BJs For Cash

I'm a lesbian in a committed relationship of 3 years. I Iove my girlfriend and would do anything for her. There is one thing I do for her, us that she'll never know or believe. I give blow jobs for money. I don't love doing it, but I do have to admit that there are a lot of things I like about doing it, the money aside. We were really struggling to make ends meet during the covid shutdown and I was propositioned and took him up on it. So now I blow this older rich dude and a few of his friends, and we no longer hurt for money. You wouldn't believe how much money these old dudes pay to have a young girl blow them. They take no longer than 5-10 minutes to cum. Just like my step dad all those years ago. As much as I hate him for what he did to me back then, he taught me a very valuable and lucrative skill.
What else could I do to earn a hundred bucks every 5 minutes?
