Ok now that my little sis is 18 I do want to fuck the shit out of her.  She walks around the house in her panties when it's just the family because its all girls and me.  She catches me looking at her all the time and says "stop staring at me you little pervert or fag but I deal with it because I don't want her to stop walking around in her panties.  A few weeks ago her friend called me and said to hide it from my mom but she got to drunk and was passed out and needed a ride home.  I showed up about a half hour later and she was crawling on the floor her sweatpants were half way down her legs and all I could see was her her pink lacy super tight panties jammed all the way up her sexy ass crack.  When I got her home I took her up to her bed room.  She kept telling me I was the greatest brother and how much she loved me.  Then she said "for not telling mom on me you can fuck me all you want tonight". I told her to go to sleep because she was drunk and didn't know what she was talking about.  After about an hour I was regretting not taking my chance so I went back to her room and shook her and tried to wake her up but she was out.  I figured an earthquake wouldn't wake her up so I pulled her sweatpants down showing her cute pink lacy panties and perfect ass.  I then pulled her panties down.  Now I knew it was wrong but I did it anyways I fucked her passed out 18 yr old pussy for a few hours.  The next I thought I was gonna be in trouble with her because I fucked her real hard she came up to me and asked how she got home last night I told her that her friend called me and asked me to pick her up.  She said "oh, well did they say that I fell or something because my entire body is sore as hell I feel like I got hit by a bus."  I told her that she was trashed and couldn't even walk or talk.  She laughed and grabbed her head and I smiled at her and said "hangovers suck don't they?"  She said "they sure do" then as she walked away only wearing the short t-shirt from last night and some tight full back satin panties that were white with pink flowers on them she then turned her head and said "thank you for picking me up and not telling mom."  I smiled at her and said "no problem anytime you get that drunk I will pick you up.  Then she said "well thank you for everything again I love you."  I said I love you to little sis."  She smiled and walked away shaking her sexy ass in those tight panties.  I don't believe she remembers anything.  By far the greatest day of my life.
