Sex Story of the Week : "Brother-Sister Have Unexpected Sex"

My sister and I decided to live together to share expenses because neither one of us were married yet, and we both needed to save money.

We ended up getting a tiny house in the country, which was very quiet. I guess the place was a little too small for an adult brother-sister roommate situation, but we thought we could make it work.

One day I thought she was in her room and I was naked. Since you could hear any noises inside the house no matter what room you were in, I decided to go out back and masturbate because I was so horny I didn't know what else to do.

I was just about to ejaculate when I heard my sister say, "Can I watch?" This kind of scared me at first, but I finally said OK. So, she stood in front of me and ripped off her clothes. Even though I had temporarily lost my erection from being interrupted, I felt like I was ready to shot my load immediately as soon as I saw a real nude women standing in front of me.

Then she said, "Why don't you put that big thing inside me?" I didn't need much time to again have a huge boner and she was on the ground with legs spread. We had sex three times that afternoon. She had semen and vaginal juices running all over the place, so I just helped her out by smearing it all over her (as we laughed). Then she took a shower.

The next few days were quite awkward as we both felt a little guilty about doing what we did without even considering the possibility of her getting pregnant. I was nervous for weeks, until she told me she had her period. That meant she was most likely not pregnant.

She found a boyfriend about two months after our experience. It was kind of like a relief for me; because I wasn't sure I wanted sex to happen again with my sister. Nevertheless, I must admit I think about that one-time sexual experience with my sister when I am masturbating.
