There were six of us in the pool; me, the two kids from next door, my sister, and two of her girlfriends, who were staying overnight before the three of them drove together for the start of their sophomore year in college the next day. Everyone seemed to be enjoying themselves, with a fair amount of splashing and raucousness. I found myself wistfully glancing over at my sister every chance I got.
She was outgoing and gregarious, while I had a more solitary, quiet disposition. So, even though I was eighteen and had just left high school, she still was able to get me to do what she wanted, just like she always had when we were younger.
You may recall me telling you about some of the things that had happened between us that summer. It seemed that, as the vacation drew to an end, she had distanced herself from me.
It was now a couple of weeks since she had let me touch her, and, although she still teased me with occasional glimpses of her body, she hardly paid me any attention.
There was just one bathroom on our side of the house, which we shared. She had insisted early on that summer that I not lock the door when I was in there.
This meant that she often barged in one me while I was shaving, brushing my teeth, or even showering or taking a piss. A lot of people would find this annoying, and think me quite lame for putting up with it, and perhaps they are right. But what they might not realize is that my sister was usually wearing the skimpiest garments when she came into the bathroom, and these would afforded me the most tantalizingly exquisite sights I had ever seen.
My sister was the first one to climb out of the pool, and I got out soon after. While she lingered outside, chatting to the others, I made my way to our bathroom, which, with its tiled floor, served as a good place to get out of wet swimming clothes, and change.
I grabbed a towel and had just started drying myself, when the door opened, and my sister walked in.
"Oh, I didn't realize you were in here," she said. She made no move to leave, but scooped up her long hair in a towel and set about kneading it dry.
I was running the towel down my legs, when I looked up to see her that she had dropped the towel and was able to undo her bikini top. I felt like there was an enormous pressure on my chest as watched her take the straps off her shoulders and let the garment drop away. I gazed at her breasts incredulous.
I had seen them before, but never had she exposed them to me so completely, so openly. She seemed oblivious, because the next moment she was hooking her thumbs into the waist band of the bikini bottoms.
With one quick movement, she had them down to her knees, and then, with a little cajoling, they fell to the floor.
She looked up at me.
"Aren't you going to get out of those wet swim shorts?" she asked.
I was trying to take my eyes off the hairless mound between her thighs, yearning to catch sight of the top of her slit before she went back to drying herself, obscuring my view.
By now I had a complete erection and I never knew what her reaction would be to my nakedness. I felt embarrassed to take them off, but just plain silly keeping them on, so I slowly slid them down, hoping my hard-on would subside in the process.
