On a brutally hot August day, Shirley was sunning herself on the rented houseboat's sun deck. Her head rested on her folded arms, her legs spread, and her body gleamed with sweat. The gusset of her bikini bottom split her meaty labia.
Shirley was determined to get some sun, something she rarely did at home. She wasn't proud of her fleshy body and usually hid it under muumuus. She thought she looked like a beached whale with yards of soft white skin.
She had no illusions about dieting or spending hours in a smelly gym. At 52 years old, with a penchant for rich desserts, she earned the extra pounds she carried in her jiggly ass, soft mom belly, and large breasts.
Shirley slipped off the sheer wrap that covered her bikini. The suit was little more than three strategically placed triangles of sheer cloth held together by strings of dental floss. The tiny bikini was out of character for her. She bought it for this trip, rationalizing that she could expose more of the body since there would be only the three of them.
Her son Austin sat on a padded bench on the stern of the houseboat. From this vantage point, he stared between his mother's legs, desperately trying not to touch his painfully hard cock. He was 19 years old with hormones raging through his body like water in a river rapid.
Lately, he has become interested in his mother's soft mommy body. He often fantasized about sex with her, and seeing her like this, almost naked, was more than he could stand. He almost lost it when she reached between her legs and pulled the bikini gusset from between her pussy lips.
Shirley was aware that her 19-year-old son was well into puberty and was fascinated with the female form. Lately, he showed more interest in her body. She often caught him staring at her.
Initially, it was disturbing, and she was concerned she had given birth to a pervert. Some Internet searches, the modern source for child-rearing information, educated her.
Boys in puberty, like her son, develop a fascination with their mothers. She was the first and most influential female figure in their lives. The rush of hormones caused them to confuse maternal love for sexual love. One article said that the king in Oedipus Rex unconsciously knew it was his father he killed and that the queen he took was his mother. He was living out the fantasy of sex with his mother.
With that knowledge, Shirley accepted her son's voyeurism as evidence of a boy with a healthy interest in sex. She began to enjoy his attention. Her sex life with her husband of 25 years was mainly in the rearview mirror. When they did have sex, it was usually because they toked and got high.
Shirley was perimenopausal. She went through cycles that ranged from Sahara-like vaginal dryness to volcanic heat. The night sweats and hot flashes were distracting, and her emotions were all over the map. Her gynaecologist prescribed a Hormone Replacement Therapy (HRT) patch. She warned her that the flood of hormones would be unsettling initially, with periods of sexual arousal, but her body would adapt.
She took another sip of her wine. It was her third glass of the day. Between that and the several puffs of marijuana she secretly had, she felt light, airy, and more than a little horny. She hoped she and Carl could have sex later. It was nearly three weeks since the last time. After 25 years of marriage, sex was infrequent.
I had better get some suntan lotion on, she thought. Else I'll burn to a crisp.
Shirley was of Irish extraction as her fiery red hair, fair skin, and a smattering of freckles attested. She was prone to burn rather than tan. Her husband, a light-skinned Creole, tanned to a deep chocolate brown with no danger of burning. Their son was like his father in that respect.
She squirted some oily lotion in her hands and began applying it. As her hands spread the oil, she knew that Austin covertly ogled her.
She made a fateful decision. Later she would wonder about her impulsiveness. She rationalized that stumbling across internet sites extolling incest while she did her research on pubescent boys conditioned her mind to the unthinkable.
"Austin, come rub suntan lotion on my back."
Austin jumped when his mother spoke, lost as he was in his favourite fantasy world of sex with his mother. The reverie consumed him. He thought she was the most beautiful, sexiest woman he knew.
At 19, his pantheon of mature women was limited, but that did not constrict his fantasy. Still a virgin, he masturbated to images of her nightly. He routinely clothes hamper dived for soil panties, adding an aromatic component to his fantasies. Now his goddess was asking him to touch her. The very thought had his cock rigid inside his board shorts.
"Aw, mom! Can't dad do it?"
He did not want to seem too eager. At the same time, he was frightened at the prospect. He was already leaking precum. Touching his mother might cause an eruption like he sometimes had at night when he dreamed about his mother.
"Austin! Do as your mother say!"
His father's muffled voice wafted up from the wheelhouse where he piloted the houseboat.
Carl Favreau was intent on steering the unfamiliar craft. The instructions back at the landing were thorough, but piloting a houseboat was new. It required all of his concentration to apply the lessons the rental agent gave to the actuality.
Besides, the last thing he wanted was to apply lotion to his wife's body. He loved her dearly. However, after three children, she was not the voluptuous beauty of their youth.
He conceded they both had put on a few extra pounds. Unconsciously he sucked in the gut earned by years of beer drinking and binge eating brought on by their penchant for marijuana.
They were children of the '60s, and marijuana was Carl and Shirley's recreational drug. They strove mightily to keep their use of it from their children. They were partially successful. Their children knew of their use but never confronted them about it and were amused that their parents felt the need to conceal it.
Toking made Carl sleepy and Shirley horny, an explosive combination for a woman at the end of her childbearing years and concerned about her sexuality. The HRT patch caused Shirley to experience explosions of intense sexuality as her hormones ran rampant.
Shirley was also kinky, with a penchant for D/s and BDSM back in the day. Her husband indulged her but was uncomfortable with the erotic scenarios she envisaged.
Shirley watched her son stand and move toward her. He slouched, trying to keep his hands in front of his crotch. Her eyes widened in surprise and amusement as she realized he had a hard-on. She stared at the significant bulge, smiled, and rolled to her belly.
At least I can excite SOME male animal, even if it is my son, she thought.
Carl had not gotten that hard in eons! She reached behind her and untied the bikini's top.
"Be sure to get my back and legs. They don't see much sun and are prone to sunburn."
"Yes, ma'am!"
Austin eyed the substantial bulge of his mother's breasts on the sides of her body. His hamper exploration told him she was 38DD. He knew she had big nipples because they created large indentations in her thin cotton nightgowns.
Austin eyeballed between her ass cheeks that the material created as Shirley's bikini bottom stretched across her behind and disappeared between her legs. There was a significant bulge between her legs where the cloth covered her womanhood.
"Hurry up, Austin! Else I'll spend the rest of this trip sunburned!"
The wine, reefer, and the slow roll of the houseboat relaxed her. Shirley drifted off into a twilight zone where she dreamed of being tied up and ravaged by hardbody men with big cocks. These fantasy men were insatiable, fucking her repeatedly until her pussy overflowed with cum.
She was dimly aware that her son's hands seemed to spend more time on her sides, occasionally bumping the mound of her breasts. Austin's hands roaming her body enhanced her fantasy. She pressed her Mons into the towel and slowly rotated her hips.
His mother's seeming acquiescent emboldened Austin. His hands slipped up her sides and across her protruding breasts. His cock throbbed when he slowed and lightly squeezed the sides of his mother's breasts.
He applied suntan lotion down her back to just above her large bubble butt, down the back of her legs, and back up the sides. He leaned closer on each round trip until his tumescent tool brushed against her behind as he applied the oil.
In her twilight state, Shirley reviled in the male hands caressing her body. As Austin's hands moved across the sides of her breasts, she was tempted to raise to allow him access to her nipples. It would be so naughty. Naughty was what she needed to reassure her of her womanhood. The changes in her body made her think she was less than a woman.
Austin's hard cock lying between the cheeks of her ass brought her out of her reverie. Her son was dry humping her as her hips rotated, pressing her Mons into the towel! The relaxed state created by the drug and alcohol suppressed her outrage.
It felt good, and she let it go on for a while. She resisted the urge to raise her ass and increase the pressure. It would be so naughty.
