Hi everyone. I'm new to Literotica and this is my first story. I'd like to start by introducing myself - my name is Nikki, I'm twenty years old and I'm a south Indian from Delhi, currently in Kerala.
My sister, Anjali, was twenty-one at the time of this story, and I was eighteen. We lived a pretty normal life up to this point; our parents were at work all day, only coming home in the evening, and at the moment, and my sister and I studied at the same school. As siblings we were pretty close, and she knew all my secrets.
I was pretty innocent back then; on the day in question, which was the last day before the school holidays, we were walking home and witnessed two dogs having sex by the side of the road. I thought they were fighting at first and wanted to intervene, but my sister said to leave them alone as they were just playing. She had a strange blush on her face, so I knew that she wasn't telling me .
A quick look on Google when I got home told me what was actually going on, and after that my teenaged mind was full of questions about sex. Within minutes, my search began to bring up porn sites; of course, I couldn't resist watching some of the videos, and before long I was hooked. With the holidays now stretching before me, I was able to get up late and basically lie in bed all day and masturbate.
I thought I'd been pretty discreet about it, but one day after returning to my room after getting a snack, I noticed that my door was ajar and my computer was still logged into a porn site. I was sure I'd switched sites and shut my door; maybe I was just getting careless.
The following day, I awoke earlier than usual and, walking to the bathroom, I passed my sister's door. It was open slightly, and I heard some breathy sounds coming from her room. Pushing gently on the door, I peeped inside and saw her sat at her desk, her petite frame dressed only in her underwear. Holding my breath, and allowing myself a longer look, I noticed that she was watching a porn video; as her chair moved slightly, I could see that one hand was buried in her panties and the other was caressing her breasts. Her gaze shifted slightly, and I could tell that she had caught a glimpse of me in her mirror. She froze instantly.
After what felt like an eternity, she closed the laptop, stood up and walked towards me. Before I could speak, she placed a hand over my mouth. "I know you watch porn too, little brother. I checked your browser history, so don't pretend you're not doing this too."
I was paralysed by my nervousness, which only worsened as she looked down to check out the bulge in my pants.
"I'll make you a deal," she said. "If you don't tell our parents about this, I won't tell them what you get up to in your room every day, or that you got a boner from looking at your sister in her underwear."
I nodded my agreement, not knowing what else I could say, and left her alone to hide in the safety of my room. Now that it was obvious that she knew about my recently discovered daily masturbation habit, I didn't dare do anything. I was sure I could trust her; after all, we had kept each other's secrets all our lives, but this one was... much bigger.
What concerned me more was that I was beginning to see my sister less as a sibling and more as a desirable woman; I had now seen more of her amazing curves than I ever had before and I was captivated. I couldn't stop thinking about her, my mind conjuring up all sorts of unrealistic scenarios that I knew could never happen. We were brother and sister, and she would never see me in the way that I was now seeing her. I hid out in my room for the remainder of the day, only emerging when our parents came home and we had to sit at the table together to eat. I was virtually silent throughout the meal, staring at my plate the entire time and unable to look at Anjali in case she could somehow read my thoughts. I struggled to eat my food and left the table at the earliest opportunity, heading once more for the sanctuary of my room.
Sleep, however, was proving impossible as my thoughts of Anjali wouldn't stop and I daren't masturbate for fear of either her or our parents interrupting me. When it got late enough that I was pretty sure that everyone would be asleep, I decided to go and get a drink. To my shock, I got to the kitchen to find my sister there, clad only in a thin nightdress; I could see every inch of her shape through the fabric, which clung to her body. Her perky nipples stood out proudly as little points in the material, and as she turned to get a glass from the cupboard I got to enjoy the sight of the distinct outline of her ass.
