Both Mom and my sister's excitement had been noticeably building all week. A weekend at a secluded beach house up the coast. Just the two couples; my parents, and Mia with her new boyfriend. They'd met through my father, a trusted colleague of his at the Institute, and three months in, it seemed their relationship was flourishing. Their first weekend away together, I'd overhead she was hoping to make it 'special.'
I didn't quite understand what THAT had meant, but the few shopping trips she'd taken mid-week with Mom had seen them both return home with bags full of new clothing, and I'd noticed some of them from noted lingerie retailers.
I had my own reasons to look forward to the weekend. A newly turned eighteen-year-old with the house to myself, I was planning on making use of the time alone. A raid of Dad's liquor cabinet on my schedule. A LOT of porn to watch. And even the phone number of the new girl that had moved in a few houses down the street. All going well, it'd be a weekend to remember.
It was just after lunch Friday afternoon, and taking it upon myself to clean up the dishes from said lunch, I was wrists deep in the sink when my sister squeezed my shoulders from behind and requested my attention.
"Which looks better?" She asked as I turned and wiped the suds from my hands. "The dress with these sandals..." She twirled for me, the already short floral dress rising up her thighs. "...or this?"
My breath was caught momentarily as she took hold of the hem of her dress and lifted it up her body, only to be relieved (or possibly disappointed) when she revealed an admittedly tiny pair of denim shorts beneath, a white bikini hugging her ample breasts. She kicked off the brown sandals and slipped her feet into a pair of flip-flops and once more spun to parade her outfit.
Though my older sister, I wasn't above ogling her impressive ass as it literally bulged out of the cut-off shorts and managed to not linger on the mound of pussy (with a hint of camel-toe I noted) as she trained her eyes expectantly upon me.
"Ah, why are you asking me?" I inquired, admittedly surprised she was seeking my perspective.
"Mom said to get a male's opinion," she flatly responded.
"I'm your brother."
"But you're still a guy. Come on, don't be weird about it. I want to look good for Toby," she looked down at her smart watch. "They'll be home soon, just tell me. Which is hotter?"
"Ah..." I could feel myself beginning to blush. "Just go with what you've got on."
The sound of Dad's car pulling up in the drive saved me from any further embarrassment and set Mia on her toes. "Thanks Lukey," she said as she turned tail with her sandals and ran from the kitchen. Admittedly I took another peek of her ass as she scampered away and was suitably impressed. Hey, as she said, I was 'still a guy.'
Dad called out for my mother when he finally entered the house and I heard them meet in the hallway. What happened then wasn't what any of us had expected.
"...but Jim, we're fully packed. All the food's already in the car," Mom was trying not to raise her voice and I strolled out into the hallway to partake in the conversation.
"I know Honey but it can't be put off, there's millions of dollars riding on this," Dad was attempting to explain something and I got a pretty good idea of what that might have been. The trip was off!
"Seriously, the whole weekend?" Mia was attempting to salvage the vacation. "Why does Toby have to be there? Can't he at least come?" She added, to which Dad scoffed.
"We can't just find a genetic particle physicist of his caliber at the drop of a hat," Dad countered almost laughing and really didn't read the room.
"This is bullshit! I'm calling him," she stated and marched off toward her bedroom. I didn't know what was wrong with me, but I watched her leave intently, my eyes firmly on that swaying bottom.
"What's going on?" I finally inquired now there was a lull in the conversation, and Mom turned towards me.
"The trip's cancelled," she conveyed what I'd already ascertained. "Your father's running some test at the facility and heaven forbid, he and Toby aren't there to oversee."
"It's not like that Darl," Dad tried to mitigate, turning to me. "It's the chromosome raiment synthesizer. They've brought the test forward a week. Everything we've worked towards is hinging on this."
"And it just happens to fall on this weekend. You know I don't think they'll even refund the beach house," Mom fired at Dad. "All the food we've bought..." Mom trailed off.
It looked like Dad finally understood how much disappointment he'd wrought on the family, (me included) and reached out to touch Mom's arm. "Well, the food will still get eaten and...well, why do you have to cancel the trip? You and Mia could still go," it was then he turned to me. "And what about Luke? You could go along. How does a free weekend at the beach sound?"
Admittedly, considering Dad would now be home with me, putting an end to most of my plans, it sounded pretty good, and I felt Mom's eyes train upon me. She still conveyed disappointment when I looked to her for guidance. "Are you still gonna go?"
It was then Mia slumped back along the hallway.
"It's final, weekend's off," she looked at her phone dismissively. "Toby says he has to be there."
"Your father thinks we should still go," Mom looked to Mia. "What do you think? Luke can come."
Mia shrugged and didn't seem enthusiastic either way. "Whatever, if y'all want."

An hour later and with a bag hastily packed I was sitting alongside Mom in the front seat as we drove up the highway. I turned to offer Mia sitting in the rear some chips and with her perched in the middle with feet either side of the drive-train, caught a sneaky peek up her skirt.
She hadn't gone with the denim shorts. An equally-as-tiny denim skirt the replacement for some reason, and as I'd noticed when we left the house and I helped her load her suitcase into the trunk, if she'd been trying to look 'hot' for her boyfriend, then with the skirt riding up so high on her thighs that I could see her panties peek out below, she should've gone with that to begin with.
The denim shorts were on Mom! But that's a story for later. Right then I was captivated by my sister's impromptu upskirt. With headphones over her ears, and her gaze captured by something out the window, I was free to look for slightly longer than expected, the previously spied white panties hugging her mound. I once more felt myself blush and the realization I probably needed a girlfriend woke me from my trance, managing to divert my eyes and get her attention with the snack and she took them gratefully.
Half an hour later and we had found the turnoff and after another twenty minutes along a sandy track, eventually pulled up at the beach house. The car unpacked and eager to get to the sand, I lost some of my enthusiasm when I looked at the stretch of empty coastline a shell's throw from the house. As I said, it was empty. Beautiful to be sure. But empty. My expectation was the opportunity to swim alongside other girls my own age. Admire some bodies of sunbathing beauties. There was no one else here. The entire length of the coastline, stretching for miles either way left to right was vacant. They didn't lie when they said 'secluded' on the website.
I headed back through the dunes to the house, relishing the cool lawn beneath my feet as it transitioned from the hot sand. Finding Mom on the deck, she was in the process of leaning into a hot tub to test the water and it was then I acknowledged my sister's shorts, now sitting around Mom's hips. If they'd been tight on my sister's admittedly healthy ass, they were like a second skin on my mother. I gazed at her bottom for a troublingly extended amount of time and came away with an equally as dubious impression. Mom had a great ass!
