My sister and I started having sex when we still lived at home with our parents, the following is a story from back in those days. We are in our 20s now and still hook up but nowhere near as frequent as we use to. At home our rooms were 10 feet away from each other and our parents were out working a lot so we had plenty of opportunities to fuck and even fucked when our parents were home in the house.

When I was in high school I played football and one year I tore my meniscus in my knee and had to get surgery and wear a soft cast. I was taking showers in my parents bathroom during this time because they had a shower that had a built in seat in it and the bathroom I shared with my sister was a regular oval bath. One day when I came home from school I went upstairs to take my cast off to get in the shower and clean my leg from wearing a sweaty cast all day and my sister still wanted to fuck even though I couldn’t move much. Back then when we wanted to hook up she would approach me quietly and ask, or on days like this when it was just her and I home we just spoke it out loud and simply asked each other “Sex?” Or “Do it” and since I had surgery on my knee just days ago I figured we might take a break or something until I could walk and move around again, instead she stripped down to her bra snd panties and helped me clean my leg in the shower and after we got out helped me hobble from my parents room to my bedroom and laid me down on my bed.

We always made sure our house was locked and no one could possibly know what we were doing before we hooked up. Hell, we’ve had times where we were home alone and I asked her if she wanted to “do it”and we both were too lazy to do what was basically a security check on our house to make sure the coast was clear, either way, we did it every time because we’ve always been safe about what we do and never wanted to get caught. Anyway, she went back downstairs and made sure all the doors were locked and the curtains were shut and came back to my room completely naked. Whenever we had sex we almost always started with oral on each other but this time she came in and I was already stroking my dick in preparation for sex, and she just climbed on top of me and started riding me hard, so hard that it was actually starting to hurt my knee from her bouncing up and down on me. Fucking doggystyle is our favorite position and we really wanted to do it so she helped my up out of bed and I just stood behind her on one leg and fucked her from behind while she was bent over the bed. I fucked her hard and fast and tried to cum since I didn’t know how long I could go standing on one leg and it turned into a much longer sesh than I anticipated. I was able to fuck for quite some time despite being on one leg and as soon as I was ready to blow I just pushed deep inside her and she let out a moan I’ve never heard out of her before, I was so deep inside her and I held one hand on her shoulder so I could fuck her hard and she couldn’t shy away from the pounding. It was one of our best sessions to this day. Getting my sister off like that really made the sex special for me, she was completely untethered and raw with emotion and it was so hot knowing I gave her an intense orgasms on the daily. I loved having the scent of her pussy on me after we fucked, so much that I would wipe my hand on my dick and balls afterward throughout the night before showering again and just smell her pussy on me. It was so much fun being home alone with my sister during those days. We fucked even when my parents were home but we really got wild when it was just her and I home alone for a day or even a couple hours. We got home from school around 315-330 and our parents didn’t get home from work until after 5 so everyday during the school year if we both ended up coming home right away we almost always hooked up before our parents got home.
