She didn't care what Tommy had for dinner, and Wanda could prepare her own food. She bathed and thought about the things that were happening so swiftly. She didn't regret any of it, though. She would have been fucking her son sooner or later, she knew. The sexual tension between them had been building quite swiftly for weeks. When she thought about it, she realized she didn't give a shit that Wanda had peeked in at them, either. She knew, when Monday came and she had to go back to work, leaving her sister and son alone in the apartment, Wanda would waste no time in getting Tommy's pants off, and his cock in her cunt.

She just hoped her son was up to it.

It was near midnight, and she lay in her big bed, tossing and turning, reliving the incident in the subway, seeing again her sister's hand wrapped about her son's cock, Tommy's hand inside Wanda's panties, seeing her sister openly and unashamedly fingerfucking herself. Her cunt seemed to be constantly throbbing, too, despite the three fantastic fucks she had enjoyed with her son.

It had been some time since she had enjoyed orgasm that she, herself, had not produced. And they had been wild orgasms, too.

She heard the door open softly, and turned to look. Despite the darkness, she made out her sister's body.

"Are you still awake, Susan?" Wanda whispered.

"Can we talk?"

Susan agreed, and Wanda slipped into the room, closing the door behind her. Susan felt the sag of her bed when Wanda sat on the edge. She sat up, too, leaning against the headboard, the sheet down to her waist. She was naked, the way she preferred to sleep.

"Can I turn the light on?" Wanda asked. "You might as well," Susan replied. "I can't seem to sleep, anyway."

When the nightstand lamp was turned on, Wanda found herself looking at her older sister's flawless tits. Her tongue moved across her lips.
