Can't Remember The Name

I am on the hunt for the story I read a few years ago and would like to reread it.

I can't remember the exact details because it's been at least a year or 2 from reading it, but what I do remember is the series is a two part series. The first series is about a huge shy top who meets a very outgoing bottom who at first just wants the top for sex but ends up falling for him. I also remember the top having a brother who is boss in a mob or is considered a gangster. The shy brother asks the older brother to help style him and let's him tattoo a few things on his to make him look cool.

The second story is about the older brother who actually falls in love with one of his younger brothers' friends from college who is technically a nerd. I remember both of the brothers being huge in size (very tall and muscular), I also remember that both brothers have black hair and the old brother ends up cutting his hair maybe because he ends up going to jail.

Someone, please help me find this 😩🙏
