Catching My Brother

My brother is 3 years younger than me so he's 18 but we've spent loads of time when we were younger and some of them have always seemed weird to me. I was always a swim girl and whenever my family came to meets to watch me I could never shake the feeling he was eyeing me, but it is a swim meet so what else would you look at you know. I've also caught him checking me out even when I'm not wearing anything provacative like jeans or something. Things got a but weirder as we got older and I started meeting guys and doing stuff. One time I brought a guy home with me and we snuck him in through my window. We were making out in my bed and things got a little heated to where I started grinding against cock against my clit until we both came. It was the middle of the night and we I got up to get some stuff from the bathroom to cleanup. I noticed my brother was in there and I thought I could hear him jerking off. So I went downstairs to grab some stuff to cleanup instead. Another time was when I would sext some people online through discord. One day I was doing homework on my laptop then my dad called me to go pick him up because he had some car problems. I know I left my laptop in a certain way open on my homework. When I got back I noticed my discord was open but it was running in the back. I looked in it and noticed it was on the messages between a guy and I. I think he looked through the messages and stole my nudes I had sent the guy. All these things happened when we live together and I moved out a while ago. I've always been thinking about teasing him. Maybe showing him a photo I have by accident, telling him a story of a guy and I, telling him something about his slutty sister. Maybe I'll tell him I knew about everything he's done and I touch myself to it. I think he may be a cuck because of how much he's tried to look into my sex life, so maybe I'll show him some photos and feel up his cock a little. I don't think he ever knows just how much I love teasing guys.
