My sister and I started hooking up a long time ago when we were in high school still living at home with our parents. During the first summer we started hooking up we would fuck 5-7 times a week. We lived in the suburbs outside a major city and our parents worked 9-5 Monday to Friday jobs in the city so they would leave for work around 7-730am and not be home until 5pm so my sister and I had the place to ourselves all day. I’ve always been an early bird even as a kid, I was always up early as hell so I’d stay quiet in my room and pretend to be asleep just waiting for my parents to leave. As soon as they did I went outside and smoked a joint, came back inside and made sure all the curtains were closed and all the doors were locked to be safe, and as soon as my sister woke up an hour or two later, she came in my room and get in my bed, we go down on each other and fuck doggystyle all morning then just walk around our house naked until we felt like showering and getting dressed, sometimes we would fuck in my room, then a few hours later be watching tv downstairs in the living room together and we’d fuck some more on our couch. It was fucking amazing every day. We got so much experience with each other and as we got more comfortable we would just talk about what we wanted to try sexually like positions and toys, and we just experimented on each like lab rats all morning before we showered and got dressed and went out with out separate friend groups. I miss those days so fucking much! Some days I was lucky enough to fuck my sister in the morning then go out all day with friends and end up hooking up with a girl at a party or just some girl I’ve been talking to and fuck two girls in one day. Damn I really miss those day!
