Suami Sah di Siang Hari, Kekasih Gelap di Malam Hari

 Chapter 1

I've been spying on my step-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 step-sister , after all. To me it's just a good way to see some tits, ass and pussy on a regular basis.

My step-sister and I are like twins. We get along great, not like some brothers and step-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.

After our senior year in high school, right after I turned 20, we moved to San Diego and our dad shipped out for a six-month tour of duty aboard a destroyer. My mum died when I was 7 years old and dad remarried her mum and brought her daughter who was 6 years old to live in the house.

Her mum works as a paralegal, for a law firm downtown, so we are home by ourselves after school every day. This is our third house with a pool and that's where my step-sister and I spend most of our time.

I've noticed my step-sister 's body developing over the last couple of years, but I was not prepared for the feast my eyes got when my sexy, step-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 step-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 step-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 step-sister 's tanned tits two inches from my face. I desperately want to see them uncovered.

We finish in the pool and my step-sister goes into the house to change. My cock hCollinss 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.

Instead, I walk around the side of the house to my step-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 step-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 Lilly, I'm going in the pool. Want to go?" I ask my step-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 step-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.

My god! Her ass is spectacular. Her firm, young cheeks curve just enough to make you want to grab a handful and plant kisses all over them. Bent over like that, a few blonde pubic hairs and just a hint of her pussy lips are visible between her legs. I can't wait for her to turn around so I can see the rest of her.

But, instead, as I'm admiring her ass, she slips her swimsuit bottom over her feet and pulls it up. I get one last peek at her ass, before she grabs the elastic on the sides of her suit and pulls them down to cover her cute round cheeks. Hooking her swimsuit top, she turns it around so the hook is in the back and the cups are in the front.
