My sister and I have always been close. My dad walked out on us and our mom when we were just 5 and 3 so I had to help her with certain aspects of growing up. High school was fun and I tried to teach her as much as I could about what guys were after. She was growing up fast and there was nothing I could do about it.
When she went away to college we kept in touch. She was only an hour away so it wasn't all bad. After her freshman year she told me she didn't like it there and wanted to transfer to another school- out of state and clear across the country. Needless to say I was disappointed. See, somewhere between her junior year in high school and now she turned into a drop dead gorgeous woman.
I came home one Friday night a little bit earlier than normal. I knew my mom would be asleep and thought my sister was out with friends. The house was dark and rather serene.
As I walked down the hall I heard a noise coming from my sister's room. I walked toward her room and the closer I got, the noise was no longer a noise- it was a moan. A low, sensual moan.
Her door wasn't closed all the way so I crept closer to investigate. I peeked in and could not believe what I saw. My sister was naked from the waist down and was busily playing with her pussy. An absolutely amazing sight. Her light next to her bed was on low so it made it even sexier to look at.
I grew hard at the sight of my baby sister playing with herself. I instinctively dropped my hand to my crotch and started to rub the outside of my pants. I wanted so bad to take out my cock and jerk off while watching her, but I was afraid she would hear and stop and then I would have to explain why I was watching her play with herself.
I resigned myself to going to my own bed and finishing by myself.
I hurriedly got undressed and jumped into bed to relieve myself. It felt so good to finally get a grip on my aching cock that I didn't think it would take long at all to cum.
