When she got home I was in my room watching my porn movies and didn't here when my sister got home. she must have heard the noise as she came to my room and opened the door to find me laying on my bed masturbating she quickly shut the door and ran to her room I was shocked and scared at first but then I thought maybe this could be an oppurtunity. I got dressed and went to her room as I opened the door she started yelling at me about what a pervert I was. But before she could get really started I told her how I felt about her she seemed stunned and looked at me kind of blankly. Before she could get mad I quickly kissed her and grabbed her pussy and gave it a rub she pushed me away and started telling me that it was wrong and discusting. But I could see that she was wet. I took my pants off then pulled out my fully erect cock even mad as she was she kept staring at it's 8in length and 2in breadth then she started to tell me in a much less sure sounding voice that it was wrong I moved towerds her kissing her she pushed me away I kissed her again and usen my other hand to grab at her pussy through her pant's. As I kissed her a third time I felt the kiss returned even though in between she was still saying tha it was wrong I pulled her shirt off and kissed her again. She returned the kiss strongly and pulled her pants off while I took off her braw. She took her panties off and I quickly Dropped down and began licking it clear of her jucies then began probing her cunt with my tounge as she moaned i inserted my fingers into her pussy moving them faster and faster until she orgasmed.
