My sister-in-law usually wanders around the house in a defenseless outfit, so I don't know where to look. On days when I get an erection, she jumps on my erect cock with shining eyes. Then, to my surprise, she begs me, "Hey, big brother... let me lick it!" She pulls down my pants and takes my cock in her mouth! She even takes it deep in her throat and doesn't let go, making me cum until I cum! Of course, that doesn't stop there, and she makes me cum inside her many times and abuses my cock!
