In the Pool

I was out in the pool just trying to cool off,kind of floating around when my sister came out and took a quick dip.She got out and sat on the deck and started reading one of her teen magazines.I wasn't really paying any attention to her until she asked me some kind of question and when I looked at her I noticed that the crotch of her suit had pulled over to the side and I could see almost all of her pussy.

Being thirteen at the time and seeing my first real pussy instantly got me hard.I moved over to the side of the pool to get a better look trying to act calm about it and talking at the same time.I don't think she had any idea what she was showing because she didn't make any attempt to change positions.As we talked she kept her eyes on the magazine so she didn't see how hard I was starring at her.

Having found the joys of jerking off just a few months before I took the chance that she wouldn't get up and slowly pushed my suit down until my cock was free.Then trying to act as calm as I could I jerked off while talking to her.It sure didn't take long before I started to cum and even after I finished I was still hard so I did it again,this time taking a little longer.I was just starting on number three when she started to get up and I quickly pulled my suit back were it belonged.Good thing because she came right over to the side of the pool where I was.Her suit was still pulled over to the side so I got one more good look before she went into the house.

That was the only time anything like that ever happened but I still think about it every once in awhile when I'm jerking off.
