Quietly he opened the door of the master bedroom. Karen often took naps in the afternoon, and he didn't want to wake her.
She was stretched out naked on the bed, still a beautiful sight in any man's eyes. Tall, honey blonde, with a superb voluptuous body and big size 40-D tits, his wife was a treat to look at. It was just that he'd seen her so often.
She had the curtains closed, and the strong afternoon sun came through a filtered yellow, making her tan body glow. She lay on her side with her back to him. The large shapely rounds of her ass seemed to be quivering slightly. "Ohhh," she moaned.
"Honey?" said Bill. "Are you all fight?"
She flinched, then lay still.
When she didn't answer him, Bill assumed she'd been dreaming. He slipped off his swimming trunks and lay down beside her, keeping maximum distance between them. He wanted desperately to jack off, but he didn't want Karen to notice.
His cock was standing straight up from his belly, rosy stalk swollen taut, blue veins standing out. The purple head of his dick oozed big gobs of horny juice. Feeling childish and silly, he began to pump himself. He had to have some relief from that aching hard-on.
But, Jesus, what a stupid state of affairs. A gorgeous woman lay naked not two feet away from him, and a delicious little teenage chick was just outside – and here he was jerking off like a guilty teenager.
Well, he couldn't have Stacy. A man couldn't ball his own adopted daughter. And it was no use trying with Karen. She seemed to have lost all interest in sex these past few years. Sighing, he pumped faster on his swollen throbbing stalk…
Hell, Karen was thinking. It was the very worst time for Bill to show up.
After leaving the others at the pool, she'd retreated to the bedroom for an urgent purpose, to bring herself off, to get some relief from the boiling sexual tension she'd developed from watching Mark. It was a silly infantile habit, masturbating, but it was the only thing she could do.
She'd stripped quickly, laid down on the bed, and eased a stiff finger between the furry wet lips of her pussy. She always started that way, stroking her hot little joy button, moaning softly. It felt so nice. In a while, when she was wet and eager, she'd use her fingers like a cock.
The real thing would have been much better, of course, but where was she going to get it? She lusted for Mark, but he was her blood nephew, her adopted son, and only a teenager. She'd have to be crazy to even consider making love to him.
No use asking Bill, either. He wasn't interested in sex any more, hadn't been for some time. Her only recourse was her hand. It made her ashamed to touch herself like that, but she couldn't stand the tension a moment longer.
Karen stroked her little slick clit, moaning and whimpering as sweet, hot sensations rippled through her belly. She thought back to the time when she and Bill were still hot for each other, the wonderful fucks they'd had, and her aroused cunt creamed heavily, wetting her stroking finger.
Where had that excitement gone? Once she and Bill couldn't keep their hands off each other. They were balling two and three times a day. She used to cream at the sight of him, but now she yawned.
And she letched for a teenage boy.
"Ohhh," Karen moaned, half in exasperation, half in growing pleasure.
Her finger kept up its good work, arousing her little wet clit into stiff sensitive erection. She rubbed faster, and juice sizzled from her hungry twat to soak her finger. Soon, very soon, she would slip that stiff finger lower into her seething pussy, slip it into her flooded cunt, pretend it was Mark's rigid young cock…
At the very thought of her sexy young nephew, she moaned again, louder this time, forgetting caution.
"Honey?" came Bill's unexpected voice. "Are you all right?"
Karen flinched in surprise. She hadn't heard him enter the room. Her face flamed. Fortunately she had her back to him, and he couldn't see her feverish eyes, her flushed face, or her shamelessly probing finger.
She slipped her soaked finger off her clit, closed her eyes, and pretended to be asleep. She was so aroused, so desperate, that she could hardly keep still. Dammit all, what a lousy time for her husband to arrive.
She waited, quivering with need, till she thought he was asleep. She just had to beat off, get rid of that tension. If she was very quiet about it, she might manage. At last, when she had heard no sound from Bill for several minutes, she quietly slipped her finger back onto the plump scorching button of her clit.
Bill noticed it again, the strange gentle rhythmic movements of his wife's richly curved ass. What the hell…! Was she having some strange dream? He heard her sighing softly.
He hoped she wasn't going to turn over and wake up. She'd sure as hell catch him in an awkward position if she did. He lay on his back, listing his erect cock, pumping himself like a horny kid. His dick was enormously swollen, drooling thick steamy juice.
"Ummm," Karen murmured.
Her sweet creamy-skinned ass continued its strange contortions, and then Bill noticed a little trickle of cunt cream progressing slowly down her thighs. He reddened. It didn't seem possible, didn't seem at all in character for his beautiful cool wife, but it looked very much like Karen was masturbating.
He felt a rush of disgust – till he looked down and saw his own fist pumping away at his swollen rosy meat. Christ, who was he to condemn her for something he was doing himself? He understood her need, too. It'd been weeks since they'd balled.
Bill watched her more closely, suspending his own movements. Her lushly curved hips and ass were grinding gently now, picking up the pace, and her breathing was hard and hot. From the movements of her arm muscles he could tell she was using her hand. No doubt about it, she was trying to bring herself off.
This is insane, he thought.
Husband and wife lying side by side, frigging themselves, hiding their need from each other – it was crazy. They might not excite each other so much any more, but they didn't have to resort to that.
"Karen," he said gently.
She flinched violently, and he could see her whole body redden. He understood. He'd be ashamed as hell if she caught him jacking off. Her hip movements stopped and she lay very still, faking sleep again.
He knew better. He moved toward her, letting his long rigid dripping prick lead the way. He snuggled his chest against her back, felt her soft creamy butt settling into his lap.
Karen had wanted to scream when he interrupted her the second time. She'd been so close to fulfillment, so close to the delicious moment when she'd ease her stiff finger into her soaked twat and fantasize that it was Mark. Bill's interruption couldn't have come at a more cruel moment.
Then she felt her husband moving on the bed, snuggling up to her. That familiar body, the broad hairy chest, the trim hips, the long muscular legs, pressed against her back. He was a handsome man even at forty, well-preserved, and probably very sexy-looking to other women. But he no longer turned her on, and she knew he was bored with her, too.
So what did he want?
She got her answer very quickly. She felt her husband's cock, hard and hot and throbbing, nosing between her clenched thighs.
"Bill?" she said drowsily.
She couldn't believe it was happening. He hadn't wanted her in weeks. The prospect of fucking him didn't particularly excite her, but at least she was ready. Thinking about Mark, frigging herself, she'd gotten juicy and violently aroused.
"Ssshhh," said Bill. "Let's just enjoy."
He wasn't turned on by the thought of balling her, either, but if he closed his eyes, he could pretend she was Stacy.
Karen had an identical thought at the same time. With Bill entering her from behind, with her eyes closed, she could pretend he was Mark.
"Yesssss," she whimpered excitedly.
She quivered as he eased his big swollen dick between her legs. He had a big cock, thick and long, something she'd always appreciated. It was going to feel very good now. All she had to do was forget that he was her husband.
