All characters in any sexual situations are over 18.
Some warnings: This is primarily a fetish story about a pissy, hairy, fat, sweaty old woman. It's a little long and becomes more than a little unhinged. The incest is secondary. There is exhibitionism, reluctance, and verbal degradation. In the end, it's all consensual. It's also a sweet old story of love and marriage.
-------------------
Michelle paid extra attention today, and Martin noticed with a thrill of expectation. His wife was often going for something out of the ordinary when she put this much focus on his cock, and usually this would lead to sex that he could only describe as spectacular.
She appeared to hesitate before she brought up a subject that she had broached a few times before.
"I'm thinking about Mom, honey."
This wasn't what you'd normally expect for foreplay, and it naturally threw Martin completely off. He wondered for a moment if it was a joke, but Michelle looked very serious.
"She's all alone since Dad died. After she lost the nursing job, she can't even afford to keep the house. She needs someone. I'm thinking about asking her to move in with us."
His wife was a perfectionist and a people pleaser who always tried to make everyone happy no matter how impossible. Martin loved her for this, but right now his alarms were going off. Was she trying to spring a trap on him for the first time in their six-year marriage?
Michelle was in fact setting him up for something, and she figured that with some luck the results would excite both him and her. Her plans were bold, unorthodox, and somewhat vague. They hinged on the fact that her mother was not quite a normal person -- or even a kind of person Martin would ever imagine. The whole situation would be difficult to explain. There could be misunderstandings. Actually, you could see a worried look on his face already. It would take some effort to reassure him that everything would be fine.
She climbed on top, which she did often to let him admire her body. He could never get enough of her body.
She was attractive in a youthful way even now in their early thirties. Her face was very pretty and innocent-looking, but it blushed whenever she was aroused, making her lips irresistibly red. Her breasts and hips filled his hands nicely, and she was developing some more curves lately. She wasn't very tall, and she sometimes complained that her height made her little pot belly pout out more than she would have wanted. Martin insisted with honesty that she was just becoming more perfect, and he only felt more excited for each year of growing older together with his curvy little cunt-bunny.
"Mom's coming over tomorrow, honey," she said now. "Mmhh, I was hoping to ask her already. Please consider it, honey! Oohhh, I promise I'll be an extra good little wifey for you if you do this for me."
The cunt between her legs had a mat of brown hair, which was more or less permanently wet with horny, smeared-out juices around her beefy fuck lips. Now, she aimed the bulging head of Martin's long and thick cock into the glistening slit and lowered herself.
His erection took over, standing stiff and ready for its daily baptism. He looked up and decided to enjoy the pleasures of that sexy body right now and think things through later.
"I promise there will be nothing to worry about honey," she said. "Ohh, we'll never have to be shy just because she's in the other room. Oohh, I promise to fuck you anytime you want me!"
To seal the deal, she leaned forward and let her breasts hang down, because he was always helpless in the face of tits. She teased him to take a stiff nipple into his mouth. He gave in, and she gasped out in approval and pleasure. When this tall, dark, and well-built stud sucked her nipples in oblivious ecstasy, she felt the way she imagined a goddess must feel.
The fuck-goddess sank her wet-haired and horny-sloppy fuck cave all the way to his root, squeezing herself in rocking movements up and down his entire petrified shaft, distracting him from any worries.
"Fuck, you're so hard!" Michelle cried out. "Aaahh, it's good! I'll still want your cock every day, honey! Mmhh, you'll always get to fuck me any time your cock is hard like this. Oohh, yeaahh!"
Their wet, humping, grinding mutual crotch pleasure grew more and more intense through over a minute of hard riding and thrusting.
He couldn't prevent himself from thinking about Michelle's mother. Claire wasn't your usual woman. She was so quiet, mousy, and overly polite that Martin didn't know what to think about having her around. He imagined the old woman in the other room right now, listening to their fucking. For some reason, his cock was beginning to tense up for a very early ejaculation inside his wife.
"Fuck, you're coming already, aren't you?" Michelle asked. "Oohhh, you're so hard! Mmhh, something turns you on! Mmmhh! Are you thinking about something kinky while you come inside me?"
He surrendered to the cunt-squeezes. She wrapped her arms around him in worshipping, loving ecstasy while he filled her with sperm.
The couple would both agree that their life together was perfect. Martin realized things probably wouldn't stay perfect forever, but he was hoping for a little more time. Michelle was hoping to take things to a whole new level.

It was the day of the move.
His mother-in-law wasn't someone he often thought of in a sexual way, but she stirred something inside him now when he was alone with her in a room, watching her pack her boxes for him to carry.
Claire was a gray-haired and very filled-out version of her daughter. Every time the 59-year-old woman bent over, her massive tits hung down and her wide ass-cushion stretched the dress. The garment was too tight, and it rumpled up to accentuate the fat around her stomach, which he didn't mind. He used to enjoy groping the soft, budding cushions around his wife's waist, and the folds of his mother-in-law's body were simply more of everything.
She seemed oblivious to his appreciation and kept apologizing.
"I hope I'm not too much trouble. You're so nice together, you and Michelle, and I would never want to make you uncomfortable in your own home."
She blushed, looking at him in a way that reminded him more of a schoolgirl than an old lady. He was well aware that his appearance could strike a nerve in some women, but he never thought the effect would extend to someone as old as Claire.
He was getting hornier every minute simply from standing close to her body. Her age didn't bother him in the slightest.
If there was even a single thing that bothered him, it might actually be her sturdy and clearly visible bra, which trapped those eye-catching breasts in an unnatural way. It reminded him more of chest armor than an accessory for comfort.
The words left his mouth before he thought them through.
"Speaking about uncomfortable, that bra looks a bit tight, Claire. Why do you wear it?"
He always did his best to treat people with respect. He knew already before the last word that this intrusive remark was out of line. He also realized that she would be the one to apologize. This woman was complaisant to a point where you felt safe to say almost anything around her.
"Oh dear!" she replied. "I'm sorry if it's offensive. It's just, they move around. But I never used to wear a bra, actually. Michelle's father wanted to touch, and I liked to keep him happy. He provided for me, after all."
She smiled with a dreaming look from the memory of her husband's touches. Then she returned to quiet shyness. Martin could understand his late father-in-law's desire to let this woman's spectacular bosom-bags dangle in freedom. It felt irrational to even have an opinion about something so private, but Martin wanted to enjoy the sight of some unrestrained jiggling in his own home as well.
His cock was swelling from the power dynamic he sensed to be developing between him and this subservient woman. She noticed his arousal. He was wearing soft jogging pants, which showed the semi-erection poking out.
"Oh dear!" she said again. "I hope I'm not causing discomfort. I don't want to be a disturbance in any way, Martin."
* * *
Even as he put her last bags down in the hallway of his house, the old woman kept insisting that she was only a guest there. She refused to be a burden. Her daughter and son-in-law shouldn't have to change a single habit.
Michelle demonstrated in a very direct way that she agreed. She embraced Martin and took his hand, putting it up to her breast. Their new houseguest flinched in surprise at this unexpected behavior, but she collected herself quickly and tried to act casual. Michelle encouraged her husband with subtle movements to grope her even more, and she let out an exhibitionistic gasp.
"Aahh, I promise, Mom, we won't change a thing because of you."
She gave her mother a lurid smile. Then, as if to demonstrate further, Michelle gave Martin a kiss with a little more passion and tongue than usual right there in front of the older woman.
There was something oddly aggressive about acting this way in front of an innocent old lady who was still in the process of moving in. Martin didn't understand exactly what was going between the two women, but he knew enough to stay out of it.
His long day wasn't over before he carried everything downstairs to a room they were fixing up for Claire. They didn't have a bed there yet. She would have to sleep in their huge 3-section sofa in the living room for now. She kept apologizing for the trouble, insisting that if she could do anything to help -- cook, clean, wash, shop -- all they had to do was mention it.
In the end, Martin was exhausted. For this first night, his wife helped him to clear his mind and sleep soundly by giving him a very vocal and passionate goodnight fuck.

"So what's our plans for today?" she asked him in the morning.
The couple were still in bed. They agreed that this was the day to take things easy, settling in.
