**********
I still remember the first time I noticed. We were on the beach, just relaxing in the sun, both of us lying face down. I had dozed off, and woke up and looked across at her and thought "wow, that is one damned fine ass."
Except there was a problem. That damned fine ass belonged to my sister, Alexis. Fortunately, Lex was also napping and wasn't aware that I was perving on her, but there she was, the same girl I had known my whole life. Every other day she had just been my older sister, but today I woke up and saw the sexiest thing I'd ever seen, sunning herself on the beach in a tantalizing bright orange bikini. I sat up, gazed around on the secluded, private beach, and then returned to mindlessly staring at her beautiful, tight little ass.
"Enjoying the view?"
I nearly jumped out of shorts.
"Huh?" Playing dumb was my only hope.
"The beach," she said, "it's gorgeous."
"Ah...yeah, it sure is." Somehow the fates had smiled upon me and the view down the beach beyond her was quite spectacular.
"Had enough sun for today?" I asked.
"Yeah, at least for now," she said. "What should we do next?"
"Let's head back to the cabin and get something for lunch," I said.
"Good idea."
We were staying at our family cabin in the lake country. When our parents divorced, they could only agree on two things - paying for my and Lex's educations, and keeping the cabin. Lex and I had been lucky enough to get a free weekend there right after the end of the semester in early June. I had just finished my freshman year. Alexis was two years ahead of me. We quite literally went separate ways after high school. She went east to a private college in New York. I went west to Oregon. Although we saw each other only at Christmas and during the summer break, we kept in touch by phone and followed each others lives on facebook and Twitter.
The cabin had been our family getaway for as long as we could remember, and we all loved the place. Our parents had managed to work out a sort of private timesharing arrangement so they could keep it after the divorce. The place was tucked into a cove with a small, private sandy beach, and the cabin itself was surrounded by towering Norway pines. During the day there was clean air and cool breezes. At night there were dark skies with countless stars.
My next shock of the day followed right after the first. Lex had untied her top so she could get some color on her back with no tan lines, and sat up without bothering to put it back on.
"Jesus, Lex!"
"What?" she said, as if it was just a normal everyday thing to go topless in front of your brother.
"Put your top back on!"
"Why?" she said, "it's totally private here. Nobody can see me."
"I can see you!"
"I guess you can," she said, "now stop staring and let's get our stuff."
With that, she turned around to gather her towel, her bikini top, and the few odds and ends she had brought. Bending down to pick up her things, she gave me another stunning view of the ass that had mesmerized me just moments before. She threw everything on her towel, picked up the works and started walking toward the cabin.
"You coming?" she asked.
"Ah...yeah, be right along," I said. I had to make an effort to focus, but I grabbed my towel and followed along, still hypnotized by the sway of her ass as she headed for the cabin. When we got there, she went to the bedroom to put her things away.
The cabin was small. Tiny might be a better word, with just one small bedroom. The kitchen and living and dining area were all one continuous room. I let Lex take the bedroom and I used the futon in the main room. There wasn't much privacy, but the setting more than made up for it. The cabin was on a small hill above the lake, and from the deck there were beautiful views. If I had been there with a girlfriend instead of with my sister, I might have called it romantic.
While Lex was in her room, I quickly changed out of my swim trunks and put on a pair of shorts. Just as I finished, Lex stepped out of her room, now in a right pair of booty shorts, and still topless.
"Alexis! What the fuck?"
"What?" she said, as if she didn't know why I was freaking out.
"Aren't you going to put on a shirt or something?"
"No," she said, bluntly. "It's just us in here. My roommates and I hang out topless in our rooms all the time. It's more comfortable."
"Apparently I'm going to the wrong school," I said.
"Really," she said. "Do your roommates always wear shirts in your room? Hell, you're not wearing a shirt now."
"That's totally different," I said, "we're guys."
"Oh, please," she said, "I'm just your dumb old sister, and they're just ordinary boobs, so chill."
"They may just be boobs," I said, "but they're not ordinary."
Oh, fuck, I thought. Did I really just say that out loud? I didn't know how I was going to get out of this mess. First I was staring at her ass, and now I just told her she had nice tits. Fuck.
"Thanks, Ian," she said, as if a guy commenting on his sisters rack was just another everyday thing.
"Sorry," I said, "I didn't mean to be commenting on them."
"Why should you be sorry?" she said. "It didn't bother me that you said my boobs were nice."
"Well, OK," I said, "but it's just not normal for a guy to be checking out and talking about his sister's body."
"Oh?" she asked, "it's the whole body now, is it?"
I couldn't believe it, but I had actually somehow just dug myself a deeper hole. Meanwhile, Lex struck a pose.
"How are my abs?"
Smokin' hot, I thought.
"My back?" she asked, twisting away to give me a view.
