"Oh, yes, yes! Don't stop, please!" And he humped the bed even faster and harder.
"B-Bill? Remember when I-I caught you in the bathroom, and got mad at you? Well, I was upset. It was a terrible thing for me to do. Playing with your penis is perfectly normal, just like breathing."
Bill said nothing, but his hunching slowed a bit. Kim's hands continued to mold the supple flesh of his ass, but she did it absent-mindedly while she strained to find the right words.
"And when you hurt yourself, and got excited and squirted your stuff, well, that's what happens when you don't play with yourself often enough, I guess."
She waited for him to say something, but only silence punctuated by an occasional moan answered her. He just kept humping the bed, and Kim gave in and bent down and shamelessly admired her boy's big balls. Their heat hit her face, and their strong male scent filled her appreciative nostrils, and her lips went dry with desire.
"Ohhhh," she moaned softly, and wet them, then left her tongue out and, where her knuckles had bumped, she briefly touched with her tonguetip.
As she'd hoped, Bill, didn't notice the light touch, and now she knew what his balls tasted like! Oh, God, she must be sick! How could she have done such a depraved, sinful thing! But the exciting nearness of his cock, and the memory of its impressive size and strength beat down her lingering conscience.
"Bill, you're playing with yourself right now, aren't you?"
There was a moment of silence, then Bill said, without opening his eyes or halting his movements, "Yeah, I, uhh, I can't help it."
"I understand," Kim whispered. Then, "I play with myself, too!"
She hadn't meant to tell him that. It had just come out, and now it was too late to take it back.
On a sudden impulse, somehow knowing it was now or never, she took the plunge. She cupped her son's hot, spongy balls and rolled them like dough between her sweaty palms.
Bill jumped and groaned, and she whispered, "Would you like Mom to help you cum?"
Bill's body went rigid as his beautiful mother's soft hands played with his aching balls. He'd never thought anything like this would happen. He'd thought that's all daydreams were – daydreams. He was finding out that some daydreams come true, if you work at them.
Kim took one hand from his big balls and slid it under his belly until she felt the heat of his cockshaft against her palm. Then she made a loose fist and let him fuck her hand while she rolled his balls and tugged on them.
"Oh, Jeez!" Bill cried. "Mom!" And he rolled over onto his back.
Kim had to let go when her son rolled over, but as soon as she saw his gigantic prick swaying heavily before her, she grabbed it again and rubbed it briskly up and down.
"My balls, my balls!" Bill cried.
Kim's other hand reached for her boy's hefty balls, but her eyes were glued to his enormous, throbbing cock. The spongy, purplish head of that nine-inch wonder was shiny, and its wide slit was drooling large, clear streams of pre-cum.
"Uhhhh, Mom," Bill groaned as Kim's soft fingers squeezed a bit too hard.
Kim felt her stiff clit twitching. Her hungry, aching pussy was already overflowing with slippery, fragrant cunt-juice. She wanted more, but couldn't bring herself to release his cock and balls long enough to make her needs known.
The muscular heat of her son's magnificent hard-on burned the crazed mother's sweaty palm. Even the juice seeping from his piss-slit was hot! She felt the cords and veins of his wrist-thick cock, and felt her senses reeling.
Frantically, she grabbed Bill's enormous cock with both hands and began pounding it with insane force. "Cum, cum!" she chanted mindlessly, her glazed eyes focused on the expanding cockhead. "Cum, Son, cum. Ohh, shoot off all over me again! Give Mom your cummmmm!" The side of her bottom fist hit his balls on every powerful downstroke, making him grunt.
Bill went wild when he heard his beautiful, fat titted mother begging him to squirt his hot load all over her. He saw her creamy tits jiggling half out of the bikini, and the realization that he could now do what he pleased suddenly hit him. With a groan, he lifted his upper body and buried his face in their soft, spongy cleft.
"Ohhhh, Mom!"
The sound of Bill's voice muffled by her warm, scented tit-flesh excited Kim so much that she took a hand from his cock and ripped off her bikini. There was an actual physical relief at having her heavy tits jiggling freely around her son's hot face.
"Yes, yes!" she cried, shaking her shoulders and massaging Bill's cheeks with the inner curves of her firm, jelly-like tits. "Suck them!" she begged, lifting one and guiding it to his lips.
The minute Kim felt the liquid heat of her son's mouth surround one long, hard nipple, her clit stiffened and twitched. Her hungry, aching pussy was already overflowing with slippery, fragrant cunt-juice.
"Mmmmm-uhhhhh!" Bill moaned around his mother's huge nipple. His senses were like overloaded circuits as he filled his hands and mouth with his mother's huge, rolling tits while her soft fingers threatened to pull the cum right up out of his fat, tight balls.
Eagerly, he kneaded her creamy, spongy tits while nursing her fat nipple. The heavy, satiny titflesh felt like nothing else he'd ever experienced. Soft, so very soft on the outside, but with a firmer core. And her nipple! It was so wide, so hot, and the wrinkled, goose-pimply skin surrounding it so rough, that his tongue went crazy.
"Mommmmm!" he cried through the fullness of one tit. "Gonna cum! Gonna… CUM!"
Kim heard her son's almost painful cry, but she would have known he was about to cum, anyway. His thick, jerking cock was trembling beneath her squeezing fingers, and she felt the cockshaft suddenly shrink, then swell again. His purplish cockhead grew even fatter, the eye opened wide, and Kim pumped faster.
"Aghhh, uhhh, ohhhh."
Bill's spasming prick jumped in his lovely mother's small hand, spewing a succession of cum wads onto her belly and tits. The hot, sticky jism gathered on her big, shaking tits and then dripped onto her thighs. Kim continued to milk her son's fat, softening cock as thin, watery cum-oozings dribbled over her fist.
Bill had thrown back his head and collapsed on the bed as his cock erupted in his mother's fist. He'd never cum so long and hard, and his balls felt great, pleasantly tired, as if he'd jerked off three or four times instead of just once. He looked down at his sweaty, cum-smeared groin.
"Mom?" he said as she continued to pull on his heavy cock.
He slowly reached between her jism-dotted thighs, and Kim spread her legs for him. Her bikini bottoms were soaked with her cunt juice, and her inner thighs were shiny. Bill could smell his mother's hot pussy, and his cock sprang to life.
His cock hard, his body burning with a lust he'd never felt before, the teenager grabbed his mother's last scrap of protection and ripped it from her body.
"Oh, Jeez!" he exclaimed, staring at her exposed cunt. She appeared quite hairy to him, but the fat pink lips of her pussy jutted boldly from the center of all that soft, thick hair. And at the narrowing folds at the top of her slick cunt he could see a throbbing, finger-like protrusion. He touched it.
Wide-eyed, hardly believing such a thing was actually happening to her, and that she was allowing it to happen, Kim moaned and gave in to her sons inquisitive fingers.
Bill looked up and saw his mother's eyes close, and at the same time he felt her lift her cunt toward his fingers. Happily, he let his fingers race up and down the hot, slippery, hair lined lips of his mother's naked pussy. Puddles of cunt-juice collected beneath her partially flattened asscheeks, and her churning hips soon smeared the juice in wider circles.
"In, in," Kim moaned almost incoherently, stretching her legs out and sagging to the bed. Bill saw her big tits softly spreading over her chest, rolling toward her arms; he caught one in his free hand and held it.
