"Oh, fuck!" he gasped. "My thigh! It's killing me!"

"Sometimes the pain shoots down there," Sylvia said, wincing sympathetically. "It's normal."

"Oh, fuck!" Tony bit his lip. "It's like a knife!"

"All right. Turn over, honey. I better rub you there too."

Tony swiveled quickly onto his back, in so much pain that he didn't notice that the towel had almost fallen from his hips. Sylvia knelt beside him and briskly rubbed his upper leg. Slowly Tony relaxed.

"It… it's getting better flow," he sighed. "It was just this really sharp pain, just for a few seconds."

"That's what back spasms are like," Sylvia said, briskly rubbing and kneading his thigh, staring down at it. "Your leg probably won't hurt again tonight, I'll bet. The whole thing'll probably disappear tomorrow. Does your leg feel better now, honey?"

But Tony didn't answer. Several seconds passed, and Sylvia glanced curiously at his face. There was something strange in his expression now. His eyes were very wide. Why was he staring at her like that? Then Sylvia looked down at her body.

"Oh, Tony!" she gasped. "I'm so sorry. How careless of me!"

The carelessly-knotted robe had come completely open while she'd changed positions. Her son was staring helplessly at her naked body, at her dense pussy triangle and her round belly and what had to be the biggest firmest tits he'd ever seen in his life. Sylvia felt embarrassed to realize that her nipples were stiff, her fat tits protruding from the wide, crimson circles like eraser tips. She tried to close the robe hurriedly, but she was so nervous that she couldn't seem to grab the sash, and the movement just made her giant tits jiggle more seductively.

"Oh, darling, I'm so sorry! I should have worn my clothes, I… oh, Tony! Oh my Lord!"
