I seduced my sister when she was alone

My sister Emma and I have been intimate for the past four months, and I want to share how it all began, the moments that sparked it. One day, I was home alone, reading some taboo stories online. It was around 2 or 3 in the afternoon. Mom had gone to visit our uncle, and Dad was working in Germany. That evening, I got word that Mom would be staying at our uncle’s place overnight. Emma, my sister, isn’t exactly curvy but has a fuller figure, with a well-proportioned body and stunning legs. She came home around 3 p.m. I got up from the computer and headed to the bathroom to shower.

When I came out, I froze. Emma was at the computer, reading the stories I’d left open. I’d never felt so embarrassed. She was still in her school uniform—a gray skirt, black tights, and the skirt was shorter than usual, barely covering her thighs. It caught my eye; she’d never worn it that short before. I walked over, quickly closed the stories, and noticed she was blushing too. I begged her not to tell anyone, and she agreed, saying, “It’ll stay between us.” I told her Mom wouldn’t be home tonight, and she grinned, saying, “Guess we’re free then!” I told her to leave my room so I could keep reading, but she teased, “Let me stay and read too.” I refused, and she went to her room.

About an hour later, I stepped out and saw she still hadn’t changed out of her school uniform. I told her to put on something else, but she said she was too lazy. Then, with a mischievous smirk, she said, “You like schoolgirls, don’t you?” I was stunned—how did she know? Then I remembered the pictures saved on my computer. She must’ve seen them. “Your computer’s full of them,” she said, confirming my suspicion. I stammered, trying to change the subject, but her skirt had ridden up on the couch, revealing her gorgeous legs. She didn’t mind me staring, and it was clear she was teasing me. My heart raced, but fear held me back.

She suggested we read the stories together. Hesitantly, I agreed. We sat at the computer, and as we read, she “accidentally” dropped her pen under the desk, asking me to grab it. When I bent down, she parted her legs, giving me a breathtaking view—her legs glowing through her black tights. “You read, I’m comfy down here,” I said, almost hypnotized by her beauty. I started kissing her knees, then moved up, despite her playful protests. She was clearly trying to drive me wild. I asked if I could touch her legs, and she agreed, “Just a little.” I caressed her thighs, and she teased me further, crossing her legs to flash me more.

She glanced at my obvious arousal and laughed, calling me desperate. I shot back that no guy could resist this, and we both laughed, the tension easing. “I’ll keep dressing like this all evening,” she teased, and I jokingly said she was trying to kill me. We grew comfortable, openly talking about sex and intimacy. I suggested watching an adult film later, and she agreed.

That evening, we watched the movie together. Her skirt was hiked up so high it barely existed, and her tights were driving me crazy. I caught her touching herself briefly, and when our eyes met, she pulled her hand away. I offered to pleasure her, and though she was curious, she asked how. “Leave it to me,” I said. I had her sit on the couch and started kissing her feet, working my way up, savoring her tights. I tore a hole in them and pushed her panties aside. She was freshly shaved and slightly wet. I began pleasuring her, and she pressed my head closer, moaning that it felt amazing. I brought her to climax.

Then it was her turn. I told her to mimic the movie, and she took me in her mouth, focusing on the tip at first. I urged her to take more, and when I warned her I was close, she hesitated but let me finish in her mouth, swallowing everything. I noticed her shirt was still buttoned up, so I undid it, revealing her small but perfect breasts, glistening with sweat. I kissed and nibbled them, driving us both wild.

I went back to pleasuring her, exploring every inch, even teasing her backdoor. She was nervous, so I used some olive oil to ease things, but she was in too much pain, and I stopped, scared of hurting her. She suggested her front instead, admitting she was a virgin but saying it was okay. She made me promise I wouldn’t marry until she found a husband, and I agreed. I positioned her on her back and entered her slowly in missionary. She cried out as I took her virginity, an overwhelming feeling for both of us. I couldn’t hold back and finished inside her multiple times.

Since that day, we’ve been intimate regularly, always with her in her school uniform, which she loves as much as I do. Her legs and breasts are unforgettable, and writing this now brings it all back, stirring me up again.
