Phil muttered something and stared at the ceiling. Karen lifted the towel off, exposing her teenager's prick. Then she felt her pussy burn with lust, and she knew that soon she'd have to take his cock down her throat.

His was a big prick. Phil's prick was flaccid, but hung on the hairy, wrinkled sac of his balls like a thick tube of meat, capped by a fat, spongy cock-knob. Karen soaped the washrag all around his well hung prick, never taking her eyes off his prick.

Then she sponged his balls, and then, saying something to the effect that his prick got dirty too, she started to wash his prick.

And immediately his prick started to get stiff. Phil's face contorted miserably with humiliation, but there was no restraining the hot swelling of his cock. Within seconds his prick was throbbing and as hard as bone, rising out of his short hairs to quiver lewdly over his stomach.

"My heavens, Phil," Karen said, suppressing a nervous giggle. "I didn't know a washing would get you so excited."

"I'm really sorry about this, Mom," Phil said, blushing crimson. "This is so fucking embarrassing."

"But there's, nothing to be embarrassed about," Karen replied and clenched the washrag around the root of his prick. "To tell you the truth, I had no idea you were so well endowed."

She was losing control of herself, but she had no desire to resist her fuck urges anyhow. Lightly Karen moved the washrag up and down Phil's prick. His cock responded by throbbing stiffer than ever, twitching and jerking painfully over his navel.

"God, Phil, you really do have a hard-on!" Karen laughed. "It's been years since I've seen your fathers cock so stiff. Don't any of your little high school girlfriends give you any sexual relief?"

"It don't make any difference," Phil said miserably. "I'm horny all the time."

"I'll bet you are, darling. You're a teenager. But you should try to get laid more often. It's not healthy to walk around with such an enormous boner. You need a… release."
