I’ve been spying on my sister for about two months; watching her change her clothes through her bedroom window. I never thought I’d take it any farther than just spying. She is my sister, after all. To me it’s just a good way to see some tits, ass and pussy on a regular basis.
My sister and I are twins. We get along great, not like some brothers and sisters. Our dad is in the Navy and we’ve never lived anywhere long enough to develop close friendships with other kids, so we’ve become each other’s best friend by default. We’re both pretty smart and have tested in the top percentile of our classes academically. We do just about everything together. We go to the movies, hang out at the mall, sometimes we even double date. I also think we have a special connection because we’re twins.
During our senior year in high school, right after we turned 18, we moved to San Diego and our dad shipped out for a six-month tour of duty aboard a destroyer. Mom works as a paralegal, for a law firm downtown, so we are home by ourselves after school every day. This is our first house with a pool and that’s where my sister and I spend most of our time.
I’ve noticed my sister’s body developing over the last couple of years, but I was not prepared for the feast my eyes got when my sexy, twin sister started spending most of her time in a skimpy swimsuit. She’s blossomed into a size 34B and the sexy curves of her tits, visible around the minimal material of her swimsuit top, captivate me. Her firm, young ass rounds out the bottoms of her swimsuit in a way that would make any guy look twice. Being around my sister, in our swimsuits every day, is getting to me. I find that I can’t keep my eyes, or my mind, off of her firm, young tits or her cute little ass.
We are playing in our backyard pool one afternoon, dunking each other and generally fooling around, when my sister climbs her way up my body and tries to dunk me. She seems oblivious to the amount of bare skin contact between us, but my cock certainly isn’t. I have to maneuver myself sideways so she won’t feel my hard-on.
Her swimsuit top is stretched tightly across her breasts and, when it gets wet, her nipples make pretty obvious bumps in the thin material. Pushing on my shoulders, she lifts herself out of the water, trying to dunk me. At 18 I’ve had a few girlfriends, but I’ve never seen a sight as sexy as my sister’s tanned tits two inches from my face. I desperately want to see them uncovered.
We finish in the pool and my sister goes in the house to change. My cock hardens as I 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.
