On Purpose
I really love the kinky stuff. I love older men, and I love the thought of family stuff too. I decided to lay a little trap for my brother.
I got myself real wet then took my panties off and left them on his bed. I spied through the airvent that connects our rooms. I saw him pick them up and smell them. I wanted him to jack off but instead he just put them back on his bed. I figured he would do it later.
Instead though, my sister was collecting washing and she found the panties. I watched as she picked them up, smelled them and then looked around herself. She stood with my panties in her hand and started to masturbate. I saw her hand go into her panties and she started to smell mine real good. When she cummed she gasped and whispered 'Oh fuck' over and over and over. I even saw her lick my panty crotch.
I went to find a pair of hers to see what its like.
