I came downstairs in my usual morning attire, shorts and a loose T-shirt, to find that breakfast was being held out on the patio. You could always tell when a summer day would be too hot for grilling dinner in our house because Dad would fire up the grill in the morning instead and make us pancakes and sausages out in the morning sun. They never turned out as evenly cooked as the griddle inside, but that was part of the charm.
Alexis yawned her way out of the patio door and slumped down on the chair next to me, leaning against my shoulder to continue snoozing. Her stunning breakfast outfit was not too dissimilar from mine, though she wore a cropped tanktop that showed off her shoulders and belly and her shorts ended just below her ass cheeks instead of mid-thigh like mine. Dad set a plate of fresh hot pancakes and sausages in front of us and my sister and I each took half the stack.
The sun climbed far enough to start baking the back lawn as we slowly nibbled away at breakfast and Mom suggested we go to the pool to avoid having to run the AC at full blast all day. Dad declined because he'd planned on clearing out some of the junk that was piling up in the garage, but he wished the rest of us a fun time and promised not to touch the thermostat until the sun was going down.
I didn't have anything else to do. I'd already registered for all my college classes and ordered my books. Freshman year was probably going to be hectic when it arrived, so I might as well relax for the month and change I had until then. If Alexis had anything else to do, it wasn't happening today. Mom gave us fifteen minutes to get changed, get our stuff, and be in the car.
Twenty minutes later, we were walking across the parking lot to the pool entrance. We could already hear the sounds of splashing and smell the chlorine tang in the warm air before we got inside. Mom showed our neighborhood membership and we skipped the locker rooms, heading straight out to the pool deck. The sun had reached just the right height that it made the light colored concrete of the deck almost blinding.
Thankfully, it wasn't too crowded yet and we spied a set of three chaise lounges next to each other near the deep end. Mom dropped her bag on the first one and pulled her shirt off in one smooth motion, revealing her mature body barely covered by her dark green bikini. She pulled a bottle of sun tan oil from her bag and immediately started oiling herself up.
Alexis took the middle lounger and stripped out of her shirt as well, but she had also elected to wear a pair of shorts over her bikini bottom and lost first oil privileges. I took the last seat and stuffed my shirt away in my bag while we waited for the oil. Mom handed it off and stretched herself out to toast, pulling a book and her sunglasses from her bag in one motion.
I watched Alexis rubbing oil on herself through squinted eyes. Both she and Mom already had a bit of a tan going over the past month of summer, but they'd finished last summer several shades darker than they were now. While I waited for my turn with the bottle, I couldn't help noticing how the oil on Alexis' skin made the hint of muscle on her slender arms and belly really pop.
Watching her oily stomach glisten in the sun, I almost missed her thrusting the bottle at me before she lay down on her lounger and slipped on her own sunglasses. I looked away in case she was watching me behind her shades and oiled myself up, then I dropped the bottle back in Mom's bag and lay down to soak up some rays myself.
The next thing I knew, I was hearing Mom's phone alarm beeping and realized I'd dozed off. She was apparently startled by it too as she dropped her book while trying to fish her phone from her bag.
"Oh, shoot. I forgot Ellen was supposed to come over today. She's coming all the way across town and now the house is going to be an oven." Mom said, bopping herself on the forehead with her phone. "I need to get back there asap and get things ready."
Alexis groaned. "I was just about to go in the pool too." She got up and started to pull her clothes back out of her bag.
"It's not that long of a walk home, sis. I'll keep you company." I said, sitting up.
Mom already had her bag slung over her shoulder. She hadn't even bothered putting her shirt back on.
"But I didn't bring any shoes, just some old socks to cross the parking lot." She was already pulling the ratty things back over her feet.
I reached into my bag and checked to make sure my other sandals were still there. I held them up in front of her face and then dropped them beside the sandals I wore on the ride over. "I got spares. Pick whichever you like when we're ready to leave and I'll take the other pair."
She gave me a fist bump and then scrambled up after Mom who was already half way back to the entrance. "Wait, Mom! You've got the tanning oil!" Alexis hurried back, stuffing the bottle into her own bag before sitting down to undress her feet again. "Time for a dip. You coming in?"
"Nah, go ahead. I like the pool atmosphere, but the chlorine makes my skin feel gross."
"Suit yourself." Alexis shrugged and plopped her bag on her lounger.
I sat up a bit and watched my sister mount the closest diving board and stand on its edge, contemplating the water below. She was wearing a mismatched bikini as usual: A sporty red top that she said she liked because it made her tits look bigger, and a black bottom that wasn't quite a thong cut, but close to it. Even at the short distance to the end of the diving board, it almost looked like she was bottomless from the way her shapely butt cheeks stuck out around the back piece of her suit.
She leapt into and under the water, so I let my attention drift away to the rest of the pool patrons. There were quite a few more than when we arrived and I gave a thumbs up to a scantily clad lady who asked if she could take the lounger Mom had vacated. She had to be close to Mom's age, but she looked more like Alexis and it was a pleasure to watch her sexy hips wiggle as she carried off the pool chair.
My attention was drawn back to the pool when I heard a splash and I turned to see Alexis fling a leg up on the edge to hoist herself out. She could have taken the ladder on the far side, but naturally her way was easier. The maneuver did make the skimpy nature of her bikini bottom extremely obvious and pulled in my gaze like a magnet.
She tugged on her bikini to readjust the fit and walked back over to her lounger. Right as she was about to sit down, one of the staff unlocked and opened the maintenance hut right behind us. Apparently it was aggressively air conditioned as a torrent of frigid air wafted straight across us. It passed me over rather quickly and the cooling effect it had was quickly reversed by the sun, but it had a very different effect on my sister, fresh out of the cool water and coated with a slick film of moisture.
"Aw, fuck that's freezing." She shook with a sudden chill, her skin dimpled with goosebumps all over and her nipples looked like they were about to poke right through her top. It was hard to tell under the dark fabric, but I thought her bikini bottom shrunk or tightened a little from the cold and put a bit of a camel toe on display.
She rubbed her shoulders and hugged her arms across her chest for a moment, swaying on the spot before she reached down and hooked the handle of her bag, lifting it and extracting the bottle of tanning oil.
I kept watching her as she reapplied the oil to her upper body, finding it difficult to look away. My eyes kept straying back to the dark black void of her bikini bottom, hoping that each small movement might cast light on some little detail showing through the fabric. I quickly flicked my eyes away when she once again thrust the bottle in my direction.
"I don't want to bend over, my knees are still shaky. Do my legs, please?" She'd asked me to oil her back a number of times before and she'd done the same for me, but she'd always done everything else herself.
I sat up and took the bottle, unable to refuse my sister's request. My hands shook a little as I squeezed some oil out, but if she noticed, she didn't say anything as I laid my hands around her left knee. She really was still shivering just a little and her skin was cold to the touch, but my hands cut through that chill and let the sun warm her back up to the air temperature.
I spread the oil down her calves first, my hands gliding over and warming her skin as the coconut scent of the oil started to waft up in the heat. As soon as the goosebumps were banished, I could feel how smooth Alexis kept her legs. Just a bare hint of stubble here or there where some spot had started to grow back quicker than the rest.
Giving a quick brush of oil over the tops of her feet, I flicked my eyes back up past her knees. Alexis was standing still with her legs slightly apart, right where she was when she handed me the bottle. She'd put her sunglasses back on and had her face turned directly at the brightest part of the sky like a sunflower. I took it as a sign that when she said legs, she meant her thighs too.
As I gave it a fresh squeeze, the coconut scent of the oil was a bit stronger from the bottle heating in the sun. I reached out slowly and placed one hand on each of her thighs, right above the knee. Her skin had been slowly warming in the sun and air, but it was still just cool to the touch for a moment until my hands imparted their heat.
