"Mom, Mom!" Bill cried, more than a little frightened by what he had done. Now that his horniness had passed, he became rational enough to fear his mother's anger.
"I didn't mean it!" the boy cried. "It was an accident, honest!"
Kim shivered and looked at her handsome son's stricken face, forgetting for a moment that her own face was still streaked with the glistening contents of his plump balls.
"I-I understand, Bill," she said, robot-like, remembering the lecture Nancy had given her about guilt. "I-I don't want you to feel bad or – or to worry about it. It's natural for a, uhh, guy to sort of, ahh, accumulate so much of that stuff that it just, uhh, jumps out without much help."
Kim drew a deep, shuddering breath as the fear in Bill's eyes faded. She hoped he wouldn't notice the growing wet spot in the crotch of her bikini bottoms. "Go inside, in the bathroom, I mean, and clean up and put some iodine on your cuts. I'll finish up out here."
But when he left, Kim quickly wiped her face with the fingers of her left hand and sucked the cooling jism from them while her right hand cupped her soaking cunt.
Thank God her back yard wasn't visible to the neighbors, Kim thought, as she stroked her hard clit. Sweat streamed down her face and thighs, and a flood of cunt-cream fell into her cupping palm. "Uhhhhh, gonna cum-m-m-m!" she groaned, shaking her shoulders and hips. Her big tits heaved like jello, then flopped heavily over the cups of her bikini.
"Ohhh, Bill, Bill!" she groaned as she climaxed.
There were two horny guys and two horny women at the supper table that evening, but everyone did their best to conceal their feelings. Jack's cock stirred, lengthened and hardened. He had to jerk off, but forced himself to wait. With his mother, wife and brother in the house, there was too much chance of being interrupted. But the thought of waiting until bedtime to get some relief was pretty unpleasant. But he waited, and his hard-on eventually wilted. But it came back again before dessert.
Bill, too, was hard enough most of the meal, for Kim and Mary both had dressed for warm weather, and everywhere he turned he saw a pair of juicy tits resting on the tabletop. He was too concerned with his own incestuous thoughts to notice that Jack had the same problem.
Mary was the only member of the family whose face wasn't flushed with more than the heat, but even she was suffering from a case of wet panties. Although she needed a good fuck, she'd never be so shameless as to hint at such a thing. In fact, she'd never used the word in her life, and cringed whenever she heard it.
But fucked was what she needed, and she knew it. She pressed her sticky thighs together as she ate, mechanically chewing her food as she milked her plump pussylips and stimulated her itchy clit. But she was too nervous to cum. There were too many people around. She'd wait until later, then bring herself off with her fingers.
Mary hated to masturbate, believing it to be not only sinful, but a sign of moral weakness. But it was less horrible than going to Jack like a bitch in heat and asking him to stick it to her. She wished Jack would get a job and let things return to normal, but it didn't look as if things were headed that way. She sighed and asked Kim to pass the salt.
After supper Mary visited Nancy, and Jack left to hang out at the local bar with some friends. He figured that a few drinks would help relieve some of the pressure in his balls. He was wrong.
Kim and Bill returned to the garden, both studiously ignoring the other's body. But Kim had put her bikini back on, and Bill had on a new pairs of trunks. The boy wasn't used to bending and kneeling so much, and from time to time Kim saw him stand and stretch and rub his lower back.
"What's the matter?" she joked when she heard him stifle a groan. "Can't keep up with your old mother?" She was trying to lighten the atmosphere between them, but it didn't work.
"Guess not," Bill said, wincing as he stretched again. "Anyway, you're not old."
"Well, sometimes I feel pretty old," Kim said. "Listen, you go in and soak in a hot tub – otherwise you'll really be sore tomorrow."
"Yeah, think I will," Bill said. Kim watched him enter the house, and couldn't help but think about her boy sitting naked in the bathtub, maybe with his thick prick jutting from the water.
Kim weeded and watered and gradually headed for the back door. She wouldn't admit it to herself, but she was hoping to catch a glimpse of her son's massive cock again.
She tiptoed down the hall, but he wasn't in the bathroom. She hesitated for a moment, confused by this unexpected occurrence. Then she saw the beads of water on the bottom of the tub and realized that he'd finished sooner than she'd expected. Disappointed, Kim slowly walked down the hall toward his bedroom. She saw the door was open and slowed, causally turning her head.
Bill was on his stomach on the bed. Except for a towel draped across his behind he was naked, and facing her, his head resting on his folded arms.
"Oh, hi, Mom," he said. "That hot bath helped a bit, but I think I'm still gonna be sore tomorrow."
Kim looked at her boy's handsome face, then at the towel covering his lean, muscular ass. She knew what was trapped between his belly and the bedspread, and her cunt began to itch and dribble. Then her clit poked its head against the material binding her wet crotch. She knew her will was weakening.
"Would-would you like me to rub your back a bit?" she asked.
Bill's eyes met hers briefly, then dropped; he nodded. "Yeah," he said softly, "maybe that'll help."
Eagerly, the hot-assed mother sat beside her scheming son and began kneading his shoulders. Bill groaned with mingled pleasure and anticipation, and she could actually see his tense muscles relaxing under her massaging fingers. She worked her way down his spine, slowly, until she was at the edge of the towel. She was hesitant about going lower, but she didn't want to return to his shoulders.
"How's this?" she asked in a strangled voice, compromising by slipping her hands to Bill's ribs and then to his hips.
Gradually, she became aware that Bill's ass was moving, and she carefully studied him. Yes, his ass was lifting and dropping ever so slightly-hunching, poking his prick into the mattress! Her big cocked son was actually fucking the bed with his naked prick while she was with him!
The thought of that beautiful, fat cock all long and hard and eager to squirt its load of hot cum erased the last vestige of her self-control. Her hands returned to his lower back, then slowly slid under the towel to squeeze his bare ass.
"Oh, yeah," Bill groaned as his mother squeezed and pushed against his asscheeks. "That feels great, Mom!"
Kim saw his legs slowly part, and felt him lift his hard-muscled ass to meet her hands. She cupped both of Bill's asscheeks in her small hands, squeezing and rubbing them, and pushing down gently in time to his fucking movements. And as she helped him, neither of them noticed that their movements were becoming more noticeable, that Bill was fucking faster, and Kim was pushing his ass harder into the mattress.
CHAPTER THREE
Bill's eyes were closed, and he continued to hump the bed with more and more vigor. Kim finally realized how exaggerated his motions were, but thought that he was so far gone in his sexual fantasy that he didn't realize she could notice what was going on. Her busily working fingers quickly caused his towel to slip from his ass, and now his bare ass was exposed to her greedy eyes.
"Oh, Mom…" Bill groaned as she slid her hands onto his parted thighs. His legs parted even more, offering a full view of his cum-filled, rosy balls.
"Does-does this feel good?" Kim asked weakly. She worked on the insides of his upper thighs, her knuckles brushing against his swollen balls.
