My sister is 3 years older than I am. When I was 13 she called out for me to come into her room, the door was closed so I knocked. she told me to come in. She was sitting on her bed covered with a sheet. She said come here, so I did. She then threw back the sheet and grabbed my hand and made me put a finger in her pussy. She said, "keep doing that, it'll feel better." I said, "how if it feels gross?" Then I pulled my finger out and left. Ever since I wish I would have kept fingering her, and I want to go visit her and fuck her. The best sex I ever had was with one of my ex girlfriends while I was thinking about my sister.

I know this probably won't get any comments as it's not a great sex story between siblings and that's fine with me, although I would like to read your comments, but it's a true confession. Thanks for reading.
