Chapter Text
My sister and I are VERY different people. She’s bubbly and outgoing. I’m introverted and a wallflower. She’s constantly down to hang out and go to parties. I was always the one being dragged along, either by her or my friends. She was a boy crazy attention whore, and I was actively struggling to come to terms with the fact that I was both agnostic and a lesbian after being raised loosely (holiday) catholic. Despite all this we have always been very close.
We’re close to 2 years apart, but in school we were only one grade apart, so we ran in a lot of the same social circles. So that definitely helped. It also helped that when our mom got remarried, we suddenly had to share a room again to accommodate the fact that we now have 6 people in a 3-bedroom house (our parents, brother and our new sister).
One night shortly after I had my first time with a girl when I was 15 or 16, I was laying in bed trying to sleep. I’ve struggled with that since I was a little one. Never could just drift off. After a while, a light clicked on in the dark room. I didn’t turn to look because I recognized it as a cellphone screen just from the color and amount of light. I figured she was just reading a text or something. So I shut my eyes again and tried to sleep. After a few minutes, the light didn’t go off.
I opened my eyes and tried to see what she was doing. I didn’t move or say anything, still in that half relaxed state. But I noticed the blanket on the bed moving. She was reading something on her phone, way too far away to tell what, but she was definitely reading something and slowly moving her hand between her legs.
My breath caught in my throat and I tried not to make a single sound. I could hear her breathing, not heavy, not yet at least but heavier than she does at rest. I watched the rise and fall of her blankets and tried to make out the details of her face in the glow of the phone screen.
It felt like an hour passed, but it was probably about 5 minutes when I realized not only was I wet, but I was rubbing myself too. I don’t know how long I had been doing it but when I noticed I slid them to the side and started rubbing myself directly. Slowly her breathing got heavier and very occasionally I could hear the smallest little whimper or caught breath escape her lips.
After a few more minutes she threw off the blanket. Unfortunately she was still under a sheet AND the only light was her iPhone so I couldn’t see anything at all. But quickly I noticed I could hear her fingers working over her soft little folds. I closed my eyes and focused on the sound, I rubbed myself wishing I would taste her, lick her fingers clean at the very least, but at that moment I wanted nothing more than to feast on my little sister.
I’d always thought she was beautiful but even when we’d changed together I’d never thought about her like this. Admiration yes, always, but never arousal. Never a need. The more I heard the slick wet sounds in the silence of the room the more I prayed she couldn’t hear my own.
A bit later I was treated to a heavenly sound, the softest sweetest moan of my little sister as she failed to hold in her orgasm. I can still hear it a decade later haunting my most taboo dreams. I almost came at the same time and had to slow down so I wouldn’t be caught.
