"Just how many boys have you been fucking, Pamie?" Susan asked.
A cute blush crept over her daughter's face. "Only – come on, Mother. A girl has to have some secrets."
"Two," Billy laughed. "She fucks two boys, Mother. Besides me and Bob, that is."
Susan gazed at her young daughter. She wondered how long all this had been going on, who the other two boys were, and where it was happening. There was something here she was unaware of something her daughter and sons were involved in. She imagined Pamie, sweetly naked, being fucked by four boys, one after the other. From what she witnessed only a short time ago, she had no doubts that her daughter was a willing participant.
"Who started this?" she asked.
Both Bob and Billy pointed at Pamie, who flushed and lowered her eyes bashfully.
"I should have known," Susan said, smiling at her daughter.
Pamie pecked at her mother from lowered eyes, her face pink, but those blue eyes were sparkling mischievously.
"The way you fucked Bob should have told me that."
"She's a little hot ass, Mom," Bob said, moving to his sister and rubbing his cock about a hard little tit. "If she'd just let us come in her cunt, she'd be a perfect fuck."
Billy climbed onto the table, and standing on his knees, rubbed the head of his cock about his sister's cheek. Pamie shivered, taking hold of Bob's cock and pressing his prick to her creamy, small tits, breathing deeply. It excited Susan to see them doing these erotic things. She was getting her answer about Pamie fucking them together or separately.
Pamie started jacking Bob's cock, pressing his piss hole against one of her rigid, pink nipples. When Billy dragged the swollen head of his cock across her cheek, Pamie gave a low moan and brushed her lips across it. Susan's eyes burned upon her daughter and two boys, her cunt starting to throb wetly all over. She slipped her hand down the back of her thigh, moving a fingertip to her swelling cunt. She stroked her cunt gently as she watched them, her excitement bubbling deep inside her stomach once more.
