watch her tight ass wiggle across the patio toward the sliding glass door. I can't believe how badly I want to see her naked body. I tell her I'm going to check the filtration system and will be right in.

Instead, I walk around the side of the house to my sister's bedroom window. This side of our house has a covered walkway with lots of bushes. I position myself to see in her window, without her or our nosy neighbors seeing me. I look for an opening in her blinds so I can watch her change, but the way the blinds are positioned, I can only see the ceiling. I give up (for that day) and go in to change.

The next day while my sister is watching TV in the family room, I sneak into her room and adjust her blinds, leaving about an inch and a half gap between the bottom of the blind and the windowsill. After changing into my swimsuit, I head out toward the pool.

"Hey Lisa, I'm going in the pool. Want to go?" I ask my sister casually as I walk through the family room and out the sliding glass door.

"Sure, I'll be there in a sec," she says, getting up from the couch and turning off the TV.

That's my cue. Around the house I go. I get to her window just in time to see her entering her bedroom. She is pulling her shirt up as she closes the door. I stand there mesmerized, as she tosses the shirt on her bed and begins taking off her bra. My cock jumps, creating a bulge in my swimsuit, when I get my first look at her teen sized mounds. I stare at them, enraptured by her inch and a half areolas and little pink nipples. But the real treat is watching her unzip her shorts and slide them down her tan legs.

My sister is average height, with a flat stomach, and a body that curves in all the right places. She turns from the window while taking her shorts off and I'm looking at her panty-clad ass, as she bends over. I start rubbing my cock through my swimsuit, to relieve some of the pressure, as she hooks her thumbs in the waistband of her panties and slides them down.
