Drunk sister

My sister who’s 6 years older than me. I was 15 at the age of the hormones kicking in anyways. My sister came home after being out with her friends and she was drunk I mean really drunk. Our parents were away witch is probably why she got drunk. I heard a car pull up outside our house and the door open. I looked out my window and saw my sister zip zagging to the door. She walked in the house and bounced her way to the bathroom off the walls in the hallway.
After like 10 minutes she was still in the bathroom so I got up to check on her. I opened the door and she was laying on her floor on her back her skirt and panties down around her ankles she got one knee leaning against the vanity and the other knee on the floor so her legs are spread open. Her pussy was shaved smooth her pussy lips were beautiful lite pink. I sat down next to her rubbing my hand on her inner thigh asking her if she ok. Sliding my hand up closer to her pussy rubbing my thumb on her lip. When she woke up and saying she’s fine and why was I in her bedroom. I explained to her she was in the bathroom and helped her to her bed as she’s taken baby steps because she doesn’t realize her panties are around her ankles she had already lost her skirt.
She fell on her bed on her side then she turned on her back and was out like a light with in minutes. I’m laying on the side of her on the bed rubbing her stomach sliding my hand lower and lower. I sat up on the bed and unbuttoned her shirt and slid it over her shoulders and off her. I then pulled her on her side so I could get my hand behind her to undo her bra hooks. Then I slid her bra over her shoulders.
I got off the bed I wanted a good look at her the only thing she had on was her heel shoes and her panties wrapped around one ankle. I put her feet together so I could open her knees as far as I could. I then picked her feet up so I could squeeze under them her pussy was now in my face I put my hands on her waist and just started eating her out I could feel her getting wetter and wetter.
I got up pulled my shorts off got between her legs and sat down between them. I reached forward and cupped her tits and squeezed her nipples. I slowly slid my hard dick in her pussy she was so warm and wet. Now I’m fucking my sister and pulling on her nipples she let out a few moans but never woke up. I ended up pulling out and shot my load on her stomach.
