When the virgin makes her brother's best friend an offer he can't refuse — her.

As the CEO of a multimillion dollar company, I pride myself on being in control.

I'm rarely rattled, until my best friend's little sister makes me an offer I can't resist. Sweet, sexy, big-hearted CJ wants me to be her teacher. In the bedroom.

And oh hell, does she ever have a detailed lesson plan. Seven nights of seduction. Seven nights to teach her everything I know between the sheets.

The only rule in our classroom is the one I make—we won't catch feelings.

But as we work our way through every single sinfully sexy lesson, it turns out I'm learning something too.

The trouble is I don't have the answer key to what to do when I fall hard for her.
