Rob came home from school a little earlier than expected this afternoon. I guess it was just too beautiful a day for him to spend another hour studying frogs in biology. I had my closet door open and was using the full length mirror inside the closet to check out one of my new swim suits. When he walked by my room, I was looking over my shoulder at my ass in the mirror which caused me to stick out my ass in the most provocative way. From the door to my room, Rob had the greatest view. "Checking yourself out, Sis?" he taunted.
After I settled down from his startling hello, I looked at him and suddenly had an idea. "What's the look for?" he asked.
"Do you have the ability to be mature about something?" Oh no! He started to leave. I keep forgetting how much he hates being reminded that I'm 13 months older. "No, wait! Sorry about that. It's just that this could be embarrassing. I'm going to the beach tomorrow and I want to look good. I was wondering if you could give me a guy's opinion on some of my new suits?" I showed him the bag of new swim wear I had just bought.
"Sure, if you want. Who're ya trying to impress?"
"Never mind...just take a seat," and I motioned to my swivel desk chair.
After he sat down and spun around to face me, I did a little twirl and said, "This is the first one."
"If you really want my opinion, you'll have to go a little slower." The first one was a wet-look tank-suit with high cut hips. It still covered a decent amount of my butt (depending, I guess, on your definition of decent).
The top was a pretty low scoop-cut and showed the tops of my breasts nicely.
"How's this?" I replied and put my hands behind my neck, pointing my elbows to the ceiling. In that position I gave him a very slow turn with an occasional swaying of my hips. I think he almost lost it right then, I heard him clear his throat and saw him sit up straight to pay more attention.
"Well?" I said to break the silence.
"Uh...very nice. You look great. I don't have anything to compare it to yet, but very nice."
"Ok then, turn around." I saw the shock in his eyes that I wasn't asking him to leave while I changed. He obediently turned around, though, probably didn't want to risk my changing my mind! Little did he know that I had a plan all laid out for him this afternoon. I had left my closet door open just right so that he could see me in the full-length mirror behind the door. I pretended not to notice the door, the mirror, or his stare as I slowly undressed.
First I reached for the silver strap over one shoulder and pulled it down, exposing one perfect breast fully to his view. Then I repeated this motion with the other side and in a second or two I dropped the suit to the floor.
This wasn't the first time Rob had seen me naked, he had been barging in on my showers for years for one made-up reason or another. But somehow this was different and my body responded to the thoughts I was having of purposely stripping for my brother.
I lingered there naked for a moment and held up the next suit, also a one piece. Then I began to put it on. When I had finished, I told him to turn around. "This one's a little different. The sides are adjustable like this," and I hooked my fingers in the sides by my hips and pulled up. "I can leave the sides down and look respectable or I can tie them up like this and go daring." With that I pulled the strings and tied the suit up above my hips.
I couldn't wait to spin in this one because judging by what was left covered in front (not much), he was going to love the back. The top of this one also had straps over the shoulders, but plunged down in front below my breasts and just was tacked together every few inches.
"Is Mom going to let you wear something like that?" he asked. Just as he asked I lifted my arms again and went into my slow spin again.
"She doesn't even have to know. Right?"
"Not from me...not if I get a show like this once in a while!" Then I was halfway around and he was looking at my ass, barely covered, "Wow, that looks great!" Then I stopped and lowered my hands to my hips, sticking my ass out a little more as I turned my head to look at myself over my shoulder.
"You know," I said, "this one can be real naughty back there. Tell me if this is too much." Then I reached down and stuck my fingers a little inside the fabric and, while pulling up, I fed the fabric into my butt. This left my butt totally exposed to him with just my crack filled with the fabric.
"Oh my god, Lynn! You can't be serious? Would you really wear it like that?"
"Well, probably not, I just thought you'd appreciate the style since you were enjoying my butt! I didn't know you enjoyed butts so much! I thought you were always staring at breasts."
"I like every aspect of the female body, but you've got a great ass. Well, I definitely like this suit better, but you can't wear it like that out in public, just leave a little covered or you'll be causing accidents!"
"Ok, turn around again. One more one-piece, then two bikini's." When he turned around, I noticed out of the side of my eye (in the mirror) that he had to adjust "himself"-apparently his jeans were getting tighter. Then, he looked up and was once again treated to the show in the mirror. The next suit was all white and almost see-through because I had cut out the liners from the breast, crotch and backsides. It, too, had little ties at the hip for adjustability, but only had little strings over the shoulder tying behind my neck. "All done."
When I turned back around, Rob must have noticed just how see-through the suit really was because he was staring at my breasts. There was no missing the dark circles of my nipples showing through. I was still adjusting my 'hip-strings' to a provocative-but-still-decent level as he studied my breasts and erect nipples. He didn't notice me look up at him as I was finishing. "Do they look that good?" I asked as I then cupped a breast in each hand.
"Oh...uh...sorry...you're the one that asked me to check you out." He then had to cross his legs because his manhood was definitely responding to my holding my breasts like that.
"Don't apologize, I didn't say I was mad or anything. I just saw you staring and its actually kinda a compliment. I guess you do like breasts after all!
Ready?" Then I raised my arms and got into my starting pose.
"Yup." My twirl got slower each time and I definitely was making the motions sexier as I stuck my ass out towards him and swayed my hips. As I turned, I noticed myself in the mirror and saw how thin this material was without the liner because I could definitely make out my ass crack inside the suit and as I came around, there was a darkening at my crotch. I'm not sure what was turning me on more, the sight of myself being so sexy in the mirror or the knowledge that my brother was completely turned on by me. I was moving towards auto-pilot with hormones increasingly taking over. Then I asked for his opinion and he almost choked clearing his throat again.
"It's fantastic, but you can't be thinking of wearing it to the beach are you?" When I nodded, he continued, "It's practically see through now, which I don't mind-you are the sexiest thing I've ever seen-but if you get wet, there'll be nothing left to the imagination!"
