My name is Allan, 27 years of age and I live with my sister Cynthia who is 25. We're originally from Boston Mass., and I moved to San Francisco 2 years ago cause I was transfered to our sattelite office in SFO. My sister followed suit a year ago and asked if she could stay with me for the time being till she can get a job and settle to her own place. Since I rented a 2 bedroom apartment, I offered my sis the use of the other bedroom.
My little secret with sis started two months ago when she asked if she could go party with some friends at the local bar & disco. Sis told me that she should be back around 1 am. I told her " sure, i'll wait up for ya so I can open the door." It was about 2:30 am when the doorbell rang so I opened the door and saw two of her frien
ds carrying Cynthia inside the apartment. I asked " what happened?" Her friends said " oh, she's wasted, cold drunk and dead to the world." I smiled and told them I can take care of sis from here so they can be on their way.
I carried my sister to her room and lay her down on her bed. I noticed she still had spots of puke on her dress so I tried to wake her up so she could change her dress and freshen up but she was dead to the world. I tapped her cheeks to try to wake her up again to ask if she would like me to make some coffee for her, but still no response. So I just made the decision to change her clothes for her.
I pulled off her shoes and started to unbutton her dress, man it was a mess!! I lifted her dress and pulled it off so she was lying on her bed with just her underwear. I went to the bathroom to get a wet towel to wipe off the puke off her.As I was wiping the mess off her body I noticed that her bra and panty were also moist with puke so I figured I might as well change her underwear as well. I unhooked her bra and pulled it out and slipped her thongs down. I walked towards the dresser to get fresh underwear for her, but as I looked back at the bed I started to stare at my naked sister for a long time. Lying in bed was the most gorgeous thing i've ever seen. Her beautiful 36 cupsize breast with little pink nipples just waiting to be devoured. Her bushy volcano waiting to errupt.I could see the line in her pussy underneath that bushy black pubic hair. Many kinky things started to enter my mind but something was whispering in my ear THAT IS WRONG!! But after a few seconds, I developed a tremendous BONER and all hell broke loose. I figured Cynthia's spaced out anyway so she wouldn't know what happened.
I sat down beside her bed and stuck my finger inside her mouth to see if she would wake up, yup still lucky. I played with her tongue with my finger to see if there was any movement and there was none at all. My God, she's wasted. I went down a bit and started to caress her tits, moved my head down and licked her nipples with my tongue. I sqeezed her tits ever so gently while sucking her nipples and all I heard was Cynthia's snoring. I was giggling with amazement on how densed my sister was. I moved my right hand down to her pussy and started to massage it with my fingers. I slid my middle finger down her line in an up and down motion until I could bury my finger as deep as I could. I stopped for a moment and spread her legs apart as far as she could and finally had a clear opening at her volcano.I spread the lips of her pussy and played with her clit but since she was out cold her vagina was dry. I got the baby oil on top of her dresser and squirted a few drops at a time down her pussy. Spread the lips once again and squirted more baby oil down her pussy till it reached her asshole. I threw the bottle of baby oil down the floor and played with her pussy again which was now slippery wet. I slid my finger a quarter of the way inside her pussy trying to get as much baby oil inside as I can but careful enough not to jolt her. I ran my finger down her asshole and lubricated it with oil. As I was pressing oil around my sisters asshole my finger started to slid inside her ass. I slid my finger inside as gently as I could and as far as I could and started the slow fucking motion. I slid my finger in and out but constantly staring at Cynthia if she would wake up but she was still out cold.
At this point my pecker was ready to explode and my pecker head was turning purple blue with anticipation. I knelt down in between my sisters legs and started playing with her pussy again but this time with the head of my pecker. Moved the head up and down her line enjoying every moment of it. Then the head of my pecker finally rested on the opening of her pussy, I paused for a moment, hesitated a little bit then pushed in halfway. Noticing that Cynthia was still snoring, I pushed in all the way till my pecker was burried deep inside her. I pulled up slowly and pushed in again till I was actually fucking my sister. As I was about to explode, Cynthia's head started to turn from side to side, I figured this is it, she is going to get really pissed. Finally I exploded all my semen on top her belly and just dropped down the floor with exhaustion. I looked up at Cynthia's face and wouldn't you know it, she was snoring again. Unbelievable. I cleaned her up with the wet towel and slipped on her jammies, turned off the lights and went to bed.
The next morning, I went down to the kitchen to have my usual morning coffee. Cynthia was up and cooking breakfast. "Good morning sweetie" Cynthia said. " Morning Babe" I replied. " by the way, who took me home last night?" she uttered. " your friends, but they were pretty messed up too so I took you up to your room" " Oh, thanks for putting on my jammies" Cynthia said." no prob" I answered.
Cynthia suddenly turned towards me and said " Someone must have taken advantage of me in the bar last night cause my pussy and ASS is so damn sore"    " No, it was me" I said. Cynthia screamed " you serious?" I said " NO..."    Cynthia smiled and said " JERK!!"
