Natalie avoided me for an entire day and, not surprisingly, I felt her distance keenly.
I struggled with my feelings. I had lusted after her for a long time now. It wasn't a passing phase. Maybe it was an infatuation. Probably was, in fact, but that didn't mean it couldn't be more. It had the deep, heart-twisting yearning of more. So, seeing her in such a private, intimate moment was incredibly erotic, and more importantly she had been thinking of me during it! I wanted to pursue a deeper, more sexual relationship with her, in secret, of course. The taboo nature made it all the more exciting. She was forbidden fruit—a sweet, succulent, juicy peach.
On the other hand, she was my step-sister. People would be horrified if they found out about my feelings toward Natalie, especially my parents. It just wasn't done. It was wrong. It was incest.
But was it, really? We weren't related by blood and hadn't lived together for long, and though I regularly dreamed of having sex with Natalie, I had no intention of impregnating her. Yes, I had been attracted to Natalie instantly, the first time I saw her through my bedroom window, but she was the one who came into my room the first night barely dressed. She started it! I was a slave to my hormones. In the end we were related to one another by ... what? A piece of paper in the county clerk's office. If not for that, we'd be total strangers.
I resolved to pursue her and maintain the secret. She was worth it. I'd make her understand.
Thursday afternoon rolled around. My father was off on another real estate excursion and Doris left for the grocery store. Soft music came from Natalie's room. I steeled myself, taking a long deep breath, and strode to her door. Time to be brave. I knocked lightly.
The pop music inside ended abruptly. Natalie opened the door and peered at me from underneath long lashes. We locked eyes and she bit her lip and stepped back to let me into her room. Sighing with relief, I entered. She shut the door behind me. Her hair was tied back in a pony-tail, and she wore no make-up. A white T-shirt flowed over her breasts and ended just before her waist, leaving a teasing strip of skin bare just below. A pair of tight pink shorts hugged her hips. Natalie had a thing for the color pink.
"We should talk," I said.
She nodded, but wouldn't make eye contact with me. She sat cross-legged on her bed, like she had so often on mine. Smooth, pale and freshly-shaved, her long legs and bare feet made me hard. I sat beside her on the bed, and nervously curled my fingers into my lap.
"I'm sorry I ... didn't mean to ... " I trailed off because it was a lie. A direct lie. I had meant to. She was the most beautiful girl I had ever known, she flirted with me on a daily basis, and I had stumbled upon her masturbating. Of course I had meant to watch.
"How much did you see?" she asked in a small voice.
"A lot of it. I don't know when you started."
She blushed and licked her lips before replying. "And you just watched me?"
"Yes."
"Why?"
I swallowed hard and tried to pretend I was brave. "At first I didn't want to embarrass you, and then ... well, you were so pretty and ... "
"Mostly naked."
"Yes."
"I didn't think anyone would be up at that hour."
"What were you doing in the living room anyway?" If she wanted to masturbate she could have just done what I had been doing for months. Lock the door to her room, and do it in peace without the worry of being caught.
"There was ... a show on." She giggled nervously. Yes, there was, and I had watched it. "One that made me want to touch myself."
Oh, she meant she was watching porn. Interesting. "You? Natalie, the perfect little good girl, watched porn?" It was pure flattery. I knew she wasn't a perfect little good girl. I liked her mischievous side, how she had depth to her, a depth I was just beginning to discover. I wanted to explore her. Not just her body, but her mind too.
"I'm not perfect, and I can be bad."
I grinned at her. "I bet you can." And I intended to thoroughly map that bad side.
Natalie slapped my shoulder playfully, but afterward she looked up with an arched eyebrow. "Did you tell anyone you saw me?"
My jaw dropped. Is that what she was worried about? "No, of course not. I'd never do that."
Her features relaxed. In fact, her whole body slumped. She hung her head again, a stray wisp of hair falling across her forehead. "Do you think I'm a freak?"
"For watching porn and touching yourself? No. We all do it. I do it."
A small smile played across Natalie's lips, she glanced down at my crotch, and it was my turn to blush. I had a full erection, barely hidden by my clasped hands.
"Did you like watching me?" she asked.
I cleared my throat. That was my opening. "Yes. I look at you sometimes and I wonder."
"What? What do you wonder?"
"What you look like naked," I said, honestly.
She flushed an even deeper red and turned her head away, smiling broadly. She liked that I thought about her that way. It was a relief. She could have been angry for crossing that line. "Well, you got an eye full."
"I'm sorry if I made you—"
"You peeped on me in a very private moment—"
"You were in the living room."
"At three in the morning." Her slim eyebrows narrowed. Even annoyed she was stunningly gorgeous. "Do you imagine me naked a lot? Like, when we do things together?"
"Yes."
She bit her lip and toyed with a stray lock of her hair. I could see the wheels spinning in her head, and I wondered if I should be scared. "I'm nothing special, Josh."
"You're special to me." That part wasn't flattery. One day of silence between us and I had been climbing the walls. Work had been hell because I couldn't concentrate. Everyone bugged me and I snapped at people. All of that after one lousy day. I had it bad for her.
Natalie continued curling her gossamer hair around her fingers, as she stared at me. Her smile was soft and warm, but I saw apprehension in her face. "I don't know what to say."
An awkward silence fell so I stood up. I had botched it and she probably wanted me to leave. When I looked down at her, sitting on her bed, barefoot, large innocent blue eyes watching me, her mouth parted a little as if she were breathless, I knew I couldn't leave things the way they were. I had to make a grand gesture.
I kneeled in front of her, between her legs. A brief image of me stroking her pussy with my tongue flashed in my mind. My imagination was far too active sometimes. My cock hardened to steel. I swallowed, trying to compose myself. "Would you accept an apology for watching you?"
"Yes," she muttered.
Go for it, I told myself, just do it. I rose and pushed myself toward her. She gave a little squeak and fell backward onto her bed. I followed, lying on to top of her, my chest pressing into her firm breasts. My erection rubbing up against the crotch of her shorts. Shock and surprise registered on her face, but also ... excitement. I leaned in and kissed her hard on the mouth. Slim arms wrapped around my neck, and one of her hands held the back of my head.
After a brief hesitation, she kissed me back and, unexpectedly, I felt her thighs lift and close against my hips as if we were fucking.
An eternity passed. I didn't want it to end, but like all good things, it did. I pulled back and away, dizzy with desire. "I'm sorry for watching you," I said. Another lie. I wasn't sorry. Not even a little.
She propped herself up on twin elbows, breathing deep and heavy, the blush still in her cheeks. Her legs remained wantonly spread. Her voice took on a husky tone I hadn't heard before. "Apology accepted, big brother."
I turned to go, and as I stepped into the hallway, ready to close the door behind me, Natalie called to me.
Peeking my head back into her room, I asked, "What?"
"Maybe I'll show you what I look like naked so you won't have to imagine it."

Coming around the last turn of the track, the finish line up ahead after a long straight-away, I tried to pass Natalie on the inside while staying on the course. My bumper made contact with her rear end and she spun out. I shot past, a video game opportunist to the very last.
She cursed when I zoomed over the black and white checkered line and took the flag.
"No fair," she whined. "I had that."
She sat on my bed in her usual nighttime attire. Nightshirt and panties. She had an exhibitionist streak a mile wide, and now that she was certain of my interest, she played it up. I didn't mind. More for me to ogle, but it was a delicate situation. She only dressed like this for me when our parents weren't around, and I wasn't allowed to touch.
At night when our parents were asleep in their room, their door closed, there was still the possibility of being caught with me. A nighttime foray to the fridge was not unheard of, as we both knew, but I think she liked the danger.
"I win," I said, grinning from ear to ear. I put my controller down, and lay back on the bed. My comforter was soft and pillowy, a steel gray cloud of cushion. Natalie seemed to like it too. I loved to watch her stretch out on it, her pale skin a perfect contrast.
Natalie grumbled. "Best five out of seven then. You cheated. Cheater."
