Son You Know We Shouldn't Ch. 04

He ran his hands up the outside of her thighs and across the waistband at the top of her pantyhose and then began to slide a finger down the gossamer fabric slowly tracing the seam that ran down the middle of the pantyhose gusset.

"David!!!" Jennifer shouted; her eyes sprang open.

She looked down to see her brother intently staring at his finger as he slowly traced the raised pantyhose seam down her belly. She could feel the pressure of his finger through the layers of nylon and satin and it was quite arousing. Her pig of a husband had stopped being gentle and forgotten about foreplay a long time ago. On the scant few times they had sex; he just pushed himself inside her and ejaculated; providing of course he could even maintain an erection.

David's ministrations, although elicited through blackmail, were quite tender and erotic. But she had to stop him now or acknowledge that she was no longer being coerced and had become a willing participant.

She looked down again and saw David's engorged penis for the first time. It stood proudly protruding from his groin, long thick and hard. The skin of his shaft was pale and pulsing blue veins were visible beneath the translucent sheath; his glans was shiny, bulbous and purple-pink. A bead of transparent pre-seminal fluid seeped from the eye.

Jennifer unconsciously licked her lips.

"Brother; you know we shouldn't," she whispered, her voice husky.

David followed the pantyhose seam down to his sister's crotch and his finger slid between her legs into the warm silkiness of her crotch. Jennifer gasped and opened her stance to allow her brother access to her sex.

David caressed his sister's pubis through the layers of her underwear. Her pantyhose were loose around the crotch area and he began to stroke her mound. The nylon hose rubbed across her satin panties, the whisper of the diaphanous materials rasping together the only sound in the silent house other than the laboured breathing of brother and sister.

"Oh Christ David!" Jennifer moaned; she fell forward, supporting herself by putting her hands on her brother's shoulders.

Her skirt fell back down into place and she impatiently unzipped the side and let it fall around her ankles and then she kicked it aside and resumed her previous position; feet apart, knees bent, her pubis thrust forward lasciviously.

Little sparks of pleasure ran through her sex, ignited by the constant friction of her pantyhose gusset rubbing against her satin knickers. She bent her knees wantonly and opened up her thighs further, encouraging David to explore her cunt.

David felt the heat of his sister's cunt through the layers of slinky material and was rewarded with the first indication of dampness. He pushed his finger further into the layers of nylon and panty material and traced the outline of Jennifer's outer lips. She bucked against him and he pushed his finger in deeper until he could feel her labia, then he began to slowly stroke his sister's cunt occasionally twisting his finger so that his knuckle pressed against her clitoris.

Jennifer stood precariously balanced on her high-heels, her legs spread, bent at the knees as she rocked back and forth pushing her silken-clad pussy against her brother's fingers. She looked like a wanton whore; her lewd pose, her head thrown back, purring and meowing.

David twisted around on the swivel seat so that he was facing his sister; he put a hand around her waist and pulled her body to him until his head rested on her belly. Jennifer shucked forward until she was straddling her brother and sat down on lap. They were now face to face, she sitting on his lap her legs straddling his, his hand still buried in her crotch his fingers exploring her sex through her knickers and hose.

She looked into her brother's eyes and finally broke into a smile.

"You are a blackmailing little shit."

She leaned forward and kissed him; sliding her tongue inside his mouth.

"David, I'm old enough to be your mom," Jennifer said; her last attempt to diffuse the situation before it went beyond the point of no return.

"Yeah that's right; and you know what I'm doing to her!" David replied and drove a finger inside his sister forcing the material of her hose and panties inside her slick wet vagina.

Jennifer shuddered and wriggled on David's lap as ripples of intense pleasure radiated from her sex.

"Oh God David; let me take my pantyhose and knickers down," she gasped.

David held Jennifer down on his lap with his arm around her waist and entwined the fingers of his free hand in the gusset of her pantyhose and tore a hole in the crotch. He snaked his hand inside the hole, making it bigger, and then he slithered his fingers inside the sopping crotch of her satin panties and probed her labia. He flicked her clitty with his thumb and slid two fingers inside her hot wet vagina.

Jennifer drummed her heels on the floor as her arousal intensified. She pushed herself forward, her nylon-encased buttocks slid easily along her brother's thighs. Her crotch was only inches from her brother's hard cock and David's wrist was starting to cramp as his arm adjusted to the awkward position. He put his free hand under Jennifer's buttocks and tried to lift her; his intent was obvious, he wanted to lift his sister up and impale her on his cock.

Jennifer wriggled and scooted her arse a little further back towards his knees.

"David I'm not ready for that yet," she whispered.

David smiled. She'd said "yet!" That meant that she might be ready one day. He could wait; it had taken a little time to get to fuck his mother too.

He leaned forward and kissed her and she responded. Their tongues entwined as he explored her wet mouth with his tongue. She tasted of toothpaste, coffee and cigarettes; she smelled of 'Poison', bath soap and makeup, with an underlying scent of sweat and sex.

Jennifer was riding her brother's hand; he had two fingers buried inside her which he slid in and out in time with the thrumming of his thumb as it manipulated her clitoris. His mother had taught him well.

David desperately wanted to take off Jennifer's jacket and camisole and play with her tits but he was scared she might object as she had when he'd tried to fuck her. Jennifer was in the throes of passion, and although she wouldn't let him consummate their newfound incestuous relationship, he was enjoying their illicit sex play enormously.

His cock was throbbing; his sister hadn't touched it yet but it had fleetingly come into contact with her body on a number of occasions. She must know it was there; aching for release. He moved his hand and stroked her labia with his first and third fingers while he drove his middle finger deep inside her hot wet snatch and searched for her G-spot. He found it and she groaned and pounded her heels harder on the floor. He flicked her clitty and she began to pant into his mouth. He could taste her lipstick as it smeared over his mouth.

With his sister now totally engrossed in extracting from him every scintilla of pleasure she could, David decided it was time for him to start receiving some form of sexual gratification. He took his arm from around her waist and reached awkwardly behind himself into the top drawer of his desk. His fingers scrambled around until they found the articles he was looking for. He pulled them from the drawer and dropped them in his lap.

Jennifer was delightfully surprised at her brother's sexual aptitude; he was particularly adept considering he was only eighteen-year-old. Then she remembered the video footage she had seen of him having sex with their mother; Michele was obviously a very good teacher. She could feel her orgasm building slowly.

Jennifer typically took a long time to come; she had seldom reached orgasm with the boyfriends she'd had in her teens. One had been exceptionally good at cunnilingus and had bought her off every time they had sex but he turned out to be loser and she'd sent him packing. Instead she'd married her shit-head husband who at first had delighted in spending hours bringing her to climax with his fingers, tongue and cock but as their marriage soured he was content to bang her whenever the whim took him (which wasn't very often towards the end) with no interest in pleasuring her whatsoever.

Her climax was building; it started as a little bud of resonating pleasure deep in her vagina and began to intensify; slowly spreading through her entire body. Her engorged clitoris sent out intense little ripples of sexual delight every time David stroked it. She kissed him passionately to increase her stimulation; she was now a sexual animal concerned only with her own pleasure. Her own brother had unleashed her pent up sexual frustration and released a torrent of sexual vivacity that raged through her.

Something caught her eye at the periphery of her vision. She turned her head slightly and saw her reflection in full-length mirror fitted to David's wardrobe. What she saw reflected there inflamed her passion to greater heights.

An attractive mature woman sat astride a young man; her legs were spread wide straddling his lap. She supported her weight precariously on her high-heels as she writhed and wriggled in his lap. The boy was steadying the woman with his arm wrapped around her waist. She wore heavy makeup, her lipstick smeared around her mouth, her attractive face framed by a bob of jet-black hair. Her upper body was clad in a teal coloured blazer and a salmon pink camisole. Her lower body was naked except for the sheer taupe hosiery that sheathed her long legs; the darker control-top encased her thighs and buttock. Her satin panties were an ethereal white shape under her hose.

Her face was contorted in pleasure and her heels beat the floor occasionally when a particularly intense spasm of delight surged through her. Her well-formed, nylon-clad thighs glistened in the dim room; the boy in whose lap she sat had his hand buried in her crotch and was manipulating her sex through a hole he had torn in her hose. The boy's long thick cock rose rampantly from his crotch.

She turned her face back to David and saw that he too was looking at their reflection in the mirror.

She felt David's hand leave her waist and she was a little disappointed; but his other hand remained buried in her sex and continued with its practiced ministrations, inducing continuos waves of pleasure. She could feel him reach behind himself clumsily searching for something but she was too preoccupied with her own pleasure to pay too much attention.

David raised his hand to his shoulder and caught Jennifer's attention. She grudgingly pulled her lips from his and looked inquisitively at the objects he was holding in his hand. It took only a few seconds to for her to realise what her brother was holding up for her to see. It was a pair of panties entangled in a pair of sheer-to-the-waist pantyhose. Her panties! Her pantyhose! It was the underwear she had worn on Saturday; the day she had discovered her brother's dark secret and the day she had masturbated on her mother's bed with her mother's vibrator; the day her brother had secretly filmed her.

She'd expected to be angry; but she was surprised to find that she was actually flattered that David had kept her underwear as a trophy. She knew about his panty and nylons fetish of course; so it wasn't really a surprise that he had stolen them from the laundry basket.

She smiled mischievously.

"What do you want me to do with these?" she teased, knowing full well what her brother wanted.

"Please," David whispered; begging his sister.

He looked down beseechingly at his engorged penis and Jennifer giggled. She knew what her brother craved.

She took the diaphanous hosiery and slid a hand inside one of the legs; her ruby-red fingernail polish smouldered through the sheer nylon. She opened the leg of the hosiery with both hand sand lowered it to her brother's crotch.

David gasped as his sister draped the stocking over his swollen penis. She stretched and smoothed the diaphanous garment and pulled it tight. David's penis throbbed and a small globule of pre-seminal fluid leaked from the eye of his cock and soaked into the nylon. Jennifer stroked David's nylon swathed manhood; her long fingers flicked over the corona of his glans and stroked the frenulum.

"Mmmmm Yesss Sis," David gasped.

"But what about these David?" Jennifer dangled the red rayon panties in front of his face.

David increased the pressure on his sister's clitty and wriggled his fingers in her cunt. She pushed herself against him and sighed in response. Her orgasm would not be long in coming if David kept manipulating her like this.

"Mmmm maybe I should do this?" Jennifer teased and dangled the panties over his nose and mouth.

The scent of his sister's cuntal juices assaulted his nose as he inhaled the aromas secreted by the pretty red garment. He flicked out his tongue and licked at the crusty secretions caked in the crutch of the panties.

Jennifer was caressing and squeezing his cock, her strokes synchronised with his as he in turn masturbated her. They were both breathing heavy now, both close to coming.

Jennifer had one more trick left before she bought her brother to climax.

"Or maybe I should do this?" she giggled.

She pulled the stocking taut over his thick pulsing shaft and tied the pantyhose in bow around the base of his shaft. She let the other leg and the waistband of the pantyhose flutter around his scrotum. She caressed his sac briefly and felt his testes retract, ready to discharge in a pulsing torrent the reservoir of semen stored inside him.

Jennifer lifted up the panties so that David could see what she was about to do. She spread them wide and then draped the seat of the silky garment over his pantyhose sheathed cock.

David groaned and felt his orgasm building.

"Oh God Sis wank me; please wank me!" David begged and thrust his fingers deeper into her sopping cunt and frantically stroked her throbbing clitty.

Jennifer fell forward and smashed her lips against his and drove her tongue into his mouth. She gripped her brother's cock and began to milk it; sliding the panties up and down his cock in long slow strokes. The slick panty material rasped against the nylon stocking that she had swathed tightly around his cock and ignited sparks of intense delight.

David came.

He bucked up and down in the chair as his penis pulsed and flooded the panties that his sister had wrapped around his cock. A spurt of hot semen erupted through the nylon stocking and shot into the air landing on his sister, scalding her wrist. A second spurt landed on her thigh; the white gobbet of semen pooled on the coffee-coloured nylon and began to slowly soak into her pantyhose.

Jennifer felt her brother's cock jerk and throb in her hand and then she felt his scalding semen splash over her wrist and splatter on her thigh. She kissed him with renewed fervour.

Jennifer came.

She howled with passion and locked her lips on her brother's mouth and sucked on his tongue as she writhed in his lap; her high-heels beat a staccato rhythm on the bedroom floor. David thrust his fingers in and out of his sister's sopping cunt and frantically manipulated her clitoris.

Brother and sister clung to each other in orgasmic bliss. They writhed and clutched and stroked and pawed at one and other, each sibling milking an earth-shattering orgasm from the other.

After a minute or two, when their respective orgasms began to subside, David and Jennifer broke their kiss so that they could catch their breath. Jennifer wriggled a final time in David's lap as the last skerrick of her orgasm pulsed from her cunt. Her pubic hair was matted with her juices; her labia were distended and a little sore. She felt sated, her vagina felt a little bruised, but in nice way. She scooted her buttocks back a little, signalling to David to remove his hand from her tender pussy.

David slowly removed his hand from his sister's sex.

Jennifer felt David's cock stop pulsating and then it began to slowly deflate. She wiped up the final dribbles of semen with her come-soaked panties and untied the pantyhose she had wrapped around his penis. She dabbed at the pools of semen on her thighs, wrists and fingers and flung the garments aside.

"I suppose I've lost those forever now," she smiled.

"And the ones you're wearing," David grinned back at his sister.

Jennifer steadied herself and stood; a small flood of vaginal secretions gushed into her panties. She picked up her skirt and flicked it a couple of times to get the wrinkles out.

"Fuck! Look at the time!" she exclaimed looking alarmingly at her watch.

"David I have to get back to work! I'm late!"

"We need to talk about this. I'm still not sure exactly how I feel about it; but we need to talk," she said.

"And get rid of that fucking link off your computer you blackmailing little shit-head!" She slapped him playfully across the ear.

David watched as she strode out of his bedroom still holding her skirt; her long sleek legs and her firm arse looked fantastic encased in the control-top pantyhose. His flaccid penis began to thicken.

Jennifer went into the bathroom and kicked off her heels; she pulled down her pantyhose and panties and kicked them off. She washed her sex with a damp cloth and went back to her room where she fixed her makeup, stepped into fresh panties and hose and pulled on her skirt; she sprayed herself liberally with perfume. She stepped back into her heels and, after a final adjustment of the hem of her skirt; she clattered down the hall anxious to get back to work.

As she passed David's bedroom she threw her ripped pantyhose and pussy-juice soaked knickers at David who was still sitting down at his computer.

"Present!" she called out as she strutted down the hall and down the stairs.

"We need to talk! Tonight!" she called out and closed the front door behind her.

On the drive back to work, a thousand thoughts and suppositions bounced around her head. She wasn't sure how she was going to deal with this development. One thing she did know though; her aching pussy hadn't felt this good in years.

Back at the house David was hard again; this time he was wanking into the control-top pantyhose his sister had been wearing this afternoon and sucking on the red rayon panties she had wanked him with.

He was watching his latest video.

On the computer screen his sister sat in his lap facing him; she was fully-clothed but skirt-less and she howled as an orgasm wracked her body.
