"Does it bother you, fucking your son?" Wanda retaliated, and squeezed Susan's tit hard enough to bring a low moan of pleasure from Susan.

"No," Susan said, her voice hoarse.

Wanda rested her other hand on her stomach, and was making slow, gentle circles with it, her fingers slipping under the sheet.

"Being your sister doesn't bother me, either," Wanda murmured, and slipped her fingers through the soft hair of Susan's cunt. "Open your legs for me, Susan."

"What if Tommy comes and catches us?"

"Would you really mind?"

Susan thought about it. Wanda was twisting at her nipple, her pretty face lowering toward it.

"No, I wouldn't mind," she finally said.

Her legs opened, and Wanda shoved her palm across her older sister's cunt, feeling it.

"Nice and hot and wet," Wanda purred as she rubbed at Susan's pussy. "I like a cunt when it's hot and wet this way. I bet you have a real sweet cunt to suck, Susan."

Susan didn't reply, but her hips twisted beneath her sister's moving hand. Wanda's eyes took on a glassy expression as she lowered her mouth to one of her sister's tits. Susan watched her pink tongue swirl about her nipple, feeling the wetness scar it. Wanda closed her lips about Susan's nipple, sucking it gently, her hand constantly rubbing between her thighs.

Susan remained passive, her hands at her sides, but her hips twisted as her sister rubbed and poked gently at her cunt. When Wanda slipped a finger into her pussy and stroked in and out, then brought it to Susan's throbbing clit. Susan gave a soft gurgle of pleasure.

"Mmmmmm, you like it, I see," Wanda said, lifting her face and flicking the tip of her tongue from one nipple to the other. "If you like the way I suck your tits, you're going to love how I suck your hot, wet cunt, Susan."
