I come home looking for my brother and catch my sister-in-law in lingerie

This man walks into his brother's house thinking his wife would be at work like every morning. However, it turns out his brother isn't home... but his sister-in-law is. And she's in bed wearing sexy lingerie, about to masturbate. What a great body she has. Looks like this MILF is going to use her brother-in-law to fuck...!!
