Shit! I better get in the pool fast. I've been so engrossed in watching her change that I didn't think about what would happen if she saw me coming around the side of the house and I wasn't even wet yet. Speaking of cumming around the side of the house; that was going to have to wait. I'm still hard as I hit the pool at a run and swim to the deep end, treading water, as she comes out of the house.

"How's the water?"

"Great, come on in!" I yell, hoping the cool water will relieve me of my uncomfortable, and obvious condition.

We stay in the pool for about an hour, fooling around like we usually do. If my sister notices anything different, in the way I'm acting or looking at her, she doesn't let on. I'm trying to act normal, but every time her tits get close to me, I can't help but think about her pink nipples sticking out from her firm young breasts. When she sits on the edge of the pool, dangling her legs and pushing the water sideways with her foot, I stare at the crotch of her swimsuit, imagining how her pussy looks. Fortunately, I don't have to imagine for very long.

When we're finished, I again make an excuse about checking the filter and run around to the side of the house. I wait a while and start getting nervous that maybe my sister is coming back outside. I'm just about to abandon my position when she walks into her bedroom with a towel wrapped around her. She's taken her wet swimsuit off in the bathroom and is now dropping the towel, as she closes her bedroom door. My eyes are glued to her pussy and what a sight! It isn't the first pussy I've ever seen, but the excitement of seeing my twin sister's pussy, makes my cock spring to life.

She has a nice v-shaped patch of blonde hair that almost covers her pussy lips, which are protruding slightly downward between her legs. I'm rubbing my cock like crazy and trying to take it all in...
