Yui, my sister-in-law, lives with me in a two-generation house as my brother's wife. She is always kind and cute, but ever since our parents left, something has started to change... As I was captivated by Yui cleaning in a lewd outfit, she seduced me and we had sex with her inside. Since then, she comes into the bath, gives me fellatio next to my brother while he's sleeping... And today, I also had sex with her inside...
