Thomas placed his hands in his pockets as he strolled along the trail beside Brian. His right hand made contact with the small piece of fabric left by his sister. Her panties. Still warm and slightly wet. He wanted to take them out and inhale her scent but could only imagine the reaction from his father. Brian himself was in a state. His eyes darting from his wife's ass to his daughters as they sashayed ahead of him. And then it happened. A strong gust of wind blew up both their skirts. Amy's bare bottom completely exposed, her white peach like, ample butt cheeks on display. Brian reasoned she must have been wearing a thong, the string buried deep within her crack. Jennifer's ass, marginally bigger, tanned and clad in a sexy pair of white lace french cut panties, leaving half her bum cheeks visible.
The moment lasted barely two seconds before each girl threw a hand back to press down her skirt and cover her ass but the wonderful image remained in Brian and Thomas's minds long after. Amy and Jennifer laughed, turning around to the confront the boys. "Get a good look?" Jennifer mused.
"Yeah, take a photo next time, it'll last longer!" Amy added, giggling, and Brian cursed himself for not having his finger on the shutter when it happened.
It was hot at the summit and Brian took a few landscape photos and using the timer, gathered the family to recreate a group shot from 10 years previous. When he was satisfied they all descended back to the car, happy to be out of the sun. Sitting in the back seat Amy had the desire to once again flash herself to Thomas but getting caught by her mother again, this time not wearing panties was too risky. She would have to be satisfied simply with the knowledge he was carrying her underwear. She placed a hand on the seat between then and was thrilled when Thomas in turn joined her, using his little finger to caress hers. It was intimate and sent a wave of emotion from her groin to her heart. She was falling in love with her brother.
At the turnoff to the lake, Amy and Thomas began to remember sights and sounds from their childhood. The gravel road and the towering redwoods. The smell of the forest. When the lake and the cabin came into view they both felt genuine nostalgia for the holidays spent there. "Oh wow, the jetty is still there!" Thomas exclaimed, remembering summer days running and jumping into the water from the small wooden pier. Now even smaller than in his memory.
"And the swings Thomas," Amy shrieked when their father pulled up outside the cabin. Jennifer and Brian smirked at each other in the front seat, delighted at the reaction from their children.
"We knew you'd enjoy yourselves up here if you gave it a chance, you always did!" Jennifer piped as they all exited the car and began unpacking.
"Hey don't count your eggs Mom, jury's still out." Thomas returned. "Hey, where's my bag?"
"It has to be there, are you sure you put it in?" Brian asked.
Thomas immediately realized he hadn't! He could see it sitting by the front door ready to go but Jennifer had asked him to put the cooler in the back of the car and he'd forgotten it. "Oh shit, I didn't! It's at home." Thomas declared.
"No big deal mate, there's probably still some clothes left from the last time you were here!" Brian added.
If it was meant to be a joke, Thomas wasn't laughing. He was 13 the last time he was at the cabin and was now double the size.
"Shit!" He again cried and helped unload the car.
Inside was much as Amy and Thomas remembered. Open plan kitchen and lounge room, two bedrooms and a bathroom. Their bunk beds looked so much smaller and Thomas didn't like the cracking of wood when he climbed upon the top. "That doesn't sound good!" said Brian. "You two might have to share the bottom bunk." Thomas and Amy looked at each other and tried to hide their smiles.
Thomas examined the leftover clothes in the dresser from previous holidays and discovered a pair of speedos. Taking them to the bathroom to try on he pulled out Amy's panties from his pocket, his penis began to swell just holding the item so he quickly replaced them. If he was going to try and squeeze into under-size bathers he didn't need an erection to make matters worse. Proudly attired in the swimwear, Thomas walked into the lounge to show the family. "OK, so how do I look?" He asked the crowd. His mother wolf whistled at the sight of his genitalia smuggled into the swimmers of a thirteen year old. Amy laughed but there was no malice and he smiled back at her. Brian reasoned that if college didn't work out, Thomas could get a job as a male stripper and he felt a little embarrassed when his mother stated she'd pay to see that.
After lunch Thomas and Brian were playing catch with baseball gloves they'd dredged up from the 'activities box' in the cabin. Amy sat on the bottom step watching them whilst eating a lemonade popsicle. She'd changed clothes, wearing a new white bikini and cut off denim shorts. She'd cut them herself and had possibly made them too short to be wearing around the city but here on holiday and for wearing over her bathers, it didn't seem too extreme. Not that her brother and father minded. Amy sat with her legs spread in order for her to not drip the rapidly melting icy treat. Her daisy dukes tight, highlighting the bulge of her mound at her crotch. The white of her bikini bottoms visible on either side of the denim.
Brian was first to drop the ball, concentrating more on his daughter than the game. Thomas fumbled next and an unspoken decision was made between the two to take a time out. Brian took up his seat in a prime position to admire his daughter and held his book at his groin to hide his growing erection.
Thomas went one better, sitting beside his sister and asking for a lick. Amy was happy to oblige, holding the popsicle out for her brother to taste. The lemonade ran down her arm and after Thomas had licked the ice, Amy licked the trickle from her elbow to her hand. Brian groaned.
Jennifer watched the spectacle from the window of their bedroom. "OK, so that's how it's going to go this weekend. Well Missy, two can play that game!" She walked to the wardrobe and inspected a number of swimsuits on clothes hangers. She had a few options she'd accumulated over the years for the cabin. Ranging from modest one-pieces to raunchy string bikinis. She chose a yellow bikini in a style from the 90's, small cups with a high waisted bottom. She hadn't worn it for years due to her weight gain but knew it would give the boys a show without being too overt.
Amy lay back on the steps, undoing the button on her shorts, "Mmm that was yummy," she said to her audience and Brian realizing the show was over, actually concentrated on his novel. For only moments though! The door to the cabin opened and Jennifer walked out wearing only her yellow bikini and carrying sunscreen. She walked between Amy and Thomas, rubbing his shaved head as she descended the stairs and lay down on a sun lounge beside Brian.
"Don't forget to pick up your jaw when we leave Thomas!" Amy sniped. He'd had probably the best view of his mother as she'd exited the cabin. Turned towards Amy he'd seen Jennifer open the door and become immediately mesmerized by her large breasts straining against the fabric. He'd been barely inches from his mothers crotch, her bikini bottoms slightly too small, hermetically sealed over her large pussy mound and struggling to enclose her magnificent rounded ass cheeks as she sauntered past him. Now spellbound by her lounging in the sun he could feel his penis swelling inside his speedos beneath his cargo shorts.
"Oh you're reading your book honey," Jennifer observed her husband. "I was going to get you to rub sunscreen on my back but you don't want to get it on the pages!" She looked back towards Thomas and Amy. "Well you've got that sticky lemonade all over your hands Amy so Thomas. You're up sweety! Come and rub sunscreen on Mommy's back would you darling?"
The look on Amy's face was incredulous as Thomas leaped at the opportunity. That bitch, she thought to herself good-naturedly. She's had the boys literally eating out of her hand moments before and now her mother had stolen the limelight. Thomas took the sunscreen from his mother as she turned onto her stomach. Squirting a liberal amount onto his hands he began on her shoulders. "Oh just a minute honey," Jennifer stated and reached around, undoing the knot on the back of her bikini and laying back down. "OK, go ahead Tommy."
Again Thomas returned to her shoulders, this time unencumbered by straps. He massaged the lotion into her skin accompanied by his mother's moans. Brian's focus no longer on his book, his erection returned as he watched his son innocently pleasuring his wife. Thomas moved down her spine to the top of her bikini bottoms, his finger tips encroached beneath the material then lathered her rib-cage brushing against his mother's side boob.
