Then Biff remembered something else about the long-forgotten scene. Marge had begun to make a strange sound as she rubbed her cunt. And, as he listened to her voice now, he remembered that sound. It had been a sort of whimper.

Biff remembered that he had been scared as he stood watching Marge jerk off. She looked so strange moving like that, and her whispering was so much like a cry of pain.

"You should call Sandy," Marge was saying now. "I'm sure she'd like to hear from you. And you wouldn't believe how she looks. She has such a pretty figure. I've always wanted an ass like she has now."

Biff couldn't believe Marge was talking to him that way. Mentioning her daughter's ass to him gave Biff a rush that brought his jism surging.

"Uh-h-h-h," he gasped into the phone.

Huge, wet drops of jism began to fly from his prick as his fist moved rapidly up and down.

"What?" Marge asked. "Did you say something?"

Biff knew that she had heard him gasp. It would have been awfully embarrassing if she knew what he was doing as they talked.

And as Biff's embarrassment began to replace his lust, he remembered one more thing about that scene from long ago.

Marge's moans had begun to get louder as he stood outside her bedroom door and watched. Then, suddenly, she stopped moving and her moans ended. Biff had begun to retreat from the doorway. But Marge suddenly looked toward him.

He could remember how shocked she had looked when she saw him there. Suddenly, he knew that not only had he seen something very strange, but he had seen something that he wasn't supposed to have seen. The look on Marge's face told him that.

"Well, it was nice talking to you again, Biff," Marge was saying. "And tell your mother I called."
