton slightly between them. Jack watched, his grin growing as moisture slowly darkened her panties beneath her finger and as her breath quickened.

"Fan-fucking-tastic," the young man said softly. He paused for a moment, idly wondering if she had any thoughts or feelings about what she was doing. Would his mother react antagonistically if he stopped commanding her?

"What are you thinking about, Mom?" he asked.

"Nothing," she answered, continuing to stroke her flower. Jack wasn't too sure about her reply.

"Tell me the truth," her son commanded.

"I'm thinking about you," his mother said, shuddering slightly.

"How so?" he arched an eyebrow.

"I'm thinking about you fucking me with your big cock."

"Oh?" his eyebrows popped up in surprise. "Tell me why?"

"Because I haven't had sex since Kelly's father dumped me."

"What?" Jack exclaimed. His mother had been single for as long as he knew, but he thought his father - his and Kelly's father - had divorced their mother or something. Was Kelly his - half-sister? Did they have different fathers?

"Being a single mother of two children does not avail me to many willing partners, Jack," she said evenly. "It was easier to ignore you when you were younger, but... now that you're all - all grown up - I - I've been fantasizing about you."

"Have you told anyone about your - attraction - to me?" the young man asked.

"No," his mother shook her head slightly. "Who could I tell? The few friends I have wouldn't be sympathetic if I told them and most likely wouldn't have anything to do with me afterwards. As for your grandparents, we haven't talked since you were born. They were very upset with me when I found out I was pregnant and they wouldn't believe me when I told them it was - well - a miracle. I knew I had sex - my hymen was broken - but I don't have any memory of having sex or of the man I had it with."
