Anybody Else?

Any other guys ever sexually crossed the line with your sister or mother? With me it was my sister. She was 17 and I was 20. One night I got a call from a friend. He said my sister was at a party and too hammered to drive. He took her keys, but didn't wanna get her in dutch with my parents. OK, I went to get her.
When I got there things we thin. My friend told me she had gone upstairs with a guy. We went up to get her. Checked a couple of bedrooms and found her. Guy was gone and she was naked laying on a bed. I told him to go back downstairs I would handle it. I shut the door and started trying to find her clothes. She was a ragdoll and so drunk she didn't know who I was. She kept mumbling the name "Brad". I got a good look at all her goods . Seen her naked before but not this close up. I got her panties up to her thighs when I realized my cock was sending me an SOS. I really didn't even think about it. I rolled her over face down, walked over and locked the door. Dropped my pants and slid my cock in her wet little pussy. It was a lifeless fuck but her pussy was tight. I finished, dressed her, took her home and snuck her in her room. She never knew and I didn't tell anyone.
