College Brat Consequences (La Société d'Eros #3)
A.J. Bressmeier

Mr. Nashten is a new teacher, but what Christy doesn’t know is he can handle her bad girl ways and then some. Christy is surprised when she finds leather whips and vibrating toys in her immediate future and even more surprised when she discovers she can’t live without them.
But is she going to stop being a brat? Not hardly. She’s just going to use that to get more of his attention and damn whatever delicious consequences follow.
This is part of La Société d'Eros series of books.
