"Mmmmmmm, I'm going to love playing with your cock, darling."

Bobby trembled, grinning from ear to car. "You gonna let me touch your cunt, too, Mom?"

"You can touch me all over. Here…" She took his hand and slipped it under her skirt, between her legs, curling his fingers into her crotch. "Have a little feel of Mother's cunt now… and then later…"

"Bobby, your ice cream is gonna melt!" Sarah called from the kitchen.

"I don't want any ice cream!" he whispered, rubbing the wet heat of his mother's crotch with his palm, his cock swelling against her hand. "I wanna fuck you right now, Mom!"

"Go eat your ice cream," Linda purred. "We don't want your sister to get suspicious, do we?"

Bobby reluctantly went to the kitchen. Linda sat waiting, trying to think of something to get Sarah out of the house. She could hear them talking quietly.

"You're not a cunt-face, Sarah," she heard Bobby say.

Linda straightened up, listening. "What is a cunt, Bobby?" Sarah asked. "I know guys call a girl that sometimes, but what's a cunt?"

"It's what you have in your panties," Bobby replied. "You know, that thing you pee with. That's a cunt, Sarah."

Linda heard her daughter giggle softly.

"I don't think my face looks like that," Sarah said.

"You know what it looks like?" he asked eagerly.

"I look at it with a mirror." Sarah answered shyly.

"Show it to me, too!"

"You're talking nasty with me again!" Sarah giggled.

"You gonna tell Mom?"

"Maybe not this time."

Linda sat up, listening to them closely. She was surprised to find their conversation exciting. She stroked her tits as she listened, feeling her nipples erecting.

"If you're not gonna tell Mom, does that mean you'll let me see your cunt, too, Sarah?"

"I'm not supposed to let boys see it."

"Who said so?"

"Well… I'm not, Bobby. Besides, you're my brother."
