Part 1:
It was the 3rd day of her well-deserved vacation and after 2 days of sleep and pampering, Blair was getting restless in her bed.
She rose languidly and made her way to the balcony, it was almost noon and she was alone in the house. Her husband William left for work some time ago and won't be home for quite a few hours.
As she stepped out into the warm sun from her cool bedroom, she feels the heat on her skin and breathes in the warm air filling her lungs she stretches like a cat in the sun feeling her body come alive in the heat.
She just takes in the silence of mid-morning, no traffic, no neighbors, just pure silence.
As Blair takes a seat to lounge in the sun for a few minutes, something catches her eye that drives the little bit of sleepiness still in her.
The neighbors had trimmed the trees a few days ago and now she had a straight line of sight into their walled pool, And what a sight it was. They were fucking right there on the lounge chair.
She was right opposite them and couldn't see their faces but she got a good view of a firm ass plowing into the girl whose legs were held over his shoulders.
Blair stepped back and settled into a chair so she wouldn't be spotted. Her eyes riveted on them, Something about watching them fuck and that was the only work for it, there was nothing gentle, nothing nice, he was fucking her and Blair didn't need to look at their faces to know that they wouldn't stop until they were spent.
Blair watched as the girl brought her legs down, around him and pulled the man into herself pushing him in deeper. And then she heard it the first sound the low pitched keening of a woman trying to control herself as she's orgasming, she watched as the man's back tense and relax she knew he came inside her, Coating her inside with his warm cum.
Blair watched as he stood as the woman opened her legs releasing him and as he stood he pulled the girl up with him and pulled her in for a kiss. She got the first clear look at them. It was the twins Jessica and Asa her neighbor's children.
She watched as Asa dip one hand into his sister's cunt and as he brought it up Jessica devoured his fingers lick it clean and they continued their incestuous kiss tasting themselves.
She smiled to herself as she thought that, they were 21 only 5 years younger than her and she knew Jessica quite well, All the stories they swapped and she never suspected Jessica was this kinky. That little cum slut.
As she watched the twins gather their discarded clothes and towels and head back into their house the gears were turning in her head.

Part 2:
It was almost 3, and Blair was finished prepping.
She picked up her phone and called Asa.
"Hi, Asa. It's me, Blair."
On the other side of the fence, Lying in bed besides his sister, Asa answered the phone.
"Hello, Blair. Do you need to talk to Jessica?"
"No, I actually called to talk to you."
"Me!"
"Can you come over for a minute?"
"Now? I mean aren't you at work?"
"I'm on vacation, We got a week off as bonus."
Asa kept a light hearted tone but his mind was screaming 'The Trees, The fucking Trees. She knows, She saw us.'
"Oh, Sure. Give me a minute."
He cut the line and looked at his sleeping sister, He didn't want to worry her when he wasn't even sure that they were caught, He disentangled himself from his sister slowly so she wouldn't wake up, got dressed and headed out.
The door opened before he finished knocking, and what he was left him speechless.
Blair stood in the doorway her black hair pulled over one shoulder, in a long white silk robe sash loosely tied, giving Asa a peek at the red lace corset. She took a step back drawing his eyes to her legs clad in red stockings.
"Come in, Asa." Blair exclaimed. Reaching one taking him by the arm, "Don't be shy. Don't mind my dress I usually don't dress up when I'm home alone."
Asa his arm now trapped firmly in Blair's pressing into her breasts stammered a response. His head was spinning, This was not what he expected, he got a great deal of practice with his sister they never practiced seduction.
And Blair blabbered on as she lead him through the house and to the deck, Asa went with her nodding his head, he could barely concentrate on her words.
Blair sat him down on a wooden chair on the deck and took a seat opposite him in the sofa, She ran a hand over herself and as Asa watched she undid the sash opening the robe and letting the robe hang free. And she waited in silence.
Asa was now thoroughly aroused and confused, He tried not to look at her directly, he was a guest and she was married but couldn't help himself from looking at her, he saw the her legs rubbing against each other and saw that she was wearing garters not stocking.
He tried to move his chair back and was surprised at how heavy it was, he looked at the table which has a cloth covering some things, He looked at her and saw her corset matched the garters, With a neckline so deep it was obvious she was shaven.
Blair too watched him and it took Asa a few minutes of silence to recognised her demeanor, he released she was putting on a show, for him.
He began to relax a bit and asked "You wanted to talk to me?"
"Yes." Blair smiled, "I wanted to congratulate you. That was quite a show you put on today."
Blair kept the smile on her face but she was overjoyed inside as she watched the blood drain from his face. So far everything was going as planned.
"No need to be shy, Asa. We are all adults here."
Asa nodded and replied shakily "Thank you."
Blair stretched out on the sofa and lifted her legs, Asa moved back in his chair to avoid her legs she placed her feet on the edge of his chair in between his legs, her stocking clad toes lightly brushing his crotch. His cock already hard flexed at that brush.
Blair's smile was now a cheshire cat's grin. "Your girlfriend is a very lucky girl Asa."
"Girlfriend ... " he mused.
"Unfortunately I missed most of the show." Blair was now tracing her toes over his cock through his shorts and his cock was responding rising and falling in a pronounced bulge.
Asa thought 'She doesnt know. She didn't recognise Jessica.' and with that realization his fear turned into confidence.
"How long have you 2 been seeing each other?" Blair continued.
"Not that long." Jessica was waiting for him back home but here was a beautiful, mature woman, seducing him and now no longer afraid Asa now going to take full advantage of it. "Is't Willam home yet." He asked with a smile of his own.
"He won't be home for some time yet." Blair answered. "That's mainly why I called you here."
"Ho."
"Yes, Think you're up for an encore?"
"Absolutely, But my friend already left, And it's a 2 person act."
"Maybe. I can fill in her role? With some slight modification."
Asa his eyes on her "Won't Willam mind?"
William won't mind at all, but there's no need for Asa to know that just as there's no need for him to know that Blair knows who his 'Girlfriend' is.
"What william doesn't know won't hurt him. Now strip. And come over here."
Asa tore away his shorts and his shirt and stood up nude, his cock free and erect, Blair still on the sofa reached out and delicately stroked it. Pulling his closer until it was a few inches from her face.
