She supposed her appearance had something to do with it. Patty was slimmer than average, with long legs and a cute, girlishly round ass. But her tits were so big that most of her bras had to be custom-made. Her body had always made men horny, and Patty was afraid that her only child was no exception. She had been mortified to see his cock swelling many times in the past six months, when she caught him ogling her figure.

At least he could try to restrain himself, Patty thought. Or at least be quiet about wanting to play with himself so much. It was three-thirty in the afternoon now, and Walter had been home for a half hour. He'd literally run upstairs as soon as he'd walked through the door with an obscene-looking bulge tenting through his slacks.

Two minutes later, the thumping had started. She heard it at least four times a day now. She'd tried to talk to him about it, both gently and sternly, but he just wouldn't listen. All he said was that he couldn't keep from rubbing his big prick as soon as it started to get stiff.

Well, he was just going to have to learn to ignore it, Patty thought suddenly. Impulsively she went to the hall closet, finding the key to Walter's bedroom door hanging on a nail. Determinedly she went back to his room, knowing full well that she was about to catch her boy in the act. It wasn't normal for a lad to play with himself so much. Walter simply had to learn to control his sexual desires.

Patty let herself into his room. It took Walter a moment to notice that she'd come in. As she'd expected, he was lying on his back with his pants around his ankles. A jar of baby oil stood prominently on the nightstand beside his bed. The youth's tongue lolled obscenely out of the corner of his mouth as he worked his fist feverishly on his crotch, whipping his hand up and down his throbbing, straining cock.

Patty looked at it. It was the first time she'd ever seen her son's naked, stiff prick; in spite of herself, she couldn't help being curious. She'd imagined that he'd have a relatively small prick, even though he was almost full-grown.
