I was left to babysit my little sister. It wasn't bad, really, as there's always something to do at the lake. Megan was cute, though rather leggy, and pretty well behaved for an eight year old. Shiny light brown hair that hung to her shoulders to frame her round face, soft red lips that I'd kissed a couple times in fun, and large, emotional brown eyes. I think I liked her eyes most of all. I knew what she was feeling by just looking at those expressive eyes.

She'd smile and look up at me with those sparkling eyes and I turned to putty every time. But then there wasn't much I'd not let her do if she asked. I was wrapped around her fingers and we both knew it. Fourteen years old and already pussy whipped, but I didn't mind. With Megan, at least.

"Can we do something fun?" she asked with her sweetest smile. She found she could get anything she wanted from me with just a smile and a hug. And she knew it.

She wanted to go swimming, even more, she wanted to use my underwater air compressor with the hoses and full face masks. It seemed okay to me, we'd done it before, so I got it out and fueled it up, pumped up the float tube and started the motor. It floated on the surface pumping air down to us and I loved diving with it more than anything. My sister liked it a lot but we were only supposed to use it with my parents around. Like I said, if Megan wanted it, she smiled and I caved in every time.

We swam around underwater until we started to get chilled off and I pointed upwards. She swam up first to swim around under the dock, her favorite place to explore, and I couldn't help but notice how cute she really was in her suit. Hanging back a little I feasted my eyes on her tight little butt in her two piece, how her buns moved as she kicked with her feet, how the suit crept up between her legs to show the fat pads of her little pussy when she swam. I got hard right then and there.

Up on the dock I hugged her tight to warm her up then went to rubbing her soft skin briskly with a towel to make her feel warmer. She smiled sweetly as I rubbed her legs, even when I got close to her puffy, virgin treasure. My fingers brushed against the cloth-covered twin shells of her pussy as I moved from one thigh to another but she didn't seem to mind.

I did it again as I rubbed one leg, then again as I switched. She giggled each time I did it so it seemed like a good idea to touch it deliberately. Trembling a little I touched my fingers between her legs. My fingers gently rubbed her body through her suit, my eyes locked with hers. She looked a little confused and bewildered at the sensations she had to have going through her body, the first time anyone had touched her there.
