Did Sis

I’m thirteen years old. My older sister is eighteen and a slut. She’s been nothing but problems since becoming a teenager. So the other night she came home pissed fall down drunk. She does this shit often knowing full well that mom works evenings and isn’t home until one am. So it was ten thirty and she passes out on the kitchen floor. Her legs were apart in a short skirt and she wasn’t wearing panties so her snatch was in full display. So I laid down between her legs and explored her pussy with my fingers and face. It is wrong but smelling her snatch and the sight got me very hard. I parted her legs and put my dick in her. She woke up and grabbed my ass and said fuck me. Which I did. After I came I helped get her to bed and she asked me to fuck her again and I did again. She is my first. Pretty sweet. She told me the next day that won’t happen again but I bet it will.
