The Cashmore house was quiet and tense all day Sunday; you could have cut the tension with a knife. Jennifer was perplexed; she didn't know whether to confront her mother, her brother, or just leave their dirty secret a dirty secret.
Michele could tell that something was bothering her daughter; Jennifer had been cold and remote ever since she and David had returned from their Saturday afternoon fuck-fest. Did she suspect? Did she know something? Michele was worried. She cornered David in the kitchen just after lunch.
"She knows David! She knows something!" Michele hissed.
"Settle down mom; she's just moody is all," David whispered.
"She's separated from her husband and cooped up here with us; no wonder she's batty; but why would she suspect anything?"
David stroked his mother's shoulder and, checking to make sure the door was closed, he kissed her quickly on the lips.
"Jesus David I wish she'd move out; this sneaking around is very unnerving," Michele sighed.
"But fun though," David slid his hand under his mothers skirt and stroked the front panel of her satin panties.
"Stop it you naughty boy," Michele giggled and squeezed the bulge in the front of her son's trousers; she traced the outline of his manhood through his denim jeans with a long red fingernail and then pushed him away.
"Not in the house!" she mouthed silently at him and turned on her heels for the door to the lounge room.
She flicked up the hem of her skirt giving David a quick peek at her red satin bikini panties; she smiled mischievously at him and then opened the door and stepped into the lounge.
David went up to his room and fired up his computer. He opened up the hidden 'MILF' folder. The folder contained a subfolder called 'MOM'; a new shaded subfolder now existed beside it. It read 'SIS'. David opened it up and opened the video file.
He watched the video footage he had secretly taken of his sister as she lay on his mother's bed. She was fully clothed but had pulled down her pantyhose and knickers and was fucking herself with her mother's vibrator. She pushed the vibrator inside her vagina and fucked herself with long slow strokes while she fingered her clitty with her free hand. She removed the throbbing vibrator and ran it over her clitty and screwed up her eyes as her orgasm shook her.
David opened the top drawer of his desk and removed the items he had stolen from the laundry basket earlier that day. It was the very same pair of panties still entangled in the sheer-to-the-waist pantyhose that his sister was wearing in the video.
David bought the flimsy garments to his face and inhaled his sister's scent. The aromas of her perfume and vaginal secretions assaulted his nose and he released his thickening penis from his flies and began to stroke it. He desperately wanted to wrap the knickers and hose around his cock and come in them but he was saving them for something special. Instead he reached into the drawer again and extracted a pair of his mother's stockings.
He draped the leg of a stocking over his penis and gasped as the diaphanous fabric slid over his glans. He tightened his grip and began to frantically pump his engorged organ, he was close to climax in seconds. The beige coloured nylon suddenly darkened as he ejaculated and his semen soaked into the stocking. The stain spread and gobbets of creamy ejaculate seeped through the sheer fabric and stuck to his fingers.
David groaned and inhaled the odours infused in his sister's panties as his orgasm washed over him. He stared at the video of his sister fucking herself with the vibrator and smiled wickedly. As he cleaned himself up, wiping his slowly subsiding erection with his mother's stocking, he thought about how he would execute his cunning plan.
His plan was bold. It was risky and could easily backfire but he had to confront his sister before she told anyone about he and his mother's illicit behaviour, or even worse, confronted his mother. David had not consulted his mother regarding his cunning plan and had certainly not confirmed her suspicions that Jennifer knew about their incestuous relationship.
David worked on his computer late into the night, stopping only for a quick dinner, and once again to masturbate; this time to video footage of him fucking his mother doggy style. She was fully clothed and he had hiked up her skirt, pulled down her knickers and pushed himself into the folds of her sopping cunt and fucked her until she screamed with excitement and ground her ample buttocks against his groin as she came; then he had pulled out and shot his load over her back and her arse-cheeks and thighs.
His spunk pooled on her skirt and ran in rivulets down her plump white buttocks and thighs and soaked into the welts of her stockings. His mother had chided him about coming over her good suit but he had caught her on his hidden camera the next day masturbating while she licked the crusty dried semen stains off her skirt.
Monday morning his mother and sister had left for work. David had dressed in his school uniform and made a pretext of preparing himself for another school week. When the house was vacant he went up to his bedroom and began to compose an email. He waited until nine thirty then he called Jennifer on the office phone where she was temping as a secretary. As soon as he heard her say hello he hung up.
Sure that his sister was at her desk he clicked the send button on the email and waited for a response.
The email read:
'Jennifer, I know you know. I also know about you! We need to talk. Come home for lunch; tell no one! Hope you like the attachments.
Love, David'
David had attached several screenshots of his sister lying her mother's bed fucking herself with her mother's dildo.
Jennifer paled and nearly fainted when she opened the email. She started to shake and had to gasp for air to get her breathing under control. She looked vigilantly around the office and confirmed that no one could see her computer screen in her small cramped cubicle. She opened the email attachments again.
"The little fuck!" she whispered.
It was obvious to her now that somehow David had somehow activated the hidden camera in their mother's bedroom. She was sure that the camera wasn't recording when she had sat down on her mother's bed, but somehow that bastard had activated the camera and filmed her masturbating with her mother's vibrator.
Maybe the camera was on a timer or had a motion sensor or something! The fact of the matter was; it didn't matter! Her brother now had evidence of her own indiscretions. Sure; it was not as dreadful as the evidence she had of her brother's incest but it was damning just the same. She was sure her brother was going to blackmail her with the video footage to make sure she that didn't tell anyone about his incestuous relationship with their mother!
She picked up her cigarettes and stomped out of the office after first locking her computer. She stalked up and down the outside smoking area puffing on one cigarette after another as she tried to figure out what she was going to do. She sat down on a bench and put her face into her hands and quietly sobbed. She pulled herself together and set her resolve. She would go home at lunchtime and confront the little weasel!
Jennifer looked up and saw that a middle-aged man in a business suit was sitting across from her staring intently at her legs. In her distressed state she had allowed her skirt to ride up and her legs to spread far enough apart to reveal the dark bands of her control-top pantyhose and her white satin panties under the dark nylon gusset. The man had an obvious erection tenting the front of his trousers.
"Here! Get a fucking eyeful you fucking perv!" Jennifer spat, spreading her legs wide and showing off the crotch of her panties under her control-tops.
